wileyfox-crackling was the only user of QCDT. Now that it is also
using appended DTBs, there is no need to generate the QCDT image anymore.
Another advantage of this is that mainline can then be only booted using lk2nd
(as intended), since booting it from the stock bootloader has weird side effects
(e.g. no WiFi/BT MAC address set).
That path works just as well as documented at
https://doc.qt.io/qt-5/qstandardpaths.html (GenericConfigLocation) and
it doesn't depend on the user being created after the package has been
installed.
polkit rely on systemd, so we don't get correctly working setup.
This impact non-working backlight control from userspace and other
stuff.

At the moment we store the same initramfs-extra twice on the file system:
- /boot/initramfs-<flavor>-extra
- /var/cache/postmarketos-mkinitfs/initramfs-<flavor>-extra_<hash>
The second copy is exactly the same file, just with the <hash> (for caching)
appended to the filename.
We can avoid this by appending the hash directly to the filename
on the boot partition, i.e.
- /boot/initramfs-<flavor>-extra_<hash>
This is possible because we only reference initramfs-extra from the main
initramfs, and we already replace the path in it dynamically.
It will just let the main initramfs load -extra_<hash> instead of just -extra.
This saves a few megabytes of disk space on the rootfs.
postmarketos-ui-sway already depends on xorg-server-xwayland for
X clients. There is no need to pull in the entire X server including
all necessary drivers.
This saves ~84 MiB of disk space when installing postmarketos-ui-sway
on asus-me176c. X applications are still working fine through Xwayland.
Also remove explicit dependency on dbus - it is already pulled in
by dependencies like lightdm or elogind and nothing in
postmarketos-ui-sway depends on it specifically.
We need to generate the splash screens separately for each device,
because they are specific to the device's display resolution.
At the moment we do this dynamically during the installation process.
This has the advantage that there is no need to re-build all device
packages when one of the splash screen is changed (or a new one is added).
In reality, however, the splash screens do not change very frequently.
On the other hand, generating the splash screens dynamically has signficant
disk usage overhead for a minimal ("none" UI) rootfs:
The Python interpreter together with the necessary libraries requires
about ~60 MB of disk space on aarch64.
The splash screens itself require about ~100 KB for 720x1280.
This is not necessary if we move the splash screen generation into
devicepkg-dev, which is used to build the device package for all devices.
Another advantage is that we no longer need the (rather complicated)
caching mechanism for splash screens - so we actually end up with less
lines than before.
rootfs size for samsung-a5ulte ("none" UI):
Before: 450M
After: 388M (-62M)
After this change, every(!) device package needs to be rebuilt once.
No changes are necessary in device packages.
Kernel subpackages may contain a "-" (e.g. -kernel-mainline-modem);
replace it with an underscore to make sure that we find the
kernel-specific variables in deviceinfo.
If (a) the kernel command line parameters include PMOS_BOOTCHART2 and
(b) /sbin/bootchartd exists (i.e., the bootchart2 package has been
installed), run /sbin/bootchartd instead of /sbin/init.
Port bootchart2 to PostmarketOS, with three patches:
1. Modification of /etc/bootchartd.conf so that the collector
will stop after sshd has started.
2. Python 3.8 compatibility
3. Disable the interactive mode of pybootchartgui.
Use bootchart2 to profile system boot or a running system.
1. Add the bootchart2 package to your device.
2. Add the following kernel command line parameters: initcall_debug
printk.time=y quiet
3. To profile system boot
a. add the following kernel command line parameter: PMOS_BOOTCHART2.
This parameter causes mkinitfs to start /sbin/bootchartd instead of
/sbin/init. /sbin/bootchartd then starts /sbin/init.
b. (optional) modify EXIT_PROC in /etc/bootchartd.conf to define
when the collector is to stop.
c. Boot the system. Approximately 20 seconds after sshd starts
(if using the default value of EXIT_PROC), the collector
will exit.
4. To profile a running system
a. use the command '/sbin/bootchartd start' (as root) to start
profiling
b. use the command '/sbin/bootchartd stop' (as root) to stop
profiling
5. When the collector exits, /usr/bin/pybootchartgui will create
a visualization in /var/log/bootchart.png.
- Update to Linux 5.5-rc4
- Fix freeze/crash when accessing reserved memory on Samsung devices
- This happened e.g. when doing large eMMC writes
because the disk cache filled all available RAM.
- Fix SD card detection on samsung-serranovelte
- Disable UHS-1 modes since they appear to be broken in hardware

Comment out the initstepslew line in /etc/chrony/chrony.conf.
initstepslew can delay booting while chrony sets the time. The
makestep 1 -1 line in the configuration also causes chrony to step
the time (whenever the offset is greater than 1s), making
initstepslew redundant.
Unfortunately, early firmware versions on MSM8916 (used together with
Android 4.4) are not capable of booting aarch64 kernels. MSM8916 was
Qualcomm's first 64-bit capable CPU, and back when it was introduced
Android did not even support aarch64 yet. So the aarch64 capable
hardware was usually used together with armv7 binaries.
To make things worse, this firmware is also signed (usually per-device),
making it (currently) impossible to update it without help from the manufacturer.
This means that we are currently unable to run mainline on devices
that never received an update to Android 5.0
(e.g. the Samsung Galaxy S4 Mini Value Edition).
One way to circumvent this limitation is to build mainline for armv7.
This works surprisingly well with some additional fixes.
Devices with this firmware limitation are still unable to use aarch64
binaries, but at least we can run mainline on them!
- Rebase on Linux 5.5-rc3
- Add display, touchscreen and GPIO keys for samsung-gt510wifi
- Add vibrator for wileyfox-crackling
- Zinitix touchscreen improvements (used in samsung-a3ulte)
- Upstreamed several patches
Current default is performance, and that is for sure not a great choice
for battery. We can experiment with ondemand as well, but based on docs,
conservative is recommended.

On some devices a getty should run on the serial console.
Configure the getty by setting the deviceinfo_getty variable. The
format is "<port>;<baud rate>". For example, "ttyS0;115200".
A post-installation trigger in postmarketos-base checks
/etc/deviceinfo, and modifies /etc/inittab if the device should run
a getty.
