ijc: could we get rid of CONFIG_SUN?I as well (using CONFIG_TARGET_SUNxI)?
<ijc>
wens: Do we have CONFIG_SUN?I in maniline -- I'm not seeing it.
<ijc>
Oh wait, there it is
<ijc>
Yes, I think we can and should move as you suggest.
<ijc>
I suspect that the majority of include/configs/sun?i.h can/should become Kconfig based.
<wens>
however it would make some of the #ifs in various drivers very long
<wens>
yeah, i was looking at it earlier

ijc: i only mention it because i keep adding them ...
<ijc>
wens: I think the solution is either to move those strings of SUNxI || SUNyI into specific Kconfig options (select'd by TARGET_SUN[xy]I) or to pull them up into ifdef's which define a more specific define. Probably the former...
<wens>
the former sounds good
<wens>
SUNXI_GEN1 (sun457i), SUNXI_GEN2 (sun68i), and so on
<ijc>
wens: I was thinking more along the lines of SUNXI_SMP_AUXREG and SUNXI_HAS_A_THING, i.e. specific h/w features, but perhaps a more umbrella generational approach would work too. I prefer the former since it is more specific and somewhat less of an artificial construct.
<ijc>
I'm seeing a mixture of SUN4I||SUN7I and SUN5I||SUN7I In the current code, which doesn't seem to fit the generaiton pattern (but the existing ones are wrong)
<wens>
there are a few things that are generational, like a31 started to have reset controls, R_PIO, PRCM, separate RTC block and stuff
<wens>
memory map is slightly different as well
<wens>
the smp stuff keeps changing

castor3: Not sure which platform you are on but I think if you can arrange to boot the kernel+initrd from ftp://ftp.debian.org/debian/dists/jessie/main/installer-armhf/current/images/network-console/ with bootargs "hostname=mysunxi domain=mydomain network-console/password=password network-console/password-again=password" then you *should* be able to ssh to installer@<DHCP address> with password "password" and run through the Debian installer from there.
<ijc>
Main problems would be if d-i wants to ask you some other question before it launches the ssh server (in which case without serial you'll never see it) or if e.g. flash-kernel doesn't support your board, in which case the resulting fs may lack the /boot/boot.scr which would launch things for you. I suspect you could work around the latter by providing your own script etc.
<ijc>
I only tried this for the first time ~5mins ago on a cubietruck, so YMMV...
<wens>
didn't know we had installer support already :)

nove: it possible to ask tom send us ks devboards, but I unsure where I can find time to for it
<wingrime1>
*rk
<wingrime1>
Still mainlining for me is dark matter, and it main work field
<nove>
wingrime1: well you know about the position of libv about jumping from soc to soc
<nove>
but i also wonder how serious is allwinner, about working with the community
<libv>
not very
<wingrime1>
nove: I think libv, isnt going work with powervr
<libv>
unless they act soon, i will open the taps on the gpl violation mess.
<libv>
wingrime1: atm, i do not care about a gpu
<libv>
these crap chinese companies jump gpus like most big open source noise makers jump SoCs
<wingrime1>
yes, but rk much like sunxi in old days
<wingrime1>
Many fields for hacking, nor mainlineing
<libv>
who wants to go fix everything and fill up the wiki on linux-rockchip.info?
<libv>
and even then
<libv>
what will rockchip do next, if they do anything at all?
<libv>
and then what?
<wingrime1>
No rk hw with it on hands
<wingrime1>
libv: they looks like open vpu
<wingrime1>
libv: thats make some impression to me
<libv>
wingrime1: go.
<nove>
wingrime1: if you saw the source, they still have a proprietary license, not really open source
<libv>
but at least put your back into it and don't just talk
<wingrime1>
libv: I wait some actions from aw
<wingrime1>
libv: and still not going anywhere
<libv>
well, i will be acting on the gpl violations issue in the coming week
philippe_fouquet has quit [Remote host closed the connection]

libv: thats I wanted to hear from you in a first place)
eebrah|mobile has joined #linux-sunxi

<nove>
wingrime1: what is?
<wingrime1>
w
<wingrime1>
Do you know about IDA?
<wingrime1>
nove:^
<nove>
wingrime1: the disassembler tool?
<wingrime1>
Yes, good news, arm decompiler finaly leaked to web
<wingrime1>
I mean, decompiler to C code for arm
paulk-collins has quit [Ping timeout: 245 seconds]
eebrah|mobile has quit [Ping timeout: 260 seconds]
<wingrime1>
There was only x86 decompiler in ida recenty,
<nove>
wingrime1: i don't use it, never used it
<wingrime1>
So if you don't know arm asm, it can be usefull
<wingrime1>
nove: thats best tool looking into the blob
<nove>
wingrime1: no need for me, any assembly language is equal with the instruction set manual open
<wingrime1>
nove: yes it does, but decode some math code takes much time to.understand
Gerwin_J has quit [Quit: Gerwin_J]
<nove>
wingrime1: but i never did, or will look at the blob
<wingrime1>
nove: if I will have some time I try look into h264 encoding blob again
<nove>
wingrime1: you know what could maybe be useful, would be to get a irrefutable proof of the gpl violation
<wingrime1>
nove: what kind of proof you confider irrefutable?
<nove>
wingrime1: find a some small function, and do a comparation between the assembly and the correspondent source code

wingrime1: explained in detail, find a ffmpeg function inside the blob, and track the must similar source code that matches, and do a comparison to prove the use of ffmpeg in blob
<wingrime1>
nove: good idea
RzR is now known as rZr
<nove>
wingrime1: and add this comparison (blob disassembly arm instruction => ffmped source code) to the wiki
<nove>
wingrime1: this will be usefull, because there are people that doen't believe that a gpl violation exists
Andy-D has joined #linux-sunxi

rellla: have you noticed, that that code seems redundant? like a=x*2/x
<ssvb>
allwinner is not alone violating the ffmpeg/libav license, they are in a large and happy company of other violators
<wingrime1>
ssvb: yes, more one line in that list, only thing that realisticly can be happen
<wingrime1>
In recent time
<ssvb>
and the ffmpeg/libav developers don't seem to be willing or able to do any license compliance enforcement other than just listing the offenders on that page
<wingrime1>
ssvb: are you touched rk hw?
philippe_fouquet has joined #linux-sunxi
<ssvb>
I have no rk hardware
<ssvb>
but will probably get something with a cortex-a17 cpu eventually (not necessarily rk)
<wingrime1>
Situation with voliation are same for all china socs

Maybe only freescale better in some ways

worst than allwinner, is those board makers that weave the open-source friendly flag and simultaneously have no problem using the software with this license issues

Nove: best opensource looks like some open risc soc project
<wingrime1>
When verilog code avaliable)

for me would be enough respecting the licenses used
<nove>
been them opensource licenses or proprietary licenses
<wingrime1>
nove: soc building it self very intetest for me
<wingrime1>
When you load cpu to fpga and launch
<nove>
wingrime1: also for me. but is still not possible to do at home
<wingrime1>
Why no, there much cheap fpga devboard
<wingrime1>
If you are student altra boards will be much cheaper
<wingrime1>
For you
<nove>
fpga is a "simulator", not the real thing
gzamboni has joined #linux-sunxi
<wingrime1>
Asic production indeed not sutable for home scale, but there much expensive quipment that uses a plenty fpga's, just only becose asic is not sutable for small scale prodution

I have luck use it, and when it boot system it even shows "loading fpga firmware.." messages

hno: fpga are best for small size productions
<wingrime1>
hno: some huge speed data crunching can't be make without it
<nove>
hno: yes you know, but is not possible to reach the level of performance (clock frequency) of the "real thing"
<wingrime1>
Yea, but moving from fpga to asic is straitforward
<hno>
I know. But the FPGA allows very tight integration with I/O to a level that can not be acheived using off-the-shelf CPUs. CPU clock speed is not very important for many applications.
<hno>
Sure, it makes no sense to build a desktop or general purpose server with an FPGA based CPU, but very many other applications makes a lot of sense.
<nove>
what is needed is a 3d printer capable of disposing single atoms within some tolerance
<hno>
nove, wouldn't help. You also need it to stay put..
