Add HW context support to i915 driver
Starting with Gen6 (Sandy Bridge), Mesa 9.2+ relies on hardware context switching in the i915 driver.
The code is in HEAD and stable/10 and a merge to stale/9 is pending.
See Graphics for further informations.
How to test
We're insterested in test reports (success or failure) on any GPU (even non-Intel).
Install Mesa 10.3 from the "experimental" branch of the xorg-dev repository. You need to rebuild at least the following ports:
Check if Mesa complains about missing hw context:
# glxinfo name of display: :0.0 Gen6+ requires Kernel 3.6 or later. Assertion failed: (ctx->Version > 0), function handle_first_current, file ../../src/mesa/main/context.c, line 1498. Abort (core dumped)
- Clone the Git branch or apply the patch to your local source tree
- Build and install kernel
# glxinfo name of display: :0 display: :0 screen: 0 direct rendering: Yes ... OpenGL renderer string: Mesa DRI Intel(R) 965GM OpenGL version string: 2.1 Mesa 10.2.4 ...
- Play with your usual GL applications.
Please report any success or failure by following the instructions on the Graphics portal.
