  • [00:08:34] <regomodo> ah ok
  • [00:08:46] <mru> so you need to get -lrt into the linker flags somehow

  • [00:22:55] <regomodo> My PC regularly locks up on big loads.
  • [00:23:04] <spikebike> mru: I disagree, seems like often a linux desktop gets laggy with make -j, or running any number of things that keep all cores busy
  • [00:23:18] <spikebike> like say video transcoding

  • [00:27:05] <spikebike> try playing 3d games while compiling on all cores
  • [00:27:14] <mru> of course if you care about interactive respone you should use a preemptible kernel
  • [00:27:33] <mru> spikebike: at some point you run out of cpu cycles
  • [00:27:36] <spikebike> well sure, but I'd prefer to use the mainline kernel
  • [00:27:47] <spikebike> well there's cycles aplenty, it's just spending them in the wrong place
  • [00:27:48] <mru> then you adjust nice levels so the important things get enough time
  • [00:27:59] <mru> the kernel can't know which ones you consider important
  • [00:28:18] <mru> spikebike: it is the mainline kernel, just a config option
  • [00:28:19] <spikebike> well often I can watch a movie
  • [00:28:30] <spikebike> but then I switch desktops and it really lags
  • [00:28:39] <spikebike> and things like moving windows is slow
  • [00:28:55] <mru> if switching desktops lags, you don't have enough ram
  • [00:29:13] <spikebike> ya, sometimes
  • [00:29:16] <mru> get 8GB minimum and turn off swap
  • [00:29:21] <spikebike> I have 8gb ;-)
  • [00:29:24] <spikebike> I do use swap though
  • [00:29:32] <mru> turn it off
  • [00:29:39] <mru> just as a test
  • [00:29:48] <spikebike> I suspect that the patch will make it nicer to use under load, as would either swap off, swap on ssd, and/or home on ssd
  • [00:30:28] <spikebike> I'll have to pay more attention during lag
  • [00:30:31] <mru> although if you have swap on and it actually gets used, you have too little ram
  • [00:30:43] <CodingFusion> Where would you suggest getting a high performance workspace computer?
  • [00:30:56] <spikebike> "workspace"?
  • [00:30:57] <mru> from your favourite computer parts vendor
  • [00:31:02] <CodingFusion> Desktop
  • [00:32:00] <CodingFusion> haha, I'd still like someones suggestions and opinions before I spend my money. I do my research but peoples opinions do help.
  • [00:32:13] <mru> for a new high performance machine I suppose a sandy bridge cpu, 16GB or more fast ram, and a matching motherboard should do the trick
  • [00:32:32] <spikebike> I've got a lynnfield quad core (8 thread) desktop with 8GB ram and it certainly seems to occasionally have poor interactive performance without significant IO/swap, but I'll have to look close
  • [00:32:54] <spikebike> ya, sandy bridge = kick ass. I'd wait for the xeon version (not out yet) if you want ecc
  • [00:33:13] <mru> I'm running an i7 940
  • [00:33:21] <mru> had it a couple of years
  • [00:33:28] <mru> still feels fast
  • [00:33:37] <spikebike> mine is the 2.66 GHz equiv of the desktop i7 umm 860 I think
  • [00:33:42] <spikebike> (2 memory busses not 3)
  • [00:33:52] <spikebike> except the xeon version has HT and the desktop version doesn't
  • [00:34:01] <mru> mine has ht and triple-channel ram
  • [00:34:12] <spikebike> ya, nice chip
  • [00:34:40] <spikebike> sandy bridge with ecc, 8 threads, and minimum GHz around 3.1 GHz should be awesome
  • [00:34:52] <CodingFusion> Just about to get paid off from my recent project, planning to spend it on a nice computer.
  • [00:35:05] * Ceriand|desktop (~Ceriand@unaffiliated/ceriand) has joined #beagle
  • [00:35:20] <spikebike> If you want a somewhat more reliable computer I'd pay for the xeon version
  • [00:35:24] <CodingFusion> Thats why I asked. Alright Sany bridge with a ton of ram XD
  • [00:35:26] <spikebike> approximately $0 for the xeon cpu
  • [00:35:34] <spikebike> but another $50-$100 for motherboard and ram
  • [00:35:47] <mru> I usually get the second chip from the top
  • [00:35:56] <mru> the top one is always stupidly overpriced
  • [00:36:03] <spikebike> I usually get the slowest chip that's not crippled
  • [00:36:10] <spikebike> usually $230-$250 ish
  • [00:36:52] <mru> by aiming high I get something that lasts a while
  • [00:36:52] <CodingFusion> Money isn't really an option here, as long is works for a good LONG time.
  • [00:37:12] <mru> $1k isn't that much if spread over a few years
  • [00:37:42] <mru> and I'm still using the core2 I used before this one for experiments
  • [00:38:19] <CodingFusion> Exactly, its an investment. A $5k computer for 10 years without the need of a whole system upgrade would be a great investment.
  • [00:38:26] <CodingFusion> However I only picture 5 years.
  • [00:38:31] <CodingFusion> At the most.
  • [00:38:34] <mru> I gave up on incremental upgrades
  • [00:38:47] <aholler> you don't need to use make -j6 or such to reach a situation where that cgroup-patch helps
  • [00:38:51] <mru> that worked when cpus and ram used the same sockets for 2 or 3 generations
  • [00:38:55] <mru> that's not the case anymore
  • [00:39:01] <spikebike> mru: heh, the 2nd from top vs minimum usually is a 20% best case performance improvement and a 0% worst case improvement
  • [00:39:01] <CodingFusion> I might do that with RAM and graphics Maybe.
  • [00:40:10] <mru> spikebike: what do you mean by best vs worst case?
  • [00:40:17] <mru> 4 cores is twice as much as 2 cores
  • [00:40:29] <spikebike> ya, I usually get the slowest quad
  • [00:40:50] <spikebike> q6600, i7-860, e3-1230
  • [00:41:03] <spikebike> sure I could have spend twice as much on each cpu but with little real world performance increase
  • [00:41:30] <spikebike> with CPUs $600 vs $250 usually gets you about zilch
  • [00:41:45] <mru> I like being able to rebuild gcc in a few minutes
  • [00:41:54] <spikebike> ya, same here
  • [00:41:59] <mru> or other big things
  • [00:42:29] <spikebike> the 10-20% clock speed increase just doesn't make a noticeable difference in most cases unless you get out a stopwatch
  • [00:42:32] <CodingFusion> Full kernels would be awesome for my next project.
  • [00:42:58] <mru> if you're rebuilding gcc frequently you'll notice
  • [00:43:09] <spikebike> so for the next gen you'd get the E3-1270?
  • [00:43:20] <mru> no idea yet
  • [00:43:41] <spikebike> e3-1270 = 3.4 GHz for $350
  • [00:43:44] <mru> I'll get something new when this one starts feeling slow
  • [00:44:01] <CodingFusion> 1 minute difference in compiling could be one more minute doing something else.
  • [00:44:15] <aholler> get an ssd, that will help more than any cpu
  • [00:44:24] <spikebike> e3-1230 3.2 GHz for $220-$240
  • [00:44:25] <mru> not here
  • [00:44:27] <mru> I build in tmpfs

  • [00:44:45] <spikebike> aholler: dunno, with enough ram gcc builds seem mostly CPU bound
  • [00:44:51] <aholler> and how do the tmpfs get his files?
  • [00:44:52] <spikebike> i.e. scales well with -j 8
  • [00:45:30] <CodingFusion> I was looking at some desktops, dual 3.60Ghz processors would last me a very long time.
  • [00:45:31] <mru> aholler: if it's something I'm working actively on, from in-memory cache
  • [00:45:42] <CodingFusion> (if it didn't fry or something else stupid)

  • [00:46:30] <mru> managed to repair it though
  • [00:46:32] <spikebike> CodingFusion: ya I looked at that but the cost is substantial, and it's much harder to keep quiet
  • [00:46:47] <aholler> hmm, maybe the musb-driver is already build by that driver-maker-stuff from that certain company ;)
  • [00:46:50] <spikebike> seems like you are better off getting a single socket every 2 years than a dual socket every 4... and still end up cheaper

  • [00:49:05] <spikebike> and if it's fanless and your other fan dies poof goes your system and/or ps
  • [00:49:19] <mru> there's a 250mm fan in the side of the case
  • [00:49:48] <spikebike> yeah, tempted by the 250s, but they seem more poorly made than the nice 120mm fans
  • [00:50:01] <spikebike> so currently I use 2 ish quality 120mm fans that are thermo regulated
  • [00:50:10] <spikebike> which means that my system is almost always silent

  • [00:52:18] <aholler> i never heard the psu (with fan) of my watercooled system
  • [00:52:59] <spikebike> ya, as long as your case has decent airflow and your PSU fan is temperature based and of decent quality you should never hear it

  • [00:56:35] <spikebike> and $500 less than a top spec system with a top bin cpu and water cooling
  • [00:57:23] <aholler> but water could be dangerous too: http://ahsoftware.de/schmorrplatte.jpg
  • [00:58:04] <spikebike> ya water cooling seems a bit much for the win
  • [00:58:16] <spikebike> sure a 3.4 Ghz cpu could be as quiet as a 3.1 GHz cpu
  • [00:58:35] <mru> aholler: what happened there?
  • [00:58:39] <spikebike> but considering that the price usually means you buy less often, so you end up drifting further from the state of the art
  • [00:59:07] <spikebike> my "slow" lynnfield was much faster than the previous generation top bin chip
  • [00:59:17] <spikebike> I think sandy bridge manages that as well
  • [00:59:28] <aholler> mru: a bit water run down the cable. the rest of the computer hasn't noticed it, all runned normal, except that hd

  • [01:01:20] <spikebike> heh
  • [01:01:23] <aholler> it was deionized, but I had a bit too much force on the hd-water-connector
  • [01:01:49] <aholler> (look at that wakue1.jpg)

  • [01:02:54] <spikebike> so you need "high performance" thermal goop, and "high performance water additives", heat sinks with fancy designs to look cool, dimms with heat generating leds on them, etc.
  • [01:03:36] <aholler> the problem with watercooling is that you need new stuff for every processor or graphic card
  • [01:03:47] <spikebike> fortunately that means the ones that look ugly, no lights, simple design are often dirt cheap ;-)
  • [01:04:09] <mru> aholler: they make quite a few multi-socket cpu blocks

  • [01:10:22] <spikebike> well the Antec P180 and it's derivatives are similar in design, and rather quiet
  • [01:10:25] <mru> can it be modified in some way?
  • [01:10:34] <spikebike> the apple can't
  • [01:10:44] <spikebike> it's got a hugely complex sensor/control system that freaks if you change it

  • [01:11:23] <mru> had to build a little adaptor circuit to keep the system happy
  • [01:11:29] <spikebike> but the antec is similar, has a seperate airflow for drives+power supply
  • [01:11:39] <spikebike> nice front-back airflow with only 120mm fans
  • [01:11:55] <mru> so the mac can't be fitted with a less noisy fan at all?
  • [01:11:56] <spikebike> and you can hide the cables behind the motherboard for a nice clean build that doesn't clock airflow
  • [01:12:09] <spikebike> oh, as long as they are similar in spec it should be fine
  • [01:12:28] <spikebike> just can't change RPM, static pressure, number of fans, etc much
  • [01:12:39] <mru> rpm can be faked
  • [01:12:49] <spikebike> pure AL for a case seems to be a loss because of its resonance
  • [01:13:09] <spikebike> well sure, but it's an active system and can freak if the RPMs don't change as expected
  • [01:13:26] <mru> hrmph

  • [01:18:35] <mru> the sooner you order, the sooner you receive
  • [01:18:50] <spikebike> well at 8 weeks seems like something might well come out better before delivery
  • [01:18:59] <tdh2002> can some tell me the voltage of mmc card on beagleboard ?
  • [01:19:12] <spikebike> seems like dual core arms are starting to flood from all involved parties
  • [01:19:14] <aholler> the panda is missing a rtc and normal network
  • [01:19:22] <mru> aholler: define normal
  • [01:19:28] <aholler> not usb
  • [01:19:29] <spikebike> wow, rtc, really?
  • [01:19:43] <mru> it doesn't have battery-backed rtc
  • [01:19:49] <mru> not needed for a dev board
  • [01:20:01] <spikebike> oh, not sure I care, I assume network, which means ntp
  • [01:20:02] <aholler> which is imho wrong ;)
  • [01:20:30] <spikebike> not having GigE is kinda frustrating
  • [01:20:39] <spikebike> the "Onboard 10/100 Ethernet" is usb connected?
  • [01:20:45] <spikebike> (on pandaboard)
  • [01:20:47] <mru> phones don't need GbE
  • [01:20:51] <aholler> especially as a dev-board you want have to depend on network ;)
  • [01:21:21] <spikebike> phones don't need 1GB either, or HDMI out, or dvdid out
  • [01:21:35] <ds2> HiDef phones?
  • [01:22:02] <spikebike> seems like pandaboard would be useful for many non-phone projects. Home automation, security, settop box, NAS appliance, etc.
  • [01:22:15] <mru> it's a mobile chip, deal with it
  • [01:22:26] <mru> there are other chips with GbE etc
  • [01:22:47] <spikebike> I can live with 100 mbit
  • [01:22:55] <spikebike> it's just on my wish list
  • [01:22:57] <mru> well, that you get over usb
  • [01:23:22] <aholler> if there are no problems with the usb-driver ;)
  • [01:24:09] <spikebike> I want to avoid cross compiling, and run a relatively sane distro (i.e. with apt-get). Enough cpu for handling a usb-cam or two and doing motion detection
  • [01:24:35] <mru> why are people so afraid of cross-compiling?

  • [01:24:52] <spikebike> so dual core, 512-1024GB ram, and lan
  • [01:24:57] <spikebike> it's a pain
  • [01:25:03] <CodingFusion> mru, its annoying
  • [01:25:15] <spikebike> say I want to write a code that send me a message when the mailman comes
  • [01:25:21] <mru> CodingFusion: I don't think so
  • [01:25:24] <mru> waiting is annoying
  • [01:25:30] <spikebike> it would be nice to write in python, but I'll need some modules to send XMPP messages
  • [01:25:41] <aholler> just trying to cross-compile perl is a pain
  • [01:25:51] <mru> perl is evil, yes
  • [01:25:51] <CodingFusion> mru, so true, I've been waiting for ROS to stop compiling for like.. 2 hours now
  • [01:25:54] <spikebike> So I want a package manager, and a main line distro
  • [01:26:10] <mru> sounds like you want a PC
  • [01:26:38] <aholler> or gentoo
  • [01:26:40] <spikebike> not some embedded piece of crap where it's labor intensive to get every image processing/network protocol/compression/encryption routine
  • [01:27:00] <mru> why don't you buy a PC then?
  • [01:27:02] <spikebike> nah, arm's got plenty of resources, ram, storage
  • [01:27:12] <CodingFusion> Spikebike for the mail man problem, just have a magnet alarm that sends the singal to arduino -> xbee :P
  • [01:27:20] <spikebike> I used to run a large department on a dual core machine with 1/2 the ram of the pandaboard
  • [01:27:52] <mru> yes, and once upon a time my main computer ran at 233MHz with 128MB RAM
  • [01:27:58] <spikebike> mru: small size and small power usage would be ideal
  • [01:28:01] <mru> because that was the best I could get at the time
  • [01:28:13] <spikebike> ya, I started out on a 286-6 Mhz
  • [01:28:19] <mru> now I can get a crazy fast i7 for big jobs
  • [01:28:20] <spikebike> but my first linux box was a 386sx-16
  • [01:28:38] <mru> oh, I had a 286 12MHz too
  • [01:28:43] <mru> whopping 640k RAM
  • [01:28:51] <mru> and a 40MB hd
  • [01:28:56] <mru> good stuff
  • [01:28:57] <spikebike> well I used a imsai 8080, tektronix 4051, and a pdp-11/02 before that
  • [01:28:58] <mru> in the 80s
  • [01:29:04] <aholler> i had an 8088, amiga side-car, starting nc needed minutes ;)
  • [01:29:04] <spikebike> but none ran linux
  • [01:29:11] * BT (c07a8314@gateway/web/freenode/ip.192.122.131.20) has joined #beagle
  • [01:29:16] <CodingFusion> I think I'll custom build this time, http://www.newegg.com/Product/Product.aspx?Item=N82E16819115079 for the processor.
  • [01:29:20] <spikebike> but I also ran 100 diskless terminals, webserver, and mailserver off a p3-500 with 512MB ram
  • [01:29:27] <mru> of course you did
  • [01:29:31] <mru> that's not the point
  • [01:29:41] <mru> the point is it's stupid not to use the best that's available
  • [01:29:47] <spikebike> there's no reason for a beagle board/pandaboard not to run a "real" linux environment that will minimize the number of man hours to make it into something useful for home automation
  • [01:30:00] <mru> for compiling stuff, your workstating, whatever it is, is faster than some little embedded board
  • [01:30:17] <spikebike> ya, but apt-get python-xmpp = saves me hours of futching
  • [01:30:29] <spikebike> many more hourse than it will take compiling whatever small code I need to compile
  • [01:30:35] <CodingFusion> haha spikebike try rootstock.
  • [01:30:55] <aholler> or debian/ubuntu, both are available for arm too
  • [01:31:05] <spikebike> so I dislike most embedded linux's of the no package management variety that tend to get used then reinstalled
  • [01:31:14] <spikebike> ya, debian, ubuntu, gentoo, etc is fine
  • [01:31:25] <CodingFusion> rootstock will install all the needed packages that you need for you project into a rootfs you can use on a embedded microcomputers
  • [01:31:41] <spikebike> CodingFusion: sounds cool
  • [01:31:57] <CodingFusion> I used it so I could save 2 hours on a compiling process on the beagle.
  • [01:32:26] <spikebike> ya, if I needed to ever wait even 10 minutes for a compile I'd probably cross compile
  • [01:32:36] <spikebike> I suspect anything I write would be on the order of seconds
  • [01:32:47] <CodingFusion> well I"m up to.. 2 hours on it already.
  • [01:32:47] <aholler> why? you don't need to look at
  • [01:33:11] <CodingFusion> 2 hours and 1/2 sorry.
  • [01:33:48] <spikebike> speaking of which, is beagle planning on going dual core anytime soon?
  • [01:34:00] <spikebike> or is that going to just be panda?
  • [01:34:26] <BT> Hey can someone tell me what is wrong when I get this error 'init: /init.rc: 171: invalid option 'root''? The line in init is 'mkdir /data/misc/wifi/sockets 0770 wifi wifi'
  • [01:34:29] <CodingFusion> When is the panda?

  • [01:35:20] <CodingFusion> Guess, I'll have to buy one then.
  • [01:35:30] <mru> pandaboard has been shipping since october or november
  • [01:35:45] <CodingFusion> Didn't notice I guess.
  • [01:37:48] <spikebike> they have had a back order on the order of 1000-1500 for awhile and 8 week delivery times or so
  • [01:37:49] <djlewis> SPow: did you come up with a uart2 level /serial driver ic?
  • [01:38:01] <spikebike> but I heard they delivered 500 monday ish and were planning on another 500 friday ish
  • [01:38:08] <spikebike> so hopefully they time will shrink
  • [01:38:41] <SPow> djlewis: what ?
  • [01:39:02] <djlewis> SPow: what are you connecting to your uart2?
  • [01:39:21] <djlewis> did you get the noise fixed?
  • [01:39:27] <SPow> either a zigbee module or a microcontroller
  • [01:39:28] <CodingFusion> OH shi... I forgot 10 packages..
  • [01:39:37] <SPow> yeah it works fine now ^^
  • [01:39:43] <CodingFusion> I hate apt-get on this dang beagleboard
  • [01:40:02] <djlewis> SPow: cool. I am playing irc catch up.
  • [01:40:02] <SPow> need to find commands I can use in a script now
  • [01:40:06] <SPow> hehe
  • [01:40:31] <SPow> but that's for thursday, I have another project i'm finishing now
  • [01:40:44] <djlewis> SPow: sakoman enabled uart2
  • [01:40:51] <SPow> ooh ?
  • [01:40:52] <djlewis> i expect you know
  • [01:40:54] <CodingFusion> Why does compiling ROS have to be such a pain!?
  • [01:41:07] <SPow> nope, just did RX and prepared to rebuild
  • [01:41:17] <SPow> did he include it in his last build ?
  • [01:41:23] <djlewis> yes
  • [01:41:33] <SPow> so just need to rerun his script ?
  • [01:41:37] <djlewis> actually as of last week
  • [01:41:47] <djlewis> should do it
  • [01:42:02] <SPow> great news :D
  • [01:42:08] <djlewis> pull out your spare SD
  • [01:42:19] <SPow> could you make use of it ?
  • [01:42:28] <djlewis> uart2?
  • [01:42:35] <SPow> cuz you were thinking of rebuilding as well no ?
  • [01:43:01] <djlewis> no, i dont rebuild kernels, I let kernel people do that

  • [01:44:12] <SPow> well, thanks for the tip, going back to bed since it's like 2:44 here ^^
  • [01:44:33] <djlewis> SPow: i use uart2 to talk to the avr on the trainer board

  • [06:43:17] <linux_manju> I have a Beagleboard XM REV2 board, When I connect my BB to my LCD tv via HDMI Nothing comes on the screen, Could some one confirm if I use HDMI to VGA converter and connect it to Monitor/TV will it work ?

  • [06:45:40] <NotTooDumb3> linux_manju, i think hdmi should work..
  • [06:45:54] <aholler_> linux_manju: ask google how to set the frequency and resolution for a beagleboard. no edid there
  • [06:46:18] * aholler_ is now known as aholler
  • [06:46:45] <linux_manju> aholler_: I tried everything.. Looks like As my TV does not support Full HD .. Its not working ( Not sure if thats the reason )
  • [06:47:15] <linux_manju> aholler: I tried all combination.. It never worked for me :( ( Tried for almost 6 Months sofar )
  • [06:47:44] <linux_manju> aholler: As a final resort, Planning to go with HDMI to VGA converter.. Just wanted to check If it would work
  • [06:48:07] <aholler> no
  • [06:48:19] <linux_manju> no==Will not work ?
  • [06:48:55] <aholler> yes, you would need an active converter which isn't cheap. find the real reason.
  • [06:49:30] <linux_manju> aholler: Sorry.. I am not too good with Electronics.. Can you please explain.. whats an active converter.. In other words..
  • [06:49:51] <linux_manju> If I use.. HDMI to VGA converter supplied by Apple .. will it work
  • [06:49:59] <linux_manju> They are not cheap by the way :P
  • [06:50:11] <lucky___> I have a query . would some one like to help me! I had successfully got the output of my beagle on my laptop tv tunner, by upconverting the s-vdo/rca to rf.

  • [06:50:35] <aholler> lucky___: repeating your question will not give faster answers
  • [06:51:47] <linux_manju> lucky___: Why not try linaro Netobook image .. it comes with X by default
  • [06:52:00] * linux_manju netobook=-netbook
  • [06:52:00] <aholler> linux_manju: the bb doesn't offer analog signals, and because you don't know your problem, it's unlikely that an converter will help

  • [06:54:13] <linux_manju> aholler: Like.. Beagle board HDMI I will use DVI converter and then DVI to VGA converter .. will that work
  • [06:54:22] <NotTooDumb3> linux_manju, what you have on bb is DVI and not HDMI right?
  • [06:54:54] <linux_manju> NotTooDumb3: Both DVI and HDMI signals are same.. DVI is basically HDMI without Audio
  • [06:55:23] <aholler> so why you think a converter will help?
  • [06:55:26] <linux_manju> NotTooDumb3: On a lucky day.. with a compatible TV/Monitor.. Direct HDMI cable from BB to TV/Monitor works out of the box
  • [06:55:42] <NotTooDumb3> oh..ok.i felt i remember someone saying they used DVI to HDMI converter and made it to work..not sure i am correct though

  • [06:56:37] <NotTooDumb3> linux_manju, i think others were using HDMI on bb, dont know how though
  • [06:57:35] <linux_manju> aholler: If the TV does not support Full HD.. Do you think.. HDMI connection still works?. Because.. For me Nothing is on the screen.. its frustrating :(
  • [06:57:53] <aholler> you can change the resolution
  • [06:58:03] <aholler> to whatever your tv understands
  • [06:58:30] <linux_manju> aholler: I tried all possible Resolutions and Frequency .. told you it went on for 6 Full months :)
  • [06:58:50] <aholler> than why you are talking about full hd=
  • [06:58:55] <aholler> ?
  • [06:59:25] <linux_manju> aholler: I *THOUGHT* that could be the reason
  • [06:59:55] <linux_manju> aholler: If I send u my TV Manual.. Can you please help.. I know I am asking for too much.. But.. *sigh*
  • [07:00:23] <aholler> no. sorry.
  • [07:00:45] <linux_manju> aholler: NP.. But thanks for trying anyway :)

  • [07:02:07] <aholler> test with the latest u-boot/xloader(mlo) kernel from the validation image, maybe that helps. I've seen somewhere that the dvi-power has changed for the xm and the necessary patch might have come in later.
  • [07:02:34] <aholler> (has changed = is different than for the bb)
  • [07:03:43] <linux_manju> aholler: Yes.. I know that Actually, I was one of the first person to raise a bug on No DVI output.. But with the patch also.. it did not work for me :(

  • [07:04:37] <linux_manju> aholler: Just one small question.. which version of BB do you use and what OS and monitor ?
  • [07:05:26] <aholler> maybe you have one of those xms with nand and you have saved stuff there and your changes (boot.scr) on the sd-card are ignored
  • [07:05:31] <linux_manju> aholler:My bug:- https://bugs.launchpad.net/ubuntu/maverick/+source/linux/+bug/663642
  • [07:06:33] <linux_manju> aholler: I dont think so.. with Maverick If I change default display to TV in boot.scr .. I used to get output from S-Video
  • [07:08:09] <linux_manju> aholler: that means.. its reading the boot.scr correctly.. And not ignoring / superseeding it
  • [07:08:34] <aholler> don't know anything about the ubuntu-kernel
  • [07:09:12] <linux_manju> aholler: What do you use?.. what BB revision, OS and Monitor
  • [07:09:29] <aholler> bb c4
  • [07:11:23] <linux_manju> aholler: which monitor/display ?
  • [07:11:55] <aholler> linux_manju: with cat /proc/cmdline you can verify you command line, check if it includes the changed resolution from boot.scr with an resolution your tv understands
  • [07:13:00] <aholler> e.g. try 640x480, almost every hdmi-capable tv should understand that
  • [07:13:19] <aholler> and try without MR
  • [07:15:08] <aholler> e.g. omapfb.mode=dvi:640x480-16@60

But under the same system environment, the Mplayer play the same 720p movie very smooth, nearly 24fps. and the CPU occupy is no more than 50%.

  • [10:28:09] <GGuyZ> I have configured the right parameters..

  • [13:16:29] <GGuyZ> As far as I've seen everyone mentioning they had used the evm are using TI's SDK and custom kernel. So I really think there's no way around it. They will know...

  • [13:30:01] <av500> this is a video encoder using CE XDM 1.0 api
  • [13:30:14] <av500> video decoder is even simpler
  • [13:30:33] <av500> and if you look into DMAI sources, you will find the code to drive a video decoder too
  • [13:31:14] <GGuyZ> Thanks, I'll dig into it :)
  • [13:31:56] <GGuyZ> This is probably a silly question, but how do XDM 1.0 and 1.2 differ? I.e: which one should I be using or it doesn't matter
  • [13:33:04] <av500> GGuyZ: it depends on which API to codec is

  • [19:45:30] <tasslehoff> I was just about to ask if it is recommended to work with a beagleboard-validation tree, the u-boot one. I consider making a new config for our custom board, and would like to work with "real code" instead of OE patches.
  • [19:45:36] <jkridner> nights and weekends. there must be some poor Linux expert around there not yet employed, no?
  • [19:46:11] <koen> tasslehoff: git am *.patch is not "real" enough for you?
  • [19:46:18] <jkridner> tasslehoff: you might run the risk of getting on koen's troll list. :)
  • [19:47:00] <tasslehoff> heh. I hit a sensitive/debaged topic?
  • [19:47:29] <jkridner> I will say that a rebase is easier with OE/patch and that git submodule feels pretty fragile.

  • [19:47:49] <koen> I don't get why people say "I don't want patches, I want a git tree"
  • [19:48:00] <koen> when they can do 'git am *.patch' themselves
  • [19:48:01] <jkridner> also, the patches in OE clearly spell out what is in mainline.
  • [19:48:12] <koen> just look at omapzoom or psp
  • [19:48:14] <tasslehoff> koen: maybe it is. I've just done small patches to the OE recipes until now, pretty much following http://bec-systems.com/site/456/capture-oe-source-changes
  • [19:48:17] <koen> gazillion git trees
  • [19:48:30] <koen> all cross merged
  • [19:48:35] <jkridner> koen: git remote add XYZ; git remote update; git cherry-pick is easy
  • [19:48:38] <aholler> jkridner: thats something different, talking about community means for me = unpaid, and everyone wants people who are doing stuff for nothing. And there isn't enough water to fill that bottle
  • [19:48:46] <jkridner> the cross merging is a mess.
  • [19:50:42] <aholler> just my ?? about community ;)
  • [19:51:32] <jkridner> koen: with OE, it is a multidimensional problem, because you also need to make sure the OE git tree is in the right place.
  • [19:51:45] <jkridner> koen: also, 'git rebase -i' is super nice.
  • [19:52:28] * jkridner copies new uImage to board.

  • [19:52:39] <koen> jkridner: I'm saying that people who want a git tree can git am stuff
  • [19:53:04] <jkridner> sure, but it does require some additional knowledge, where if you are already using git, git remote add is trivial.
  • [19:53:35] <jkridner> the fact that the patches aren't bundled in git is an issue...
  • [19:53:43] <jkridner> that is something I'd really like to see fixed in git.
  • [19:53:49] <av500> ?
  • [19:54:10] <tasslehoff> koen: don't understand the "git am *.patch", but is the workflow: compile OE, copy patched u-boot source somewhere, create local repo, hack - commit - create patches, put patches in OE recipe a sensible workflow?

  • [19:56:29] <tasslehoff> ah. of course. so just pull from the location in the recipe, create a branch from the version used, and apply the patches..
  • [19:56:52] <jkridner> koen: why aren't the recipes specified more by wildcards? wouldn't that make things easier than trying to manage the pointers within the recipes?

  • [22:03:25] <aholler> no
  • [22:03:53] <mru> if you can read and write the key you might as well use normal software crypto
  • [22:04:02] <AngryParsley> aholler: being able to get the key defeats the purpose. somebody would boot your computer off a usb key or cd and grab the key
  • [22:04:32] <mru> the entire point is tying a key securely to a device
  • [22:04:48] <thurbad> I got unknown package as well when I tried installing.. but http://www.angstrom-distribution.org/repo/?pkgname=man lists it
  • [22:04:58] <AngryParsley> weird
  • [22:05:08] <aholler> no, there just must a way to get and set the key through something which can't be done by everyone
  • [22:05:11] <mru> having it part of the cpu chip is a bit weird though
  • [22:05:41] <aholler> e.g. through some hw-dongle

  • [22:05:53] <AngryParsley> aholler: again, at that point you might as well get and set the key on a usb stick or something like that
  • [22:06:06] <aholler> no
  • [22:06:13] <thurbad> usb sticks fail too
  • [22:06:47] <AngryParsley> thurbad: they do, but at least you can keep it on you all the time instead of leaving it with your computer
  • [22:06:53] <AngryParsley> of course a TPM is even better
  • [22:06:54] <thurbad> but the pirates will always be able to circumvent it
  • [22:06:56] <aholler> i want the key in my computer do use it. But I want to be the one who defines the key
  • [22:07:02] <aholler> s/do/to/
  • [22:07:13] <mru> thurbad: I'm not talking about drm necessarily
  • [22:07:23] <mru> it applies to all kinds of encrypted communication
  • [22:07:40] <thurbad> true
  • [22:08:09] <John____> I tried to write a C++ program that utilizes OpenCV libraries, but it gave me an error: "error: cv.h: No such file or directory" "error: highgui.h: No such file or directory"
  • [22:08:10] <AngryParsley> aholler: maybe you want to use a yubikey then? they're pretty cool for multi-factor auth
  • [22:08:10] <mru> if the key is locked inside a hardware device you know there can only be one copy of it
  • [22:08:38] <AngryParsley> although yubikeys use a shared secret to generate the otp, so whatever you're validating against has to have that key too
  • [22:08:38] <mru> someone can steal the device containing the key, but then you know it
  • [22:08:46] <mru> and you can have it password protected
  • [22:08:52] <AngryParsley> we use them at work. they're a lot nicer than the RSA securids
  • [22:08:54] <John____> does anyone know where can I get the "highgui" and "cv" opencv libraries?
  • [22:09:18] <woglinde> opkg list | grep highgui
  • [22:09:24] <woglinde> opkg list | grep cv
  • [22:09:45] <mru> John____: did you install opencv-dev?
  • [22:10:30] <John____> no, do I need to install both "opkg install opencv" and "opkg install opencv-dev"?
  • [22:10:43] <aholler> I have an openkubus, but never used it. it's just to cumbersome to always have the token in reach. so I would prefer to use a tpm-chip in my computer to hold a key I defined.
  • [22:10:47] <thurbad> the dev package has the headers
  • [22:11:13] <thurbad> it will install the regular package along with it as a dependency most likely if you haven't already installed it
  • [22:11:26] <John____> ok

  • [22:50:21] <mr_mac3> Hello everyone! I have a quick question: How do you build your own kernel for the xM? More specifically, is the best way to use the codesourcery toolchain and the TI DVSDK kernel or build your own toolchain and use the OMAP Kernel git tree?
  • [22:50:42] <mru> are those the only two options?
  • [22:50:47] <mr_mac3> no

  • [22:51:15] <aholler> use whatever toolchain you wish
  • [22:51:31] <woglinde> mr_mac3 why not oe?
  • [22:51:59] <ds2> you build a kernel by running make
  • [22:52:04] <mr_mac3> ok so there is no reason to choose a specific verion of codesourcery or anything like that?
  • [22:52:22] <ds2> use any toolchain you feel like
  • [22:52:25] <woglinde> latest dvsdk says 2009q1
  • [22:52:27] <woglinde> orso
  • [22:52:48] <mru> I'd advise against any gcc 4.4 based compiler
  • [22:52:59] <mr_mac3> ok
  • [22:53:24] <mr_mac3> is there any difference betwen the kernel in the DVSDK and the OMAP tree?
  • [22:53:36] <woglinde> diff it
  • [22:54:03] <woglinde> you choosed the hard way anyway
  • [22:54:55] <mr_mac3> well it doesn't seem that hard
  • [22:55:03] <mru> building a kernel isn't hard
  • [22:55:22] <mru> at least not for those not asking those questions...
  • [22:55:23] <ds2> cross building a kernel is as about as simple as it gets
  • [22:55:42] <ds2> cross building perl on the other hand...
  • [22:55:46] <woglinde> he will fail at uImage
  • [22:57:10] <ds2> then use a bootloader that don't use uImages
  • [22:57:11] <ds2> :D
  • [22:58:09] <mr_mac3> Should I stick with a tarfile format filesystem?
  • [22:58:18] <woglinde> o.O
  • [22:58:36] <ds2> if you like userspace fs's
  • [22:59:13] <aholler> mr_mac3: the toolchain from linaro currently seems to heve the most usefull patches
