IOMMU...PCI memory hole...MTRR...I give up.

by David W. Hankins

I have an MSI K8D-Master-F motherboard with two Opteron 244's. It recently got retasked as a desktop machine due to another system's failure...I thought the little ATI Rage built into the motherboard would make more than a sufficient 2d desktop type framebuffer, and as far as other stuff inside this box... this should be a pretty kick ass, high performance workstation. But I can literally watch the screen redraw if I switch virtual desktops. Painfully slow. Thinking this was just some crippled built-in video bug, I threw in an old nVidia card we had lying around in one of the regular PCI slots. Slightly slower, if you can believe it. I think this: mtrr: type mismatch for e5000000,1000000 old: uncachable new: write-combining And of course this: $ cat /proc/mtrr reg00: base=0xc0000000 (3072MB), size=1024MB: uncachable, count=1 reg01: base=0x00000000 ( 0MB), size=4096MB: write-back, count=1 Has something to do with it (and may also explain why I'm getting less than stellar performance out of other PCI devices, such as the RAID array that has a 128MB memory region the driver directly reads and writes on). The above is with the nVidia PCI card inserted, the built-in ATI card would also emit a similar mtrr rejection message, just the address is different, and the system would only list 512MB uncachable without the nVidia. Also notice that there's 4GB installed in this machine, in 2 2GB DIMMs installed in one bank together. And yet the BIOS map: BIOS-provided physical RAM map: BIOS-e820: 0000000000000000 - 000000000009fc00 (usable) BIOS-e820: 000000000009fc00 - 00000000000a0000 (reserved) BIOS-e820: 00000000000e0000 - 0000000000100000 (reserved) BIOS-e820: 0000000000100000 - 00000000bfff0000 (usable) BIOS-e820: 00000000bfff0000 - 00000000bffff000 (ACPI data) BIOS-e820: 00000000bffff000 - 00000000c0000000 (ACPI NVS) BIOS-e820: 00000000ff7c0000 - 0000000100000000 (reserved) Lists nothing beyond the 4GB mark where that memory might reasonably have been moved to. Assuming this is just a neglectful BIOS, I tried setting 'mem=4G' and 'memmap=1G@4G' kernel options, to define the 1GB 'hole' I presume is being placed here, and which got me this added line to dmesg: user: 0000000100000000 - 0000000140000000 (usable) But still only 3GB available. To add even more insult to rising injury, I noticed while looking through dmesg that the IOMMU is being disabled. It appears the value being advertised by the CPU's: CPU 0: aperture @ 1b80000000 size 128 MB Is being rejected because it lies (WELL) above the 4GB mark. I've been going through archives and I'm not finding anything that looks like actionable advice. The latest BIOS MSI's webpage lists for this motherboard is 1.1: already installed. It has no option for 'pci hole: software'. The only options I'm finding are memory bank interleaving (which I tried disabling), and 'Disabled/Best-Fit/Absolute' settings for the IOMMU, as well as its aperture size (128M, which I might increase if it would be used rather than ignored...). One post in the archive that matched on motherboard make and model looks confused to me, because he refers to his BIOS as AWARD 2.0, but the only BIOS MSI puts out for this board is AMI (versioned 1.1). In summary what I'd like to know is: 1) Where is the 'go fast' button? re: pci video that's slower than even isa video should be (and presumably similar performance problems on other PCI devices). 2) How do I get the last 25% of my memory back? 3) How do I get the system to put the IOMMU somewhere in the range it stole under 4G (so Linux can use it)? Can Linux move this on its own accord? Thanks in advance for any and all help. -- David W. Hankins "If you don't do it right the first time, Software Engineer you'll just have to do it again."

Hello, You should use different network addresses for your wifi link. You have two different interfaces connected to the same network 192.168.1.x, your operating system doesn't know where to send packets to. Try: PC1 - eth0 - 192.168.1.2/24 --> modem ( 192.168.1.1 ) -> Internet - ra0 - 10.0.0.1/24 routes on PC1: network 192.168.1.0/24 dev eth0 network 192.168.2.0/24 via 10.0.0.2 network 0/0 via 192.168.1.1 PC2 - ra0 - 10.0.0.2/24 - eth0 - 192.168.2.1/24 routes on PC2 network 192.168.2.0/24 dev eth0 network 0/0 via 10.0.0.1 First of all, configure both ra0 interfaces and get ping working from both computers to 10.0.0.x interfaces. Later configure connection to the internet from PC1, and finally: Configure PC1 to masquerade 192.168.2.x traffic. hope this helps, > On PC n°1, there is an ADSL modem, plugged on eth0 and whose IP address is > 192.168.1.1.

[opensuse-amd64] YOU problem

by Philippe Andersson

Hi list, Maybe not the best place for this question, but I'm sure some of you must have the answer: Fresh install of OpenSuSE 10.2 (minimal install -- no X). Network properly configured. Start "yast" in ncurses mode, select "Online Update". It loads the list of installed packages and then reports that no patches are available. Based on a quick look on the site (ftp.suse.com), it looks like some patches are available (which is expected, a few months after the release). Is there some change in Yast that I missed (since the 9.3 version) ? YOU used to ask you which server it should connect to to retrieve the patches, but it doesn't seem to do that any longer. Any help or pointer to the relevant doc is appreciated. Thanks in advance. Cheers. Bye. Ph.

[opensuse-amd64] Trouble installing openSuSE 10.2 due to pci_init

by brian_linux

Hello: I am having difficulty upgrading my openSuSE 10.1 installation to openSuSE 10.2. In fact, my difficult arises from the fact that I cannot reliably boot into the installation program. Background: (1) I have a Tyan K8HM 3892S motherboard and two dual-core Opterons. (2) I installed the latest BIOS (1.05). I tried a number of BIOS settings but they are currently set to "optimal defaults". (3) openSuSE 10.1 runs without any known problems. Originally I had the double realtime clock issue but a previous BIOS update fixed that. (4) I'm using the openSuSE 10.2 install DVD. I checked the MD5 and it matched. I have also burned a number of DVDs, even using different programs and the behavior is consistent. Issue: (1) The DVD starts to boot. In fact I can get to the "main screen" where I can select to "Boot from the Hard Drive", "Install", ... (2) When I select install to start the upgrade, usually the system hangs. (3) I installed using text mode and the initcall_debug kernel option and I can see progress up until the following: Calling initcall 0xffffffff80317987: pci_init +0x0/0x2b() What I find weird is that sometimes the system will get into the install program, but the vast majority of the time it will not. So it's intermittent. I haven't been able to identify any pattern that I can use to predict whether it'll work on any given boot sequence. Does anyone have any suggestions? This isn't a crisis since I have 10.1 working well, it's just that I really wanted to upgrade to 10.2. Of course I'm willing to provide additional information to the best of my ability. I'm somewhat competent, but must admit that I'm a little out of my comfort zone. Any help or suggestions would be greatly appreciated. Thank you.

[opensuse-amd64] opensuse 10.2 a100u2w and k8temp modules AWOL on x86_64?

by Bernd Felsche

I've recently installed opensuse 10.2 (release) on some new hardware and have found that the a100u2w and k8temp modules are missing. CPU AMD Athlon(tm) 64 X2 Dual Core Processor 4200+ in Gigabyte GA-M55plus-S3G mainboard with 1GB RAM Everything else works fine. Nice and stable. The former drives the Initio A100U2W SCSI host adapter (modprobe during boot tries but can't load absent module) and the latter is suggested by sensors-detect to ascertain the processor temperature. Driver `k8temp' (should be inserted): Detects correctly: * ISA bus, undetermined address (Busdriver `i2c-isa') Chip `AMD K8 thermal sensors' (confidence: 9) I've tried to figure out why they are absent but can't work it out. Kernel configuration provides the option to build the a100u2w module, and it's compiling now, but I'm stuck on the k8temp as there's no obvious option to build that. -- /"\ Bernd Felsche - Innovative Reckoning, Perth, Western Australia \ / ASCII ribbon campaign | "If we let things terrify us, X against HTML mail | life will not be worth living." / \ and postings | Lucius Annaeus Seneca, c. 4BC - 65AD. --------------------------------------------------------------------- To unsubscribe, e-mail: opensuse-amd64+unsubscribe(a)opensuse.org For additional commands, e-mail: opensuse-amd64+help(a)opensuse.org
