2021-06-12drm/vmwgfx: Refactor vmw_mksstat_remove_ioctl to expect pgid match with ↵Martin Krastev
vmw_mksstat_add_ioctl to authorise removal. Original vmw_mksstat_remove_ioctl expected pid to match the corresponding vmw_mksstat_add_ioctl. That made impossible en-masse removals by one pid, which is a valid use case, so pid match was discarded. Current change enforces a broader pgid match as a form of protection from arbitrary processes interrupting an ongoing mks-guest-stats.

2021-06-12drm/vmwgfx: remove code that was using physical page addressesZack Rusin
This code has been unused for a while now. When the explicit checks for whether the driver is running on top of non-coherent swiotlb have been deprecated we lost the ability to fallback to physical mappings. Instead of trying to readd a module parameter to force usage of physical addresses it's better to just force coherent TTM pages via the force_coherent module parameter making this code pointless.

2021-05-11drm/vmwgfx: Fix cpu updates of coherent multisample surfacesThomas Hellstrom
In cases where the dirty linear memory range spans multiple sample sheets in a surface, the dirty surface region is incorrectly computed. To do this correctly and in an optimized fashion we would have to compute the dirty region of each sample sheet and compute the union of those regions. But assuming that cpu writing to a multisample surface is rather a corner case than a common case, just set the dirty region to the full surface.

2021-04-14drm/vmwgfx: Make sure bo's are unpinned before putting them backZack Rusin
During cotable resize we pin the backup buffer to make sure the trylock doesn't fail. We were never unpinning the backup buffer resulting in every subsequent cotable resize trying to release a pinned bo. After we copy the old backup to the new we can release the pin. Mob's are always pinned so we just have to make sure we unpin them before releasing them.

Thomas has noticed that the lockdep was broken in vmwgfx. It was broken during the pci initialization rework. This fixes the breakage by making sure we initialize the locking code before doing anything else. This was independently spotted and fixed by Tetsuo Handa as well.

2021-04-14drm/vmwgfx: Make sure we unpin no longer needed buffersZack Rusin
We were not correctly unpinning no longer needed buffers. In particular vmw_buffer_object, which is internally often pinned on creation wasn't unpinned on destruction and none of the internal MOB buffers were unpinned before being put back. Technically this existed for a long time but commit 57fcd550eb15 ("drm/ttm: Warn on pinning without holding a reference") introduced a WARN_ON which was filling up the kernel logs rather quickly. Quite frankly internal usage of vmw_buffer_object and in general pinning needs to be refactored in vmwgfx but for now this makes it work.

2021-02-25drm: Use state helper instead of the plane state pointerMaxime Ripard
Many drivers reference the plane->state pointer in order to get the current plane state in their atomic_update or atomic_disable hooks, which would be the new plane state in the global atomic state since _swap_state happened when those hooks are run. Use the drm_atomic_get_new_plane_state helper to get that state to make it more obvious.
