| bluefoxicy | hey guys, question, has anyone taken note of the new stuff in DRM in 2.6.16? The 2.6.15 kernel in Dapper as of 1 month ago still crashed due to bugs in the via DRM code if using the X driver "via" | 09:32 |
| bluefoxicy | I'm about to try building a 2.6.16 kernel and test the via driver against that in current Ubuntu (AMD64 K8) kernel to see if it appears stable | 09:33 |
| crimsun | is it backportable to our current source? | 09:33 |
| bluefoxicy | crimsun: I am not sure, I have doubts though. I glanced through the 2.6.16 patch from 2.6.15, there's a large amount of extra code in DRM, some in the drm_dma and drm_mm code, so I'm guessing DRM got a slight rework? | 09:34 |
| bluefoxicy | crimsun: backporting it would be nice though | 09:34 |
| mjg59 | bluefoxicy: How can you tell it's a DRM bug? | 09:34 |
| mjg59 | Can we have a bug number? | 09:34 |
| bluefoxicy | https://launchpad.net/distros/ubuntu/+source/linux-source-2.6.15/+bug/29586 | 09:34 |
| bluefoxicy | mjg59: my biggest hint was the system hard-hanging after several complaints (Oopses) from the kernel if I use Driver "via" in Xorg.conf, which goes away if I use Driver "vesa" | 09:35 |
| mjg59 | bluefoxicy: That's still quite possibly an issue on the X side | 09:35 |
| bluefoxicy | average uptime is an hour with the via driver, days or weeks with vesa; and the oopses come up in the via code | 09:35 |
| mjg59 | (well, the mesa side) | 09:35 |
| bluefoxicy | mjg59: X should be able to trash kernel space? | 09:35 |
| mjg59 | bluefoxicy: Not really, and it does indicate that there's some issue with the drm code. But that's not necssarily what's causing the hangs | 09:36 |
| mjg59 | "via driver is shit" certainly wouldn't be news | 09:36 |
| bluefoxicy | Feb 23 07:52:06 localhost kernel: [33790.181303] <1>Unable to handle kernel paging request at 0000000005fdc288 RIP: | 09:37 |
| bluefoxicy | Feb 23 07:52:06 localhost kernel: [33790.187430] <ffffffff88440e6a>{:via:via_mmFreeMem+10} | 09:37 |
| bluefoxicy | mjg59: *shrug* I dunno then. | 09:37 |
| bluefoxicy | I always assumed trashing the kernel's memory space would need to happen in the kernel. | 09:38 |
| mjg59 | The kernel's memory space is not necessarily trashed | 09:38 |
| mjg59 | It may just be trusting user input (stupid, but, well) | 09:38 |
| mjg59 | The irq backtrace in the last comment is entirely unrelated | 09:38 |
| bluefoxicy | yes, yes it is. | 09:38 |
| bluefoxicy | I threw 'irqpoll' into the kernel command line | 09:39 |
| bluefoxicy | failed to boot | 09:39 |
| mjg59 | Ah. Now, there /is/ a 64-bit related bug | 09:40 |
| mjg59 | Can you grab the ubuntu kernel source and apply the patch from http://webcvs.freedesktop.org/dri/drm/shared-core/via_mm.c?r1=1.21&r2=1.22&makepatch=1&diff_format=u ? | 09:41 |
| bluefoxicy | mjg59: ah, yay, no need to do a full move to 2.6.16? :) | 09:43 |
| bluefoxicy | mjg59: int != long on 64 bit? | 09:44 |
| Mithrandir | bluefoxicy: correct | 09:44 |
| bluefoxicy | time to replace my gints with glongs | 09:44 |
| Mithrandir | just store pointer types in pointers and ints in ints and you're fine. | 09:44 |
| bluefoxicy | mjg59: how do I build this thing? I don't feel like manually configuring it (I've done that enough times while running gentoO) | 09:46 |
| mjg59 | bluefoxicy: dpkg-buildpackage -rfakeroot -nc | 09:46 |
| mjg59 | delete all the config.something files in debian/config/amd64/ so you just have config and config.whatever | 09:47 |
| mjg59 | Otherwise you'll build loads of images | 09:47 |
| bluefoxicy | there's no debian directory. | 09:50 |
| mjg59 | What source did you get? | 09:52 |
| bluefoxicy | linux-source-2.6.15 | 09:52 |
| mjg59 | How? | 09:52 |
| bluefoxicy | via apt-get | 09:53 |
| bluefoxicy | and then bzcat | tar x on the file it put in /usr/src | 09:53 |
| mjg59 | Do apt-get source linux-image-whatever | 09:53 |
| bluefoxicy | apt-get build-something .. uh | 09:58 |
| bluefoxicy | builddep? | 09:58 |
| bluefoxicy | drivers/ide/ide-acpi.c:537: warning: format %x expects type unsigned int, but argument 4 has type long unsigned int | 10:08 |
| mjg59 | Ignore | 10:08 |
| mjg59 | Fixed in the next release | 10:08 |
| bluefoxicy | alright. | 10:08 |
| bluefoxicy | arch/x86_64/pci/mmconfig.c:49: warning: return makes pointer from integer without a cast | 10:09 |
| bluefoxicy | It just makes me wonder | 10:09 |
| bluefoxicy | do you think anyone actually knows the fundamental difference between a warning and an error? | 10:10 |
| bluefoxicy | mjg59: Once this is compiled I'll need about 6 hours to be sure it's actually working. The bug is probabilistic; depending on what's going on I'll have problems, but I can view movies and switch desktops without a problem for a while. Usually what kills me is wandering away from the machine and letting the screensaver come on ;) | 10:12 |
| bluefoxicy | and usually within an hour of running, though I've had it stay up all day once or twice before I realized what the problem was. | 10:13 |
| bluefoxicy | it's stupid, I don't have a button marked "Crash System" to press | 10:13 |

| m_tadeu | I think there's a problem with the kernel/nforce chipsets | 10:50 |

| m_tadeu | where can i find that? | 11:19 |
| bluefoxicy | mjg59: Okay, it still bitched about the IRQ but that's immaterial. The question is, can I hammer it and not die | 11:20 |
| bluefoxicy | mjg59: bluefox@icebox:~$ glxgears | 11:20 |

| bluefoxicy | mjg59: any ideas on this one yet? | 11:20 |
| m_tadeu | bluefoxicy, where can i find that kernel packge? | 11:22 |
| bluefoxicy | m_tadeu: what package? | 11:22 |
| bluefoxicy | m_tadeu: the one I'm using I just built | 11:22 |
| bluefoxicy | from a source package in dapper | 11:22 |
| m_tadeu | bluefoxicy, sory :) though that was for me :) | 11:24 |
| mjg59 | bluefoxicy: Uh. Are you using the via driver or the vesa one? | 11:31 |
| bluefoxicy | via | 11:32 |
| mjg59 | Check dmesg? | 11:32 |
| bluefoxicy | it's fine so far. | 11:34 |
| bluefoxicy | mjg59: the double buffer thing always happens. | 11:34 |
| mjg59 | Oh, right. Dunno, then | 11:34 |
| bluefoxicy | https://launchpad.net/distros/ubuntu/+source/xserver-xorg-driver-ati/+bug/29493 It's like this one | 11:36 |
