SoC driver updates for 6.2
There are few major updates in the SoC specific drivers, mainly the usual
reworks and support for variants of the existing SoC. While this remains
Arm centric for the most part, the branch now also contains updates to
risc-v and loongarch specific code in drivers/soc/.
Notable changes include:
- Support for the newly added Qualcomm Snapdragon variants
(MSM8956, MSM8976, SM6115, SM4250, SM8150, SA8155 and SM8550) in the
soc ID, rpmh, rpm, spm and powerdomain drivers.
- Documentation for the somewhat controversial qcom,board-id
properties that are required for booting a number of machines
- A new SoC identification driver for the loongson-2 (loongarch)
platform
- memory controller updates for stm32, tegra, and renesas.
- a new DT binding to better describe LPDDR2/3/4/5 chips in
the memory controller subsystem
- Updates for Tegra specific drivers across multiple subsystems,
improving support for newer SoCs and better identification
- Minor fixes for Broadcom, Freescale, Apple, Renesas, Sifive,
TI, Mediatek and Marvell SoC drivers

PM: domains: Store the next hrtimer wakeup in genpd
The arch timer cannot wake up the Qualcomm Technologies, Inc. (QTI) SoCs from the deeper CPUidle states. To be able to wakeup from these deeper states, another always-on timer needs to be programmed through the so called CONTROL_TCS. As the RSC is part of CPU subsystem and the corresponding APSS RSC device is attached to the cluster PM domain (through genpd), it holds the responsibility to program the always-on timer, before entering any of these deeper CPUidle states. However, programming the timer requires information about the next hrtimer wakeup for the cluster PM domain, which is currently only known by genpd. Therefore, let's share this data through a new genpd helper function, dev_pm_genpd_get_next_hrtimer(). Signed-off-by: Maulik Shah <quic_mkshah@quicinc.com> Cc: "Rafael J. Wysocki" <rafael@kernel.org> [Ulf: Reworked the code and updated the commit message] Signed-off-by: Ulf Hansson <ulf.hansson@linaro.org> Tested-by: Dmitry Baryshkov <dmitry.baryshkov@linaro.org> # SM8450 Signed-off-by: Bjorn Andersson <andersson@kernel.org> Link: https://lore.kernel.org/r/20221018152837.619426-5-ulf.hansson@linaro.org |

ACPI and device properties fixes for 6.1-rc3
- Fix the documentation of the *_match_string() family of functions to
properly cover the return value (Andy Shevchenko).
- Fix a possible integer overflow during multiplication in the ACPI
PCC code (Manank Patel).
- Make the ACPI device resources code skip IRQ override on Asus
Vivobook S5602ZA (Tamim Khan).
- Add LATT2021 to the list of device IDs that are ignored when
returned by _DEP, because there are no drivers for them in the
kernel and no plans to add such drivers (Hans de Goede).

PM: domains: Fix handling of unavailable/disabled idle states
Platforms can provide the information about the availability of each
idle states via status flag. Platforms may have to disable one or more
idle states for various reasons like broken firmware or other unmet

Interrupt subsystem updates:
- Core code:
- Provide a generic wrapper which can be utilized in drivers to handle
the problem of force threaded demultiplex interrupts on RT enabled
kernels. This avoids conditionals and horrible quirks in drivers all
over the place.
- Fix up affected pinctrl and GPIO drivers to make them cleanly RT safe.
- Interrupt drivers:
- A new driver for the FSL MU platform specific MSI implementation.
- Make irqchip_init() available for pure ACPI based systems.
- Provide a functional DT binding for the Realtek RTL interrupt chip.
- The usual DT updates and small code improvements all over the place.

linux-next for a couple of months without, to my knowledge, any negative reports (or any positive ones, come to that). - Also the Maple Tree from Liam R. Howlett. An overlapping range-based tree for vmas. It it apparently slight more efficient in its own right, but is mainly targeted at enabling work to reduce mmap_lock contention. Liam has identified a number of other tree users in the kernel which could be beneficially onverted to mapletrees. Yu Zhao has identified a hard-to-hit but "easy to fix" lockdep splat (https://lkml.kernel.org/r/CAOUHufZabH85CeUN-MEMgL8gJGzJEWUrkiM58JkTbBhh-jew0Q@mail.gmail.com). This has yet to be addressed due to Liam's unfortunately timed vacation. He is now back and we'll get this fixed up. - Dmitry Vyukov introduces KMSAN: the Kernel Memory Sanitizer. It uses clang-generated instrumentation to detect used-unintialized bugs down to the single bit level. KMSAN keeps finding bugs. New ones, as well as the legacy ones. - Yang Shi adds a userspace mechanism (madvise) to induce a collapse of memory into THPs. - Zach O'Keefe has expanded Yang Shi's madvise(MADV_COLLAPSE) to support file/shmem-backed pages. - userfaultfd updates from Axel Rasmussen - zsmalloc cleanups from Alexey Romanov - cleanups from Miaohe Lin: vmscan, hugetlb_cgroup, hugetlb and memory-failure - Huang Ying adds enhancements to NUMA balancing memory tiering mode's page promotion, with a new way of detecting hot pages. - memcg updates from Shakeel Butt: charging optimizations and reduced memory consumption. - memcg cleanups from Kairui Song. - memcg fixes and cleanups from Johannes Weiner. - Vishal Moola provides more folio conversions - Zhang Yi removed ll_rw_block() :( - migration enhancements from Peter Xu - migration error-path bugfixes from Huang Ying - Aneesh Kumar added ability for a device driver to alter the memory tiering promotion paths. For optimizations by PMEM drivers, DRM drivers, etc. - vma merging improvements from Jakub Matěn. - NUMA hinting cleanups from David Hildenbrand. - xu xin added aditional userspace visibility into KSM merging activity. - THP & KSM code consolidation from Qi Zheng. - more folio work from Matthew Wilcox. - KASAN updates from Andrey Konovalov. - DAMON cleanups from Kaixu Xia. - DAMON work from SeongJae Park: fixes, cleanups. - hugetlb sysfs cleanups from Muchun Song. - Mike Kravetz fixes locking issues in hugetlbfs and in hugetlb core. -----BEGIN PGP SIGNATURE----- iHUEABYKAB0WIQTTMBEPP41GrTpTJgfdBJ7gKXxAjgUCY0HaPgAKCRDdBJ7gKXxA joPjAQDZ5LlRCMWZ1oxLP2NOTp6nm63q9PWcGnmY50FjD/dNlwEAnx7OejCLWGWf bbTuk6U2+TKgJa4X7+pbbejeoqnt5QU= =xfWx -----END PGP SIGNATURE----- Merge tag 'mm-stable-2022-10-08' of git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm Pull MM updates from Andrew Morton: - Yu Zhao's Multi-Gen LRU patches are here.

The first batch of KVM patches, mostly covering x86, which I
am sending out early due to me travelling next week. There is a lone mm patch for which Andrew gave an informal ack at https://lore.kernel.org/linux-mm/20220817102500.440c6d0a3fce296fdf91bea6@linux-foundation.org. I will send the bulk of ARM work, as well as other architectures, at the end of next week. ARM: * Account stage2 page table allocations in memory stats. x86: * Account EPT/NPT arm64 page table allocations in memory stats. * Tracepoint cleanups/fixes for nested VM-Enter and emulated MSR accesses. * Drop eVMCS controls filtering for KVM on Hyper-V, all known versions of Hyper-V now support eVMCS fields associated with features that are enumerated to the guest. * Use KVM's sanitized VMCS config as the basis for the values of nested VMX capabilities MSRs. * A myriad event/exception fixes and cleanups. Most notably, pending exceptions morph into VM-Exits earlier, as soon as the exception is queued, instead of waiting until the next vmentry. This fixed a longstanding issue where the exceptions would incorrecly become double-faults instead of triggering a vmexit; the common case of page-fault vmexits had a special workaround, but now it's fixed for good. * A handful of fixes for memory leaks in error paths. * Cleanups for VMREAD trampoline and VMX's VM-Exit assembly flow. * Never write to memory from non-sleepable kvm_vcpu_check_block() * Selftests refinements and cleanups. * Misc typo cleanups. Generic: * remove KVM_REQ_UNHALT -----BEGIN PGP SIGNATURE----- iQFIBAABCAAyFiEE8TM4V0tmI4mGbHaCv/vSX3jHroMFAmM2zwcUHHBib256aW5p QHJlZGhhdC5jb20ACgkQv/vSX3jHroNpbwf+MlVeOlzE5SBdrJ0TEnLmKUel1lSz QnZzP5+D65oD0zhCilUZHcg6G4mzZ5SdVVOvrGJvA0eXh25ruLNMF6jbaABkMLk/ FfI1ybN7A82hwJn/aXMI/sUurWv4Jteaad20JC2DytBCnsW8jUqc49gtXHS2QWy4 3uMsFdpdTAg4zdJKgEUfXBmQviweVpjjl3ziRyZZ7yaeo1oP7XZ8LaE1nR2l5m0J mfjzneNm5QAnueypOh5KhSwIvqf6WHIVm/rIHDJ1HIFbgfOU0dT27nhb1tmPwAcE +cJnnMUHjZqtCXteHkAxMClyRq0zsEoKk0OGvSOOMoq3Q0DavSXUNANOig== =/hqX -----END PGP SIGNATURE----- Merge tag 'for-linus' of git://git.kernel.org/pub/scm/virt/kvm/kvm Pull kvm updates from Paolo Bonzini: "The first batch of KVM patches, mostly covering x86.

Driver core changes for 6.1-rc1
Here is the big set of driver core and debug printk changes for 6.1-rc1.
Included in here is:
- dynamic debug updates for the core and the drm subsystem. The
drm changes have all been acked by the relevant maintainers.
- kernfs fixes for syzbot reported problems
- kernfs refactors and updates for cgroup requirements
- magic number cleanups and removals from the kernel tree (they
were not being used and they really did not actually do
anything.)
- other tiny cleanups
All of these have been in linux-next for a while with no reported
issues.

mm: hugetlb: simplify per-node sysfs creation and removal
Patch series "simplify handling of per-node sysfs creation and removal",
v4.
This patch (of 2):
The following commit offload per-node sysfs creation and removal to a
kworker and did not say why it is needed. And it also said "I don't know
that this is absolutely required". It seems like the author was not sure
as well. Since it only complicates the code, this patch will revert the
changes to simplify the code.

PM: runtime: Return -EINPROGRESS from rpm_resume() in the RPM_NOWAIT case
The prospective callers of rpm_resume() passing RPM_NOWAIT to it may be confused when it returns 0 without actually resuming the device which may happen if the device is suspending at the given time and it will only resume when the suspend in progress has completed. To avoid that confusion, return -EINPROGRESS from rpm_resume() in that case. Since none of the current callers passing RPM_NOWAIT to rpm_resume() check its return value, this change has no functional impact. Signed-off-by: Rafael J.

devcoredump : Serialize devcd_del work
In following scenario(diagram), when one thread X running dev_coredumpm()
adds devcd device to the framework which sends uevent notification to
userspace and another thread Y reads this uevent and call to
devcd_data_write() which eventually try to delete the queued timer that
is not initialized/queued yet.
So, debug object reports some warning and in the meantime, timer is
initialized and queued from X path. and from Y path, it gets reinitialized
again and timer->entry.pprev=NULL and try_to_grab_pending() stucks.
To fix this, introduce mutex and a boolean flag to serialize the behaviour.
cpu0(X) cpu1(Y)
dev_coredump() uevent sent to user space
device_add() ======================> user space process Y reads the
uevents writes to devcd fd
which results into writes to

Driver core fixes for 6.0-rc5
Here are some small driver core and debugfs fixes for 6.0-rc5.
Included in here are:
- multiple attempts to get the arch_topology code to work properly on
non-cluster SMT systems. First attempt caused build breakages in
linux-next and 0-day, second try worked.
- debugfs fixes for a long-suffering memory leak. The pattern of
debugfs_remove(debugfs_lookup(...)) turns out to leak dentries, so
add debugfs_lookup_and_remove() to fix this problem. Also fix up
the scheduler debug code that highlighted this problem. Fixes for
other subsystems will be trickling in over the next few months for
this same issue once the debugfs function is merged.
All of these have been in linux-next since Wednesday with no reported
problems.

arch_topology: Make cluster topology span at least SMT CPUs
Currently cpu_clustergroup_mask() will return CPU mask if cluster span more
or the same CPUs as cpu_coregroup_mask(). This will result topology borken
on non-Cluster SMT machines when building with CONFIG_SCHED_CLUSTER=y.
Test with:
qemu-system-aarch64 -enable-kvm -machine virt \
-net none \
-cpu host \
-bios ./QEMU_EFI.fd \
-m 2G \
-smp 48,sockets=2,cores=12,threads=2 \
-kernel $Image \
-initrd $Rootfs \
-nographic
-append "rdinit=init console=ttyAMA0 sched_verbose loglevel=8"
We'll get below error:
[ 3.084568] BUG: arch topology borken
[ 3.084570] the SMT domain not a subset of the CLS domain
Since cluster is a level higher than SMT, fix this by making cluster
spans at least SMT CPUs.

regmap: trace: Remove useless check for NULL for bulk ops
If the buffer pointer is NULL we already are in troubles since regmap bulk API expects caller to provide valid parameters, it dereferences that without any checks before we call for traces. Moreover, the current code will print garbage in the case of buffer is NULL and length is not 0.

arch_topology: Make cluster topology span at least SMT CPUs
Currently cpu_clustergroup_mask() will return CPU mask if cluster span more
or the same CPUs as cpu_coregroup_mask(). This will result topology borken
on non-Cluster SMT machines when building with CONFIG_SCHED_CLUSTER=y.
Test with:
qemu-system-aarch64 -enable-kvm -machine virt \
-net none \
-cpu host \
-bios ./QEMU_EFI.fd \
-m 2G \
-smp 48,sockets=2,cores=12,threads=2 \
-kernel $Image \
-initrd $Rootfs \
-nographic \
-append "rdinit=init console=ttyAMA0 sched_verbose loglevel=8"
We'll get below error:
[ 3.084568] BUG: arch topology borken
[ 3.084570] the SMT domain not a subset of the CLS domain
Since cluster is a level higher than SMT, fix this by making cluster
spans at least SMT CPUs.

devres: Slightly optimize alloc_dr()
If the gfp flag used for the memory allocation already has __GFP_ZERO, then there is no need to explicitly clear the "struct devres_node". It is already zeroed. This saves a few cycles when using devm_zalloc() and co. In the case of devres_alloc() (which calls __devres_alloc_node()), the compiler could remove the test and the memset() because it should be able to see that the __GFP_ZERO flag is set. So this would make the code both faster and smaller.

firmware_loader: Fix memory leak in firmware upload
In the case of firmware-upload, an instance of struct fw_upload is
allocated in firmware_upload_register(). This data needs to be freed
in fw_dev_release(). Create a new fw_upload_free() function in
sysfs_upload.c to handle the firmware-upload specific memory frees
and incorporate the missing kfree call for the fw_upload structure.

firmware_loader: Fix use-after-free during unregister
In the following code within firmware_upload_unregister(), the call to
device_unregister() could result in the dev_release function freeing the
fw_upload_priv structure before it is dereferenced for the call to
module_put(). This bug was found by the kernel test robot using
CONFIG_KASAN while running the firmware selftests.
device_unregister(&fw_sysfs->dev);
module_put(fw_upload_priv->module);
The problem is fixed by copying fw_upload_priv->module to a local variable
for use when calling device_unregister().

Early cacheinfo failed, ret = -2
Treat -ENOENT specifically to silence this error since it means that the
platform does not support reporting its cache information.
