drm/amdgpu: update VCN codec support for Yellow Carp

2022-06-14T16:41:50Z

commit 97e50305542f384741a5b45699aba349fe9fca73 upstream. Supports AV1. Mesa already has support for this and doesn't rely on the kernel caps for yellow carp, so this was already working from an application perspective.

drm/atomic: Force bridge self-refresh-exit on CRTC switch

2022-06-14T16:41:50Z

commit e54a4424925a27ed94dff046db3ce5caf4b1e748 upstream. It's possible to change which CRTC is in use for a given connector/encoder/bridge while we're in self-refresh without fully disabling the connector/encoder/bridge along the way. This can confuse the bridge encoder/bridge, because (a) it needs to track the SR state (trying to perform "active" operations while the panel is still in SR can be Bad(TM)); and (b) it tracks the SR state via the CRTC state (and after the switch, the previous SR state is lost). Thus, we need to either somehow carry the self-refresh state over to the new CRTC, or else force an encoder/bridge self-refresh transition during such a switch. I choose the latter, so we disable the encoder (and exit PSR) before attaching it to the new CRTC (where we can continue to assume a clean (non-self-refresh) state). This fixes PSR issues seen on Rockchip RK3399 systems with drivers/gpu/drm/bridge/analogix/analogix_dp_core.c. Change in v2: - Drop "->enable" condition; this could possibly be "->active" to reflect the intended hardware state, but it also is a little over-specific. We want to make a transition through "disabled" any time we're exiting PSR at the same time as a CRTC switch.

drm/bridge: analogix_dp: Support PSR-exit to disable transition

2022-06-14T16:41:50Z

commit ca871659ec1606d33b1e76de8d4cf924cf627e34 upstream. Most eDP panel functions only work correctly when the panel is not in self-refresh. In particular, analogix_dp_bridge_disable() tends to hit AUX channel errors if the panel is in self-refresh. Given the above, it appears that so far, this driver assumes that we are never in self-refresh when it comes time to fully disable the bridge. Prior to commit 846c7dfc1193 ("drm/atomic: Try to preserve the crtc enabled state in drm_atomic_remove_fb, v2."), this tended to be true, because we would automatically disable the pipe when framebuffers were removed, and so we'd typically disable the bridge shortly after the last display activity. However, that is not guaranteed: an idle (self-refresh) display pipe may be disabled, e.g., when switching CRTCs. We need to exit PSR first. Stable notes: this is definitely a bugfix, and the bug has likely existed in some form for quite a while. It may predate the "PSR helpers" refactor, but the code looked very different before that, and it's probably not worth rewriting the fix.

drm/amd/pm: use bitmap_{from,to}_arr32 where appropriate
