Mailbox controller & client changes for the system controller on
PolarFire SoC. The controller bits have been acked by Jassi.
Primarily the changes work around a "hardware" bug (really the system
controller's software, but it may as well be hardware as customers
cannot change it) where interrupts are not generated if a service fails.
The mailbox controller driver is tweaked to use polling, rather than
interrupt, mode and there are some changes to timeout code required in
the client driver as a result. There's some opportunistic cleanup that I
performed while doing the swap too.
Canaan:
A single fix for some randconfig issues that crop up when !mmu is

The mtk-mmsys and mutex drivers do have a dependency on MTK_CMDQ,
even though both can work with *or* without it: since CMDQ support
can be enabled either as module or as built-in, it is necessary to
add a depends rule in Kconfig, so that we disallow building both
mtk-mmsys and mtk-mutex as built-in if mtk-cmdq-helper is built as
a module, otherwise obvious linker issues appear.

Merge tag '20230407105029.2274111-4-abel.vesa@linaro.org' into drivers-for-6.4
The dedicated ICE driver was merged through a immutable tag, to make it
available to other maintainers.
This takes the already existing duplicated support in both ufs-qcom
and sdhci-msm drivers and makes it a dedicated driver that can be used
by both mentioned drivers.
The reason for this is because, staring with SM8550, the ICE IP block
is shared between UFS and SDCC, which means we need to probe a dedicated
device and share it between those two consumers.
So let's add the ICE dedicated driver as a soc driver.
Platforms that already have ICE supported, will use it as a library
as the of_qcom_ice_get will return an ICE instance created for the
consumer device. This allows the backwards compatibility with old-style
devicetree approach.
Also, add support to HW version 4.x since it works out-of-the-box with
the current driver. The 4.x HW version is found on SM8550 platform.

Preparing for better lockdep annotations for things that happen in runpm
suspend/resume path vs shrinker/reclaim in the following patches, we
need to avoid allocations that can trigger reclaim in the icc_set_bw()
path. In the RPMh case, rpmh_write_batch() already uses GFP_ATOMIC, so
it should be reasonable to use in the smd-rpm case as well.
Alternatively, 256bytes is small enough for a function that isn't called
recursively to allocate on-stack.

Since commit 8b41fc4454 ("kbuild: create modules.builtin without
Makefile.modbuiltin or tristate.conf"), MODULE_LICENSE declarations
are used to identify modules. As a consequence, uses of the macro
in non-modules will cause modprobe to misidentify their containing
object file as a module when it is not (false positives), and modprobe
might succeed rather than failing with a suitable error message.
So remove it in the files in this commit, none of which can be built as
modules.

The BWMON hardware has two sets of registers: one for the monitor itself
and one called "global". It has what seems to be some kind of a head
switch and an interrupt control register. It's usually 0x200 in size.
On fairly recent SoCs (with the starting point seemingly being moving
the OSM programming to the firmware) these two register sets are
contiguous and overlapping, like this (on sm8450):
/* notice how base.start == global_base.start+0x100 */
reg = <0x90b6400 0x300>, <0x90b6300 0x200>;
reg-names = "base", "global_base";
Which led to some confusion and the assumption that since the
"interesting" global registers begin right after global_base+0x100,
there's no need to map two separate regions and one can simply subtract
0x100 from the offsets.
This is however not the case for anything older than SDM845, as the
global region can appear in seemingly random spots on the register map.
Handle the case where the global registers are mapped separately to allow
proper functioning of BWMONv4 on MSM8998 and older. Add specific
compatibles for 845, 8280xp, 7280 and 8550 (all of which use the single
reg space scheme) to keep backwards compatibility with old DTs.

Conor Dooley <conor@kernel.org> says:
Here are some fixes for the system controller on PolarFire SoC that I
ran into while implementing support for using the system controller to
re-program the FPGA. A few are just minor bits that I fixed in passing,
but the bulk of the patchset is changes to how the mailbox figures out
if a "service" has completed.
Prior to implementing this particular functionality, the services
requested from the system controller, via its mailbox interface, always
triggered an interrupt when the system controller was finished with
the service.
Unfortunately some of the services used to validate the FPGA images
before programming them do not trigger an interrupt if they fail.
For example, the service that checks whether an FPGA image is actually
a newer version than what is already programmed, does not trigger an
interrupt, unless the image is actually newer than the one currently
programmed. If it has an earlier version, no interrupt is triggered
and a status is set in the system controller's status register to
signify the reason for the failure.
In order to differentiate between the service succeeding & the system
controller being inoperative or otherwise unable to function, I had to
switch the controller to poll a busy bit in the system controller's
registers to see if it has completed a service.
This makes sense anyway, as the interrupt corresponds to "data ready"
rather than "tx done", so I have changed the mailbox controller driver
to do that & left the interrupt solely for signalling data ready.
It just so happened that all of the services that I had worked with and
tested up to this point were "infallible" & did not set a status, so the
particular code paths were never tested.

The system controller will only deliver an interrupt if a service
succeeds. This leaves us in the unfortunate position with current code
where there is no way to differentiate between a legitimate timeout
where the service has not completed & where it has completed, but
failed.
mbox_send_message() has its own completion, and it will time out of the
system controller does not lower the busy flag. In this case, a timeout
has occurred and the error can be propagated back to the caller.
If the busy flag is lowered, but no interrupt has arrived to trigger the
rx callback, the service can be deemed to have failed. Report -EBADMSG
in this case so that callers can differentiate.

MT2701, MT2712 and MT8173 were relying on a "default" DDP I/O routing
table, describing all of the possible connections between display block
components: while this is definitely working it's suboptimal for the
actual routing description, as we may be enabling outputs and inputs
that are not needed, possibly impacting on actual DDP performance other
than slightly prolonging boot times by having to parse a table that is
bigger than needed.
Seen that all of the other supported SoCs have got their own table and
seen that a comment in mtk-mmsys.h explicitly mentions that the wanted
way is to have one table per SoC, create a new routing table that is
specifically tailored to MT8173 and, while at it, remove mentions to
said SoC from the comment in mtk-mmsys.h.

The platforms based on SDM845 SoC locks the access to EDAC registers in the
bootloader. So probing the EDAC driver will result in a crash. Hence,
disable the creation of EDAC platform device on all SDM845 devices.
The issue has been observed on Lenovo Yoga C630 and DB845c.
While at it, also sort the members of `struct qcom_llcc_config` to avoid
any holes in-between.

Not all Qcom platforms support IRQ mode for ECC handling. For those
platforms, the current EDAC driver will not be probed due to missing ECC
IRQ in devicetree.
So add support for polling mode so that the EDAC driver can be used on all
Qcom platforms supporting LLCC.
The polling delay of 5000ms is chosen based on Qcom downstream/vendor
driver.

The Qualcomm LLCC/EDAC drivers were using a fixed register stride for
accessing the (Control and Status Registers) CSRs of each LLCC bank.
This stride only works for some SoCs like SDM845 for which driver
support was initially added.
But the later SoCs use different register stride that vary between the
banks with holes in-between. So it is not possible to use a single register
stride for accessing the CSRs of each bank. By doing so could result in a
crash.
For fixing this issue, let's obtain the base address of each LLCC bank from
devicetree and get rid of the fixed stride. This also means, there is no
need to rely on reg-names property and the base addresses can be obtained
using the index.
First index is LLCC bank 0 and last index is LLCC broadcast. If the SoC
supports more than one bank, then those need to be defined in devicetree
for index from 1..N-1.

This is a rarely used feature that has nothing to do with the
client-side of_gpio.h.
Split it out with a separate header file and Kconfig option
so it can be removed on its own timeline aside from removing
the of_gpio consumer interfaces.

The QMC (QUICC Multichannel Controller) emulates up to 64
channels within one serial controller using the same TDM
physical interface routed from the TSA.
It is available in some PowerQUICC SoC such as the
MPC885 or MPC866.
It is also available on some Quicc Engine SoCs.
This current version support CPM1 SoCs only and some

As usual, there are lots of minor driver changes across SoC platforms
from NXP, Amlogic, AMD Zynq, Mediatek, Qualcomm, Apple and Samsung.
These usually add support for additional chip variations in existing
drivers, but also add features or bugfixes.
The SCMI firmware subsystem gains a unified raw userspace interface
through debugfs, which can be used for validation purposes.
Newly added drivers include:
- New power management drivers for StarFive JH7110, Allwinner D1 and
Renesas RZ/V2M
- A driver for Qualcomm battery and power supply status
- A SoC device driver for identifying Nuvoton WPCM450 chips
- A regulator coupler driver for Mediatek MT81xxv

Here is the large set of driver core changes for 6.3-rc1.
There's a lot of changes this development cycle, most of the work falls
into two different categories:
- fw_devlink fixes and updates. This has gone through numerous review
cycles and lots of review and testing by lots of different devices.
Hopefully all should be good now, and Saravana will be keeping a
watch for any potential regression on odd embedded systems.
- driver core changes to work to make struct bus_type able to be moved
into read-only memory (i.e. const) The recent work with Rust has
pointed out a number of areas in the driver core where we are
passing around and working with structures that really do not have
to be dynamic at all, and they should be able to be read-only making
things safer overall. This is the contuation of that work (started
last release with kobject changes) in moving struct bus_type to be
constant. We didn't quite make it for this release, but the
remaining patches will be finished up for the release after this
one, but the groundwork has been laid for this effort.
Other than that we have in here:
- debugfs memory leak fixes in some subsystems
- error path cleanups and fixes for some never-able-to-be-hit
codepaths.
- cacheinfo rework and fixes
- Other tiny fixes, full details are in the shortlog
All of these have been in linux-next for a while with no reported
problems.

Core
----
- Add dedicated kmem_cache for typical/small skb->head, avoid having
to access struct page at kfree time, and improve memory use.
- Introduce sysctl to set default RPS configuration for new netdevs.
- Define Netlink protocol specification format which can be used
to describe messages used by each family and auto-generate parsers.
Add tools for generating kernel data structures and uAPI headers.
- Expose all net/core sysctls inside netns.
- Remove 4s sleep in netpoll if carrier is instantly detected on boot.
- Add configurable limit of MDB entries per port, and port-vlan.
- Continue populating drop reasons throughout the stack.
- Retire a handful of legacy Qdiscs and classifiers.
Protocols
---------
- Support IPv4 big TCP (TSO frames larger than 64kB).
- Add IP_LOCAL_PORT_RANGE socket option, to control local port range
on socket by socket basis.
- Track and report in procfs number of MPTCP sockets used.
- Support mixing IPv4 and IPv6 flows in the in-kernel MPTCP
path manager.
- IPv6: don't check net.ipv6.route.max_size and rely on garbage
collection to free memory (similarly to IPv4).
- Support Penultimate Segment Pop (PSP) flavor in SRv6 (RFC8986).
- ICMP: add per-rate limit counters.
- Add support for user scanning requests in ieee802154.
- Remove static WEP support.
- Support minimal Wi-Fi 7 Extremely High Throughput (EHT) rate
reporting.
- WiFi 7 EHT channel puncturing support (client & AP).
BPF
---
- Add a rbtree data structure following the "next-gen data structure"
precedent set by recently added linked list, that is, by using
kfunc + kptr instead of adding a new BPF map type.
- Expose XDP hints via kfuncs with initial support for RX hash and
timestamp metadata.
- Add BPF_F_NO_TUNNEL_KEY extension to bpf_skb_set_tunnel_key
to better support decap on GRE tunnel devices not operating
in collect metadata.
- Improve x86 JIT's codegen for PROBE_MEM runtime error checks.
- Remove the need for trace_printk_lock for bpf_trace_printk
and bpf_trace_vprintk helpers.
- Extend libbpf's bpf_tracing.h support for tracing arguments of
kprobes/uprobes and syscall as a special case.
- Significantly reduce the search time for module symbols
by livepatch and BPF.
- Enable cpumasks to be used as kptrs, which is useful for tracing
programs tracking which tasks end up running on which CPUs in
different time intervals.
- Add support for BPF trampoline on s390x and riscv64.
- Add capability to export the XDP features supported by the NIC.
- Add __bpf_kfunc tag for marking kernel functions as kfuncs.
- Add cgroup.memory=nobpf kernel parameter option to disable BPF
memory accounting for container environments.
Netfilter
---------
- Remove the CLUSTERIP target. It has been marked as obsolete
for years, and we still have WARN splats wrt. races of
the out-of-band /proc interface installed by this target.
- Add 'destroy' commands to nf_tables. They are identical to
the existing 'delete' commands, but do not return an error if
the referenced object (set, chain, rule...) did not exist.
Driver API
----------
- Improve cpumask_local_spread() locality to help NICs set the right
IRQ affinity on AMD platforms.
- Separate C22 and C45 MDIO bus transactions more clearly.
- Introduce new DCB table to control DSCP rewrite on egress.
- Support configuration of Physical Layer Collision Avoidance (PLCA)
Reconciliation Sublayer (RS) (802.3cg-2019). Modern version of
shared medium Ethernet.
- Support for MAC Merge layer (IEEE 802.3-2018 clause 99). Allowing
preemption of low priority frames by high priority frames.
- Add support for controlling MACSec offload using netlink SET.
- Rework devlink instance refcounts to allow registration and
de-registration under the instance lock. Split the code into multiple
files, drop some of the unnecessarily granular locks and factor out
common parts of netlink operation handling.
- Add TX frame aggregation parameters (for USB drivers).
- Add a new attr TCA_EXT_WARN_MSG to report TC (offload) warning
messages with notifications for debug.
- Allow offloading of UDP NEW connections via act_ct.
- Add support for per action HW stats in TC.
- Support hardware miss to TC action (continue processing in SW from
a specific point in the action chain).
- Warn if old Wireless Extension user space interface is used with
modern cfg80211/mac80211 drivers. Do not support Wireless Extensions
for Wi-Fi 7 devices at all. Everyone should switch to using nl80211
interface instead.
- Improve the CAN bit timing configuration. Use extack to return error
messages directly to user space, update the SJW handling, including
the definition of a new default value that will benefit CAN-FD
controllers, by increasing their oscillator tolerance.

- Track and report in procfs number of MPTCP sockets used.
- Support mixing IPv4 and IPv6 flows in the in-kernel MPTCP path
manager.
- IPv6: don't check net.ipv6.route.max_size and rely on garbage
collection to free memory (similarly to IPv4).
- Support Penultimate Segment Pop (PSP) flavor in SRv6 (RFC8986).
- ICMP: add per-rate limit counters.
- Add support for user scanning requests in ieee802154.
- Remove static WEP support.
- Support minimal Wi-Fi 7 Extremely High Throughput (EHT) rate
reporting.
- WiFi 7 EHT channel puncturing support (client & AP).
BPF:
- Add a rbtree data structure following the "next-gen data structure"
precedent set by recently added linked list, that is, by using
kfunc + kptr instead of adding a new BPF map type.
- Expose XDP hints via kfuncs with initial support for RX hash and
timestamp metadata.
- Add BPF_F_NO_TUNNEL_KEY extension to bpf_skb_set_tunnel_key to
better support decap on GRE tunnel devices not operating in collect
metadata.
- Improve x86 JIT's codegen for PROBE_MEM runtime error checks.
- Remove the need for trace_printk_lock for bpf_trace_printk and
bpf_trace_vprintk helpers.
- Extend libbpf's bpf_tracing.h support for tracing arguments of
kprobes/uprobes and syscall as a special case.
- Significantly reduce the search time for module symbols by
livepatch and BPF.
- Enable cpumasks to be used as kptrs, which is useful for tracing
programs tracking which tasks end up running on which CPUs in
different time intervals.
- Add support for BPF trampoline on s390x and riscv64.
- Add capability to export the XDP features supported by the NIC.
- Add __bpf_kfunc tag for marking kernel functions as kfuncs.
- Add cgroup.memory=nobpf kernel parameter option to disable BPF
memory accounting for container environments.
Netfilter:
- Remove the CLUSTERIP target. It has been marked as obsolete for
years, and we still have WARN splats wrt races of the out-of-band
/proc interface installed by this target.
- Add 'destroy' commands to nf_tables. They are identical to the
existing 'delete' commands, but do not return an error if the
referenced object (set, chain, rule...) did not exist.
Driver API:
- Improve cpumask_local_spread() locality to help NICs set the right
IRQ affinity on AMD platforms.
- Separate C22 and C45 MDIO bus transactions more clearly.
- Introduce new DCB table to control DSCP rewrite on egress.
- Support configuration of Physical Layer Collision Avoidance (PLCA)
Reconciliation Sublayer (RS) (802.3cg-2019). Modern version of
shared medium Ethernet.
- Support for MAC Merge layer (IEEE 802.3-2018 clause 99). Allowing
preemption of low priority frames by high priority frames.
- Add support for controlling MACSec offload using netlink SET.
- Rework devlink instance refcounts to allow registration and
de-registration under the instance lock. Split the code into
multiple files, drop some of the unnecessarily granular locks and
factor out common parts of netlink operation handling.
- Add TX frame aggregation parameters (for USB drivers).
- Add a new attr TCA_EXT_WARN_MSG to report TC (offload) warning
messages with notifications for debug.
- Allow offloading of UDP NEW connections via act_ct.
- Add support for per action HW stats in TC.
- Support hardware miss to TC action (continue processing in SW from
a specific point in the action chain).
- Warn if old Wireless Extension user space interface is used with
modern cfg80211/mac80211 drivers. Do not support Wireless
Extensions for Wi-Fi 7 devices at all. Everyone should switch to
using nl80211 interface instead.
- Improve the CAN bit timing configuration. Use extack to return
error messages directly to user space, update the SJW handling,
including the definition of a new default value that will benefit
CAN-FD controllers, by increasing their oscillator tolerance.

This is a follow-up to the deprecation of most of the old-style board
files that was merged in linux-6.0, removing them for good.
This branch is almost exclusively dead code removal based on those
annotations. Some device driver removals went through separate subsystem
trees, but the majority is in the same branch, in order to better handle
dependencies between the patches and avoid breaking bisection.
Unfortunately that leads to merge conflicts against other changes in the
subsystem trees, but they should all be trivial to resolve by removing
the files.

The register state struct is 848 bytes, which ends up bloating the
apple_rtkit_crashlog_dump_regs stack frame beyond 1024 on some
32-bit platforms, triggering compile warnings.
This doesn't matter for 64BIT/ARM64, but there's also no good reason to
copy the structure to the stack in this case. We can use __packed to
avoid alignment issues, there are no double-read hazards, and this is a
fatal error path so performance does not matter.

The qcom_scm.h file is moved into firmware/qcom, to avoid having any
Qualcomm-specific files directly in include/linux.
Support for PMIC GLINK is introduced, which on newer Qualcomm platforms
provides an interface to the firmware implementing battery management
and USB Type-C handling. Together with the base driver comes the custom
altmode support driver.
SMD RPM gains support for IPQ9574, and socinfo is extended with support
for revision 17 of the information format and soc_id for IPQ5332 and
IPQ8064 are added.
The qcom_stats is changes not to fail when not all parts are

More Qualcomm driver updates for 6.3
The qcom_scm.h file is moved into firmware/qcom, to avoid having any
Qualcomm-specific files directly in include/linux.
Support for PMIC GLINK is introduced, which on newer Qualcomm platforms
provides an interface to the firmware implementing battery management
and USB Type-C handling. Together with the base driver comes the custom
altmode support driver.
SMD RPM gains support for IPQ9574, and socinfo is extended with support
for revision 17 of the information format and soc_id for IPQ5332 and
IPQ8064 are added.
The qcom_stats is changes not to fail when not all parts are
initialized.

This introduces a new driver for the Data Capture and Compare block,
which provides a mechanism for capturing hardware state (access MMIO
registers) either upon request of triggered automatically e.g. upon a
watchdog bite, for post mortem analysis.
The remote filesystem memory share driver gains support for having its
memory bound to more than a single VMID.
The SCM driver gains the minimal support needed to support a new
mechanism where secure world can put calls on hold and later request
them to be retried.
Support for the new SA8775P platform is added to rpmhpd, QDU1000 is
added to the SCM driver and a long list of platforms are added to the
socinfo driver. Support for socinfo data revision 16 is also introduced.
Lastly a driver to program the ramp controller in MSM8976 is introduced.

Since this device is only partially initialized by the irqchip driver,
we need to mark the fwnode device as not initialized. This is to let
fw_devlink know that the device will be completely initialized at a
later point. That way, fw_devlink will continue to defer the probe of
the power domain consumers till the power domain driver successfully
binds to the struct device and completes the initialization of the
device.

The OF_POPULATED flag was set to let fw_devlink know that the device
tree node will not have a struct device created for it. This information
is used by fw_devlink to avoid deferring the probe of consumers of this
device tree node.
Let's use fwnode_dev_initialized() instead because it achieves the same
effect without using OF specific flags. This allows more generic code to
be written in driver core.

This driver relies on SMEM to populate items for each subsystem before
the device probes. The items in SMEM that are being looked for are
populated by the subsystems lazily, and therefore may not exist until
the device has booted. For example, if I build this driver into the
kernel on Trogdor Lazor and boot up, I don't see a 'modem' debugfs file
populated, because the modem boots and populates the SMEM item after
this driver probes.
Always populate the files for the subsystems if they're in SMEM, and
make the qcom_subsystem_sleep_stats_show() function return 0 if the SMEM
items still isn't there. This way we can run a simple command like
grep ^ /sys/kernel/debug/qcom_stats/*
and collect the subsystem sleep stats without interspersed errors or
missing details entirely because this driver probed first.

messages, which are sent by the firmware to notify the host OS about
state updates and HPD interrupts.
The pmic_glink_altmode driver registers for these notifications and
propagates the notifications as typec_mux, typec_switch and DRM OOB
notifications as necessary to implement DisplayPort altmode support.

The PMIC GLINK service runs on one of the co-processors of some modern
Qualcomm platforms and implements USB-C and battery managements. It uses
a message based protocol over GLINK for communication with the OS, hence
the name.
The driver implemented provides the rpmsg device for communication and
uses auxiliary bus to spawn off individual devices in respective
subsystem. The auxiliary devices are spawned off from a
platform_device, so that the drm_bridge is available early, to allow the
DisplayPort driver to probe even before the remoteproc has spun up.

Merge tag 'v6.2-next-soc' of https://git.kernel.org/pub/scm/linux/kernel/git/matthias.bgg/linux into soc/drivers
Introduce MediaTek regulator coupler driver to ensure that the SRAM
voltage in par with the GPU voltage. This allows for a stable use of the
GPU.
mtk-mutex:
- add support for MT8188 vdosys0 path
- allow it to be build as module
- add support for MT8195 vdosys1 path
mmsys:
- add MT8188 vdosys0 path
- allow to be build as a module
- add MT8195 vdosys1 path
- add support for CMDQ
- allow for up to 64 reset bits
- add supprot for the MT8195 vppsys[0,1] pathes
pm-domains:
- keep power for the MT8186 ADSP on by default
- add support for MT8188
- add support for buck isolation needed in specific pm-domains for
MT8188 and MT8192
mtk-svs:
- enable IRQ later to allow using kexec
- several improvments on the code base
- fix modalias
pmic wrapper:
- convert binding to yaml. As this is thightly coupled to the MT6357
PMIC, I took patches regarding it as well.

svs_init01() calls pm_runtime_get_sync() and added fail path as
svs_init01_finish to put usage_counter. However, pm_runtime_get_sync()
will increment usage_counter even it failed. Fix it by replacing it with
pm_runtime_resume_and_get() to keep usage counter balanced.

When the coprocessor crashes, it's useful to get a proper register dump
so we can find out what the firmware was doing. Add a decoder for this.
Originally this had ESR decoding by reusing the ARM64 arch header for
this, but that introduces some module linking and cross-arch compilation
issues, so let's leave that out for now.

Selecting CONFIG_PM_GENERIC_DOMAINS without CONFIG_PM leads to a

Unfortunately platforms are inconsistent between using 'select PM'
and 'depends on PM' here. CONFIG_PM is a user-visible symbol, so
in principle we should be using 'depends on', but on the other hand
using 'select' here is more common among drivers/soc. Go with the
majority for now, as this has a smaller risk of introducing circular
dependencies. We may need to clean this up for consistency later.

RISC-V SoC drivers for v6.3-mw0
It's all StarFive stuff this time:
Their new JH7110 SoC uses a SiFive core complex, and therefore a
SiFive cache controller too. That needed a compatible added to both the
binding and driver.
The JH7110 also has power domains, which are supported by a new driver
and a corresponding dt-binding.

This driver currently deals with GPU-SRAM regulator coupling, ensuring
that the SRAM voltage is always between a specific range of distance to
the GPU voltage, depending on the SoC, necessary in order to achieve
system stability across the full range of supported GPU frequencies.

The PPU contains a series of identical MMIO register ranges, one for
each power domain. Each range contains control/status bits for a clock
gate, reset line, output gates, and a power switch. (The clock and reset
are separate from, and in addition to, the bits in the CCU.) It also
contains a hardware power sequence engine to control the other bits.

Add cmdq support for mtk-mmsys config API.
The mmsys config register settings need to take effect with the other
HW settings(like OVL_ADAPTOR...) at the same vblanking time.
If we use CPU to write the mmsys reg, we can't guarantee all the
settings can be written in the same vblanking time.
Cmdq is used for this purpose. We prepare all the related HW settings
in one cmdq packet. The first command in the packet is "wait stream done",
and then following with all the HW settings. After the cmdq packet is
flush to GCE HW. The GCE waits for the "stream done event" to coming
and then starts flushing all the HW settings. This can guarantee all
the settings flush in the same vblanking.

The DCC is a DMA Engine designed to capture and store data
during system crash or software triggers. The DCC operates
based on user inputs via the debugfs interface. The user gives
addresses as inputs and these addresses are stored in the
dcc sram. In case of a system crash or a manual software
trigger by the user through the debugfs interface,
the dcc captures and stores the values at these addresses.
This patch contains the driver which has all the methods
pertaining to the debugfs interface, auxiliary functions to
support all the four fundamental operations of dcc namely
read, write, read/modify/write and loop. The probe method
here instantiates all the resources necessary for dcc to
operate mainly the dedicated dcc sram where it stores the
values. The DCC driver can be used for debugging purposes
without going for a reboot since it can perform software
triggers as well based on user inputs.
Also add the documentation for debugfs entries which explains
the functionalities of each debugfs file that has been created
for dcc.
The following is the justification of using debugfs interface
over the other alternatives like sysfs/ioctls
i) As can be seen from the debugfs attribute descriptions,
some of the debugfs attribute files here contains multiple
arguments which needs to be accepted from the user. This goes
against the design style of sysfs.
ii) The user input patterns have been made simple and convenient
in this case with the use of debugfs interface as user doesn't
need to shuffle between different files to execute one instruction
as was the case on using other alternatives.

- Core:
The bulk is the rework of the MSI subsystem to support per device MSI
interrupt domains. This solves conceptual problems of the current
PCI/MSI design which are in the way of providing support for PCI/MSI[-X]
and the upcoming PCI/IMS mechanism on the same device.
IMS (Interrupt Message Store] is a new specification which allows device
manufactures to provide implementation defined storage for MSI messages
contrary to the uniform and specification defined storage mechanisms for
PCI/MSI and PCI/MSI-X. IMS not only allows to overcome the size limitations
of the MSI-X table, but also gives the device manufacturer the freedom to
store the message in arbitrary places, even in host memory which is shared
with the device.
There have been several attempts to glue this into the current MSI code,
but after lengthy discussions it turned out that there is a fundamental
design problem in the current PCI/MSI-X implementation. This needs some
historical background.
When PCI/MSI[-X] support was added around 2003, interrupt management was
completely different from what we have today in the actively developed
architectures. Interrupt management was completely architecture specific
and while there were attempts to create common infrastructure the
commonalities were rudimentary and just providing shared data structures and
interfaces so that drivers could be written in an architecture agnostic
way.
The initial PCI/MSI[-X] support obviously plugged into this model which
resulted in some basic shared infrastructure in the PCI core code for
setting up MSI descriptors, which are a pure software construct for holding
data relevant for a particular MSI interrupt, but the actual association to
Linux interrupts was completely architecture specific. This model is still
supported today to keep museum architectures and notorious stranglers
alive.
In 2013 Intel tried to add support for hot-pluggable IO/APICs to the kernel,
which was creating yet another architecture specific mechanism and resulted
in an unholy mess on top of the existing horrors of x86 interrupt handling.
The x86 interrupt management code was already an incomprehensible maze of
indirections between the CPU vector management, interrupt remapping and the
actual IO/APIC and PCI/MSI[-X] implementation.
At roughly the same time ARM struggled with the ever growing SoC specific
extensions which were glued on top of the architected GIC interrupt
controller.
This resulted in a fundamental redesign of interrupt management and
provided the today prevailing concept of hierarchical interrupt
domains. This allowed to disentangle the interactions between x86 vector
domain and interrupt remapping and also allowed ARM to handle the zoo of
SoC specific interrupt components in a sane way.
The concept of hierarchical interrupt domains aims to encapsulate the
functionality of particular IP blocks which are involved in interrupt
delivery so that they become extensible and pluggable. The X86
encapsulation looks like this:
|--- device 1
[Vector]---[Remapping]---[PCI/MSI]--|...
|--- device N
where the remapping domain is an optional component and in case that it is
not available the PCI/MSI[-X] domains have the vector domain as their
parent. This reduced the required interaction between the domains pretty
much to the initialization phase where it is obviously required to
establish the proper parent relation ship in the components of the
hierarchy.
While in most cases the model is strictly representing the chain of IP
blocks and abstracting them so they can be plugged together to form a
hierarchy, the design stopped short on PCI/MSI[-X]. Looking at the hardware
it's clear that the actual PCI/MSI[-X] interrupt controller is not a global
entity, but strict a per PCI device entity.
Here we took a short cut on the hierarchical model and went for the easy
solution of providing "global" PCI/MSI domains which was possible because
the PCI/MSI[-X] handling is uniform across the devices. This also allowed
to keep the existing PCI/MSI[-X] infrastructure mostly unchanged which in
turn made it simple to keep the existing architecture specific management
alive.
A similar problem was created in the ARM world with support for IP block
specific message storage. Instead of going all the way to stack a IP block
specific domain on top of the generic MSI domain this ended in a construct
which provides a "global" platform MSI domain which allows overriding the
irq_write_msi_msg() callback per allocation.
In course of the lengthy discussions we identified other abuse of the MSI
infrastructure in wireless drivers, NTB etc. where support for
implementation specific message storage was just mindlessly glued into the
existing infrastructure. Some of this just works by chance on particular
platforms but will fail in hard to diagnose ways when the driver is used
on platforms where the underlying MSI interrupt management code does not
expect the creative abuse.
Another shortcoming of today's PCI/MSI-X support is the inability to
allocate or free individual vectors after the initial enablement of
MSI-X. This results in an works by chance implementation of VFIO (PCI
pass-through) where interrupts on the host side are not set up upfront to
avoid resource exhaustion. They are expanded at run-time when the guest
actually tries to use them. The way how this is implemented is that the
host disables MSI-X and then re-enables it with a larger number of
vectors again. That works by chance because most device drivers set up
all interrupts before the device actually will utilize them. But that's
not universally true because some drivers allocate a large enough number
of vectors but do not utilize them until it's actually required,
e.g. for acceleration support. But at that point other interrupts of the
device might be in active use and the MSI-X disable/enable dance can
just result in losing interrupts and therefore hard to diagnose subtle
problems.
Last but not least the "global" PCI/MSI-X domain approach prevents to
utilize PCI/MSI[-X] and PCI/IMS on the same device due to the fact that IMS
is not longer providing a uniform storage and configuration model.
The solution to this is to implement the missing step and switch from
global PCI/MSI domains to per device PCI/MSI domains. The resulting
hierarchy then looks like this:
|--- [PCI/MSI] device 1
[Vector]---[Remapping]---|...
|--- [PCI/MSI] device N
which in turn allows to provide support for multiple domains per device:
|--- [PCI/MSI] device 1
|--- [PCI/IMS] device 1
[Vector]---[Remapping]---|...
|--- [PCI/MSI] device N
|--- [PCI/IMS] device N
This work converts the MSI and PCI/MSI core and the x86 interrupt
domains to the new model, provides new interfaces for post-enable
allocation/free of MSI-X interrupts and the base framework for PCI/IMS.
PCI/IMS has been verified with the work in progress IDXD driver.
There is work in progress to convert ARM over which will replace the
platform MSI train-wreck. The cleanup of VFIO, NTB and other creative
"solutions" are in the works as well.
