15:20.05T0mWprpplague: what do you use to debug a running kernel? gdbserver?  or, can I use jtag?
15:20.13T0mWprpplague: btw, gm
15:20.18T0mWheh
15:20.41prpplagueT0mW: kgdb is what i mainly use when i need something of that level
15:20.55prpplagueT0mW: but generally i can debug most issues with simple printks
15:21.12T0mWprpplague: yeah, sprinkle the func with printks
15:21.30prpplagueT0mW: yea, i'm a printf/printk freak
15:22.41prpplagueT0mW: i usually do one of two things, either do a "define debug" option at the beginning of the code or i make all the printk's with a comment field which i can do a regex on
15:23.07T0mWprpplague: I am trying to use EINT11 but kernel/irq/manage.c is failing me at:    if (old) {
15:23.07T0mW<PROTECTED>
15:23.07T0mW<PROTECTED>
15:23.07T0mW<PROTECTED>
15:23.07T0mW<PROTECTED>
15:23.15T0mWprpplague: are you mapping EINT11 for something?
15:24.11prpplagueT0mW: how are you requesting the IRQ?
15:25.01T0mW<PROTECTED>
15:25.16T0mW<PROTECTED>
15:25.41T0mWessentially, using the irqs.h macro to request #55
15:26.07prpplagueT0mW: EINT11 is configured for the push button on the carrier board
15:26.15T0mWAHA,
15:26.19T0mWthanks!
15:26.19prpplagueT0mW: do you have the push button driver enable in the kernel?
15:26.32T0mWprobably, heh, haven'
15:26.33T0mWt
15:26.44prpplagueT0mW: ?
15:27.01T0mWprobably do, thank you!
15:27.06prpplagueT0mW: okie dokie
15:27.22T0mWprpplague: how's Donna doing?
15:27.36prpplagueT0mW: doing well, she's a little homesick, but not too bad
15:27.56T0mWnod, well, your family is now settled? all that crap over now?
15:28.01prpplagueT0mW: $$ has been a little tight since we've been buying a ton of stuff for the house
15:28.06T0mWheh
15:28.12prpplagueT0mW: yea, well, it still continues on
15:28.21T0mWprpplague: plus spending mucho money on having a child
15:28.36prpplagueT0mW: we had problems getting her state id because a bunch of illegals have been using fake documents
15:28.43T0mWyeah
15:28.57T0mWI think that we should just annex mexico
15:29.00T0mW:P
15:29.01prpplagueT0mW: plus, we had problems getting her SS#
15:29.21prpplagueT0mW: and on top of that, they had her entry date into the US wrong
15:29.54prpplagueT0mW: normally we wouldn't care about the date, but it would have pushed her elagability for US citizenship back by 6 months
15:31.48T0mWoh yeah, documentation is key.  I have a friend, a brit, who has a permanent visa (?), and he had to jump through hoops just to get his drivers license renewed.  They kept claiming that his residency card needed an expiration date on it.
15:32.05T0mWI probably got the names of the docs messed up, but you know what I mean
15:32.33T0mWHe is considering, finally, becoming a US citizen after living here for 22 years.

15:34.38prpplagueT0mW: yea, its a real pain
15:35.04prpplagueT0mW: funny thing is, they make it really difficult for people are here legally, but illegals are given a free ride

16:00.28prpplagueCosmicPenguin: i see the XO is now on sale
16:01.13CosmicPenguinif you're going to spend a thousand dollars, buy a desktop
16:01.39prpplagueCosmicPenguin: why's that?
16:02.09CosmicPenguinBecause its a better value? :)
16:02.59prpplagueCosmicPenguin: hmm
16:03.11prpplagueCosmicPenguin: surprised, i figured you'd want to sell XO's
16:03.40CosmicPenguinI don't want you to spend that kind of money for what you get
16:03.58CosmicPenguinI am not at all on board with the commercial sales idea - I think its doomed to failure
16:04.32prpplagueCosmicPenguin: well i had planned on purchasing two $400 laptops, just kinda figured i'd get the XO since it was running linux
16:04.40CosmicPenguinso is the eee
16:05.03CosmicPenguinOr you can get some way cheaper Geodes, though they are not mobile
16:05.19prpplagueCosmicPenguin: eee the asus laptop?
16:05.43CosmicPenguinyeah
16:06.10prpplagueCosmicPenguin: yea i looked at it, but it didn't seem like anyone had them yet
16:06.28CosmicPenguinCostco does
16:07.02prpplagueurl?
16:07.47prpplagueCosmicPenguin: nm googled
16:07.55prpplagueCosmicPenguin: never heard of costco before
16:09.09CosmicPenguinnoo?
16:09.22CosmicPenguindo they not have them in texas?
16:10.04prpplagueCosmicPenguin: yea looks like they have about 8 in texas
16:10.13prpplagueCosmicPenguin: there is one about 30 miles from my house
16:10.42CosmicPenguinI thought everybody was a costco member
16:10.55CosmicPenguinat least, everybody seems to be shopping there on a saturday afternoonn
16:11.06prpplaguehehe
16:11.11prpplagueCosmicPenguin: good buys there?
16:11.32prpplagueCosmicPenguin: i was once a member for sams club, but i didn't find their prices really any good
16:12.35CosmicPenguinThey do okay for prices
16:13.02prpplaguehmm, wonder if anywhere has the Eee
16:13.41CosmicPenguinI'm lazy - if I know i'm going to be making a chicken dish a week, I'm more into buying 10 weeks worth of chicken
16:15.34prpplagueCosmicPenguin: yea, we bought a chest freeze for the garage
16:15.39prpplagueargh!!!! - http://www.foxnews.com/story/0,2933,310542,00.html
16:16.04prpplaguethat just makes me want to scream

16:52.11T0mWsomeone explain something to me, please.  I have a sysfs into which I have an I2C device that is supposed to be at 13:65 (Major:Minor), but when I insert the module, the device appears in /sys but no entry is made into /dev/
16:52.16T0mWwhat am I missing?
16:52.37T0mWshouldn't the /dev entry be automagically done?
16:55.28T0mWthe device works, a cat /dev/touch gives data
16:55.28*** join/#edev ico2 (n=ico2@modem-1145.cougar.dialup.pol.co.uk)
17:03.54prpplagueT0mW: sysfs is different that devfs
17:04.04prpplagueT0mW: you have to create dev nodes yourself
17:05.11T0mWprpplague: ok, would that devnum always be the same: 13:65?  I registered as "  idev = input_allocate_device()"
17:05.49prpplagueT0mW: more than likely
17:06.07T0mWhmm
17:32.03adyer_i thought devfs was dead and udev was the new thing?

19:45.33prpplaguechouimat|work: started new job yet?
19:45.57chouimat|workprpplague: reading the user manual of the product and playing with it and cursing vista
19:46.35ds2morning
19:49.35T0mWchouimat|work: you did get more money becuase it was a Windows job, right?!
19:50.27T0mWchouimat|work: Prozac isn't cheap
19:51.37chouimat|workT0mW: it's a linux job, i have to use windows because of something called exchange ...
19:51.45ds2'hazard pay'? ;)
19:52.06chouimat|workds2: hehe
19:52.24chouimat|workT0mW: and my linux development box is not ready yet
19:52.30T0mWchouimat|work: well, lie and say that you don't know windows and that they need to hire an intern to help with that stuff

19:53.44T0mWprpplague: yup
19:53.49ds2triple all estimates to cover delays due to exchange
19:53.52chouimat|workT0mW: I simply installed vmware and RHEL4
19:53.52prpplagueT0mW: question
19:54.23prpplagueT0mW: got a device that can be configured with a resistance to one of the pins to ground
19:54.27prpplagueT0mW: one sec phone
19:54.32T0mWprpplague: k
19:54.44chouimat|workT0mW: i don't like rhel4 much but it a little more useable ;)
19:55.05ds2any comments from this crowd on the android stuff?
19:55.08T0mWchouimat|work: Mandriva 2007.1 and 2008.0 here
19:55.45T0mWds2: 'droids are very good for doing drudge work, like soldering parts onto boards that I design
19:55.54T0mW:P
19:55.57ds2=)
19:56.17ds2would think ovens are cheaper ;)
19:56.29chouimat|workT0mW: they gave me a laptop this morning so I have to use it ... I guess tonight I will simply install opensuse 10.3 in vmware so I could have a nice env
19:56.56T0mWchouimat|work: why not install Suse on the laptop, then vmware the Windows?
19:57.21chouimat|workbecause I don't have the winblows cd
19:58.21T0mWchouimat|work: dd if=/dev/<windows partition> of=<filename.img>
19:58.40T0mWchouimat|work: there must be a way!
19:58.52chouimat|workyeah there must be a way
19:58.59T0mWchouimat|work: what laptop they give you?
19:59.13ds2just tell them, switch to a working mail system or else ;)
19:59.15prpplagueT0mW: ok sorry back
19:59.24chouimat|workhp pavillion dv2000
19:59.38prpplagueT0mW: any way i have a device, that can be configured with variable resistance to ground
19:59.55prpplagueT0mW: i want to be able to control this via a gpio
20:00.05prpplagueT0mW: what i'm think i'm is to have two conditions
20:00.21prpplagueT0mW: first being a 1.6k to ground , and the second to be shorted to ground
20:00.36prpplagueT0mW: so what i was thinking is go ahead a populate a 1.6k to ground
20:01.04prpplagueT0mW: then have a transistor controlled by a gpio to pull to ground
20:01.20prpplagueT0mW: that way if you short to ground you by pass the 1.6k
20:01.27prpplagueT0mW: that sound right to you?
20:01.42ds2prpplague: Vsat isn't going to cause problems for you?
20:01.47ds2or you going FET?
20:01.57prpplagueds2: i'd use a FET
20:02.16ds2ah.. so you have enough drive to keep Rds down?
20:02.58prpplagueds2: yea, basically poormans level shifter similiar to what sparkfun uses on some of their boards for rs-232 translations
20:03.14ds2gotcha
20:03.15T0mWprpplague: yes, I would use a MGSF1N03LT1GOSCT or similar 3v FET
20:04.03T0mWprpplague: 2n7003 might work, but the spec is marginal at 3v gate voltage
20:05.02prpplagueT0mW: yea thats what i was thinking
20:05.13prpplagueT0mW: thats one of our stock parts
20:05.26T0mWprpplague: cool
20:05.38prpplagueT0mW: (the 7003 that is)
20:05.43T0mWoh
20:06.36T0mWprpplague: like I said, it should work, I am just not confortable with the Vgs control plot
20:06.40prpplaguehmm, mouser doesn't carry that
20:06.46T0mWprpplague: digikey
20:06.52prpplagueahh
20:07.01ds2why not be wasteful and use a CMOS switch?
20:07.07T0mWheh
20:07.21prpplagueT0mW: but the concept holds true?
20:07.25T0mWds2: soak up .3 sq in of PCB
20:07.27T0mWprpplague: correct
20:07.40ds2oh space constrained...heh
20:07.57T0mWprpplague: when the device is "off", the drain is high-impedance
20:08.10T0mWs/drain/channel
20:08.45ds2don't FET's have a protection diode from S to D?
20:11.11prpplagueT0mW: what about a 2n7002 ?
20:11.31prpplagueT0mW:  http://search.digikey.com/scripts/DkSearch/dksus.dll?Detail?name=2N7002LT1GOSCT-ND
20:16.16T0mWprpplague: either one, that 2n7002 looks ok
20:16.46prpplagueT0mW: yea, the 2n7002 is what sparkfun uses as a level shifter from 3.3v to standard rs-232
20:16.53prpplagueT0mW: sorry 5v rs-232
20:17.41prpplaguehttp://www.sparkfun.com/datasheets/RF/BlueSMiRF-Extended_v1.pdf
20:18.49T0mWprpplague: well, you would definately need a pullup resistor on the gate whichever device you choose, you need that solid 3.3v on the gate.
20:19.21prpplagueT0mW: yea, as long as i know it's doable
20:22.06T0mWprpplague: btw, this worked pretty well for a quickie checkout of ts controller: "cat /dev/touch | hexdump"
20:22.22prpplaguecool
20:22.32T0mWprpplague: I just love Linux, "it's in there..."
20:22.45prpplagueT0mW: hehe, not always
20:22.49T0mWlol
20:23.05T0mWyeah, right, there are "few" drivers that still need to be written
20:23.56prpplagueT0mW: there are always new items that need drivers
20:32.30adyer_for your device with the control pin, if it doesn;t drive too high and doesn't try to source too much current, you could put a 1.6K to ground and just short the pin to ground with a GPIO
20:33.17adyer_for a multi resistance device like this i've used an analog mux with a bunch of R's
20:33.36prpplagueadyer_: yea i thought about that, not sure how much crrent its going to source
20:33.43prpplagueadyer_: i'll have to do some tests
20:33.48*** join/#edev chouimat||work (n=mchouina@firewall.oeone.com)
20:34.10adyer_use the fet, it's safer :-) we use a lot of FDV301 for stuff like this
20:34.13prpplagueadyer_: yea we are pretty space restricted
20:34.34prpplagueadyer_: yea i'd not use a direct gpio on production
20:35.09prpplagueadyer_: i'll probably try using the 2n7002 first since we have 50k+ in stock
20:35.34adyer_whats the vgs(on)?
20:35.54T0mWadyer_: depends on the drain current
20:37.53T0mWadyer_: oooo!  I like that FDV301!
20:38.20T0mWprpplague: you could prolly not have to use a pullup with that device
20:39.00prpplagueT0mW: yea, i'm seeing alot better choices, might have to bite the bullet and stock a new part
20:42.27prpplagueT0mW: i'll probably give the 2n7002 a try first
20:42.55prpplagueT0mW: any other ideas on a quick and easy way to control that?
20:43.49T0mWprpplague: naw, that is the best way if you need 0Ohm to 1.6KOhm on that pin
20:43.58T0mWs/to/or
20:44.15prpplagueT0mW: okie dokie thanks, i'll give it a try
20:53.04T0mWprpplague: you do know that the hammer_spkr is broken, right?
21:01.00adyer_lol, I can imagine what would happen if our techs heard hammer and speaker in the same sentence ;-)

21:33.51prpplagueT0mW: what?
21:35.11T0mWprpplague: it doesn't send a square wave to the transducer and the frequency settings don't result in what you ask for
21:35.38prpplagueT0mW: the value passed to that isn't a freq, its just an odd ball
21:36.07T0mWprpplague: right, but the transducer on the hammer carrier requires a 50% duty cycle
