12:40.31 | VoodooZ | [g2]: somebody was having problems in #oe w/ threading. |
12:40.49 | [g2] | VoodooZ morning |
12:40.51 | VoodooZ | I know because I keep an eye on everything threading/glibc2.5 related. |
12:40.53 | VoodooZ | morning |
12:41.13 | VoodooZ | Just in case somebody figures out a way to get slugos to use glibc2.5 (NPTL). |
12:41.17 | VoodooZ | why? |
12:41.28 | [g2] | someone was asking about it |
12:41.37 | VoodooZ | oh |
12:41.42 | VoodooZ | remember his name? |
12:41.56 | [g2] | actually any version of glibc would probably be fine |
12:42.08 | [g2] | someone e-mail'ed me |
12:42.47 | [g2] | they were asking about threaded debugging and how well it worked |
12:42.53 | VoodooZ | I've used it a lot on my robot. (linuxthreads) |
12:43.22 | [g2] | so you done a lot of with glibc2.3 ? |
12:43.23 | VoodooZ | but never did debugging on it as it's apparently a pain without NPTL which is one more reason I want glibc2.5 |
12:43.39 | VoodooZ | well, I'm still stuck with slugos3.10 for that reason. |
12:44.02 | VoodooZ | but I didn't debug anything really. Just used threading. |
12:45.07 | [g2] | VoodooZ ok thx |
12:45.25 | VoodooZ | [g2]: what do you think of the new xscales (pxa3x0)? |
12:45.31 | VoodooZ | 1.2Ghz sure sounds nice. |
12:46.24 | [g2] | VoodooZ it's mildly interesting |
12:46.43 | [g2] | the 1.2G was the Intel version from what I read |
12:46.49 | [g2] | the Marvell is 800Mhz |
12:46.58 | VoodooZ | ah. |
12:47.00 | [g2] | that's not really far from the 533Mhz Lofts |
12:47.06 | VoodooZ | still, 800Mhz should be fast |
12:47.21 | [g2] | IMHO, the DDR memory controller makes a much bigger difference |
12:47.35 | VoodooZ | I'd like to see opencv compared on an ARM like the loft and a P3-900 for example. |
12:47.53 | VoodooZ | yeah, especially for vision stuff. lot of ram accesses. |
12:48.40 | VoodooZ | I was also reading about the Atmel AVR32 (as introduced in 2.6.19). |
12:49.05 | VoodooZ | has all the low-level hardware I need for robotics (PWM, I2C, SPI) and more. |
12:49.24 | VoodooZ | I especially like that pixel processor which basically does color space conversion for me. |
12:50.00 | VoodooZ | But at 133mhz it's not going to replace a real processor but could take care of low-level stuff nicely. |
12:58.49 | [g2] | VoodooZ did you see the 3DLabs announcement ? |
12:59.37 | [g2] | http://www.linuxdevices.com/news/NS6462226046.html |
13:00.01 | [g2] | that's the kinda think I imagine you'd really have a wet dream over |
13:00.28 | [g2] | couple of ARMs for housekeeping and a bad a** array processor |
13:00.52 | [g2] | and I/O BW thru the roof |
13:21.19 | *** join/#openslug CieD (n=CieD@81.168.95.39) |
13:39.35 | VoodooZ | [g2]: looks like a pretty fancy setup. |
13:40.37 | VoodooZ | [g2]: although It does sound like it would take ages to actually use that extra power. |

21:39.39 | NAiL | anyone know if the nslu2 kernel cmdline is stored in redboot config? |
21:54.59 | rwhitby | it's not |
22:05.31 | mwester | It's in the fixup code alongside nslu2-setup.c and friends... |

22:39.36 | NAiL | I don't mean the fixup code. I mean the original cmdline |
22:39.45 | NAiL | the one that the fixup code overrides |
22:40.28 | rwhitby | for slugos 3 it's compiled into the kernel CONFIG_CMDLINE |
22:40.39 | rwhitby | for slugos 4.1 now, it's passed to the kernel by apex |
22:41.03 | rwhitby | linksys redboot doesn't do cmdline (or any ATAGs for that matter) properly |
