drm/vmwgfx: Add surface define v4 command

2020-03-23T21:48:57+00:00

Surface define v4 added new member buffer_byte_stride. With this patch
add buffer_byte_stride in surface metadata and create surface using new
command if support is available.

Also with this patch replace device specific data types with kernel
types.

drm/vmwgfx: add ioctl for messaging from/to guest userspace to/from host

2020-01-15T10:54:16+00:00

Up to now, guest userspace does logging directly to host using essentially
the same rather complex port assembly stuff as the kernel.
We'd rather use the same mechanism than duplicate it (it may also change in
the future), hence add a new ioctl for relaying guest/host messaging
(logging is just one application of it).

drm/vmwgfx: Add surface dirty-tracking callbacks

2019-11-06T14:45:32+00:00

Add the callbacks necessary to implement emulated coherent memory for
surfaces. Add a flag to the gb_surface_create ioctl to indicate that
surface memory should be coherent.
Also bump the drm minor version to signal the availability of coherent
surfaces.

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.
