Are you sure? It only states "does not apply to firmware images that are built into the kernel image". I don't have "compress-*" USE flags for sys-kernel/linux-firmware, so I was embedding uncompressed firmware in the kernel, which was loading fine on a few PCs for years. Here's an example from one PC with the exact same kernel (+ CONFIG_FW_LOADER_COMPRESS):
| Code: |
$ sudo dmesg | grep -i firmware

But to do the due diligence I've tried without
| Code: | /usr/src/linux # grep CONFIG_FW_LOADER_COMPRESS .config
# CONFIG_FW_LOADER_COMPRESS is not set
|
Same effect, stuck on

Come on man, you are the only one trying to help here, I'm very thankful. You don't need to apologize for anything.
Could you share your moduleless config? Maybe it'll work for me and I can go from there. |

This is my current config for a i9-13900K on a Gigabyte Z790 Aorus Elite AX
(see also: https://wiki.gentoo.org/wiki/User:Pietinger/temp/delete_me )
http://0x0.st/XOxm.10.2
It will not work for you because:
- wrong kernel command line parameters (NEVER boot with IMA enforce without having necessary files); you will need: ima_appraise=off
- only an "old" i915
- firmware files are different to yours
- other ethernet
- it is a hardened configuration WITHOUT 32bit support (== I am using a No-Multilib profile)
- I dont use a boot manager => I am booting it directly from UEFI (therefore efistub is necessary)
- I dont use an initramfs
- It is for OpenRC (no systemd)
- no modules support, no WLAN, no bluetooth, no IPv6, no CD-ROM support, no serial, no virtualization (slim kernel)
- my root partition is an EXT4 (bcachefs only for testing)

Thank you for your kind words ! 
I just had a very crazy thought ... i don't know if there is a limit to the number of firmware files you can include ... what if you throw out all the unneeded ones and only include the microcode for your cpu AND the firmware files for your gpu ?

manwe_,
have you made any new discoveries?
Did my kernel configuration help you in any way (probably not, right) ?

OK, so had an hour to play with your config. Few changes I've made:
- removed CONFIG_CMDLINE
- added support for initramfs and my .cpio
- added 4 files that i915 was trying to load: i915/mtl_dmc.bin i915/mtl_guc_70.bin i915/mtl_huc_gsc.bin i915/mtl_gsc_1.bin (https://postimg.cc/SjzXtMtk)
After this, I have two outcomes.
With "i915.enable_guc=2 i915.enable_psr=0" freeze: https://postimg.cc/5YQtGhgn
Without it display works, kernel goes into initramfs but there are some complains about "missing mei component" and "GSC proxy handler failed to init" whatever that is: https://postimg.cc/phj2kDVS
-- update:
OK, GSC proxy was because of missing CONFIG_INTEL_MEI_GSC_PROXY. After that there are no errors with "i915": https://postimg.cc/pm0zttQH
But still freeze with enable_guc=2/enable_psr=0.
Tomorrow I'll try to further modify that config, add luks/cryptsetup support to boot beyond initramfs and check if Xorg works. |

First of all, thanks for the feedback; if i understood correctly, the graphic now works if you don't set any "evil" (enable_guc=2/enable_psr=0) command line parameters, yes ?

| So far works in console mode (initramfs). As soon as I have free hour I'll have to modify your kernel further to be able to boot my system and check X. |

OK, after few more changes like device mapper, crypt, xfs I was able to boot system. Unfortunately Xorg doesn't work.
Xorg.0.log for user uid=1000: https://bpa.st/DAEA
Xorg.0.log for root: https://bpa.st/BH3A
Xorg starts and stays running together with window manager process, but screen is black. Looks line those lines seem to be the problem
| Code: | [ 119.470] (EE) intel(0): Failed to allocate caches, disabling RENDER acceleration
[ 119.775] (EE) intel(0): Failed to submit rendering commands (Cannot allocate memory), disabling acceleration.
|
But so far I wasn't able to find any solution. First error comes from this function of xf86-intel-video: https://gitlab.freedesktop.org/xorg/driver/xf86-video-intel/-/blob/master/src/sna/sna_accel.c#L18277

Oh no ... please dont use this outdated driver for your most modern GPU 
What happens if you move every file from /etc/X11/xorg.conf.d/ to a backup place and restart X11 again ?
Those were my steps for my GPU of i9:
| Code: | # in make.conf => VIDEO_CARDS="intel"
# emerge -pv xorg-server
# cd /etc/X11
# mkdir xorg.conf.d
# cd xorg.conf.d
# cp /usr/share/X11/xorg.conf.d/40-libinput.conf .
# nano -w 40-libinput.conf
! Add to keyboard section => Option "xkb_layout" "de" |
Nothing else !!! (After this I emerged directly plasma-meta and kdecore-meta)
If you want you might emerge libva-intel-media-driver also if you use "vaapi"
No installation of https://wiki.gentoo.org/wiki/Intel#Intel_DDX !!
(No old and outdated VIDEO_CARDS="intel i915" or VIDEO_CARDS="intel i965")

I also don't use xorg.conf.d files for anything besides keyboard.
To be honest somehow I've missed whole transition from i915 X drivers. Eveyrthing was working fine for 9th and 13th gen Intel. Nevertheless, I've removed xf86-intel-video and not only 9th gen booted fine, but also T14 Gen5 showed X Thank you so much for your help. Can I buy you a coffee or currywurst for your help?
Now all I have to do is figure out what's wrong with my kernel, mix it with your config and find drivers for other hardware that is not working right now (wifi, touchpad, …). But that should be easy now when I have system booting fine into X.
If anyone with T14 Gen5 happens to read this thread, here's config that boots and show X: https://paste.gentoo.zip/w8zcFzYS |

You are very Welcome !
It is precisely this feedback that is so valuable.
| manwe_ wrote: | | [...] Can I buy you a coffee or currywurst for your help? |
That's very kind of you, but do you know how you can give back the most to the Gentoo community ? Do the same as I do with many others:
Help here where you can ... because we all get older (although Neddy is a bit older than me  ) and have to stop at some point ... then we need people to follow us ... especially people who have a good Linux and Gentoo knowledge... like you. I help here because I used to get help ... and now, as an old man, I want to give it back.
Have a good time ... and fun with Gentoo.
