UTM MacOS Silicon: How to compile Linux Kernel on a Debian Guest

Debian Packages​

Download Latest STABLE Kernel​

# START =============================================================
STABLE=$(wget -O - -o /dev/null https://www.kernel.org/finger_banner | awk '/stable/ {print $NF; exit}')   
MAJOR=$(echo $STABLE | cut -d. -f1)
URL="https://kernel.org/pub/linux/kernel/v$MAJOR.x"
KERNEL="linux-$STABLE.tar.xz"
TARBALL="linux-$STABLE.tar"
PGP="linux-$STABLE.tar.sign"
KURL="$URL/$KERNEL"
PURL="$URL/$PGP"

# ===================================================================
# Wget the latest kernel stable version
wget -c $KURL
# ===================================================================
# Wget the signature
wget -c $PURL
# ===================================================================
# Locate Keys
gpg --locate-keys torvalds@kernel.org gregkh@kernel.org

Sign Key (optional)​

gpg --sign-key gregkh@kernel.org

Uncompress the file and verify​

# ===================================================================
# Uncompress
unxz $KERNEL
# Verify
gpg --verify $PGP $TARBALL

Extract TAR file​

# ===================================================================
tar xf $TARBALL
# ===================================================================
cd linux-$STABLE

Overkilled Cleaning Habit​

Once in a while, some Bozo will ask about why not "make distclean," or "make mrproper," or "make clean." Ok, this is the way! 

make distclean; make mrproper; make clean;

ARM64 Option 1: Reusing ".config" files​

caution
  • Run:
yes "" | make oldconfig

ARM64 OPTION 2: A ".config" file from scratch​

  • If OPTION 1 failed, consider making a .config file from scratch with:
cp arch/arm64/configs/defconfig .
yes "" | make oldconfig
make menuconfig

E.g., for cbkadal​

General setup  --->
  (-cbkadal-10) Local version - append to kernel release
  Kernel compression mode (XZ)  --->
  (cbkadal) Default hostname
  <*> Kernel .config support
  [*] Enable access to .config through /proc/config.gz
  <*> Enable kernel headers through /sys/kernel/kheaders.tar.xz
Processor type and features  --->
  [ ] EFI runtime service support
Device Drivers --->
  Firmware Drivers --->
    [*] Disable EFI runtime services support by default
File systems  --->
  <*> FUSE (Filesystem in Userspace) support
  <*>   Character device in Userspace support
  <*>   Virtio Filesystem
Kernel hacking  --->
  Compile-time checks and compiler options  --->
    [*] Install uapi headers to usr/include

Compile (make)​

time make
  • FYI Compile Time:
    • (Linux) Intel(R) Core(TM) i5-9400F CPU @ 2.90GHz
      • real 3m5.825s
      • user 14m51.339s
      • sys 1m59.721s

Install​

  • User: root
    • Use sudo if you wish.
    • Change Directory (cd) to the linux kernel source!
# USER: ROOT ============
make modules_install

make install

make headers_install INSTALL_HDR_PATH=/usr

Known Boot Errors​

ata1.00: Read log 0x00 page 0x00 failed, Emask 0x1

Linux Firmware​

cp -r i915/ /lib/firmware/
cp -r tigon/ /lib/firmware/
cp -r e100/ /lib/firmware/
cp -r rtl_nic/ /lib/firmware/

Old Modules​

  • You have to delete old modules /lib/modules and old config /boot/ files manually. Do not forget to update-grub.
  • Visit (ROOT):
cd /lib/modules/
ls -al
cd /boot/
ls -a
