Actually I have nothing to show cause logs are all OK.
Haha, it seems to me that the bugs become intelligent.

Logs(dmesg) are literally identical.
3.15.10-201.fc20.x86_64 - nouveau(fb) resume & thaw PASSED, and that's all what works.
Kernels >= 3.16 - nouveau(fb) resume & thaw BROKEN
ALL Kernels - vesa(fb) resume & thaw BROKEN.
Have a nice weekend folks.

First Fedora Kernel with broken video resume/thaw aka FFKWBVRT i.e. kernel-3.16.0-0.rc0.git10.1.fc21 comes with 'patch-3.15-git10.xz' which closely resembles "git/commit/drivers/gpu/drm/nouveau?id=7a014a". Simple as that. Why are you asking me that bisect formality, man is it not enough that I tested two dozen kernels. poma ^ permalink raw reply [flat|nested] 16+ messages in thread

The reason why "we" (nouveau developers) generally ask for a git bisection is because we don't know or track specific distributions. Although your search has narrowed the problem down (thanks for that!), we don't know how big the difference is between kernel-3.16.0-0.rc0.git9.1.fc21 and kernel-3.16.0-0.rc0.git10.1.fc21. Is the difference literally just that one patch? Or were there more patches to nouveau or drm that might have been the culprit? So far I haven't succeeded in finding the exact differences between the two kernels. Git bisect on the upstream kernel on the other hand will always point at the precise patch that broke the kernel, narrowing down the search space of the bug for developers thus reducing the time it takes to fix your issue. Unless developers can reproduce your issue, Unfortunately the user is the person who has to do the bisecting. So in short: narrowing down the search space often saves a lot of time of the developer, reducing the time it takes to fix your issue! Thus, if you can find the time to perform a git bisect (with the right good/bad markers it really should not take that many kernels to build), or if you can validate that the patch you mention *really* is the only difference between the two kernels, it'd be greatly appreciated.

the user is often asked to perform a git bisect. There's a mountain of files touched between the two Fedora kernels (xzgrep output), corresponding witk something like 20 patches. Any of those could be the offender. We don't know, and now the search space still is 20 patches. Git bisect is nothing more than taking a kernel, marking a good and a bad kernel in terms of patches in the git history (like you requested below), and compiling and testing a few. Git makes sure that every kernel you try roughly halves the search space, so you'll have the offender in 5 steps. It's not that we hate you and want you to suffer on complex procedures preferably including kernel compiles, but this process just gives more precise information to the developers... and I bet it takes less time than trying random kernels from Koji to narrow down the search space. Anyway, we're not forcing you to do a bisect. If you don't, that's fine, but it probably takes longer to find the specific bug. We'd be grateful if you do though, as it'll save a lot of time from the hard-working developers that rather want to focus their attention on problems like reclocking and getting the latest generations of cards to work. > http://git.linuxtv.org/cgit.cgi/media_build.git > Whether the nouveau project has something like this? We do, it's right here: http://cgit.freedesktop.org/nouveau/linux-2.6/log/?h=linux-3.16 . Problem is that it's not aligned with distributions' kernels, so it doesn't tell you a lot. To come back to putting all the burden on the user: bugs don't always trigger for everyone. I've never seen this bug before. Most often it's a software error that only hits on one or several video cards in very specific configurations (like dual monitor, specific output port, optimus, VRAM), and developers don't always have this configuration available for testing. If developers can't reproduce and they don't know where to look, they're not going to be able to fix a bug. Roy > poma > ^ permalink raw reply [flat|nested] 16+ messages in thread

If possible, please provide kernel logs (which include the initial boot and the resume) for both 415f12efc1 and 415f12efc1^ (i.e. parent commit). Please boot those kernels with 'nouveau.debug=trace,PDISP=spam' so that we get the maximal debug info. In order for that to work, you'll need to change CONFIG_NOUVEAU_DEBUG to 7 (spam).

Doing a bisect would involve half as many kernels... Knowing the exact commit that breaks things is a fairly useful debug tactic, and drastically increases the chances that a problem gets fixed. Not sure why you're referring to it as a formality. git bisect start v3.16-rc1 v3.15 -- drivers/gpu/drm/nouveau (Pro tip: use a config tailored to your machine rather than a distro config if you want to spend 5 min/compile instead of 1 hour/compile) Or you can wait and hope that someone else will have the same problem and works out the commit that causes it. Or you can see if it has already been fixed in the latest kernels. Or try the experimental repo at http://cgit.freedesktop.org/~darktama/nouveau/ (a bit of a pain to build, unfortunately, you need some unknown kernel version to build against, usually ~latest works).
