2018-12-18drm/amd/display: Skip fast cursor updates for fb changesNicholas Kazlauskas1-0/+10
[Why] The behavior of drm_atomic_helper_cleanup_planes differs depending on whether the commit was asynchronous or not. When it's called from amdgpu_dm_atomic_commit_tail during a typical atomic commit the plane state has been swapped so it calls cleanup_fb on the old plane state. However, in the asynchronous commit codepath the call to drm_atomic_helper_commit also calls dm_plane_helper_cleanup_fb after atomic_async_update has been called. Since the plane state is updated in place and has not been swapped the cleanup_fb call affects the new plane state. This results in a use after free for the given sequence: - Fast update, fb1 pin/ref, fb1 unpin/unref - Fast update, fb2 pin/ref, fb2 unpin/unref - Slow update, fb1 pin/ref, fb2 unpin/unref - Fast update, fb2 pin/ref -> use after free. bug [How] Disallow framebuffer changes in the fast path. Since this includes a NULL framebuffer, this means that only framebuffers that have been previously pin+ref at least once will be used, preventing a use after free. This has a significant throughput reduction for cursor updates where the framebuffer changes. For most desktop usage this isn't a problem, but it does introduce performance regressions for two specific IGT tests: - cursor-vs-flip-toggle - cursor-vs-flip-varying-size Fixes: 2cc751931afc ("drm/amd/display: Add fast path for cursor plane updates") Signed-off-by: Nicholas Kazlauskas <[email protected]> Reviewed-by: Andrey Grodzovsky <[email protected]> Reviewed-by: Harry Wentland <[email protected]> Signed-off-by: Alex Deucher <[email protected]>

Mostly just initial support for Turing TU104/TU106 chipsets. Support for TU102 is missing as I don't yet have HW, but it should be trivial to add in later in the merge window (in theory). It's a bit of a rough first pass that'll get improved in future releases as a finish figuring out some of the other HW changes, but it's good enough as it stands for modesetting and suspend/resume etc. Acceleration bring-up is incomplete due to NVIDIA not yet having provided FW images for me to use, though command submission and copy engines are functional already.

2018-12-12drm/amd/display: Add fast path for cursor plane updatesNicholas Kazlauskas2-2/+73
[Why] Legacy cursor plane updates from drm helpers go through the full atomic codepath. A high volume of cursor updates through this slow code path can cause subsequent page-flips to skip vblank intervals since each individual update is slow. This problem is particularly noticeable for the compton compositor. [How] A fast path for cursor plane updates is added by using DRM asynchronous commit support provided by async_check and async_update. These don't do a full state/flip_done dependency stall and they don't block other commit work. However, DC still expects itself to be single-threaded for anything that can issue register writes. Screen corruption or hangs can occur if write sequences overlap. Every call that potentially perform register writes needs to be guarded for asynchronous updates to work. The dc_lock mutex was added for this.
