2024-05-29drm/i915: Fix audio component initializationImre Deak
After registering the audio component in i915_audio_component_init() the audio driver may call i915_audio_component_get_power() via the component ops. This could program AUD_FREQ_CNTRL with an uninitialized value if the latter function is called before display.audio.freq_cntrl gets initialized. The get_power() function also does a modeset which in the above case happens too early before the initialization step and triggers the "Reject display access from task" error message added by the Fixes: commit below. Fix the above issue by registering the audio component only after the initialization step.

2024-05-29drm/i915/gt: Fix CCS id's calculation for CCS mode settingAndi Shyti
The whole point of the previous fixes has been to change the CCS hardware configuration to generate only one stream available to the compute users. We did this by changing the info.engine_mask that is set during device probe, reset during the detection of the fused engines, and finally reset again when choosing the CCS mode. We can't use the engine_mask variable anymore, as with the current configuration, it imposes only one CCS no matter what the hardware configuration is. Before changing the engine_mask for the third time, save it and use it for calculating the CCS mode. After the previous changes, the user reported a performance drop to around 1/4. We have tested that the compute operations, with the current patch, have improved by the same factor.

2024-05-29drm/i915/gt: Disarm breadcrumbs if engines are already idleChris Wilson
The breadcrumbs use a GT wakeref for guarding the interrupt, but are disarmed during release of the engine wakeref. This leaves a hole where we may attach a breadcrumb just as the engine is parking (after it has parked its breadcrumbs), execute the irq worker with some signalers still attached, but never be woken again. That issue manifests itself in CI with IGT runner timeouts while tests are waiting indefinitely for release of all GT wakerefs. <6> [209.151778] i915: Running live_engine_pm_selftests/live_engine_busy_stats <7> [209.231628] i915 0000:00:02.0: [drm:intel_power_well_disable [i915]] disabling PW_5 <7> [209.231816] i915 0000:00:02.0: [drm:intel_power_well_disable [i915]] disabling PW_4 <7> [209.231944] i915 0000:00:02.0: [drm:intel_power_well_disable [i915]] disabling PW_3 <7> [209.232056] i915 0000:00:02.0: [drm:intel_power_well_disable [i915]] disabling PW_2 <7> [209.232166] i915 0000:00:02.0: [drm:intel_power_well_disable [i915]] disabling DC_off <7> [209.232270] i915 0000:00:02.0: [drm:skl_enable_dc6 [i915]] Enabling DC6 <7> [209.232368] i915 0000:00:02.0: [drm:gen9_set_dc_state.part.0 [i915]] Setting DC state from 00 to 02 <4> [299.356116] [IGT] Inactivity timeout exceeded.

2024-05-29Revert "drm/i915: Remove extra multi-gt pm-references"Janusz Krzysztofik
This reverts commit 1f33dc0c1189efb9ae19c6fc22b64dd3e26261fb. There was a patch supposed to fix an issue of illegal attempts to free a still active i915 VMA object when parking a GT believed to be idle, reported by CI on 2-GT Meteor Lake. As a solution, an extra wakeref for a Primary GT was acquired from i915_gem_do_execbuffer() -- see commit f56fe3e91787 ("drm/i915: Fix a VMA UAF for multi-gt platform"). However, that fix occurred insufficient -- the issue was still reported by CI. That wakeref was released on exit from i915_gem_do_execbuffer(), then potentially before completion of the request and deactivation of its associated VMAs. Moreover, CI reports indicated that single-GT platforms also suffered sporadically from the same race. Since that issue was fixed by another commit f3c71b2ded5c ("drm/i915/vma: Fix UAF on destroy against retire race"), the changes introduced by that insufficient fix were dropped as no longer useful. However, that series resulted in another VMA UAF scenario now being triggered in CI. <4> [260.290809] ------------[ cut here ]------------ <4> [260.290988] list_del corruption. prev->next should be ffff888118c5d990, but was ffff888118c5a510.

Commit a78027847226 ("drm/gem: Acquire reservation lock in drm_gem_{pin/unpin}()") moved locking the DRM object's dma reservation to drm_gem_pin(), but Lima's pin callback kept calling drm_gem_shmem_pin, which also tries to lock the same dma_resv, leading to a double lock situation. As was already done for Panfrost in the previous commit, fix it by replacing drm_gem_shmem_pin() with its locked variant.

2024-05-29drm/panfrost: Fix dma_resv deadlock at drm object pin timeAdrián Larumbe
When Panfrost must pin an object that is being prepared a dma-buf attachment for on behalf of another driver, the core drm gem object pinning code already takes a lock on the object's dma reservation. However, Panfrost GEM object's pinning callback would eventually try taking the lock on the same dma reservation when delegating pinning of the object onto the shmem subsystem, which led to a deadlock. This can be shown by enabling CONFIG_DEBUG_WW_MUTEX_SLOWPATH, which throws the following recursive locking situation: weston/3440 is trying to acquire lock: ffff000000e235a0 (reservation_ww_class_mutex){+.+.}-{3:3}, at: drm_gem_shmem_pin+0x34/0xb8 [drm_shmem_helper] but task is already holding lock: ffff000000e235a0 (reservation_ww_class_mutex){+.+.}-{3:3}, at: drm_gem_pin+0x2c/0x80 [drm] Fix it by replacing drm_gem_shmem_pin with its locked version, as the lock had already been taken by drm_gem_pin().

2024-05-22tracing/treewide: Remove second parameter of __assign_str()Steven Rostedt (Google)
With the rework of how the __string() handles dynamic strings where it saves off the source string in field in the helper structure[1], the assignment of that value to the trace event field is stored in the helper value and does not need to be passed in again. This means that with: __string(field, mystring) Which use to be assigned with __assign_str(field, mystring), no longer needs the second parameter and it is unused. With this, __assign_str() will now only get a single parameter. There's over 700 users of __assign_str() and because coccinelle does not handle the TRACE_EVENT() macro I ended up using the following sed script: git grep -l __assign_str | while read a ; do sed -e 's/\(__assign_str([^,]*[^ ,]\) *,[^;]*/\1)/' $a > /tmp/test-file; mv /tmp/test-file $a; done I then searched for __assign_str() that did not end with ';' as those were multi line assignments that the sed script above would fail to catch. Note, the same updates will need to be done for: __assign_str_len() __assign_rel_str() __assign_rel_str_len() I tested this with both an allmodconfig and an allyesconfig (build only for both).

2024-05-22drm/amdgpu/atomfirmware: add intergrated info v2.3 tableLi Ma
[Why] The vram width value is 0. Because the integratedsysteminfo table in VBIOS has updated to 2.3. [How] Driver needs a new intergrated info v2.3 table too.
