With the shadow buffer support from generic framebuffer emulation, it's possible now to have runpm kicked when no update for console. Change-Id: I285472c9100ee6f649d3f3f3548f402b9cd34eaf Signed-off-by: Evan Quan <evan.quan@xxxxxxx>
That's a really nice cleanup, but somebody with a bit more background in the fb code should probably take a look as well.
So adding Thomas as well. On the other hand feel free to add an Acked-by: Christian König <christian.koenig@xxxxxxx>.
Christian.
