2022-03-02drm/i915/xehpsdv: Move render/compute engine reset domains related workaroundsSrinivasan Shanmugam1-13/+13
Registers that exist in the shared render/compute reset domain need to be placed on an engine workaround list to ensure that they are properly re-applied whenever an RCS or CCS engine is reset. We have a number of workarounds (updating registers MLTICTXCTL, L3SQCREG1_CCS0, GEN12_MERT_MOD_CTRL, and GEN12_GAMCNTRL_CTRL) that are incorrectly implemented on the 'gt' workaround list and need to be moved accordingly.

2022-03-02drm/i915/xehp: Add compute workaroundsMatt Roper3-0/+56
Additional workarounds are required once we start exposing CCS engines. Note that we have a number of workarounds that update registers in the shared render/compute reset domain. Historically we've just added such registers to the RCS engine's workaround list. But going forward we should be more careful to place such workarounds on a wa_list for an engine that definitely exists and is not fused off (e.g., a platform with no RCS would never apply the RCS wa_list). We'll keep rcs_engine_wa_init() focused on RCS-specific workarounds that only need to be applied if the RCS engine is present. A separate general_render_compute_wa_init() function will be used to define workarounds that touch registers in the shared render/compute reset domain and that we need to apply regardless of what render and/or compute engines actually exist. Any workarounds defined in this new function will internally be added to the first present RCS or CCS engine's workaround list to ensure they get applied (and only get applied once rather than being needlessly re-applied several times).

2022-03-02drm/i915/xehp: handle fused off CCS enginesDaniele Ceraolo Spurio3-4/+42
HW resources are divided across the active CCS engines at the compute slice level, with each CCS having priority on one of the cslices. If a compute slice has no enabled DSS, its paired compute engine is not usable in full parallel execution because the other ones already fully saturate the HW, so consider it fused off. v2 (José): - moved it to its own function - fixed definition of ccs_mask v3 (Matt): - Replace fls() condition with a simple IP version test v4 (Matt): - Don't try to calculate a ccs_mask using intel_slicemask_from_dssmask() until we've determined that we're running on an Xe_HP platform where the logic makes sense (and won't overflow).

2022-03-02drm/i915/xehp: CCS should use RCS setup functionsMatt Roper6-7/+16
The compute engine handles the same commands the render engine can (except 3D pipeline), so it makes sense that CCS is more similar to RCS than non-render engines. The CCS context state (lrc) is also similar to the render one, so reuse it. Note that the compute engine has its own CTX_R_PWR_CLK_STATE register. In order to avoid having multiple RCS && CCS checks, add the following engine flag: - I915_ENGINE_HAS_RCS_REG_STATE - use the render (larger) reg state ctx.

The reset domain is shared between render and all compute engines, so resetting one will affect the others. Note: Before performing a reset on an RCS or CCS engine, the GuC will attempt to preempt-to-idle the other non-hung RCS/CCS engines to avoid impacting other clients (since some shared modules will be reset). If other engines are executing non-preemptable workloads, the impact is unavoidable and some work may be lost.

Move initialization of submission-related spinlock, lists and workers to init_early. This fixes an issue where if the GuC init fails we might still try to get the lock in the context cleanup code. Note that it is safe to call the GuC context cleanup code even if the init failed because all contexts are initialized with an invalid GuC ID, which will cause the GuC side of the cleanup to be skipped, so it is easier to just make sure the variables are initialized than to special case the cleanup to handle the case when they're not.

2022-03-01drm/i915/selftests: handle allocation failuresMatthew Auld2-2/+8
If we have to contend with non-mappable LMEM, then we need to ensure the object fits within the mappable portion, like in the selftests, where we later try to CPU access the pages. However if it can't then we need to gracefully handle this, without throwing an error. Also it looks like TTM will return -ENOMEM, in ttm_bo_mem_space() after exhausting all possible placements.

2022-02-28drm/i915: Remove redundant state verification during TypeC AUX power well disablingImre Deak1-31/+1
Commit d5ce34da31456a ("drm/i915: Add state verification for the TypeC port mode") added a verification to the TypeC AUX power well enable()/disable() hooks to check if the TypeC port related to this power well is properly locked. If the disabling happens asynchronously the verification is skipped, since in this case the port is unlocked. The detection of asnychronous disabling doesn't work as intended though, since the power well's reference count is always 0 when its disable() hook is called (and since there won't be any domain reference held for this power well either, the verification is always skipped); remove the verification from the disable() hook for now. In the power well's enable() hook the power well's reference will be always >0 and there won't be any asynchronous disabling pending for it, so we can drop the async refcount check from there. No functional change.

2022-02-28drm/i915: Clarify vma lifetimeThomas Hellström5-33/+79
It's unclear what reference the initial vma kref reference refers to. A vma can have multiple weak references, the object vma list, the vm's bound list and the GT's closed_list, and the initial vma reference can be put from lookups of all these lists. With the current implementation this means that any holder of yet another vma refcount (currently only i915_gem_object_unbind()) needs to be holding two of either *) An object refcount, *) A vm open count *) A vma open count in order for us to not risk leaking a reference by having the initial vma reference being put twice. Address this by re-introducing i915_vma_destroy() which removes all weak references of the vma and *then* puts the initial vma refcount. This makes a strong vma reference hold on to the vma unconditionally. Perhaps a better name would be i915_vma_revoke() or i915_vma_zombify(), since other callers may still hold a refcount, but with the prospect of being able to replace the vma refcount with the object lock in the near future, let's stick with i915_vma_destroy(). Finally this commit fixes a race in that previously i915_vma_release() and now i915_vma_destroy() could destroy a vma without taking the vm->mutex after an advisory check that the vma mm_node was not allocated. This would race with the ungrab_vma() function creating a trace similar to the below one. This was fixed in one of the __i915_vma_put() callsites in commit bc1922e5d349 ("drm/i915: Fix a race between vma / object destruction and unbinding") but although not seemingly triggered by CI, that is not sufficient. This patch is needed to fix that properly.
