sound tweaks

thanks for your plans to include the Tab into your work. Really appreciated.

Just to ask (I am not sure if this is the right time to ask) if you can include some good sound system (Viper, Wolfson, etc).

Thanks in advance.

Just walked in the door after 2 days of international flights (jet lag big time), please give me some time.

I'm not sure if you realize, but I am the builder of previous SkyHigh kernels for Tab S KitKat, just haven't the time to build for LL until now

Intend to have most features from older SkyHigh KK builds. BTW, Viper is not a kernel feature ..........

But one step at a time

Good stuff been waiting for this. Sky high was always one of the better stable kernels.
Just one request though. Could you build an F2FS compatible one aswell or at least release your source code on your repo so I can build it myself.

I might take a look at some point. I have never tested it, but a 800/805 user did say had it working on KK with SkyHigh + recovery ..........

I just spent 2 hours trying to sort out a compile error, if only I'd checked the GPU code. It has changed in LL and now uses midgard sources :cyclops: Just tired and not thinking straight and cherry-picking without actually looking !!. Continue tomorrow

I read that and he was actually wrong. I could see how he thought it had worked, but the script he used would never have worked on any of our roms, it actually did nothing.
All that happened was that the partition that he formatted to f2fs automatically got formatted back to ext 4 upon first boot.
Your kernel didn't work with an f2fs partition as it needed some modifications to the actual source code to make it work.
It was the same story with iron kernel, but Tkkg managed to get it to work by pulling in some changes from Nvertigo's repo.
I managed to get it to boot after making the required modifications to the ramdisk.
Unfortunately the kernel had other issues which caused the tablet to freeze. This was seemingly caused by adding hotplugging to the kernel.
I was then looking for a good t805 lollipop source to build from until iron kernel was fixed.
Unfortunately your repo didn't have the lollipop kernel source, so just left it alone until I could be bothered again.

For touchwiz LP and CM12.1?

Great news!

Good to be able to OC LP Rom.

Only TW.

Firstly, no disrespect to those Devs, I just find CM boring visually and tacky. It's just my personal opinion, not a criticism of one's choice to build or use

There is no "right" or "wrong". Secondly, I don't have time for it other than what I can/want to spare.

Editing OP.

Delete...... Good to see Skyhigh back! Was great in KitKat! Can't wait to see what's in for lollipop

Maybe you could assist with constructive help/feedback if/when the time comes.

Hi, upintheair, glad to see you come back! a few days ago, I compiled a custom LL kernel, using your gpu hooks. LL kernel uses a different graphic driver, but the code are more or less the same, just modify the corresponding files in midgard then gpu hooks are going to work.! I planned to share my kernel source on github but now you are going to develop a more advanced one, it seems that I can stop doing this and wait for your kernel, once it was out, I will flash it to replace my own.

I woke up early this morning, (body is still in another time zone), and have Synapse up and running.

Have already implemented: CPU voltage control, GPU OC/UC, GPU voltage control, GPU clock & governor control for new sources (not yet committed to github). Could give screen shot, but busy testing before Son goes to school

Just have an issue to sort out (not sure if ROM or kernel yet) for some apps FC on boot. Might be to do with Selinux

cbb77 · Nov 28, 2010 483 133 Massachusetts

Welcome back!! I am glad to see you making kernel for LL. I chose to stay on KitKat as I am getting way too good battery life from your kernel to switch. No lie, I get about a weeks worth of use before I have to charge it. Granted I am not a heavy use, average about 6 - 8 hours of total screen time, but it is truly a join to not have to charge each night. Previously the best I got was a day and half with the same use patterns. Again, welcome back and look forward to your LL kernel. This will now motivate me to upgrade. :good:

UpInTheAir · Jun 12, 2015

~~I'll probably release v1.0 for T700 & T705 today. Still a bit of work to do yet with Synapse.~~

T800 & T805 will be a while away yet as first beta reported failed to boot using same source. So I will build for my device first until I'm happy with it's progress, then take a look at 10.5" again.

EDIT: Changed my mind, I wish to continue instead of release. I don't want to hurry. Why stop when I'm on a roll
