 Posted: Wed Apr 18, 2018 3:22 pm Post subject: [Solved] Recent removal of Firmware tree from Kernel |
 |
|
Hi, I'm having a problem compiling the Kernel (4.15.13) and research suggests it's related to the following:
https://bugs.gentoo.org/637698
https://forums.gentoo.org/viewtopic-p-8158204.html?sid=92260392d92ef1718e20b97bad7e960c
However, I do not get that error about "* ERROR: Failed to compile the "firmware_install" target..."
I don't use GenKernel, but I do get the previous one:
| Quote: | ld: arch/x86/boot/compressed/head_64.o: warning: relocation in readonly section `.head.text'
ld: warning: creating a DT_TEXTREL in a shared object. |
I was following the AMDGPU installation (and I've done it successfully before it was AMDGPU, flgx I think).
According to [1], it is removed from the tree. But I assume this is just to get the firmware (now through the linux-firmware package).
On the other hand, if this means menuconfig won't have the option anymore, how is the procedure now since the card requires the firmware?
Would a simple make mrproper solve it?
Regards.

I am. I configure manually and compile it in. (like I did in the past)
Another possible solution is to fallback to the "stable" Gentoo Sources 4.9.76-r1 (it is before that 4.14 when they seem to have removed it)
But before I tried it, the kernel booted normally.
Edit: Also, I cannot check dmesg cause the kernel Panics on boot. Trying to access the logs from this installation seem to suggest it's not being logged (which file should I check? They all seem old, from the time the kernel booted normally.. that is, before I inserted the firmware) |

If the kernel panics, nothing will be written to local logs. You will need to record the message off the screen (pencil&paper, cellphone camera, serial console, netconsole, etc.) if you want to keep it past when you manually hard reset the system.
While I cannot be sure without more context, the cited warning seems unrelated to the firmware removal and unrelated to the panic. |

The wiki entry contains details on how to deal with the amdgpu firmware.

Thanks all. The issue is solved, details FYI follow:
| Quote: | | I do not believe the panic is firmware related. Generally all cards should work without as VGA devices, adding firmware enables advanced features. |
Indeed, it seems I went too far when disabling support for old P/ATA disks.  Although, adding firmware (or conflicting fb drivers) can, at least, make everything blank. (as per the following thread)
The problem was pretty much the same as described here:
https://forums.gentoo.org/viewtopic-t-941030-view-next.html
My mistake was the same as the 2nd to last post there, except I thought the fbdev legacy emulation was needed only for X. 
Once again, thanks for the prompt assistance.
Edit: The Kernel compilation warning does persist however:
| Quote: | ld: arch/x86/boot/compressed/head_64.o: warning: relocation in readonly section `.head.text'
ld: warning: creating a DT_TEXTREL in a shared object. |
