Did Texas Instruments tell the developer to halt work on this driver he was writing in his spare time? Did Linaro have issues with it? (Rob Clark is a TI employee that also contributes to Linaro.) Did Qualcomm try to pick him up?
The Freedreno Git repository (on Gitorious.org) is still alive and well. There's even been some Freedreno commits from time to time (this is the name of the project). The latest commit at the time of publishing was one done on 20 May and previous to that there were a few at the beginning of May, but not many.
The official response that Rob Clark provided me with about the state of the reverse-engineered open-source driver for TI's competitor was:
hey.. slowly but surely making progress.. mainly been looking at the 3d side of things. Have been travelling for last couple weeks (and in hong kong this week for linaro connect) so hasn't been as much progress. I have started a 'fdre' branch where I'm starting to write code along the lines of limare to drive the GPU, although it is still a ways from having something enough to make any announcement. But once I get back home I should start having some more time to spend on it.So Freedreno appears to still be happening, just not at a blistering pace. Though the open-source ARM Mali driver is also moving slowly (an update from last weekend). I've heard from others that Texas Instruments apparently isn't too happy about the whole situation, but alas it appears he's still free to work on this code in his limited spare time.
