what is the different between your signed_ril.zip (946.88K) and the one from XDA update_signed_radio_RIL_HK.zip (3.11MB)?

That one is made specifically for OpenDesire and includes the files needed for OD that's build from AOSP. This one is based on that but only installs the files that are different for MCR. So this mod only works on MCR R8.

Same here :P Although i don't know if I should get lower than the 75-100 already in the script. It seems stable as it is.

when you apply the undervolt driver using the supplied zip (from xda) does it do the init script bit itself after flashing or is that something I need to do manually?

So if this RIL bit is so important, why were we all flashing radios so willy nilly during initial Desire development? Were we just chancing it that the existing RILs would work?

Preety much, yes :P

That's why Paul was relented to try out the new radio, he wanted the RIL's.

In other news: See post #3

CFQ Scheduler was added, Undervolt on it's way.

Undervolt and CFQ sched are being prepared.

* CFQ IO Sched attached. The archive is not signed as issues were reported with signed files. I can't test it here. Waiting for your feedback. Normally you should see

'CFQ scheduler support activated for /sys/block/mtdblock' in logs.

If you're familiar with Linux you may try:

cat /sys/block/mtdblock0/queue/scheduler

The result of the above command should contain 'cfq' text.

* Undervolt (http://forum.xda-developers.com/showpost.php?p=8023043&postcount=1)

Credits: XDA's FloHimself and iscaela for modules.

What is that CFQ thingy for? Do I have to flash both files if I want the undervolt?

using r8 + the power MOD + Calibrating my Desire Battery using the instructions from here I have much beter results today ...

My first day using this Mod - 12 hours in and I've got 75% battery left. Not as good as what others are reporting in this thread, but definitely better than it used to be... normally by this point i'd be below 50% at least.

I'm keen to try the calibration process linked above - has anyone else tried it and had noticeable improvement in battery life?

I restored back to before I applied the undervolt from xda, applied yours (applied from recovery) but I can see no evidence of CFQ in the log in aLogcat?

Is there a reason you only added CFQ support for the ROM and not also for the SD-Card? At least that's what the script is doing (deadline for the SD-Card, cfq for the ROM).

Edit:

Oh wait, the script isn't doing anything. I pushed the required stuff manually with adb rather than installing the zip. I also took care about the rights, correct users and groups etc. But somehow I can't get the cfq scheduler working.

# cat /sys/block/mtdblock0/queue/scheduler

cat /sys/block/mtdblock0/queue/scheduler

noop anticipatory [deadline]
Manual insmod: 
# insmod /system/lib/modules/cfq-iosched.ko

insmod /system/lib/modules/cfq-iosched.ko

insmod: can't insert '/system/lib/modules/cfq-iosched.ko': invalid module format

Edit2:

Somehow the module I pushed was either corrupted or not for my kernel (default MCR8 kernel). The size is the same as the module I already had on my PC but the hash was different. Pushed that module and cfq works now. But still the question is, why not to use cfq for the SD-Card as well?

Try this cfq-module. Push it via adb push cfq-iosched.ko /system/lib/modules in recovery mode after you have mounted the system partition.

hmmm, very strange I flashed it twice just in case, but the CFQ IO sheduler is missing and the module isnt loaded automagically ...

# cat /sys/block/mtdblock0/queue/scheduler

noop anticipatory [deadline]

# lsmod

bcm4329 202947 0 - Live 0xbf015000

cpufreq_powersave 668 1 - Live 0xbf012000

cpufreq_interactive 2368 0 - Live 0xbf00c000

undervolt 2644 0 - Live 0xbf006000

perflock_disable 752 0 - Live 0xbf000000

BUT .. the module and the init.d script are there :P

# ls system/lib/modules

bcm4329.ko cpufreq_interactive.ko perflock_disable3215.ko undervolt.ko

cfq-iosched.ko cpufreq_powersave.ko tun.ko

# ls -all /etc/init.d/98*

-rwxr-xr-x 1 0 2000 2137 Aug 1 2008 /etc/init.d/98mods01_screenstate_scaling

-rwxr-xr-x 1 0 0 856 Aug 1 2008 /etc/init.d/98mods02cfq-iosched

The problem is with the module version ...

If I load it manualy I have got:

insmod /system/lib/modules/cfq-iosched.ko

insmod: can't insert '/system/lib/modules/cfq-iosched.ko': invalid module format

dmesg

...

[ 679.698944] cfq_iosched: version magic '2.6.32.15-g6a358a9 preempt mod_unload ARMv7 ' should be '2.6.32.15-gf9c0527 preempt mod_unload ARMv7 '

In R8 the kernel version is not 2.6.32.15-g6a358a9, but 2.6.32.15-gf9c0527

Taken directly from Linux kernel:

"The CFQ I/O scheduler tries to distribute bandwidth equally │

│ among all processes in the system. It should provide a fair │

│ and low latency working environment, suitable for both desktop │

│ and server systems. │

│ │

│ This is the default I/O scheduler."

More info here:

http://kerneltrap.org/node/580

http://en.wikipedia.org/wiki/CFQ

No, there's no need to flash both.

How can I tell if CFQ is active? :)

Also when I ran:

ls -all /etc/init.d/

from within adb shell, it keeps telling me the directory doesn't exist? :P

what is the output of 'lsmod'?
