* stand: Cut over to using the EDK2 filesWarner Losh2025-11-162-1/+4
| | | | | | | | | | | | | | | | | | | | | | Remove the old EFI SDK files that we've been nursing along for too many years. Replace them with files from EDK2 edk2-stable202502 and tweak the interfaces we need to tweak. Mostly include different things or change the names of the protocols that no longer have old-school compat names. I gave up in the middle of env.c, too damn tedious to find all those new GUIDs. Also, many of the guids were mystery meat, most likely from the EDK2 sources, but just not the Include subdirectory. Need to investigate those. And the memory info? Is it just an oboslete thing, or embedded knowledge of EDK2. Delete the now-redundant copies of things in Guid and Protocol. I debated keeping ZeroGuid.h, but EDK2 has moved on from when I snagged it years ago (or maybe I just invented it out of whole cloth: edk2 does radically different things today and I didn't do the git deep-dive to find out).

Where style(9) was followed this is easy, where it was ignored, aim for the first block of sys/*.h headers and don't get too fussy or try to fix other style bugs.

* boot: Always use ELF Tool Chain elfcopy for EFI buildsEd Maste2025-03-231-1/+1
| | | | | | | | | | | | | | | | We now use llvm-objcopy by default (as of commit 1cae7121c667), but it does not support efi-app-x86_64 and similar ouptut formats (for more detail see LLVM issue 108609[1]).

* boot1.efi: Don't redundantly include devpath.cWarner Losh2024-05-071-2/+1
| | | | | | | | | | | | | devpath.c is on both the comand line and in libefi. This is redundant and was a mistake in 4cf36aa1017f9. It never should have been here. In practice, this just means that the devpath.o from libefi.a goes unused. This will cause problems with some upcoming changes (D44872) to enable LTO to reduce the size of the binaries, so go ahead and make the change now to reduce the changeset for that.

* stand/boot1.efi: Implement bootonce for ZFSWarner Losh2023-05-011-1/+26
| | | | | | | | | | | | | | Implement ZFS bootonce protocol. We pass zfs-bootonce=t to the next boot stage as a command line argument. Unlike zfsboot -> loader handoff in the BIOS case, we don't use the OS_BOOTONCE_USED. This would require modifications to loader.efi which would only server to make it more complicated. Instead, use the command line parsing interface for the boot1.efi -> loader.efi to pass in the zfs-bootonce kenv that will be needed by rc.d/zfsbe to activate the BE if boot progresses that far.

* loader: zfs should support bootonce an nextbootToomas Soome2020-09-212-2/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | bootonce feature is temporary, one time boot, activated by "bectl activate -t BE", "bectl activate -T BE" will reset the bootonce flag. By default, the bootonce setting is reset on attempt to boot and the next boot will use previously active BE. By setting zfs_bootonce_activate="YES" in rc.conf, the bootonce BE will be set permanently active. bootonce dataset name is recorded in boot pool labels, bootenv area. in case of nextboot, the nextboot_enable boolean variable is recorded in freebsd:nvstore nvlist, also stored in boot pool label bootenv area. On boot, the loader will process /boot/nextboot.conf if nextboot_enable is "YES", and will set nextboot_enable to "NO", preventing /boot/nextboot.conf processing on next boot. bootonce and nextboot features are usable in both UEFI and BIOS boot. To use bootonce/nextboot features, the boot loader needs to be updated on disk; if loader.efi is stored on ESP, then ESP needs to be updated and for BIOS boot, stage2 (zfsboot or gptzfsboot) needs to be updated (gpart or other tools). At this time, only lua loader is updated. Sponsored by: Netflix, Klara Inc. Differential Revision: https://reviews.freebsd.org/D25512 Notes: svn path=/head/; revision=365938

| | | | | | | | | | | | | | | The zfs reader development did reach to the point where linking boot1, we will get errors about duplicate symbols Malloc, Free, Calloc. We can just use libsa version, just as loader.efi does. The only concern is, libsa zalloc is using fixed size heap region, I did pick 64MB as other stage instances are using, but this size is likely not optimal.
