The hw cursor is relatively adept at triggering underflows, which manifest as a "blue flash" (since blue is configured as the underflow color). Juggle a few things around to tighten up the timing for setting cursor registers in DONE irq. And most importantly, don't ever disable the hw cursor. Instead flip it to a blank/empty cursor. This seems far more reliable, as even simply clearing the cursor-enable bit (with no other updates in previous/ following frames) can in some cases cause underflow. v1: original v2: add missing locking spotted by Micah Cc: Micah Richert <richert@braincorporation.com> Signed-off-by: Rob Clark <robdclark@gmail.com> |
