2021-06-17drm/i915/gt: Pipelined page migrationChris Wilson
If we pipeline the PTE updates and then do the copy of those pages within a single unpreemptible command packet, we can submit the copies and leave them to be scheduled without having to synchronously wait under a global lock. In order to manage migration, we need to preallocate the page tables (and keep them pinned and available for use at any time), causing a bottleneck for migrations as all clients must contend on the limited resources. By inlining the ppGTT updates and performing the blit atomically, each client only owns the PTE while in use, and so we can reschedule individual operations however we see fit. And most importantly, we do not need to take a global lock on the shared vm, and wait until the operation is complete before releasing the lock for others to claim the PTE for themselves.

2021-06-17drm/i915: Reference objects on the ww object listThomas Hellström
Since the ww transaction endpoint easily end up far out-of-scope of the objects on the ww object list, particularly for contending lock objects, make sure we reference objects on the list so they don't disappear under us. This comes with a performance penalty so it's been debated whether this is really needed. But I think this is motivated by the fact that locking is typically difficult to get right, and whatever we can do to make it simpler for developers moving forward should be done, unless the performance impact is far too high.

2021-06-11drm/i915/ttm: Introduce a TTM i915 gem object backendThomas Hellström
Most logical place to introduce TTM buffer objects is as an i915 gem object backend. We need to add some ops to account for added functionality like delayed delete and LRU list manipulation. Initially we support only LMEM and SYSTEM memory, but SYSTEM (which in this case means evicted LMEM objects) is not visible to i915 GEM yet. The plan is to move the i915 gem system region over to the TTM system memory type in upcoming patches. We set up GPU bindings directly both from LMEM and from the system region, as there is no need to use the legacy TTM_TT memory type. We reserve that for future porting of GGTT bindings to TTM. Remove the old lmem backend.

2021-06-11drm/exynos: use pm_runtime_resume_and_get()Inki Dae
Use pm_runtime_resume_and_get() instead of pm_runtime_get_sync() to deal with usage counter. pm_runtime_get_sync() increases the usage counter even when it failed, which makes callers to forget to decrease the usage counter and resulted in reference leak. pm_runtime_resume_and_get() function decreases the usage counter when it failed internally so it can avoid the reference leak.

2021-06-09drm/amdgpu/vcn: drop gfxoff control for VCN2+Alex Deucher
Drop disabling of gfxoff during VCN use. This allows gfxoff to kick in and potentially save power if the user is not using gfx for color space conversion or scaling. VCN1.0 had a bug which prevented it from working properly with gfxoff, so we disabled it while using VCN. That said, most apps today use gfx for scaling and color space conversion rather than overlay planes so it was generally in use anyway. This was fixed on VCN2+, but since we mostly use gfx for color space conversion and scaling and rapidly powering up/down gfx can negate the advantages of gfxoff, we left gfxoff disabled. As more applications use overlay planes for color space conversion and scaling, this starts to be a win, so go ahead and leave gfxoff enabled. Note that VCN1.0 uses vcn_v1_0_idle_work_handler() and vcn_v1_0_ring_begin_use() so they are not affected by this patch.

The meaning of 'default' for the enable_guc module parameter has been updated to accurately reflect what is supported on current platforms. So start using the defaults instead of forcing everything off. Although, note that right now, the default is for everything to be off anyway. So this is not a change for current platforms.

2021-06-09drm/i915/adl_p: Same slices mask is not same Dbuf stateStanislav Lisovskiy
We currently treat same slice mask as a same DBuf state and skip updating the Dbuf slices, if we detect that. This is wrong as if we have a multi to single pipe change or vice versa, that would be treated as a same Dbuf state and thus no changes required, so we don't get Mbus updated, causing issues. Solution: check also mbus_join, in addition to slices mask.
