Latest

4.19.152 and 5.4.72

Note

I may test only v5.4-general-surface build on Surface 3. If something is not working on your Surface devices, feel free to open issues.
I stopped releasing -minimal-surface kernel from this release.

general-surface: using config-general-surface. Use this one If you want a more general kernel (closer to normal Linux distros, with support of Surface devices). Probably work also on non-surface devices.
minimal-surface: using config-minimal-surface. Use this one if you want a minimal kernel (closer to chromiumos' original kernels, with support of Surface devices). Chances are low to work on non-surface devices.
k5: abbreviation of kitakar5525. Means additional patches are applied.

Difference between v4.19 and v5.4

All the features that work/not-work with linux+linux-surface kernel should work/not-work also with this release.
It's reported that v4.19 kernels don't boot on SP7/SL3. Use v5.4 kernels.

IPTS Touchscreen on v5.4

If your device uses IPTS, you need to install iptsd (see https://github.com/kitakar5525/chromeos-kernel-linux-surface/tree/master/patch-to-os-image).
What devices use IPTS and what devices don't?
There is chromeos-specific issue on iptsd. Finger tapping isn't working on chrome browser. Working on ARC, though.

major issues

chromeos-5.4: tpm_tis causes kernel oops #20: I recommend adding module_blacklist=tpm_tis to bootloader.
wifi/bt unstable when using with iwl7000 #17: For now, using CONFIG_IWLWIFI instead of chromiumos' default CONFIG_IWL7000.
iptsd is not fully working (not responding to touches on browser, but seems to be fully working on ARC).

Installation

Please read the whole instructions before you try to install until you
understand what the following commands do. I won't provide install scripts
(i.e. I won't provide a way to automate installation) because it's good
that everyone understands how things are done. If something is unclear
in the instructions, feel free to ask me(@kitakar5525) via opening a issue.

for brunch

Run the following commands under brunch chromeos.
(Can be run under dual-booted linux but then, make sure that there is
only one partition labeled ROOT-C (lsblk).)

Extract ROOT-C archive onto ROOT-C:

ROOT_C_MOUNT_DIR="/tmp/mnt/ROOT-C"

# 1. mount ROOT-C
sudo mkdir $ROOT_C_MOUNT_DIR
sudo mount /dev/disk/by-label/ROOT-C $ROOT_C_MOUNT_DIR

# 2. remove existing kitakar5525 kernel first
rm -rf $ROOT_C_MOUNT_DIR/packages/kitakar5525-kernel/*

# 3. (extra step)
# Requires ROOT-C free space about 100MB. Current brunch release has
# that extra space but in future releases, you might need to create
# free space by removing existing brunch kernel files...
# rm -rf $ROOT_C_MOUNT_DIR/lib/kernel-devel
# rm -rf $ROOT_C_MOUNT_DIR/lib/iwlwifi_backport
# rm -rf $ROOT_C_MOUNT_DIR/lib/modules

# 4. extract archive onto ROOT-C
sudo tar -xf "${_archive_name_you_want_to_use_}-ROOT-C.tar.gz" -C $ROOT_C_MOUNT_DIR

# 5. cleanup
## unmount ROOT-C
sudo umount $ROOT_C_MOUNT_DIR

for chromiumos

Extract archive into somewhere. In that archive, there is an archive
for ROOT-A (packages/kitakar5525-kernel/${_archive_name_you_want_to_use_}.tar.gz).

Usually, you can't mount ROOT-A manually. So, do the following under
chromiumos (not from dual-booted linux).
Be careful that running the following commands outside of chromiumos
breaks the system.

Extract the ROOT-A archive onto ROOT-A and copy vmlinuz into
EFI-SYSTEM/syslinux/vmlinuz.A:

ROOT_C_ARCHIVE_EXTRACT_DIR="/tmp/ROOT-C_archive"
EFI_SYSTEM_MOUNT_DIR="/tmp/mnt/EFI-SYSTEM"

# 1. extract ROOT-C archive into somewhere
mkdir $ROOT_C_ARCHIVE_EXTRACT_DIR
sudo tar -xf "${_archive_name_you_want_to_use_}.tar.gz" -C $ROOT_C_ARCHIVE_EXTRACT_DIR

# 2. mount EFI-SYSTEM
mkdir $EFI_SYSTEM_MOUNT_DIR
sudo mount /dev/disk/by-label/EFI-SYSTEM $EFI_SYSTEM_MOUNT_DIR
# 3. remount root directory as rw
sudo mount / -o rw,remount

# 4. remove existing kernel files
sudo rm -rf /boot/*
sudo rm -rf /lib/modules/*

# 5. extract ROOT-A archive onto ROOT-A
sudo tar -xf "$ROOT_C_ARCHIVE_EXTRACT_DIR/packages/kitakar5525-kernel/${_archive_name_you_want_to_use_}-ROOT-A.tar.gz" -C /
# 6. copy vmlinuz into EFI-SYSTEM
cp $ROOT_C_ARCHIVE_EXTRACT_DIR/kernel $EFI_SYSTEM_MOUNT_DIR/syslinux/vmlinuz.A

# 7. cleanup
## remount root directory as ro
sudo mount / -o ro,remount
## unmount EFI-SYSTEM
sudo umount $EFI_SYSTEM_MOUNT_DIR

enrolling secureboot public key (for the first time)

You need to enroll my secureboot public key for the first time you use
this kernel.
Take a look here:

https://github.com/kitakar5525/chromeos-kernel-linux-surface/tree/master/secureboot-public-key.

iptsd for v5.4

If your device uses IPTS, don't forget to install iptsd. (see https://github.com/kitakar5525/chromeos-kernel-linux-surface/tree/master/patch-to-os-image).

Installation

for brunch

Run the following commands under brunch chromeos.
(Can be run under dual-booted linux but then, make sure that there is
only one partition labeled ROOT-C (lsblk).)

Extract ROOT-C archive onto ROOT-C:

ROOT_C_MOUNT_DIR="/tmp/mnt/ROOT-C"

# 1. mount ROOT-C
sudo mkdir $ROOT_C_MOUNT_DIR
sudo mount /dev/disk/by-label/ROOT-C $ROOT_C_MOUNT_DIR

# 2. remove existing kitakar5525 kernel first
rm -rf $ROOT_C_MOUNT_DIR/packages/kitakar5525-kernel/*

# 3. (extra step)
# Requires ROOT-C free space about 100MB. Current brunch release has
# that extra space but in future releases, you might need to create
# free space by removing existing brunch kernel files...
# rm -rf $ROOT_C_MOUNT_DIR/lib/headers
# rm -rf $ROOT_C_MOUNT_DIR/lib/iwlwifi_backport
# rm -rf $ROOT_C_MOUNT_DIR/lib/modules

# 4. extract archive onto ROOT-C
sudo tar -xf "${_archive_name_you_want_to_use_}-ROOT-C.tar.gz" -C $ROOT_C_MOUNT_DIR

# 5. cleanup
## unmount ROOT-C
sudo umount $ROOT_C_MOUNT_DIR

for chromiumos

Extract archive into somewhere. In that archive, there is an archive
for ROOT-A (packages/kitakar5525-kernel/${_archive_name_you_want_to_use_}.tar.gz).

Usually, you can't mount ROOT-A manually. So, do the following under
chromiumos (not from dual-booted linux).
Be careful that running the following commands outside of chromiumos
breaks the system.

Extract the ROOT-A archive onto ROOT-A and copy vmlinuz into
EFI-SYSTEM/syslinux/vmlinuz.A:

ROOT_C_ARCHIVE_EXTRACT_DIR="/tmp/ROOT-C_archive"
EFI_SYSTEM_MOUNT_DIR="/tmp/mnt/EFI-SYSTEM"

# 1. extract ROOT-C archive into somewhere
mkdir $ROOT_C_ARCHIVE_EXTRACT_DIR
sudo tar -xf "${_archive_name_you_want_to_use_}.tar.gz" -C $ROOT_C_ARCHIVE_EXTRACT_DIR

# 2. mount EFI-SYSTEM
mkdir $EFI_SYSTEM_MOUNT_DIR
sudo mount /dev/disk/by-label/EFI-SYSTEM $EFI_SYSTEM_MOUNT_DIR
# 3. remount root directory as rw
sudo mount / -o rw,remount

# 4. remove existing kernel files
sudo rm -rf /boot/*
sudo rm -rf /lib/modules/*

# 5. extract ROOT-A archive onto ROOT-A
sudo tar -xf "$ROOT_C_ARCHIVE_EXTRACT_DIR/packages/kitakar5525-kernel/${_archive_name_you_want_to_use_}-ROOT-A.tar.gz" -C /
# 6. copy vmlinuz into EFI-SYSTEM
cp $ROOT_C_ARCHIVE_EXTRACT_DIR/kernel $EFI_SYSTEM_MOUNT_DIR/syslinux/vmlinuz.A

# 7. cleanup
## remount root directory as ro
sudo mount / -o ro,remount
## unmount EFI-SYSTEM
sudo umount $EFI_SYSTEM_MOUNT_DIR

enrolling secureboot public key (for the first time)

You need to enroll my secureboot public key for the first time you use
this kernel.

4.19.126 and 5.4.44

Note

general-surface: using config-general-surface. Use this one If you want a more general kernel (closer to normal Linux distros, with support of Surface devices). Probably work also on non-surface devices.
minimal-surface: using config-minimal-surface. Use this one if you want a minimal kernel (closer to chromiumos' original kernels, with support of Surface devices). Chances are low to work on non-surface devices.
k5: abbreviation of kitakar5525

Difference between v4.19 and v5.4

All the features that work/not-work with linux+linux-surface kernel should work/not-work also with this release. So, if you have devices that use IPTS, you may want to use v4.19 one for finger multitouch. What devices use IPTS and what devices don't?
It's reported that v4.19 kernels don't boot on SP7/SL3. Use v5.4 kernels.

Info: 4.19.126-09205-g5e9fefe31794

kernel tree used: https://github.com/kitakar5525/linux-surface-kernel/tree/chromeos-v4.19.126.r9174.95cd8329bd185+surface+k5-2

issues

chromeos-5.4: tpm_tis causes kernel oops #20. I recommend adding module_blacklist=tpm_tis to bootloader.
wifi/bt unstable when using with iwl7000 #17: For now, using CONFIG_IWLWIFI instead of chromiumos' default CONFIG_IWL7000.

chromeos-v5.4.39.r4076.d37238f2773c3-surface-brunch Pre-release

Pre-release

Always backup local files before updating kernel; it may refresh your local data.

Issues:

Not bootable on SB1 !!!. It reboots on chrome logo. (But works well on Surface 3... why?)
~~I released this binary anyway because it works with Surface 3. I'll look into what's happening on SB1 later.~~
~~So, if you want to use v5.4 kernels but this release doesn't work, try 5.4.24 version for now.~~
EDIT: after installing other kernel version then reinstalling this version, it started working on SB1. Hmm?
Surface 3: config-general-surface: ACPI error messages appear continuously on dmesg #15
Because of this issue, mark this release as pre-release.

Note: I switched kernel config from config-minimal-surface to config-general-surface from this release.

Installation

Chromium OS:

Extract the release binary
Extract the compressed lib dir (lib.tar.gz)
Copy the lib dir under ROOT-A/
Copy the boot/vmlinuz* to EFI-SYSTEM/syslinux/vmlinuz.A

Brunch:

Extract the release binary
Extract the compressed lib dir (lib.tar.gz)
Copy the lib dir under ROOT-C/
Copy the boot/vmlinuz* to ROOT-C/kernel

Note: kernel is not signed with secure boot key. Please do it manually yourself for now.

Note 2: for Chromium OS, you need to install mwifiex firmware.

Note 3: for Brunch, you need to resize ROOT-C to larger size (e.g. 2GB) until #3 is fixed because size of this kernel is too large without compression due to general kernel config (config-general-surface).

Note

Kernel tree info:

patch version: v4.0.1 (https://github.com/kitakar5525/linux-surface-patches/releases/tag/v4.0.1)
(Means that the kernel tree is derived from chromeos-v5.4.39.r4076.d37238f2773c3 and contains the v4.0.1 patches)
chromeos-v5.4.39.r4076.d37238f2773c3 means that the kernel tree is derived from chromeos-5.4 commit d37238f2773c3

This build contains patches from linux-surface and brunch.
Especially, including the following patches that is necessary for brunch framework:

The product_name will be "Brunch".

$ cat /sys/devices/virtual/dmi/id/product_name
Brunch

IPTS supports Stylus and Singletouch finger input and not support Multitouch finger input yet. Default is in Multitouch mode. You can toggle the mode like this: sudo modprobe -r ipts; sudo modprobe ipts singletouch=Y. If you need Multitouch finger input support, use 4.19 kernels for now.

chromeos-kernel-linux-surface-5.4.24

Always backup local files before updating kernel! Especially, be careful when switching kernel series (like 4.19 to 5.4); it may refresh your local data.

Currently, IPTS on 5.4 series don't support finger multitouch input. Take a look at 4.19 series for that support.
What devices use IPTS and what devices don't?: https://github.com/linux-surface/linux-surface/wiki/Installation-and-Setup#what-devices-use-ipts-and-what-devices-dont

Installation

NOTE:

IPTS supports Stylus and Singletouch finger input and not support Multitouch finger input yet. Default is in Multitouch mode. You can toggle the mode like this: sudo modprobe -r ipts; sudo modprobe ipts singletouch=1. If you need Multitouch finger input support, use 4.19 kernels for now.
