2024-01-18GRUB: insert only 1 keymap per board, in cbfsLeah Rowe
There is no need to add multiple keymap files, because GRUB can load keymaps from CBFS. The current build logic is designed to avoid building multiple GRUB binaries, which are expensive computationally because each one would then have to be compressed for each board. This patch provides the best of both worlds: less space used in flash like in the old lbmk design (1 keymap per board), but retaining the current build speeds and therefore not re-introducing the slowness of lbmk's previous GRUB build logic. The grub.cfg file has been modified, accordingly. It now only loads a keymap.gkb file from CBFS, by default. It does this, only if that file exists; if not, GRUB already defaults to US Qwerty layout anyway. ALSO: compress all keymap gkb files with xz -6 GRUB automatically decompresses files when accessed. This results in about 2KB of flash space saved in CBFS. Here is real-world data, showing the increased flash space: < fallback/payload 0x3eb80 simple elf 548821 none < keymap.cfg 0xc4bc0 raw 16 none < (empty) 0xc4c00 null 11633316 none --- > fallback/payload 0x3eb80 simple elf 546787 none > keymap.gkb 0xc43c0 raw 344 none > (empty) 0xc4540 null 11635044 none This was taken by diffing the cbfstool "print" output, both before and after. The *after* result is with this change. 11633316. In this example, 1728 bytes have been saved. Therefore, with compression taken into account, this patch saves about 1.7KB of space in CBFS. This change means that lbmk can now scale to support hundreds of keymaps, without increasing the amount of flash space used, in each given image. Since the keymap files are compressed in lbmk.git, in advance, we spend no additional time on compression at build time. The resulting change in build speed in negligible. Adding your own keymap.gkb file was already possible, for changing the keymap in libreboot images, if you didn't want to change the memdisk (and thus re-compile grub.elf). Now, this is the default behaviour, and the only way to do it. It's much more efficient. The original keymap files can be restored, by running unxz. Signed-off-by: Leah Rowe <leah@libreboot.org>

2023-12-18grub.cfg: support grub and extlinux on ata/ahciLeah Rowe
there are special menuentries just for loading configs, without handling luks, lvm and whatnot. it's intended for users of cd/dvd drives. well, now we support both extlinux and grub, with this patch. Signed-off-by: Leah Rowe <leah@libreboot.org>
2023-12-18grub.cfg: merge isolinux/grub usb menuentriesLeah Rowe
many modern distros use grub in their installer images, so scan for grub.cfg first. Signed-off-by: Leah Rowe <leah@libreboot.org>
2023-12-18grub.cfg: handle extlinux in the default menuentryLeah Rowe
isolinux/syslinux/extlinux config files should all work, using the syslinux parser function in grub the current behaviour is to only search for grub.cfg, so extlinux users can't use the default libreboot setup. with this change, their systems should hopefully work.

2023-12-18grub.cfg syslinux: support ESP and extlinux.confLeah Rowe
the so-called EFI System Partition (ESP) is used on many UEFI-based setups. some users may be migrating to libreboot, so let's support it. on BIOS setups, it would be e.g. /boot/syslinux/syslinux.conf on UEFI setups, it would be e.g. /boot/EFI/syslinux/syslinux.conf additionally, support scanning for extlinux.conf Signed-off-by: Leah Rowe <leah@libreboot.org>

2023-12-18grub.cfg: scan lvm volumes lastLeah Rowe
lvm/* is slow to resolve in grub, on some machines, because grub enumeration is very slow in general. however, many people will install distros with any number of lvm configurations, so we should try to support them. Signed-off-by: Leah Rowe <leah@libreboot.org>
2023-12-18Revert "grub.cfg: try luks2/crypto-lvm before non-crypto"Leah Rowe
This reverts commit 20389655e42e62ebf6d96dd106c91fbe74282557. If the user actually has encryption, but has /boot unencrypted, this will considerably slow down the boot, so the patch has been reverted. The patch was originally meant to favour encrypted /boot setups, but the old behaviour also still works there.
2023-12-18grub.cfg: try luks2/crypto-lvm before non-cryptoLeah Rowe
when the user sets up an encrypted machine, grub.cfg defaults to non-encrypted setups if found, first this patch reverses the order, deferring to non-encrypted installations only when encrypted ones are unavailable Signed-off-by: Leah Rowe <leah@libreboot.org>

2023-10-21change default volname in grub.cfgLeah Rowe
it's been a while since we did encrypted /boot and the current name sucks. it's unlikely that anyone still uses it, but people will soon change the default assumed lvm name to grubcrypt and stick to that. Signed-off-by: Leah Rowe <leah@libreboot.org>
2023-10-02grub.cfg: disable the pagerLeah Rowe
The pager causes trouble in some cases, where the user has to press enter at boot time depending on the configuration. Interactive use is one thing, but we should leave this disabled for smoother experience. If the user *wishes* to use the shell, they can always just enable the pager themselves by doing: set pager=1 Signed-off-by: Leah Rowe <leah@libreboot.org>

2023-09-09set grub.cfg timeout to 5s (10 on some boards)Leah Rowe
target.cfg can now specify e.g. grub_timeout=20 this would then be inserted as timeout.cfg in cbfs, containing the instruction: set timeout=20 HP laptops need a bit of extra time, due to the delay caused by the EC bug workaround deployed in GRUB desktops in general need extra time. this too is set to 10s, like the HP laptops. only insert timeout.cfg if actually needed (declared in target.cfg), otherwise grub.cfg will default to 5s Signed-off-by: Leah Rowe <leah@libreboot.org>
