With DRM panic added to trunk, now we only need 3 additional entries for
EFI boot, thus we can just add them and remove the reference to BLFS
UEFI kernel configuration.
This is a conflicting merge because of:
- The trunk and loongarch branch are having two different binutils patch
- The bump of min-kernel in trunk
- The introduce of DRM panic in trunk
Since the previous commit, we've ensured the kernel displaying via DRM
even in the early stage. Now enable DRM_PANIC so the kernel will
correctly show the last lines of the kernel messages in case a panic
happens.
Tested with an incorrect root= line in 3 configurations:
- A QEMU VM booted via BIOS
- A real machine booted via BIOS
- A real machine booted via UEFI
And in all configurations the panic message is correctly dumped.
In 1024x768 we can get 48 lines (twice of 24 lines in VGA console).
Currently on a LFS system booted via legacy BIOS (intead of UEFI), the
users can make two different configurations:
1. The DRM driver for the GPU is built as a module. Then before the
module is loaded (i.e. the root fs is properly mounted) the kernel
messages are displayed via the VGA console.
2. The DRM driver for the GPU is built into the kernel image. Then the
kernel messages are displayed via the DRM-emulated framebuffer
console since a very early stage (before the root fs is properly
mounted).
When the system is booted via UEFI, we use SimpleDRM on the EFI
framebuffer for displaying kernel messages, thus it's always the case 2.
Both are not good for diagnostic in case the root fs cannot be mounted
properly (it's very frequent on lfs-support):
- With 1 the VGA console can only fit 80x24 characters, so the relevent
information is often flushed away.
- With 2 the panic message is often displayed improperly when a DRM
driver is running.
The "DRM panic" feature introduced since Linux 6.11 (but it'll only
become usable for LFS since Linux 6.12) can fix the case 2, while case
1 just cannot be fixed. So start to make LFS booted via legacy BIOS
to use method 2 now, then we can enable DRM panic and fix this
long-standing issue.
Now BLFS documents how to install only the GRUB components missing in
LFS, take the advantage.
Also if efibootmgr is available, it's easier to just run grub-install
w/o the --removable option instead of manually input some nasty
efibootmgr commands.
(cherry picked from commit c6e4dbaee6)
The incompatibilty between systemd and CONFIG_AUDIT has been fixed since
Linux kernel 3.14, thus there is no reason to disable it on LFS. And we
are referring to pam_loginuid.so from /etc/pam.d in BLFS, which is
completely useless if CONFIG_AUDIT is disabled.

Though the commit message mentions "recent Binutils and GCC trunk", I'm
99.99% sure this is only related to Binutils since the troubling
R_LARCH_RELAX/R_LARCH_ALIGN is appearing in some object files assembled
from .S files.
IMO this commit should be backported to even 6.1, but Huacai always
believe people using the latest Binutils should use the latest kernel.
And it seems Linux 6.8 won't catch LFS 12.1 package freeze, leaving me
no choice but backporting this downstream.
"gcc(1)" is really not a file name.
Use <ulink> and link to the online man page on
https://man.archlinux.org/ so the user can refer to the man pages more
easily.
The change is done via a sed command and long lines are wrapped
manually.
- according to our typography, referring to a manual page should be
<filename>page(x)</filename>
- don't enclose punctuation into quotes
- use <option> for option
In Linux 6.6 DRM_FBDEV_EMULATION no longer depends on FB, so we no
longer need to select FB (tested in a QEMU VM).
But if DRM is selected, we must select both DRM_FBDEV_EMULATION and
FRAMEBUFFER_CONSOLE or we'll see only blank screen. And now
FRAMEBUFFER_CONSOLE is not selected by default, be warned!!
