[Xen-devel] pvops Dom0 graphics doesnt work with Intel i915
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). _______________________________________________ Xen-devel mailing list Xen-devel@lists.xensource.com http://lists.xensource.com/xen-devel

Hi Jeremy, I switched to stable-2.6.32.x branch (which is 2.6.32.21 based) but I get the same problem. Attached is the Xorg.0.log file when I booted with nomodeset option. interestingly I did not see any kernel or driver crash messages in the dmesg output. I do see these messages multiple times in /var/log/messages * Sep 29 15:40:32 vwifi0 gdm-binary[2244]: WARNING: GdmDisplay: display lasted 0.048984 seconds Sep 29 15:40:32 vwifi0 gdm-binary[2244]: WARNING: GdmLocalDisplayFactory: maximum number of X display failures reached: check X server log for errors* Thanks, Sanjay On Wed, Sep 29, 2010 at 11:57 AM, Jeremy Fitzhardinge <jeremy@goop.org>wrote:> On 09/29/2010 11:12 AM, sanjay kushwaha wrote: > > Hi Folks, > > I am trying to boot latest xen-unstable on my laptop which has Intel > > i915 graphics.

Re: [Xen-devel] pvops Dom0 graphics doesnt work with Intel i915
When I dont use nomodeset option, dom0 boots fine X runs properly. So Fedora 13 (X86_64) distro with stable-2.6.32.x pvops kernel and xen-unstable works fine for i915 without nomodeset option.

Re: [Xen-devel] pvops Dom0 graphics doesnt work with Intel i915
Hi, I have run into more problems now. 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?

Re: [Xen-devel] pvops Dom0 graphics doesnt work with Intel i915
Hi Konrad, I tried your tree. It created a 2.6.32.15 based pvops kernel but graphics with VT-d still doesn''t work. when I give iommu=0 on xen kernel command line in grub menu, graphics works but with iommu=1 it doesnt work (The whole screen is garbage).

Re: [Xen-devel] pvops Dom0 graphics doesnt work with Intel i915
Hi Konrad, Unfortunately T410 doesnt have a serial port and neither does the docking station. I havent had any success with USB-to-Serial port dongles in the past. is there any way to get the serial port output?

RE: [Xen-devel] pvops Dom0 graphics doesnt work with Intel i915
Sanjay, Have you tried the latest xen-unstable staging tree? It has a workaround for T410 VT-d graphics issue caused by Lenovo BIOS. This might be the workaround you need: http://xenbits.xensource.com/staging/xen-unstable.hg?rev/4beee5779122 Allen From: xen-devel-bounces@lists.xensource.com [mailto:xen-devel-bounces@lists.xensource.com] On Behalf Of sanjay kushwaha Sent: Thursday, October 07, 2010 12:13 PM To: Konrad Rzeszutek Wilk Cc: Jeremy Fitzhardinge; xen-devel Subject: Re: [Xen-devel] pvops Dom0 graphics doesnt work with Intel i915 Hi Konrad, Unfortunately T410 doesnt have a serial port and neither does the docking station.

Re: [Xen-devel] pvops Dom0 graphics doesnt work with Intel i915
Hi Allen, So this may not be the correct forum to ask this question but I am wondering if a similar workaround has been developed for VT-d in Linux kernel for this problem. I am trying to boot pvops Linux as Native Linux (2.6.32.21) with VT-d on Lenovo T410 and Intel graphics is not working. Can someone please let me know?

RE: [Xen-devel] pvops Dom0 graphics doesnt work with Intel i915
Hi Sanjay, The fix in Xen was derived from a similar fix in Linux kernel below. It is already part of the latest Linux kernel. Since it was checked in August, it is not in 2.6.32.21 pvops kernel you are using. https://patchwork.kernel.org/patch/132771/ Allen From: sanjay kushwaha [mailto:sanjay.kushwaha@gmail.com] Sent: Saturday, November 06, 2010 10:22 AM To: Kay, Allen M Cc: Konrad Rzeszutek Wilk; Jeremy Fitzhardinge; xen-devel Subject: Re: [Xen-devel] pvops Dom0 graphics doesnt work with Intel i915 Hi Allen, So this may not be the correct forum to ask this question but I am wondering if a similar workaround has been developed for VT-d in Linux kernel for this problem. I am trying to boot pvops Linux as Native Linux (2.6.32.21) with VT-d on Lenovo T410 and Intel graphics is not working. Can someone please let me know?

Re: [Xen-devel] pvops Dom0 graphics doesnt work with Intel i915
Thanks Allen, Looking at this patch, I realized that I dont need the patch. using intel_iommu=igfx_off on kernel command line gets the same job done in this kernel.
