| 15:00.18 | RobotGuy | harpal: It doesn't have to be S40. It could be S10, S20, or S83. The S script links run in order so you can control the order of when your processes are started. |

| 15:10.19 | GPSFan | I can find them in the /drivers/net/wireless/rt2x00 directory |
| 15:12.09 | GPSFan | ah, depends on MAC80211 and WLAN_80211 && EXPERIMENTAL |

| 15:14.50 | T0mW | I've got a new machine running with 7 SATA2 drives in a Raid0 configuration. I got a nice performance pop by using Raid0, but, can I eek out more performance by tuning the filesystem? Such as fstype and block / chunk sizes? |
| 15:15.34 | T0mW | I keep tuning in the chunk size on the raid, but no appreciable change occurs. |
| 15:16.18 | T0mW | anyone tune raid0 before? |
| 15:16.18 | GPSFan | RobotGuy: I can get it turn on in the config. no idea if it works. I don't have a raylink dongle. |
| 15:16.27 | chouimat|work | T0mW: sound like a nice machine |
| 15:16.44 | T0mW | chouimat|work: heh |
| 15:17.07 | RobotGuy | GPSFan: How did you get them in the config? |
| 15:17.45 | T0mW | chouimat|work: I was "only" going to upgrade the motherboard in the monster-box to one that could handle 8Gig of RAM. Well... |
| 15:18.36 | T0mW | chouimat|work: It started out as I realized that the new board only had one IDE interface on it and I needed two. Then it escalted from there into a new box. |
| 15:18.53 | T0mW | s/escalted/escalated |
| 15:18.54 | chouimat|work | T0mW: hehe ... I'm waiting a few months before doing this too ... I still have a 6 or 7 bays left in my main box |
| 15:19.54 | RobotGuy | I am getting a length error, but don't know why. I should have everything set correctly for my image sizes. |
| 15:20.21 | RobotGuy | I have a 1.7 MB compressed (6.9 MB uncompressed) initrd image. |
| 15:20.47 | T0mW | chouimat|work: If you want a really nice case, look at the Dynex DX-MTWER case that Best-Buy has. It is really better engineered than most Antec cases I have seen / bought! |
| 15:20.48 | RobotGuy | In Block Devices, I have 8192 currently set, but could go down to 7168. |
| 15:22.15 | T0mW | I'm been tuning using XFS for a while, now I'm trying ext3 with a 4K blocksize. |
| 15:22.20 | chouimat|work | T0mW: I have a huge tower(??), it has 10 5 1/4" bays and two others at the bottom of the case ... |
| 15:22.49 | chouimat|work | T0mW: I found that mfs.xfs -b size=512 -n size=4096 gave me good result |
| 15:23.00 | T0mW | chouimat|work: hmm, sounds like a 1000W supply and a bunch of 320G sata drives would do nicely |
| 15:23.27 | T0mW | chouimat|work: what chuck size on the raid? |
| 15:23.33 | T0mW | chouimat|work: what chunck size on the raid? |

| 15:23.48 | T0mW | ok |
| 15:24.06 | chouimat|work | T0mW: this case is about 33" high ... and it's on wheel |
| 15:24.17 | T0mW | chouimat|work: before I wrap this testing up an go into production with it, I'll try your xfs parms |

| 16:22.02 | RobotGuy | Whoopsy. I think I found the problem. |
| 16:23.41 | RobotGuy | prpplague: So, I put the same value as in .size into the compressed ramdisk size of Platform setup? |
| 16:23.55 | prpplague | RobotGuy: no |
| 16:24.35 | prpplague | RobotGuy: if your compressed initrd is less than 2mb, set the size to 2mb |
| 16:24.59 | RobotGuy | prpplague: That's what .size should be also. |
| 16:25.08 | prpplague | no |
| 16:25.33 | prpplague | the .size represents the kernel+ramdisk+bootloader |
| 16:26.06 | RobotGuy | prpplague: .size = 0x340000, |
| 16:26.39 | prpplague | RobotGuy: i don't what items your are setting or their size so i can't say if that is correct |
| 16:26.40 | RobotGuy | prpplague: It should probably be 4 MB then. |
| 16:27.58 | RobotGuy | That's in the arch/arm/mach-s3c2410/mach-tct_hammer.c file |
| 16:28.22 | prpplague | yea |
| 16:29.26 | RobotGuy | I was having a boundary problem and you gave me that value, which fixed that problem. Maybe it is too small now. 2 MB for initrd and 1 MB for kernel are the limits I am trying to stick to. |
| 16:30.57 | prpplague | RobotGuy: here is how to calculate your size 256k(bootloader)+1024k(kernel)+size_of_compressed_ramdisk |
| 16:31.20 | RobotGuy | prpplague: A little over 3 MB |
| 16:32.12 | RobotGuy | So I should set that to 4 MB to have a little room to grow if needed. I don't know what hex value that would be though to stay on a boundary. |

| 16:44.57 | agaffney | nano is a great little editor |
| 16:45.16 | adyer | the original idea of /bin was for stuff that would always be available on the system, whereas /usr/bin could be unmounted for maintenance, etc, so vi or some other small editor is often in /bin |
| 16:45.25 | RobotGuy | I 'spose that means I have to learn about diff and how to create a diff. |
| 16:45.49 | RobotGuy | adyer: That idea does not necessarily work for embedded systems. |
| 16:48.14 | adyer | I think of knowing a little vi as a survival skill, kind of like EDLIN in the dos days |
| 16:48.18 | RobotGuy | I would have to build both nano and libintl into my initrd at present to use nano. I'm not going to do that. |

| 19:17.51 | prpplague | RobotGuy: we already use it in a linux device, the 8385 is in the main tree |
| 19:18.37 | RobotGuy | prpplague: Very cool. OK, so all you have to do now is put it in a module anyone can use on a robot. :D:D |
| 19:18.51 | prpplague | its already in module format |
| 19:19.08 | RobotGuy | prpplague: I wonder if you could interface to it in ways other than SDIO. |
| 19:19.21 | prpplague | RobotGuy: 8385 supports cf and spi |
| 19:19.59 | RobotGuy | prpplague: Hmmmmm, interesting. The MMC/SD slot on the Hammer Carrier is just SPI, right? |
| 19:21.08 | prpplague | correct |

| 19:21.43 | prpplague | RobotGuy: no |
| 19:21.52 | RobotGuy | Really? |
| 19:22.06 | prpplague | it's an spi interface |

| 19:22.17 | prpplague | anything that can do sdi and be used on that port |
| 19:23.05 | RobotGuy | Right, but the SPI used with the SD/MMC slot on the carrier is just for mass storage. |
| 19:23.28 | RobotGuy | I am going to have to learn SPI at some point. |

| 20:12.31 | LyosNorezel | that's the firmware to an adtran NetVanta 1224R... the funny thing is... that file is just a gzipped file with a small header... |
| 20:12.50 | LyosNorezel | and some of what gzip calls "trailing garbage" |
| 20:13.05 | LyosNorezel | probably an md5 hash or similar |
| 20:13.34 | LyosNorezel | the gzipped file decompresses out to a 18MB file |
| 20:14.05 | LyosNorezel | that's just named "image" |
| 20:15.51 | prpplague | interesting |
| 20:16.55 | LyosNorezel | prpplague: what I'd really love to try an extract from that... is Adtran's "driver" for the Broadcom StrataSwitch II chip that's the heart and soul of this router |
| 20:17.16 | LyosNorezel | and which linux does not have a driver for |
| 20:17.54 | LyosNorezel | any thoughts on the "format" of the image? |
| 20:29.46 | adyer | LyosNorezel: looking at the upgrade docs it looks like there is some boot firmware in the system that then loads this image file, so it could be a lot of things. |
| 20:30.29 | LyosNorezel | interesting |
| 20:31.18 | adyer | maybe try running 'strings' on the expanded binary blob |
| 20:34.36 | LyosNorezel | holly holy |

| 20:46.06 | LyosNorezel | I find it unusually interesting that there's so much readable text... |

| 22:06.56 | LyosNorezel | interesting... it looks like it may indeed be an SOC of a fashion |
| 22:07.28 | LyosNorezel | wonder why they are running it through Broadcom's StrataSwitch II chip |
| 22:07.29 | LyosNorezel | ? |
| 22:07.59 | ds2 | probally cuz it can't handle the datarate |
| 22:08.07 | ds2 | LyosNorezel: what interfaces is on there? |
| 22:08.23 | LyosNorezel | PCMCIA, PCI, Serial |
| 22:08.29 | ds2 | I mean router interface |
| 22:08.38 | ds2 | what does it route amoung |
| 22:08.41 | ds2 | or between |
| 22:08.57 | LyosNorezel | all 10/100 ethernet... to a DBU/T1 card |
| 22:09.26 | ds2 | wild guess - the 10/100 routing is done by the broadcom chip |
| 22:09.32 | LyosNorezel | yep |
| 22:09.47 | ds2 | and interfaces with the MPC via the MPC's ethernet; the MPC is setup to talk to the TI/E1 interface |
| 22:10.02 | ds2 | most likely the DBU/T1 card is just the magnetics and isolation for it |
| 22:10.04 | LyosNorezel | could be |
| 22:10.36 | LyosNorezel | though the DBU/T1 card runs through, what looks like, a PCMCIA port |
| 22:10.39 | ds2 | cuz the MPC8[56]x are pretty much everything you need to go from ethernet to almost any Telcom standard be it T1 or ATM or xDSL |
| 22:10.57 | LyosNorezel | interesting |

| 22:11.11 | ds2 | Lyosnorezel: I doubt it is a PCMCIA port; I suspect it is like a Cisco WIC |
| 22:11.22 | LyosNorezel | WIC? |
| 22:11.59 | ds2 | WAN Interface Card; it is the thing Cisco uses on their lower end "modular" routers like the 16xx's, 17xx's and some 36xx/26xx (via a carrier NM module) |
| 22:12.14 | LyosNorezel | interesting |
| 22:12.40 | ds2 | FWIW, the Cisco 8xx's are basically the MPC8[56]x with a bunch of PHYs and memory on a board |
| 22:13.21 | LyosNorezel | ds2: know anything about firmware cracking? |
| 22:13.34 | ds2 | LyosNorezel: unfortunately, no |
| 22:13.39 | LyosNorezel | damn |
| 22:13.54 | ds2 | the MPC's are a relatively "friendly" chip |
| 22:13.59 | ds2 | messed with it before |
| 22:14.20 | LyosNorezel | I'd be happy to blast away their crappy AdtranOS... but I need it to get the driver for the Broadcom chip |
| 22:22.13 | adyer | LyosNorezel: do you know if the MPC chip hooks to the switch chip via ethernet or PCI? |
| 22:22.53 | LyosNorezel | adyer: no... I can't... but the switch chip is a PCI chip |
| 22:23.53 | adyer | doesn;t mean they use the feature :-) |
| 22:24.00 | LyosNorezel | lol |
| 22:26.00 | LyosNorezel | adyer: just judging from the rated speeds alone... I'd have to say PCI |
| 22:28.28 | LyosNorezel | adyer: "1224R:4.8Gbps" <<-- that the "Maximum Forward Bandwidth" |
| 22:29.27 | LyosNorezel | "Routing Performance" gives this rating: "30,000PPS" |

| 22:43.56 | Madsy | When using the ELF format, does the actual adressing of variables in the .text section depend on the .data section? Or are they completely independent? |
| 22:45.13 | Madsy | What I really want to do, is to modify or add an array in the .data section, and reflect the changes done so the ELF will run. |
| 22:45.58 | *** part/#edev LyosNorezel (n=LyosNore@unaffiliated/lyosnorezel) |
| 22:46.21 | Madsy | Where "ELF" in this case will always be a standalone executable. Not a library of any sort. |
| 22:48.43 | adyer | Madsy: I think it depends on whether the ELF has relocations in it. |
| 22:50.20 | Madsy | What does reallocations mean in this context? Whether the adressing is done absolute, or relative? |
| 22:50.24 | adyer | Madsy: if it's prelinked to an address the loader doesn't have to process the relocations and won't mess with stuff you're patching |
| 22:50.52 | Madsy | As I said, this will never be used for anything else than vanilla applications, so assume that -fPIC will never be used. |
| 22:51.08 | Madsy | aha |
| 22:53.14 | Madsy | I better read some more on the ARM ELF specs to understand this :-\ |
| 22:54.00 | Madsy | For some time, I thought that ELF images were dumped straight to memory as-is. |
