and no I don't have a Z yet

CAF = CodeAurora Forum?
<IbrahimA>
yeah
<IbrahimA>
is CAF part of qualcomm?
<angelsl>
i feel like disassembling libsecion and writing it in C
<angelsl>
it's only 5kb, can't be that hard..

IbrahimA: I don't know if it's part of qualcomm, but it's tightly connected
<Entropy512>
far more than Insignal is with Samsung
<IbrahimA>
ah
<Entropy512>
angelsl: might be able to get an idea of what it's doing by looking at manta libion
<Entropy512>
and look at kernel differences in the ion interface between 4412 kernel and qcom kernels
<Entropy512>
i wonder if manta libion would work on exynos4
<angelsl>
Entropy512: it looks nearly identical
<angelsl>
i'm looking at 4412 libsecion.so in IDA
<angelsl>
compared to manta libion
<angelsl>
only a few exports not present in manta
<angelsl>
yup
<angelsl>
i only need to write createIONMem, destroyIONMem, ion_msync and ion_getphys
<angelsl>
this is shockingly simple actually
<Entropy512>
hmm that was interesting
<Entropy512>
my last round of "try to get miracast working" hacks led to a hard lockup of my n8013
<Entropy512>
i have the most unholy pile of hacks in here at this point though...

hi MacDrunk
<angelsl>
i'm disassembling libsecion.so for 4412 in IDA

ah
<w00tc0d3>
you can reaqd ARM ASM?

<w00tc0d3>
angelsl: wish I could read ASM =/
<angelsl>
w00tc0d3: how big is the RIL?
<angelsl>
cause libsecion.so happens to be 5kb and i only need to decompile 4 short functions
<angelsl>
and that's already taking me a few hours
<w00tc0d3>
angelsl: it consists of rild, several libraries and java
<angelsl>
java?
<angelsl>
java is the easiest
<angelsl>
i wouldn't bother reversing the proprietary libsec-ril.so etc
<angelsl>
rild shouldn't be proprietary..

<rekoil>
ok, I have much more time today, anyone fancy helping me debug why my specific I9305N won't get any radio in codeworkx's CM10.1?
<rekoil>
seemingly others have radio, but no 4G
<w00tc0d3>
rekoil: maybe old modem, i dunno
<rekoil>
perhaps the problem is related
<rekoil>
w00tc0d3: thing is, there is only one modem available for the I9305N
<w00tc0d3>
=/
<w00tc0d3>
weird
<rekoil>
the only thing I can think of is that I have accidentally flashed an I9305 sboot.bin previously
<rekoil>
but then again, it works in I9305N rom
<rekoil>
so why not in I9305 sammy rom or I9305 cm10.1?
<rekoil>
waiting for a second sammy release to flash an I9305N sboot.bin
<rekoil>
I9305N is pretty special, only one carrier :P
<angelsl>
w00tc0d3: lol, the ARM decompiler

i wish i had it

we had access to that at idroidproject

<angelsl>
you "had access to that at"?
<angelsl>
like, someone had a copy of it?
<rekoil>
one group member had a friend who had access
<rekoil>
hehe
<rekoil>
one group member had a friend who had a copy*
<angelsl>
meh
<rekoil>
i wanna get rid of this stupid touchwiz crap
<rekoil>
:(
<a3Dman>
angelsl: how much is it?
<rekoil>
several thousand dollars
<angelsl>
^
<rekoil>
1800 EUR
<rekoil>
for just the ARM decompiler
<rekoil>
if you want that with a legit IDA licence you'll have to fork out 3099 EUR
<rekoil>
and then it's an extra 1799 EUR if you also want to decompile x86 code
<rekoil>
(that one can be gotten a hold of though *cough* *cough*)
finnq is now known as finnq|gone
<angelsl>
i already have IDA and the x86 decompiler *cough cough*
<rekoil>
so my radio problem, I guess my best bet is to wait for another full sammy release I suppose
<rekoil>
we should get 4.1.2 soon I reckon
<rekoil>
probably the last of the bunch to get it
<rekoil>
lol
<rekoil>
that will contain an I9305N sboot.bin (to fix exynos-mem) hole
<rekoil>
that will contain an I9305N sboot.bin (to fix exynos-mem hole)*
<rekoil>
stupid experimentation
<rekoil>
you don't know how happy and surprised I was when I realised my original rom worked
<rekoil>
because nothing else did
<rekoil>
other I9305 releases didn't work, cm didn't work, my original rom didn't boot (though that was due to data from updated sammy rom getting in the way)

We should open the project: OpenSourceAllTehSamsungThingys
<Espenfjo>
read and understand the kernel code, read and understand the framework. strace/ltrace the inbetweens. find out whats missing
KalimAz_ has joined #teamhacksung
<w00tc0d3>
Espenfjo: =/ I don't know how to use strace and ltrace
<Espenfjo>
strace -f -p <pid of rild>
<Espenfjo>
Then youll see all the system calls its doing
<Espenfjo>
same with ltrace (Except ltrace doesnt work on android)
<w00tc0d3>
ahh
KalimAz has quit [Ping timeout: 252 seconds]
<w00tc0d3>
let's google the differences between xmm6260 and xmm 6262 :) because xmm6260 is already supported in replicant
<w00tc0d3>
Espenfjo: But if you know the kernel part... You can write interfaces for it, and gather data using strace for the magic userspace is doing, right?
<Espenfjo>
Basically
<Espenfjo>
And if you know what the kernels needs/is doing, and you know what the framework needs/is doing you "just" have to figure out what has to be done inbetween
<Espenfjo>
simply enough
<w00tc0d3>
Espenfjo: Fortunately I only need to do libsamsung-ipc, paulk already did the layer ril <--> framework IIRC
<w00tc0d3>
does anyone knows which paramenters ioctl() needs?
