drm/vmwgfx: Add max surface memory param

2013-12-09T07:50:23+00:00

Userspace uses this to workaround overcommit issues
by flushing the command stream early.

drm/vmwgfx: Fix dma buffer memory size accounting

2013-12-04T20:03:56+00:00

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.

drm/vmwgfx: Fix up and comment the dumb buffer implementation

Allocation was duplicating code. Comments were missing.

drm/vmwgfx: Correctly set the enabled state on crtcs

2013-12-04T20:03:45+00:00

Failure to do this would make the drm_mode_get_crtc ioctl return
without crtc mode info, indicating that no mode was set.

Should we need to share dma buffers using prime, let's make them prime

Also provide a completely dumb dma-buf ops implementation.
Once we have other virtual dma-buf aware devices, we need to provide
something better.

drm/vmwgfx: Fix false lockdep warning

2013-11-18T08:40:05+00:00

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.
