drm/amdgpu/display: handle multiple numbers of fclks in dcn_calcs.c (v2)

2020-02-24T07:37:03+00:00

[ Upstream commit c37243579d6c881c575dcfb54cf31c9ded88f946 ]

We might get different numbers of clocks from powerplay depending
on what the OEM has populated.

v2: add assert for at least one level

what the windows driver does.

radeon: insert 10ms sleep in dce5_crtc_load_lut

[ Upstream commit ec3d65082d7dabad6fa8f66a8ef166f2d522d6b2 ]

Per at least one tester this is enough magic to recover the regression

    drm/fb-helper: factor out pseudo-palette

which for radeon had the side-effect of refactoring out a seemingly
redudant writing of the color palette.

10ms in a fairly slow modeset path feels like an acceptable form of
duct-tape, so maybe worth a shot and see what sticks.

drm/nouveau/disp/nv50-: prevent oops when no channel method map provided

2020-02-24T07:36:59+00:00

[ Upstream commit 0e6176c6d286316e9431b4f695940cfac4ffe6c2 ]

The implementations for most channel types contains a map of methods to
priv registers in order to provide debugging info when a disp exception
has been raised.

This info is missing from the implementation of PIO channels as they're
rather simplistic already, however, if an exception is raised by one of
them, we'd end up triggering a NULL-pointer deref.  Not ideal...
