| dilinger | BenC: libata supports smart ioctls? as of when? | 12:13 |
|---|---|---|
| dilinger | also, has anyone done any reverse engineering of win32 drivers? what do people recommend for disassembly (and if something exists, decompilation to something resembling C) | 12:14 |

| BenC | dilinger: libata passthrough patch went in during last month of breezy | 12:28 |
| infinity | BenC : I'll fiddle with initramfs and the above-mentioned libata modprobe argument, since I'm one of the people who whined about his disappearing CDROM. | 12:33 |
| infinity | (The resource conflict with ide-generic thing is a red herring, BTW, 2.6.12 gave the same output. It's the 5 or 6 lines BEFORE that that went missing that are important) | 12:34 |
| infinity | Of course, given our focus as a desktop OS, it may be in our best interest to just hack our kernels to always turn that flag on in the driver, and not mess with it in initramfs. | 12:35 |
| infinity | (We can revisit that the day someone complains that ATAPI is always on) | 12:36 |
| dilinger | BenC: oh | 12:56 |
| dilinger | BenC: you mean went into breezy or upstream? | 12:57 |
| === dilinger is using a backported debian 2.6.12 at work, no libata smart ioctl passthrough there | ||
| dilinger | but i haven't tested the amd64 breezy machine i just installed | 12:57 |
| BenC | infinity: that's what I'm thinking too | 01:05 |
| BenC | dilinger: breezy, it's in 2.6.15 | 01:06 |
| infinity | BenC : Well, I'll do some quick reboot testing and verify that this really does bring my drive back from the dead, and if so, we can decide which direction to go with it. | 01:11 |
| infinity | I assume it'll work, though. | 01:11 |
| BenC | infinity: worked for a guy on kernel-team list | 01:11 |
| === ispiked [n=ispiked@nom3817it.nomadic.ncsu.edu] has joined #ubuntu-kernel | ||
| BenC | I'm trying to catch jgarzik to see how stable the sata atapi code is right now | 01:12 |
| infinity | Oh, you've already pinged him with the fix? I only saw his message with dmesg output, etc... Nothing else. | 01:12 |
| infinity | The only danger seems to be in having libata drive really old PATA ATAPI devices over an SATA->PATA bridge, which seems a pretty unlikely combination to me. | 01:13 |
| BenC | yeah, I redid my email client, and got moderated to the list | 01:23 |
| BenC | but he got my email and replied | 01:23 |
| infinity | Ahh, cool. | 01:26 |
| BenC | jgarzik says sata_promise and sata_sx4 are known to not work with atapi | 01:29 |
| BenC | the drivers that is | 01:29 |
| infinity | Well, that sort of leaves us at an impasse. | 01:30 |
| BenC | I'm going to blacklist those two drivers and set atapi_enabled=1 by default | 01:30 |
| infinity | Those two drivers are kinda popular. :/ | 01:30 |
| infinity | (not as popular as piix or via but still) | 01:30 |
| mjg59 | infinity: I've found various drivers that probably ought to be in l-r-m | 01:49 |
| infinity | You mean stuff that should be removed from the kernel, or stuff we don't yet ship? | 01:50 |
| infinity | (speaking of the latter, I need to make ltmodem build again) | 01:50 |
| mjg59 | infinity: Stuff we don't yet ship | 01:50 |
| mjg59 | Modem drivers (hahaha) | 01:51 |
| infinity | Mmkay. | 01:51 |
| infinity | More ltmodem-like crap? | 01:51 |
| mjg59 | Intel ones for a start | 01:51 |
| infinity | Why can't we just finance a worldwide effort to get broadband to everyone's house? | 01:51 |
| mjg59 | There's one for the 536 and one for the 537 | 01:51 |
| mjg59 | The 537 one looks like it needs light hacking to get it to work on recent 2.6, the 536 one looks ok | 01:52 |
| mjg59 | But they're both 2.6 compatible | 01:52 |
| infinity | You do the light hacking required, and I'll happily include them. | 01:52 |
| mjg59 | I'm also looking at the old (GPLed) Conexant drivers | 01:52 |
| mjg59 | They involve rather more pain | 01:52 |
| infinity | I want, bsically, upstream tarball, + your patches in a diff. | 01:52 |
| mjg59 | Oh, when I say GPLed, I mean "GPL + closed shit" | 01:53 |
| infinity | The conexant stuff looked scary. | 01:53 |
| mjg59 | The conexant stuff scares the shit out of me | 01:53 |
| mjg59 | I'm trying to forward port the last release of it to 2.6 | 01:53 |
| mjg59 | Sorry, the last free release | 01:53 |
| mjg59 | It still looks scary, but, well | 01:53 |
| infinity | We don't even attempt to support modems/ppp in d-i as a network method, right? | 01:54 |
| mjg59 | Nope | 01:54 |
| infinity | So these don't need to hit a udeb, just the main LRM deb... | 01:54 |
| infinity | Good. | 01:54 |
| infinity | Well, if you make the intel stuff work and I make the ltmodem stuff work, we've suddenly got coverage of a crapload of softmodems. The conexant stuff would be a nice bonus, though. | 01:56 |
| === ispiked [n=ispiked@nom3809it.nomadic.ncsu.edu] has joined #ubuntu-kernel | ||
| infinity | Personal anecdotal statistical analysis, and some really bad math would lead me to eblieve that 8 out of 5 people have an LT-based softmodem somewhere in their house. | 01:57 |
| mjg59 | Yeah | 01:58 |
| mjg59 | I've got at least one | 01:58 |
| mjg59 | Most of them are slmodem-compatible now, though | 01:58 |
| infinity | Of course, I haven't actually used a modem in Linux since, like, 1995. | 02:01 |
| infinity | Perhaps this makes me an ideal candidate to test this stuff and see if it's foolproof. | 02:02 |
| mjg59 | Modern hardware is almost all AC97. Of that, pretty much everything uses a smartlink-compatible codec except for ones which use Conexants | 02:03 |
| mjg59 | Oh, and Apples, which use some horrid USB conexant thing | 02:03 |
| infinity | Well, enough people have complained about ltmodem going away that I assume someone still needs it. | 02:03 |
| infinity | Anyhow, a fork that builds on moden kernels has been pointed out to me, so I'll re-enable it and close the bugs, and not care much about the particulars. :) | 02:04 |
| infinity | Whatever you want in LRM, though, just get me upstreamish source (with an upstream URL of sorts), plus your patches to make it function, and I'll integrate it. | 02:06 |
| infinity | And make sure we can distribute it, of course. | 02:06 |
| mjg59 | Oh, sure | 02:20 |
| infinity | BenC : Kay, just tested with "break=premount && modprobe libata atapi_enabled=1 && exit", and the resulting boot had my CD/DVD drive too. Yay. | 02:42 |
| infinity | Of course, I still don't have a /dev/dvd, but that's probably something I can blame on Keybuk. | 02:44 |
| infinity | Hrm. | 02:52 |
| infinity | WEEKEND OFFTOPIC QUESTION: | 02:53 |
| infinity | Does anyone know how to force my DVD drive (or software player) to pretend to be in a specific region? | 02:53 |
| infinity | (Rather than doing auto-region, region-guessing, which breaks on Star Wars DVDs which try multiple regions and bomb out if more than 1 is found to be "valid") | 02:54 |
| mjg59 | infinity: Your player should have an option to force the region | 02:59 |
| mjg59 | Then it can just lie to the DVD | 02:59 |
| infinity | Don't see one in mplayer's manpage, and xine's doesn't appear to actually do anything. Yay. | 02:59 |
| mjg59 | Hm. Getting the hcfusbmodem driver working ought to be practical | 02:59 |
| mjg59 | Which ought to mean working Apple modems. Yay. | 02:59 |
| infinity | Oo, more stuff for powerpc LRM users?... Fun. | 03:00 |
| mjg59 | The hacking in most of it is fairly easy, but it'll need a bit of reconstructive work in the serial layer | 03:00 |
| mjg59 | And then, with luck, that'll be applicable to the hsf code as well | 03:00 |
| mjg59 | Only real problem is that we'll be running with older Conexant code | 03:00 |
| mjg59 | Oh, and all these drivers want to spew huge gobs of stuff across / | 03:01 |
| mjg59 | Need to look into minimising that | 03:01 |
| infinity | Ahh, well, hard-setting the region on the drive helped at any rate. | 03:08 |
| BenC | infinity: cool | 03:35 |

| mjg59 | BenC: If we're switching on the PATA libata stuff, should we switch on ata_piix's PATA support? | 05:42 |
| BenC | I'll check it, it may be on from the merge I did with libata-dev.git | 05:43 |
| BenC | infinity: pong | 05:44 |
| mjg59 | BenC: It's a single #define in ata_piix.c, IIRC | 05:47 |
| BenC | yeah, I see it | 05:47 |
| AcidPils1 | ah, BenC siretart told me to ask you about the missing acx module in the 1.6.15 kernel | 05:47 |
| AcidPils1 | bug or feature? | 05:47 |
| BenC | I'm not really enabling PATA except where there are PATA drivers | 05:47 |
| AcidPils1 | 1.6.15? 2.6.15 i mean ;) | 05:47 |
| BenC | acid: what is the acx module? | 05:47 |
| AcidPils1 | drivers for acx100/acx111 wlan cards | 05:48 |
| AcidPils1 | in 2.6.12 they were included, but in 2.6.15 they are not | 05:49 |
| BenC | acidpils: uh, it is enabled | 05:50 |
| BenC | check the config, CONFIG_ACX100=m | 05:51 |
| BenC | mjg59: let me talk to jgarzik about how safe PATA is in that driver (atiix and one other, are the only ones that need the define to enable PATA) | 05:52 |
| BenC | everything else is just on | 05:52 |
| mjg59 | BenC: If we could get that and the SATA hotswap patches, then I can whip up support for swapping bay devices on laptops | 05:54 |
| mjg59 | It's a small amount of acpi-integration code | 05:54 |
| BenC | what exactly is PATA anyway (how's it different from SATA)? | 05:55 |
| mjg59 | Parallel ATA | 05:55 |
| mjg59 | Or legacy stuff | 05:55 |
| mjg59 | The ones with 40 or 80-wire cables | 05:55 |
| BenC | ah | 05:56 |
| Yagisan | the "though cables must be shorter then ~80cm or it won't work" version | 05:58 |
| AcidPils1 | BenC: i must have been blind or something like that | 05:59 |
| AcidPils1 | *reboot and try* | 05:59 |
| siretart | oh nice.. my r50e is Oopsing on power down.. grml.. | 06:00 |
| BenC | 80cm? Who runs > 80cm cables to their drives? | 06:02 |
| BenC | or did you mean 8cm? :) | 06:02 |
| mjg59 | 18" | 06:02 |
| mjg59 | So 50cm | 06:02 |
| mjg59 | On x86 boards, it's quite common | 06:02 |
| BenC | ok, 18" makes more sense | 06:02 |
| Yagisan | BenC: I have a full tower case here, and due to design error, the PATA cable and drives are on opposite sides of the case | 06:03 |
| Yagisan | BenC: funnily enough there are a lot of pcs with pata cables up to 1m long in them (and I wonder how they still work) | 06:05 |
| Yagisan | any chance of the swap prefetch patch from http://ck.kolivas.org/patches/swap-prefetch/mm-swap_prefetch-18.patch ? | 06:11 |
| BenC | I'll let that stuff simmer in -mm first | 06:12 |
| Yagisan | OK, couldn't hurt asking. Thanks BenC | 06:13 |
| BenC | np | 06:15 |

| siretart | BenC: I checked the build logs, and AcidPils seems to have a point somewhere. Despite of being enabled in the kernel config, it seems that the kernel module acx_pci.ko is not built any longer. | 07:07 |
| siretart | so either it has moved to another kernel module, or it vanished somehow.. | 07:08 |
