Dear Poma,
Don't get anyone wrong, your input is greatly valued. 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. Thanks! Yours,

Are you saying Fedora kernels aren't valid for testing purposes!? Madre mía!
Moreover, this regression is not just for my device. Apart from Ben, in "Red Fedora" there are several skilled kernel developers. Why they do not help!? Everything is on the user's back, really?

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!

Are you saying Fedora kernels aren't valid for testing purposes!?
No, that's not what I'm saying. You used a Fedora kernel which is fairly recent and found a bug. However, they're less useful for pinpointing your problem to the offending bit of code, as you demonstrate below.
Madre mía!
Salud...
Moreover, this regression is not just for my device. Apart from Ben, in "Red Fedora" there are several skilled kernel developers. Why they do not help!? Everything is on the user's back, really?

This is precisely why 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.

Dear Poma,
Don't get anyone wrong, your input is greatly valued. 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. Thanks! Yours,
Roy
Are you saying Fedora kernels aren't valid for testing purposes!?
No, that's not what I'm saying. You used a Fedora kernel which is fairly recent and found a bug. However, they're less useful for pinpointing your problem to the offending bit of code, as you demonstrate below.
Madre mía!
Salud...
Moreover, this regression is not just for my device. Apart from Ben, in "Red Fedora" there are several skilled kernel developers. Why they do not help!? Everything is on the user's back, really?

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.

You guys were in at least right in one, in this particular case Fedora kernel is unusable. . .. ... Tested with vanilla...

Ben, any ideas? Poma, can you attach your vbios to the bug above?

Thanks! 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). [Don't use such kernels for anything other than debugging, setting the debug level so high adds a ton of code and will slow things down significantly.]

In 415f12e proximity no kernel is useful, resumed machine is stuck. "The display remains OFF" meaning everything else works(likely to Daredevil), only applies to recent kernels.
