2024-07-23drm/xe: Store process name and pid in xe fileMatthew Brost
An xe file can outlive the associated process as the GPU cleanup is just triggered upon file close (process kill) and completes sometime later. If the file close triggers error conditions (GPU hangs) the process cannot be safely referenced to retrieve the name and pid for debug information.

2024-07-23drm/i915/gt: Do not consider preemption during execlists_dequeue for gen8Nitin Gote
We're seeing a GPU hang issue on a CHV platform, which was caused by commit bac24f59f454 ("drm/i915/execlists: Enable coarse preemption boundaries for Gen8"). The Gen8 platform only supports timeslicing and doesn't have a preemption mechanism, as its engines do not have a preemption timer. Commit 751f82b353a6 ("drm/i915/gt: Only disable preemption on Gen8 render engines") addressed this issue only for render engines. This patch extends that fix by ensuring that preemption is not considered for all engines on Gen8 platforms. v4: - Use the correct Fixes tag (Rodrigo Vivi) - Reworded commit log (Andi Shyti) v3: - Inside need_preempt(), condition of can_preempt() is not required as simplified can_preempt() is enough.

2024-07-23drm/ttm: Allow direct reclaim to allocate local memory v2Rajneesh Bhardwaj
Limiting the allocation of higher order pages to the closest NUMA node and enabling direct memory reclaim provides not only failsafe against situations when memory becomes too much fragmented and the allocator is not able to satisfy the request from the local node but falls back to remote pages (HUGEPAGE) but also offers performance improvement. Accessing remote pages suffers due to bandwidth limitations and could be avoided if memory becomes defragmented and in most cases without using manual compaction. (/proc/sys/vm/compact_memory) Note: On certain distros such as RHEL, the proactive compaction is disabled.

2024-07-22drm/xe: Fix warning on unreachable statementLucas De Marchi
eu_type_to_str() relies on -Wswitch to warn (and -Werror) to make sure it handles all enum values. However it's perfectly legal to pass an int to that function so in the end that function may happen to return nothing. There's too much implicit knowledge about the initialization of eu_type for a compiler to notice eu_type is never assigned to anything other than those values. Trying to reproduce this issue, none of gcc-9, gcc-10 and gcc-13 triggered for me, but this was reported in a different system with gcc-10: drivers/gpu/drm/xe/xe.o: warning: objtool: xe_gt_topology_dump() falls through to next function xe_gt_topology_init() Also it was reported these warnings when building with clang: drivers/gpu/drm/xe/xe.o: warning: objtool: xe_gt_topology_dump+0x77: sibling call from callable instruction with modified stack frame drivers/gpu/drm/xe/xe.o: warning: objtool: xe_gt_topology_dump() falls through to next function xe_dss_mask_group_ffs() drivers/gpu/drm/xe/xe.o: warning: objtool: xe_gt_topology_dump+0x77: can't find jump dest instruction at .text.xe_gt_topology_dump+0xc0 Since that value is not really possible in real world, just take the simple approach and return NULL.

2024-07-22drm/panel: Avoid warnings w/ panel-simple/panel-edp at shutdownDouglas Anderson
At shutdown if you've got a _properly_ coded DRM modeset driver then you'll get these two warnings at shutdown time: Skipping disable of already disabled panel Skipping unprepare of already unprepared panel These warnings are ugly and sound concerning, but they're actually a sign of a properly working system. That's not great. We're not ready to get rid of the calls to drm_panel_disable() and drm_panel_unprepare() because we're not 100% convinced that all DRM modeset drivers are properly calling drm_atomic_helper_shutdown() or drm_helper_force_disable_all() at the right times. However, having the warning show up for correctly working systems is bad. As a bit of a workaround, add some "if" tests to try to avoid the warning on correctly working systems. Also add some comments and update the TODO items in the hopes that future developers won't be too confused by what's going on here.

2024-07-22drm/xe/tests: Add helpers for use in live testsMichal Wajdeczko
Instead of iterating over available Xe devices within a testcase, without being able to distinguish potential failures from different devices on system with many Xe devices, introduce helpers that will allow to treat each Xe device as a parameter for the testcase like: static void bar(struct kunit *test) { struct xe_device *xe = test->priv; ... } struct kunit_case foo_live_tests[] = { KUNIT_CASE_PARAM(bar, xe_pci_live_device_gen_param), {} }; struct kunit_suite foo_suite = { .name = "foo_live", .test_cases = foo_live_tests, .init = xe_kunit_helper_xe_device_live_test_init, }; Signed-off-by: Michal Wajdeczko <michal.wajdeczko@intel.com> Reviewed-by: Jonathan Cavitt <jonathan.cavitt@intel.com> Reviewed-by: Lucas De Marchi <lucas.demarchi@intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20240720142528.530-3-michal.wajdeczko@intel.com

Typically we want to preserve pointer constness when converting from one xe pointer to another, but in some rare cases, like kunit parameter conversions, we might want to discard this constness.

2024-07-22drm/i915/dp: Don't WARN on failed link-retrain modesetImre Deak
After a bad link state is detected, the sink capabilities with which the link was originally trained could have changed: for instance another sink got connected or the retraining was forced after the rate/lane count got decreased (as a fallback). In these cases the retraining modeset fails as expected also printing a debug message, so don't WARN on it.

After the previous patch link training happens always with a valid atomic state, so remove the NOTE comments and asserts which required a valid state only for DP-MST and allowed for a NULL state for DP-SST.

2024-07-22drm/i915/dp: Retrain SST links via a modeset commitImre Deak
Instead of direct calls of the link training functions, use a modeset commit to retrain a DP link in SST mode, similarly to how this is done in DP-MST mode. Originally the current way was chosen presumedly, because there wasn't a well-established way in place for the driver to do an internal (vs. userspace/kernel client) commit. Since then such internal commits became a common place (initial-, HDMI/TC link reset commit), so there is no reason to handle the DP-SST link-retraining case differently. At the end of the current sequence the HW reported a FIFO underrun - without other issues visible to users - because during retraining the link's encoder/port was disabled/re-enabled without also disabling/re-enabling the corresponding pipe/transcoder (as required by the spec); the corresponding underrun error message was suppressed as a known issue. Based on Ankit's test on DG2 the underrun error was still reported as it got detected with some (vblank) delay wrt. other platforms. Switching to a modeset commit resolves these underrun related issues.

Having two methods to wait on GT TLB invalidations is not ideal. Remove xe_gt_tlb_invalidation_wait and only use GT TLB invalidation fences. In addition to two methods being less than ideal, once GT TLB invalidations are coalesced the seqno cannot be assigned during xe_gt_tlb_invalidation_ggtt/range. Thus xe_gt_tlb_invalidation_wait would not have a seqno to wait one.

2024-07-19drm/fb-helper: Set skip_panic if the drm driver supports drm panicJocelyn Falempe
fb_info->skip_panic flag prevents fbcon from writing to the framebuffer during a kernel panic. So set it when the drm driver implements drm panic, to avoid overwriting the panic screen.
