RE:
Intel(r) G45 Programmer's Reference Manual
________________________________
We are pleased to announce that the Intel(r) G45 Express Chipset [Graphics and
Memory Controller Hub-GMCH] Programmer's Reference Manual (PRM) is now publicly
available! The PRM resides on the Linux Graphics website
(http://intellinuxgraphics.org/index.html) as well as the Visual Computing
Training website
(http://moss.amr.ith.intel.com/sites/VCG/VCG%20Training/default.aspx).
The PRM describes the architectural behavior and programming environment of the
chipset and graphics devices. The GMCH's Graphics Controller (GC) contains an
extensive set of registers and instructions for configuration, 2D, 3D, and
Video systems. The PRM describes the register, instruction, and memory
interfaces and the device behaviors as controlled and observed through those
interfaces. The PRM also describes the registers and instructions and provides
detailed bit/field descriptions. This information is critical to the
development and maintenance of Intel graphics drivers for this hardware.
Many thanks to the Graphics Engineering team and the Open Source Technology
Center for their work in identifying the appropriate material to include in the
PRM. We would like to recognize Patricia Langstraat for her technical writing
prowess as well as Eric Anholt for his help in reviewing the draft PRM
material. Others on Jeff Bock's team were invaluable in their efforts to
ensure this PRM contains useful information for the open source community.
