[Nouveau] [Bug 78441] New: X does not start under kernel 3.13.x
https://bugs.freedesktop.org/show_bug.cgi?id=78441 Priority: medium Bug ID: 78441 Assignee: nouveau at lists.freedesktop.org Summary: X does not start under kernel 3.13.x QA Contact: xorg-team at lists.x.org Severity: normal Classification: Unclassified OS: Linux (All) Reporter: aebenjam at opentext.com Hardware: x86 (IA32) Status: NEW Version: unspecified Component: Driver/nouveau Product: xorg Created attachment 98691 --> https://bugs.freedesktop.org/attachment.cgi?id=98691&action=edit output from dmesg with buffer set to 1M X starts just fine under 3.12.x for me, but fails under 3.13.x. I waited for a few versions to see if the problem would be found/fixed by others, but we're now up to 3.13.11 (under Fedora 19) and it still fails. Booting back into 3.12.11 works fine. Forgive me if more information (beyond the kernel log and Xorg.0.log) would be helpful... I'm fairly green at working at this level of the O/S. Please ask for whatever you need. lspci shows the graphics card as "NVIDIA Corporation G86 [Quadro NVS 290] (rev a1)" and the kernel log repors "Chipset: G72 (NV46)", "Family : NV40". Again, please let me know if I can provide more useful diagnostic info. Oh, and at time index 638.685456 of the kernel log I had started switching to alt-consoles. Until that point there were no additional log messages generated.

[Nouveau] [Bug 78441] X does not start under kernel 3.13.x
https://bugs.freedesktop.org/show_bug.cgi?id=78441 --- Comment #2 from Ilia Mirkin <imirkin at alum.mit.edu> --- There does not appear to be any indication of a G86 card in your computer. PCI ID 10de:01d7 corresponds to G72 [Quadro NVS 110M / GeForce Go 7300] according to http://envytools.readthedocs.org/en/latest/pciid.html. And we read that it's a NV46 ( = G72) from the card's mmio register 0, further confirming that it's a G72... Can you provide the output of "lspci -nn"? The only relevant change between 3.12 and 3.13 that I can think of is that we added support for MSI. You can try disabling it by adding nouveau.config=NvMSI=0 to your kernel commandline. If that doesn't help, you'll have to do a bisect. -- You are receiving this mail because: You are the assignee for the bug. -------------- next part -------------- An HTML attachment was scrubbed...

No idea what a > "bisect" is. Please advise...git bisect. Grab a clone of the tree, and use git bisect between the good and bad tags (v3.12 and v3.13) to identify the offending commit. You can probably restrict the bisect to drivers/gpu/drm/nouveau. IOW, you can run git bisect start v3.13 v3.12 -- drivers/gpu/drm/nouveau There are more detailed online guides that show how to use git bisect, and you may even find something that's specific to your distro if you're not familiar with building kernels. Unrelated to this, your lspci shows no indication of a G86. Are you sure you saw that on the same computer? -- You are receiving this mail because: You are the assignee for the bug. -------------- next part -------------- An HTML attachment was scrubbed...

https://bugs.freedesktop.org/show_bug.cgi?id=78441 --- Comment #6 from aebenjam at opentext.com --- Gah, very sorry - the G86 is from my desktop. (Read: I'm an idiot.) The laptop, obviously, shows: "01:00.0 VGA compatible controller: NVIDIA Corporation G72M [Quadro NVS 110M/GeForce Go 7300] (rev a1)" Very sorry for the red herring... I'll try to find time to try a git bisect, but my experience with compiling linux kernels directly dates back to 2.4.x, if not prior, and really I'm a bit lost at that level. ie. I might spend a lot of time with very little to show for it. I'm open to suggestions... and thanks again for the attention. -- You are receiving this mail because: You are the assignee for the bug. -------------- next part -------------- An HTML attachment was scrubbed...

https://bugs.freedesktop.org/show_bug.cgi?id=78441 --- Comment #7 from aebenjam at opentext.com --- Not sure that it's helpful, but I tried with the latest kernel (provided by Fedora 19 - 3.14.4-100.fc19.i686) and it still failed to start the X session. I noticed, on the console while shutting down, that I was seeing messages: E[Xorg[609]] failed to idle channel 0xcccc0001 [Xorg[609]] E[Xorg[609]] failed to idle channel 0xcccc0000 [Xorg[609]] Not sure if that's useful to indicate what's going on. It also took awhile for it to finally shut down. But, flipped back to 3.12.11-201.fc19.i686 and I'm up and running fine.

This is not the sort of thing that'll just fix itself... a bisect would probably identify the offending commit, which would probably be enough to figure out what the issue is. I scanned through all the nouveau commits between 3.12 and 3.13, and nothing jumped out as possibly causing this, but a lot of times there are completely unintended effects. -- You are receiving this mail because: You are the assignee for the bug. -------------- next part -------------- An HTML attachment was scrubbed...

https://bugs.freedesktop.org/show_bug.cgi?id=78441 --- Comment #9 from aebenjam at opentext.com --- So, I'm not sure about doing a bisect, but you can download the source RPMs for the two versions kernel-3.12.11-201.fc19 and kernel-3.13.4-100.fc19 which Red Hat released, here: http://koji.fedoraproject.org/koji/buildinfo?buildID=498402 and http://koji.fedoraproject.org/koji/buildinfo?buildID=499637 You can download the .src.rpm easily and then diff the nouveau trees. I can attach that diff if you like. Thing is I'm not enough of a developer to (easily) take that any further. I'm happy to help, but otherwise I'm an IT geek and out of my depth trying to work on video drivers. Sorry. Let me know if I can assist further. Otherwise, for the moment, I'm stuck on a 3.12.x kernel. :( Adam -- You are receiving this mail because: You are the assignee for the bug. -------------- next part -------------- An HTML attachment was scrubbed...

https://bugs.freedesktop.org/show_bug.cgi?id=78441 --- Comment #13 from aebenjam at opentext.com --- It's like the kernel hates me and is trying to make a liar of me. I *know* I tried it before and it didn't work - but it's totally doing the job now. Booted up just fine. Only thing I can think of is that it's a slightly newer kernel since my previous test... although I'm guessing you're going to tell me nothing changed. Anyway, confirmed as working properly under 3.14.4-100.fc19.i686 with nouveau.config=NvMSI=0 Thank you very much for your help. What is it I've just disabled?

Support for using MSI on nvidia cards was added in kernel 3.13, which was why I had suggested trying to disable it. I guess the rearm register must be somewhere else, or something extra needs to be done... OTOH, it's very interesting that you bisected it to that particular commit. It's not the commit that turns on MSI, but rather a commit that fixes MSI for some situations, making it more reliable.
