drm/amdgpu: create fence slab once when amdgpu module init.

2016-05-13T18:30:22+00:00

This avoids problems with multiple GPUs.  For example,
if the first GPU failed before amdgpu_fence_init() was
called, amdgpu_fence_slab_ref is still 0 and it will
get decremented in amdgpu_fence_driver_fini().  This
will lead to a crash during init of the second GPU since
amdgpu_fence_slab_ref is not 0.

v2: add functions for init/exit instead of
    moving the variables into the driver.

drm/amdgpu: use fence_context to judge ctx switch v2

2016-05-11T16:31:27+00:00

Use of the ctx pointer is not safe, because they are likely already
be assigned to another ctx when doing comparing.

v2: recreate from scratch, avoid all unnecessary changes.

drm/amdgpu: Support DRM_MODE_PAGE_FLIP_ASYNC (v2)

2016-05-11T16:31:25+00:00

When this flag is set, we program the hardware to execute the flip
during horizontal blank (i.e. for the next scanline) instead of during
vertical blank (i.e. for the next frame).
