I've seen your eMMC commit, picked from Samsung.
<Rebellos>
What's this about?
<Entropy512>
Samsung fucked up their wear levellers again
<Rebellos>
Looks ominously similiar to I9100 tale.
<Entropy512>
GS3s were failing left and right at around the 200-250 day old mark
<Entropy512>
very similar symptoms
<Rebellos>
Oh, sweet. Maybe they should consider stopping to produce eMMCs then and use SanDisks? O.o
<Entropy512>
in some ways nastier due to no known trigger causes other than normal usage
<Rebellos>
Ah, "sudden death"
<Rebellos>
Any official comments from Sammy?
<Rebellos>
Or, actually ANY comments from them?
<Rebellos>
That's so silly, weren't that series of faulty SGS3 manufactured right when we were trying to fight SGS2 failure? O.o
<Entropy512>
yup
<Entropy512>
there was one of those semi-unofficial "we're working on it" comments
<Entropy512>
I was shocked we saw something this soon
<Entropy512>
just look at the "we're working diligently" claim in June...
<Rebellos>
When did they drop Update7?
<Entropy512>
tuesday I think
<Rebellos>
Sweet, I've got VTU00M 0xF1

I want to add a little bit so it prints out the date
<Entropy512>
I'm curious how many devices actually have the date the patch checks for
<Entropy512>
I wonder when ralekdev will handle my latest decompile request... I'm really curious to see if this FIMC1 shit is Gingerbread leftovers
<Rebellos>
0x20120413
<Rebellos>
Is this 2012/04/13, or something completely else?
<Rebellos>
Got manufacturing date 05/2012 here, so probably it's matching up.
<Entropy512>
Rebellos: I think that's it
<Rebellos>
So we got it locking up the same way as I9100's chip, but this time we don't know what's triggering it? Wonderful, I guess SGS4 is going to have bug that will make it hard brick in temperature bigger than 40C.

Rebellos: yup. As far as I can tell, my guess is some sort of integer overflow
<Entropy512>
or signed vs. unsigned
<Rebellos>
We should suggest them to put much NOPs in next eMMC ROMs, so there's place for patches.

or just be afraid any time you see a Samsung eMMC model ID
<Entropy512>
i am sad
<Entropy512>
Sony bought Samsung flash for Xperia T. :(
<Rebellos>
lolwhat?
<Rebellos>
Ah, you mean chip.
<Rebellos>
oknvm ;d
<Rebellos>
SanDisk ftw.
<Entropy512>
yeah or toshiba
<Entropy512>
fun fact: ODROID uses toshiba instead of samsung emmc

im trying to fix the noticable difference in touch input performance on battery and charging
<ankitkv>
on i9100g
<ankitkv>
ive had success as of now
<ankitkv>
but im doing some trial and error so as to make the minimum possible changes
stickyboy has quit [Quit: leaving]
<ankitkv>
ill be willing to spend time doing some reverse engineering that you mightve been lazy to do in the past if thats necessary. eg. i read about some issue with automatic brightness on xda
<codeworkx>
write a open sensor hal
<DooMMasteR>
I am still experiencing the flash crash bug on the i9300
<DooMMasteR>
is there any apparent fix for it?
<Espenfjo>
If there were, it would have been fixed already
<Entropy512>
thank Samsung for giving us hacked-up Gingerbread sources and pawning them off as "ICS" source
stickyboy has joined #teamhacksung
<Entropy512>
open sensor HAL shouldn't be too difficult on G if it has similar sensors to I9100 or N7000
<Entropy512>
would be a good project for a new person. :)
<DooMMasteR>
the cam works fine until the flash kicks in
<DooMMasteR>
from there on the camera cannot connect until I reboot the phone
<Entropy512>
yeah samsung's HALs do weird shit with flash
<Entropy512>
like on I9100/N7000/I777, the flash often triggers when exiting camera app
<Entropy512>
would be easy with an opensoruce CAM HAL
<Entropy512>
but
<Entropy512>
it's an undocumented blob from hell
<Espenfjo>
should probably be easy enough to fix in the wrapper as well.. But hey.. There are worse bugs
<DooMMasteR>
so no fix?
<DooMMasteR>
so… back to stock -.-
<a-st>
Hm. I wish I would be (more) into android development
<ankitkv>
open sensor hal, sounds like a fun project, ill give it a shot :)
<Entropy512>
yeah, use Z-device test to figure out which sensors you have
<Entropy512>
then look at I9100 and N7000 sensor HALs for hints
<Entropy512>
hopefully your sensors are similar
<ankitkv>
alright
<a-st>
Haha only superbrains around =) Incredible you do guys :)
<a-st>
+what ;)

hmm NFC is also not working :(
<DooMMasteR>
hmm with NFC and Camera not working… CM10.1 is pretty much not a daily driver atm -.-
<stickyboy>
...
<slick_rick>
DooMMasteR: you realize this is the dev channel right?
<slick_rick>
read the topic
<DooMMasteR>
yeah… but maybe someone could have had insight on the problem…

so, reversing the eMMC fix in the latest kernel shows that the eMMC controller is ARM :)
<Oranav>
it would be really nice to read its RAM and reverse the firmware to see what has changed
<Oranav>
and sorry for the off-topicness :)

Well, I've found some code to dump the eMMC controller RAM. Will diff this later, should be fun :)

Entropy512 thanks for that statement. I can sell this thing before it becomes note3 and un-sellable
<ankitkv>
ill get to it tomorrow, im almost done testing the touch on battery..
<ankitkv>
i have to leave for a seminar in 2 hours. its 3:40am, I just skipped sleeptime ._.

ankitkv welcome to my life :)

about what?
<Oranav>
I have some insights about the eMMC patch, and I think I know how to dump its RAM, but I can't post on XDA's developers discussion since I'm new there, and it's off-topic for this channel
<Oranav>
I saw that you wrote about it on XDA
<Oranav>
could be somewhat helpful to understand what's going on there
<Entropy512>
ah... maybe something for next week
<Entropy512>
i have family visiting tomorrow morning
humberos has quit [Quit: Ex-Chat]
<Oranav>
oh, I see. just wondered if you've done anything yourself yet. I'll dump its RAM and start an IDB tomorrow, it looks like ARM (Samsung's patch is THUMB code) and it's fun :)
