working fine here on dual-channel g45. (In reply to comment #2) > working fine here on dual-channel g45. > Yes, but now the issue is: if one is 1G and the other is 512MB, readpix fails with tiling on . We try this with any combination of two memory slots. Our q965 does not has this issue, it may be g45 issue only. This issue still eixsts with current build. commit 7c8bed62e0165a0be3363f7abf81bf9e30341e00 Author: Eric Anholt <eric@anholt.net> Date: Fri Oct 30 15:33:11 2009 -0700 intel: Use GTT mapping when available for swrast. This improves piglit quick.tests runtime from 19:33 minutes to 6:06 on my GM45. It should also hide most of the A17 swizzling issues, though they'll still exist when swapping occurs (which is the kernel's problem either way) It still fails with commit 7c8bed62e0165a0be3363f7abf81bf9e30341e00. But it is verified with recent driver. Following is these commits: Libdrm: (master)b0b96636dbf93445dd532b09b21fa4fc5ce6bdc7 Mesa: (master)1cc16e1b831cef8e1573cc998cee3e55179bb830 Xserver: (master)d30637339963950910e5f5fb755b8465ac7dddb4 Xf86_video_intel: (master)10946118dd3a63f1375a1bfde0b2f0542a93c1c2 |
