Call for testing: Google/Huawei Nexus 6P (angler) owners

@Flohack
, I've had the sound dropouts when the phone have been in my pocket. I'm not able to reproduce the issue. Maybe you fixed it with the latest image. I had this issue during the week, at work. -
@Flohack the problem with the sound persist. It effects clockalarm, incomming call and reminder alarm from the note app. It accuars when the phone has been hibernating for a while. Should someone call me now or an alarm would start when I am using the phone, the sound would work without any problems. Should I reflash the system.img?
-
@Rondarius No, that won´t help. Lemme try this out, I will leave the phone sleeping and then let someone call me resp put a few alarms inside.
Note I am on holiday now for 2 weeks, so I will not actively work on anything xD

So back from holiday
One thing I noticed is that when using the phone actively it kinda sucks out hte battery quickly - probably due to all 8 cores getting enabled. I would expect that Android does not fire up all cores everytime the phone is unlocked. Does anyone of you have experience with the power management under Android on this device?
-
@Flohack hope you enjoy your holiday.
i guess for android only ARM Cortex A53 cores workes when you use non-performance apps.for me i use only 4 cores due to BLOD i can confirm that the experience in term of battery is almost the same as android. so i think you are right, 8 cores working at the same time consumes the battery .
-
@Flohack That is the way it worked on android with the N6P. Four cores on all the time, + four additional cores when needed. I thought it would work the same way naturally with UT on top the android stack, but I guess not. I haven't taken mine out anywhere because of covid, so I haven't used it enough to notice.
-
Well this is intetesting. Just did a bunch of app updates and now my bluetooth works again.
-
Libertine tweak tool now available for arm64. Hooray!
-
i patched a 4 core image from the last halium boot image using Android image kitchen for blod (4 cores) users

@rocket2nfinity No unfortunately I suspect its not working naturally. The kernel needs to know a) which of the cores are the big ones, and b) even if they are idle, dmesg logging tells me that all are being woken up. I think thats the problem, the scheduler is missing in Linux/Ubuntu to handle this correctly. Desktop Linux never has to deal with cores of different power probably. Plus its kernel 3.10, even if there is support for that its unlikely to be in that old kernel.
But, on the other hand, Android cannot handle this much differently than in the kernel. I am confused. need more observations.
-
@Flohack Took mine out today, specifically to see if it consumes battery excesively. Yes, it seems all 8-cores are going all the time, and it does drain faster than it used to.
Do have another question.... Is there a way to get visual voicemail messages to actually show the message, rather than the code script that pops up letting me know there is a visual voicemail message?
-
@rocket2nfinity Ok so lets monitor this a bit...
I am not sure what you mean by that voicemail messages thingie. Can you send me a screenshot?
-
@Flohack Phone number blacked out....
-
@rocket2nfinity this is from messaging app? Its not an issue of the porting to 6P, but a general issue for the operating system, you might want to file this on the main Github tracker on github.com/ubports/messaging-app - I have never seen such a thing before though
-
@Flohack Yes, i'm pretty sure it's just the messaging app is not programmed to know what to do with this type of message. It happens with messaging apps on android AOSP and other roms as well.
I blocked out the phone number because there are services on the web that will display the actual visual voicemail message for you if you input the script I posted.
I will open a feature request on git.
-
@Flohack I stumbled on an article that might shed some light on how to enable/disable the 4 performance cores. In the middle of the article, with associated links to xda-developers, is code for how XCnathan32 figured out how to recover from the BLOD on the N6P and how the 4 cores are employed in android.
Beyond my skills, but hopefully it will give you some ideas about how to do power managment on the N6P.

@rocket2nfinity
He modified the boot image .
to be specific init.angler.rc file which usally can be found at ramdisk folder.
the file does not exist in the halium boot image i don't know why. -
@rocket2nfinity Yeah I know about that, I am actually doing the same when providing a 4-core boot image here. Its done with a kernel cmdline rather than init.rc magic, since the kernel otherwise tries to also start the 4 big cores.
Unfortunately the thing is a bit more complex, Google used cpuset structures to group the tasks that should run on either big or little cores, but the Ubuntu Touch processes are different ones, so it might be needed to find a new cpuset description to balance the load. On top of that, cpuset seems to be ignored by the kernel, probably its a permission issue ^^
-
@Flohack If you had the user to choose which cores to use during installation or a setting in the settings menu? How long would the the battery last if you used 4 small cores, 4 big cores or all 8 cores? I know it is a little dirty but this could be an option during the time needed to solve the battery drain.
