Thomas Hellstrom 8ba5152a3a drm/vmwgfx: Optimize memory footprint for DMA buffers.
Use VRAM whenever there is free space for DMA buffers,
but use system GMR memory if using VRAM would cause an eviction.

This significantly reduces the guest system memory usage for
VMs with a large amount of VRAM allocated.

Thomas Hellstrom d9f36a0051 drm/vmwgfx: Implement basic pm operations.
Currently we really only support S3, since the device doesn't support
saving of the 3D state.

On S3/S4, move all buffer objects to swappable memory and take down
GMR bindings. We need to do that from a PM notifier since we can't
do persistant memory allocations from the standard PM callbacks.

Thomas Hellstrom effe1105be drm/vmwgfx: Use bo_driver::move_notify to unbind GMRs.
This was previously done explicitly for overlay- and fb buffers.
Now it's done for any buffer leaving the SYSTEM memory region.

Thomas Hellstrom 7704befbd5 drm/vmwgfx: Make fence sequences continous across a VT switch.
A vt switch in stealth mode would take down the FIFO, and re-
initialize fence sequence numbers. This patch
saves the current state of the fence sequence when the FIFO is
disabled.

Thomas Hellstrom 50ec3b7c35 drm/vmwgfx: Fix an error path causing an oops.
An error happening before the snooper.image member had been set up
would cause a kfree of an arbitrary pointer. Set up the snooper.image
member early.

Thomas Hellstrom df1c93bae2 drm/vmwgfx: Don't promote updates from GMR-backed scanouts to fullscreen.
That's unnecessary since partial screen updates from GMRs are fast.
Also fix cliprect pointer dereferencing

Thomas Hellstrom 7a73ba7469 drm/vmwgfx: Use TTM handles instead of SIDs as user-space surface handles.
Improve the command verifier to catch all occurences of surface handles,
and translate to SIDs.

This way DMA buffers and 3D surfaces share a common handle space,
which makes it possible for the kms code to differentiate.

Jakob Bornecrantz fb1d9738ca drm/vmwgfx: Add DRM driver for VMware Virtual GPU
This commit adds the vmwgfx driver for the VWware Virtual GPU aka SVGA.
The driver is under staging the same as Nouveau and Radeon KMS. Hopefully
the 2D ioctls are bug free and don't need changing, so that part of the
API should be stable. But there there is a pretty big chance that the 3D API
will change in the future.
