From Phoronix:

In the second NDA-free documentation dump, AMD has just released programming data on the M76 and RS690 graphics processors. While the RadeonHD developers have already had these documents, this information will help the free software community in understanding the internal workings of AMD's graphics processors. In this article, we have information on this just-released data as well as what else the community can expect in the way of documentation in the near future.

Read the full story:

Back on September 12, 2007 at the X Developer Summit, AMD had released 900+ pages of GPU specifications, which was made up of register reference guides for the RV630 and M56 GPUs. Although minor, this documentation had led to improvements with the open-source Avivo driver on the same-day, and this information has certainly gone a long way with helping the RadeonHD driver.

It has been nearly four months since the RV630 and M56 register reference guides were released, and no other documentation has been released because of the holidays and AMD bringing on additional staff. Alex Deucher, who is known for his work on the open-source xf86-video-ati driver, had joined AMD to continue in his open-source involvement and preparing documentation for these release dumps. As we have previously shared, this work involves AMD employees and their legal advisors going through their internal documentation, determining what is authorized for release, and what isn't (anything that may cause legal problems, information pertaining to future ASICs, etc). AMD has also had to fill in areas where their internal documentation is less than complete.
