 Posted: Thu Dec 26, 2024 7:26 pm Post subject: EFI Stub, kernel without initrams loads, but black screen |
 |
|
Hi, first time writer 
I am doing a hobby/excercise project building the EFI stub kernel from gentoo-sources for AMD Framework 13, without initramfs/dracut and bootloader.
It is being build on hardened gentoo, without multilib (only 64 bit) and trying to build it opensource.
I have added all the drivers from the gentoo article for Framework 13, also checked it against gentoo-live, and it seems like all the drivers are in place.
But when loading screen freezes with cursor on the top left. I can log in into the system, write dmesg or run lspci, but the screen is stuck as black square with a white cursor.
I can also login using the dist-kernel, built with initramfs and added with efibootmgr.
I attaching my make.conf, dmesg output and lspci output to the message and not sure should I write kernel config here too, or should I upload it and send a link?
kernel config:

dmesg from my kernel:

dmitry131,
Welcome to the Gentoo forums.
The working lspci shows
| Code: | c1:00.0 VGA compatible controller: Advanced Micro Devices, Inc. [AMD/ATI] Phoenix1 (rev c4)
Subsystem: Framework Computer Inc. Device 0006
Kernel modules: amdgpu |
Your one shows
| Code: | c1:00.0 VGA compatible controller: Advanced Micro Devices, Inc. [AMD/ATI] Phoenix1 (rev c4)
Subsystem: Framework Computer Inc. Device 0006 |
I'm not about to download random files from the internet, especially from Google. It's not personal, I'm old and cynical.
Please make friends with wgetpaste to post files and command output.
Educated guess.
amdgpu is the kernel driver for your video card. However it needs to load firmware.
When you configure AMDGPU=y in your kernel, you also need to include the firmware in the kernel binary.
This can be a bit of a moving target as AMD add a file now and again and its not in your list until it fails once more. :)
When you configure AMDGPU=m in your kernel, the firmware will be loaded from /lib/firmware, after the root partition is mounted.
is good. It shows the Vendor and Device IDs, like this ...
| Code: | 0c:00.0 VGA compatible controller [0300]: Advanced Micro Devices, Inc. [AMD/ATI] Navi 22 [Radeon RX 6700/6700 XT/6750 XT / 6800M/6850M XT] [1002:73df] (rev c1)
Subsystem: ASUSTeK Computer Inc. Device [1043:05d7]
Kernel driver in use: amdgpu |
[1002:73df] 1002 means AMD. The 73df identifies the device. That will tell which firmware is required.

1.) You see two lines in your syslog: The first line tells us which parameter the kernel has got form bootloader/bootmanager/UEFI (in your case: UEFI). The second line is the complete kernel command line parameters (=transmitted + BUILTIN). This tells me: You have tried to create an UEFI boot entry with parameter "p1" instead "-p1" (to select the partition) ...and this was even successfull, because if no "-pX" is given the default IS "-p1" ...  Dont worry: Nobody use this "kernel parameter" ... But if you want it clean you can delete the UEFI entry and create a new one.

Thank you pietinger very much for the links! I've built a kernel with amdgpu driver, but without firmware included, so I tried to include different combinations of firmware and it didn't help. So I continued reading the links and foun out I forgot to add the EFI Framebuffer in the kernel 
| Code: |
Device Drivers --->
Graphics support --->
<*> Support for frame buffer devices --->
[*] EFI-based Framebuffer Support
|
While trying I have switched to the newer kernel v6.12.7, so all the entries were very helpfull.
Also, my final addition to include all the firmware:
| Code: |
Device Drivers --->
Generic Driver Options --->
Firmware Loader --->
[*] Firmware loading facility
(amdgpu/gc_11_0_1_mes_2.bin amdgpu/psp_13_0_4_toc.bin amdgpu/gc_11_0_1_pfp.bin amdgpu/vcn_4_0_2.bin amdgpu/gc_11_0_1_mes1.bin amdgpu/psp_13_0_4_ta.bin amdgpu/gc_11_0_1_me.bin amdgpu/gc_11_0_1_rlc.bin mediatek/WIFI_RAM_CODE_MT7922_1.bin mediatek/WIFI_MT7922_patch_mcu_1_1_hdr.bin mediatek/BT_RAM_CODE_MT7922_1_1_hdr.bin) Build named firmware blobs into the kernel binary
|
About "p1": I am writing kernel command line only as "root=PARTUUID=42bebc22-8abc-4775-a431-32e0acbc049c rootfstype=btrfs rootflags=subvol=@ rw crashkernel=64M", but for some reason it is being built with "p1" added to the end, which don't really make sense on btrfs filesystem) |

Your kernel command line is okay ... as I wrote: You have TWO lines in your syslog. The FIRST line shows what the kernel get from OUTSIDE (bootmanager OR UEFI; in your case UEFI). Yes, "p1" comes from your UEFI. The 2nd line shows the complete command line == From outside + built-in command line. (see the first chapter of https://wiki.gentoo.org/wiki/User:Pietinger/Tutorials/Kernel_Commandline_Parameter )
So, just do an: "efibootmgr" OR "efibootmgr -u" (it depends which format it is using for the parameters). Here you will see AS parameter "p1". So, UEFI send/give this parameter to your kernel
My guess was: You have created this (additional/useless) kernel command line parameter when you had created the UEFI entry ... and my guess is: You tried to inform "efibootmgr -c ..." that the first partition is the ESP ... but instead -p1 you had typed p1 ... because without the minus-sign it is not a parameter, efibootmgr created your UEFI entry WITH this kernel command line parameter "p1" (and because efibootmgr miss the -p parameter it take -p1 as default). (an example you can see here: https://wiki.gentoo.org/wiki/User:Pietinger/Tutorials/Boot_kernel_via_UEFI#Create_the_necessary_UEFI_entries )
But, as I said, this does not harm because this kernel command line parameter does not exist ... and so kernel says: "Unknown kernel command line parameters "p1", will be passed to user space."
... and because there is no initramfs which would check this parameter, nobody cares about it ... it's just a "beauty mistake"
