Freedreno MSM Driver Has Big Changes For Linux 3.19 Kernel

Written by Michael Larabel in Linux Kernel on 17 November 2014 at 08:49 AM EST. 3 Comments
Rob Clark on Sunday submitted his "msm-next" pull request for the DRM-Next Git tree for pulling into the Linux 3.19 kernel.

Most notable for this MSM DRM driver that's associated with the Freedreno driver project is the support for the Qualcomm Adreno A4xx series. The Qualcomm Innovation Center added the A4xx hardware support to the open-source DRM/KMS driver as a surprise move. Meanwhile, Rob Clark of Red Hat took to writing the Gallium3D support that's now in Mesa Git master following the recent Mesa 10.4 branching.

Besides landing the A4xx GPU support, there's MDP4/HDMI/core changes for atomic helpers and various other code clean-ups, fixes, and other refactoring. The changes for the Linux 3.19 cycle yield almost four thousand lines of new code. Rob might also be sending in another msm-next pull request in the coming days. More details via this pull request.
