drm/vmwgfx: Fix regression caused by "drm/ttm: make ttm reservation calls behave like reservation calls"

2014-02-13T21:55:43+00:00

commit cf5e3413337309050c05e13dcebe85b7194a21e5 upstream. The call to ttm_eu_backoff_reservation() as part of an error path would cause a lock imbalance if the reservation ticket was not initialized. This error is easily triggered from user-space by submitting a bogus command stream.

drm/vmwgfx: Fix the driver for large dma addresses

2014-02-13T21:55:43+00:00

commit 0d00c488f3de59d19784d5ce774528acaa194525 upstream. With dma compliance / IOMMU support added to the driver in kernel 3.13, the dma addresses can exceed 44 bits, which is what we support in 32-bit mode and with GMR1. So in 32-bit mode and optionally in 64-bit mode, restrict the dma addresses to 44 bits, and strip the old GMR1 code.

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. Signed-off-by: Thomas Hellstrom Reviewed-by: Jakob Bornecrantz

drm/vmwgfx: Correctly set the enabled state on crtcs

Failure to do this would make the drm_mode_get_crtc ioctl return without crtc mode info, indicating that no mode was set. Signed-off-by: Thomas Hellstrom Reviewed-by: Jakob Bornecrantz
