[Intel-gfx] Strange performance cliff...

2010-10-12 Thread Peter Clifton
Using glxgears as a tool to exercise the GPU with some simple rendering, I have noted a strange cliff in the intel_gpu_top output when resizing the glxgears window: Below a certain size e.g.: -geometry 576x868+0+29 core clock: 400 Mhz render busy: 21%: ▎

[Intel-gfx] [PATCH] drm/i915: new blitter ring support from Sandybridge

2010-10-12 Thread Zhenyu Wang
This adds new ring for blitter engine starting from Sandybridge. Patch is against 2.6.36-rc kernel. As I haven't been able to find out all regressions on drm-intel-next yet, which made KMS totally fail on SNB now. I just base on current upstream tip, so I can see the testing result. Signed-off-by
