(10:59:16) andguent: puddingpimp: no the opengl stuff is just big blob from powervr
(10:59:56) mjl-: morning
(11:00:07) andguent: morning
(11:00:15) mjl-: the beagle board is a bit troublesome indeed
(11:00:20) mjl-: it also doesn't seem to have serial
(11:00:26) mjl-: so hard to get started with
(11:00:26) mjl-: iirc
(11:03:24) andguent: it has a rs232
(11:03:27) andguent: also jtag
(11:05:04) mjl-: hmm, ok, then my info was wrong
(11:10:42) mjl-: andguent: that rs232 is not something over usb, right?
(11:13:06) andguent: afaik it;s physical rs232 wires coming out of the board
(11:14:40) andguent: p9/inferno on the beagleboard would be indeed very interesting
(11:14:54) andguent: it would make a nice low cost server
(11:15:04) andguent: also i am kind of looking what happens with the touch book
(11:15:11) uriel: well, the only advantage of the beagle over the sheeva is that it has videou output
(11:15:15) andguent: which is basically a beagleboard in a laptop case
(11:15:38) uriel: the sheeva has even more cpu power AFAIK, and a few other advantages
(11:15:43) mjl-: yes
(11:15:51) mjl-: the beagle board has a mobile phone chip
(11:15:54) mjl-: that says a lot
(11:15:54) uriel: (plus is like one third of the cost)
(11:16:02) uriel: mjl-: ah, didn't notice that
(11:16:29) uriel: mjl-: hmmm... can it take a sim card?
(11:16:30) mjl-: yeah, it's an omap3 chip
(11:16:35) mjl-: i bet it cannot :)
(11:16:38) mjl-: i bet there i no gsm chip
(11:16:42) mjl-: those are separate
(11:16:52) npe [n=npe@195.207.5.2] entered the room.
(11:17:01) andguent: mjl-: i can't help it. but apart from the powervr desaster i can only love the omap chip
(11:17:08) mjl-: actually a gsm chip would be connected over a serial line for control, and then some wires for audio.  pretty much not integrated at all
(11:17:24) mjl-: andguent: i agree, the omap chip looks quite impressive
(11:17:44) mjl-: i bet a beagle board uses less power than a sheevaplug
(11:17:45) andguent: i'd also love to play around with the TI dsp chip
(11:17:58) mjl-: are docs for that online?
(11:18:02) andguent: yeah
(11:18:03) mjl-: /available
(11:18:06) andguent: completely documented
(11:18:06) mjl-: ah good
(11:18:27) mjl-: that's sucky about the arm core in it, the cortax a8 (i think):  you cannot get docs from arm on them
(11:18:35) mjl-: i.e. the newer stuff is not documented
(11:18:40) andguent: meaning?
(11:18:44) mjl-: well, you can get docs if you request them with a good reason
(11:18:59) mjl-: the new instructions, and how some of the internals work
(11:19:25) mjl-: i don't think it's multicore (the thing in the omap), but the newer cortex'es are multicore
(11:19:30) andguent: hmkay. but i think there are ways to get that information nevertheless
(11:22:00) andguent: well at one point i'd like to do some kernel hacking
(11:22:13) andguent: but for now i better read nemos 3rd kernel doc

(14:54:59) h2ro [n=j@cable-87-78-195-56.netcologne.de] entered the room.
(14:55:09) h2ro: hey guys, is there something like vt for inferno?
(15:26:23) soul9: can anyone point me to a mips/arm design that has performance comparable to todays pc's?
(15:31:55) anothy_x: if by "todays pc" you mean the 8-core atom whatever, then no, i don't believe anyone can, because i don't believe it exists.
(15:32:33) soul9: well, yeah, something like a single core 2Ghz core2 or something
(15:32:39) soul9: anothy_x↑
(15:34:22) soul9: s/something$// ☻
(15:34:54) anothy_x: i think the top end still lags that. i've seen talk of arm cortex devices up to about 1ghz, but i can't do an exact flop comparison.
(15:35:25) soul9: yeah, it is difficult to compare the two
(15:35:27) soul9: thanks
(15:35:57) anothy_x: but if you're looking to actually buy something (or considering it), look for that 1ghz arm cortex.
(15:36:10) anothy_x: and then let us know what you come up with! i'd love an arm terminal for a decent price.
(15:36:25) soul9: yeah, i'd love to ditch x86 :-)
(15:36:25) anothy_x: off to check out and the last day of IWP9.
(15:36:35) soul9: cheers!
(15:36:37) anothy_x: wish y'all were here! remember the streaming video!
(15:36:57) soul9: yeah, wish i could come, must be fun :-)
