[KERNEL] Sub501 Kernel, mods and control apk

[Guest snapilica]

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.

Thanks mate!

[Guest Paul]

Added the RIL bits to r9, thanks sub501.

[Guest zombiefly]

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?

[Guest Thomas1107]

Omg.. This is the best mod ever, made my battery last soooooo much longer.. my desire couldnt last a day before i used this mod!!! THANK YOU!!

[Guest spammyspam]

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.

[Guest Vulpix]

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)

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

[Guest Streetdaddy]

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?

is this different to the orig undervolt from xda?

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?

[Guest System of a pWne!^]

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?

i see the same results as you after installing the zips via recovery :P

[Guest System of a pWne!^]

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.

[Guest Endrus]

Should I omit using setCPU with this mod?

Is this mod doing anything better than setCPU?

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

The problem is with the module version ...

If I load it manualy I have got:

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

dmesg

...

Fixed kernel version issue. Please re-download and let me know if is working.

[Guest Sub501]

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

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.

[Guest Sub501]

The kernel module is the one from XDA (see credits).

The init.d script was a little bit modified.

[Guest Sub501]

Hi there,

CFQ, Undervolt and CIFS modules are available in post #3 ( http://android.modaco.com/index.php?s=&amp...t&p=1393130 )

Please let me know if there are working.

Cheers

i applied the new cfq file, however there is still no reference to CFQ in the log

[Guest Mekerz]

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
