drm/ttm: Fix two race conditions + fix busy codepaths

2011-03-21T19:45:30+00:00

commit 1df6a2ebd75067aefbdf07482bf8e3d0584e04ee upstream.

This fixes a race pointed out by Dave Airlie where we don't take a buffer
object about to be destroyed off the LRU lists properly. It also fixes a rare
case where a buffer object could be destroyed in the middle of an
accelerated eviction.

The patch also adds a utility function that can be used to prematurely
release GPU memory space usage of an object waiting to be destroyed.
For example during eviction or swapout.

The above mentioned commit didn't queue the buffer on the delayed destroy
list under some rare circumstances. It also didn't completely honor the
remove_all parameter.

drm/vmwgfx: Drop scanout flag compat and add execbuf ioctl parameter members. Bumps major.

Even if this bumps the version to 1 it does not mean the driver is
out of staging. From what we know this is the last backwards
incompatible change to the driver.

drm/vmwgfx: Update the user-space interface.

2010-02-11T01:58:09+00:00

When time-based throttling is implemented, we need to bump minor.
When the old way of detecting scanout is removed, we need to bump major.
In the meantime, this change should not break existing user-space.

On nv50, this will be needed by applications using CUDA to know
how much stack/local memory to allocate.
