scsi: ufs: ufshpb: Add HPB 2.0 support
Version 2.0 of HBP supports reads of varying sizes from 4KB to 1MB. A read operation <= 32KB is supported as single HPB read. A read between 36KB and 1MB is supported by a combination of write buffer command and HPB read command to deliver more PPN. The write buffer commands may not be issued immediately due to busy tags. To use HPB read more aggressively, the driver can requeue the write buffer command. The requeue threshold is implemented as timeout and can be modified with requeue_timeout_ms entry in sysfs. [mkp: REQ_OP_DRV_* and blk_rq_is_passthrough()] Link: https://lore.kernel.org/r/20210712090025epcms2p3b3d94f6f1b2cfa394e3d9ba130ca0fa7@epcms2p3 Tested-by: Can Guo <cang@codeaurora.org> Tested-by: Stanley Chu <stanley.chu@mediatek.com> Reviewed-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org> Reviewed-by: Can Guo <cang@codeaurora.org> Reviewed-by: Bean Huo <beanhuo@micron.com> Reviewed-by: Stanley Chu <stanley.chu@mediatek.com> Signed-off-by: Daejun Park <daejun7.park@samsung.com> Signed-off-by: Martin K.

scsi: ufs: ufshpb: Introduce Host Performance Buffer feature
Implement Host Performance Buffer (HPB) initialization and add function calls to UFS core driver. NAND flash-based storage devices, including UFS, have mechanisms to translate logical addresses of I/O requests to the corresponding physical addresses of the flash storage. In UFS, logical-to-physical-address (L2P) map data, which is required to identify the physical address for the requested I/Os, can only be partially stored in SRAM from NAND flash. Due to this partial loading, accessing the flash address area, where the L2P information for that address is not loaded in the SRAM, can result in serious performance degradation. The basic concept of HPB is to cache L2P mapping entries in host system memory so that both physical block address (PBA) and logical block address (LBA) can be delivered in HPB read command. The HPB read command allows to read data faster than a regular read command in UFS since it provides the physical address (HPB Entry) of the desired logical block in addition to its logical address. The UFS device can access the physical block in NAND directly without searching and uploading L2P mapping table. This improves read performance because the NAND read operation for uploading L2P mapping table is removed. In HPB initialization, the host checks if the UFS device supports HPB feature and retrieves related device capabilities. Then, HPB parameters are configured in the device. Total start-up time of popular applications was measured and the difference observed between HPB being enabled and disabled. Popular applications are 12 game apps and 24 non-game apps. Each test cycle consists of running 36 applications in sequence. We repeated the cycle for observing performance improvement by L2P mapping cache hit in HPB. The following is the test environment: - kernel version: 4.4.0 - RAM: 8GB - UFS 2.1 (64GB) Results: +-------+----------+----------+-------+ | cycle | baseline | with HPB | diff | +-------+----------+----------+-------+ | 1 | 272.4 | 264.9 | -7.5 | | 2 | 250.4 | 248.2 | -2.2 | | 3 | 226.2 | 215.6 | -10.6 | | 4 | 230.6 | 214.8 | -15.8 | | 5 | 232.0 | 218.1 | -13.9 | | 6 | 231.9 | 212.6 | -19.3 | +-------+----------+----------+-------+ We also measured HPB performance using iozone: $ iozone -r 4k -+n -i2 -ecI -t 16 -l 16 -u 16 -s $IO_RANGE/16 -F \ mnt/tmp_1 mnt/tmp_2 mnt/tmp_3 mnt/tmp_4 mnt/tmp_5 mnt/tmp_6 mnt/tmp_7 \ mnt/tmp_8 mnt/tmp_9 mnt/tmp_10 mnt/tmp_11 mnt/tmp_12 mnt/tmp_13 \ mnt/tmp_14 mnt/tmp_15 mnt/tmp_16 Results: +----------+--------+---------+ | IO range | HPB on | HPB off | +----------+--------+---------+ | 1 GB | 294.8 | 300.87 | | 4 GB | 293.51 | 179.35 | | 8 GB | 294.85 | 162.52 | | 16 GB | 293.45 | 156.26 | | 32 GB | 277.4 | 153.25 | +----------+--------+---------+ Link: https://lore.kernel.org/r/20210712085830epcms2p8c1288b7f7a81b044158a18232617b572@epcms2p8 Reported-by: kernel test robot <lkp@intel.com> Tested-by: Bean Huo <beanhuo@micron.com> Tested-by: Can Guo <cang@codeaurora.org> Tested-by: Stanley Chu <stanley.chu@mediatek.com> Reviewed-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org> Reviewed-by: Bart Van Assche <bvanassche@acm.org> Reviewed-by: Can Guo <cang@codeaurora.org> Reviewed-by: Bean Huo <beanhuo@micron.com> Reviewed-by: Stanley Chu <stanley.chu@mediatek.com> Acked-by: Avri Altman <Avri.Altman@wdc.com> Signed-off-by: Daejun Park <daejun7.park@samsung.com> Signed-off-by: Martin K.

dmanegine: idxd: add software command status
Enabling device and wq returns standard errno and that does not provide enough details to indicate what exactly failed. The hardware command status is only 8bits. Expand the command status to 32bits and use the upper 16 bits to define software errors to provide more details on the exact failure. Bit 31 will be used to indicate the error is software set as the driver is using some of the spec defined hardware error as well.

dma-buf: Delete the DMA-BUF attachment sysfs statistics
The DMA-BUF attachment statistics form a subset of the DMA-BUF
sysfs statistics that recently merged to the drm-misc tree. They are not
UABI yet since they have not merged to the upstream Linux kernel.
Since there has been a reported a performance regression due to the
overhead of sysfs directory creation/teardown during
dma_buf_attach()/dma_buf_detach(), this patch deletes the DMA-BUF
attachment statistics from sysfs.

Networking fixes for 5.14-rc2, including fixes from bpf and netfilter.
Current release - regressions:
- sock: fix parameter order in sock_setsockopt()
Current release - new code bugs:
- netfilter: nft_last:
- fix incorrect arithmetic when restoring last used
- honor NFTA_LAST_SET on restoration
Previous releases - regressions:
- udp: properly flush normal packet at GRO time
- sfc: ensure correct number of XDP queues; don't allow enabling the
feature if there isn't sufficient resources to Tx from any CPU
- dsa: sja1105: fix address learning getting disabled on the CPU port
- mptcp: addresses a rmem accounting issue that could keep packets
in subflow receive buffers longer than necessary, delaying
MPTCP-level ACKs
- ip_tunnel: fix mtu calculation for ETHER tunnel devices
- do not reuse skbs allocated from skbuff_fclone_cache in the napi
skb cache, we'd try to return them to the wrong slab cache
- tcp: consistently disable header prediction for mptcp
Previous releases - always broken:
- bpf: fix subprog poke descriptor tracking use-after-free
- ipv6:
- allocate enough headroom in ip6_finish_output2() in case
iptables TEE is used
- tcp: drop silly ICMPv6 packet too big messages to avoid
expensive and pointless lookups (which may serve as a DDOS
vector)
- make sure fwmark is copied in SYNACK packets
- fix 'disable_policy' for forwarded packets (align with IPv4)
- netfilter: conntrack: do not renew entry stuck in tcp SYN_SENT state
- netfilter: conntrack: do not mark RST in the reply direction coming
after SYN packet for an out-of-sync entry
- mptcp: cleanly handle error conditions with MP_JOIN and syncookies
- mptcp: fix double free when rejecting a join due to port mismatch
- validate lwtstate->data before returning from skb_tunnel_info()
- tcp: call sk_wmem_schedule before sk_mem_charge in zerocopy path
- mt76: mt7921: continue to probe driver when fw already downloaded
- bonding: fix multiple issues with offloading IPsec to (thru?) bond
- stmmac: ptp: fix issues around Qbv support and setting time back
- bcmgenet: always clear wake-up based on energy detection
Misc:
- sctp: move 198 addresses from unusable to private scope
- ptp: support virtual clocks and timestamping
- openvswitch: optimize operation for key comparison

Pull networking fixes from Jakub Kicinski.
"Including fixes from bpf and netfilter.
Current release - regressions:
- sock: fix parameter order in sock_setsockopt()
Current release - new code bugs:
- netfilter: nft_last:
- fix incorrect arithmetic when restoring last used
- honor NFTA_LAST_SET on restoration
Previous releases - regressions:
- udp: properly flush normal packet at GRO time
- sfc: ensure correct number of XDP queues; don't allow enabling the
feature if there isn't sufficient resources to Tx from any CPU
- dsa: sja1105: fix address learning getting disabled on the CPU port
- mptcp: addresses a rmem accounting issue that could keep packets in
subflow receive buffers longer than necessary, delaying MPTCP-level
ACKs
- ip_tunnel: fix mtu calculation for ETHER tunnel devices
- do not reuse skbs allocated from skbuff_fclone_cache in the napi
skb cache, we'd try to return them to the wrong slab cache
- tcp: consistently disable header prediction for mptcp
Previous releases - always broken:
- bpf: fix subprog poke descriptor tracking use-after-free
- ipv6:
- allocate enough headroom in ip6_finish_output2() in case
iptables TEE is used
- tcp: drop silly ICMPv6 packet too big messages to avoid
expensive and pointless lookups (which may serve as a DDOS
vector)
- make sure fwmark is copied in SYNACK packets
- fix 'disable_policy' for forwarded packets (align with IPv4)
- netfilter: conntrack:
- do not renew entry stuck in tcp SYN_SENT state
- do not mark RST in the reply direction coming after SYN packet
for an out-of-sync entry
- mptcp: cleanly handle error conditions with MP_JOIN and syncookies
- mptcp: fix double free when rejecting a join due to port mismatch
- validate lwtstate->data before returning from skb_tunnel_info()
- tcp: call sk_wmem_schedule before sk_mem_charge in zerocopy path
- mt76: mt7921: continue to probe driver when fw already downloaded
- bonding: fix multiple issues with offloading IPsec to (thru?) bond
- stmmac: ptp: fix issues around Qbv support and setting time back
- bcmgenet: always clear wake-up based on energy detection
Misc:
- sctp: move 198 addresses from unusable to private scope
- ptp: support virtual clocks and timestamping
- openvswitch: optimize operation for key comparison"

dmaengine: idxd: Add wq occupancy information to sysfs attribute
Add occupancy information to wq sysfs attribute. Attribute will show wq occupancy data if "WQ Occupancy Support" field in WQCAP is 1. It displays the number of entries currently in this WQ. This is provided as an estimate and should not be relied on to determine whether there is space in the WQ. The data is to provide information to user apps for flow control.

f2fs: add sysfs nodes to get GC info for each GC mode
Added gc_reclaimed_segments and gc_segment_mode sysfs nodes. 1) "gc_reclaimed_segments" shows how many segments have been reclaimed by GC during a specific GC mode. 2) "gc_segment_mode" is used to control for which gc mode the "gc_reclaimed_segments" node shows.

f2fs-for-5.14-rc1
In this round, we've improved the compression support especially for Android
such as allowing compression for mmap files, replacing the immutable bit with
internal bit to prohibits data writes explicitly, and adding a mount option,
"compress_cache", to improve random reads. And, we added "readonly" feature to
compact the partition w/ compression enabled, which will be useful for Android
RO partitions.
Enhancement:
- support compression for mmap file
- use an f2fs flag instead of IMMUTABLE bit for compression
- support RO feature w/ extent_cache
- fully support swapfile with file pinning
- improve atgc tunability
- add nocompress extensions to unselect files for compression
Bug fix:
- fix false alaram on iget failure during GC
- fix race condition on global pointers when there are multiple f2fs instances
- add MODULE_SOFTDEP for initramfs
As usual, we've also cleaned up some places for better code readability.
(e.g., sysfs/feature, debugging messages, slab cache name, and docs)

Pull CXL (Compute Express Link) updates from Dan Williams:
"This subsystem is still in the build-out phase as the bulk of the
update is improvements to enumeration and fleshing out the device
model. In terms of new features, more mailbox commands have been added
to the allowed-list in support of persistent memory provisioning
support targeting v5.15.
The critical update from an enumeration perspective is support for the
CXL Fixed Memory Window Structure that indicates to Linux which system
physical address ranges decode to the CXL Host Bridges in the system.
This allows the driver to detect which address ranges have been mapped
by firmware and what address ranges are available for future hotplug.
So, again, mostly skeleton this round, with more meat targeting v5.15.
Summary:
- Add support for the CXL Fixed Memory Window Structure, a recent
extension of the ACPI CEDT (CXL Early Discovery Table)
- Add infrastructure for component registers
- Add HDM (Host-managed device memory) decoder definitions

perf/x86/intel/uncore: Add alias PMU name
A perf PMU may have two PMU names. For example, Intel Sapphire Rapids server supports the discovery mechanism. Without the platform-specific support, an uncore PMU is named by a type ID plus a box ID, e.g., uncore_type_0_0, because the real name of the uncore PMU cannot be retrieved from the discovery table. With the platform-specific support later, perf has the mapping information from a type ID to a specific uncore unit. Just like the previous platforms, the uncore PMU is named by the real PMU name, e.g., uncore_cha_0. The user scripts which work well with the old numeric name may not work anymore. Add a new attribute "alias" to indicate the old numeric name. The following userspace perf tool patch will handle both names. The user scripts should work properly with the updated perf tool.

ptp: support ptp physical/virtual clocks conversion
Support ptp physical/virtual clocks conversion via sysfs. There will be a new attribute n_vclocks under ptp physical clock sysfs. - In default, the value is 0 meaning only ptp physical clock is in use. - Setting the value can create corresponding number of ptp virtual clocks to use. But current physical clock is guaranteed to stay free running. - Setting the value back to 0 can delete virtual clocks and back use physical clock again. Another new attribute max_vclocks control the maximum number of ptp vclocks. Signed-off-by: Yangbo Lu <yangbo.lu@nxp.com> Signed-off-by: David S. Miller <davem@davemloft.net> |

This was a reasonably active cycle for documentation; this pull includes:
- Some kernel-doc cleanups. That script is still regex onslaught from
hell, but it has gotten a little better.
- Improvements to the checkpatch docs, which are also used by the tool
itself.
- A major update to the pathname lookup documentation.
- Elimination of :doc: markup, since our automarkup magic can create
references from filenames without all the extra noise.
- The flurry of Chinese translation activity continues.
Plus, of course, the usual collection of updates, typo fixes, and warning
fixes.

powerpc/papr_scm: Make 'perf_stats' invisible if perf-stats unavailable
In case performance stats for an nvdimm are not available, reading the
'perf_stats' sysfs file returns an -ENOENT error. A better approach is
to make the 'perf_stats' file entirely invisible to indicate that
performance stats for an nvdimm are unavailable.
So this patch updates 'papr_nd_attribute_group' to add a 'is_visible'
callback implemented as newly introduced 'papr_nd_attribute_visible()'
that returns an appropriate mode in case performance stats aren't
supported in a given nvdimm.
Also the initialization of 'papr_scm_priv.stat_buffer_len' is moved
from papr_scm_nvdimm_init() to papr_scm_probe() so that it value is
available when 'papr_nd_attribute_visible()' is called during nvdimm
initialization.
Even though 'perf_stats' attribute is available since v5.9, there are
no known user-space tools/scripts that are dependent on presence of its
sysfs file. Hence I dont expect any user-space breakage with this
patch.
Fixes:

f2fs: clean up /sys/fs/f2fs/<disk>/features
Let's create /sys/fs/f2fs/<disk>/feature_list/ to meet sysfs rule.
Note that there are three feature list entries:
1) /sys/fs/f2fs/features
: shows runtime features supported by in-kernel f2fs along with Kconfig.
- ref. F2FS_FEATURE_RO_ATTR()
2) /sys/fs/f2fs/$s_id/features <deprecated>
: shows on-disk features enabled by mkfs.f2fs, used for old kernels. This
won't add new feature anymore, and thus, users should check entries in 3)
instead of this 2).
3) /sys/fs/f2fs/$s_id/feature_list
: shows on-disk features enabled by mkfs.f2fs per instance, which follows
sysfs entry rule where each entry should expose single value.
This list covers old feature list provided by 2) and beyond. Therefore,
please add new on-disk feature in this list only.

add support for Dell privacy driver for the Dell units equipped hardware privacy design, which protect users privacy of audio and camera from hardware level. Once the audio or camera privacy mode activated, any applications will not get any audio or video stream when user pressed ctrl+F4 hotkey, audio privacy mode will be enabled, micmute led will be also changed accordingly The micmute led is fully controlled by hardware & EC(embedded controller) and camera mute hotkey is Ctrl+F9. Currently design only emits SW_CAMERA_LENS_COVER event while the camera lens shutter will be changed by EC & HW(hardware) control *The flow is like this: 1) User presses key. HW does stuff with this key (timeout timer is started) 2) WMI event is emitted from BIOS to kernel 3) WMI event is received by dell-privacy 4) KEY_MICMUTE emitted from dell-privacy 5) Userland picks up key and modifies kcontrol for SW mute 6) Codec kernel driver catches and calls ledtrig_audio_set 7) dell-privacy notifies EC, the timeout is cancelled and the HW mute is activated. If the EC is not notified then the HW mic mute will activate when the timeout triggers, just a bit later than with the active ack.

USB: misc: Add onboard_usb_hub driver
The main issue this driver addresses is that a USB hub needs to be powered before it can be discovered. For discrete onboard hubs (an example for such a hub is the Realtek RTS5411) this is often solved by supplying the hub with an 'always-on' regulator, which is kind of a hack. Some onboard hubs may require further initialization steps, like changing the state of a GPIO or enabling a clock, which requires even more hacks. This driver creates a platform device representing the hub which performs the necessary initialization. Currently it only supports switching on a single regulator, support for multiple regulators or other actions can be added as needed. Different initialization sequences can be supported based on the compatible string. Besides performing the initialization the driver can be configured to power the hub off during system suspend. This can help to extend battery life on battery powered devices which have no requirements to keep the hub powered during suspend. The driver can also be configured to leave the hub powered when a wakeup capable USB device is connected when suspending, and power it off otherwise. Technically the driver consists of two drivers, the platform driver described above and a very thin USB driver that subclasses the generic driver. The purpose of this driver is to provide the platform driver with the USB devices corresponding to the hub(s) (a hub controller may provide multiple 'logical' hubs, e.g. one to support USB 2.0 and another for USB 3.x). Note: the current series only supports hubs connected directly to a root hub (through xhci-plat), support for other configurations could be added if needed.

dmabuf: Add the capability to expose DMA-BUF stats in sysfs
Overview ======== The patch adds DMA-BUF statistics to /sys/kernel/dmabuf/buffers. It allows statistics to be enabled for each DMA-BUF in sysfs by enabling the config CONFIG_DMABUF_SYSFS_STATS. The following stats will be exposed by the interface: /sys/kernel/dmabuf/buffers/<inode_number>/exporter_name /sys/kernel/dmabuf/buffers/<inode_number>/size /sys/kernel/dmabuf/buffers/<inode_number>/attachments/<attach_uid>/device /sys/kernel/dmabuf/buffers/<inode_number>/attachments/<attach_uid>/map_counter The inode_number is unique for each DMA-BUF and was added earlier [1] in order to allow userspace to track DMA-BUF usage across different processes. Use Cases ========= The interface provides a way to gather DMA-BUF per-buffer statistics from production devices. These statistics will be used to derive DMA-BUF per-exporter stats and per-device usage stats for Android Bug reports. The corresponding userspace changes can be found at [2]. Telemetry tools will also capture this information(along with other memory metrics) periodically as well as on important events like a foreground app kill (which might have been triggered by Low Memory Killer). It will also contribute to provide a snapshot of the system memory usage on other events such as OOM kills and Application Not Responding events. Background ========== Currently, there are two existing interfaces that provide information about DMA-BUFs. 1) /sys/kernel/debug/dma_buf/bufinfo debugfs is however unsuitable to be mounted in production systems and cannot be considered as an alternative to the sysfs interface being proposed. 2) proc/<pid>/fdinfo/<fd> The proc/<pid>/fdinfo/<fd> files expose information about DMA-BUF fds. However, the existing procfs interfaces can only provide information about the buffers for which processes hold fds or have the buffers mmapped into their address space. Since the procfs interfaces alone cannot provide a full picture of all DMA-BUFs in the system, there is the need for an alternate interface to provide this information on production systems. The patch contains the following major improvements over v1: 1) Each attachment is represented by its own directory to allow creating a symlink to the importing device and to also provide room for future expansion. 2) The number of distinct mappings of each attachment is exposed in a separate file. 3) The per-buffer statistics are now in /sys/kernel/dmabuf/buffers inorder to make the interface expandable in future. All of the improvements above are based on suggestions/feedback from Daniel Vetter and Christian König. A shell script that can be run on a classic Linux environment to read out the DMA-BUF statistics can be found at [3](suggested by John Stultz).

cxl/acpi: Introduce cxl_decoder objects
A cxl_decoder is a child of a cxl_port. It represents a hardware decoder
configuration of an upstream port to one or more of its downstream
ports. The decoder is either represented in CXL standard HDM decoder
registers (see CXL 2.0 section 8.2.5.12 CXL HDM Decoder Capability
Structure), or it is a static decode configuration communicated by
platform firmware (see the CXL Early Discovery Table: Fixed Memory
Window Structure).
The firmware described and hardware described decoders differ slightly
leading to 2 different sub-types of decoders, cxl_decoder_root and
cxl_decoder_switch. At the root level the decode capabilities restrict
what can be mapped beneath them. Mid-level switch decoders are
configured for either acclerator (type-2) or memory-expander (type-3)
operation, but they are otherwise agnostic to the type of memory
(volatile vs persistent) being mapped.
Here is an example topology from a single-ported host-bridge environment
without CFMWS decodes enumerated.

cxl/acpi: Introduce the root of a cxl_port topology
While CXL builds upon the PCI software model for enumeration and endpoint control, a static platform component is required to bootstrap the CXL memory layout. Similar to how ACPI identifies root-level PCI memory resources, ACPI data enumerates the address space and interleave configuration for CXL Memory. In addition to identifying host bridges, ACPI is responsible for enumerating the CXL memory space that can be addressed by downstream decoders. This is similar to the requirement for ACPI to publish resources via the _CRS method for PCI host bridges. Specifically, ACPI publishes a table, CXL Early Discovery Table (CEDT), which includes a list of CXL Memory resources, CXL Fixed Memory Window Structures (CFMWS). For now, introduce the core infrastructure for a cxl_port hierarchy starting with a root level anchor represented by the ACPI0017 device. Follow on changes model support for the configurable decode capabilities of cxl_port instances, i.e. CXL switch support.

usb: gadget: u_audio: add real feedback implementation
This adds interface between userspace and feedback endpoint to report real feedback frequency to the Host. Current implementation adds new userspace interface ALSA mixer control "Capture Pitch 1000000" (similar to aloop driver's "PCM Rate Shift 100000" mixer control) Value in PPM is chosen to have correction value agnostic of the actual HW rate, which the application is not necessarily dealing with, while still retaining a good enough precision to allow smooth clock correction on the playback side, if necessary. Similar to sound/usb/endpoint.c, a slow down is allowed up to 25%. This has no impact on the required bandwidth. Speedup correction has an impact on the bandwidth reserved for the isochronous endpoint. The default allowed speedup is 500ppm. This seems to be more than enough but, if necessary, this is configurable through a module parameter. The reserved bandwidth is rounded up to the next packet size. Usage of this new control is easy to implement in existing userspace tools like alsaloop from alsa-utils.

If the platform has support for this, we expose two additional attributes under USB4 ports: offline and rescan.

PCI: Add sysfs "removable" attribute
A PCI device is "external_facing" if it's a Root Port with the ACPI "ExternalFacingPort" property or if it has the DT "external-facing" property. We consider everything downstream from such a device to be removable by user. We're mainly concerned with consumer platforms with user accessible Thunderbolt ports that are vulnerable to DMA attacks, and we expect those ports to be identified by firmware as "ExternalFacingPort". Devices in traditional hotplug slots can technically be removed, but the expectation is that unless the port is marked with "ExternalFacingPort", such devices are less accessible to user / may not be removed by end user, and thus not exposed as "removable" to userspace. This can be used to implement userspace policies tailored for user removable devices. Eg usage: https://chromium-review.googlesource.com/c/chromiumos/platform2/+/2591812 https://chromium-review.googlesource.com/c/chromiumos/platform2/+/2795038 (code uses such an attribute to remove external PCI devices or disable features on them as needed by the policy desired) Acked-by: Bjorn Helgaas <bhelgaas@google.com> Signed-off-by: Rajat Jain <rajatja@google.com> Link: https://lore.kernel.org/r/20210524171812.18095-2-rajatja@google.com Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org> |

driver core: Move the "removable" attribute from USB to core
Move the "removable" attribute from USB to core in order to allow it to be
supported by other subsystem / buses. Individual buses that want to support
this attribute can populate the removable property of the device while
enumerating it with the 3 possible values -
- "unknown"
- "fixed"
- "removable"
Leaving the field unchanged (i.e. "not supported") would mean that the
attribute would not show up in sysfs for that device. The UAPI (location,
symantics etc) for the attribute remains unchanged.
Move the "removable" attribute from USB to the device core so it can be
used by other subsystems / buses.
By default, devices do not have a "removable" attribute in sysfs.
If a subsystem or bus driver wants to support a "removable" attribute, it
should call device_set_removable() before calling device_register() or
device_add(), e.g.:
device_set_removable(dev, DEVICE_REMOVABLE);
device_register(dev);
The possible values and the resulting sysfs attribute contents are:
DEVICE_REMOVABLE_UNKNOWN -> "unknown"
DEVICE_REMOVABLE -> "removable"
DEVICE_FIXED -> "fixed"
Convert the USB "removable" attribute to use this new device core
functionality. There should be no user-visible change in the location or
semantics of attribute for USB devices.

evm: Refuse EVM_ALLOW_METADATA_WRITES only if an HMAC key is loaded
EVM_ALLOW_METADATA_WRITES is an EVM initialization flag that can be set to
temporarily disable metadata verification until all xattrs/attrs necessary
to verify an EVM portable signature are copied to the file. This flag is
cleared when EVM is initialized with an HMAC key, to avoid that the HMAC is
calculated on unverified xattrs/attrs.
Currently EVM unnecessarily denies setting this flag if EVM is initialized
with a public key, which is not a concern as it cannot be used to trust
xattrs/attrs updates. This patch removes this limitation.

w1: ds2438: support for writing to offset register
Added a sysfs entry to support writing to the offset register on page1. This register is used to calibrate the chip canceling offset errors in the current ADC. This means that, over time, reading the IAD register will not return the correct current measurement, it will have an offset. Writing to the offset register if the two's complement of the current register while passing zero current to the load will calibrate the measurements. This change was tested on real hardware and it was able to calibrate the chip correctly.

iio:ABI docs: Move specific description of out_altvoltageX_frequency to main docs.
The adf4371 has channels that are very closely coupled, so additional documentation is needed to express these constraints.

To avoid this issue, we add a new device specific description to the main docs and remove the one in the device specific file.

iio:ABI docs: Fix issue around repeated definition of out_currentY_raw
This one is challenging as both the places this appears in specific drivers are making 'unusual' uses of what looks like a simple output current channel. As a side note, this was particular bit of ABI occurs in other drivers where the use is much more straight forward e.g. dac/ad5421 This patch attempts to make a best effort of adding it to the main docs but retaining enough information. Both of these drivers probably need specific documents being written to describe their unusual interfaces, but those should be in the main documentation, not under Documentation/ABI.

iio:ABI docs: Fix up duplicate *_calibbias_* documentation for icm42600
This device has the unusual characteristic that the calibbias values have well defined units (more commonly they are tweaks to a DAC) Unfortunately the previous approach of having more specific documentation in sysfs-bus-iio-icm42600 results in warnings during the documentation build and random ordering in the resulting documentation. To avoid this, add a note to the main documentation on this special characteristic for the icm42600.

mm: cma: support sysfs
Since CMA is getting used more widely, it's more important to keep monitoring CMA statistics for system health since it's directly related to user experience. This patch introduces sysfs statistics for CMA, in order to provide some basic monitoring of the CMA allocator. * the number of CMA page successful allocations * the number of CMA page allocation failures These two values allow the user to calcuate the allocation failure rate for each CMA area. e.g.) /sys/kernel/mm/cma/WIFI/alloc_pages_[success|fail] /sys/kernel/mm/cma/SENSOR/alloc_pages_[success|fail] /sys/kernel/mm/cma/BLUETOOTH/alloc_pages_[success|fail] The cma_stat was intentionally allocated by dynamic allocation to harmonize with kobject lifetime management. https://lore.kernel.org/linux-mm/YCOAmXqt6dZkCQYs@kroah.com/ Link: https://lkml.kernel.org/r/20210324230759.2213957-1-minchan@kernel.org Link: https://lore.kernel.org/linux-mm/20210316100433.17665-1-colin.king@canonical.com/ Signed-off-by: Minchan Kim <minchan@kernel.org> Signed-off-by: Colin Ian King <colin.king@canonical.com> Tested-by: Dmitry Osipenko <digetx@gmail.com> Reviewed-by: Dmitry Osipenko <digetx@gmail.com> Reviewed-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org> Reviewed-by: John Hubbard <jhubbard@nvidia.com> Tested-by: Anders Roxell <anders.roxell@linaro.org> Cc: Suren Baghdasaryan <surenb@google.com> Cc: John Dias <joaodias@google.com> Cc: Matthew Wilcox (Oracle) <willy@infradead.org> Cc: Colin Ian King <colin.king@canonical.com> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org> |

f2fs-for-5.13-rc1
In this round, we added a new mount option, "checkpoint_merge", which introduces a kernel thread dealing with the f2fs checkpoints. Once we start to manage the IO priority along with blk-cgroup, the checkpoint operation can be processed in a lower priority under the process context. Since the checkpoint holds all the filesystem operations, we give a higher priority to the checkpoint thread all the time. Enhancement: - introduce gc_merge mount option to introduce a checkpoint thread - improve to run discard thread efficiently - allow modular compression algorithms - expose # of overprivision segments to sysfs - expose runtime compression stat to sysfs Bug fix: - fix OOB memory access by the node id lookup - avoid touching checkpointed data in the checkpoint-disabled mode - fix the resizing flow to avoid kernel panic and race conditions - fix block allocation issues on pinned files - address some swapfile issues - fix hugtask problem and kernel panic during atomic write operations - don't start checkpoint thread in RO And, we've cleaned up some kernel coding style and build warnings.

Networking changes for 5.13.
Core:
- bpf:
- allow bpf programs calling kernel functions (initially to
reuse TCP congestion control implementations)
- enable task local storage for tracing programs - remove the
need to store per-task state in hash maps, and allow tracing
programs access to task local storage previously added for
BPF_LSM
- add bpf_for_each_map_elem() helper, allowing programs to
walk all map elements in a more robust and easier to verify
fashion
- sockmap: support UDP and cross-protocol BPF_SK_SKB_VERDICT
redirection

s390 updates for 5.13 merge window
- fix buffer size for in-kernel disassembler for ebpf programs. - fix two memory leaks in zcrypt driver. - expose PCI device UID as index, including an indicator if the uid is unique. - remove some oprofile leftovers. - improve stack unwinder tests. - don't use gcc atomic builtins anymore, just like all other architectures.

Staging/IIO driver updates for 5.13-rc1
Here is the big set of staging and IIO driver updates for 5.13-rc1.
Lots of little churn in here, and some larger churn as well. Major
things are:
- removal of wimax drivers, no one has this hardware anymore for
this failed "experiment".
- removal of the Google gasket driver, turns out no one wanted
to maintain it or cares about it anymore, so they asked for it
to be removed.
- comedi finally moves out of the staging directory into
drivers/comedi/ This is one of the oldest kernel subsystems
around, being created in the 2.0 kernel days, and was one of
the first things added to drivers/staging/ when that was
created over 15 years ago. It should have been moved out of
staging a long time ago, it's well maintained and used by
loads of different devices in the real world every day. Nice
to see this finally happen.
- so many tiny coding style cleanups it's not funny. Perfect
storm of at least 2 different intern project application
deadlines combined to provide a huge number of new
contributions in this area from people learning how to do
kernel development. Great job to everyone involved here.
There's also the normal updates for IIO drivers with new IIO drivers and
updates all over that subsystem.
All of these have been in linux-next for a while with no reported
issues.

dmaengine: idxd: Add IDXD performance monitor support
Implement the IDXD performance monitor capability (named 'perfmon' in
the DSA (Data Streaming Accelerator) spec [1]), which supports the
collection of information about key events occurring during DSA and
IAX (Intel Analytics Accelerator) device execution, to assist in
performance tuning and debugging.
The idxd perfmon support is implemented as part of the IDXD driver and
interfaces with the Linux perf framework. It has several features in
common with the existing uncore pmu support:
- it does not support sampling
- does not support per-thread counting
However it also has some unique features not present in the core and
uncore support:
- all general-purpose counters are identical, thus no event constraints
- operation is always system-wide
While the core perf subsystem assumes that all counters are by default
per-cpu, the uncore pmus are socket-scoped and use a cpu mask to
restrict counting to one cpu from each socket. IDXD counters use a
similar strategy but expand the scope even further; since IDXD
counters are system-wide and can be read from any cpu, the IDXD perf
driver picks a single cpu to do the work (with cpu hotplug notifiers
to choose a different cpu if the chosen one is taken off-line).
More specifically, the perf userspace tool by default opens a counter
for each cpu for an event. However, if it finds a cpumask file
associated with the pmu under sysfs, as is the case with the uncore
pmus, it will open counters only on the cpus specified by the cpumask.
Since perfmon only needs to open a single counter per event for a
given IDXD device, the perfmon driver will create a sysfs cpumask file
for the device and insert the first cpu of the system into it. When a
user uses perf to open an event, perf will open a single counter on
the cpu specified by the cpu mask. This amounts to the default
system-wide rather than per-cpu counting mentioned previously for
perfmon pmu events. In order to keep the cpu mask up-to-date, the
driver implements cpu hotplug support for multiple devices, as IDXD
usually enumerates and registers more than one idxd device.
The perfmon driver implements basic perfmon hardware capability
discovery and configuration, and is initialized by the IDXD driver's
probe function. During initialization, the driver retrieves the total
number of supported performance counters, the pmu ID, and the device
type from idxd device, and registers itself under the Linux perf
framework.
The perf userspace tool can be used to monitor single or multiple
events depending on the given configuration, as well as event groups,
which are also supported by the perfmon driver. The user configures
events using the perf tool command-line interface by specifying the
event and corresponding event category, along with an optional set of
filters that can be used to restrict counting to specific work queues,
traffic classes, page and transfer sizes, and engines (See [1] for
specifics).
With the configuration specified by the user, the perf tool issues a
system call passing that information to the kernel, which uses it to
initialize the specified event(s). The event(s) are opened and
started, and following termination of the perf command, they're
stopped. At that point, the perfmon driver will read the latest count
for the event(s), calculate the difference between the latest counter
values and previously tracked counter values, and display the final
incremental count as the event count for the cycle. An overflow
handler registered on the IDXD irq path is used to account for counter
overflows, which are signaled by an overflow interrupt.
Below are a couple of examples of perf usage for monitoring DSA events.
The following monitors all events in the 'engine' category. Becuuse
no filters are specified, this captures all engine events for the
workload, which in this case is 19 iterations of the work generated by
the kernel dmatest module.
Details describing the events can be found in Appendix D of [1],
Performance Monitoring Events, but briefly they are:
event 0x1: total input data processed, in 32-byte units
event 0x2: total data written, in 32-byte units
event 0x4: number of work descriptors that read the source
event 0x8: number of work descriptors that write the destination
event 0x10: number of work descriptors dispatched from batch descriptors
event 0x20: number of work descriptors dispatched from work queues
# perf stat -e dsa0/event=0x1,event_category=0x1/,
dsa0/event=0x2,event_category=0x1/,
dsa0/event=0x4,event_category=0x1/,
dsa0/event=0x8,event_category=0x1/,
dsa0/event=0x10,event_category=0x1/,
dsa0/event=0x20,event_category=0x1/
modprobe dmatest channel=dma0chan0 timeout=2000
iterations=19 run=1 wait=1
Performance counter stats for 'system wide':
5,332 dsa0/event=0x1,event_category=0x1/
5,327 dsa0/event=0x2,event_category=0x1/
19 dsa0/event=0x4,event_category=0x1/
19 dsa0/event=0x8,event_category=0x1/
0 dsa0/event=0x10,event_category=0x1/
19 dsa0/event=0x20,event_category=0x1/
21.977436186 seconds time elapsed
The command below illustrates filter usage with a simple example. It
specifies that MEM_MOVE operations should be counted for the DSA
device dsa0 (event 0x8 corresponds to the EV_MEM_MOVE event - Number
of Memory Move Descriptors, which is part of event category 0x3 -
Operations. The detailed category and event IDs are available in
Appendix D, Performance Monitoring Events, of [1]). In addition to
the event and event category, a number of filters are also specified
(the detailed filter values are available in Chapter 6.4 (Filter
Support) of [1]), which will restrict counting to only those events
that meet all of the filter criteria. In this case, the filters
specify that only MEM_MOVE operations that are serviced by work queue
wq0 and specifically engine number engine0 and traffic class tc0
having sizes between 0 and 4k and page size of between 0 and 1G result
in a counter hit; anything else will be filtered out and not appear in
the final count. Note that filters are optional - any filter not
specified is assumed to be all ones and will pass anything.
# perf stat -e dsa0/filter_wq=0x1,filter_tc=0x1,filter_sz=0x7,
filter_eng=0x1,event=0x8,event_category=0x3/
modprobe dmatest channel=dma0chan0 timeout=2000
iterations=19 run=1 wait=1
Performance counter stats for 'system wide':
19 dsa0/filter_wq=0x1,filter_tc=0x1,filter_sz=0x7,
filter_eng=0x1,event=0x8,event_category=0x3/
21.865914091 seconds time elapsed
The output above reflects that the unspecified workload resulted in
the counting of 19 MEM_MOVE operation events that met the filter
criteria.

s390/pci: expose a PCI device's UID as its index
On s390 each PCI device has a user-defined ID (UID) exposed under /sys/bus/pci/devices/<dev>/uid. This ID was designed to serve as the PCI device's primary index and to match the device within Linux to the device configured in the hypervisor. To serve as a primary identifier the UID must be unique within the Linux instance, this is guaranteed by the platform if and only if the UID Uniqueness Checking flag is set within the CLP List PCI Functions response. In this sense the UID serves an analogous function as the SMBIOS instance number or ACPI index exposed as the "index" respectively "acpi_index" device attributes and used by e.g. systemd to set interface names. As s390 does not use and will likely never use ACPI nor SMBIOS there is no conflict and we can just expose the UID under the "index" attribute whenever UID Uniqueness Checking is active and get systemd's interface naming support for free.

platform/x86: intel_pmc_core: export platform global reset bits via etr3 sysfs file
During PCH (platform/board) manufacturing process a global platform reset has to be induced in order for the configuration changes take the effect upon following platform reset. This is an internal platform state and is not intended to be used in the regular platform resets. The setting is exposed via ETR3 (Extended Test Mode Register 3). After the manufacturing process is completed the register cannot be written anymore and is hardware locked. This setting was commonly done by accessing PMC registers via /dev/mem but due to security concerns /dev/mem access is much more restricted, hence the reason for exposing this setting via the dedicated sysfs interface. To prevent post manufacturing abuse the register is protected by hardware locking and the file is set to read-only mode via is_visible handler. The register in MMIO space is defined for Cannon Lake and newer PCHs.

habanalabs/gaudi: add debugfs to DMA from the device
When trying to debug program, the user often needs to dump large parts of the device's DRAM, which can reach to tens of GBs. Because reading from the device's internal memory through the PCI BAR is extremely slow, the debug can take hours. Instead, we can provide the user to copy data through one of the DMA engines. This will make the operation much faster. Currently, only GAUDI is supported. In GAUDI, we need to find a PCI DMA engine that is IDLE and set the DMA as secured to be able to bypass our MMU as we currently don't map the temporary buffer to the MMU. Example bash one-line to dump entire HBM to file (~2 minutes): for (( i=0x0; i < 0x800000000; i+=0x8000000 )); do \ printf '0x%x\n' $i | sudo tee /sys/kernel/debug/habanalabs/hl0/addr ; \ echo 0x8000000 | sudo tee /sys/kernel/debug/habanalabs/hl0/dma_size ; \ sudo cat /sys/kernel/debug/habanalabs/hl0/data_dma >> hbm.txt ; done Signed-off-by: Oded Gabbay <ogabbay@kernel.org> |

power: supply: Add battery driver for Surface Aggregator Module
On newer Microsoft Surface models (specifically 7th-generation, i.e. Surface Pro 7, Surface Book 3, Surface Laptop 3, and Surface Laptop Go), battery and AC status/information is no longer handled via standard ACPI devices, but instead directly via the Surface System Aggregator Module (SSAM), i.e. the embedded controller on those devices. While on previous generation models, battery status is also handled via SSAM, an ACPI shim was present to translate the standard ACPI battery interface to SSAM requests. The SSAM interface itself, which is modeled closely after the ACPI interface, has not changed. This commit introduces a new SSAM client device driver to support battery status/information via the aforementioned interface on said Surface models. It is in parts based on the standard ACPI battery driver. Signed-off-by: Maximilian Luz <luzmaximilian@gmail.com> Signed-off-by: Sebastian Reichel <sebastian.reichel@collabora.com> |

PCI/IOV: Add sysfs MSI-X vector assignment interface
A typical cloud provider SR-IOV use case is to create many VFs for use by guest VMs. The VFs may not be assigned to a VM until a customer requests a VM of a certain size, e.g., number of CPUs. A VF may need MSI-X vectors proportional to the number of CPUs in the VM, but there is no standard way to change the number of MSI-X vectors supported by a VF. Some Mellanox ConnectX devices support dynamic assignment of MSI-X vectors to SR-IOV VFs. This can be done by the PF driver after VFs are enabled, and it can be done without affecting VFs that are already in use. The hardware supports a limited pool of MSI-X vectors that can be assigned to the PF or to individual VFs. This is device-specific behavior that requires support in the PF driver. Add a read-only "sriov_vf_total_msix" sysfs file for the PF and a writable "sriov_vf_msix_count" file for each VF. Management software may use these to learn how many MSI-X vectors are available and to dynamically assign them to VFs before the VFs are passed through to a VM. If the PF driver implements the ->sriov_get_vf_total_msix() callback, "sriov_vf_total_msix" contains the total number of MSI-X vectors available for distribution among VFs. If no driver is bound to the VF, writing "N" to "sriov_vf_msix_count" uses the PF driver ->sriov_set_msix_vec_count() callback to assign "N" MSI-X vectors to the VF. When a VF driver subsequently reads the MSI-X Message Control register, it will see the new Table Size "N".

1st set of IIO/counter device support, features and cleanup in the 5.13 cycle
Big set in here from Alexandru Ardelean enabling multiple buffer support.
This includes providing a new directory per buffer that combines
what was previously in buffer/ and scan_elements/. Old interfaces still
in place for compatiblity.
Note immuatable branch for scmi patches to allow for some significant
rework going on in that subsystem. Merge required updating to reflect
some changes in IIO.
Late rebase to fix some wrong fixes tags due to some earlier rebases
made necessary by messing up the immutable branch.
IIO New Device Support
* adi,ad5686
- Add info to support AD5673R and AD5677R
* bosch,bmi088
- New driver supporting this accelerometer + gyroscope
* cros_ec_mkbp
- New driver for this proximity sensor that exposes a 'front'
sensor. Very simple switch like device, but driver allows it
to share interface with more sophisticated proximity sensors.
* iio_scmi
- New driver to support ARM SCMI protocol to expose underlying
accelerometers and gyroscopes via this firmware interface.
* st,st_magn
- Add ID for IISMDC magnetometer.
* ti,ads131e0
- New driver supporting ads131e04, ads131e06 and ads131e08 24 bit ADCs
Counter New Device Support
* IRQ or GPIO based counter
- New driver for a conceptually simple counter that uses interrupts
to perform the count.
Features
* core
- Dual buffer supprt including:
Various helpers to centralize handling of bufferer related elements.
Document existing and new IOCTLs
Register the IIO chrdev only if it can actually be used for anything.
Rework attribute group creation in the core (lots of patches)
Merge buffer/ and scan_elements/ entries into one list + maintain
backwards compatible set.
Introduce the internal logic and IOCTL to allow multiple buffers
+ access to an anon FD per buffer to actually read from it.
Tidy up tools/iio/iio_generic_buffer and switch to new interfaces.
Update ABI docs.
A few follow up fixes, unsuprising as this was a huge bit of rework.
- Move common case setting of trig->parent to the core.
- Provide an iio_read_channel_processed_scale() to avoid loss of
precision from iio_read_channel_processed() then applying integer
scale. Use it in ntc_thermistor driver in hwmon.
- Allow drivers to specify labels from elsewhere than DT. Use it for
bmc150 and kxcjk-1013 labels related to position on 2 in one tablets.
- Document label usage for proximity and accelerometer sensors.
- Some local variable renames for consistency
tools
- Add -a parameter to iio_event_monitor to allow autoenabling of events.
* acpi_als
- Add trigger support for devices that don't support notification method.
* adi,ad7124
- Allow more than 8 channels. This is a complex little device, but is
capable of supporting up to 16 channels if the share certain
configuration settings.
* hrtimer-trigger
- Support sampling frequency below 1Hz.
* mediatek,mt8195-auxadc
- Add compatible to binding docs (always also includes mt8173)

- Avoid wrong kernel-doc marking on comment blocks.
- Fix various other minor kernel-doc issues shown by W=1
* core
- Use a signed temporary for IIO_VAL_FRACTIONAL_LOG2 to avoid odd casts.
- Fix IIO_VAL_FRACTIONAL_LOG2 for values between -1.0 and 0.0
- Add unit tests for iio_format_value()
* docs
- Fix formatting/typos in iio_configfs.rst and buffers.rst
- Add documentation of index in buffers.rst
- Fix scan element description
- Avoid some issues with HTML generation from ABI docs by moving
duplicated defintions to more generic files.
- Drop reference to long dead mailing list.
* 104-quad
- Remove left over deprecated IIO counter ABI.
* adi,adi-axi-adc
- Fix wrong bit of docs.
* adi,ad5791
- Typos
* adi,ad9834
- Switch to device managed functions in probe.
* adi,adis*
- Add and use helpers for locking to reduced duplication.
* adi,adis16480
- Fix calculation of sampling frequency when using pulse per second input.
* adi,adis16475
- Calculate the IMU scaled internal sampling rate and runtime depending
on sysfs based configuration rather than getting from DT. Drop now
unnecessary property from DT bindings doc.
* cros_ec
- Fix result of a series of recent changes that means extended buffer
attributes turn up in the wrong place. Too complex to revert the
various patches unfortunately so this is a bit messy.
* fsl,mma3452

* novuton,npcm-adc
- Local lock instead of missusing mlock.
* semtech,sx9500
- Typos
* st,sensor
- typo fix
* st,spear-adc
- Local lock instead of missusing mlock.

thunderbolt: Add support for maxhopid XDomain property
USB4 inter-domain spec mandates that the compatible hosts expose a new property "maxhopid" that tells the connection manager on the other side what is the maximum supported input HopID over the connection. Since this is depend on the lane adapter the cable is connected it needs to be filled in dynamically. For this reason we take a copy of the global properties and fill then for each XDomain connection upon first connect, and then keep updating it if the generation changes as services are being added/removed. We also take advantage of this copy to fill in the hostname. We also expose this maxhopid as an attribute under each XDomain device. While there drop kernel-doc entry for property_lock which seems to be left there when the structure was originally introduced. Signed-off-by: Mika Westerberg <mika.westerberg@linux.intel.com> |

iio: documentation: Document accelerometer label use
Some 2-in-1 laptops / convertibles with 360° (yoga-style) hinges, have 2 accelerometers, 1 in their base and 1 in their display. In many cases the kernel can detect the location of each accelerometer based on e.g. information from the ACPI tables. It is important for userspace to know the location of the 2 accelerometers. Rather then adding a new sysfs-attribute for this we can relay this information to userspace by using standardized label strings for this. This mirrors how this is done for proximity sensors. This commit documents 2 new standardized label strings for this purpose: "accel-base" "accel-display" Note the "base" and "display" suffixes were chosen to match the values used for the systemd/udev hwdb.d/60-sensor.hwdb file's ACCEL_LOCATION property.

iio: documentation: Document proximity sensor label use
Add an entry to Documentation/ABI/testing/sysfs-bus-iio for the new device label sysfs-attribute support. And document the standardized labels which may be used with proximity sensors to hint userspace about the intended use of the sensor. Using labels to differentiate between the multiple proximity sensors which a modern laptop/tablet may have was discussed in this thread: https://lore.kernel.org/linux-iio/9f9b0ff6-3bf1-63c4-eb36-901cecd7c4d9@redhat.com/ As mentioned there the "proximity-wifi*" labels are already being used in this manner on some chromebooks, see e.g.: arch/arm64/boot/dts/qcom/sc7180-trogdor.dtsi arch/arm64/boot/dts/qcom/sc7180-trogdor-lte-sku.dtsi And the "proximity-palmrest" and "proximity-lap" labels are intended to be used with the lap and palmrest sensors found in recent Lenovo ThinkPad models.

drivers/base/memory: don't store phys_device in memory blocks
No need to store the value for each and every memory block, as we can easily query the value at runtime. Reshuffle the members to optimize the memory layout. Also, let's clarify what the interface once was used for and why it's legacy nowadays. "phys_device" was used on s390x in older versions of lsmem[2]/chmem[3], back when they were still part of s390x-tools. They were later replaced by the variants in linux-utils. For example, RHEL6 and RHEL7 contain lsmem/chmem from s390-utils. RHEL8 switched to versions from util-linux on s390x [4]. "phys_device" was added with sysfs support for memory hotplug in commit |

Char/Misc driver patches for 5.12-rc1
Here is the large set of char/misc/whatever driver subsystem updates for
5.12-rc1. Over time it seems like this tree is collecting more and more
tiny driver subsystems in one place, making it easier for those
maintainers, which is why this is getting larger.
Included in here are:
- coresight driver updates
- habannalabs driver updates
- virtual acrn driver addition (proper acks from the x86
maintainers)
- broadcom misc driver addition
- speakup driver updates
- soundwire driver updates
- fpga driver updates
- amba driver updates
- mei driver updates
- vfio driver updates
- greybus driver updates
- nvmeem driver updates
- phy driver updates
- mhi driver updates
- interconnect driver udpates
- fsl-mc bus driver updates
- random driver fix
- some small misc driver updates (rtsx, pvpanic, etc.)
All of these have been in linux-next for a while, with the only reported
issue being a merge conflict in include/linux/mod_devicetable.h that you
will hit in your tree due to the dfl_device_id addition from the fpga
subsystem in here. The resolution should be simple.

cxl for 5.12
Introduce an initial driver for CXL 2.0 Type-3 Memory Devices. CXL is Compute Express Link which released the 2.0 specification in November. The Linux relevant changes in CXL 2.0 are support for an OS to dynamically assign address space to memory devices, support for switches, persistent memory, and hotplug. A Type-3 Memory Device is a PCI enumerated device presenting the CXL Memory Device Class Code and implementing the CXL.mem protocol. CXL.mem allows device to advertise CPU and I/O coherent memory to the system, i.e. typical "System RAM" and "Persistent Memory" in Linux /proc/iomem terms. In addition to the CXL.mem fast path there is an administrative command hardware mailbox interface for maintenance and provisioning. It is this command interface that is the focus of the initial driver. With this driver a CXL device that is mapped by the BIOS can be administered by Linux. Linux support for CXL PMEM and dynamic CXL address space management are to be implemented post v5.12. |

Input: cros-ec-keyb - expose function row physical map to userspace
The top-row keys in a keyboard usually have dual functionalities. E.g. A function key "F1" is also an action key "Browser back". Therefore, when an application receives an action key code from a top-row key press, the application needs to know how to correlate the action key code with the function key code and do the conversion whenever necessary. Since the userpace already knows the key scanlines (row/column) associated with a received key code. Essentially, the userspace only needs a mapping between the key row/column and the matching physical location in the top row. So, enhance the cros-ec-keyb driver to create such a mapping and expose it to userspace in the form of a function_row_physmap attribute. The attribute would be a space separated ordered list of row/column codes for the keys in the function row, in a left-to-right order. The attribute will only be present when the device has a custom design for the top-row keys.

f2fs-for-5.12-rc1
We've added two major features: 1) compression level and 2) checkpoint_merge, in
this round. 1) compression level expands 'compress_algorithm' mount option to
accept parameter as format of <algorithm>:<level>, by this way, it gives a way
to allow user to do more specified config on lz4 and zstd compression level,
then f2fs compression can provide higher compress ratio. 2) checkpoint_merge
creates a kernel daemon and makes it to merge concurrent checkpoint requests as
much as possible to eliminate redundant checkpoint issues. Plus, we can
eliminate the sluggish issue caused by slow checkpoint operation when the
checkpoint is done in a process context in a cgroup having low i/o budget and
cpu shares.
Enhancement:
- add compress level for lz4 and zstd in mount option
- checkpoint_merge mount option
- deprecate f2fs_trace_io
Bug fix:
- flush data when enabling checkpoint back
- handle corner cases of mount options
- missing ACL update and lock for I_LINKABLE flag
- attach FIEMAP_EXTENT_MERGED in f2fs_fiemap
- fix potential deadlock in compression flow
- fix wrong submit_io condition
As usual, we've cleaned up many code flows and fixed minor bugs.

Staging/IIO driver patches for 5.12-rc1
Here is the "big" set of staging and IIO driver patches for 5.12-rc1. Nothing really huge in here, the number of staging tree patches has gone down for a bit, maybe there's only so much churn to happen in here at the moment. The IIO changes are: - new drivers - new DT bindings - new iio driver features with full details in the shortlog. The staging driver patches are just a lot of tiny coding style cleanups, along with some semi-larger hikey driver cleanups as those are _almost_ good enough to get out of the staging tree, but will probably have to wait until 5.13 to have happen. All of these have been in linux-next with no reported issues.

cxl/mem: Register CXL memX devices
Create the /sys/bus/cxl hierarchy to enumerate: * Memory Devices (per-endpoint control devices) * Memory Address Space Devices (platform address ranges with interleaving, performance, and persistence attributes) * Memory Regions (active provisioned memory from an address space device that is in use as System RAM or delegated to libnvdimm as Persistent Memory regions). For now, only the per-endpoint control devices are registered on the 'cxl' bus. However, going forward it will provide a mechanism to coordinate cross-device interleave.

Drivers: hv: vmbus: Add /sys/bus/vmbus/hibernation
When a Linux VM runs on Hyper-V, if the host toolstack doesn't support hibernation for the VM (this happens on old Hyper-V hosts like Windows Server 2016, or new Hyper-V hosts if the admin or user doesn't declare the hibernation intent for the VM), the VM is discouraged from trying hibernation (because the host doesn't guarantee that the VM's virtual hardware configuration will remain exactly the same across hibernation), i.e. the VM should not try to set up the swap partition/file for hibernation, etc. x86 Hyper-V uses the presence of the virtual ACPI S4 state as the indication of the host toolstack support for a VM. Currently there is no easy and reliable way for the userspace to detect the presence of the state (see https://lkml.org/lkml/2020/12/11/1097). Add /sys/bus/vmbus/hibernation for this purpose.

net: add sysfs attribute to control napi threaded mode
This patch adds a new sysfs attribute to the network device class. Said attribute provides a per-device control to enable/disable the threaded mode for all the napi instances of the given network device, without the need for a device up/down. User sets it to 1 or 0 to enable or disable threaded mode. Note: when switching between threaded and the current softirq based mode for a napi instance, it will not immediately take effect if the napi is currently being polled. The mode switch will happen for the next time napi_schedule() is called.

platform/x86: ideapad-laptop: add "always on USB charging" control support
Certain models have a so-called "always on USB charging" feature, which enables USB charging even when the computer is turned off or suspended, and which may be controlled/queried using the SALS/HALS ACPI methods. Expose this functionality via a new device attribute (usb_charging).

thunderbolt: Add support for PCIe tunneling disabled (SL5)
Recent Intel Thunderbolt firmware connection manager has support for another security level, SL5, that disables PCIe tunneling. This option can be turned on from the BIOS. When this is set the driver exposes a new security level "nopcie" to the userspace and hides the authorized attribute under connected devices. While there we also hide it when "dponly" security level is enabled since it is not really usable in that case anyway.

f2fs: add ckpt_thread_ioprio sysfs node
Added "ckpt_thread_ioprio" sysfs node to give a way to change checkpoint merge daemon's io priority. Its default value is "be,3", which means "BE" I/O class and I/O priority "3". We can select the class between "rt" and "be", and set the I/O priority within valid range of it. "," delimiter is necessary in between I/O class and priority number.

usb: typec: Provide PD Specification Revision for cable and partner
The USB Power Delivery specification Section 6.2.1.1.5 outlines revision backward compatibility requirements starting from Revision 3.0. The Port, the Cable Plug, and the Port Partner may support either revision 2 or revision 3 independently, and communication between ports, partners, and cables of different revisions are allowed under rules that the parties agree to communicate between each other using the lowest common operating revision. This may mean that Port-to-Partner operating revision comms may be different than Port-to-CablePlug operating revision comms. For example, it is possible for a R3.0 port to communicate with a R3.0 partner using R3.0 messages, while the R3.0 port (in the same session) must communicate with the R2.0 cable using R2.0 messages only. Introduce individual revision number properties for cable and port partner so that the port can track them independently.

usb: typec: Standardize PD Revision format with Type-C Revision
The Type-C Revision was in a specific BCD format "0120H" for 1.2. USB PD revision numbers follow a similar pattern with "0300H" for 3.0. Standardizes the sysfs format for usb_power_delivery_revision to align with the BCD format used for usb_typec_revision. Example values: - "2.0": USB Power Delivery Release 2.0 - "3.0": USB Power Delivery Release 3.0 - "3.1": USB Power Delivery Release 3.1 Reviewed-by: Heikki Krogerus <heikki.krogerus@linux.intel.com> Signed-off-by: Benson Leung <bleung@chromium.org> Link: https://lore.kernel.org/r/20210129061406.2680146-2-bleung@chromium.org Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org> |

ACPI: tables: introduce support for FPDT table
ACPI Firmware Performance Data Table (FPDT) provides information about firmware performance during system boot, S3 suspend and S3 resume. Have the kernel parse the FPDT table, and expose the firmware performance data to userspace as sysfs attributes under /sys/firmware/acpi/fpdt/.
