[Kernel] Ziggy471 MECHA BETA Kernel UPDATED 3 May 11

3 May 11

This is a big change, it's something I had been thinking about for awhile, and some of you mentioned taking out frequencies, so instead of making the choice of which frequencies to get rid of for everyone, I decided to proceed with my previous plans. This is just a sysfs implementation, there is no GUI for it, I made a promise to myself many years ago to never program Java again if I didn't have to, so I'll leave a GUI to someone else.

Change log:
Added the ability to selectively enable/disable frequencies (See Post #2 for usage)
Opened up ALL frequencies in the table
WARNING: 24576 and 61440 can cause issues with ADB loosing connection.

I reverted back to the bad source tree, fixed the issue with the proximity sensor, just 1 line of code in the IRQ power management, better than how I had worked around it prior. I'm not seeing the run away processor that had arose in the last builds. Sorry for the long time between builds, I was without the TB for 2 days, if your data goes out, call VZW, don't assume it's your phone and re-activate your INC. lol

Change log:
Reverted source tree, applied all the patches again
Lowered the proximity sensor voltage by .5V, still more room on that

Alright, been a little busy today, ok, not really that bad, it's just a long list. Since I finally got that prox sensor issue taken care of, I went ahead and decided to get everything else back in. I'm getting it closer to a merge with Frankenstine, should happen in a few weeks hopefully.

25 Apr 11 Changelog:
2.6.32.39 for all
Fixed the issue with SpareParts FCing, my version number was to long
Implement backported 2.6.38 Automatic process group scheduling patch
Implement BFS 401 and backported ck3 patchset from 2.6.38
[CPUFREQ] ondemand: Refactor frequency increase code
[CPUFREQ] ondemand: Fix ondemand to not request targets outside policy limits
[CPUFREQ] ondemand: add sampling_down_factor tunable to improve ondemand performance
[CPUFREQ] ondemand: Add filter for input events
[CPUFREQ] ondemand: Featurize the input event handler
[CPUFREQ] ondemand: Set sampling_down_factor to 50
[CPUFREQ] interactive: fix crash on CPU shutdown
Optimized ARM RWSEM algorithm
Enabled HW3D

I have 2 kernels for you guys to play with tonight.

1. 2.6.32.21, I was finally able to find and at least work around for now, the issue with the proximity sensor. Once I figured that out, I was able to continue to patch it closer to mainline, in that are a lot of other 'tweaks' some are doing.

2. 2.6.32.39, Since I was able to patch the kernel closer to mainline, I was able to patch up to 2.6.32.39 much easier, only 1 fail, and a couple of fuzz's. This seems to be the smoothest of the two, at lest in my opinion.

What I need from you guys is what is working and not working. Also, those that may have random reboots, just up the minimum frequency one step, some phones aren't working so good at 122MHz. I also increased the voltage on both kernels by +50mV at all levels.

Nothing to special in this kernel, just some of the usual patches. You should see a good battery life and performance. The frequency table is a lot smaller than I had in previous versions out there, and I've capped it at 1728 MHz, to many issues above that right now. The original max frequency of the 'Bolt was 1024 MHz, not really, 19200 * 53 != 1024000, however, since I don't have that in the table, the new default is 1036.8 MHz. From 806.4 MHz up to 1728 MHz, the table progresses in multiples of 76.8 MHz.

So here's the table:
122.88 MHz (850 mV)
184.32 MHz (850 mV)
192.00 MHz (850 mV)
245.76 MHz (850 mV)
368.64 MHz (875 mV)
768.00 MHz (900 mV)
883.20 MHz (1000 mV)
960.00 MHz (1025 mV)
1036.8 MHz (1050 mV) Default Max
1113.6 MHz (1075 mV)
1190.4 MHz (1100 mV)
1267.2 MHz (1125 mV)
1344.0 MHz (1150 mV)
1420.8 MHz (1225 mV)
1497.6 MHz (1250 mV)
1574.4 MHz (1350 mV)
1651.2 MHz (1350 mV)
1728.0 MHz (1350 mV)


Change log so far:

2.6.32.21 (Yeah I know, had to start over from scratch)
CIFS, EXT4, TUN built in
Kernel LZMA support
Conservative Governor 50K sampling
Interactive Governor
Smartass Governor with working sysfs interface (default)
AIC3254 tweaks (Shuts off the audio chip to save power)
Updated acpuclock-7x30.c as close to Aurora Forums as possible
VDD sysfs interface
Lower Wi-Fi voltage
OverClock/UnderVolt
Turned off almost all Debug and Tracing (That was a pain, HTC doesn't understand that not everyone wants debug on)
Default range - 122.88 MHz - 1036.8 MHz
Capable range - 122.88 MHz - 1728.0 MHz


If you would like to change the voltages, or use sysfs for what it's intended, I have a nice write-up on my site here. I explain in almost to much detail how to use the sysfs inerface to control the voltage levels, the frequency table, etc.


Performance:
Linpack:
1036.8 MHz - 40.131
1728.0 MHz - 59.288
Quad:
1036.8 MHz - 2407
1728.0 MHz - 3056

NOTE: It is not possible to disable the policy min or max.

To see the current state of the frequency table:

To disable ALL frequencies outside of the current policy minimum and maximum:
echo 1 > /sys/devices/system/cpu/cpu0/cpufreq/user_freqs
To restore the kernel defaults:

Re: [Kernel] Ziggy471 MECHA BETA Kernel 22 Apr 11

Damn glad to find you here, thanks to the link in the Virus rom thread.
Loaded up the kernel last night and played around on the phone for about an hour and had absolutely no hickups. It sat with no data connection all night and only lost a few %'s of battery. I'll let you know if I run into anything today.

Thanks!!

Re: [Kernel] Ziggy471 MECHA BETA Kernel 22 Apr 11

Hey there old buddy. Great to see you around these parts again.
I had seen you were active with Thunderbolt in hand, when I saw your GPS lock time fix over at XDA.
Glad to see you are working on other projects as well.
I may have to try out some of these kernels as you release them.

Anyhow, mostly just wanted to say hey and thanks for your efforts, as always. Hope things are well for you and I may hit you up on Messenger again here soon if I catch you on there. It's been a while.

That GPS mod was something I found back when I had the Incredible, someone just posted it after I mentioned it in IRC one night.

Yeah, I've missed chatting with you on MSN, I see you sign in every now and then, but I'm always in the middle of something, and forget to start a chat.

There will be more kernels coming soon, most likely another one tonight. I'm slowly starting to move towards mainline, and so far the prox sensor is still working, so I think I'll release another one to the wild.

Most likely it's a voltage issue, I dropped the voltages considerably from stock. They work fine on my phone and imneveral0n's, however that's not everyone's. I also don't overclock much at all, just every now and then for benchmarks, then I revert back to the stock settings in the kernel.

I'll go ahead and up the voltage table a little higher tomorrow morning to see if that helps you, but in the mean time, you can adjust the voltages up by yourself, I'd recommend around +50mV to start with. There's a link in the first post to my site where I explain in great detail how to do that.

Has run really good for me today. One strange thing....my flash light came on and wouldn't turn off until i rebooted. Ran GPS for a good 20 minutes going in and out of 4g and it stayed great. Pretty normal use other than that. No reboots.
Thanks Ziggy!
