notes on script design🔗

nfs attach script🔗

# notes - follow freebsd-m1 setup page
echo "mount -v -t nfs 192.168.64.1:/System/Volumes/Data/Users/smk/personal/gsoc/fbsd/tools/boot/bootloader_test /root/freebsd-src/tools/boot/bootloader_test" >> mount.sh
chmod +x mount.sh
# later configure to execute on bootup
  • There is an issue when mounting entire freebsd-src from Mac. Seems like its attaching in a read-only mode which interferes with buildworld, buildkernel steps
  • There is another issue while running amd64 builds from arm64 qemu running requires to build toolchain
# building toolchain
cd freebsd-src
# assumes buildworld and buildkernel is done
make -j `sysctl -n hw.ncpu` TARGET=amd64 TARGET_ARCH=amd64 toolchain
# optionally could use : toolchains to build everything

notes on amd64🔗

  • really already been solved by warner

notes on arm64🔗

  • Check nfs attach script section’s 2nd portion

notes on riscv🔗

default boot mode for my script is using opensbi

# install opensbi & optionally u-boot
pkg install opensbi u-boot-qemu-riscv64

notes on armv7🔗

This image is always released as IMG file, which could be tricky to handle in bootloader_tests script which is a lua script.

  • Decided to convert .img into .iso

How do we get all the files ?

# uncompress the xz
xz -k FreeBSD-13.2-RELEASE-arm-armv7-GENERICSD.img.xz

# then create a virtual device with this uncompressed image
mdconfig -a -t vnode -f FreeBSD-13.2-RELEASE-arm-armv7-GENERICSD.img -u 0
# this should mount the virtual device as md0 & confirm it as
mdconfig -l
ls /dev/md0*        # output should be md0, md0s1, md0s2, md0s2a

# lets find out file-system of each of them
file FreeBSD-13.2-RELEASE-arm-armv7-GENERICSD.img
fstyp /dev/md0s2a           # this should be required ufs partition

# mounting
mount -t ufs /dev/md0s2a /mnt/armv7

# cleanup: unmount & delete virtual device
unmount /mnt/armv7
mdconfig -d -u 0

Creating ISO

# install cdutils
pkg install sysutils/cdrtools

# in qemu cd-writer needs to configured so rather let's write the folder into iso
# method-1 directly make iso from /mnt/armv7
mkisofs -o FreeBSD-13.2-RELEASE-arm-armv7-bootonly.iso /mnt/armv7

# method-2 cause big image :(
cp -r /mnt/armv7 ~/data_src/armv7
mkisofs -o FreeBSD-13.2-RELEASE-arm-armv7-bootonly.iso ~/data_src/armv7

# if not in qemu
cdrecord dev=md0 imagefile.iso

# reference : https://docs.freebsd.org/en/books/handbook/disks/#creating-cds

# armv7 requires
pkg install sysutils/u-boot-qemu-arm
