[Kernel] - AwesomeSauce[2wcr][usb host]

[thicklizard]

This is just a little appetizer for everyone to hold them over while the great kernel chefs do their thing. this is my first attempt at a kernel. I am only posting this at themikmik.com. This is based on the 2.13 ota
Thanks to ca1ne for answering all my questions

Changelog 10/29/12
added sweep2wake
added ARM topology


Changelog 10/17/12
Added new asswax governor (thanks Zarboz)
optimized the crc32 algorithm (slice by 8 bytes)

Changelog 10/4/12
Usb host is working
enabled ntfs support
tweaked voltages(would love to hear feedback from the community on whether they need lowered)
enabled ksm


Changelog10/2/12
GPU OC or UC (Stock by default) to enable

I use script manager to create a script to run on boot, each time you reboot the values will revert back to default.

To increase maximum GPU frequency in 3D mode to 484 MHz:
echo 484000000 > /sys/devices/platform/kgsl-3d0.0/kgsl/kgsl-3d0/max_gpuclk

To increase maximum GPU frequency in 2D mode to 300 MHz:
echo 300000000 > /sys/devices/platform/kgsl-2d0.0/kgsl/kgsl-2d0/max_gpuclk
echo 300000000 > /sys/devices/platform/kgsl-2d1.1/kgsl/kgsl-2d1/max_gpuclk

Available frequencies:
3D: 484000000, 300000000, 266667000, 228571000, 200000000, 177778000, 27000000
2D: 300000000, 228571000, 200000000, 160000000, 96000000, 27000000

Lowmemory tweaks
Better tweak mpdecision for sense
tweak scheduling
here is a little explanation of kernel based thermal and mpdecision control

What is msm_thermal?

Kernel based 3-phase thermal control!
This replaces your /system/bin/thermald binary which is renamed by the installer to thermald_backup.

Check /sys/kernel/msm_thermal/conf/ for the thermal configuration

allowed_max_high = highest threshold (phase 3)
allowed_max_low = remove the throttling if we cooled down to this (clr_thrshold)
allowed_max_freq = max frequency if throttled (limit)

[...]mid[...] = same as above, just for phase 2
[...]low[...] = Lowest threshold (phase 1)

check_interval_ms = how often shall we check? (sampling rate)
Default: 1000ms (=1sec)

If you want to see msm_thermal doing it's job:
Code:

adb shell cat /proc/kmsg | grep 'msm_thermal'

What is msm_mpdecision?

100% kernel based multi core decision! (should cpu1 be online or not?)
This replaces your /system/bin/mpdecision binary which is renamed by the installer to mpdecision_backup.

Check /sys/kernel/msm_mpdecision/conf/ for the configuration.

startdelay = time until mpdecision starts doing it's magic (70000)
delay = time between checks (500)
pause = if something else plugs in the cpu, fall asleep for 10000
scroff_single_core = if the screen is off, don't plug in cpu1 (1)
nwns_threshold_up = runqueue threshold, if this is reached cpu1 will be hotplugged (35)
nwns_threshold_down = runqueue threshold, if this is reached cpu1 will be unplugged (5)
twts_threshold_up = time threshold, this amount of time must have passed (250)
twts_threshold_down = same as above (250)
enabled = enable(1) or disable(0) mpdecision. This does not affect scroff_single_core!
idle_freq = a value against that will be checked if a core +/- is requested. (486000)
If cpu0 is below that value and a core up of cpu1 is requested, nothing will happen.
If cpu1 is above that value and a core down of cpu1 is requested, nothing will happen. (otherwise it would now put down cpu1 even though it is still working)

(all times are in ms)

Changelog 10/1/12
with htcs new source they where many changes in code, so I will need to no if usb host still works as well as 2wcr.
For this release i implemented kernel based thermal control as well as kernel based mpdecision. these can be easily tweaked and modified by the end user. When installing I have a script change your rom based mpdecision and thermal files to a backup. this is meant to control cpu 1. on the old base cpu 1 did its own thing now we control it if you want to benchmark simply disable mpdecision, then when your done reapply it really easy. I also added a few new governors. This will boot and stay at stock speeds until changed by the user.

battery friendly mpdecision(to disable navigate to sys/kernel/msm_mpdecision/conf/enabled change the value to 0)


doing this can harm your phone I do not recomend but to each his own
to change the low value for thermal navigate to sys/kernel/thermal/allowed_low_freq and change to desired frequency

I will also be utilizing the son kernel updater zip.(flash like a normal zip)

Edit here is a flashable boot.img for those have issues flashing the regular zimage. If the ROM dev didn't make the boot img unsecured then the regular zimage flash won't work. I've also attached a flashable zip for my modules to go with the boot img. The modules are different than stock because they have been compiles with linaro if you fastboot the boot.img please flash this zip afterwards.

Thanks man. Always nice to have options .

[thetunicakid]

Thanks guy! Will give it a flash in few on 1.22 and post how it went vs stock if you could answer one thing? Or anyone can answer cause i honestly dunno? I read bout you helping everyone out with chads trial release and was alot talk about boot img and stuff. I also saw where for mean rom you done something lil different because of his extra tweaks he uses. I swapped and been on mikey's rom after running chaos all week. Do i simply wipe cache/dalv and flash or no? If there is alot effort i got no probs with 1.13. Thanks again for kernel!

Yep wipe dalvik and flash. The only issue people may have is if they have if they are on the stock rooted rom is the boot img is secured so they would need to flash a modded one first, but I can help with that. If you are on a custom Rom should be no problem.

Can't wait to try it. Don't suppose you have one I can flash in fastboot? Twrp just won't flash any kernels for me. I have to fastboot them.

What files do you need to fastboot them? If just the zimage and modules you could just take them out of the zip

I just flashed or attempted to flash?? Hmmm...im soff and flashed a 1000 kernels prolly but im not sure it took. Anybody know what this kernel lists as in your settings last page?

That looks just like a stock kernel listing to me? Most ive ever used had the name listed.
