Others paramaters defined per board default setting with coreboot.save_oldconfig_in_place helper
both linux/coreboot:
- save_in_defconfig_format_in_place : takes whatever coreboot config file for a make BOARD=xyz statement and saves it in defconfig
- save_in_oldefconfig_format_in_place : takes whatever coreboot config file for a make BOARD=xyz statement and saves it in oldefconfig
linux:
- linux.prompt_for_new_config_options_for_kernel_version_bump:
- The most useful helper as of now when doing kernel version bump.
- Requires to save current kernel config in oldconfig (make BOARD=xyz linux.save_in_oldefconfig_format_in_place) first, then bump kernel version in board config and then use that helper to review new options and save in tree.
- add additional kernel boot params for i915 where needed:
- adds : drm_kms_helper.drm_leak_fbdev_smem=1 i915.enable_fbc=0 ( to permit kexec into vesa fb of kexec'ed kernel for i915 driven gpus without framebuffer compression, leaking smem fbdev address for kexec to pickup )
advanced qemu-coreboot-*-tpm*-* boards enables virtio qemu/kvm through command line option.
qemu-coreboot-* (whiptail or fbwhiptail) basic boards are using bochs gpu emulation, provided through qemu
linux-qemu.config, if shared as of now, needs to provide both virtio (no need of FB_SIMPLE because DRM) and BOCHS+SIMPLE_FB
It was impossible to use directly 4.14 defconfig and apply it to 5.10.
Saving 4.14 in oldconfig, then editing in 5.10 was necessary.
- E1000E module (as kernel module support...) was lost in conversion and needed to be added back.
Also tuned things up:
- legacy-flash has no RETPOLINE, no security policy at all. Has expected usb controllers modules, exFAT and bare minimal support for flashrom.
- IMPORTANT: CONFIG_X86_IOPL_IOPERM kernel option is required by flashrom
- legacy adds sata, retpoline, additional modules (ethernet), security policy related material on top of legacy-flash config
- maximized adds MMC card support, mousedev+synaptic (to report presence through oem-system-info-xx30), thin provisioning+snapshot support
- tuned with linux.prompt_for_new_config_options_for_kernel_version_bump
Current storage format is oldconfig from now on for proper analysis. If needed, once can save back in defconfig prior of bumping to newer version.
Use CONFIG_BRAND_NAME to control the brand name displayed in the UI.
Override by setting BRAND_NAME when building, either in the Makefile or

Debian 12's initrd by default now consists of an uncompressed cpio
archive containing microcode, followed by a zstd-compressed cpio
archive. inject_firmware.sh only supported gzip-compressed cpio, so it
could not extract /init from this archive.
Add zstd-decompress to decompress zstd streams (uncompressed size is
about 180 KB).
Add unpack_initramfs.sh which is able to decompress uncompressed, gzip,
or zstd archives, with multiple segments, much like the Linux kernel
itself does.
Use unpack_initramfs.sh to extract /init for blob jail.
Don't compress the new archive segment containing firmware and the
updated /init.

These changes primarily improve server boards using BMC video. The
correct DRI card is selected even if it isn't the first one, and
performance is greatly improved on non-UMA cards.

This is particularly beneficial for servers with Aspeed BMC video,
because it introduces framebuffer console acceleration. The
framebuffer console is much more responsive.
Patches were ported from 5.10.5:
0001-fake-acpi.patch: This may not be needed any more, but it applies
cleanly and I don't think it would harm anything.
0002-nmi-squelch.patch: The comment mentions qemu but I see this
message on physical machines occasionally, so I think this is needed.
0003-fake-trampoline.patch: This patch does not apply cleanly. It
could be ported, but I don't think it's needed, I dropped it. Dates
back to a very old commit where Linux was being embedded into a vendor
UEFI firmware: a4d7654b1e.
0010-winterfell-ahci.patch: Minor change of %x to %lx in context.

PureBoot doesn't have any other three-valued settings and this doesn't
present very well in the config UI.
Instead make this a two-valued setting; drop the mode that forces the
EC setting to "stay off" at every boot because this is the default.
When disabling automatic power-on, disable the EC BRAM setting too.

Stop manually loading config values, just update config in environment.
Never test values against "n", since many default to empty. Always
test ="y" or !="y", any other value is off.
Add set_user_config() function to set a value in config.user,
combine configs, and update config in environment. Use it in setting
implementations.
Remove toggle_config, it wasn't very useful because the settings still
test y/n in order to show specific confirmation and success messages.

Blob jail provides device firmware blobs to the OS, so the OS does not
have to ship them. The firmware is passed through the initrd to
/run/firmware, so it works with both installed and live OSes, and there
are no race conditions between firmware load and firmware availability.
The injection method in the initrd is specific to the style of init
script used by PureOS, since it must add a copy command to copy the
firmware from the initrd to /run. If the init script is not of this
type, boot proceeds without device firmware.
This feature can be enabled or disabled from the config GUI.
Blob jail is enabled automatically if the Intel AX200 Wi-Fi module is
installed and the feature hasn't been explicitly configured.

USB autoboot automatically boots to a USB flash drive if one is present
during boot. This is intended for headless deployments as a method to
recover the installed operating system from USB without needing to
attach a display and keyboard.
USB autoboot can be controlled in config.user and the config GUI.

Restricted Boot mode only allows booting from signed files, whether that
is signed kernels in /boot or signed ISOs on mounted USB disks. This
disables booting from abitrary USB disks as well as the forced "unsafe"
boot mode. This also disables the recovery console so you can't bypass
this mode simply by running kexec manually.

PureBoot Basic mode provides the full Linux userspace in firmware from
Heads without requiring verified boot or a Librem Key. Basic and
verified boot can be switched freely without changing firmware, such as
if a Librem Key is lost.
PureBoot Basic can apply firmware updates from a USB flash drive, and
having a complete Linux userspace enables more sophisticated recovery
options.
Basic mode boots to the first boot option by default, setting a default
is not required. This can be configured in the config GUI.
