This is the downstream u-boot port for the Galaxy S2.
The load script has been slightly altered to load the kernel from the
KERNEL partition at the 512 KiB offset, instead of loading it from the
RECOVERY partition, since PostmarketOS places the second initramfs in
the RECOVERY partition.

Newer Qualcomm SoCs (e.g. SDM845. MSM8953) seem to use a different
method to talk to the modem. There are no longer separate rpmsg/SMD
channels for QMI messags, instead the modem is also available through QRTR.
On these newer SoCs, installing msm-modem-mainline is pointless,
because the created /dev/modem device will not actually allow
communicating with the modem. However, you still need the part from
the base package (msm-modem), which installs+enables rmtfs.
To avoid confusion, rename the msm-modem-mainline subpackage to
msm-modem-rpmsg. Install only "msm-modem" on SDM845 because that
likely does not allow communication with the modem through RPMSG
anyway.
This upgrades the librem5-base config used to v21:
- better headphone support/detection
- enable runtime PM for usb/SD interface
This also removes the modemmanager subpackage, the udev rule that was
installed by that package is now in modemmanager in Alpine.
This upgrade includes:
1) enabling fb in deviceinfo: This was previously disabled for
debugging purposes, but can be re-enabled now so we get the
awesome postmarketOS splash screen!
2) fixing GPS, kinda: the device has changed, so this fixes the gpsd
config to use the correct device, and includes a udev rule to
make sure the device is owned by a group that gpsd can use
3) usbnet working with configfs
4) disables getty on /dev/ttyGS0, this was usb serial but isn't
configured now that this uses configfs
5) uses Mesa from Alpine, instead of mesa-git in pmaports. Upstream
Mesa has support for the vivante gpu, and no longer need to rely
on mesa master branch for support.
6) fix pulseaudio detection of profiles
7) update the librem5-base version used, includes a udev rule to
configure DDR freq governor as 'powersave' (reduces power, and
how much heat this thing puts out)

In the Linux kernel, the ST-Ericsson NovaThor U8500 SoC is barely
ever mentioned under the "NovaThor" name, more common are names like
U8500, Ux500, ST-Ericsson, STE, ...
Let's rename the kernel package to linux-postmarketos-stericsson
to make that more clear. Also cleanup the APKBUILD a bit while we're
at it, HOSTCC is unneeded, remove unnecessary depends, ...
bq-paella allows running unsigned firmware from other devices.
We can use that advantage to replace some of the original firmware
with newer versions from other devices. The DB410c has updated WCNSS
firmware that reportedly improves WiFi/BT coexistence (i.e. behavior
when both WiFi/BT are active at the same time).
Depend on the virtual "firmware-qcom-msm8916-wcnss" package to give
the user the choice which firmware version they would like to run.
The newer version from "firmware-qcom-db410c-wcnss" is installed by
default (since it has a higher "provider_priority"), but the user
can choose to replace it by running "apk add firmware-bq-picmt-wcnss".
Following discussions in
https://gitlab.com/postmarketOS/pmaports/-/issues/398, swclock has been
removed from postmarketos-base to avoid setting time incorrectly on
devices with a hardware clock. The various raspberry pi don't have
an hardware clock. This activate swclock back.
This adds a hwdb override for the trackpad that fixes the reported size, this fixes
the acceleration profile and palm detection in libinput.
Pulse now follows alsa paths for ucm files so the path for the rk3399 ucm has been
updated to match.
The DB410c is a SBC with APQ8016 SoC. It runs on mainline without
any patches. This port makes use of the existing linux-postmarketos-qcom-msm8916
kernel package that is used for other mainline MSM8916 devices.
Tested functionality:
- USB Network, USB Host (e.g. an USB keyboard)
- Flashing (Fastboot)
- Display (HDMI)
- WiFi/BT
- GPU
- Audio (HDMI)
- FDE
Not tested:
- GPS
Note: The firmware package is called firmware-qcom-db410c (instead of arrow)
because the firmware is provided directly by Qualcomm, not Arrow.
Newer versions of alsa-lib now require a top-level ALSA UCM
configuration (/usr/share/alsa/ucm2/ucm.conf):
ALSA lib parser.c:2159:(load_toplevel_config) Unable to find the top-level configuration file '/usr/share/alsa/ucm2/ucm.conf'.
ALSA lib main.c:983:(snd_use_case_mgr_open) error: failed to import hw:0 use case configuration -2
alsaucm: error failed to open sound card hw:0: No such file or directory
The upstream ALSA UCM configurations are provided by Alpine's
"alsa-ucm-conf" package, so make sure to install it additionally.
What works:
- Booting
- Display
- Touch
- USB Ethernet
What doesn't:
- Sound
- Wi-Fi
- Modem
- Camera
(NOTE: If the display doesn't work, try flashing your phone back to stock, then trying again.)
bq-paella has an external speaker amplifier connected to the right
channel of the headphones output. Add an extra UCM configuration
to handle this properly.
Just got done with my second port of postmarketOS, here's the device:
Amazon Fire 7 (2019) postmarketOS
Mediatek MT8163
600x1024 display
1GB RAM
Linux 4.9.77 (downstream kernel)
Untested:
- Wi-Fi
- Audio
Pretty much everything else
Works:
- Boots
- Touchscreen
- Battery percentage seems to show in Xfce
I cannot test on most of them (at the moment), but I was involved
in porting all of them so I could "guess" certain changes at least.
[ci:skip-vercheck]: just moved and some maintainers
