  • [01:36:29] <djlewis> you curious on results?
  • [01:36:43] <djlewis> only take a few minutes

  • [07:11:29] <vhallac> hi
  • [07:19:02] <kirma> can someone point me towards resource that would explain Cortex-A8 cache prefetch prediction? like sequential access, strides, whatever... and what's implemented and what not.
  • [07:25:38] <ds2> tried ARM ARM?
  • [07:25:50] <koen> good morning all
  • [07:25:59] <ds2> morning koen
  • [07:28:37] <ldesnogu> kirma: I don't think this is documented; the only place where it could is the Cortex-A8 TRM on ARM site
  • [07:28:58] <kirma> maybe it's *somewhere* in TRM
  • [07:29:14] <ldesnogu> use your pdf search function :-)
  • [07:29:35] <kirma> complete lack of automatic prefetching would be odd, but lots of intelligence would be too...
  • [07:29:54] <ldesnogu> are you talking of data or instruction prefetch?
  • [07:30:54] <kirma> data mainly
  • [07:31:02] <ldesnogu> I don't think A8 has that
  • [07:31:15] <ldesnogu> but don't take my word on it, I don't know A8 very well
  • [07:31:59] <kirma> that would be quite an incentive to sprinkle lots of explicit preload hints on the code :o
  • [07:32:09] <ldesnogu> and that's how it's done
  • [07:32:20] <ldesnogu> pld all around the place :)
  • [07:32:45] <ldesnogu> even x86 code uses explicit preload instructions
  • [07:33:01] <ldesnogu> the rationale is that the programmer always knows better than the hardware
  • [07:35:08] <kirma> ldesnogu: well, "use" ... there's usually logic predicting sequential access at least
  • [07:35:41] <kirma> surprisingly, L1-L2 access doesn't do stride prediction on x86s
  • [07:35:46] <ldesnogu> define "usually"
  • [07:35:54] <ldesnogu> and exceptions when there's page crossing
  • [07:36:08] <ldesnogu> and other details that make your prefetcher useless ;)
  • [07:36:20] <kirma> I think I've seen it on intel and amd docs
  • [07:36:39] <ldesnogu> IIRC Intel Optim manual describes some of the data prefetcher limitations
  • [07:36:54] <kirma> of course page crossings and such stuff is something that's beyond what automatic prefetcher could handle
  • [07:36:55] <ldesnogu> which are different depending on the core
  • [07:37:03] <kirma> true, they vary
  • [07:37:16] <ldesnogu> not necessarily: your prefetcher could use the MMU
  • [07:37:27] <ldesnogu> but I don't know if Intel does that
  • [07:37:47] <kirma> x86 cores are quite black boxes anyway in their function, of course they try to maintain semantics of the external view though...
  • [07:38:21] <ldesnogu> yes they are funny beasts
  • [07:38:26] <ldesnogu> and I hate them :-)
  • [07:38:33] <kirma> I suspect no implementation really does the prefetch if it generates a TLB miss
  • [07:38:37] <kirma> too complicated on silicon
  • [07:38:38] * jserv-- (n=jserv@61-30-10-70.static.tfn.net.tw) Quit (Read error: 145 (Connection timed out))
  • [07:38:45] <ldesnogu> probably
  • [07:39:04] <ldesnogu> but it could still do lookups and so allow cross-page prefetch
  • [07:39:38] <kirma> anyway, Cortex-A8 TRM indeed speaks of instruction cache speculation, but not a word on data cache speculation
  • [07:40:47] <ldesnogu> A9 has that
  • [07:41:08] <kirma> hmm

  • [07:43:23] * kirma is looking at A8 because: he has preordered Nokia N900 with it, and he would be interested to have native JIT for PyPy on it.
  • [07:43:53] <kirma> and that JIT would, of course, generate direct machine code stating everything explicitly.
  • [07:44:05] <ldesnogu> do you really need prefetching for that?
  • [07:44:12] * booxter (n=booxter@cpmsq.epam.com) has joined #beagle
  • [07:44:38] <kirma> of course it's not absolutely necessary, but I'm trying to get the whole picture of the scheduling...
  • [07:44:45] <ldesnogu> well I guess my question doesn't make sense; prefetching is always a plus :0
  • [07:45:03] <ldesnogu> you intend on scheduling code?
  • [07:45:06] <kirma> well, over-eager sprinkling of prefetch instructions isn't necessarily
  • [07:45:59] <ldesnogu> I don't know of any JIT that does instruction scheduling (unless some very primitive form)
  • [07:46:22] <kirma> yeah, it's probably a bit over-eager way of thinking it
  • [07:46:43] <kirma> but understanding what's possible is useful still :)
  • [07:46:58] <kirma> I haven't looked at ARM implementation details for years...
  • [07:47:19] <ldesnogu> things changed a lot :)

  • [09:07:57] <vhallac> Hi, a quick question about the GPIO_29. In the versions of the kernel I looked at, mmc1 WP bit is connected to GPIO29, and pad is configured as GPIO
  • [09:08:06] <vhallac> But from beagle schematics it is used for USB2
  • [09:08:32] <vhallac> And GPIO 23 is the MMC WP
  • [09:09:41] <niral> hi keon
  • [09:09:45] <vhallac> Which one is correct? The kernel, or the schematics?
  • [09:12:44] <niral> dash this is my code http://pastebin.com/d591e9fc9

  • [09:45:20] <vhallac> Got my answer. GPIO 29 is the MMC1 WP on rev B boards. It moved to 23 on Rev C.
  • [09:45:49] <vhallac> I wonder if this could be related to USB host port issues in rev C boards.

  • [10:51:40] <adj> kirma: use fi.digikey.com (or digikey.fi) when making the order. You'll get free shipping.
  • [10:52:23] <kirma> adj: does that work for individuals too?
  • [10:53:04] <dirk2> kirma: digikey shipping is free, but be aware of customs/tax if you order from digikey
  • [10:53:57] <dirk2> kirma: EBV Beagle is more expensive (EUR 179,-), but you will get some additional peripherals
  • [10:54:14] <dirk2> kirma: Check http://elinux.org/BeagleBoard#Availability
  • [10:55:58] <kirma> do these boards work well in headless configurations? ... if my primary interest is benchmarking CPU performance of applications running on Maemo/Linux...
  • [10:57:00] <adj> yeah, when importing you'll have to pay at least 22% finnish tax but the total price will still be ~130 eur
  • [10:58:14] <kirma> I'm thinking about serial boot console and rest over ethernet, no display or such connected... feasible?

  • [11:02:18] <likewise> How long did it take for getting a response on the SGX SDK for you guys?
  • [11:07:21] <kirma> all this seems a bit too much hassle eventually :o ... with need for separate case, especially, and ordering all that all around. gets more expensive than one might optimistically think.

  • [12:44:33] <_dash_> hey adj finaaly that problem with OTG solver
  • [12:44:38] <_dash_> solved
  • [12:44:56] <_dash_> with minimal config change in kernel
  • [12:45:19] <_dash_> but I want to report this thing to man who manages this OTG driver
  • [12:45:34] <kblin> _dash_: what kind of problem?
  • [12:45:49] <_dash_> hello kblin
  • [12:46:21] <_dash_> I was trying to connect HUB to OTG _before_ kernel boot ing
  • [12:46:53] <_dash_> but kernel was unable to enumerate the same if hub is powered on
  • [12:47:04] <kblin> ah, right
  • [12:47:14] <kblin> now I remember seeing you talk about that
  • [12:47:41] <_dash_> kblin: in kernel config there are 2 options for OTG
  • [12:47:45] <adj> _dash_: what was the solution?
  • [12:48:17] <adj> i think people on bb mailing list might also be interested in that
  • [12:48:39] <_dash_> yeh
  • [12:48:47] <_dash_> I will update that also
  • [12:49:11] <_dash_> I changed kernel config as follows

  • [12:53:14] <_dash_> If u use mini A cable still it fails
  • [12:54:08] <_dash_> but if u select option 1 and plug in hub _before_ kernel booting it works and enumerates all devices
  • [12:54:27] <_dash_> in case 3 same thing does not work
  • [12:54:47] <_dash_> u require to plug in Hub _after_ booting
  • [12:55:17] <_dash_> as my purpose was to use it only as host I changed to that setting which may not be feasible in other cases
  • [12:56:00] <_dash_> adj: kblin: any comment ojn this ??

  • [14:31:44] <sakoman> that price isn't too bad
  • [14:31:44] <prpplague> sakoman: hey, while i have you here, i've got a prototype version of another expansion board that i wanted to get your opinion on
  • [14:31:44] <sakoman> prpplague: ok
  • [14:31:44] <_av500_> what doz it do?
  • [14:31:44] <prpplague> sakoman: basically it is a break out board, i2c, spi, atmega320(connected via uart), with each section selectable with either +3.3v levels or +5v levels , along with some proto area
  • [14:31:44] <koen> hrw: note that I haven't runtime tested .31rc yet, just trying to make it more complete :)

  • [14:31:44] <_av500_> sakoman: i recommend i7
  • [14:31:44] <prpplague> likewise: yea actually it's probably the most silent machine i've ever owned
  • [14:31:44] <sakoman> prpplague: that's why I've never done it, I worry the support cost for something like that would destroy any profit margin, (or make it too expensive)
  • [14:31:44] <prpplague> likewise: the fans only really kick in when i get about 6 tasks running with OE heavily
  • [14:31:44] <prpplague> sakoman: support costs?

  • [14:31:44] <sakoman> prpplague: the time you will spend expalining to newbie experimenters how to make the thing work
  • [14:31:44] <koen> sakoman: .31rc needs the arch-has-holes patch applied otherwise all the dsp stuff won't work
  • [14:31:44] <bobkatzz> sakoman: so even if the processor is really really fast you're bottleneck is still the drive speed?
  • [14:31:44] <likewise> sakoman: 2.6.31-rc upstream or with additional omap patches?
  • [14:31:44] <sakoman> koen: I haven't been doing any dsp stuff :-)

  • [18:45:00] <surikatga> maybe, anyone have some experience with using openembedded+angstrom+OMAP35x_Graphics_SDK_3_00_00_06 and compiling own apps?
  • [18:45:53] <koen> sakoman_: I dislike the machine mandating all modules, images are better suited for that
  • [18:47:05] <prpplague> koen: hey, i was going to ask, is there a reason that the base angstrom build doesn't generate a x-load.bin.ift file? or am i just missing where it is stored?
  • [18:47:49] <koen> I suspect xload isn't in EXTRA_IMAGE_DEPENDS
  • [18:49:11] <koen> sakoman_: and I'm also curious why you choose micro, there's no reason angstrom can't generate the same size images as micro
  • [18:49:38] <koen> (especially since micro is 90% based on OE features I added for angstrom)
  • [18:49:40] <bobbarker> has anyone here manufactured a board with an OAMP3? how much $$$ do you think im looking at for 1-3 boards + population of the BGA parts
  • [18:49:42] <prpplague> koen: it builds the x-load.bin and the signGP, but doesn't appear to actually generate the ift
  • [18:49:57] <prpplague> bobbarker: a bunch
  • [18:50:17] <koen> prpplague: ah, the .ift is a red herring
  • [18:50:26] <bobbarker> is it possible to get under $300 / board?
  • [18:50:28] <koen> prpplague: xload.bin works just as well
  • [18:50:43] <prpplague> bobbarker: uh no , not for 1-3 boards
  • [18:50:57] <prpplague> koen: ahh so the signing isn't that important?
  • [18:51:01] <koen> prpplague: only the old, old TI 1.41 version needed seperate versions for nand and sd, 1.4.2 can do both
  • [18:51:09] <bobbarker> prpplague, dang... damn my uni for not having BGA capable facilities! :(
  • [18:51:14] <koen> xload.bin should already be signed
  • [18:51:18] <prpplague> koen: ahh
  • [18:51:23] <prpplague> koen: dandy
  • [18:51:43] <prpplague> bobbarker: why do you need to do your own design for 1-3 boards?
  • [18:51:54] <prpplague> bobbarker: why not get one of the off-the-shelf designs?
  • [18:52:31] <prpplague> bobbarker: http://www.kwikbyte.com/KBOC.html
  • [18:52:36] <prpplague> bobbarker: or gumstix
  • [18:52:50] <bobbarker> prpplague, senior design. a premade board is considered too "easy" for the project
  • [18:53:16] <prpplague> bobbarker: what is the project?
  • [18:53:21] <bobbarker> prpplague, even with a support board of our own design
  • [18:53:43] <bobbarker> prpplague, at this point some sort of information kiosk, jazzed up and flashy, of course :)
  • [18:54:27] <prpplague> thats a pretty tall order for $300 per unit
  • [18:54:45] <bobbarker> on a similar note, does anybody know of a source of large (12"+) LCD panels that don't cost an arm and a leg?
  • [18:55:07] <bobbarker> prpplague, the $300 figure would be just for board manufacture and population, not the rest of the kiosk
  • [18:55:27] <cbrake> sakoman: updated to your actual rc8 patch set (from yesterday) http://cgit.bec-systems.com/cgit.cgi/linux-2.6/log/?h=linux-omap-beagle-overo-2.6.31-rc8-bec2
  • [18:55:29] <prpplague> bobbarker: earthlcd.com has a number of good lcd's, not all are RoHS, but that shouldn't matter for you
  • [18:55:59] <bobbarker> ive seen some panels but they sell for $250+ for 12", a far cry from say $150 for a 22" monitor... of course the quantities for monitors are staggering
  • [18:56:06] <bobbarker> prpplague, thanks, i'll check it out
  • [18:56:30] <prpplague> bobbarker: even of just the main board, that is going to be pretty hard to match for BGA multilayer boards
  • [18:56:36] <prpplague> bobbarker: for that small of a run
  • [18:56:46] <bobbarker> im not averse to tearing the panel out of a monitor but the almost certain lack of datasheet would be a major roadblock
  • [18:56:58] <prpplague> bobbarker: you have to do the whole cpu design?
  • [18:57:24] <bobbarker> prpplague, i was thinking the same... i was hoping that student begging might lead a manufacturer to subsidize the cost
  • [18:57:29] <prpplague> bobbarker: the break point on cost is right at the 10" mark
  • [18:57:51] <bobbarker> prpplague, do you mean the whole single board computer design?

  • [18:58:03] <prpplague> bobbarker: correct
  • [18:58:39] <bobbarker> prpplague, designing the entire board would be much more impressive from the instructors perspective
  • [18:58:55] <cbrake> koen: thanks for the git am suggestion. I actually ended up just sucking the patch files out of the patches directory in the work dir. I still had to add missing email addresses to some of the patch files.
  • [18:59:22] <bobbarker> prpplague, and while im guessing the layout for such beastly parts would be hard, the nice thing is that the parts are so featureful that only a few ICs would be needed
  • [18:59:38] <prpplague> bobbarker: might i suggest then you scale back and look at using an arm9 or even an arm7 that is in a qfp package and running at less than 100mhz
  • [19:00:00] <_av500_> bobbarker: doing a student omap3 design is tough

  • [19:00:14] <bobbarker> prpplague, i looked into those at first but they all seemed to lack the ability to drive a large, higher-res panel to make pretty GUIs :)
  • [19:00:48] <_av500_> then use bb+lcd
  • [19:00:49] <prpplague> bobbarker: they'll do it, just gotta be careful with the GUI
  • [19:01:39] <sakoman_> cbrake: nice! now we can point people there who want a kernel git repo that requires no patches
  • [19:01:41] <bobbarker> _av500_, i think this is what we will be forced to do, and satisfying the "make a pcb" requirement with a support board (say touch screen interface and LCD signal translation)
  • [19:02:12] <sakoman_> cbrake, koen: do you know which kernel rev ubifs first became usable?
  • [19:02:46] <_av500_> bobbarker: yep
  • [19:02:53] <_av500_> sounds good to me
  • [19:03:37] <bobbarker> prpplague, i looked at some atmel ARMs with a built in LCD driver and the internal buses looked like they were going to struggle to have the bandwidth for 800x600+ at 30hz
  • [19:03:51] <_av500_> if you want your pcb fancy add a cpld or so to do something
  • [19:04:14] <bobbarker> _av500_, or a quantum processor :-P
  • [19:04:27] <_av500_> extra creds for that

  • [19:16:52] <cbrake> sakoman: http://pastebin.ca/1554147
  • [19:18:58] <prpplague> bobbarker: i've done three kiosk designs, and i suspect you are going to have a rough go of it if you set your goals too high for both hardware, production, and software, gotta have some trade offs
  • [19:21:34] <bobbarker> prpplague, got it. i think we will definitely simplify the hardware (use a BB or even an intel donated atom board) and focus on the software

  • [19:23:35] <prpplague> bobbarker: i'd recommend using a gumstix or kwikbits boards
  • [19:26:46] <sakoman_> cbrake: I eventually want it to be handled via the config eeprom
  • [19:27:24] <bobbarker> prpplague, do they have boards with much gfx power now? when i looked at them a few years ago gfx support was either absent or whimpy

  • [19:31:25] <bobbarker> prpplague, thanks
  • [19:31:39] <sakoman_> it's a 128 byte eeprom, very common and low cost
  • [19:31:48] <bobbarker> well im off to catch a flight... i hope the TSA doesnt think im of any interest
  • [19:31:50] <cbrake> sakoman_: is the eeprom programmed in production or blank?
