@Chonnawonga With the 2.6.22-14-generic kernel, no patch or module renaming is needed on my machine. The AGP aperture size is recognized correctly and direct rendering works with no modifications. Both amd64-agp and the stock, unmodified version of sis-agp are loaded. The only problem I experience is the APIC error discussed above. This error does not seem to have any bad effects other than filling up the logs, though. I've experienced no other problems, even with desktop effects enabled. I can't comment on power management.

I'd just like to confirm, I have the same bug, using the same motherboard (K8S-MX). I can get the AGP aperture to identify correctly, and allow direct rendering, by renaming (i.e. disabling) sis-agp.ko, but that breaks my power management. Sybille, if I rename sis-agp.ko back to its original name and apply your patch, will that fix my power management without breaking direct rendering again?

[Bug 34144] Re: sis 760 AGP broken on amd64
I had a chance to experiment with things some, and I think I made a little progress. I was doing this on a Gentoo system with a 2.6.22 kernel compiled from gentoo-sources, but I don't think that makes a difference. Although this is amd64 hardware, I'm using an x86 kernel/OS. As I mentioned in the a href=https://bugs.freedesktop.org/show_bug.cgi?id=8840freedesktop bug/a, it seems to me that incorrect identification of the AGP aperture size as 4M no matter what the BIOS setting is related to the SIS 760 device IDs in the sis-agp module of the kernel. If that is the case, then it should be possible to comment out the device IDs and recompile the module in order to see how the aperture size is identified. I had tried to do this before and apparently made some mistakes, but this time I did things correctly. Because, when I booted using the modified sis-agp module, I saw the following in the syslog: Oct 31 10:00:31 menagerie agpgart: Detected AGP bridge 0 Oct 31 10:00:31 menagerie agpgart: AGP aperture is 128M @ 0xf000 Compare this with the unaltered kernel module: [ 102.351910] agpgart: Detected SiS 760 chipset [ 102.352228] agpgart: AGP aperture is 4M @ 0xf000 128M is the BIOS setting. I've attached a patch to show what I changed in the sis-agp module to get the above result. Unfortunately, however, using this altered module did not solve the APIC error problem. That is, with the altered sis-agp module and amd64-agp loaded, the AGP aperture size was identified correctly during boot, DRI was enabled, but the stream of APIC errors began once the drm module was loaded. So it's not really a patch that solves things for me, just some more information that I thought might be useful. @Neil Wilson, I'm using the most recent beta BIOS for my motherboard (asus k8s-mx). I've upgraded the BIOS twice since opening this bug, with no effect on the problem. Regarding the noapic boot option, I've used that too but found it a problematic workaround. For me, it leads to IRQ problems such as: Oct 31 06:04:20 menagerie irq 7: nobody cared (try booting with the irqpoll option) Oct 31 06:04:20 menagerie [c0148be4] __report_bad_irq+0x24/0x80 Oct 31 06:04:20 menagerie [c0148e91] note_interrupt+0x251/0x280 Oct 31 06:04:20 menagerie [c0148115] handle_IRQ_event+0x25/0x50 Oct 31 06:04:20 menagerie [c014987d] handle_level_irq+0xcd/0x110 Oct 31 06:04:20 menagerie [c010672e] do_IRQ+0x3e/0x80 Oct 31 06:04:20 menagerie [c010498f] common_interrupt+0x23/0x28 Oct 31 06:04:20 menagerie [c0102b3a] default_idle+0x2a/0x40 Oct 31 06:04:20 menagerie [c01023e3] cpu_idle+0x43/0x80 Oct 31 06:04:20 menagerie [c0462b2f] start_kernel+0x21f/0x2b0 Oct 31 06:04:20 menagerie [c0462450] unknown_bootoption+0x0/0x260 Oct 31 06:04:20 menagerie === Oct 31 06:04:20 menagerie handlers: Oct 31 06:04:20 menagerie [c02ddf50] (usb_hcd_irq+0x0/0x60) Oct 31 06:04:20 menagerie Disabling IRQ #7 And that is accompanied by the whole system freezing. Again, this is only when using noapic at boot. The mother board I'm using is kind of strange because it has both an AGP slot and a PCI Express slot (1x), maybe that's part of the issue. I don't have anything plugged into the PCIe slot, though. In any case, I believe that my experiment with the device IDs suggests that the issue is with the kernel module. And I notice that the AGP kernel maintainer, Dave Airlie, has already responded to this bug, so... In any case, there is now some evidence that there is a regression here as far as the SIS AGP driver is concerned and that it is not a matter of BIOS setting or updates.

[Bug 34144] Re: sis 760 AGP broken on amd64
@Neil Wilson Hi, We only took the route of deleting the module because I'm using a LiveCD and so could not blacklist and reboot with that change saved. It's just a workaround because I don't have an Ubuntu install at present (although I will install if needed). At this point, I think there are two problems. Problem 1: If both the amd64_agp and the sis_agp drivers are loaded, then there is a conflict that prevents the size of the agp aperture from being identified correctly (4M rather than the setting in the BIOS, which is 128M for me); dri is not enabled. Problem 2: If only the amd64_agp driver is used, then dri works too, BUT the system also produces a steady stream of APIC errors which are written to the syslog at varying rates (more frequently for me than for awen, it seems). Do you happen to see the APIC errors in your syslog, too? Since the kernel instructions indicate that both amd64_agp and a chipset specific module are needed for amd64 systems, maybe it's not too surprising that there is some kind of adverse effect to not using sis_agp at all. (I'm referring to the instruction that are visible from the curses menuconfig interface, I'm actually not sure where they are located to make a link to show what I'm talking about). -- sis 760 AGP broken on amd64 https://bugs.launchpad.net/bugs/34144 You received this bug notification because you are a member of Ubuntu Bugs, which is a direct subscriber. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

@Tormod Well, I'm not able to remove the sis_agp module once it's been loaded during the LiveCD boot, even after stopping gdm and manually removing all other modules related to video (radeon, drm, amd64_agp) - agpgart cannot be removed either, but that makes sense because it depends on sis_agp. I also tried booting in safe graphics mode. But it seems that once the sis_agp module is active, it can't be unloaded.

sybille, thanks, installing would be a good way to find out. Otherwise you can try to boot the live cd in single user mode by pressing F6 in the cd boot menu and adding single to the kernel parameters. Then rm the module and exit the shell to let it continue booting. Or, by adding break=bottom you'll get a initrd shell where you can delete stuff under /root (will be / in the booted system). I am not sure at which point the module is loaded, but you'll find out. If the initrd shell does not have lsmod you can use cat /proc/modules. -- sis 760 AGP broken on amd64 https://bugs.launchpad.net/bugs/34144 You received this bug notification because you are a member of Ubuntu Bugs, which is a direct subscriber. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

@sybille Didn't notice the side effect until you mentioned it. But i'm seeing the same errors in the syslog (though only once every 3-5 minutes on average). -- sis 760 AGP broken on amd64 https://bugs.launchpad.net/bugs/34144 You received this bug notification because you are a member of Ubuntu Bugs, which is a direct subscriber. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 34144] Re: sis 760 AGP broken on amd64
Hi, I'm still seeing this problem with the i386 version of Ubuntu 7.10, using the LiveCD. So, my experience is that the bug is not amd64 only. The AGP aperture size is set to 128M in my BIOS. But agpgart only recognizes it to be 4M: [EMAIL PROTECTED]:~$ sudo cat /var/log/dmesg | grep agpgart [ 132.042214] Linux agpgart interface v0.102 (c) Dave Jones [ 132.345993] agpgart: Detected SiS chipset - id:1888 [ 132.346322] agpgart: AGP aperture is 4M @ 0xf000 In the xorg log, dri seems to be loading fine but then there is the following error message: [EMAIL PROTECTED]:~$ sudo cat /var/log/Xorg.0.log | grep bind (EE) RADEON(0): [agp] Could not bind I have attached a complete copy of the xorg log. The following error appears in the kernel log: [EMAIL PROTECTED]:~$ sudo cat /var/log/kern.log | grep drm Oct 23 12:57:06 ubuntu kernel: [ 171.618188] [drm] Initialized drm 1.1.0 20060810 Oct 23 12:57:06 ubuntu kernel: [ 171.663073] [drm] Initialized radeon 1.27.0 20060524 on minor 0 Oct 23 12:57:12 ubuntu kernel: [ 173.904447] [drm:radeon_cp_init] *ERROR* radeon_cp_init called without lock held Oct 23 12:57:12 ubuntu kernel: [ 173.904654] [drm:drm_unlock] *ERROR* Process 8267 using kernel context 0 I have not tried the fix in https://bugs.launchpad.net/bugs/45942 in Ubuntu because I am trying the liveCD. However, I have tried renaming the sis_agp module in a Gentoo installation, with kernels up to 2.6.23, and this did not change how the AGP aperture size was identified as 4M. I've also tried patching the device ids in the kernel so that the particular model of the SIS chipset isn't identified, but that didn't fix things either although I might have made errors with this. Please let me know if other log files from a LiveCD boot would be useful. If anyone is willing to try to fix the issue and needs a tester, I will be happy to install Ubuntu as well. ** Attachment added: Xorg.0.log http://launchpadlibrarian.net/10131005/Xorg.0.log -- sis 760 AGP broken on amd64 https://bugs.launchpad.net/bugs/34144 You received this bug notification because you are a member of Ubuntu Bugs, which is a direct subscriber. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 34144] Re: sis 760 AGP broken on amd64
Ok, some people use amd64 and can fix the issue by renaming sis-agp.ko. Do they get the bind error before renaming? Or do we have (at least) two different bugs here? Sybille, you can try the workaround on a live cd by switching to a console (ctrl-alt-f1) and stopping X (sudo /etc/init.d/gdm stop) and unloading the module (sudo modprobe -r sis_agp) and delete it (locate sis_agp.ko, sudo rm ..., sudo depmod -a) and restart X (sudo /etc/init.d/gdm start). Since you also have a amd64 board (according to the original report) I guess the bug is amd64-hardware only. -- sis 760 AGP broken on amd64 https://bugs.launchpad.net/bugs/34144 You received this bug notification because you are a member of Ubuntu Bugs, which is a direct subscriber. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

@Tormod I'm using an AMD Sempron 2800+ and fixed it by renaming sis-agp.ko . And yes, the bind error was there before renaming. -- sis 760 AGP broken on amd64 https://bugs.launchpad.net/bugs/34144 You received this bug notification because you are a member of Ubuntu Bugs, which is a direct subscriber. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
