SimpleDRM Will Likely Be Merged In Linux 3.15

Besides going for enabling DRM render-nodes by default, David Herrmann is looking to land a bunch of other DRM patches for the Linux 3.15 kernel.

David Herrmann sent in three drm-next pull requests today to Red Hat's David Airlie. The three rounds today have trivial/minor fixes, a DRM-minor rework, and the third branch contains various DRM-anon work. The last series allows for DRM modules to be unloaded from the kernel after being loaded, which is something that previously didn't work for DRM graphics drivers, for switching to a different kernel graphics driver.

Herrmann wrote at the beginning of today's work that he might also go for landing SimpleDRM with Linux 3.15. SimpleDRM is a generic (and sample) DRM driver that is similar to efifb, vesafb, offb, simplefb, and other basic frame-buffer graphics drivers except this one fits within the Direct Rendering Manager infrastructure.

Herrmann did a major rewrite of SimpleDRM at the beginning of this year. Being a universal graphics driver, SimpleDRM obviously has no hardware acceleration support but can consolidate the other aforementioned frame-buffer drivers within the kernel. SimpleDRM can then also interface with the xf86-video-modesetting DDX driver. SimpleDRM is part of David's effort for killing CONFIG_VT and other big projects David Herrmann has been working on in recent times.

David didn't call for the SimpleDRM pull request today but he says if nothing breaks this week after testing he will send in the new driver for hopeful merging into Linux 3.15 at the end of the week.
