Eric Anholt Makes Progress With Broadcom VC4 Graphics Driver

One month ago Linux developer Eric Anholt left Intel to work at Broadcom. Eric, a long-time contributor to the open-source Linux graphics stack, is now tasked at Broadcom with developing a DRM driver and Mesa/Gallium3D driver for Broadcom's "VC4" graphics hardware, which is found within the Raspberry Pi.

Eric was quick to get working on the DRM and Gallium3D driver for Broadcom hardware. He's been making good progress while the Gallium3D and DRM code remain outside of Mesa and the Linux kernel, respectively. There's a lot of work left before he can think about merging the code.

Anholt wrote a new blog post on Tuesday evening entitled vc4 driver month 1 . In the post Eric shares that last week he got his first texture sampling to work in simulation and that handling texturing on the VC4 hardware is a pain to do safely. Eric's been working on safe code for the kernel and user-space driver to handle the texturing, but there's still a lot of work left.

Once the texturing work is out of the way and other necessary prerequisites, Eric intends to get GLAMOR acceleration up and running on the Raspberry Pi for performing 2D acceleration via OpenGL with the X.Org Server.
