I think you should file a bug against the nouveau driver on
bugs.freedesktop.org (xorg -> driver -> nouveau).
Yes, I'll do so when I have figured out how to apply the patch to
the nouveau driver from freedesktop.org. The patch is *againsts the
kernel source*, like: --- a/drivers/gpu/drm/nouveau/core/... +++
b/drivers/gpu/drm/nouveau/core/... but the structure of the driver
from git is: nouveau/drm/core/... (sorry for being so clueless, but
I never dealt with kernel modules ...)
Check rhbz #1121331, recent comments.
Thank you for your detailed instructions on bugzilla, they were easy to
follow - but on reboot, the gpu fan began to roar like before, although
no errors occurred during the process of building and installing the
nouveau module:
1. The nouveau source from git got patched by your patchfile in exactly
the same way as the kernel source tree got patched by "my" patchfile.
The four respective files were identical.
2. The make process of the nouveau module finished without error, I
copied nouveau.ko to
/lib/modules/3.17.6-300.fc21.x86_64/updates/
3. After depmod, modinfo -n showed the appropriate location of the
module:
/lib/modules/3.17.6-300.fc21.x86_64/updates/nouveau.ko
So I really can't figure out what happened, I repeated the process of
rebuilding the complete kernel tree and got a quiet fan again ...
There is even more magic: I repeated the proposed build process of the
patched nouveau driver after an update to the most recent kernel
(3.17.7-300) - result again: a noisy fan.
Than (after booting into a different kernel) I removed
kernel-3.17.7-300.fc21.x86_64 (and the corresponding kernel-core and
kernel-modules), this, btw., left /lib/modules/3.17.7-300.fc21.x86_64/
untouched, including the module binary nouveau.ko.
Next step was an update to kernel-3.17.7-300.fc21.x86_64 again, and
after booting into it, the fan was silent! modinfo -n nouveau says:
/lib/modules/3.17.7-300.fc21.x86_64/updates/nouveau.ko,
which is the binary that had survived the erasure of 3.17.7-300.
I really have no idea about the way modules get installed during a
kernel update, but there seems to be something more than a "simple"
depmod command that I gave after the initial modules build.
Oh, yeah. Forgot. I suspect you'll need to rebuild the initramfs after
patching your driver. The "depmod" verifies that all the module
dependencies were met so if you were to "modprobe" nouveau it'd work,
but I believe nouveau goes into the initramfs so the boot was still
using the original one from the kernel update. So:
1. Patch
2. Build
3. Move to appropriate spot
4. Depmod
5. Rebuild initramfs...make sure the new module is included
6. Reboot
