Feb 01 03:00:46 <dyoung-away> lennert, do you NFS mount stuff from one xen instance to another?
Feb 01 03:01:04 <dyoung-away> its ludicrously slow for me.
Feb 01 03:01:12 <dyoung-away> was wonderingi if theres some trick I dont know....
Feb 01 03:03:27 <lennert> nope, i just have a big LVM VG in the dom0, and have LVs for each instance
Feb 01 03:03:43 <dyoung-away> that seems to be pretty fast.
Feb 01 03:03:55 <dyoung-away> nfs mounting from instance to instace really really sucks
Feb 01 03:04:03 <lennert> wonder why that is
Feb 01 03:04:12 <dyoung-away> what is the recommended way for sharing a disk resource?
Feb 01 03:04:13 <lennert> perhaps because it involves a lot of switching between instances
Feb 01 03:04:35 <lennert> send packet from instance a to b: switch from a to dom0, from dom0 to b, b makes reply, switch from b to dom0, from dom0 to a
Feb 01 03:04:42 <lennert> not sure.. maybe gfs? :)
Feb 01 03:06:20 <dyoung-away> hmm
Feb 01 03:06:39 <lennert> or ocfs, since that's being merged now
Feb 01 03:06:46 <lennert> i've tried ocfs in the past between qemu instances, and that worked well
Feb 01 03:06:48 * dyoung-away googles
Feb 01 03:07:11 <lennert> i need to hack up a way to do block device emulation over pci
Feb 01 03:07:33 <lennert> my ixp boards could use that instead of nfs root
Feb 01 03:07:50 <lennert> okie, i'm off to work
Feb 01 03:07:59 <dyoung-away> have fun working. :-)
Feb 01 03:08:03 <dyoung-away> and have a great day !
Feb 01 04:31:39 <lennert> thanks :)
Feb 01 04:46:28 <lennert> dyoung-away: did you get pong running yet?
Feb 01 06:11:29 <prpplague> well i have a dlpdesign ft2232 chip on the way
Feb 01 06:11:38 <prpplague> gonna try some jtag stuff with it
Feb 01 06:16:17 <vmaster> nice
Feb 01 06:17:26 <prpplague> vmaster: hehe got a lot of work to do in the next few months
Feb 01 06:17:43 <prpplague> vmaster: we are moving _all_ of our hardware peripherals to an SPI interface
Feb 01 06:17:58 <prpplague> vmaster: i should qualify that, all except the lcd
Feb 01 06:19:58 <vmaster> hehehe
Feb 01 06:21:59 <prpplague> vmaster: we are trying to get all our peripherals generic so we can cut down on dev time when need to do a new custom product
Feb 01 06:42:58 <lennert> dyoung-away: i mailed "kung hee fat choy" to a chinese friend of mine.. he had no idea what i was talking about :)
Feb 01 06:43:33 <dyoung-away> Weird.
Feb 01 06:44:00 <lennert> he asked if it was mandarin or cantonese
Feb 01 06:44:19 <dyoung-away> http://en.wikipedia.org/wiki/Chinese_New_Year
Feb 01 06:45:47 <dyoung-away> Thats cantonese.
Feb 01 06:47:08 <dyoung-away> I guess the more proper translation is "live long and prosper" :-)
Feb 01 09:38:07 * fishhead watches his mailbox like a hawk for his ppc board
Feb 01 09:55:38 * fishhead is in so much pain between his IBS and planars fascitious, he is about to pass out
Feb 01 11:42:08 * fishhead my ppc board didn't come :(
Feb 01 11:42:51 <fishhead> anyone here done serial bootstrapping with m68k, espically dragonball series??
Feb 01 12:27:57 * fishhead heads off to clean the last of his assorted circuit boards, memory chips, etc so can he can actually start testing this shit and move on
Feb 01 12:28:48 * fishhead bbl
Feb 01 15:47:12 <AchiestDragon> http://www.whipy.demon.co.uk/sch.pdf   , schematics tidy now (and starting to resemble a small book )
Feb 01 15:50:42 <ka6sox-office> :)
Feb 01 16:18:37 <ka6sox-office> those printed out nicely
Feb 01 16:19:50 <AchiestDragon> got to remeber to set the background to white rather than an off white to save ink 
Feb 01 16:21:29 <ka6sox-office> that would help with ledgability
Feb 01 16:23:48 <AchiestDragon> do you want detailed circut discriptions also 
Feb 01 16:24:01 <ka6sox-office> yes please.
Feb 01 16:27:41 <AchiestDragon> will do some once i get a couple of the jtag adaptor boards done  ,  a 20pin arm , a 10 pin altera , the 12 pin arm , the main ones atm , although there will be some user patchable ones for custom jtag formats 
Feb 01 16:28:18 <ka6sox-office> 6pin is the most common for me.
Feb 01 16:28:23 <ka6sox-office> (the digilent one)
Feb 01 16:28:39 <ka6sox-office> all of my fpga/cpld boards use that.
Feb 01 16:28:46 <AchiestDragon> theres the altera  10pin isp/icp one that i would like to do also 
Feb 01 16:28:54 <ka6sox-office> good plan
Feb 01 16:29:50 <AchiestDragon> i think if i stick to layouts covered in the chip data sheets for diferent manufacturers as std ones then that should be the best plan 
Feb 01 16:30:11 <ka6sox-office> ya
Feb 01 16:30:20 <ka6sox-office> this one (the digilent one) is used by a lot of boards.
Feb 01 16:30:34 <ka6sox-office> Xilinx projects.
Feb 01 16:31:16 <AchiestDragon> altera use a 10 pin connector for jtag and isp but the isb uses some reverced signals so will need 2 adaptors , do xilinx use a recommended programer pinout for all there devices 
Feb 01 16:31:30 <ka6sox-office> yes
Feb 01 16:31:44 <ka6sox-office> I can give it to you or you can download the information from digilent.
Feb 01 16:31:53 <ka6sox-office> (probably better to get it from the horse)
Feb 01 16:31:58 <ka6sox-office> I'll get a URL
Feb 01 16:32:05 <AchiestDragon> k , kool
Feb 01 16:34:35 <ka6sox-office> http://www.digilentinc.com/Data/Products/S3BOARD/S3BOARD-sch.pdf
Feb 01 16:34:56 <ka6sox-office> there are 2 on that board but we want the 6pin inline :)
Feb 01 16:37:53 <AchiestDragon> what format connector   ,, a .1" pinstrip ? any latching or polarisation 
Feb 01 16:38:02 <ka6sox-office> nope
Feb 01 16:38:08 <ka6sox-office> unfortunately
Feb 01 16:38:17 <ka6sox-office> but its marked with a square pin.
Feb 01 16:38:34 <AchiestDragon> k  , but std .1" pitch 
Feb 01 16:39:16 <ka6sox-office> yes
Feb 01 16:39:28 <ka6sox-office> single berg strip
Feb 01 16:39:40 <AchiestDragon> k
Feb 01 16:39:42 <AchiestDragon> np

Feb 01 19:45:48 <AchiestDragon> so using a straight type , mounted hoizontal  with the board between the pins , each row soldered to each side of the board  for the adaptors 
Feb 01 19:47:12 <fishhead> http://www.jumpers.computed.net/
Feb 01 19:48:32 <AchiestDragon>  PCB thickness is 1.6mm, unless we specify otherwise
Feb 01 19:49:23 <ka6sox-office> sounds good.
Feb 01 19:49:33 <ka6sox-office> easy to solder on without movement
Feb 01 19:49:59 <AchiestDragon> yes
Feb 01 19:50:23 <ka6sox-office> (flex in the board is minimal)
Feb 01 19:51:11 <fishhead> sorry about the popup folks, apprentely that site is a fake copy of the good site that was a url of jumpers for 1000's of computer parts
Feb 01 19:52:02 <AchiestDragon> fishhead:  can you find one with the verious jtag pinouts listed
Feb 01 19:52:41 <fishhead> http://www.osuweb.net/~ahaning/totalhardware99/ <--- here is the right site including a complete zip file torrent! woop!
Feb 01 19:52:50 <fishhead> mabye someday :)
Feb 01 19:59:42 * fishhead goodnight all, switching to bedroom pc, might be back, mabye not
Feb 01 21:53:28 <velinp> ~seen ka6sox-office
Feb 01 21:53:37 <purl> ka6sox-office is currently on #openjtag (2h 27m 33s). Has said a total of 4 messages. Is idling for 2h 3m 14s, last said: '(flex in the board is minimal)'.
Feb 01 23:32:58 <beewoolie> ka6sox: hi
Feb 01 23:33:06 <beewoolie> Kinda quiet tonight.
Feb 01 23:47:30 <ka6sox> ya
Feb 01 23:47:49 <ka6sox> glad to finally be home.
Feb 01 23:54:25 <beewoolie> I learned something interesting a couple of days ago.
Feb 01 23:54:46 <beewoolie> Someone gave me a couple of 5 port hubs because he didn't have the power supplies.
Feb 01 23:55:00 <beewoolie> I opened them up to examine the circuit.
Feb 01 23:55:13 <beewoolie> I wired them so that I could apply power from a bench PS I have.
Feb 01 23:55:36 <beewoolie> The hubs start operating at about 3.5V, but the LEDs peak their brightness at 7v.
Feb 01 23:55:59 <beewoolie> Turns out that these hubs use a DC to DC converter and can accept any DC voltage up to about 40V.
Feb 01 23:57:07 <beewoolie> So, all I need to do is find a wall wart that has the right size plug.
Feb 02 00:01:22 <beewoolie> ka6sox: It's kinda late to be just getting in.
Feb 02 00:03:01 <ka6sox> no kidding!
Feb 02 00:03:41 <ka6sox> I've been out all day in fire fighting mode...I hope tommorrow is sane.
Feb 02 00:03:59 <ka6sox> those hubs sound like a good deal :)
Feb 02 00:04:04 <ka6sox> who makes em?
Feb 02 00:29:58 <beewoolie> These are linksys jobbers.
Feb 02 00:30:27 <beewoolie> 5 port.  No switches, there is a plug for mdix to support uplinking.  All of the new gear auto-detects.
Feb 02 00:30:39 <beewoolie> Still, I like having some small stuff like this for testing.
Feb 02 00:34:08 <ka6sox> that is always good to have around.
Feb 02 00:56:35 <beewoolie> w00t!  I've got the boundary scan reading from flash.
Feb 02 00:57:14 <ka6sox> which board?
Feb 02 00:57:58 <beewoolie> This is with one of the ARM9 targets.
Feb 02 00:58:22 <beewoolie> This should work on the Xscale as well since it doesn't use the CPU to perform the read.
Feb 02 00:58:41 <beewoolie> It won't be fast, but it is an important step in performing the boundary scan.
Feb 02 00:58:50 <ka6sox> indeed
Feb 02 01:48:47 <beewoolie> later.
Feb 02 02:50:48 <AchiestDragon> hmmm , ok so we got a 20pin arm jtag port ,  but what about this ?    http://www.interfacebus.com/Design_Connector_JTAG_Bus.html
Feb 02 02:54:46 <vmaster> not sure who uses this
Feb 02 02:55:53 <AchiestDragon> no me nether , just think its funny having a industry standard that everyone has a diferent style anyway 
Feb 02 02:56:12 <vmaster> the standard doesn't define a connector
Feb 02 02:56:42 <vmaster> and there are so many uses of jtag, a single connector could hardly fit them all
Feb 02 02:57:35 <AchiestDragon> well we got support for 3 so far 
Feb 02 02:58:20 <vmaster> arm20, arm14 and digilent?
