Hi list, I've been working on i965g, a new pipe driver for Intel GEN6 (and later), for a while now. I would like to know if there is any interest in it and if it can be merged upstream. The code is currently available here
https://github.com/olvaffe/mesa/tree/i965g The project was started for my own fun and for self-learning. It was later sponsored by LunarG. While it is still new, it does work for many of mesa-demos. Right now it passes 6884 of 7547 piglit quick-driver.tests. I also tried it with gnome-shell, OpenArena, and Nexuiz, and they all seem to work. The driver is written from scratch. However, it follows classic i965 driver for many of the design decisions. It comes with its own toy compiler to translate TGSI tokens to GEN instructions. The compiler still lacks several functions (register spilling and most TGSI indirections), but more importantly, almost no optimization is performed. It thus generates much worse code comparing to that generated by classic i965. I rebased the code tonight and cleaned up the history. The branch now has 24 new commits on top of master winsys/intel: new winsys for intel i965g: new pipe driver for Intel GEN6+ i965g: add debug flags settable through I965_DEBUG i965g: hook up pipe_screen param and fence functions i965g: add functions to translate pipe enums to HW enums i965g: hook up pipe screen format functions i965g: hook up pipe screen resource functions i965g: add command parser i965g: hook up pipe context flush function i965g: add functions to manage shaders i965g: hook up pipe context state functions i965g: hook up pipe context blit functions i965g: hook up pipe context transfer functions i965g: hook up pipe context query functions i965g: add GEN6 GPE i965g: add GEN6 3D context i965g: hook up pipe context 3D functions i965g: add support for timer/occlusion/primitive queries i965g: hook up pipe context video functions i965g: hook up pipe context GPGPU functions i965g: add a toy shader compiler i965g: compile VS and FS with the toy compiler i965g: support the new driver in various targets i965g: add to --with-gallium-drivers It is quite self-contained. If preferred, I can send the patches to the list. Oh, and my account on fdo is disabled because of my own mistake[1]. I contacted some of the developers in the thread but did not get any response. Could anyone help me with that, or how do I have it re-enabled?
