Hawaii Bug-Fixes Start Hitting Mainline RadeonSI Gallium3D

For those excited about the recent working Radeon R9 290 "Hawaii" Gallium3D support, a number of bug-fixes were committed in recent hours to Mesa for bettering the support for those wishing to use this open-source AMD Linux driver for their ultra high-end graphics hardware.

Open-source AMD Linux users wishing to use a Hawaii GPU will still need to utilize the patches that will not be queued up until the Linux 3.17 kernel (along with updating their Radeon microcode files) but the RadeonSI Gallium3D Mesa improvements are starting to hit the mainline tree.

Marek Olšák made a few commits on Monday to fix-up the user-space Gallium3D driver for R9 290 "Hawaii" hardware with:

- Fixing occlusion queries.
- Fixing vRAM size overflows.
- A Stream-Out hang fix.
- An instancing hang fix.
- Fixed CMASK and HTILE calculations.
- Other Hawaii-related RadeonSI fixes.

As soon as Linux 3.17 development begins when we can start testing the mainline tree to ease testing and reproducibility of the results, we'll be running some AMD Radeon R9 290 Linux graphics benchmarks on Linux 3.17 + Mesa 10.3 to see how the performance compares to the AMD Catalyst graphics driver. Aside from Hawaii, coming up in the next few days are also some new Radeon HD 6000/7000 + Rx 200 series driver benchmarks.
