* drm/vmwgfx: Don't send bad flags to the hostJakob Bornecrantz2010-02-013-1/+27

* drm/vmwgfx: Request SVGA version 2 and bail if not foundPeter Hanzel2010-02-011-0/+11
| | | | | | | | This fixes the driver not loading on older versions of VMware. Signed-off-by: Peter Hanzel <hanzelpeter@gmail.com> Signed-off-by: Jakob Bornecrantz <jakob@vmware.com> Signed-off-by: Dave Airlie <airlied@redhat.com>

* drm/vmwgfx: Optimize memory footprint for DMA buffers.Thomas Hellstrom2010-01-254-1/+30
| | | | | | | | | | | 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.

* drm/vmwgfx: Implement basic pm operations.Thomas Hellstrom2010-01-142-1/+63
| | | | | | | | | | | | 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.

* drm/vmwgfx: Implement a swap_notify callback.Thomas Hellstrom2010-01-141-1/+7
| | | | | | | Unbind GMR bindings on the buffer about to be swapped out. Signed-off-by: Thomas Hellstrom <thellstrom@vmware.com> Signed-off-by: Dave Airlie <airlied@redhat.com>
* drm/vmwgfx: Use bo_driver::move_notify to unbind GMRs.Thomas Hellstrom2010-01-145-29/+22
| | | | | | | | This was previously done explicitly for overlay- and fb buffers. Now it's done for any buffer leaving the SYSTEM memory region. Signed-off-by: Thomas Hellstrom <thellstrom@vmware.com> Signed-off-by: Dave Airlie <airlied@redhat.com>
* drm/vmwgfx: Make fence sequences continous across a VT switch.Thomas Hellstrom2010-01-142-2/+2
| | | | | | | | | | 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. Signed-off-by: Thomas Hellstrom <thellstrom@vmware.com> Signed-off-by: Dave Airlie <airlied@redhat.com>
* drm/vmwgfx: Fix an error path causing an oops.Thomas Hellstrom2010-01-141-18/+21
| | | | | | | | | 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. Signed-off-by: Thomas Hellstrom <thellstrom@vmware.com> Signed-off-by: Dave Airlie <airlied@redhat.com>
* drm/vmwgfx: Don't promote updates from GMR-backed scanouts to fullscreen.Thomas Hellstrom2010-01-141-7/+5
| | | | | | | | That's unnecessary since partial screen updates from GMRs are fast. Also fix cliprect pointer dereferencing Signed-off-by: Thomas Hellstrom <thellstrom@vmware.com> Signed-off-by: Dave Airlie <airlied@redhat.com>
* drm/vmwgfx: Use TTM handles instead of SIDs as user-space surface handles.Thomas Hellstrom2009-12-234-111/+209
| | | | | | | | | | | 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.

* drm/vmwgfx: Return -ERESTARTSYS when interrupted by a signal.Thomas Hellstrom2009-12-233-10/+6
| | | | | | | | Fixes for TTM API change. Signed-off-by: Thomas Hellstrom <thellstrom@vmware.com> Signed-off-by: Jakob Bornecrantz <jakob@vmware.com> Signed-off-by: Dave Airlie <airlied@redhat.com>
* drm/vmwgfx: Fix unlocked ioctl and add proper access controlThomas Hellstrom2009-12-231-28/+19
| | | | | | | | | This fixes up vmwgfx for the unlocked ioctl code to avoid doing it in the driver. Also adds ioctl flags. Signed-off-by: Thomas Hellstrom <thellstrom@vmware.com> Signed-off-by: Jakob Bornecrantz <jakob@vmware.com> Signed-off-by: Dave Airlie <airlied@redhat.com>
* drm/vmwgfx: Add DRM driver for VMware Virtual GPUJakob Bornecrantz2009-12-1518-0/+7337
| | | | | | | | | | | | 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.

* drm/vmwgfx: Add svga headers for vmwgfx driverJakob Bornecrantz2009-12-155-0/+3474
These headers are shared between multiple place where different coding standards apply. They will be fixed up at a later time. Signed-off-by: Thomas Hellström <thellstrom@vmware.com> Signed-off-by: Jakob Bornecrantz <jakob@vmware.com> Signed-off-by: Dave Airlie <airlied@redhat.com>
