bool "MSM DRM register logging"
depends on DRM_MSM

help
Compile in support for logging register reads/writes in a format
that can be parsed by envytools demsm tool. If enabled, register
logging can be switched on via msm.reglog=y module param.

help
Enable userspace that has CAP_SYS_RAWIO to submit GPU commands
that are run from RB instead of IB1. This essentially gives
userspace kernel level access, but is useful for firmware
debugging.
Only use this if you are a driver developer. This should *not*
be enabled for production kernels. If unsure, say N.

display support is enabled through this config option. It can
be primary or secondary display on device.
