drm/vmwgfx: Replace vmw_dma_buffer with vmw_buffer_object

2018-07-03T18:33:30+00:00

Initially vmware buffer objects were only used as DMA buffers, so the name DMA buffer was a natural one. However, currently they are used also as dumb buffers and MOBs backing guest backed objects so renaming them to buffer objects is logical. Particularly since there is a dmabuf subsystem in the kernel where a dma buffer means something completely different. This also renames user-space api structures and IOCTL names correspondingly, but the old names remain defined for now and the ABI hasn't changed. There are a couple of minor style changes to make checkpatch happy. Signed-off-by: Thomas Hellstrom Reviewed-by: Sinclair Yeh Reviewed-by: Deepak Rawat

drm/vmwgfx: Avoid pinning fbdev framebuffers

2018-03-22T11:08:23+00:00

fbdev framebuffers were previously pinned to be able to keep them mapped across updates. This commit introduces a mechanism that instead revalidates the map on each update, keeping the map cached across updates. The cached map is torn down if the underlying pages change. Typically on buffer object moves and swapouts. This should be nicer to the system when we have resource contention. Testing done: Basic fbdev functionality under Fedora 27.

drm/vmwgfx: Use the cpu blit utility for framebuffer to screen target blits

2018-03-22T11:08:23+00:00

This blit was previously performed using two large vmaps, one of which was teared down and remapped on each blit. Use the more resource- conserving TTM cpu blit instead. The blit is used in boundary-box computing mode which makes it possible to minimize the bounding box used in host operations. Signed-off-by: Thomas Hellstrom Reviewed-by: Brian Paul

drm/ttm: add bo as parameter to the ttm_tt_create callback
