If its not supported by the kernel, then its not running at 920MHz

If I benchmark it and it has similar results as the 768MHz, that means its not running at 920MHz

Even if it was running at 920MHz the battery life will go down super fast

To have it running at 920MHz, that speed must be added to the kernel itself.

this goes to whoever is interested in a working tun module (needed by vpnc and several other apps): the attached file is recompiled for disc0 kernel, you can now insmod it.

the previous errors were caused by CONFIG_LOCALVERSION in .config, that was set to -b02 instead of -b01, fyi.

edit: for some reason liquid crashes and reboots when vpnc tries to connect, don't know if is tun.ko-related. will investigate..

tun.ko.zip

Okey, good. You can also drop voltage on 245000 to 900mV. This will increase battery life when phone's screen is off or when phone is idle. I will continue testing tomorrow to find the optimal values.

BTW. Have you noticed the msm_i2c warnings in dmesg? I don't have the log right now, but it's something like: "Warning bus was busy". I googled this and noticed that cyanogen also had this in one of his CM's, but I couldn't find the reason or solution for it :D

Yes I did, and I think that acer just "shut up" does errors not to show in release version ! :\

Well, this week I think I would not be so active around here because I have exams :\ ..

@liquid_it

Thanks alot! I'm glad somebody could compile a working module! :D

Atleast it insmods... Before it just crashed my phone. I'll test it ASAP.

That's too bad about vpnc, but no rush guys, if you get it fixed, that's awesome, if not, thanks anyways guys!

Maybe OpenVPN will work with this tun.ko!

UPDATE: It insmods, and is listed under lsmod!!!! Yay! I'm testing OpenVPN now, so far so good.

UPDATE2: After successful insmod /sdcard/download/tun.ko and I launch OpenVPN (I doubled checked the openvpn binaries), when it tries to authenticate, it reboots the phone. :D Too bad, but still awesome.

UPDATE3: Trying another OpenVPN GUI/client, seems to be working... EDIT: Nope, restarts too, when authenticating. It must be a problem with the module.

While disc0 is busy with school, here's the 920mhz image. It has 128-245-384-567-768-920 frequencies. I didn't want to put other frequencies because too many scaling steps decrease performance. All credit go to disc0 for his original kernel work! Give him a beer :D

Remember, I take no responsibility of this boot image.

great, i'm downloadig :lol::D:D

i will give feedback in some minutes :D

EDIT:

all works fine :D very fast B):D thanks very muuuuuuuuuuuuuuuuuch :(

tips:

if you want to use setcpu you must

create setcpu.txt to the root of your sd card and put this in it

128000,245000,384000,576000,768000,920000,998400

On the device selection list in setcpu, select the last option.

like this you can see the 128mhz option :D and for 990mhz just put max on 998mhz :lol:

Works fine on my Liquid (the 1Ghz one was not stable) after a few tests (need more to be sure but it's definitly a good start). Btw on my settings the CPU speed is 768 but I guess it's just a constant read somewhere on the kernel code.

Good to hear it works. I would like to know if there are any problems with sleep mode -> wake, because it's using 128MHz for that.

BTW. The 920MHz is precisely 921600. You might need to set it like that for SetCPU.

Where do you read the cpu speed? If you have adb shell you can see it by;

# cat /sys/devices/system/cpu/cpu0/cpufreq/stats/time_in_state = How much each speed is used in milliseconds.

# cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_cur_freq = Your current cpu speed

I was talking about what we can read in Settings/About/Informations :D

Doing the time_in_state, I have :

128000 126121

245000 2559

384000 2583

576000 3261

768000 2247

921600 30118

So far so good :lol:

And for now I d'ont have any problem with standby mode :D

no problem from sleep mode :D all is fantastic (before to 1ghz my liquid freeze an reboot all time) :D

thanks for the correct value :lol: 921600

Now I understand why Acer limited the speed so low.

My Liquid is rebooting with BLC's 920 boot img. I just opened the browser and it crashed immediately. With Disc0's 998 I had a constant boot loop.

one crash for 24hours, it seems to be okay :D

it crashed when i wanted to make a call... may be the battery voltage got drained to much

EDIT: HOLY s***, phone freezed and doesnt boot anymore -.-

>> restoring to 768 Mhz

my phone did reboot once but it seemed more like a bug related to the usb connection between the phone and pc it happened exactly in the moment i connected the phone to the pc

we'll see in the future
