Andy Gross of Texas Instruments has published initial support for graphics handling on the OMAP5 SoC. This support is for their open-source DRM kernel graphics driver.
The fifth-generation OMAP5 SoC from Texas Instruments is built around an ARM Cortex-A15 processor with two Cortex-M4 cores for offloading. On the graphics side there is two PowerVR SGX544MP graphics cores and a Texas Instruments 2D BitBlt graphics accelerator with a multi-pipe display subsystem. The two initial OMAP5 SoCs are the OMAP5430 and OMAP5432.
On Wednesday were two patches for the new support within OMAPDRM. Interestingly, the patches came from TI's Andy Gross rather than Rob Clark, but he did sign off on the code. One of the patches introduce power management support into the TI OMAP DRM graphics driver while the other is adding in the OMAP5 support. As has unfortunately been the case, this is only for the display/2D support and doesn't cover any 3D support from the Imagination PowerVR SGX graphics processors.
The patches can be found on dri-devel
. Unless there's another last-minute pull request for the Linux 3.8 kernel, this work will likely not be merged until Linux 3.9.
