| 01:43.42 | solar | rewrite the kernel? |
| 01:43.48 | solar | you mean uploading it? |
| 01:46.49 | Mirell | solar: Nah man, rewriting it entirely. |
| 01:51.10 | SpeedEvil | That would be cool - http://www.mentby.com/rob-landley/what-happened-to-linux-tiny.html |
| 01:52.08 | Mirell | Heh |
| 01:53.34 | SpeedEvil | 'I'm sorry, I'm confused by the CONCEPT of having a shortage of TODO items.  |
| 01:53.34 | SpeedEvil | This is just the top of my head _Linux_ stuff, and doesn't include purely-me |
| 01:53.34 | SpeedEvil | items like learning LUA.  I want to get a mac and learn THAT stuff.  I want to |
| 01:53.34 | SpeedEvil | get my master's degree so I can become a full-time college professor when I'm |
| 01:53.34 | SpeedEvil | ready to retire from programming.  I want to write multiple books.  I want to |
| 01:53.34 | SpeedEvil | start a third convention so I have an excuse to wave the Cartoon Guide to |
| 01:53.34 | SpeedEvil | Federal Spectrum Policy at people' |
| 01:53.45 | SpeedEvil | Basically true for me too. |
| 01:53.54 | SpeedEvil | (though not those items) |
| 01:54.22 | Mirell | Yah, landley's been wanting to get his Master's since I've known him, and has tried...three times I believe? |
| 01:54.33 | Mirell | And I've known him eight years or so. |

| 01:55.16 | SpeedEvil | Oh - he's here. |
| 01:55.24 | SpeedEvil | Rant I largely agree with. |
| 01:55.30 | Mirell | I think the first time was because the Education curriculum was horrid. |
| 01:55.36 | roxfan | i like all the "somebody needs to <do stuff>" |
| 01:55.37 | SpeedEvil | tiny linux would be cool. |
| 01:55.45 | Mirell | And the second time was because they were teaching horrible outdated database concepts. |
| 01:55.52 | solar | those asm utils? |
| 01:56.02 | SpeedEvil | solar - no. |
| 01:56.17 | SpeedEvil | solar: Totally rewriting the linux kernel to start out with a small base. |
| 01:56.37 | solar | a total rewrite would not be linux :p |
| 01:56.44 | SpeedEvil | solar: So you can - if you want to - utterly omit large chunks of 'core' stuff. |
| 01:56.46 | Mirell | linux-ng |
| 01:57.02 | Mirell | There's already a precedent. |
| 01:57.03 | solar | SpeedEvil: oh the tiny patches.. |
| 01:57.03 | SpeedEvil | solar: Compare linux 2.6 to 1.0 |
| 01:57.13 | SpeedEvil | solar: no - not the tiny patches |
| 01:57.14 | solar | 2.6 to 2.4 even.. |
| 01:57.26 | SpeedEvil | solar: you can only go so far by trying to disable stuff. |
| 01:57.41 | SpeedEvil | At some point you've got to go back through it, not enabling stuff. |

| 02:00.00 | solar | the solution is quite simple. Use an older kernel and backport the drivers you need |
| 02:00.47 | landley | Getting a current kernel properly modular would be nice. |
| 02:01.09 | landley | Hello world and work up... |
| 02:01.59 | solar | to what? serial |
| 02:03.11 | SpeedEvil | See the above link solar. |

| 02:04.10 | solar | yeah. softkeys blow. |
| 02:04.16 | SpeedEvil | On a random point - does anyone happen to know what populates /proc/timer_stats - I started to try to work through the callchain, then I got stuck. |

| 02:06.05 | SpeedEvil | I suppose I should retry reading it |
| 02:16.12 | rue_mohr | solar, yea, I know the bootloader has a way of interrupt ing it for doing uploads etc, can I get an image of the flash contents before I mess with them? |
| 02:16.22 | rue_mohr | I suppose as long as I dont nail the bootloader I'm ok |
| 02:16.34 | rue_mohr | I dont know if the new kernel 'fits' |
| 02:16.41 | rue_mohr | hows the limit go? |

| 02:37.57 | landley | I'm gonna plead the fifth. |
| 02:38.23 | wmat | SpeedEvil: all you need is a 3 foot piece of garden hose to siphon it all out |
| 02:38.37 | SpeedEvil | anti-siphon features in the tank. |
| 02:38.58 | landley | rue_mohr The ledenfrost effect. Mirell can tell you about that. :) |
| 02:38.58 | SpeedEvil | tried that with hose, and with aquarium tubing. |
| 02:39.07 | wmat | bummer |
| 02:39.18 | rue_mohr | SpeedEvil, why not tap the fuel line under the hood, and get the fuel pump to give you it all |
| 02:39.38 | SpeedEvil | rue_mohr: Because the hood opener is broken, and I'm trying to work out how to fix that. |
| 02:39.47 | rue_mohr | you can change your fuel filter in the process |
| 02:40.09 | rue_mohr | I see, this IS your car yes? |
| 02:40.12 | SpeedEvil | yes |
| 02:40.17 | rue_mohr | what kinda car |
| 02:40.24 | SpeedEvil | Renault Laguna. |
| 02:40.48 | rue_mohr | stares blankly forward |
| 02:40.56 | rue_mohr | uh, a what? |
| 02:41.39 | wmat | http://en.wikipedia.org/wiki/Renault_Laguna |
| 02:41.47 | SpeedEvil | yeah |
| 02:41.55 | SpeedEvil | IIRC 94 |
| 02:41.58 | rue_mohr | ok |
| 02:42.11 | rue_mohr | so do they use a pull cable from the hood to the opener? |
| 02:42.24 | rue_mohr | handle thing |
| 02:42.32 | rue_mohr | wait, this is't #robotics.... |
| 02:42.57 | SpeedEvil | yes - they do. I think it broke at the hood end - which complicates things. |
| 02:43.03 | rue_mohr | SpeedEvil, your not in any of the channels your supposed to be in |
| 02:43.16 | SpeedEvil | ? |
| 02:43.28 | rue_mohr | see, this wouldn't even be off topic in #robotics cause its a mechanical conversation |
| 02:43.34 | SpeedEvil | :) |
| 02:43.46 | rue_mohr | right ok, whatever |
| 02:44.06 | rue_mohr | just make sure we finish with your engine managment computer running linux and were ok |
| 02:44.15 | SpeedEvil | Actually - not. |
| 02:44.19 | SpeedEvil | The ECU is broken. |
| 02:44.28 | wmat | SpeedEvil: http://www.questionhub.com/YahooAnswers/20090925122000AAL1Shd |
| 02:44.29 | SpeedEvil | I have a megasquirt I need to solder up. |
| 02:44.29 | rue_mohr | wait, what DOES work on this car? |
| 02:44.37 | rue_mohr | SpeedEvil, oooo |
| 02:44.43 | rue_mohr | you know of robert heibert? |
| 02:44.49 | SpeedEvil | nope |
| 02:44.51 | rue_mohr | oh |
| 02:45.06 | rue_mohr | thought he contributed enough everyone would have known him |
| 02:45.09 | rue_mohr | oh well |
| 02:45.30 | rue_mohr | he made a automatic transmissoin controller based from megasquirt |
| 02:45.36 | rue_mohr | iirc megashift |
| 02:45.37 | rue_mohr | :) |
| 02:45.38 | SpeedEvil | Neat. |
| 02:45.46 | rue_mohr | it was a long time ago now |
| 02:45.59 | SpeedEvil | I pondered a manual gearbox controller. |
| 02:46.04 | rue_mohr | iirc, he's working on porting the new version to his hardware |
| 02:46.10 | rue_mohr | yea |
| 02:46.17 | rue_mohr | he has a joystick he shifts with |
| 02:46.34 | rue_mohr | SpeedEvil, you didn't asnwer |
| 02:46.37 | SpeedEvil | I mean - a controller to improve shifts on a manual gearbox. |
| 02:46.40 | rue_mohr | what DOES work on this car? |
| 02:46.43 | SpeedEvil | ah |
| 02:46.53 | SpeedEvil | well - as it's got no working ECU - very little |
| 02:47.18 | rue_mohr | from what I gather, the fuel tank holds fuel and the hood latch keeps the hood firmly down |
| 02:47.31 | SpeedEvil | Or rather - I believe the ECU to work, but to require either rekeying, or repplacement of the IR pod, and re-keying of the ECU with new keys. |
| 02:47.40 | rue_mohr | you cant get into the grill on there with a screwdriver and pry over the release lever? |
| 02:47.42 | SpeedEvil | Which would exceed the value of hte car |
| 02:48.09 | rue_mohr | so how did this car die? |
| 02:48.12 | SpeedEvil | yeah - I can't seem to get that to work - I'm unsure why - next I cut away part of the grill, and insert camera, so I can see. |
| 02:48.16 | rue_mohr | the engine just quit on you? |
| 02:48.23 | SpeedEvil | I drove it home. It did not restart. |
| 02:48.42 | rue_mohr | how long has the hood lever been broken? |
| 02:48.49 | SpeedEvil | At least 6 months |
| 02:49.01 | rue_mohr | ah |
| 02:49.33 | rue_mohr | so the cable gave out at the hood latch? |
| 02:49.47 | SpeedEvil | I think so. |
| 02:50.12 | SpeedEvil | Going to go in through the grill I think. |
| 02:50.17 | rue_mohr | yea |

| 19:33.05 | landley | Hexagon isn't arm. It's a new chip that beats arm's power/performance ratio with clever parallelism tricks. |
| 19:33.18 | landley | New instruction set. |
| 19:33.25 | chouimat | not another one |
| 19:34.57 | landley | It's already out in the field. The multimedia coprocessor in the nexus and inedible that handles video playback and mp3 decoding and such? |

| 19:35.01 | prpplague | landley: ahh interesting, now i understand why they have you onboard |
| 19:36.07 | landley | In android, the snapdragon SOC has an arm and a hexagon (and some other stuff) |
| 19:36.17 | prpplague | ahh interesting |
| 19:36.49 | landley | The arm is running Linux, the hexagon's running binary blob firmware. |
| 19:37.13 | landley | But no reason you can't run linux on hexagon directly. |
| 19:37.19 | chouimat | i see coprocessor/dsp kind of stuff |
| 19:37.26 | landley | It's a 6-way smp. |
| 19:37.57 | landley | Started life as a dsp. Development name was qdsp6. |
| 19:38.54 | landley | Sort of a dsp that grew legs. |
| 19:39.49 | landley | You can devote processor threads to realtime tasks under linux no problem, so having it run linux doesn't stop it from doing realtime multimedia stuff too... |
| 19:40.06 | chouimat | landley: sound like the cell processor (in a way) |
| 19:41.41 | landley | Only shipping now, and it's smp not amp. |
| 19:41.50 | landley | You program all 6 using same instruction set. |
| 19:42.23 | landley | No weird memory models or different programming models. |
