MESA --
One of the latest initiatives worked on by Eric Anholt at Broadcom for the VC4 Gallium3D driver -- the open-source driver used most famously by the Raspberry Pi hardware -- is lower memory use.

Over the past week he's been working on lowering the memory use for the VC4 open-source Linux driver stack. Eric ended up making various fixes and optimizations to reduce the memory consumption, which is important considering the limited RAM available on the Raspberry Pi boards.

In addition, Eric has been working on GLSL IR to NIR direct translations and various other improvements to this open-source driver. Those interested in the technical details can see Eric's blog for information regarding the progress over the past week.
