kboot: Move to kboot/kbootIn anticipation of separating the library elements from the kbootprorgam elements, move kboot down a level into a subdirectory. Therewill be libkboot and include directories in subsequent commits,mirroring other subsystems like i386 and efi.Sponsored by: Netflix List of files: /freebsd/stand/kboot/Makefile

Thu, 11 Feb 2021 15:29:00 +0100

loader: always install help filesAddress two issues with current help file logic:The existing condition prevents the common help file from beinginstalled when there are no additional help files defined. This resultsin no loader.help on EFI platforms, for example.Second, due to the fact that we build and install multiple loader types,each successive install will clobber the previous loader.help. Theresult is that we could lose type-specific commands, or possibly listthem in loaders that do not have such commands.Instead, give each loader type a uniquely named help file. The EFIloader will look for /boot/loader.help.efi, userboot will look for/boot/loader.help.userboot, etc. The interpreter variant has no effecton which help file is loaded.This leaves the old /boot/loader.help unused.Some credit for the final approach goes to Mathieu for their version of the fix in https://reviews.freebsd.org/D22951.PR: 267134Reported by: Daniel O'Connor Reviewed by: impMFC after: 1 weekDifferential Revision: https://reviews.freebsd.org/D28591 List of files: /freebsd/stand/kboot/Makefile

stand: share bootinfo.c between EFI and KBOOTConnect efi's bootinfo.c to the kboot build, and adjust to usethe kboot specific routines.The getrootmount() call is independent of EFI. Remove ifdefs so it'scalled for kboot too.The differences between the kboot and efi bootinfo.c files are now tiny.This could use some more refactoring, but this is a working checkpoint.Sponsored by: NetflixReviewed by: tsoomeDifferential Revision: https://reviews.freebsd.org/D38350 List of files: /freebsd/stand/kboot/Makefile

kboot: Add hostfsAdd hostfs for the Linux environment. We can't use the userboot onethat's kinda similar because the Linux system calls we have in kboot arenot quite POSIX compliant (Linux takes care of providing the POSIXinterface in libc), so we have to cope with a number of quirks in thatarea.Sponsored by: NetflixDifferential Revision: https://reviews.freebsd.org/D36607 List of files: /freebsd/stand/kboot/Makefile

cc7b630cec8320ad979af6b29cb67027f6a95456 - stand/kboot: Add note about why we use MACHINE_ARCH here

Sun, 04 Sep 2022 17:31:51 +0200

stand/kboot: Add note about why we use MACHINE_ARCH hereNormally in the boot loader, we key off of MACHINE since that specifiesthe kernel and the loader is very tuned to each type of MACHINE ingeneral. In this case, however, we're producing a Linux binary, withLinux system calls encoded in it. These align better along theMACHINE_ARCH axis of FreeBSD. For PowerPC the system calls are radicallydifferent for each of our MACHINE_ARCHes, with only powerpc64 andpowerpc64le sharing the same numbers and memory layout. The same wastrue about mips when it was in the tree. 32-bit arm uses the samelayout, however, for both armv6 and armv7 ports: that can be easilyshared in the unlikely event we support that in the future.Sponsored by: Netflix List of files: /freebsd/stand/kboot/Makefile

Thu, 01 Sep 2022 19:06:43 +0200

kboot: add minmalist init functionalityIt is desirable to run kboot as the first program in some LinuxBootenvironments. This is the traditional "pid 1" or "init" program. Whenrunning as pid 1. rovide a minimal environment based on what sysvinit,u-root, initramfs-tools and other like projects do. We mount /dev, /sys,/proc, make symlinks from /dev/fd to /dev/proc, and create /tmp, /run,and /var. We also setup stdin/out/err to the console, set the ttycharacteristics of same and block the appropriate signals.This is indended as an environment that never does a fork/exec. Ifthat's required, the process groups, session leaders and all thingsPOSIX terminal handlers will need to be added.Unlike the general purpose linux projects in this area, no attempt ismade to support very old kernels.When not pid 1, we skip all of the above.Sponsored by: NetflixDifferential Revision: https://reviews.freebsd.org/D36368 List of files: /freebsd/stand/kboot/Makefile
