# Building the upstream kernel for Pixel 6 / 6 Pro

This README details how to build and flash an upstream kernel
to a Pixel 6 / 6 Pro phone.

## Get the kernel source

**Note**: If you are setting up your build environment for the first time,
follow the steps in the section [Install host dependencies](#install-host-dependencies).

```
repo init -u https://git.codelinaro.org/linaro/googlelt/manifest.git -b main
repo sync -j64 --jobs-checkout=$(nproc) -c --no-tags
```

## Compile and flash

To build and package the kernel images, run the command:

```
make images
```

To flash the kernel, [put your device in fastboot mode](#setup-the-phone-for-flashing)
and run the command:

```
make flash
```

This will prepare the device for development, flash and then boot the images:
```
out/images/boot.img
out/images/vendor_boot.img
```

By default, the device will boot to a minimal BusyBox-based console using
a prebuilt initramfs. To boot to a more complete initramfs that supports
autoloading kernel modules via udev, refer to the section
[Configuring the initramfs](#configuring-the-initramfs).

**Note:** Since upstream doesn't support devicetree overlays in the same way
Android does, we package the full devicetree blobs (dtbs) with the
`vendor_boot.img` and erase the `dtbo` partition.

For more advanced `make` operations, take a look at the additional `make`
targets by running `make help`.

### Rebooting the device with the upstream kernel

Currently, rebooting the device via the `reboot` command is not supported.
Instead of holding the power button for a minute, you can reboot the device by
run the following command from the serial console:

```
echo b > /proc/sysrq-trigger
```

Alternatively you can reboot via SysRq over the serial line by sending
\<BREAK\>-r. When using minicom, BREAK is sent via Meta-F.


### Configuring the initramfs

To boot to a console, an initramfs in required. The default `make` targets use
a prebuilt minimal BusyBox-based initramfs included in the repo clone.

To create a more complete initramfs using the [Yocto](https://www.yoctoproject.org/)
build environment, follow the steps below. This initramfs will include additional
command line tools and support automatic kernel module loading, amongst others.
We can subsequently point `make` at that initramfs instead.

1) Sync our OpenEmbedded repo manifest:

```
repo init -u https://git.codelinaro.org/linaro/googlelt/manifest.git -b oe/master -m default.xml
repo sync -j64 --jobs-checkout=$(nproc) -c --no-tags
```

2) Create the Yocto build directory using the `setup-environment` script. For
hermeticity purposes, this needs to be outside of /usr. Since in some
environments $HOME is below /usr, the example below initialises the build
directory to be below `/yocto-builds/yocto/`.

```
sudo mkdir -p /yocto-builds/yocto
sudo chown -R ${USER}:$(id -gn ${USER}) /yocto-builds
MACHINE=google-gs DISTRO=poky EXTRA_LAYERS="meta-openembedded/meta-oe" . ./setup-environment /yocto-builds/yocto/build-google-gs-poky
echo 'IMAGE_CLASSES:append:gs = " image-as-nokernel-initramfsrootfs"' >> conf/local.conf
```

**Note**: The `setup-environment` script needs to be sourced before invoking
bitbake each time a new shell is entered. On subsequent invocations of
`setup-environment`, i.e. once the build directory exists, the additional
arguments (`DISTRO`, `MACHINE`, etc.) do not need to be passed-in anymore.

3) Build the Yocto-based initramfs using the following commands:

```
umask 0022
bitbake core-image-full-cmdline
```

The initramfs can be found at the path:
```
/yocto-builds/yocto/build-google-gs-poky/tmp/deploy/images/google-gs/core-image-minimal-google-gs.cpio
```

To use the newly built Yocto initramfs, inject it into make using the
`PREBUILT_CPIO` make variable, e.g.:

```
make PREBUILT_CPIO=/yocto-builds/yocto/build-google-gs-poky/tmp/deploy/images/google-gs/core-image-full-cmdline-google-gs.cpio flash
```

Refer to the [Yocto documentation](https://docs.yoctoproject.org/), in
particular
[Customizing Images Using local.conf](https://docs.yoctoproject.org/dev-manual/customizing-images.html#customizing-images-using-local-conf),
for instuctions on how to add additional packages to that initramfs if desired.

## Setup your build environment and Pixel device

### Install host dependencies:

```
sudo apt-get install bison flex gcc-aarch64-linux-gnu libssl-dev lld lz4 pigz rsync
sudo apt install python3 python3-dev python3-venv swig
python3 -m venv venv
. venv/bin/activate
pip3 install dtschema rfc3987 yamllint
```

### Setup the phone for flashing

As the upstream kernel support is currently quite limited a [USB-Cereal](https://www.crowdsupply.com/0xda/usb-cereal)
device is required to obtain the serial console access and interact with
the kernel.

This should be connected to the phone and splits the debug UART from the
ADB/fastboot connection. Both ADB and UART should be connected to the host
computer.

**Note 1**: Select 1.8v voltage selection on USB-Cereal (small switch on left side)

**Note 2**: USB-Cereal has no orientation detection. If you don't have a working
serial console, change the orientation of the dongle or cable connecting to the
phone.

**Note 3**: The USB connectors on previous debug dongles have known to be quite
fragile with repeated plugging and unplugging. To avoid issues we usually use a
set of 3x usb-c cables so the dongle does not need to be repeadedly plugged amd
unplugged. This setup avoids unnecessary strain on the USB-Cereal connectors.

The image below shows an example cable setup, with the phone in fastboot mode.

![Pixel 6 Setup](imgs/p21cables.jpg)

### Entering fastboot

Now ensure the Pixel phone is connected via USB and is in fastboot mode
ready for flashing new images.

To enter fastboot mode, **press and hold the power and volume down keys
simultaneously** in the bootloader when the phone first turns on. Once
you've entered fastboot mode the phone will display a red triangle and
say "fastboot mode" in red writing amongst other information. Refer to
the image above.

It is always possible to reboot into fastboot mode (for example from
a crashed development kernel) **by doing a long (60seconds or so) power and
volume down key press**. This will then allow a new kernel to be flashed.


## Additional information

### Makefile tips

Since make inspects `GNUmakefile` before `Makefile`, I am using this to affect the
build without having a diff on the Makefile:

```
$ > cat GNUmakefile
# fastboot via network
export ANDROID_SERIAL := tcp:localhost:35799
export PATH := ${HOME}/devel/google/android-master/out/host/linux-x86/bin:${PATH}

# yocto initramfs
PREBUILT_CPIO := /yocto-builds/yocto/build-google-gs-poky/tmp/deploy/images/google-gs/core-image-full-cmdline-google-gs.cpio

include ./Makefile
```
and I still can just type `make run`.

### Bootloader notes

Some versions of the Pixel 6 bootloader crash when no DTBO exists in
flash. A version that is known to work is: slider-1.3-11000330:

```
$ fastboot flash bootloader bootloader.img
$ fastboot reboot-bootloader

$ fastboot getvar version-bootloader
version-bootloader: slider-1.3-11000330
```

Other bootloader versions that are known to not crash are:
* slider-1.2-8739948
* slider-1.2-9152140

If you don't have access to a known-good bootloader, you can re-enable
flashing of the DTBO by updating Makefile accordingly (configure_fastboot:
and flash: targets).
