Aug 26 03:00:19 <necronian> I have read the instructions a few times, there are only 94 lines in the readme file :-p
Aug 26 03:14:15 <tinker-f595> well you missed something
Aug 26 03:39:27 <tinker-f595> necronian: http://www.plugcomputer.org/plugwiki/index.php/SheevaPlug_Installer
Aug 26 03:50:57 <necronian> yea, I read all that. I wouldn't even say my problem is with the sheevaplug installer
Aug 26 03:51:40 <necronian> it's with openocd not being able to flash uboot and uboot-env
Aug 26 03:53:41 <tinker-f595> hmmmm and you have usbTTY0 and usbTTY1 active on the host machine ?
Aug 26 03:54:09 <tinker-f595> and the  cable is plugged in securely into the sheevaplug
Aug 26 03:54:31 <necronian> no I just have a usbTTY0, since about a month ago when I updated my kernel
Aug 26 03:54:47 <tinker-f595> wrong!!!
Aug 26 03:55:23 <tinker-f595> unload the module and then load it again
Aug 26 03:56:29 <tinker-f595> necronian: http://plugcomputer.org/plugforum/index.php?topic=2.0
Aug 26 03:57:00 <necronian> I think that it's udev doing it, it ignors the jtag interface and puts the serial console on ttyusb0
Aug 26 03:58:44 <tinker-f595> hmmmm what did you do?
Aug 26 03:59:07 <tinker-f595> you should have 2
Aug 26 04:01:06 <tinker-f595>   "/dev/ttyUSB0"  and "/dev/ttyUSB1"
Aug 26 04:01:56 <necronian> I don't think that's the problem because of this http://plugcomputer.org/plugforum/index.php?topic=501.0
Aug 26 04:02:01 <tinker-f595> do a rmmod ftdi_sio
Aug 26 04:02:20 <tinker-f595> and then modprobe blah blah
Aug 26 04:03:01 <tinker-f595> see http://www.openplug.org/plugwiki/index.php/Serial_terminal_program#Getting_the_USB_serial_device_working
Aug 26 04:03:18 <necronian> but if nothing else works maybe I'll track down a livecd to boot off and see if that works
Aug 26 04:04:49 <tinker-f595> hmmmm I am using the latest kernel on my desktop and all is fine
Aug 26 04:06:34 <necronian> Well I don't know if it was the kernel update or something else that got updated
Aug 26 04:06:59 <tinker-f595> which distro and kernel?
Aug 26 04:07:40 <necronian> archlinux 2.6.30.4
Aug 26 04:08:07 <tinker-f595> hmmmm
Aug 26 04:08:33 <necronian> it was never a problem before, I just said that's weird and pointed minicom at ttyUSB0 instead
Aug 26 04:08:39 <tinker-f595> well you have the source....did you check the config file?
Aug 26 04:09:39 <necronian> no, well I know that the ftdi driver is working fine
Aug 26 04:10:40 <necronian> because I was using the serial console and broke into uboot right before I tried running the sheevaplug installer
Aug 26 04:10:43 <tinker-f595> might have something commented out that should not be
Aug 26 04:11:13 <tinker-f595> my understanding the jtag is on the other port
Aug 26 04:11:21 <tinker-f595> getting tired...
Aug 26 04:13:03 <necronian> well thanks for the help anyway
Aug 26 04:14:12 <tinker-f595> he first serial device ("/dev/ttyUSB0"  is supposed to be the JTAG interface; the second serial device  ("/dev/ttyUSB1) is supposed to be the serial console. well good luck...when you solve the mystery you should update http://www.openplug.org/plugwiki/index.php/Serial_terminal_program#Getting_the_USB_serial_device_working
Aug 26 04:18:02 <tinker-f595> necronian: I did this on my desktop http://www.openplug.org/plugwiki/index.php/Load_Serial_Drivers_Automatically_Using_udev
Aug 26 04:21:55 <necronian> I'm probably just going to throw ubuntu or something on another partition, something more mainstream and less bleeding edge
Aug 26 04:23:22 <tinker-f595> yeah well ubuntu tneds to be trailing edge
Aug 26 04:23:27 <tinker-f595> tends
Aug 26 04:24:24 <necronian> exactly, I'll have an older kernel and I wont need to start messing around with anything on my archlinux install
Aug 26 04:24:41 <necronian> I just got it set up perfectly the way I want it
Aug 26 04:26:29 <tinker-f595> I am using 2.6.29.6
Aug 26 04:26:55 <tinker-f595> which is from a few days ago with the null handling fix
Aug 26 07:59:40 <echosystm> how would a usb flash drive go for downloading torrents?
Aug 26 08:00:07 <echosystm> one of the 16/32gb ones would suffice in size, im just wondering how quickly the memory will go bad
Aug 26 13:00:45 <echosystm> guys ive just found some conflicting results
Aug 26 13:01:06 <echosystm> http://computingplugs.com/index.php/SheevaPlug_Performance
Aug 26 13:01:13 <echosystm> this page shows very poor samba performance
Aug 26 13:01:33 <echosystm> but ive seen people in the forums claiming 25-30MBps
Aug 26 13:01:42 <yacoob> ymmv :)
Aug 26 13:01:58 <echosystm> more than twice as much?
Aug 26 13:02:00 <echosystm> lol
Aug 26 13:02:01 <yacoob> more seriously though, test along the lines of "I copied a file and got this number" is useless
Aug 26 13:02:29 <yacoob> echosystm, what if one person was using 100Mbps ethernet, and the other 1000Mbps one?
Aug 26 13:02:57 <echosystm> if you look on the benchmark page you'll see he's using gb ethernet
Aug 26 13:03:09 <yacoob> bummer
Aug 26 13:03:19 <echosystm> im not sure who to beleive
Aug 26 13:03:28 <echosystm> but im leaning towards the forum users
Aug 26 13:03:34 <yacoob> you'd have to test it yourself
Aug 26 13:03:50 <echosystm> well, i dont want to buy one if its not going to work well haha
Aug 26 13:04:37 <yacoob> :)
Aug 26 13:04:57 <echosystm> that's kind of the reason im looking at these benchmarks in the first place
Aug 26 13:08:04 <ukki> are there any howtos about possible gcc optimizations?
Aug 26 13:08:46 <ukki> i would love to get it to transcode properly, but am i asking too much?
Aug 26 13:09:09 <yacoob> this marvel chip doesn't have fpu, does it?
Aug 26 13:09:17 <ukki> got vdr working yesterday btw, that was my main goal so i'm happy
Aug 26 13:09:20 <ukki> yeah :(
Aug 26 13:09:40 <ukki> i only read about it after i ordered
Aug 26 13:10:00 <ukki> i guess it would have helped a lot
Aug 26 13:10:16 <yacoob> usb-based fpga array... :)
Aug 26 13:12:07 <ukki> but there must be some gcc switches i could try
Aug 26 13:12:18 <ukki> it wasn't totally hopeless
Aug 26 13:13:54 <ukki> and vlc seems to be little heavier than other solutions
Aug 26 14:30:03 <ShadowJK> audio transcoding would suffer from the lack of fpu
Aug 26 14:30:22 <ShadowJK> but video transcoding doesn't use much floating point
Aug 26 14:35:49 <e`> ukki, gcc -O2 and -O3 are supposed to mean "enable optimizations that give you best average speedup".
Aug 26 14:36:36 <e`> you can eke out marginally more performance by experimenting with the detailed knobs but that won't make your sheevaplug a video transcoding monster
Aug 26 14:37:11 <e`> acovea can automate the knob finding
Aug 26 14:37:26 <ShadowJK> I'd set my expectations somewhere near the performance of a 300MHz Pentium2 :-)
Aug 26 14:38:06 <ShadowJK> (P2 has ooo execution and MMX, giving it much better performance per clock)
Aug 26 14:39:59 <e`> the kirkwood core is actually ooo
Aug 26 14:54:23 <ShadowJK> ah, didn't know that
Aug 26 15:09:15 <rabeeh> ShadowJK: can you run a test and provide numbers?
Aug 26 15:09:39 <rabeeh> ShadowJK: I hate to see people giving random numbers without backing them up with lab benchmarks
Aug 26 15:12:49 <e`> http://www.linleygroup.com/pdf/WP_MRVL.pdf seems to have slightly more tidbits on the microarchitecture than the marvell pr stuff
Aug 26 15:15:44 <e`> the armv5te instruction set seems to include some codec acceleration instructions like saturating arithmetic .. no simd though
Aug 26 15:46:23 <tinker-f595> Why don't you look at the Kirkwood functional specs?
Aug 26 15:48:58 <e`> i don't remember it having any implementation details, just stuff on how to program it
Aug 26 15:49:54 <e`> i'll have another look.
Aug 26 15:50:38 <e`> it only has this on the core
Aug 26 15:50:44 <e`> For full details and specifications about the Sheeva CPU core refer to the following documents: SheevaTM 88SV131 ARM v5TE Processor Core with MMU and L1/L2 Cache Datasheet (Doc No. MV-S104950-00)
Aug 26 15:50:53 <e`> but that's apparently a secret document
Aug 26 15:54:19 <tinker-f595> sounds like you did not read the document
Aug 26 15:55:03 <e`> well, it's 700+ pages, pointers gladly accepted :)
Aug 26 15:55:23 <e`> http://www.mail-archive.com/linux-crypto@vger.kernel.org/msg03695.html <- seems crypto engine support is coming along
Aug 26 15:56:50 <tinker-f595> Now these look interesting as they have VFP http://www.marvell.com/products/communication/discovery_innovation/index.jsp
Aug 26 15:57:50 <e`> searching through the functional spec for uarch terms like "branch prediction" doesn't yield anything either (besides the pr summary and reference to the secret document)
Aug 26 16:01:01 <tinker-f595> your assuming it is fully indexed
Aug 26 16:01:33 <tinker-f595> http://www.marvell.com/products/embedded_processors/kirkwood/index.jsp
Aug 26 16:05:21 <tinker-f595> hmmm
Aug 26 17:40:04 <Xion345> Hello
Aug 26 17:55:43 <Q_Continuum> hi
Aug 26 22:56:51 <Xion345> Hello again
Aug 26 22:57:53 <Xion345> I would like to know if someone has got unionfs/aufs or mini_fo running under debian (armel/kirkwood) ?
Aug 27 02:10:21 <echosystm> would a usb hard drive use significantly more cpu than sata?
Aug 27 02:10:55 <echosystm> ie. could i get better samba performance with an openrd (sata) ?
