* Merge branch 'drm-etnaviv-next' of https://git.pengutronix.de/git/lst/linux ↵Dave Airlie2017-02-0214-123/+329
|\ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | into drm-next It includes code cleanups from Bhumika and Liviu, a significant shader performance fix and additions to the cmdstream validator from Wladimir and the addition of a cmdbuf suballocator by myself. The suballocator improves performance on all chips by reducing the CPU overhead of the kernel driver and side steps the GC3000 FE MMU flush erratum, now making the workarounds in IOVA allocation we had before unnecessary, which results in a nice cleanup of the code in that area. * 'drm-etnaviv-next' of https://git.pengutronix.de/git/lst/linux: drm/etnaviv: Remove duplicate header file include Revert "drm/etnaviv: trick drm_mm into giving out a low IOVA" drm/etnaviv: add cmdbuf suballocator drm/etnaviv: get cmdbuf physical address through the cmdbuf abstraction drm/etnaviv: wire up iova handling in new cmdbuf abstraction drm/etnaviv: move cmdbuf de-/allocation into own file drm/etnaviv: always flush MMU TLBs on map/unmap drm/etnaviv: constify etnaviv_iommu_ops structures drm/etnaviv: set up initial PULSE_EATER register drm/etnaviv: add new GC3000 sensitive states

| * drm/etnaviv: add cmdbuf suballocatorLucas Stach2017-02-027-58/+165
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There are 3 big benefits to suballocating a single big DMA buffer for command submission: 1. Avoid hammering CMA. The old way of allocating and freeing a DMA buffer for each submission was hitting some of the real slow pathes in CMA, as this allocator was not designed for a concurrent small buffers load. 2. Less TLB flushes on IOMMUv2. If a new command buffer is mapped into the GPU address space the MMU TLBs need to be flushed. By having one big buffer statically mapped to the GPU, a lot of those flushes can be avoided. 3. No funky workarounds for GC3000. The FE TLB flush on GC3000 isn't reliable. To work around that we tried to lay out the cmdbufs in the GPU address space in a way to avoid this issue. This hasn't always worked if the address space is crowded. A single statically mapped buffer avoids the erratum completely. Signed-off-by: Lucas Stach <l.stach@pengutronix.de> Reviewed-by: Christian Gmeiner <christian.gmeiner@gmail.com>

| * drm/etnaviv: always flush MMU TLBs on map/unmapLucas Stach2017-02-021-4/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This ensures that the GPU isn't able to write into already freed objects, as doing this in the IOVA reaper isn't enough, as the gem_free_object path will also cause unmaps to happen. On MMUv2 this also ensures that stale entries, which may have been prefetched into the TLB will be purged. The flush is low overhead, as it gets batched up with the next user command buffer, so this isn't incuring an overhead for each buffer map/unmap.

This ports three mostly undocumented model/revision-specific register overrides from the Vivante kernel driver. This is relevant as at least the "disable internal DFS" for revisions > 0x5420 has shown to have a huge impact on shader performance (sped up memory read performance by 7.5x and write performance by 1.5x) on an affected GPU.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The size computations done in the ioctl function use an integer. If userspace submits a request with req->cmd_nr or req->cmd_buf_nr set to INT_MAX, the integer computations overflow later, leading to potential (kernel) memory corruption. Prevent this issue by enforcing a limit on the number of submitted commands, so that we have enough headroom later for the size computations. Note that this change has no impact on the currently available users in userspace, like e.g. libdrm/exynos. While at it, also make a comment about the size computation more detailed.

For this, it removes existing atomic commit function and relevant code specific to Exynos DRM and makes atomic helper commit to be used instead. Below are changes for the use of atomic helper commit: - add atomic_commit_tail callback specific to Exynos DRM . default implemention of atomic helper doesn't mesh well with runtime PM so the device driver which supports runtime PM should call drm_atomic_helper_commit_modeset_enables function prior to drm_atomic_helper_commit_planes function call. atomic_commit_tail callback implements this call ordering. - allow plane commit only in case that CRTC device is enabled. . for this, it calls atomic_helper_commit_planes function with DRM_PLANE_COMMIT_ACTIVE_ONLY flag in atomic_commit_tail callback.
