Then I got an Ivy Bridge laptop and was busy enabling GEN7 on the driver until now. I force-updated the branch for the latest code, and cleaned the history up today. The branch has 24 commits on top of master Chia-I Wu (24): 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: 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 GEN7 GPE i965g: add 3D pipeline for GEN6 i965g: add GEN7 support for 3D pipeline i965g: hook up pipe context 3D functions i965g: add support for time/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/GS/FS with the toy compiler i965g: add the driver to the build system If you are interested in the complete history, you can take a look at i965g-next branch. Changes since the announcement are: - GEN7 support (stencil buffer support is still missing) - fixed tons of bugs, with piglit passing 7999 of 8428 tests The state of the TGSI->GEN compiler remains the same: messy, missing some features, and non-optimizing. As my focus is still on features, the performance should remain about the same. I will see if I can improve the situations over the next few months. If there is no objection, I'd like to merge it in a day or two. > The driver is written from scratch. However, it follows classic i965 > driver for many of the design decisions.
