This change makes the names of Broadcom targets consistent by using the common notation based on SoC/CPU ID (which is used internally anyway), bcmXXXX instead of brcmXXXX. This is even used for target TITLE in make menuconfig already, only the short target name used brcm so far. Despite, since subtargets range from bcm2708 to bcm2711, it seems appropriate to use bcm27xx instead of bcm2708 (again, as already done for BOARDNAME). This also renames the packages brcm2708-userland and brcm2708-gpu-fw. Signed-off-by: Adrian Schmutzler <freifunk@adrianschmutzler.de> Acked-by: Álvaro Fernández Rojas <noltari@gmail.com>

Subject: [PATCH] drm/v3d: HACK: gut runtime pm for now.
|
|
|
|
Something is still unstable -- on starting a new glxgears from an idle
|
|
X11, I get an MMU violation in high addresses. The CTS also failed
|
|
quite quickly. With this, CTS progresses for an hour before OOMing
|
|
(allocating some big buffers when my board only has 600MB available to
|
|
Linux)
