Good morning, I have noticed there is an abandoned port of UT for the Galaxy S5 and also a WIP port of postmarketOS to the Galaxy S5. I would like to begin reviving the Galaxy S5 port of UT myself. It was such a powerful phone especially for its time and deserves the full Linux treatment.

Before spending time and ressources in the long run of porting, beware that a device must be able to support Ubuntu Touch 24.04 to be viable in long term.
That means minimum Linux Kernel version required.
16.04 is deprecated, and 20.04 is a step to 24.04 and will be left behind
whennow 24.04 is stable. -
There is a build of LOS/Halium for Android 13 so kernel and Halium should not be a problem.
-
Poking around a bit more, I think the standalone kernel method should work on the S5 since it's on mainline. Gonna try that route.
-
Starting a test compile of mainline LOS 18.1 atm
-
@Keneda Are you aware of an existing device tree in UT for the S5? I can only find kernel and halium-install sources for S5, not rootfs sources.

Mainline kernel for S5, just for reference
-
Found a valid deviceinfo file we can use with minimal edits from the postmarketOS downstream kernel
-
@Keneda should we prefer mainline kernel or pmOS kernel?

Receiving this error while trying to build mainline for S5 using breakfast/brunch, system appears to be complaining that it can't find the device tree although I just posted the device tree both in mainline and pmOS above. This is honestly not behavior I've ever witnessed from breakfast/brunch before...
-
Kernel compiles and boots! Added necessary Halium config files, next step is compiling rootfs. I still can't find rootfs source for the S5.

@tenbucket
I'm not a porter at all and don't have knowledge about such things.
You should try telegram halium group given in the thread I put link above. -

@tenbucket why do you call it mainline? Its version is very old, 3.4.113. Mainline usually means what Linux upstream is
-
@faveoled I should say "used to be mainline"
-
@faveoled "True mainline" 5.2 is being tested by the pmOS team ATM. It compiles and boots however there are missing modules.
-
Can anyone help me merge drivers and modules into Android kernel 5.2 "true mainline"? I can theoretically do the work on my own but I have an obligation today and it would take a long time on my own anyway
-
We are ready for merge to "true mainline" Check the GitHub repo. I need someone with merge acces to mainline to perform the merge for me.
-
@tenbucket
Again you should go on the halium telegram group.
Forum is more for reporting port state and find tester in community and get feedback from them than for finding porting help. -
@Keneda My apologies, I'm used to pmOS forums, been developing for them for several years now
