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. Signed-off-by: Leah Rowe <leah@libreboot.org>
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: don't boot linux without a grub.cfgLeah Rowe
the fallback code in the main menuentry is potentially unsafe, depending on user config. 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>

grub.cfg: add BTRFS subvol support
2023-11-13grub: re-add fat/nt file system modulesLeah Rowe
apparently some people use fat file systems for /boot on linux systems this is apparently a thing it's ridiculous, but also a thing a user reported they could not boot their t400 because of those, because they have such a distro installed on their machine apparently it was a gentoo user i don't really care. re-add 1980s dos file system support.

2023-11-05grub: avoid printing empty error messagesLeah Rowe
this replaces the previous behaviour, which erred on a specific value of grub_errno, which was a problem if other types of errors used that value. due to the way i patch out the prefix error messages, this new patch ensures that only those errors are silenced. all other messages will be printed. Signed-off-by: Leah Rowe <leah@libreboot.org>
2023-11-05further silence grub prefix errorsLeah Rowe
it still printed "error: ." on screen, instead of the prefix message. now it's silent. it just says: Welcome to GRUB! Signed-off-by: Leah Rowe <leah@libreboot.org>
2023-11-05grub: don't print messages if a module isn't foundLeah Rowe
it can annoy some users, so just silence it. we don't need a lot of modules so we only have a few, but some distro grub configs can load modules frivilously. Signed-off-by: Leah Rowe <leah@libreboot.org>
2023-11-05grub: don't print prefix errors on the screenLeah Rowe
still set grub_errno, and behave the same, but don't print anything. just carry on execution as normal. Signed-off-by: Leah Rowe <leah@libreboot.org>

2023-10-31GRUB: don't spew "Unknown key 0xff" in errorLeah Rowe
Faulty keyboards make GRUB unusable. Normally it happens when a user plugs in a faulty USB keyboard, but if it's the laptop keyboard, then GRUB becomes unusable and the user cannot boot anything. So, your laptop keyboard is a ticking timebomb if you use GRUB; with this patch, that's no longer the case. Signed-off-by: Leah Rowe <leah@libreboot.org>
2023-10-31fix grub keyboard init on dell e6400 and e6430Leah Rowe
also, enable seabios_withgrub on e6400, but not grubfirst; right now, we also support dgpu which would brick on grubfirst. on my tested nvidia model, loading grub from seabios worked, so i'm going to re-add seabios_grubfirst functionality like in older libreboot revisions, enabled selectively on a given target. e6430 currently only has igpu support anyway, but i've done the same thing there, in anticipation of future dgpu support. e6400 and e6430 ec report scancode set 2 with translation by default, but only actually output scancode set 1 grub is trying to use scancode set 2 without scancode translation, so the key inputs get messed up fix it by forcing scancode set 2 with translation, but only on coreboot; other build targets on GRUB will retain the same behaviour as before courtesy goes to Nicholas Chin who inspired me, and helped me to fix this. tested on Nicholas's E6400 and E6430, and my E6400; Riku also tested it on non-Dell, as did I (some thinkpads), and all seems OK. The new behaviour in coreboot GRUB is essentially no different to that of SeaBIOS, which does the same. 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>
