I agree that you don't need to like your job or employer, but... at the very least there does need to be cultural 'compatibility', whatever that means :-)
<wolfspraul>
if the company culture is a bunch of assholes raping the world, then you better have that same culture, and you will do well. equally for any other culture.
<DocScrutinizer05>
actually that's another reason i'm not entirely happy with the perspective: there are realy few shops and restaurants in this whole area
<wolfspraul>
I don't know the qualcomm company culture, but culture compatibility is something you should check, for everybodys happiness...
<wolfspraul>
the few qc people I met were all very professional and serious, I liked them
<DocScrutinizer05>
aiui my potentially new job would be more hw-centric :-D
<wolfspraul>
qc has also recently been restructuring their open source efforts
<wolfspraul>
don't know the thinking behind that though
<DocScrutinizer05>
ooh, they have a thing like opens source efforts?
<wolfspraul>
definitely, and they are restructuring it
<wolfspraul>
I *guess* they want to separate a little better from their IP businesses so that they can protect that IP better, and at the same time can invest in anything 'open' better
<wolfspraul>
but you need to talk with them, maybe you are soon one of them :-)
<wolfspraul>
then you can explain to us!
<DocScrutinizer05>
:-)
<DocScrutinizer05>
thanks for the tips!
<wolfspraul>
gotta run too
<wolfspraul>
how can you be up at 4.30 btw? :-)
<wolfspraul>
k l8...
<DocScrutinizer05>
I'm still vacant
<DocScrutinizer05>
my pimp threated me to call yesterday, to tell me about possible meeting at qualcomm on monday, but he didn't
<DocScrutinizer05>
threatened?
<DocScrutinizer05>
yeah
<DocScrutinizer05>
so otoh he "forced" me to take my remaining holiday for this year, which ends today
<DocScrutinizer05>
rather, yeaterday

(open effort) now that sounds like a departure from the past. if it's true, maybe they won't be that bad.

larsc: the current battery driver will use a negative (error code) voltage value in some cases
<mth>
this diff is for the 4770 driver, but that's almost an exact copy of the 4740 driver
<mth>
currently anyway: it doesn't work yet, so I'll probably have to add some more differences

mth: my plan is to add a IIO ADC driver for the jz4740 ADC and then eventually switch to the generic IIO battery driver (which currently is in development).
<larsc>
a sane strategy would probably to do the same for the jz4770
<kyak>
the most dangerous command is "uptime". as soon as i run it, it doesn't take long till something happens to my server

why does svn suck so much? Just found out that you can't set global ignores, but rather have to specify them for each directory...

did you remember about the INI library? :)
<larsc>
no
<larsc>
but I'm still at work
<viric>
[<bf2004f4>] (btrfs_num_copies+0xe8/0xf4 [btrfs]) from [<bf1bd89c>]
<viric>
what is 0xe8 and 0xf4?
<viric>
one should be the offset since the function entry point
<larsc>
the other is the size of the function
<larsc>
Ayla: So far I could find out that the header file is called ini.h
<viric>
ah 0xf4 is the size? nice.
<viric>
thank you
<larsc>
Ayla: but that's all I can find for the moment
<Ayla>
OK
<larsc>
more on monday. the person that's using it isn't in the office right now

hi sjhill
<sjhill>
larsc -> Lars-Peter Clausen
<sjhill>
hi
<larsc>
yes

mth -> Maarten ter Huurne
<larsc>
yes
<sjhill>
and....
<sjhill>
i have not idea where Thierry and Antony are
<larsc>
thierry acutally has nothing to do with jz47xx, he just brought over the pwm driver to the generic pwm framework since he is the pwm maintainer
<sjhill>
ah
<sjhill>
so i won't include him on future emails
<larsc>
and to be honest i don't know who Antony is
<sjhill>
lol
<Ayla>
you're doing a PWM driver for jz4770?
<larsc>
no
<larsc>
sjhill: is working on jz4760 support
<Ayla>
ah.
<sjhill>
larsc: how did you get a lepus board?
<larsc>
was a bit of a coincidence, I did a bit of contract work for somebody who wanted to sell a jz4760 based board
<sjhill>
i'll have to talk to my colleagues at MIPS and email my one contact at Ingenic
<sjhill>
maybe i'll get lucky
<sjhill>

mh what's that kernel config option, to have a populated /dev mounted before running init?
<viric>
(when rootfs doesn't have it)

viric: what version kernel?
<viric>
I looked for it in 3.5.3
<viric>
I recall it's about DEVFS something
<viric>
but F8 in nconfig does not show me any DEVFS thing
guanucoluis1 has quit [Ping timeout: 252 seconds]

DEVTMPFS
<viric>
ahh

damn. It's inside device drivers, not filesystems.
<mth>
larsc: Antony is doing an OpenDingux port for the Ritmix (Russian) game console (JZ4755)
<mth>
sjhill: Ayla has done a fair bit of kernel for for the 4740 as well, for example the watchdog driver was written by him
<mth>

So, who's going to send me one of those game consoles? :)
<sjhill>
$120US
<sjhill>
I'll buy one, if there are any left.
<Ayla>
there are
<Ayla>
if you're up to do some kernel work, you could ask for a prototype

<sjhill>
Sure.

hmm. i have small and fixed number of variables. from these, i want to determine the median value. i could sort the variables and pick the value in the middle, but that's quite inefficient. a more efficient approach is to directly search for the median value.
GCW2012 has joined #qi-hardware
<wpwrak>
i've solved this manually for three variables. doing it for five smells like messy work. i wonder if there's an algorithm for this somewhere ?
<wpwrak>
not sure yet. i very much hope it'll be enough. it has to run in a poor little microcontroller crawling at less than one MIPS
<mth>
the number of values is smaller than the range of the values?
<wpwrak>
yes, the range is much larger
<mth>
what you can do, is a limited type of quicksort
<mth>
every quicksort iteration separates the array into a segment where all elements are smaller than X, a segment where all elements are equal to X and a segment where all elements are greater than X
<mth>
if the "equals" segment is in the middle, you're done, otherwise continue to work on the largest remaining segment (the one that contains the middle element)
