May 16 15:53:44 <eveningland> Hey
May 16 15:55:27 <eveningland> I need help
May 16 16:15:40 <marex> good bye ... I don't care
May 16 16:16:47 <marex> jeez ... they think we'll be stuck to screen so we can help then right after they appear ... right
May 16 16:18:17 <bluelightning> marex: yeah... it's annoying
May 16 16:18:42 <bluelightning> I can't count the number of times I've been typing a damned reply and the person has quit :/
May 16 16:19:12 <marex> bluelightning, yeah
May 16 16:22:14 <marex> bluelightning, how's stuff going anyway ? Still in UK and planning on visiting CZ ?
May 16 16:22:49 <bluelightning> marex: yes and yes, at some point during my time here
May 16 16:23:36 <bluelightning> things are going OK, I should probably be doing things other than hacking on weekends... but who else is going to do it :)
May 16 16:23:53 <bluelightning> you?
May 16 16:39:50 <marex> bluelightning, examination period approaches again ...
May 16 16:40:03 <marex> I should probably be doing other things than hacking on linux kernel in my free time ;-)
May 16 16:40:08 <bluelightning> :)
May 16 16:40:11 <bluelightning> feeling confident?
May 16 16:40:15 <marex> (like finally getting a gf)
May 16 16:40:31 <marex> bluelightning, well ... dunno, I have a few hard exams this time
May 16 16:40:49 <marex> but I'm looking forward to summer holiday
May 16 16:41:00 <marex> I'll hack on openbsd kernel, then hack on linux kernel
May 16 16:41:23 <marex> and maybe I'll get a SBC from embeddedarm.com to hack on it :-)
May 16 16:41:32 <bluelightning> openbsd? what attracts you to work on that specifically?
May 16 16:41:56 <marex> bluelightning, actually ... the license makes me want to puke
May 16 16:42:23 <marex> bluelightning, but I was very curious and started porting it to palm hardware ... then it evolved into university project
May 16 16:42:34 <marex> so I have to finish it ...
May 16 16:42:38 <bluelightning> ah I see
May 16 16:42:49 <bluelightning> would you say the kernel code is cleaner than linux?
May 16 16:42:56 <marex> an openbsd was the choice because it's the most secure of all those *bsds
May 16 16:43:06 <marex> bluelightning, nope ... for arm it's terrible mess
May 16 16:43:25 <bluelightning> do people use it a lot on arm?
May 16 16:43:26 <marex> but the kernel code is (not really) surprisingly very simple
May 16 16:43:50 <marex> bluelightning, I know of a few people who use it on zaurus, but no, linux has majority there
May 16 16:44:05 <bluelightning> hmm ok, interesting
May 16 16:44:57 <marex> bluelightning, also, the openbsd kernel code lacks any real abstraction
May 16 16:45:03 <marex> it's not so modular like linux either
May 16 16:47:55 <bluelightning> I guess that makes it easier to audit for security
May 16 16:49:25 <marex> bluelightning, that's indeed true ... actually iirc openbsd was sponsored by NSD
May 16 16:49:27 <marex> *NSA
May 16 16:49:53 <marex> bluelightning, NSA paid them to audit the code of netbsd and create very secure OS for them
May 16 16:50:34 <marex> bluelightning, but then, Theo (the project head) said something about war in iraq (maybe some other country) and they cut the funding
May 16 16:50:51 <bluelightning> heh... politics
May 16 16:51:07 <marex> yea, but ever since then OpenBSD is not sponsored
May 16 16:51:19 <marex> also ... it seems the core crew of openbsd changed quite a bit
May 16 16:53:06 <marex> bluelightning, well ... OpenBSD is "corporate opensource" ... that's wicked combination, don't you think
May 16 16:53:37 <marex> (but I can't spew sh*t about OpenBSD since I want to become part of their community and gain commit access to their kernel tree ;-) )
May 16 16:53:56 <bluelightning> heh, good luck :)
May 16 16:54:53 <marex> bluelightning, thanks :-) same to you
May 16 16:56:07 <WyrM> openbsd is nice. :)
May 16 16:56:21 <WyrM> have you added palm to it already?
May 16 16:56:30 <WyrM> marex, bluelightning: hi! :)
May 16 16:56:40 <bluelightning> hi WyrM
May 16 16:58:30 <marex> WyrM, http://marex.hackndev.com/OpenBSD
May 16 16:58:35 <marex> see the photo
May 16 17:04:24 <WyrM> marex, nice, good work! :)
May 16 17:04:50 <marex> thanks
May 16 17:05:58 <marex> WyrM, what are you up to recently? what are you working on ?
May 16 17:06:48 <WyrM> misc fixes, and still fighting generic irq on sleeping context :)
May 16 17:06:55 <WyrM> but I think I got it right now.
May 16 17:07:13 <marex> WyrM, I see :-)
May 16 17:07:27 <marex> good luck ... I tried fighting the AC97 problem as you might have noticed
May 16 17:07:45 <marex> though most of the discussion went through #alsa-soc
May 16 17:08:46 <WyrM> I keep fighting pH5 (and others) because of pxa-ssp.c too. :)
May 16 17:08:58 <WyrM> too many workarounds for specific hardware.
May 16 17:09:04 <marex> WyrM, ah ... slay him for me too ;-)
May 16 17:09:10 <WyrM> I have to change my code all the time.
May 16 17:09:11 <WyrM> :)
May 16 17:09:34 <marex> WyrM, I'm thinking of patching mainstone-wm97xx.c to get IRQ driven touchscreen support
May 16 17:09:44 <marex> it might help the system load a little
May 16 17:11:20 <WyrM> currently its polling only?
May 16 17:12:53 <marex> WyrM, yup
May 16 17:16:27 <marex> WyrM, I think making it interrupt driven will help
May 16 17:16:38 <marex> since the system is slow in itself enough already
May 16 17:16:45 <WyrM> sure it will.
May 16 17:17:04 <WyrM> the I/O to the chip sleeps?
May 16 17:17:24 <WyrM> its ac97 bus isn't it?
May 16 17:18:38 <marex> yeah
May 16 17:19:12 <marex> WyrM, it'd be cool if we could implement some fine-grained power management for the wm97xx-series chip
May 16 17:19:38 <marex> the chip can enter low-power mode very fast and getting it back up and running is fast too ...
May 16 17:20:09 <marex> I dunno if it can wakeup on touchscreen irq though, but from what I saw in the docs it can ... so it'd be cool
May 16 17:20:33 <WyrM> yeah, our pmic can interrupt pxa on touch too.
May 16 17:20:53 <WyrM> does wm97xx support dvs too?
May 16 17:21:41 <WyrM> btw, I found a chip with public datasheet that is very similar to our (PCAP2, PTWL93017 from TI made as a "custom" product for motorola).
May 16 17:22:13 <WyrM> its the ATLAS PMIC from freescale (MC13783)
May 16 17:27:14 <WyrM> "found the problem is in the specific version of bootloader, it does some GPIO setup during wakeup"
May 16 17:27:46 <WyrM> heh, that's why I patch the bootloader for resume. No surprises. :)
May 16 18:05:04 <marex> WyrM, but many people won't like this approach
May 16 18:05:47 <marex> they won't like to risk of damaging their devices
May 17 00:49:07 <marex> bluelightning_, hi, j/w what's the time at your place ? ;-)
May 17 00:49:15 <marex> why are you here so late ?
May 17 00:52:41 <bluelightning_> marex: it's 1:52 am... just talking to my sister on skype
May 17 00:52:54 <bluelightning_> (it's 12:52 pm in NZ)
May 17 01:09:06 <marex> looks like skype sux ;-)
May 17 01:14:00 <enigme> indeed
May 17 01:15:36 <enigme> btw, marex, why are you here so late? ;)
May 17 01:16:53 <enigme> it's 1800 or so in my timezone, so it must be what, 0200 where you are?
May 17 01:33:31 <marex> 0333
May 17 01:33:44 <marex> it's GMT+1 here
May 17 01:35:01 <flyback> http://www.reflexmusic.de/DSS-1/
May 17 01:35:03 <flyback> this is the shit
May 17 01:39:35 <enigme> marex: then late isn't the right word to use :P
May 17 01:55:56 <marex> damn ... it's getting bright outside already
May 17 01:56:03 <marex> time to go zzz
