[Mesa-dev] [PATCH v2 0/4] Android kms_swrast support

This series implements kms_swrast support for the Android
platform. And since having to debug a null pointer dereference,
simplify that process for the next guy.
As it stands now, any kernel must have the following ioctls flagged with
DRM_RENDER_ALLOW, which isn't the case in the mainline kernel.
While it would be possible to open a non-render node to pass the
authentication check, this would still cause authentication issues
when the /dev/dri/cardX node needs to be opened as master by both mesa
and the compositor.
I don't know how acceptable this series is for upstreaming, while relying on
a non-mainline kernel. I think the policy is to not accept changes that
don't have both a user and kernel space solution in place.
Like I noted yesterday the alternative to using dumb buffers and having
authentication issues is using VGEM, which is new territory to me, and it would
take me a little bit of time to figure exactly how it fits into the current
Input, like noted before, is very much welcome.
The series is available here:
Changes since v1:
- Added r-b
- Added patch for asserting on failed pipe_transfer_map()
Changes since RFC:
- Dropped "st/dri: Allow kms_swrast to work without a device FD"
- Removed software renderer fallback from platform_android
- Fixed various smaller issues
Rob Herring (1):
android: Build kms_swrast for the Android platform
Robert Foss (3):
softpipe: Add assert verifying successful pipe_transfer_map
egl/android: Add Android property for forcing software rendering
platform/android: Enable kms_swrast fallback
