Raspberry Pi DRM+Gallium3D Driver Makes Great Progress In One Week

Last week Eric Anholt left Intel's Linux graphics driver team to go work for Broadcom developing a VC4 DRM/KMS and Gallium3D driver for the GPU that supports the Raspberry Pi.

Eric ended up making more progress in his first week than he anticipated in starting off this new open-source Linux graphics driver project. He ended up getting his work items done that originally he anticipated would take him about one month. The basic "hack driver" is now working to run triangle code running on a kernel with a relocations-based GEM interface. Thursday he already started on the Broadcom VC4 Gallium3D driver, which in turn is based upon the Freedreno driver for Qualcomm's ARM hardware.

Eric's basic VC4 kernel driver is far from complete, insecure, running synchronously, and has other issues, but project is quickly coming about. Eric's also praised his work experience thus far at Broadcom. Eric's current kernel code can be found via this GitHub repository while he hasn't yet opened up the repository for his VC4 Gallium3D driver code.
