(insert usual question here about readpix demo) Haien, please try readpix, though I know it's troublesome as the machine is in AutoDTI lab.

Please attach the screenshot of readpix, as well as dmidecode output. From the registers, it looks like you've got a single channel of memory and no extra swizzling occurring, and the code at that time should have handled it correctly. dmidecode |grep -A16 "Memory Device$" shows

sorry,this is 915gv, not 915gm. The previous log was wrong Still requires ModeDebug. Created attachment 23952 [details]
xorg.0.log with Modedebug on
(In reply to comment #11) > Still requires ModeDebug. > ok, Xorg.0.log with Modedebug on is re-attached Likely fixed by: commit a243a32388e4828dc5fe8e9dd129a3042bf5b6b3 Author: Eric Anholt <eric@anholt.net> Date: Thu Mar 12 16:27:11 2009 -0700 drm/i915: Change DCC tiling detection case to cover only mobile parts. Later spec investigation has revealed that every 9xx mobile part has had this register in this format. Also, no non-mobile parts have been shown to have this register. So make all mobile use the same code, and all non-mobile use the hack 965 detection. Signed-off-by: Eric Anholt <eric@anholt.net> still fails against this commit.so reopen it. remove from Q1 release blocker 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). this machine is not in our control now, closing. |
