drm/amd/display: Fix unsafe uses of kernel mode FPU
The point of isolating code that uses kernel mode FPU in separate compilation units is to ensure that even implicit uses of, e.g., SIMD registers for spilling occur only in a context where this is permitted, i.e., from inside a kernel_fpu_begin/end block. This is important on arm64, which uses -mgeneral-regs-only to build all kernel code, with the exception of such compilation units where FP or SIMD registers are expected to be used. Given that the compiler may invent uses of FP/SIMD anywhere in such a unit, none of its code may be accessible from outside a kernel_fpu_begin/end block. This means that all callers into such compilation units must use the DC_FP start/end macros, which must not occur there themselves. For robustness, all functions with external linkage that reside there should call dc_assert_fp_enabled() to assert that the FPU context was set up correctly. Fix this for the DCN35, DCN351 and DCN36 implementations.

drm/amdgpu: Fix general protection fault in amdgpu_vm_bo_reset_state_machine
After GPU reset with VRAM loss, a general protection fault occurs during user queue restoration when accessing vm_bo->vm after spinlock release in amdgpu_vm_bo_reset_state_machine. The root cause is that vm_bo points to the last entry from the list_for_each_entry loop, but this becomes invalid after the spinlock is released. Accessing vm_bo->vm at this point leads to memory corruption. Crash log shows: [ 326.981811] Oops: general protection fault, probably for non-canonical address 0x4156415741e58ac8: 0000 [#1] SMP NOPTI [ 326.981820] CPU: 13 UID: 0 PID: 1035 Comm: kworker/13:3 Tainted: G E 6.16.0+ #25 PREEMPT(voluntary) [ 326.981826] Tainted: [E]=UNSIGNED_MODULE [ 326.981827] Hardware name: Gigabyte Technology Co., Ltd.

Additionally, clear some other registers when scaling is

drm/vmwgfx: Fix a null-ptr access in the cursor snooper
Check that the resource which is converted to a surface exists before
trying to use the cursor snooper on it.
vmw_cmd_res_check allows explicit invalid (SVGA3D_INVALID_ID) identifiers
because some svga commands accept SVGA3D_INVALID_ID to mean "no surface",
unfortunately functions that accept the actual surfaces as objects might
(and in case of the cursor snooper, do not) be able to handle null
objects. Make sure that we validate not only the identifier (via the
vmw_cmd_res_check) but also check that the actual resource exists before
trying to do something with it.
Fixes unchecked null-ptr reference in the snooping code.

drm/xe/hw_engine_group: Fix double write lock release in error path
In xe_hw_engine_group_get_mode(), a write lock is acquired before calling switch_mode(), which in turn invokes xe_hw_engine_group_suspend_faulting_lr_jobs(). On failure inside xe_hw_engine_group_suspend_faulting_lr_jobs(), the write lock is released there, and then again in xe_hw_engine_group_get_mode(), leading to a double release. Fix this by keeping both acquire and release operation in xe_hw_engine_group_get_mode(). Fixes: |

drm/xe/uapi: loosen used tracking restriction
Currently this is hidden behind perfmon_capable() since this is technically an info leak, given that this is a system wide metric. However the granularity reported here is always PAGE_SIZE aligned, which matches what the core kernel is already willing to expose to userspace if querying how many free RAM pages there are on the system, and that doesn't need any special privileges. In addition other drm drivers seem happy to expose this. The motivation here if with oneAPI where they want to use the system wide 'used' reporting here, so not the per-client fdinfo stats. This has also come up with some perf overlay applications wanting this information. Fixes: |

drm/xe/xe_late_bind_fw: Initialize uval variable in xe_late_bind_fw_num_fans()
Initialize the uval variable to 0 in xe_late_bind_fw_num_fans() to fix a potential use of uninitialized variable warning and ensure predictable behavior. The variable is passed by reference to xe_pcode_read() which should populate it on success, but initializing it to 0 provides a safe default value and follows kernel coding best practices. v2: - uval = 0 which serves as both a safe default and the fallback value when the pcode read operation fails. v3: - Handle MMIO failure (Rodrigo) - The function should probably return the error and make the uval as pointer-argument, like the pcode_read. - Change the caller of this function to propagate the error upwards if mmio failed.

drm/gpusvm, drm/xe: Fix userptr to not allow device private pages
When userptr is used on SVM-enabled VMs, a non-NULL hmm_range::dev_private_owner value might mean that hmm_range_fault() attempts to return device private pages. Either that will fail, or the userptr code will not know how to handle those. Use NULL for hmm_range::dev_private_owner to migrate such pages to system. In order to do that, move the struct drm_gpusvm::device_private_page_owner field to struct drm_gpusvm_ctx::device_private_page_owner so that it doesn't remain immutable over the drm_gpusvm lifetime. v2: - Don't conditionally compile xe_svm_devm_owner(). - Kerneldoc xe_svm_devm_owner().

drm/xe/bo: Fix an idle assertion for local bos
Before calling ttm_bo_populate() in the CPU fault path of a bo,
we assert that the bo is not being migrated. However, for
local bos we share the reservation object with other local bos
that might be in the process of being migrated. Also some VM
operations may attach USAGE_KERNEL fences to the common
reservation object and trigger false positives from the assert.
So remove the assert and instead wait for bo idle. This may
unnecessarily wait for idle in some cases but since we're
doing this wait later in the fault path anyway we might as
well do it here as well.
This fixes warnings like:

To end the constant struggle with space shortage on 32-bit conflicting with 64-bit's needs. - The 2 patch series "mm/swapfile.c and swap.h cleanup" from Chris Li cleans up some swap code. - The 7 patch series "selftests/mm: Fix false positives and skip unsupported tests" from Donet Tom fixes a few things in our selftests code. - The 7 patch series "prctl: extend PR_SET_THP_DISABLE to only provide THPs when advised" from David Hildenbrand "allows individual processes to opt-out of THP=always into THP=madvise, without affecting other workloads on the system". It's a long story - the [1/N] changelog spells out the considerations. - The 11 patch series "Add and use memdesc_flags_t" from Matthew Wilcox gets us started on the memdesc project. Please see https://kernelnewbies.org/MatthewWilcox/Memdescs and https://blogs.oracle.com/linux/post/introducing-memdesc. - The 3 patch series "Tiny optimization for large read operations" from Chi Zhiling improves the efficiency of the pagecache read path. - The 5 patch series "Better split_huge_page_test result check" from Zi Yan improves our folio splitting selftest code. - The 2 patch series "test that rmap behaves as expected" from Wei Yang adds some rmap selftests. - The 3 patch series "remove write_cache_pages()" from Christoph Hellwig removes that function and converts its two remaining callers. - The 2 patch series "selftests/mm: uffd-stress fixes" from Dev Jain fixes some UFFD selftests issues. - The 3 patch series "introduce kernel file mapped folios" from Boris Burkov introduces the concept of "kernel file pages". Using these permits btrfs to account its metadata pages to the root cgroup, rather than to the cgroups of random inappropriate tasks. - The 2 patch series "mm/pageblock: improve readability of some pageblock handling" from Wei Yang provides some readability improvements to the page allocator code. - The 11 patch series "mm/damon: support ARM32 with LPAE" from SeongJae Park teaches DAMON to understand arm32 highmem. - The 4 patch series "tools: testing: Use existing atomic.h for vma/maple tests" from Brendan Jackman performs some code cleanups and deduplication under tools/testing/. - The 2 patch series "maple_tree: Fix testing for 32bit compiles" from Liam Howlett fixes a couple of 32-bit issues in tools/testing/radix-tree.c. - The 2 patch series "kasan: unify kasan_enabled() and remove arch-specific implementations" from Sabyrzhan Tasbolatov moves KASAN arch-specific initialization code into a common arch-neutral implementation. - The 3 patch series "mm: remove zpool" from Johannes Weiner removes zspool - an indirection layer which now only redirects to a single thing (zsmalloc). - The 2 patch series "mm: task_stack: Stack handling cleanups" from Pasha Tatashin makes a couple of cleanups in the fork code. - The 37 patch series "mm: remove nth_page()" from David Hildenbrand makes rather a lot of adjustments at various nth_page() callsites, eventually permitting the removal of that undesirable helper function. - The 2 patch series "introduce kasan.write_only option in hw-tags" from Yeoreum Yun creates a KASAN read-only mode for ARM, using that architecture's memory tagging feature. It is felt that a read-only mode KASAN is suitable for use in production systems rather than debug-only. - The 3 patch series "mm: hugetlb: cleanup hugetlb folio allocation" from Kefeng Wang does some tidying in the hugetlb folio allocation code. - The 12 patch series "mm: establish const-correctness for pointer parameters" from Max Kellermann makes quite a number of the MM API functions more accurate about the constness of their arguments. This was getting in the way of subsystems (in this case CEPH) when they attempt to improving their own const/non-const accuracy. - The 7 patch series "Cleanup free_pages() misuse" from Vishal Moola fixes a number of code sites which were confused over when to use free_pages() vs __free_pages(). - The 3 patch series "Add Rust abstraction for Maple Trees" from Alice Ryhl makes the mapletree code accessible to Rust. Required by nouveau and by its forthcoming successor: the new Rust Nova driver. - The 2 patch series "selftests/mm: split_huge_page_test: split_pte_mapped_thp improvements" from David Hildenbrand adds a fix and some cleanups to the thp selftesting code. - The 14 patch series "mm, swap: introduce swap table as swap cache (phase I)" from Chris Li and Kairui Song is the first step along the path to implementing "swap tables" - a new approach to swap allocation and state tracking which is expected to yield speed and space improvements. This patchset itself yields a 5-20% performance benefit in some situations. - The 3 patch series "Some ptdesc cleanups" from Matthew Wilcox utilizes the new memdesc layer to clean up the ptdesc code a little. - The 3 patch series "Fix va_high_addr_switch.sh test failure" from Chunyu Hu fixes some issues in our 5-level pagetable selftesting code. - The 2 patch series "Minor fixes for memory allocation profiling" from Suren Baghdasaryan addresses a couple of minor issues in relatively new memory allocation profiling feature. - The 3 patch series "Small cleanups" from Matthew Wilcox has a few cleanups in preparation for more memdesc work. - The 2 patch series "mm/damon: add addr_unit for DAMON_LRU_SORT and DAMON_RECLAIM" from Quanmin Yan makes some changes to DAMON in furtherance of supporting arm highmem. - The 2 patch series "selftests/mm: Add -Wunreachable-code and fix warnings" from Muhammad Anjum adds that compiler check to selftests code and fixes the fallout, by removing dead code. - The 10 patch series "Improvements to Victim Process Thawing and OOM Reaper Traversal Order" from zhongjinji makes a number of improvements in the OOM killer: mainly thawing a more appropriate group of victim threads so they can release resources. - The 5 patch series "mm/damon: misc fixups and improvements for 6.18" from SeongJae Park is a bunch of small and unrelated fixups for DAMON. - The 7 patch series "mm/damon: define and use DAMON initialization check function" from SeongJae Park implement reliability and maintainability improvements to a recently-added bug fix. - The 2 patch series "mm/damon/stat: expose auto-tuned intervals and non-idle ages" from SeongJae Park provides additional transparency to userspace clients of the DAMON_STAT information. - The 2 patch series "Expand scope of khugepaged anonymous collapse" from Dev Jain removes some constraints on khubepaged's collapsing of anon VMAs.

linux_kselftest-kunit-6.18-rc1
- A seven patch series adds a new parameterized test features
KUnit parameterized tests currently support two primary methods for
getting parameters:
1. Defining custom logic within a generate_params() function.
2. Using the KUNIT_ARRAY_PARAM() and KUNIT_ARRAY_PARAM_DESC()
macros with a pre-defined static array and passing
the created *_gen_params() to KUNIT_CASE_PARAM().
These methods present limitations when dealing with dynamically
generated parameter arrays, or in scenarios where populating parameters
sequentially via generate_params() is inefficient or overly complex.
These limitations are fixed with a parameterized test method.
- Fixes issues in kunit build artifacts cleanup,
- Fixes parsing skipped test problem in kselftest framework,
- Enables PCI on UML without triggering WARN()
- a few other fixes and adds support for new configs such as MIPS

Pull power management updates from Rafael Wysocki:
"The majority of these are cpufreq changes, which has been a recurring
pattern for a few recent cycles.
Those changes include new hardware support (AN7583 SoC support in the
airoha cpufreq driver, ipq5424 support in the qcom-nvmem cpufreq
driver, MT8196 support in the mediatek cpufreq driver, AM62D2 support
in the ti cpufreq driver), DT bindings and Rust code updates, cleanups
of the core and governors, and multiple driver fixes and cleanups.
Beyond that, there are hibernation fixes (some remaining 6.16 cycle
fallout and an issue related to hybrid suspend in the amdgpu driver),
cleanups of the PM core code, runtime PM documentation update, cpuidle
and power capping cleanups, and tooling updates.
