| infinity | lamont : Feh, if 'linux32 uname -m' on parisc64 is returning parisc64, not parisc, then parisc64 personalities are broken. I was almost sure that had been addressed long ago, but maybe not (I never owned a parisc64 machine, so this was all from memory) | 04:13 |
|---|---|---|
| infinity | My parisc machine was a lowly 32-bit C200. | 04:13 |
| infinity | lamont : Pretty please, with sugar on top, pester linux-parisc upstream to fix 32/64 kernel personalities, push the patch upstream, and use that patch on your buildd. :) | 04:17 |
| lamont | infinity: parisc _ALWAYS_ returns parisc64 | 04:17 |
| lamont | always has (on a 64-bit kernel_) | 04:17 |
| infinity | No it doesn't. Only when running a parisc64 kernel. | 04:17 |
| lamont | that's what I said. :-) | 04:17 |
| infinity | Anyhow, it's broken. It shouldn't. That's what personalities are for (it's ALL they're for) | 04:17 |
| infinity | We just got it fixed for ppc/ppc64 in 2.6.12, now it's your turn. :) | 04:18 |
| lamont | yeah - jbailey's going to beat on the parisc folks, but in the mean time, we'll just do the hack to klibc that has been done everywhere else | 04:18 |
| infinity | <nod> | 04:18 |
| infinity | I assume you had line-of-sight (and perhaps line-of-office-supply-tossing) with some parisc kernel guys. | 04:19 |
| infinity | s/assume/assumed/ | 04:19 |
| lamont | well... certainly when I have a mirror... | 04:19 |
| lamont | but the issue here is talking to the folks that did the implementation, and figuring out what it really should be saying when. | 04:20 |
| infinity | If so, tell them to search lkml for ppc64 and uname over the last 4 or 5 months. Should tell them what to fix. :) | 04:20 |
| lamont | and it's not something to change right now... | 04:20 |
| infinity | (I could provide a patch, but have no way to test anything) | 04:20 |
| lamont | esp since we can't build/install the new (fixed) ubuntu kernel until we have a working klibc... | 04:20 |
| === infinity wonders idly if this is also broken on s390/s390x.. | ||
| lamont | jbailey wondered the same thing, and ran away screaming at 31-bit worlds | 04:22 |
| lamont | or something like taht | 04:22 |
| infinity | I think arm/arm64 is okay. | 04:22 |
| infinity | Yeah, I don't think s390 would bother with a "linux31" binary, they'd just pretend to be 32-bit and carry on. :) | 04:22 |
| jbailey | infinity: The fix is almost tribial, but not quite. | 04:23 |
| jbailey | infinity: They use the personality to change how they handle signals internally. | 04:23 |
| jbailey | It's almost certainly not what they meant. | 04:23 |
| infinity | Oh, FUN. | 04:23 |
| jbailey | I think I have it mapped out as to what needs to change. | 04:23 |
| jbailey | I'm going to sleep on it and do it then. I have klibc for lamont already. | 04:23 |
| jbailey | Just need to hand it to fabio, and then I think that's done for breezy. | 04:24 |
| jbailey | (unless someone comes up with another !@#$ing filesystem they want to use as a root one) | 04:24 |
| === lamont mutters about big kernel changes right before release... | ||
| infinity | Well, there's no docs (afaik) saying you can't extend the use of personalities to do other neat hacks/tricks, just what they SHOULD do (fool userspace into believing you're on a 32/64 bit kernel when you're not) | 04:24 |
| lamont | oh, klibc, not the kernel. | 04:24 |
| lamont | nm | 04:24 |
| jbailey | infinity: What they've done in this case is assume that a 32 bit binary means you want a 32 bit personality. | 04:25 |
| jbailey | infinity: I think. I'm having trouble tracing some of this code. =) | 04:25 |
| infinity | That's possibly reasonable. | 04:25 |
| === lamont waits for his 2.4-kernel-possessing knoppix 3.7 ISO to burn, then he's gonna reboot and head home | ||
| jbailey | It's not how sparc and ppc do it. | 04:25 |
| infinity | But they're still not munging uname output, which is the issue. | 04:25 |
| infinity | No, it's not what sparc and ppc do in the slightest, but it seems a valid extension to the use of personalities. | 04:26 |
| jbailey | sparc and ppc set a threadinfo variable with the info. | 04:26 |
| jbailey | Which frightens me to think that they might have PER THREAD shit^Wstuff going on. | 04:26 |
| infinity | I suppose this is where I start being greatful that Motorola never announced a 68k-64 CPU. | 04:26 |
| jbailey | infinity: Probably. a 4 mhz 64 bit CPU would really suck for data loads. | 04:27 |
| lamont | hehe | 04:27 |
| infinity | <grin> | 04:27 |
| lamont | 64-bit 8051 | 04:27 |
| jbailey | I still like the idea of just runnign the whole m68k buildd in a nice emulated environment on a large ia64 machine. | 04:28 |
| infinity | Hey, if they opened up the specs, any goober with access to fab flipchips could get the 68060 scaled ridiculously high, I'm sure. | 04:28 |
| infinity | It's just that Motorola never upgraded their fabrication, ever. New ones are still the old ceramic things you can clock peopl ein the head with. | 04:28 |
| jbailey | Why should they, really? If you wanted a small 32 bit chip, the i386 is good enough. | 04:28 |
| jbailey | Last I checked they were still producing those by the assload. | 04:29 |
| infinity | <nod> | 04:29 |
| infinity | Well, Motorola still produces 68k stuff by the assload too, just not the desktop chips. | 04:29 |
| jbailey | YEah, they still have the embedded medical market. | 04:29 |
| infinity | The more popular all-in-one stuff with fancy multimedia controllers and such (but, oddly, no MMU) are in high production still. | 04:29 |
| lamont | well, I'm off | 04:30 |
| jbailey | g'n LaMont | 04:30 |
| infinity | Later. | 04:30 |
| jbailey | infinity: The other reason in particular that magic isn't a good idea is that it means that all 32 bit binaries would always report parisc from newuname | 04:38 |
| infinity | Yes, including a 32-bit 'linux64' binary. | 04:45 |
| infinity | That would definitely seem wrong. | 04:45 |
