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.
We are in the midst of the Linux 5.8 merge window so there is no new
-rc version to rebase on. -rc1 next week is also not the perfect choice
for a release (first rc is usually still a bit unstable).
On the other hand the changes that landed the last few days are quite
nice and ready to go, so I decided to rebase on a stable kernel release
(5.7.1). Not sure if I'm ever going to do this again :)
Changes:
- Update to Linux 5.7.1
- bq-paella: Add sound and modem
- Enable some new kernel options for DB410c
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
dbus-launch doesn't get installed automatically. On the other hand,
dbus-run-session does. This version ensures that dbus is also launched
for the graphical demos
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
a5lte and a5ulte are almost identical hardware-wise, the separate
package is mainly necessary because they use different firmware
signatures.
Alexey Min agreed to do some testing occasionally :)
I noticed that the Samsung i9003 is actually a heimdall-bootimg device.
But at the same time, the kernel is assembled as if it is isorec.
[ci:skip-build]: already built successfully in CI
Update to a new kernel based on v5.7-rc6, adding the following new
features:
* Remoteproc support and firmware loading
* Panel drivers for OnePlus 6/T
* Adreno 630 support
* Anbox support
The new firmware-oneplus-sdm845 is required for these features and
devices will not have working display output without firmware
[ci:skip-build] Already built on CI
It is possible for msm-modem to get installed before
rmtfs-openrc, which causes the following error in
post-install:
* rc-update: service `rmtfs' does not exist
ERROR: msm-modem-1-r0.post-install: script exited with error 1
Add a dependency to ensure rmtfs-openrc gets installed first
Generating a sparse rootfs speeds up flashing through Fastboot.
Also change some bootimg offsets to be more accurate to the one
actually used by the bootloader. (They will actually just be ignored,
since the bootloader always uses its own hard-coded ones.)
Make voice call audio work out of the box by starting q6voiced on
all installations with the modem. It might be nice to start it only
when oFono is installed and enabled, but q6voiced is quite minimal
so it does not seem worth the effort.
linux-postmarketos-qcom-msm8916 now supports voice call audio.
However, at the moment the audio stream needs to be explicitly started
by opening some PCM audio devices when the call is started
(even though no audio data is written to the PCM device).
Eventually this should go away by implementing codec2codec support
for q6voice in the kernel. In that case, the stream would be started
once the audio routes are set up using ALSA UCM. However, this is a bit
complicated actually so for now it's nice to have a workaround:
q6voiced listens on dbus for signals from oFono, and opens/closes the
PCM device when a call is initiated/ended in oFono. This essentially
makes voice call audio work out of the box (provided that the audio
routing, e.g. Earpiece and a microphone is set up appropriately).
