Lately, I’ve been trying to port my android tablet to Postmarket OS, well PostmarketOS (from here on I will refer it as pmos) is a Linux distribution intended for mobile phones. Well pmos lets a user run mainstream linux kernel along with the utilities used by common Linux distributions ranging from init system like systemd to complete desktop environments. Though these utilities are tweaked heavily to suit mobile phone layouts, like Phosh (maintained by pmos community) basically works like gnome for phones, there exists others like plasma-mobile and many window managers. This blog is meant for documenting my journey of my current ongoing work on porting my samsung galaxy tab A7, codenamed : gta4l to postmarket OS.

First, i would define some terminologies that basically defines the whole underlying technology that makes android different from mainstream Linux based distributions. Starting from bootloader and partitions, most of the desktop os, lets you define partitions that includes a UEFI/BIOS partition, / (root partition), and an optional swap partition. This is usually a common use pattern, though a user can split the partitions based on utility, like creating a separate tmpfs, if a machine has low memory and is suited for a compilation heavy environment. A separate /var if intended for a mail server. But android intended for handheld devices works in a heavy environment of embedded systems. Thus it includes multiple partitions that holds binary blobs for hardware like camera, flash light, speakers and multiple such embedded hardware. Another example being bluetooth, Android uses its own bluetooth stack (Fluoride/Gabeldorsche), talking to hardware via a vendor HAL. Whereas pmos uses bluez. As linux distributions expect every code to exist in either the kernel or as loadable modules, this behaviour creates conflicts, and so lot of times peripherals just don’t work in pmos. While BlueZ,which talks to hardware via HCI (Host Controller Interface),the standard protocol. The chip itself speaks HCI regardless of OS. Therefore when a utility/software requires a camera access, the android kernel consists of the device driver, that has the ability to interact with the binary blob (firmaware) situated in the partition, these drivers then pass on the control to the binary, which performs the action. Other than that android has another defining concept of slots, older devices and even many lower end devices make use of single slot mechanism (A slot), while latest and higher end devices make use of dual slots (A/B) to manage upgrades.

While in general the android environment seems more inaccessible to changes compared to desktop counterparts, its actually the opposite. Android devices lets a super user have complete access including the bootloader, which if undergoes modification or accidental deletion makes the system unbootable, commonly referred as “hard bricking”. While soft bricking is recoverable, which includes flashing the wrong boot image. But scenarios exist where hard bricking is possible if a user flashes a wrong recovery and boot images. MOst important defining concept in android ecosystem being three images, vbmeta, dtbo, recovery.img and boot.img. vbmeta checks for signature of boot.img, so if a wrong/unrealted device boot.img is flashed, android will refuse to boot and will take to recovery partition. Next comes dtbo, which is a binary file, produced from dts (device tree source), it defines how the entire board is defined on the SoC(System on Chip). As android being part of embedded system, it is meant to be space efficent. This dts tells the kernel, how the board is defined, which peripheral is connected to which port. As Linux kernel is highly portable, it runs on many embedded hardware, so the concept of dts is not alien to the OS itself, the issue lies in dts naming conventions.

Here, I will define two kernel sources, upstream and downstream. Upstream being the latest branch of linux kernel or a kernel compatible with kerenl.org’s releases. Whereas downstream being the AOSP based kernel shipped by the vendor. So the dts file structure defining is what decides portability. Understanding of the device board thats slapped on top of the SoC is crucial.

So to get the images, kernel source tree and dts files(though most of the vendors rarely release this, vendors mostly try to release as less as possible without violating the GPL licenced parts of Android). Well we can always extract these images from a running system using adb(android debug bridge). Most vendors have a dedicated channel for releasing these software components, here we are trying to port a samsung galaxy tab A7, model : SM-T505, device codename : gta4l. For samsung the dedicated release channel is :

https://opensource.samsung.com/

As I’m running Lineage OS currently on this tablet, its comparatively easier, as I can get all the sources from Lineage’s git repo. This also has a massive advantage, that everytime I need not rely on odin/heimdall instead I can use fastbootd.

https://wiki.lineageos.org/devices/gta4l/
https://github.com/LineageOS/lineage_wiki/blob/main/_data/devices/gta4l.yml

The gta4l.yml file contains device specification and Lineage maintainer details, as Lineage provides complete working custom ROM for official devices, these config are highly reliable source.

For now the priority is to get a bootable image with display and touch sensors working, once we get to that stage, next focus would be on audio, bluetooth and getting a complete desktop environment working. From the yml file, the SoC is “Qualcomm SM6115 Snapdragon 662”.Thats clearly a good thing, because a SoC based on Qualcomm is most likely to have the device tree in linux mainline kernel, unlike mediatek which seems to be bit opaque or rather say uninterested. So here I will list all the links that I will commonly refer to create and understand valid dts files and as well as look into its sibling devices that may be supported.

https://wiki.postmarketos.org/wiki/Samsung_Galaxy_Tab_A7_(samsung-gta4lwifi)
https://wiki.postmarketos.org/wiki/Qualcomm_Snapdragon_460/662_(SM4250/SM6115)

Though pmos doesn’t list any active user for T505 itself, but its sibling the gta4lwifi has some work in progress, which is a good sign. So now we setup the pmbootstrap , which is the central command-line application for postmarketOS development. Among other things, it allows building packages, creating installation images and flashing them to your device.

Installing pmbootstrap from GURU repository in Gentoo:

sudo emerge -avq dev-util/pmbootstrap

pmbootstrap working directory is

$HOME/.local/var/pmbootstrap/cache_git/pmaports

Also I will create another directory in my home, to have easy access to the source files and organising the project directory

mkdir ~/postmarketos
cd ~/postmarketos

The above selections are based on my preferences, iwd is modern and integrates better with systemd, I choose pipewire because it was designed with bluetooth in mind from start, and bluetooth is a must for me. The above extra packages are for basic utilities like vim and nano for text editing, dropbear for a lighweight ssh client, strace syscalls a process makes, highly useful when a daemon fails silently without providing any errors.

strace daemon_name     # shows what a daemon is doing at kernel level

evtest reads raw inputs from /dev/input/event* devices, evtest detects if kernel is receiving any input before any UI layer is involved.

After pmbootstrap init completes, check the status.

For now this looks fine to me, also above I choose fastboot as flashing method rather than heimdall because my device currently runs lineage os, so I do have access to userspace level fastbootd, which is much simpler and faster. Though in most cases heimdall should be preferred because its intended to be used for samsung devices,as samsung devices use their own odin protocol.

So here we are done with the initial setup, and we can now setup the working directory to clone the mainline kernel, install any required packages, inspect the device partitions and extract the dts files. Though for my device I can simply refer to the LineageOS tree, I will include every option that might be useful for future use cases. Now we need is adb and the device to be ported need to have debugging enabled in developer options. Also great to have rooted usb debugging to be enabled, by default LineageOS ships with this option enabled in its kernel.

Now we can extract the dtbo image

I’m not pasting the heimdall print-pit output, because its not viable here, but we will extract it and it will remain a good source of comparison

heimdall print-pit

Now we need to clone some important repos, for reference, the device tree from lineage and the android kernel common to the snapdragon 6115.

git clone https://github.com/LineageOS/android_device_samsung_gta4l
git clone https://github.com/LineageOS/android_kernel_samsung_sm6115
git clone https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git --depth=1 --no-checkout

# Also as this a work spanning across months, its reccommended to run "git pull" once a while to ensure we are working with the latest developments.

I would end the part-I with referencing fastboot, adb and heimdall sources, also providing some essential commands.

Official docs:
https://developer.android.com/tools/adb

Source:
https://android.googlesource.com/platform/packages/modules/adb
Official docs:
https://developer.android.com/tools/fastboot

Protocol spec:
https://android.googlesource.com/platform/system/core/+/refs/heads/main/fastboot/README.md

Fastbootd (userspace fastboot) specifically:
https://source.android.com/docs/core/architecture/bootloader/fastbootd

Official repo (Henrik Grimler's maintained fork):
https://gitlab.com/BenjaminDobell/Heimdall

https://gitlab.com/BenjaminDobell/Heimdall/-/blob/master/README.md 

Flashing guide:

Samsung specific:
https://wiki.postmarketos.org/wiki/Samsung_Galaxy_flashing

Samsung Odin protocol (Heimdall is its open implementation):
https://wiki.postmarketos.org/wiki/Odin

PIT file format:
https://wiki.postmarketos.org/wiki/Partition_Information_Table

Android protocol, runs from recovery (fastbootd) requires LineageOS recovery to be present, Samsung removes it from their vendor distributed/ stock ROM Fastboot operations-(top choice)

fastboot getvar all          # reading partition table
fastboot flash boot boot.img    # flashing boot image
fastboot flash recovery recovery.img  # flashing recovery image
fastboot devices  # device detection
fastboot reboot
fastboot reboot recovery
fastboot reboot bootloader    # reboots to download mode 
fastboot get_staged dtbo.img   # needs inquiry from my end
fastboot flash --read dtbo.img  # needs inquiry

Fastboot doesn’t support reading partitions(This oeration is like extracting images and not to be confused with reading partition table, which gives the info of disk structure)

Heimdall is reverse engineered based on Samsung’s Odin protocol, Download mode, always available at hardware level, independent of installed OS Heimdall operations

# Needs to be in download mode, or else heimdall operations don't work.
heimdall print-pit   # print partition-table
heimdall flash --BOOT boot.img   # flash boot partition
heimdall flash --RECOVERY recovery.img    # recovery partition
heimdall download --BOOT lineage_boot.img   # extracting a partition
heimdall download --DTBO dtbo.img   # reading dtb partition, heimdall cannot extract dtb from a live running kernel, only adb can do so
heimdall detect   # detect devices

Android Debug Bridge, normal boot or recovery requires USB debugging enabled or recovery ADB

adb root
adb pull /dev/block/by-name/boot lineage_boot.img

# adb with su
adb shell su -c "dd if=/dev/block/by-name/boot of=/sdcard/boot.img"
adb pull /sdcard/boot.img lineage_boot.img

# extracting dtb fom live running kernel
adb pull /sys/firmware/fdt gta4l_extracted.dtb

# ADB with root
adb shell su -c "dd if=/dev/block/by-name/DTBO of=/sdcard/dtbo.img"
adb pull /sdcard/dtbo.img .

adb devices # device detection

With this we have setup the toolchain required, and this will mark the end of Part-I from my end. I’m planning to actually write next on the detection of board configuration from the gta4l tree. Then gather more sources on dts writing conventions of android and linux. After that we will start writing the dts file for mainline linux kernel, for which we will consider a reference device listed on linus branch, as there are devices that make use of 6115.dts

My idea is to divide the components or peripherals in a hierarchy/priority p1.Critical-like ufs storage, serial console and usb p2.usability-touchscreen, display, power keys,.. p3.connectivity-wifi,bluetooth,modem,.. p4.supporting cast-regulators,cast,..

Well its already too long,I shall close it here.

Thankyou !
