LXer: A Birthday Present from Broadcom

Published at LXer:

In common with every other ARM-based SoC, using the VideoCore IV 3d graphics core on the Pi requires a block of closed-source binary driver code (a “blob”) which talks to the hardware. In our case, this blob runs on the VPU vector processor of the BCM2835 (the SOC or System On a Chip at the heart of the Raspberry Pi); our existing open-source graphics drivers are a thin shim running on the ARM11, which talks to that blob via a communication driver in the Linux kernel. The lack of true open-source graphics drivers and documentation is widely acknowledged to be a significant problem for Linux on ARM, as it prevents users from fixing driver bugs, adding features and generally understanding what their hardware is doing.
