2024-03-14drm/xe: Skip VMAs pin when requesting signal to the last XE_EXECJosé Roberto de Souza1-18/+23
Doing a XE_EXEC with num_batch_buffer == 0 makes signals passed as argument to be signaled when the last real XE_EXEC is completed. But to do that it was first pinning all VMAs in drm_gpuvm_exec_lock(), this patch remove this pinning as it is not required. This change also help Mesa implementing memory over-commiting recovery as it needs to unbind not needed VMAs when the whole VM can't fit in GPU memory but it can only do the unbiding when the last XE_EXEC is completed. So with this change Mesa can get the signal it want without getting out-of-memory errors.

2024-03-14drm/xe: Invalidate userptr VMA on page pin faultMatthew Brost4-16/+29
Rather than return an error to the user or ban the VM when userptr VMA page pin fails with -EFAULT, invalidate VMA mappings. This supports the UMD use case of freeing userptr while still having bindings. Now that non-faulting VMs can invalidate VMAs, drop the usm prefix for the tile_invalidated member. v2: - Fix build error (CI) v3: - Don't invalidate VMA if in fault mode, rather kill VM (Thomas) - Update commit message with tile_invalidated name chagne (Thomas) - Wait VM bookkeep slots with VM resv lock (Thomas) v4: - Move list_del_init(&userptr.repin_link) after error check (Thomas) - Assert not in fault mode (Matthew) Fixes: dd08ebf6c352 ("drm/xe: Introduce a new DRM driver for Intel GPUs") Signed-off-by: Matthew Brost <matthew.brost@intel.com> Reviewed-by: Thomas Hellström <thomas.hellstrom@linux.intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20240312183907.933835-1-matthew.brost@intel.com (cherry picked from commit 521db22a1d70dbc596a07544a738416025b1b63c) Signed-off-by: Lucas De Marchi <lucas.demarchi@intel.com>

git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm Pull power management updates from Rafael Wysocki: "From the functional perspective, the most significant change here is the addition of support for Energy Models that can be updated dynamically at run time. There is also the addition of LZ4 compression support for hibernation, the new preferred core support in amd-pstate, new platforms support in the Intel RAPL driver, new model-specific EPP handling in intel_pstate and more. Apart from that, the cpufreq default transition delay is reduced from 10 ms to 2 ms (along with some related adjustments), the system suspend statistics code undergoes a significant rework and there is a usual bunch of fixes and code cleanups all over.

git://git.kernel.org/pub/scm/linux/kernel/git/shuah/linux-kselftest Pull KUnit updates from Shuah Khan: - fix to make kunit_bus_type const - kunit tool change to Print UML command - DRM device creation helpers are now using the new kunit device creation helpers. This change resulted in DRM helpers switching from using a platform_device, to a dedicated bus and device type used by kunit. kunit devices don't set DMA mask and this caused regression on some drm tests as they can't allocate DMA buffers. Fix this problem by setting DMA masks on the kunit device during initialization. - KUnit has several macros which accept a log message, which can contain printf format specifiers. Some of these (the explicit log macros) already use the __printf() gcc attribute to ensure the format specifiers are valid, but those which could fail the test, and hence used __kunit_do_failed_assertion() behind the scenes, did not. These include: KUNIT_EXPECT_*_MSG(), KUNIT_ASSERT_*_MSG(), and KUNIT_FAIL() A nine-patch series adds the __printf() attribute, and fixes all of the issues uncovered. * tag 'linux_kselftest-kunit-6.9-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/shuah/linux-kselftest: kunit: Annotate _MSG assertion variants with gnu printf specifiers drm: tests: Fix invalid printf format specifiers in KUnit tests drm/xe/tests: Fix printf format specifiers in xe_migrate test net: test: Fix printf format specifier in skb_segment kunit test rtc: test: Fix invalid format specifier. time: test: Fix incorrect format specifier lib: memcpy_kunit: Fix an invalid format specifier in an assertion msg lib/cmdline: Fix an invalid format specifier in an assertion msg kunit: test: Log the correct filter string in executor_test kunit: Setup DMA masks on the kunit device kunit: make kunit_bus_type const kunit: Mark filter* params as rw kunit: tool: Print UML command

2024-02-29drm/xe: get rid of MAX_BINDSPaulo Zanoni1-4/+1
Mesa has been issuing a single bind operation per ioctl since xe.ko changed to GPUVA due xe.ko bug #746. If I change Mesa to try again to issue every single bind operation it can in the same ioctl, it hits the MAX_BINDS assertion when running Vulkan conformance tests. Test dEQP-VK.sparse_resources.transfer_queue.3d.rgba32i.1024_128_8 issues 960 bind operations in a single ioctl, it's the most I could find in the conformance suite. I don't see a reason to keep the MAX_BINDS restriction: it doesn't seem to be preventing any specific issue. If the number is too big for the memory allocations, then those will fail. Nothing related to num_binds seems to be using the stack. Let's just get rid of it.

2024-02-23drm/xe: Prefer struct_size over open coded arithmeticErick Archer1-1/+1
This is an effort to get rid of all multiplications from allocation functions in order to prevent integer overflows [1]. As the "q" variable is a pointer to "struct xe_exec_queue" and this structure ends in a flexible array: struct xe_exec_queue { [...] struct xe_lrc lrc[]; }; the preferred way in the kernel is to use the struct_size() helper to do the arithmetic instead of the argument "size + size * count" in the kzalloc() function. This way, the code is more readable and more safer.

Commit a0df2cc858c3 ("drm/xe/xe_bo_move: Enhance xe_bo_move trace") inadvertently reverted commit 8d038f49c1f3 ("drm/xe: Fix cast on trace variable"), breaking the build on 32bits. As noted by Ville, there's no point in converting the pointers to u64 and add casts everywhere. In fact, it's better to just use %p and let the address be hashed. Convert all the cases in xe_trace.h to use pointers.

2024-02-21drm/xe: Implement VM snapshot support for BO's and userptrMaarten Lankhorst4-4/+211
Since we cannot immediately capture the BO's and userptr, perform it in 2 stages. The immediate stage takes a reference to each BO and userptr, while a delayed worker captures the contents and then frees the reference. This is required because in signaling context, no locks can be taken, no memory can be allocated, and no waits on userspace can be performed. With the delayed worker, all of this can be performed very easily, without having to resort to hacks. Changes since v1: - Fix crash on NULL captured vm. - Use ascii85_encode to capture BO contents and save some space. - Add length to coredump output for each captured area. Changes since v2: - Dump each mapping on their own line, to simplify tooling. - Fix null pointer deref in xe_vm_snapshot_free. Changes since v3: - Don't add uninitialized value to snap->ofs. (Souza) - Use kernel types for u32 and u64. - Move snap_mutex destruction to final vm destruction. (Souza) Changes since v4: - Remove extra memset.

2024-02-21drm/xe: Add vm snapshot mutex for easily taking a vm snapshot during devcoredumpMaarten Lankhorst2-0/+13
The devcoredump is done in fence signaling context. Because of this, we cannot take any of the normal mutexes or we would invert. Normal: Take vm->lock, dma_fence_wait() Devcoredump: from dma_fence_wait() context, take vm->lock. This doesn't work, and we only care about integrity, so take the locks around additions and removals of vma's.

Add the flag XE_VM_BIND_FLAG_DUMPABLE to notify devcoredump that this mapping should be dumped. This is not hooked up, but the uapi should be ready before merging. It's likely easier to dump the contents of the bo's at devcoredump readout time, so it's better if the bos will stay unmodified after a hang. The NEEDS_CPU_MAPPING flag is removed as requirement.
