drm/ttm, drm/vmwgfx: Relax permission checking when opening surfaces

2017-04-12T10:38:33+00:00

commit fe25deb7737ce6c0879ccf79c99fa1221d428bf2 upstream.

Previously, when a surface was opened using a legacy (non prime) handle,
it was verified to have been created by a client in the same master realm.
Relax this so that opening is also allowed recursively if the client
already has the surface open.

This works around a regression in svga mesa where opening of a shared
surface is used recursively to obtain surface information.

drm/ttm: Make ttm_bo_mem_compat available

2016-07-27T16:47:35+00:00

commit 94477bff390aa4612d2332c8abafaae0a13d6923 upstream.

There are cases where it is desired to see if a proposed placement
is compatible with a buffer object before calling ttm_bo_validate().

drm/ttm: device address space != CPU address space

2015-03-04T23:04:39+00:00

We need to store device offsets in 64 bit as the device
address space may be larger than the CPU's.

Fixes GPU init failures on radeons with 4GB or more of
vram on 32 bit kernels.  We put vram at the start of the
GPU's address space so the gart aperture starts at 4 GB
causing all GPU addresses in the gart aperture to get
truncated.

drm/ttm: optionally move duplicates to a separate list

2014-12-03T23:26:52+00:00

This patch adds an optional list_head parameter to ttm_eu_reserve_buffers.
If specified duplicates in the execbuf list are no longer reported as errors,
but moved to this list instead.

drm/ttm: kill off some members to ttm_validate_buffer

2014-09-01T08:18:03+00:00

This reorders the list to keep track of what buffers are reserved,
so previous members are always unreserved.

This gets rid of some bookkeeping that's no longer needed,
while simplifying the code some.

drm/ttm: add interruptible parameter to ttm_eu_reserve_buffers

It seems some drivers really want this as a parameter,
like vmwgfx.

drm/ttm: kill fence_lock

No users are left, kill it off! :D
Conversion to the reservation api is next on the list, after
that the functionality can be restored with rcu.
