 Posted: Sun Oct 16, 2016 10:58 am Post subject: [SOLVED] Kernel Firmware Blob Ignored |
 |
|
Hi, I've been battling this for a while now and although not a show stopper, it is getting rather irritating.
So symptoms... Everything works great on first login/reboot/gnome-shell restart, but after a while of use it becomes laggy/framerate drop. If I don't restart gnome-shell at this point, it will cause the system to hang completely. Also, no matter what firmware I configure in the kernel, it ignores it.
Package versions in use:
| Code: | # emerge -av linux-firmware xf86-video-intel gentoo-sources
These are the packages that would be merged, in order:
Calculating dependencies... done!

cdstealer,
The file names listed here are hard wired into the the kernel module, they may change from kernel to kernel.
| Code: | [ 2.419315] i915 0000:00:02.0: loading /lib/firmware/updates/4.8.1-gentoo/i915/skl_dmc_ver1_26.bin failed with error -2

That they exist in /lib/firmware/i915/ is required but not sufficient, since they cannot be loaded from /lib/firmware until root is mounted. The firmware with the exact names the kernel module needed must be included in your kernel binary or the firmware is not available when its needed.
| Code: | | CONFIG_EXTRA_FIRMWARE="i915/skl_dmc_ver1.bin i915/skl_guc_ver1.bin i915/skl_guc_ver4.bin i915/skl_guc_ver6.bin intel-ucode/06-5e-03" |
Fix your CONFIG_EXTRA_FIRMWARE and rebuild and reinstall your kernel.

| You built the driver into kernel, it cannot load the firmware from hard drive at the time of loading. |

DOH! You are quite right.

Though I'm not sure why the GUC is being skipped or if I really need it. I still have the issue with gnome-shell, so time for some more research. I'll close this off as the Gnome3 issue is another matter maybe.
Though, it may also be a bug. As I'm also seeing this in dmesg...

https://bugzilla.kernel.org/show_bug.cgi?id=95461 which also leads to another issue I have https://bugs.freedesktop.org/show_bug.cgi?id=97450
Thanks for your help.

I just noticed this bug and just like you had problems with screen blanking/flickering. Lets hope now with kernel 4.9 it will be gone. So far so good 
On the side note I have noticed my GuC firmware not loading either see " GuC firmware load skipped". Looking at the file description in the website https://01.org/linuxgraphics/intel-linux-graphics-firmwares that one seems important. Any reason it is skipped? My i915 drivers are loaded as modules. Maybe initrd needs some switch on creation? My looks like this
genkernel --no-zfs --no-luks --no-lvm --no-mdadm --no-dmraid --no-btrfs --no-iscsi --no-multipath initramfs

Though I'm not sure why the GUC is being skipped or if I really need it. I still have the issue with gnome-shell, so time for some more research. I'll close this off as the Gnome3 issue is another matter maybe.
Though, it may also be a bug. As I'm also seeing this in dmesg...

https://bugzilla.kernel.org/show_bug.cgi?id=95461 which also leads to another issue I have https://bugs.freedesktop.org/show_bug.cgi?id=97450
Thanks for your help. |
I had the same issue with a recent laptop, the kernel wasn't able to load the firmware for the i915 and iwlwifi/iwlmvm drivers.
Even building the kernel with the firmware blobs included didn't solve the problem.
After building the drivers as modules (instead of built-in) the firmware were loaded properly.... I'll open a bug if I can spend more time on this topic
Tested on Kernel 4.9.2 |

i have been suffering the same problem, with an i5 7200u, if i toggle intel driver as module i have a kernel panic, as disks are not detected.
Could you find any solution? thanks |
