  • [03:56:39] <emeb_mac> TangerineTriode: depends - not all DSPs are vector-based.
  • [03:57:43] <TangerineTriode> ok
  • [03:57:49] <emeb_mac> Some DSPs main distinguishing factor is that they have fast Multiply/Accumulate features
  • [03:58:25] <TangerineTriode> so, the c6000 is vector(ish)
  • [03:58:31] <emeb_mac> In the past the big deal was to be able to compute sum-of-products with minimal overhead
  • [03:58:38] <TangerineTriode> but other dsps are very different

  • [03:59:35] <TangerineTriode> i've just been trying to understan the c6000
  • [03:59:59] <emeb_mac> I haven't looked at that architecture too closely.
  • [04:00:16] <emeb_mac> More experience with older-style parts that were mainly used for audio
  • [04:00:21] <jkridner|work> C6000 is VLIW, not vector.
  • [04:00:38] <jkridner|work> 8 parallel execution units.
  • [04:00:49] <jkridner|work> they can do independent operations.
  • [04:00:52] <TangerineTriode> VLIW seems to be like vector with small vectors
  • [04:01:03] <emeb_mac> Yeah - a couple MACs, a couple ALUs and a couple Address generators.
  • [04:01:10] <jkridner|work> with vector, you must do the same operation on all the data.
  • [04:01:24] <emeb_mac> Yup - like x86 SIMD
  • [04:01:28] <jkridner|work> with VLIW, you can do different things with the various units.
  • [04:01:34] <TangerineTriode> and the cploop and cpkernel seem to turn arbitrary instructions into a large vector op
  • [04:01:35] <emeb_mac> just so
  • [04:01:53] <emeb_mac> vector yes, but not a single-cycle
  • [04:02:01] <emeb_mac> it iterates over the data
  • [04:02:15] <emeb_mac> with low overhead
  • [04:02:29] <TangerineTriode> i've done most of my work with RISC, so it's all new to me (sparc, arm)
  • [04:02:53] <emeb_mac> I've done some work with TMS320 and dsPIC
  • [04:02:57] <emeb_mac> more classical DSPs
  • [04:04:16] <jkridner|work> http://focus.ti.com/lit/ug/spru732g/spru732g.pdf is the C64x+ CPU overview and instruction set.
  • [04:05:53] <jkridner|work> if you look at figure 2-1, you can see it is like 8 RISC CPUs, each with different instruction sets, but with many instructions shared as well.
  • [04:06:15] <jkridner|work> each unit type has its own set of opcodes.
  • [04:06:23] <TangerineTriode> except that there are about 1000 instructions :)
  • [04:06:46] <emeb_mac> I'd imagine not a lot of folks try hand-coding assembly on that
  • [04:06:47] <jkridner|work> not on any given unit.
  • [04:07:08] <jkridner|work> unscheduled assembly is much easier than scheduled assembly.
  • [04:07:11] <emeb_mac> I used to work with ATT DSP3210.
  • [04:07:14] <emeb_mac> also VLIW
  • [04:07:20] <emeb_mac> Not a lot of fun to code for.
  • [04:07:25] <TangerineTriode> really?
  • [04:07:38] <TangerineTriode> i thought it looked interesting, if challenging
  • [04:07:48] <emeb_mac> big advantage was native floating point
  • [04:07:48] <jkridner|work> with unscheduled assembly, you can just write your assembly code, even without allocated the registers manually, and let the assembler parallelize and allocate registers.
  • [04:08:16] <jkridner|work> C67x/C674x has native floating point with similar architecture.
  • [04:08:20] <emeb_mac> Yeah - the DSP3210 assembler was almost a compiler too.
  • [04:08:41] <emeb_mac> did a lot of low-level gruntwork & scheduling for you.
  • [04:08:46] <jkridner|work> writing code in C with intrinsics gives pretty good results on the C64x.
  • [04:08:47] <emeb_mac> still kinda hairy though
  • [04:09:01] <emeb_mac> C + intrinsics sounds like the way to go.
  • [04:09:26] <jkridner|work> personally, I find the task of loop unrolling and scheduling kinda fun, in a bit of a sick way. No way I could justify the time to do it again though.
  • [04:09:44] <emeb_mac> You really have to _need_ it.
  • [04:10:07] <jkridner|work> yeah, it rarely makes sense.
  • [04:10:10] <TangerineTriode> so it's more of a code in C, do the important bits in assembly process?
  • [04:10:11] <emeb_mac> Most of the time, slap some mid-level C together & if it works move on.
  • [04:10:23] <emeb_mac> Yup
  • [04:10:25] <jkridner|work> absolutely.
  • [04:10:47] <emeb_mac> maybe break out the profiler to see if you need to tighten up
  • [04:10:55] <emeb_mac> most of the time not so much
  • [04:11:20] <TangerineTriode> it still looks kind of cool :)
  • [04:11:59] <emeb_mac> Sure - it's fun once in a while.
  • [04:12:15] <emeb_mac> get a sense of accomplishment for shaving off that last 1%

  • [04:15:25] <emeb_mac> In the short run it's probably easier & more interesting to optimize normal application code with NEON SIMD.
  • [04:16:20] <TangerineTriode> that sounds cool too
  • [04:16:38] <TangerineTriode> my main interest is in cryptography
  • [04:16:52] <emeb_mac> SIMD is probably ideal for crypto
  • [04:17:22] <emeb_mac> If you're trying to do brute force decrypt the DSP might be good though.
  • [04:17:43] <TangerineTriode> like bitslice des
  • [04:18:28] <TangerineTriode> but I know that aes has some relation to G(n) math, and I've been wondering if I could use the DSP to take some shortcuts
  • [04:19:00] <emeb_mac> Looks like some of the execution units on C6x have decent logical capabilities
  • [04:19:10] <emeb_mac> Those would be good for finite field arith
  • [04:20:19] <TangerineTriode> they have a few galois field operations
  • [04:20:56] <emeb_mac> There you go. Also good for FEC in wireless comms. GnuRadio guys would like that.
  • [04:21:12] <TangerineTriode> FEC?
  • [04:21:21] <emeb_mac> Forward Error Correction
  • [04:21:44] <emeb_mac> adding in parity check at TX to fix errors on RX end
  • [04:21:59] <emeb_mac> uses lots of finite field math
  • [04:22:33] <TangerineTriode> ok

  • [09:29:22] <sweetlilmre|work> koen: I am still having suid bit issues on the demo image (su). I extract the rootfs as 'tar xvf Angstron...bz2 -C /mnt' under the root user. but to no avail. owner and group are root, but suid bit is not set.
  • [09:31:12] <LoneMeow> and /mnt is not mounted with the nosuid option, I hope?
  • [09:32:00] <sweetlilmre|work> LoneMeow: okay, got me there... I mounted under root as 'mount /dev/sdc2 /mnt' how would I check the option?
  • [09:33:24] <LoneMeow> try just "mount" and it should show what's mounted and with what options
  • [09:35:38] <sweetlilmre|work> LoneMeow: '/dev/sdc2 on /mnt type ext3 (rw)'
  • [09:37:15] <LoneMeow> right, should be ok then
  • [09:37:29] <LoneMeow> can you manually set suid on some file there or does that fail too?
  • [09:37:48] <LoneMeow> "touch foo;chmod u+s foo;ls -lap foo" or something
  • [09:40:03] <sweetlilmre|work> that seems to work, su is linked to busybox, I can't specifically see the s flag tho: 'lrwxrwxrwx 1 root root ... su -> busybox'
  • [09:40:18] <LoneMeow> aaa symlink
  • [09:40:29] <LoneMeow> they're somewhat special
  • [09:40:33] <sweetlilmre|work> :)
  • [09:41:05] <sweetlilmre|work> so I assume 'chmod u+s su' is not going to cut the mustard?
  • [09:41:21] <sweetlilmre|work> let me try and see what happens
  • [09:41:43] <LoneMeow> as in, you can't set a symlink suid, you have to set the target suid (with all the implications that has)
  • [09:42:08] <sweetlilmre|work> so busybox would need suid... hmmm seems dangerous
  • [09:42:11] <LoneMeow> so in this case, you have to set the suid-bit for busybox, not the su-symlink
  • [09:42:24] <LoneMeow> and yes, that has some implications, though they're not that relevant on a singleuser embedded device usually ;)
  • [09:42:48] <LoneMeow> (busybox, when compiled properly, also knows to drop the EUID when the requested operation does not need that functionality)
  • [09:42:48] <sweetlilmre|work> but then everything (ls etc) gets suid...
  • [09:42:55] <sweetlilmre|work> ahh
  • [09:43:20] <sweetlilmre|work> interstingly enough chmod u+s on the link worked! I not have a root shell
  • [09:43:25] <sweetlilmre|work> ?!?
  • [09:43:37] <sweetlilmre|work> err 'now have a root shell'
  • [09:44:26] <LoneMeow> doing chmod u+s on a symlink follows the link and sets the bit on the target for me at least
  • [09:45:07] <sweetlilmre|work> LoneMeow: okay makes sense. Thanks a mil for the help. I am a windoze luser, but am slowing seeing the light :)
  • [09:45:15] <LoneMeow> no problem ;)
  • [09:45:21] <LoneMeow> now, for that lunch (this time for real) ->
  • [09:45:29] <sweetlilmre|work> LoneMeow: enjoy! :) me too!

  • [10:56:50] <kulve> Stskeeps: "that"? "any more"?
  • [10:57:06] <Stskeeps> kulve: if there was more work in acceleration
  • [10:57:17] <Stskeeps> (xf86-video-omap = that)
  • [10:58:25] <kulve> yeah, zuh is working on it.
  • [10:58:30] <Stskeeps> sounds good :)
  • [10:58:56] <Stskeeps> and my question was merely if there was a git to glance at to see the progress
  • [10:59:09] <LoneMeow> depends on what acceleration you're looking for, though...

  • [11:01:49] <khasim> has some one tried kiosk mode ?
  • [11:02:00] <khasim> in angstrom? does it support the same?
  • [11:04:54] <khasim> kulve: do you know if epiphany in angstrom support Kiosk mode? and how to enable it?
  • [11:05:18] <kulve> sorry, I don't know anything about epiphany..
  • [11:05:43] <koen> Stskeeps: xf86-video-omap is in the angstrom feeds, just 'opkg install xf86-video-omapfb' and edit xorg.conf
  • [11:05:49] <Stskeeps> *nod*
  • [11:06:06] <khasim> koen: ?
  • [11:07:40] * koen has no idea what kiosk mode is
  • [11:08:09] <khasim> Kiosk mode: disables most menus (including accelerators) so that only the edit, go, and tab menus remain. Bookmark editing is not allowed, settings cannot be changed, context menus have restricted navigation, image, email, properties, and link options. New windows cannot be opened, only new tabs (it is intended to run full screen).

  • [18:49:12] <dirk2> LWN about MontaVista's Vision 2008 conference http://lwn.net/Articles/301986/ : "According to William Mills, the Chief Technologist for Open Linux Solutions at Texas Instruments, ... TI now does its driver work in a public git tree, with a focus on merging the code upstream as a first priority". Anybody with an idea which git tree this might be?

  • [19:59:20] <denix> koen: there is no much performance difference for integer calculations, is it?
  • [19:59:43] <mru> optimal scheduling is different
  • [20:00:07] <koen> with the long cortex pipeline
  • [20:00:09] <denix> dirk2: not sure
  • [20:00:39] <koen> just look at how much faster things run on a pxa if you set the correct mtune
  • [20:00:45] <mru> most instructions have 2 cycles latency and need their input in the second cycle
  • [20:00:54] <mru> effectively 1-cycle latency
  • [20:01:32] <mru> one significant difference is the dual-issue capability of cortex-a8
  • [20:02:03] <ds2> koen: It is not slow.
  • [20:03:09] <mru> the instructions with multi-cycle latencies differ too
  • [20:03:12] <ds2> koen: if one were to ''hypothetically'' put Android on an OMAP3 platform...say Zoom... performance is pretty reasonable and for googlemaps, it is network choked
  • [20:04:00] <mru> think of the poor battery
  • [20:04:15] <mru> burning cycles while waiting for the network still drains the battery

  • [22:22:54] <vlad_> oh yeah; anyone have a native cs2007q3 handy?
  • [22:23:08] <vlad_> haha
  • [22:23:11] <vlad_> I didn't even see that
  • [22:23:31] <robclark> clamshell PDA.. xscale... I think their schedule did slip by a few years
  • [22:23:32] <geist> what, no mod?
  • [22:24:05] <florian> heh
  • [22:24:30] <mru> vlad_: do you mean the binary dist?
  • [22:24:31] <florian> koen: and a dillo release... incredible
  • [22:24:39] <vlad_> mru: yeah
  • [22:24:48] <mru> I deleted it
  • [22:25:02] <mru> after verifyin binutils was indeed broken

  • [22:25:44] * koen is thinking about building fennec for the iphone with OE
  • [22:25:55] <vlad_> for the iphone?!
  • [22:26:01] <vlad_> oh, with a different OS
  • [22:26:01] <florian> koen: dillo!!!
  • [22:26:01] <Pavlov> dooo ittttt
  • [22:26:02] <vlad_> wait
  • [22:26:13] <vlad_> OE runs on iphone?
  • [22:26:13] <koen> vlad_: no, for darwin
  • [22:26:19] <vlad_> oh
  • [22:26:24] <koen> vlad_: OE can build for darwin
  • [22:26:33] <vlad_> hrm
  • [22:26:37] <vlad_> using what widget/graphics layer?
  • [22:26:46] <koen> that's how the opened-hand^H^H^H^H intel people get clutter for iphone
  • [22:26:47] <Pavlov> i'd sure love the iphones touchscreen
  • [22:27:02] <vlad_> koen: well, clutter just ties in to opengl
  • [22:27:07] <koen> vlad_: probably gtk+ with quartz backend
  • [22:27:07] <vlad_> and a tiny bit to the widget system
  • [22:27:12] <vlad_> we tie in very heavily to the widget system
  • [22:27:32] <vlad_> gtk could maybe work, wouldn't be pretty
  • [22:27:43] <vlad_> it's not just a recompile at least, probably at least a month's worth of work :)
  • [22:28:25] <koen> vlad_: why does mozilla live in 1990?

  • [22:28:46] <vlad_> I don't understand the question
  • [22:28:55] <vlad_> really?
  • [22:29:02] <vlad_> how else do you get the last line in a file? :)
  • [22:29:12] <koen> especially since 'head' is saying that one should use 'head -n1' for some years now
  • [22:29:13] <vlad_> er, first

  • [22:51:34] <dcordes_> all s-video info I can find in the elinux wiki is a link to http://code.google.com/p/beagleboard/wiki/LinuxHints . /sys/class/display_control/omap_disp_control/graphics doesn't exist in my OE kernel build. does it only work with the reference kernel?
  • [22:52:06] <ds2> you need to apply a patch; the l-o framebuffer driver does not support s-video out
  • [22:53:22] <dcordes_> ds2, what is the best source for that patch?
  • [22:54:14] <ds2> look in the beagle mailling list archives; Nishemon (sorry, sp) has one that should apply to later kernels
  • [22:54:31] <ds2> the one I posted is for older 2.6.26/2.6.25 ish range
