2024-10-17i915: fix DRM_I915_GVT_KVMGT dependenciesArnd Bergmann
Depending on x86 and KVM is not enough, as the kvm helper functions that get called here are controlled by CONFIG_KVM_X86, which is disabled if both KVM_INTEL and KVM_AMD are turned off. ERROR: modpost: "kvm_write_track_remove_gfn" [drivers/gpu/drm/i915/kvmgt.ko] undefined! ERROR: modpost: "kvm_page_track_register_notifier" [drivers/gpu/drm/i915/kvmgt.ko] undefined!

Change the dependency to CONFIG_KVM_X86 instead.

2024-10-17drm/xe: forcewake debugfs open fails on xe_forcewake_get failureHimal Prasad Ghimiray
A failure in xe_force_wake_get() no longer increments the domain's refcount. Therefore, if xe_force_wake_get() fails during forcewake debugfs open, return an error. This ensures there are no valid file descriptors to close via forcewake debugfs, preventing refcount mismanagement. v3 - return xe_wakeref_t instead of int in xe_force_wake_get() v5 - return unsigned int from xe_force_wake_get() v6 - Use helper xe_force_wake_ref_has_domain() to determine the status of the call.

The function parse_lfp_panel_dtd() is called when the driver attempts to initialize the eDP connector, and it allocates memory, which is recorded in panel->vbt.lfp_vbt_mode. However, since no eDP panel is connected, the driver fails at intel_edp_init_dpcd() and follows the failure path. Unfortunately, the allocated memory is not freed in this case.

2024-10-17drm/sched: Further optimise drm_sched_entity_push_jobTvrtko Ursulin
Having removed one re-lock cycle on the entity->lock in a patch titled "drm/sched: Optimise drm_sched_entity_push_job", with only a tiny bit larger refactoring we can do the same optimisation on the rq->lock. (Currently both drm_sched_rq_add_entity() and drm_sched_rq_update_fifo_locked() take and release the same lock.) To achieve this we make drm_sched_rq_update_fifo_locked() and drm_sched_rq_add_entity() expect the rq->lock to be held. We also align drm_sched_rq_update_fifo_locked(), drm_sched_rq_add_entity() and drm_sched_rq_remove_fifo_locked() function signatures, by adding rq as a parameter to the latter. v2: * Fix after rebase of the series. * Avoid naming inconsistency between drm_sched_rq_add/remove.

It does not seem there is a need to set the current entity in FIFO mode since ot only serves as being a "cursor" in round-robin mode.

Previously it was hitting this 3 out of 1000 executions of warm reboot. After raising it to 500, 1000 warm reboot executions passed and it didn't fail. Due to the way xe_mmio_wait32() is implemented, the timeout is able to expire early when the register matches the expected value due to the wait increments starting small.

2024-10-16drm/i915/panelreplay: Panel replay workaround with VRRAnimesh Manna
Panel Replay VSC SDP not getting sent when VRR is enabled and W1 and W2 are 0. So Program Set Context Latency in TRANS_SET_CONTEXT_LATENCY register to at least a value of 1. The same is applicable for PSR1/PSR2 as well. HSD: 14015406119 v1: Initial version. v2: Update timings stored in adjusted_mode struct. [Ville] v3: Add WA in compute_config(). [Ville] v4: - Add DISPLAY_VER() check and improve code comment. [Rodrigo] - Introduce centralized intel_crtc_vblank_delay(). [Ville] v5: Move to crtc_compute_config(). [Ville] v6: Restrict DISPLAY_VER till 14. [Mitul] v7: - Corrected code-comment. [Mitul] - dev_priv local variable removed. [Jani] v8: Introduce late_compute_config() which will take care late vblank-delay adjustment.

2024-10-16drm/xe/bmg: improve cache flushing behaviourMatthew Auld
The BSpec says that EN_L3_RW_CCS_CACHE_FLUSH must be toggled on for manual global invalidation to take effect and actually flush device cache, however this also turns on flushing for things like pipecontrol, which occurs between submissions for compute/render. This sounds like massive overkill for our needs, where we already have the manual flushing on the display side with the global invalidation. Some observations on BMG: 1. Disabling l2 caching for host writes and stubbing out the driver global invalidation but keeping EN_L3_RW_CCS_CACHE_FLUSH enabled, has no impact on wb-transient-vs-display IGT, which makes sense since the pipecontrol is now flushing the device cache after the render copy. Without EN_L3_RW_CCS_CACHE_FLUSH the test then fails, which is also expected since device cache is now dirty and display engine can't see the writes. 2. Disabling EN_L3_RW_CCS_CACHE_FLUSH, but keeping the driver global invalidation also has no impact on wb-transient-vs-display. This suggests that the global invalidation still works as expected and is flushing the device cache without EN_L3_RW_CCS_CACHE_FLUSH turned on. With that drop EN_L3_RW_CCS_CACHE_FLUSH. This helps some workloads since we no longer flush the device cache between submissions as part of pipecontrol. Edit: We now also have clarification from HW side that BSpec was indeed wrong here. v2: - Rebase and update commit message.
