Re: kernel mod to enable USB fast charging

schweet. I just got done doing it for my kernel though I haven't tested it yet.

 

[sammyz]

Anyone test mine??? Btw jawz, I added patch to /arch/arm/mach-msm/lge and for the something_Herring.c I added to device_lge.c I think it's called.

Re: kernel mod to enable USB fast charging

source was too big for mediafire....made a bitbucket and added source here:
https://bitbucket.org/sammyz/iscream_thunderc-2.6.35-rebase/src/225449b192e7
I don't know how to add new branch so it is still test15 -____-
wanted to rename it test15_fastcharge.....oh well..

flashable zip download: http://www.mediafire.com/?mc9xgf18xa5nsas
someone test this please

Re: kernel mod to enable USB fast charging

i'm having trouble with yours rebooting my phone before I can test it.
for what it's worth this version of his patch seems to match up more with the content of the files on our phones considering it's for another msm7x27 & cdma model phone (he has 7 versions of the patch on separate threads on the xda forums but the one below is the only one I saw for our chipset).

[KERNEL PATCH] Force AC (fast) Charging - xda-developers

following this version of the patch I was modifying

/arch/arm/mach-msm/lge/Kconfig 
    +config FORCE_FAST_CHARGE 
 
/arch/arm/mach-msm/lge/Makefile 
    +obj-$(CONFIG_FORCE_FAST_CHARGE) 
 
/arch/arm/mach-msm/lge/fastchg.c 
    +#include <linux/fastchg.h> 
     
/drivers/usb/gadget/msm72k_udc.c 
    +#ifdef CONFIG_FORCE_FAST_CHARGE 
    +#include <linux/fastchg.h> 
     
/include/linux/fastchg.h

when I try to enable it on my version with the commands:

Fast charge can be toggled by issuing:
echo 1 > /sys/kernel/fast_charge/force_fast_charge

and off:
echo 0 > /sys/kernel/fast_charge/force_fast_charge

On mine I get "cannot create /sys/kernel/fast_charge/force_fast_charge: directory nonexistent"

Well, when in doubt I'm messaging the creator of the patch

 

[sammyz]

Well, I'm gonna try for my phone (MS690) when it works correctly I'll upload source and try to patch VM670 as well, or if you get VM670 patched correctly I'll patch MS690 the same way and give credit to you jawz, and the original guy who made the patch.

Re: kernel mod to enable USB fast charging

I believe I've got it working had to add #include <linux/module.h> to the fastchg.c file. download here to test.
I'm posting further instructions on the jawz101 kernel threads

 

[tvall]

Sweet! Can you upload a patch too? I'd love to try to use this on ics or jb

 

[sammyz]

Where's the source at for the working mod??? I wanna do this for some OM kernels

I get this error while building:

drivers/built-in.o: In function `usb_chg_detect':
lowmemorykiller.c:(.text+0x6f124): undefined reference to `force_fast_charge'
make: *** [.tmp_vmlinux1] Error 1

any idea?

and this is almost the end of the building process

 

[ThatGuyLurkin]

Im a bit lost. I flashed it a couple days ago, everything's still milky smooth on GingerDX. But, this patch, is always on? And does it only work via USB?
