Rob Clark has queued up some interesting changes to his "MSM" DRM driver for reverse-engineered open-source Qualcomm Snapdragon display support. The changes queued up for the Linux 3.13 kernel will include PRIME and render nodes capabilities.
After a year of working on the "Freedreno" Gallium3D user-space driver and getting that up to speed for Qualcomm Adreno/Snapdragon support, for the past few months he's been working on a complementary kernel driver rather than relying upon Qualcomm's Android-focused kernel layer. Rob's MSM DRM driver was merged in Linux 3.12
and coming up for Linux 3.13 it will include a number of new features.
The work that Rob has ready for Linux 3.13 with this Qualcomm DRM graphics driver is DRI PRIME support, support for render nodes, updated header files, plane support, and a couple of other changes.
The pull request getting the new MSM code into the drm-next tree can be found on the dri-devel mailing list
. Besides this exciting ARM DRM driver, the Marvell Armada DRM driver should be merged
to make for this next kernel cycle to be more exciting on the ARM graphics front.
