drm/amdgpu: fix unload driver issue for virtual display

2017-12-09T21:01:53+00:00

[ Upstream commit 3a1d19a29670aa7eb58576a31883d0aa9fb77549 ]

Virtual display doesn't allocate amdgpu_encoder when initializing,
so will get invaild pointer if try to free amdgpu_encoder when
unloading driver.

drm/amdgpu: mark symbols static where possible

2016-09-22T14:24:17+00:00

We get 7 warnings when building kernel with W=1:

drivers/gpu/drm/amd/amdgpu/dce_virtual.c:136:6: warning: no previous prototype for 'dce_virtual_set_vga_render_state' [-Wmissing-prototypes]

In fact, all of the functions are only used in the file
in which they are declared and don't need a declaration,
but can be made static.

So this patch marks both functions with 'static'.

drm/amdgpu: Hardcode virtual DCE vblank / scanout position return values

2016-08-17T19:42:50+00:00

For virtual display feature, by hardcoding 0 for the vblank counter and
-EINVAL for the scanout position return value, we signal to the core DRM code that there are
no hardware counters we can use for these.

Now we can program a flip during a vertical blank period, if it's the
one targeted by the flip (or a later one). This allows simplifying
amdgpu_flip_work_func considerably.

agd: update dce_virtual.c as well.
