Benchmark Results

If you've been following the different hacks/fixes over in the Dev section you'll know there's quite a bit of debate as to the validity of the benchmark results obtained, specifically in Quadrant.
To lay it out a little I've posted results for 3 different benchmark programs in 3 different situations.
Below are my results for the stock kernel + app lag fix, AJerman's Overclock Kernel, and Nukacola's Ext3/sdcard fix.

[KERNEL] Undervolt driver for the stock HTC kernel for Desire and others (2.6.32.15)

This kernel module allows you to run any official Froyo kernel image from HTC with reduced CPU voltages at each frequency. Reducing voltage decreases the power consumed by the CPU (dissipated as heat).
INSTALL:
You need root or an unrestricted recovery image (e.g ClockworkMod) to install this. The default settings decrease voltage by 75-100 mV which seems stable on my device. Just download the attached file and select it from recovery or ROM Manager.
I've built "update.zip" files for the Desire with Linux kernel versions 2.6.32.15-gf9c0527, 2.6.32.15-gd96f2c0, and 2.6.32.15-g6a358a9. You can check your kernel version in Settings->About phone->Software information.
Other HTC devices running Froyo are supported. If you have a different device, please give me the full version number and I can add an update.zip for it.
Undervolt driver for the EVO 4G
Added undervolt-2.6.32.15-gd96f2c0-20100907.zip.
Added undervolt-2.6.32.15-g6a358a9-20100907.zip.
Added undervolt-2.6.32.15-gf5a401c-20100907.zip.
USAGE:
Read the instructions above first. If you are happy with the default settings, you don't need to read this unless you're curious
To load the driver, use an init script like this one (included):
Code:
#!/system/bin/sh
#
# Load undervolt for htc-kernel
addr=`awk '$3 == "acpuclk_set_rate" { print "0x"$1; }' /proc/kallsyms`
if [ -n "$addr" ]; then
insmod /system/lib/modules/undervolt.ko "acpuclk_set_rate_addr=$addr"
if [ $? -eq 0 ]; then
echo '-75' > /proc/undervolt
echo '1225 1125' > /proc/undervolt
echo '1250 1150' > /proc/undervolt
echo '1275 1175' > /proc/undervolt
echo '1300 1200' > /proc/undervolt
echo '1' > /proc/undervolt
echo "+++ undervolt enabled"
exit 0
fi
fi
echo "+++ undervolt could not be enabled
The driver adds a "/proc/undervolt" knob to make voltage changes, reading from it prints the current default and adjusted voltages in mV for every CPU frequency, e.g.:
Code:
cat /proc/undervolt
1050 975 19200
1050 975 128000
...
1300 1200 960000
1300 1200 998400
Write a space-separated pair of default and adjusted voltages in mV to change the values in the table, e.g. to undervolt stock freqs using 1500 mV to 1000mV):
Code:
echo '1050 1000' > /proc/undervolt
.
Write '+' or '-' followed by a single number to adjust *all* voltages by that amount in mV:
Code:
echo '-25' > /proc/undervolt
The changes are NOT applied until you write the number 1:
Code:
echo '1' > /proc/undervolt
Writing the number 0 reverts all voltages to the default. This also happens when you unload the module with rmmod.
BACKGROUND:
I figured it would be possible to locate and modify acpu_freq_tbl on the stock HTC kernel with a LKM (since /dev/kmem isn't available), and I was right, although it involved peeking at the ARM opcodes. The method should also work for other HTC kernel images on recent devices (anything with a "Scorpion" CPU): Nexus One, Droid Incredible, EVO 4G. Overclocking will be possible with a bit more work.
This also disables the voltage constraints set by the board-specific configuration (e.g. in board-bravo.c or board-incrediblec.c). This was done by y patching the regulator_set_voltage function to simply ignore the constraints. The remaining limits are imposed by the driver for the regulator IC. The TPS65023 driver defines these for VDCDC1: min_uV = 800000, max_uV = 1600000.
KNOWN BUGS:
There is a vdd_undervolt parameter to set the default undervolt, but it is ignored (by insmod?), use +/- instead.

Very nice work!

That is, in fact, fantastic work
Of course it will be obsoleted when HTC decides to release their source but you know that
I assume you verified these actually work?

ok...this is nice i think!
i don't know much about kernel so...can i use the update.zip to install this kernel in my actual sense rom ?
just, install this and that's it? it starts working undervolted?

Did you account for the fact the stock kernel has board files to constrain the minimum
and maximum voltage?
eg, board-bravo.c:
.min_uV = 1000000
.max_uV = 1300000
The same goes for overclocking, the upper limit for the clock is set, hardcoded,
so you would need to change that as well.

sounds interesting!! I`ll try it very soon.

Yikes, I didn't know about that, is that in bravo_fixup (which I hope is in the .init section like acpu_freq_tbl_fixup)? Is board-bravo.c in the incrediblec or vanilla Android kernel trees? I'm using the supersonic source atm.
Thanks!

Thanks, I haven't hacked on the Linux kernel in ages and wasted a lot of time targeting acpu_freq_tbl_fixup originally (as you might have noticed in the comments).
The idea is that this should work with the stock kernel images of multiple devices without reflashing, and in future releases with only minor changes.
I didn't take a multimeter to the board, if that's what you mean... but acpu_freq_tbl is canonical list of voltages (unless something in board-bravo.c rewrites it after initialisation, which seems unlikely) and this is able to read and write to the table. The actual CPU frequencies are duplicated in another structure (which is why I haven't tried overclocking yet) but the voltages are read directly from the table and scaled to microvolts for the governor.

Thanks alot for your work. Does anybody have ' proof ' this script works on a Desire running standard HTC Froyo ?
There is no way to check is there, except having better battery life?
What kind of energy saving is possible with this method?
Thanks

Seems to work....but not below 1000mV, so like you say, isn't there ways to check it....

Ne0, you are on the Dutch television as we speak (the matrix revolutions)
At what mV is the desire standard doing ? Going to flash you 7.6 now

Thanks for the advice, folks. I've confirmed that the voltage changes are pushed to the regulator (the previous version had trouble applying table changes sometimes, but the regulator code would print a message when you exceeded the board configuration voltage constraints).
Are there other kernel versions or devices people want me to support? It's mostly a matter of changing the vermagic string in the file at this point.

thanks, installed on R8 Paul's (Modaco) ROM kernel 2.6.32.15-gf9c0527
it's working!

So how low can you go until you have problems? Is it safe to go bellow maxV=1000?

ANY value on ANY freq below 1000mV freezes device so, min value still being 1000mV
If you put any value below 1000 in init script, at my case, device freezes when load with -1.

This driver allows you to run any stock Froyo HTC Linux kernel with lowered CPU voltages. It modifies the voltage table at runtime.
I've built update.zip files for the Desire 2.6.32.15-gf9c0527 and 2.6.32.15-gd96f2c0 that applies a 75-100 mV undervolt which seems stable for me. Just download and install the files in recovery.

What can we expect from that modification ?
A lower heat of the processor (not sure regarding the difference) and a longer battery life ?
If I read that correctly, looks as a very interesting stuff.
(might be a stupid question, if so apologize)
Thank you.

is it usable on cm 6.0 stable?
anybody tried that?

Confirmed, don't go with any kernel below 1000mV without freeze.

can anyone explain how to install and to enable it? just run the update.zip and that's it???
can you feel different battery usage?

Needing developers for ZTE V875

Hi
I'm writing this because there is no tool for root and none custom rom available for this device. According to ZTE this phone is sold in China, Portugal and Brazil but there is no development for this phone. Here in Portugal we decided (in a portugues forum) to raise money to buy a new phone and pay shipping but we need developers to develop a tool for root and a custom rom.
Those interested, please send me a private message.
And any suggestion, please feel free to comment.

Ok, I know I'm crossing the line here, but I believe this can be crucial to the Development of this terminal. This is one of the stock rom's for this phone, and inside it's the default recovery.img. Maybe that will help you to start the development!
Here is the Stock Rom.
Good luck!

RomJOB 2
I did a custom rom for this device.
It is 2.3.5, rooted, zipalign, odexed, tweaks build.prop and int.d, battery percentage, bloatware removed and others.
You need to be rooted and have cwm on it.
Do a factory reset in cwm and install the zip.

1. Push with ADB the attached file tou your device. (if you don't know how to do this, let me know)
2. Then you need to be rooted. (it's another step)
3. Install ROM Manager or Quick Boot from the Playstore
4. Reboot into recovery through one of those apps
And that's it! You'll be booting into CWM 5.0.2.5 (I think it's this version)

Thank you. For right now, I don't have time at all since I'm moving home. But I will let you know as soon as I have the time, end of March beginnning April. I will PM you

[Q] Safe Voltages for SGS3

I just got the KT747 kernel on CM10 stable. I might want to under volt because battery life is sucky for some reason . I want to know how I can get the best battery life of this phone with this kernel. Any suggestions?

Depends on which cpu pvs you have. There is slow/nominal/fast, fast needs a lot less voltage where slow needs a lot more and thats where the stock kernel voltages default to (slow). Im running these voltages fine and just havent dropped em anymore cause I keep forgetting to, but i plan on dropping much more if I can....
Code:
clock - mv
1512 - 1130
1458 - 1115
1404 - 1115
1350 - 1105
1296 - 1105
1242 - 1080
1188 - 1075
1134 - 1060
1080 - 1055
1026 - 1005
972 - 1000
918 - 980
864 - 980
810 - 945
756 - 945
702 - 900
648 - 895
594 - 875
540 - 870
486 - 850
384 - 820
192 - 810
144 - 800
96 - 775
Keep in mind I have a fast pvs cpu so depending on what you have these may be to low for you.
Per Imoseyon's which would carry over to ktoonsez kernel fine....

The only way I know to check which cpu you have is to flash leankernel and from a terminal do "dmesg | grep ACPU"

When I do dmesg | grep ACPU in terminal emulator it says " Operation not permitted"
EDIT: I tried doing in I superuser mode and it gave nothing. Screenshots are below.

Says that its nominal

don't understand the recommended voltages
I see the recommended voltages set by imoseyon but when I only go into SETCPU and go the voltages tab I can only set ONE voltage for each line not a range like in imoseyon's post. Do I set that that one line to the max or min? PLEASE HELP THIS NOOB!
384000,900000 -----------------> This is what I mean. I can click on this line but it only allows me to set it to one number (not a range).

Those arent ranges those are cpu speed and voltages. i.e. 1900000,1300000 is 1.9ghz @ 1300mv

Thanks!
