drm/i915/fbdev: Restore physical addresses for fb_mmap()

2019-11-21T08:09:22Z

fbdev uses the physical address of our framebuffer for its fb_mmap() routine. While we need to adapt this address for the new io BAR, we have to fix v5.4 first! The simplest fix is to restore the smem back to v5.3 and we will then probably have to implement our fbops->fb_mmap() callback to handle local memory.

drm/amd/powerplay: correct fine grained dpm force level setting

2019-11-20T23:40:21Z

For fine grained dpm, there is only two levels supported. However to reflect correctly the current clock frequency, there is an intermediate level faked. Thus on forcing level setting, we need to treat level 2 correctly as level 1. Signed-off-by: Evan Quan Reviewed-by: Kevin Wang Signed-off-by: Alex Deucher

drm/i915: Protect request peeking with RCU

2019-11-18T19:25:16Z

Since the execlists_active() is no longer protected by the engine->active.lock, we need to protect the request pointer with RCU to prevent it being freed as we evaluate whether or not we need to preempt.
