not a review yet, but when testing and the display sets a mode,
I always get a bunch of
rockchip-drm display-subsystem: [drm] *ERROR* POST_BUF_EMPTY irq err at vp0
messages in the log (initial mode to console, starting glmark2 from console,
stopping glmark2 to the console).
I'm not sure what is up with that, have you seen these messages as well
at some point?
Yes, it will raise POST_BUF_EMPTY when set a mode, it needs some fix
like [0]:
I still trying to find a appropriate way to do it with the upstream
code, as it doesn't affect the
real display function(I must admit that the POST_BUF_EMPTY irq is very
annoying), so l let it as
it is in the current version.
By the way, can you see the glmark2 rending on your HDMI monitor now?
