Marek Olšák, the prolific independent contributor to Mesa/Gallium3D and the open-source Radeon Linux graphics driver, has landed a number of commits today in Mesa pertaining to MSAA, a.k.a. multi-sample anti-aliasing for newer Radeon GPUs.

The landed work today includes the enabling of MSAA support for Radeon HD 5000 series GPUs -- the "Evergreen" generation of ATI/AMD graphics processors. The Evergreen MSAA support requires a recent Radeon DRM driver and will only work for this generation of graphics processors and supports 2x, 4x, and 8x MSAA modes.

The commits pushed by Marek today include:

- gallium/u_blitter: document custom meta helpers
- r600g: disable handling of DISCARD_RANGE
- r600g: implement timestamp query and get_timestamp hook
- r600g: enable MSAA on evergreen by default
- r600g: implement copying between MSAA textures
- r600g: implement MSAA color resolve
- r600g: implement MSAA depth-stencil decompression and resolve
- r600g: implement TXQ_LZ opcode
- r600g: implement MSAA rendering and texturing for evergreen and cayman
- r600g: implement set_sample_mask
- r600g: implement alpha-to-coverage
- r600g: implement alpha-to-one
- r600g: remove support for 3-channel colorbuffers
- configure.ac: bump libdrm_radeon requirement to 2.6.38
- winsys/radeon: print error if CS is overflowed
- gallium/u_blitter: implement X and Y texture flipping
- gallium/u_blitter: implement blitting multisample resources
- gallium: add TGSI support for multisample textures
- gallium/tgsi: fix TGSI text parser
- gallium/u_blit: set dst format from pipe_resource, not pipe_surface
- gallium: make pipe_box signed in order to represent flipped blits
- st/mesa: don't clamp fragment color with integer colorbuffer
- mesa: flush vertices in test_framebuffer_completeness

This work will be part of what's expected to be the Mesa 9.0 release in about one month's time.
