* pvops Dom0 graphics doesnt work with Intel i915 @ 2010-09-29 18:12 sanjay kushwaha 2010-09-29 18:57 ` Jeremy Fitzhardinge 0 siblings, 1 reply; 19+ messages in thread From: sanjay kushwaha @ 2010-09-29 18:12 UTC (permalink / raw) To: xen-devel [-- Attachment #1.1: Type: text/plain, Size: 852 bytes --] Hi Folks, I am trying to boot latest xen-unstable on my laptop which has Intel i915 graphics. PVOPS dom0 is 2.6.33.6 based (from branch xen/stable-2.6.33.x) and the distro is fedora 13 64-bit. The graphics doesnt come up and it seems that i915 driver is crashing multiple times. If I boot in run-level 3 (without X) dom0 boots fine. I tried booting the dom0 kernel with nomodeset and nopat options without any success. I searched on internet and found that multiple people have reported similar problem but I could not find any solution. Has anybody found a solution or workaround to this problem? Thanks, Sanjay PS: I have another laptop with same version of xen and pvops dom0 but it has ATI radeon graphics card. This laptop boots dom0 with graphics when I give nomodeset and nopat options (but fails if I dont give either of those two options).

This time with VT-d. When I enable VT-d on this laptop, graphics again stops working in dom0 with pvops (linux 2.6.32.21). the screen starts showing garbage as soon as it switches into graphics mode.this happens when I boot the pvops kernel both as dom0 and native linux. However, when I try 2.6.33 based pvops kernel (stable-2.6.33.x) graphics seems to work fine with VT-d when running native but it doesnt work when running as Dom0. so now the problem is: with stable-2.6.32.x: graphics works in Dom0 without Vt-d but not with VT-d (neither native nor Dom0). with stable-2.6.33.x: graphics works with VT-d when running native but doesnt work when running as Dom0 (with or without VT-d). I am experiencing this problem both with Lenovo T410, and Dell latitude E6410. Has anybody experienced this problem?
