Right now all brcm2708 patches are extracted from the non-mainline raspberrypi/linux git tree. Many of them are hacks and/or are unneeded in LEDE. Raspberry Pi is getting better and better mainline support so it would be nice to finally start maintaining patches in a cleaner way: 1) Backport patches accepted in upstream tree 2) Start using upstream drivers 3) Pick only these patches that are needed for more complete support Handling above tasks requires grouping patches - ideally using the same prefixes as generic ones. It means we should rename existing patches to use some high prefix. This will allow e.g. use 0xx for backported code.

Subject: [PATCH] drm/vc4: Fix sending of page flip completion events in FKMS
|
|
mode.
|
|
|
|
In the rewrite of vc4_crtc.c for fkms, I dropped the part of the
|
|
CRTC's atomic flush handler that moved the completion event from the
|
|
proposed atomic state change to the CRTC's current state. That meant
|
|
that when full screen pageflipping happened (glxgears -fullscreen in
|
|
X, compton, por weston), the app would end up blocked firever waiting
|
|
to draw its next frame.
