Subject: [PATCH] HACK: drm: Bypass auth APIs by default
|
|
|
|
There're hacks in Rockchip's BSP kernels to ignore drm auth, so we can
|
|
bypass the related drm auth APIs here.
|
|
|
|
Bypass these auth APIs:
|
|
drmSetMaster, drmDropMaster.
|
|
|
|
Set these environments to enable:
|
|
"DRM_SET_MASTER", "DRM_DROP_MASTER".
|
|
