2021-12-27drm/i915/fbc: Remember to update FBC state even when not reallocating CFBVille Syrjälä
We mustn't forget to update our FBC state even if we don't have to reallocate the CFB. Otherwise we won't refresh our notion of what eg. the new fence or the new override CFB stride should be. Using the wrong CFB stride in particular can cause underruns and could even corrupt other stuff in stolen.

2021-12-23drm/etnaviv: consider completed fence seqno in hang checkLucas Stach
Some GPU heavy test programs manage to trigger the hangcheck quite often. If there are no other GPU users in the system and the test program exhibits a very regular structure in the commandstreams that are being submitted, we can end up with two distinct submits managing to trigger the hangcheck with the FE in a very similar address range. This leads the hangcheck to believe that the GPU is stuck, while in reality the GPU is already busy working on a different job. To avoid those spurious GPU resets, also remember and consider the last completed fence seqno in the hang check.

2021-12-23drm/i915: Use trylock instead of blocking lock for __i915_gem_free_objects.Maarten Lankhorst
Convert free_work into delayed_work, similar to ttm to allow converting the blocking lock in __i915_gem_free_objects to a trylock. Unlike ttm, the object should already be idle, as it's kept alive by a reference through struct i915_vma->active, which is dropped after all vma's are idle. Because of this, we can use a no wait by default, or when the lock is contested, we use ttm's 10 ms. The trylock should only fail when the object is sharing it's resv with other objects, and typically objects are not kept locked for a long time, so we can safely retry on failure.

https://gitlab.freedesktop.org/drm/tegra into drm-next drm/tegra: Changes for v5.17-rc1 This contains a fairly large rework that makes the buffer objects behave more according to what the DMA-BUF infrastructure expects. A buffer object cache is implemented on top of that to make certain operations such as page-flipping more efficient by avoiding needless map/unmap operations. This in turn is useful to implement asynchronous commits to support legacy cursor updates. Another fairly big addition is the NVDEC driver. This uses the updated UABI introduced in v5.15-rc1 to provide access to the video decode engines found on Tegra210 and later. This also includes some power management improvements that are useful on older devices in particular because they, together with a bunch of other changes across the kernel, allow the system to scale down frequency and voltages when mostly idle and prevent these devices from becoming excessively hot. The remainder of these changes is an assortment of cleanups and minor fixes.

2021-12-22drm/i915: Require the vm mutex for i915_vma_bind()Thomas Hellström
Protect updates of struct i915_vma flags and async binding / unbinding with the vm::mutex. This means that i915_vma_bind() needs to assert vm::mutex held. In order to make that possible drop the caching of kmap_atomic() maps around i915_vma_bind(). An alternative would be to use kmap_local() but since we block cpu unplugging during sleeps inside kmap_local() sections this may have unwanted side-effects. Particularly since we might wait for gpu while holding the vm mutex. This change may theoretically increase execbuf cpu-usage on snb, but at least on non-highmem systems that increase should be very small.

2021-12-22drm/i915: Avoid using the i915_fence_array when collecting dependenciesThomas Hellström
Since the gt migration code was using only a single fence for dependencies, these were collected in a dma_fence_array. However, it turns out that it's illegal to use some dma_fences in a dma_fence_array, in particular other dma_fence_arrays and dma_fence_chains, and this causes trouble for us moving forward. Have the gt migration code instead take a const struct i915_deps for dependencies. This means we can skip the dma_fence_array creation and instead pass the struct i915_deps instead to circumvent the problem. v2: - Make the prev_deps() function static.

2021-12-20drm/etnaviv: limit submit sizesLucas Stach
Currently we allow rediculous amounts of kernel memory being allocated via the etnaviv GEM_SUBMIT ioctl, which is a pretty easy DoS vector. Put some reasonable limits in to fix this. The commandstream size is limited to 64KB, which was already a soft limit on older kernels after which the kernel only took submits on a best effort base, so there is no userspace that tries to submit commandstreams larger than this. Even if the whole commandstream is a single incrementing address load, the size limit also limits the number of potential relocs and referenced buffers to slightly under 64K, so use the same limit for those arguments. The performance monitoring infrastructure currently supports less than 50 performance counter signals, so limiting them to 128 on a single submit seems like a reasonably future-proof number for now. This number can be bumped if needed without breaking the interface.

2021-12-17drm/i915: Store backpointer to GT in uncoreMichał Winiarski
We now support a per-gt uncore, yet we're not able to infer which GT we're operating upon. Let's store a backpointer for now. At this point the early initialization of the gt needs to be broken in two parts where the first is needed to assign to the gt the i915 private data pointer and the uncore. A temporary function has been made and the two parts are __intel_gt_init_early() and intel_gt_init_early(). This split will be fixed in the future with the multitile patch.

2021-12-17drm/vmwgfx: Fix possible usage of an uninitialized variableZack Rusin
vmw_user_bo_lookup can fail to lookup user buffers, especially because the buffer handles come from the userspace. The return value has to be checked before the buffers are put back. This was spotted by Dan's Smatch statick checker: drivers/gpu/drm/vmwgfx/vmwgfx_bo.c:574 vmw_user_bo_synccpu_release() error: uninitialized symbol 'vmw_bo'.

2021-12-17drm/vmwgfx: Remove unused compile optionsZack Rusin
Before the driver had screen targets support we had to disable explicit bringup of its infrastructure because it was breaking screen objects support. Since the implementation of screen targets landed there hasn't been a reason to explicitly disable it and the options were never used. Remove of all that unused code.

2021-12-17drm/vmwgfx: Remove explicit transparent hugepages supportZack Rusin
Old versions of the svga device used to export virtual vram, handling of which was optimized on top of transparent hugepages support. Only very old devices (OpenGL 2.1 support and earlier) used this code and at this point performance differences are negligible. Because the code requires very old hardware versions to run it has been largely untested and unused for a long time. Furthermore removal of the ttm hugepages support in: commit 0d979509539e ("drm/ttm: remove ttm_bo_vm_insert_huge()") broke the coherency mode in vmwgfx when running with hugepages.
