Don't use a per-master semaphore (ttm lock) for reservation protection, but rather a per-device semaphore. This is needed since clients connecting using render nodes aren't master aware. The ttm lock used should probably be replaced with a reader-write semaphore once the function down_xx_interruptible() is available.

When a context is first referenced in the command stream, make sure that all scrubbed (as a result of eviction) bindings are re-emitted. Also make sure that all bound resources are put on the resource validate list. This is needed for legacy emulation, since legacy user-space drivers will typically not re-emit shader bindings. It also removes the requirement for user-space drivers to re-emit render-target- and texture bindings. Makes suspend and hibernate now also work with legacy user-space drivers on guest-backed devices. v2: Don't rebind on legacy devices.

Also request kernel ttm_buffer objects for buffer objects that obviously aren't visible to user-space, and save some device address space. The accounting was broken in a couple of ways: 1) We did not differentiate between user dma buffers and kernel dma buffers. 2) The ttm_bo_acc_size function is broken in that it a) Doesn't take into account the size of the optional dma address array, b) Doesn't take into account the fact that drivers typically embed the ttm_tt structure. This needs to be fixed in ttm, but meanwhile provide a vmwgfx-specific function to do the job.

A lockdep warning is hit when evicting surfaces and reserving the backup buffer. Since this buffer can only be reserved by the process holding the surface reservation or by the buffer eviction processes that use tryreserve, there is no real deadlock here, but there's no other way to silence lockdep than to use a tryreserve. This means the reservation might fail if the buffer is about to be evicted or swapped out, but we now have code in place to handle that reasonably well.

Use the new vma-manager infrastructure. This doesn't change any implementation details as the vma-offset-manager is nearly copied 1-to-1 from TTM. The vm_lock is moved into the offset manager so we can drop it from TTM. During lookup, we use the vma locking helpers to take a reference to the found object. In all other scenarios, locking stays the same as before. We always guarantee that drm_vma_offset_remove() is called only during destruction. Hence, helpers like drm_vma_node_offset_addr() are always safe as long as the node has a valid offset. This also drops the addr_space_offset member as it is a copy of vm_start in vma_node objects. Use the accessor functions instead. v4: - remove vm_lock - use drm_vma_offset_lock_lookup() to protect lookup (instead of vm_lock) Cc: Dave Airlie <airlied@redhat.com> Cc: Ben Skeggs <bskeggs@redhat.com> Cc: Maarten Lankhorst <maarten.lankhorst@canonical.com> Cc: Martin Peres <martin.peres@labri.fr> Cc: Alex Deucher <alexander.deucher@amd.com> Cc: Thomas Hellstrom <thellstrom@vmware.com> Signed-off-by: NDavid Herrmann <dh.herrmann@gmail.com> Reviewed-by: NDaniel Vetter <daniel.vetter@ffwll.ch> Signed-off-by: NDave Airlie <airlied@gmail.com>

All items on the lru list are always reservable, so this is a stupid thing to keep. Not only that, it is used in a way which would guarantee deadlocks if it were ever to be set to block on reserve. This is a lot of churn, but mostly because of the removal of the argument which can be nested arbitrarily deeply in many places. No change of code in this patch except removal of the no_wait_reserve argument, the previous patch removed the use of no_wait_reserve. v2: - Warn if -EBUSY is returned on reservation, all objects on the list should be reservable. Adjusted patch slightly due to conflicts. v3: - Focus on no_wait_reserve removal only.
