Re: [ROM] CM10.1 AOSP 4.2.1 Jellybean [KANG] [Feb-12]

Yeah, that's gone. The changes I made in 99kernel all take effect when the phone boots, but at some random point (haven't managed to work out when but it takes an hour or so) the max CPU reverts to 1.566.

No-Frills' 'prevent other apps' feature does seem to stop this happening but it also prevents me from monitoring CPU speed with anything like Android Tuner so I can't be sure, also I'm not sure exactly how that feature works and it seems to be causing idle battery drain. Something is definitely changing it though and it happens with no apps installed that can change it or have root access, so I'm guessing it's something in the kernel.

The governor for cpu1 also doesn't seem to stick, it's meant to be badass and in Android Tuner it says it's using badass... until it switches on, then it flicks to ondemand. When it goes back offline, back to badass.

That just affects volume, as opposed to acid which changes a lot of audio configs.

There is a version of acid for our sensations though, just look in Sensation apps and themes. It's a modified version which I can confirm works fine on this ROM

OT: Hey albinoman, I've noticed cile has JDQ39 merged with his 4.2. From what I can deduce, I'm sure you could implement it in a future build ;)

I'm doubtful because this is after a full wipe and I think I disabled root privileges for all apps (or just uninstalled them), so unless it's SuperSU doing it I don't see how it could be anything else! I am still experimenting though, will let you know.

You'll be fine with the wire mod-- I've S-OFFed three different sensations with no issues (even arced a little one time due to static electricity, didn't hurt anything).

Try to find the instructions with the video gif-- it helps get the right timing (has to be DEAD on to work).

Also make sure you:

1) Touch something metal first to discharge any static you have (will throw off the procedure otherwise)

2) Don't be stupid like me and use an unshielded wire (like a paper clip)-- it defeats the grounding action and will burn up a lot of time. Use a shielded wire or use a paper clip and wear a glove-- took me over 2 hours my first time until I finally realized that. I don't think the instructions mention it, and although it should be obvious, it just didn't occur to me right away (and I'm an engineering student, lol)

[HTC Sensation] Incredible_Culp:
Frustrated!

Im posting in here because this is the ROM im using now.. and it mainly happens on JB Roms anyhow.

-- No matter what Rom i use ICS or JB.. No matter what Kernel i use.. My music keeps skipping. Its like someone is hitting 'play'.... then 'stop'... then 'play' again.. It happens when (i think) my phone hits a low frequency.

While listening to music, it'll be fine for awhile -- then i think (when the cpu goes into a lower state) the music starts to chop a bit... Then when i try to wake the phone, it takes a pretty long time for the unlock screen to show.

Ive tried a lot of different cpu settings-- highs and lows, different I/O's, and different governors.. No avail. .. ive even tried different music apps -- same thing happens

Ive cleaned out and formatted my SD card, i even made the partitions bigger via 4ext touch recovery.

* But this is the kicker * -- It only started doing this like a little over a month ago and ive been testing/trying different solutions ever since --- My phone has never done this before -- and i havent changed my *routine* of flashing either -- so idk what it could be.

Any solutions guys..?? I have the lastest firmware and have the 1.27 hBoot too -- just throwing that out there as well.

EDIT -- Im leaning towards an early stage of a bad battery perhaps..? I have the stock one.

EDIT2 -- Ive set the No frills CPU to "include deep sleep" which makes the phone not go in deep sleep.. Its been running fine so far.

You say this happens on ICS? Do you mean CM and AOSP ICS ROMs or do you include Sense ROMs too?

I know that Sensations don't (and may never have) lpa (low power audio) on CM and AOSP but it is available on ICS ROMs based on the stock HTC ICS release. See if audio playback works on a Sense ICS ROM. This can at least rule out a hardware issue.

Hello!

At first a big Thanks to albinoman for his work with this ROM! A really impressive work!

Im on this ROM for a few days (and builds) now and have to say its working nearly flawless.

I have seen two problems i want to tell you about:

1. The custom wallpaper sometimes disappears for me - like for some others too --> i think i will try a full wipe flash if i get some time

2. Soft reboots

I think i can reproduce them quite often by sending a few (up to 50) SMS to myself (im use "simple SMS Voting" from playstore), turn the display off during the sending process and leave the phone alone for a few minutes. I was able to pull a logcat from this, see attached zip-file.

Main problem supposed down below the line "I/PowerManagerService( 427): Going to sleep by user request..."

To the clock drift:

I dont get the clock drift issue, but have seen this in the logcat:

W/Settings( 690): Setting auto_time_zone has moved from android.provider.Settings.System to android.provider.Settings.Global, returning read-only value.

Perhaps it has an impact to this... i dont know...

[HTC Sensation] anderl78:
AW: [ROM] CM10.1 AOSP 4.2.1 Jellybean [KANG] [Feb-13]

Perhaps your sd-card... You can try this:

Make a folder in /data, for example /data/test. Copy a few music files into this folder. Change the permissions of the folder and files to rwx (to be on the save side). And try to play from there... If you don't get the skipping issue, its very likely your SD...
[HTC Sensation] ziaulh.ch:
There are only two players working with DSP effects. So if you dont suggest apollo then google play music is the only one with dsp. WIth others the sound is really low! So you might look forward to remove apollo?

Although I havent had a single problem with apollo until 12th build. I am flashing 14th to see how it goes. But whats up with the kernel setting problems? You are going to revert again? I always added vm swapiness to 0 manually in build prop and nused android tuner for IO read size. So its now one less app which is very good.

btw, one question for you. Have checked the tweaks android tuner has on build prop? like

debug.performance.tuning 1
mot.proximity.delay 25
persist.adb.notify 0
persist.sys.purgable_asset 1
ro.config.nocheckin 1
ro.home_app_adj 1
ro.lge.proximity.delay 25
ro.telephony.call_ring_delay 800
and some tcp buffer to increase connectivity

Re: [ROM] CM10.1 AOSP 4.2.1 Jellybean [KANG] [Feb-13]

I'm not talking about reboots, it's shutdowns even though I have done the battery tweaks and have a good battery. Maybe it doesn't like the undervolt? As soon as I flash Bruce's kernel it's stable again, but it's only been a day so I'll stay on the same rom build I'm currently on for a few days to see if it truly has cured it. On the 10th and 12th builds it's shutdown randomly at least once or twice a day so if it behaves now I'll know it's something to do with the kernel.

It seems feature-wise, but CM (and also PA, which I follow) stated on G+ that there are much more changes underneath than expected.

PA is already building test builds, but CM's base is more affected by this, so it might take a couple of days.

[HTC Sensation] anderl78:
AW: [ROM] CM10.1 AOSP 4.2.1 Jellybean [KANG] [Feb-13]

I have seen this too. As fas as i know pmem is used to manage memory shared between kernel drivers (gpu , but a few more too) and userspace.

Now a bit "wild guessing" :) : SMS send/receive uses so much memory that there is not enough available for other things - like for the gpu whats then causing our reboot... something like a memory leak in SMS (???)...
[HTC Sensation] kgs1992:
Is GPU Rendering enabled in Settings > Developer Options?

If yes, can you disable GPU rendering & try to reproduce this?

This is right, that device runs out of pmem, but I think the soft reboot is caused because of this:

E/SurfaceTextureClient( 444): getSlotFromBufferLocked: unknown buffer: 0xf70f00f0
F/libc ( 444): Fatal signal 11 (SIGSEGV) at 0xf70f00f0 (code=1), thread 460 (UI)

Which is not due to pmem running out, but because the buffer no longer exists & the pointer is pointing to an unknown location(I guess?).

If anyone knows something & can probably fix it, this is where it happens:
