Hey, does it work Android 2.1 roms? Also, what cpu governors are supported?

It works with the majority of all Android ROMs. Sense can be annoying though (especially usb-tethering).
Governors:
- Performance
- Userspace
- Ondemand
- Interactive
- Conservative
- Smartass v1
- Smartass v2

@gkiller, ok, gonna check it out when I come back

Zero problems with mounting sdcard here. ICS 4.0.3 w/ lv 1.1.

thank you for your work Riemer. Happy to test this with ICS rom & include it in it if that's ok

@gkillerx I'll try to get zram working today.

Last night I have been trying again to get a 2.26.38 working on our hero's, but it seems I can't find any appropriate yaffs2 drivers for it. The current 2.6.38 corrupts the /system/ partition, while the current .35 ones don't work on the newer versions (interface changes). Guess there is no other kernel dev around willing to help?

Rewriting them would take a lot of time

Hi riemervdzee,

I encounterd an other problem. The music player randomly freeses and I also lose my GSM connection then. This happend 2 today but it happend when I was driving so I coudn't do dmesg....

I just arrived home but that was 3 or 4 hours later so I decided to try and replicate it at home and it happend again and this time I got the kernel dump. But GSM showed that it had a connection but the music player just froos. in the status bar it showed the song that was on but there was no sound and it was playing 0:00. I had to pause the song, playback (to 0:00 lol) and it started again after pushing play.

I also got the not mounting in it (mount and nothing happend). I also tested the kernel (v1) on 4.0.3 and there I had no problems with mounting.

Attached is the kerneldump. Hope it helps you!

All these problems happened under which ROM? It seems the music app got killed, probably due low memory. Maybe the ROM has the mem killer tweaked badly?
I always found the AutoKiller handy, so you could set the mem tweaks from an app (and it has more tweaks).
Did they also occur under the ICS 4.0.3 one?

I find the music app which is included really unstable. Try another musicplayer instead, I use ^3 (aka Cubed) from play store

Edit: Was the music issue on ICS?

gkillerx · May 2, 2012

Rom is:
http://xdaforums.com/showthread.php?t=1003381

With no task killers or supercharger script.

I have no idea if this also happens on ICS because I coudn't test this.
I do know that when I install flykernel there are no problems

While I would love to help out on the Eris side, I'm far from being a kernel dev and right now just trying to catch up and learn enough to get a .35 kernel going for the Eris. Very appreciative to have your source along with jaybob's for heroc to look at and use.

I switched to the ROM to test the problems out, did the following:
1: flashed the ROM just let it boot. Mounting usb ofc works (due the flykernel)
2: Flashed LV 1.1, just let it boot again. Mounting usb doesn't work of course as I didn't wiped dalvik.
3: went to recovery again, wiped dalvik, booted the bugger and usb just works.

Are you sure you wiped dalvik after installing LV? I think the other "strange" bugs are related to not wiping as well.

Is the .35 version already working for the Eris? I always love to help you out if not. I'm thinking of dropping 2.6.38 for now, as I have not enough time to write a whole new yaffs driver. So, any new project is always welcome hehe

Got g-talk or something? mine is: riemervdzee@gmail.com

I started testing LV 1.1 today with Elelinux-7.2-Hero-v3.8 Android 2.3.7. I was curious if the gps-reboot would be gone. So far I haven't seen it

Thank you again Riemer. I never thought I would get rid of that damn bug.

Yep offcourse I wiped it. I'm flashing kernels now almost twice a week (TF101) So I know my way around flashing kernels

Meby it's just my stupid phone that is just slowly dieng out or that I have a simcard putted in ?

Try removing dalvik-cache manually. Go to recovery and open an adb shell:
mount data
rm -rf /data/dalvik-cache

I'm sure it is a dalvik cache problem. Which recovery are you using? Note that wiping cache doesn't work, as dalvik cache is stored somewhere else

Cheers, R

Yeah, if dalvik sits in sd card it will not be removed even if you select wipe dalvik-cache through recovery.

Uhm oké I checked my phone and found dalvik-cache on the following places:

/data/dalvik-cache
and also:
/system/sd/dalvik-cache

I guess the last one is my sd-ext partition? I'm using RA-HERO. So are they both used?

riemervdzee · May 3, 2012

I just checked the install scripts and /data/dalvik-cache "symlinks" to /system/sd/dalvik-cache (only when you have an ext partition of course). Symlink = Symbolic Link, http://en.wikipedia.org/wiki/Symbolic_link
This way the Android system still thinks the dalvik-cache is located at /data/ and can access it in a normal way, but underwater it is stored on the SD ext partition.

You can view the symlinks with "ls -l". An example would be:
lrwxrwxrwx 1 0 0 17 May 2 22:12 d -> /sys/kernel/debug

where /d/ is a symlink to /sys/kernel/debug/

Removing dalvik-cache under recovery, would delete the symlink reference only but not the contents on the SD ext partition. Simply because the ext-partition it ain't mounted under recovery (it is done via the init.d script).

Also.. I ain't sure it is safe to remove the dalvik-cache when the system is running, while removing it under recovery might be troubling as you have to mount the ext partition of your sd-card.
Which recovery are you using?

Edit: Small mock-up what you could write under recovery (via adb shell):
mount -o noatime,nodiratime -t auto /dev/block/mmcblk0p2 /sd-ext;
chown 1000:1000 /sd-ext;
chmod 771 /sd-ext;
rm -rf /sd-ext/dalvik-cache;

Thanks for the support so far

As mentoined befor, I use RA-HERO as recovery img.

So to be clear. If I run those commands in recovery adb shell it should remove dalvik-cache completely?

I guess I also have to do:

Code:

mount data
rm -rf /data/dalvik-cache

The commands I gave you, should work aye. make sure the mount command returns no error though. No need to rm /data/dalvik-cache btw.

gkillerx · May 3, 2012

It worked, so far so good! Just played music and did stuff on the phone (send emails, and read whatsapps.) and no problems so far!

Thanks for the support so far

edit:
still having USB mounting issues

Edit2
Still having problems with playing music. When i am sorting music for a playlist it hangs, music stops and all my music is getting deselected! Argghhh stupid music! Kernel is sweet fast and snappy. I also tried supercharging but still same problems. I have 500 music numbers.

riemervdzee · May 4, 2012

Guess it ain't cleared correctly.. I suggest either a fresh install, or I can modify the scripts ele uses to get the dalvik on /data/ again, might be easier to wipe it in the future as well
