To those who have been curious what I was up to: I wasn't sure when I could announce my new projecct, I just got the ack day before yesterday, and I've been a little busy.
I'm working toward building a Mesa driver for Broadcom VC4 (aka Raspberry Pi). At the moment I'm still bringing up the DRM side of things, but I hope to be doing bits of userspace in the next few days. Current status is I have a skeleton DRM KMS driver that's going to talk to the firmware for modesetting, and now I'm starting on the execution side of things. I'm probably going to start out doing a gallium driver for simplicity, to avoid having to do all the DRI crap we've got in brw_context.c and texture miptree validation and getting user data into VBOs and all that other almost-boilerplate. Long term I may end up switching to classic so I can get swrast fallbacks and the ability to implement single-copy manually-tiled TexImage uploads like. For now I want to get to drawing triangles as soon as I can. Major thanks go to Simon Hall, whose port of the 2708 android driver code drop is what I've been using as a reference for how the 3D engine commands are submitted.
