[DEV] Loadable Modules for Gingersense Incredible [Updated 9/18 - Support for OTA]

tiny4579 · Aug 13, 2011

HTC released gingerbread via OTA but they did not support additional modules. This thread has flashable zips for both the leaked kernel and the one from the "OTA".

Added flashable modules to attachments that are flashable in recovery.

I have created a zip of some of the more useful modules for our device:

Code:

cpufreq_conservative.ko
cpufreq_smartass.ko (thanks Chad for the help here)
ext4.ko
jbd2.ko (necessary for me to load ext4)
tun.ko
perflock_disable.ko (I actually compiled this one a little different but confirmed it would load and not get the exec format error)

Update: Smartass is working now with assistance from chad in resolving those errors. Decided to not worry about interactive for now.

Further information:

If you don't use the CWM flashable zip you will need to load perflock_disable a special way as it needs to be called with a special parameter to make it work correctly. Try adding below to a script. Credit to Calkulin for the script.

Code:

if [ -e /system/lib/modules/perflock_disable.ko ]; then
    insmod /system/lib/modules/perflock_disable.ko
    if [ $? -eq 0 ]; then
	echo "Perflock DISABLED"
    else
	addr=`awk '$3 == "perflock_notifier_call" { print "0x"$1; }' /proc/kallsyms`
	if [ -n "$addr" ]; then
	    insmod /system/lib/modules/perflock_disable.ko "perflock_notifier_call_addr=$addr"
	    if [ $? -eq 0 ]; then
	    	echo "Perflock DISABLED"
    	    else
	    	echo "ERROR!!! Perflock could NOT be DISABLED"
	    fi
	fi
    fi
fi

Conap (for BootManager and helping me test ext4 on an SD ROM)
XDA (for teaching me so much about Android)
HTC (for the kernel source)
Chad0989 (for assistance in getting smartass CPU governor working)
Coolbho3000 (perflock_disable)
Calkulin for the module load script
anyone else who inspired me (apologize if I forgot)

I have attached a zip file to this. If you are not a dev you can still use the modules here but some basic ADB/terminal knowledge would be needed. The modules are open for testing though.

Attached zip files and CWM-flashable zip files for both OTA and leak-based ROMs.

inc_modules.zip - Just the loadable modules.
inc_modules_ota.zip - just the loadable modules - OTA-based ROMS (August leak)
inc_modules_ota_091811.zip - just the loadable modules - OTA-based ROMS (actual OTA from September)
inc_modules_CWM_flashable.zip - flashable zip that will also autoload modules at boot.
inc_modules_ota_CWM_flashable.zip - flashable zip that will also autoload modules at boot - OTA-based ROMS (August leak)
inc_modules_ota_091811_CWM_flashable.zip - flashable zip that will also autoload modules at boot - OTA-based ROMS (Actual OTA from September)

I'm glad some one took this up I had been wondering the same thing since HTC opened the dev section. I had found another site that had a more extensive write up on how to build kernels but I'm not very fluent in linux and was a little intimidated at trying. At least I now know that it can be done. Maybe we can get Chad to try and port it over?

Awesome. A ray of hope.

Good job Tiny! I know someone was just asking for a tun.ko module and now I can't remember who it was. Hopefully they see your post.

Thanks!

I'm trying to add more existing modules but my compiler treats warnings as errors so it won't build. Chad, if you see this post, any advice here?

I actually got them to build but they won't load still. I will play around with it more.

This is awesome. I was hoping for a tun.ko module! Now, do I just grab these and drop then in system/lib/modules and they should just work? Or are there steps I need to take to make them work? (I am honestly only concerned with the tun.ko)

renzo.olivares · Aug 13, 2011

oh wow this is incredible great job tiny!!! and the reason you probably cant get those other governors to work is because htc released an uncomplete source

Just drop in the ones you want and run insmod /system/lib/modules/tun.ko for tun.ko. You will have to do it at boot each time or get the dev to write an init.d script to load it.

would i need to make one for every module?

Joel,

No, just one script should work. I believe Synergy ROM already has the init.d script for some of them. See 00cpufreq_modules in /system/etc/init.d

All,

Updated OP with latest zip file. If you have downloaded previously, redownload to get the latest.

would it be likes this?

The first line should be:

Code:

#!/system/bin/sh

and it needs to have execute permissions or it won't execute. Also make sure to save it in UNIX format. I would also add the smartass module as it is quite popular. To test type lsmod from adb or terminal after boot. Hope this helps.

eeh im not good with init.d scripts lol

renzo.olivares · Aug 13, 2011

ok i think i got it would it be like this?

Code:

#!/system/bin/sh

/system/bin/insmod /system/lib/modules/tun.ko

hightech316 · Aug 13, 2011

Every shell script should contain

#!/system/bin/sh

Code:

#!/system/bin/sh /system/bin/insmod /system/lib/modules/tun.ko

Exactly!

Then just make a line for each module.

EDIT: Though you could just write it like this:

Code:

#!/system/bin/sh

insmod /system/lib/modules/tun.ko

Though to be safe and to make sure you are running that particular insmod command you can leave it the way you have it.
