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[1], which isn't the case in the mainline kernel. DRM_IOCTL_MODE_CREATE_DUMB DRM_IOCTL_MODE_MAP_DUMB 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[2] 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 kms_swrast approach. Input, like noted before, is very much welcome.
