Been flashing between a29 & a30. I thought I would try to play around with GPU settings with trickster app. Everytime I change the setting & apply it I get an instant reboot, it doesn't matter whether its a29 or a30, it still happens.. What gives? Any ideas?

Also, besides the OP, does anyone have a good link to a informative place/thread where I could learn the basic building blocks of knowledge needed to understand how kernels & their options work? Understanding the language would be a big help.

Liking the smoothness of a29, and battery life seems to be at about a25 levels. Great work!
[Nexus 7 Android Development] seandarcy:
running a30 on n7 3g with temasek v18.

In terminal emulator, if I try to open nano I get "Error opening terminal: screen".

Now

export TERMINFO=/etc/terminfo

export TERM=linux

solves this.

If I reflash temasek ROM, nano also works. It seems that a30 somehow unsets terminfo, which seems odd for a kernel!
[Nexus 7 Android Development] dstryrwiz:
I'm having trouble quoting what I'm responding to (from Metallice regarding Westwood+ ).

Well you technically did rename your kernel M-Kernel+, but I just wasn't certain with Westwood as although it was an improvement, I thought some people may have liked the old version so it was still incorporated to some degree. My mistake.

Suffering with a couple of random reboots with a30 and pa 2.99 b9.9jan12, usually when I've left it for an hour or so i come back to a rebooted device, but in the last 12 hours its rebooted in my hands twice. Using the same trickster mods as previous m builds cpu1.5 gpu600, slight mpu uv -25 and gpu @600 +50 to 1250, can someone tell me how to get the kernal error log msg to share?

Thanks

Don't. Just run your tab down and then charge all the way up without interruption. Then just use your phone as normal for a couple off charge cycles and then you will be getting accurate results.

When i was flashing my Huawei phone, battery calibration was needed when changing rom. I dont see that rule very often eny more.

What about tablets, is calibration even needed?
[Nexus 7 Android Development] FitAmp:
Battery calibration was never really "needed" it was always an optional step after flashing a new ROM. For me on my other devices, it really didn't show any difference at all. It just deletes old battery stats file so the system can create a clean new one. Making sure the battery is read properly. People state that they gain huge battery gains, in my opinion,I find this to be a placebo effect....

As i remember, when u charge the phone to 100, then unplug power supply and if the device shows other value than 100 it needs to be calibrated. But I didn't know, the battery stats resets when u fully charge the device.

Set at 1500. I'm at 85% with 3 hours run time, that's 1 hour deep sleep, 1 hour surfing n downloading updates plus podcast updates so a half hour of the download notification flashing and 1 hour reading an eBook. So total screen time 2 hours with 1 hour of WiFi running at max in that two hours. I find downloading stuff when surfing other stuff is my biggest battery draw. Happy so far.
[Nexus 7 Android Development] R3dbeaver:
after about a day with a30, everythin feels good. however...

it was completely out of battery last night. when i charge it, it would reboot a few times whenever it tried to boot. i had assume it was the Trickster delayed settings, so i disabled that and it was ok for a while.then it randomly rebooted twice more. then it would be fine.

in the morning, i checked it out, it was at 92% which is... very odd. since it would fully charged in a couple of hours or so. when i checked the battery settings, it says "charging (USB)" while connected to the wall! then i unplugged it, plug it back in, and then it says "charging (AC)". then all is well.

weird......

Is the TouchDemand Governor now supported by trickster mod? If I install the newest trickster mod, the selected governor is touchdemand. So that's right ? And we can tweak the governor control if we want?

The new parameters are missing from governor control. Use a file manager or setcpu for now ( don't use setcpu for anything else other than governor control)

[Nexus 7 Android Development] Metallice:
Pretty good light ROM, but at least some of their perceived "speed/smoothness" comes from cutting animation times in half or even smaller. Kind of sneaky IMO.

You can do the same with any ROM in developer settings... I like / highly recommend

Window - 0.5x

Transition - 1.0x

Animator - 0.5x

Speeds things up but leaves the nice recents windows shrinking/expanding animation intact and not looking jerky and ugly.

Just my impressions of a30 so far.

1. I LOVE the touchdemand governor! It makes the device very smooth and lag free.

2. Battery life seems to be much improved, I'll post my results when I finish this charge.

3. Not an impression, but this kernel is so awesome!

Thanks for your hard work, metallice. This is the best N7 kernel ever.

I agree this kernel at a30 is an absolute beast. I am 1000000% happy with my tablet.

I liked a28 but a30 is wonderful: very smooth, yet battery friendly!

I m just at the beginning of my second battery cycle but I felt it was consuming slightly more battery, so I just set sampling down factor to 1. Will see, but I'm already pretty happyand I feels it is in the sweet spot.

Concerning the other comments:

No reboot problems here, the screen brightness seem to behave better than before (changes are less radical), benchmark score are slightly higher (for what it worth).

Also, trickster mod settings are applied correctly after a reboot without requiring a delay.

Replying to my own message to note that two days ago Google finally acknowledged that the 4.2 bluetooth implementation was broken, and to announce that it was fixed in the latest update. Is that a kernel issue, or a ROM issue?

If your ROM supports it, the option to reboot to recovery or the boot loader will show in the power button long-press options popup someplace (depends on the ROM). Otherwise just hold power+vol_down to go to the bootloader, which it will do after it takes the screen shot (which is what that button combo does when the N7 is on). From there go to recovery.

IMHO paranoidandroid is the best rom for the nexus7. Runs great and supports the coolness of tablet interface. I think this is still the only rom that has it.

Testing out a new touchdemand parameter - touch_min_cores. Pretty obvious what it does. Duration is touch_floor_freq. Doesn't take effect if the touch event occurs while using the LP core. That way it doesn't kick in during very light loads and waste battery. May leave it disabled by default though.
