IOMMU...PCI memory hole...MTRR...I give up.
by David W. Hankins 26 May '07

26 May '07

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."

missing ksym kernel install
by Rene Salmon 31 Aug '06

31 Aug '06

Hi, I downloaded and compiled a 2.6.16 vanilla kernel from kernel.org for my suse 10.1 box. When I do a "make rpm-pkg" in the kernel source directory I get this error message: Finding Provides: /usr/lib/rpm/find-provides kernel Finding Requires: /usr/lib/rpm/find-requires kernel Finding Supplements: /usr/lib/rpm/find-supplements kernel error: line 48: Dependency tokens must begin with alpha-numeric, '_' or '/': error: Failed to find Supplements: Provides: kernel-2.6.16.28 ksym(DAC1064_global_init) = 8d3987b ksym(DAC1064_glob al_restore) = 86bc4e3f ksym(DMAbuf_close_dma) = c88b42ab ksym(DMAbuf_inputintr) = eb315d99 ks but the make continues and is able to generate the x86_64 rpm. The problem is when I try to install the generated RPM I get a long list of ksym missing dependencies: error: Failed dependencies: ksym(schedule) = 1000e51 is needed by kernel-2.6.16.28-1.x86_64 ksym(xfrm_policy_walk) = 101aa673 is needed by kernel-2.6.16.28-1.x86_64 Any ideas as to why "find-supplements kernel" is failing? I am assuming this is why I don't have the "ksyms"? Thanks you for any help with this.

Complete rebootable backup/clone
by Pierre Patino 25 Aug '06

25 Aug '06

Hello everyone As I'm on hold with Novell, I might as well pose a question here. Is there any tool/program/script out there (free or not) that will copy selected directories from the bootable hard drive and generate a bootable DVD that would self-install? I heard that YaST was going to find that feature but I haven't found it yet (SLED-10). By the way, Norton GHOST will not work with reiserfs TIA & Cheers

yast crashes when installing new packages
by Ryan Biltz 21 Aug '06

21 Aug '06

Recently yast has been crashing on me when I install packages. Also I run in to hundreds of dependency conflicts when I do updates. How do I refresh my screwed up yast tool? Kind of general question but it's a problem that's really hard to google for. I have OpenSuSE 10.1 on amd64. Thanks. --ryan

SuSE AMD 64 bit supports Intel "Core 2 Duo" ?
by Jean-Lin Pacherie 20 Aug '06

20 Aug '06

Is it politycaly correct to ask here if the new "Core 2 Duo" processors will be suported by SuSE 64bit ? I planed to build a server with AMD 64 x2 processor and / or Opteron 275 but the announces of the "Core 2 Duo" chnaged my mind. In any cases, I will keep SuSE on this new workstation but I need the best processor power. Any clue ? Thank's Jean-Lin

Lost my /dev/loop0
by Constantine 'Gus' Fantanas 18 Aug '06

18 Aug '06

Hi all. I tried to mount an encrypted USB stick, which was created with YAST, but I got an error that /dev/loop0 did not exist (it did not, indeed). However, the necessary modules, such as dm-crypt, dm_mod, twofish, aes, and cryptoloop are loaded. Am I missing anything? I am running kernel 2.6.17 (SuSE kernel of the day, installed a month and a half or so ago). CF -- Running 64-bit Linux on AMD64

Upgrade from 10.0 to 10.1 question
by Janis Klava 17 Aug '06

17 Aug '06

Gentlemen, I recently upgraded my T30 ThinkPad from SuSE 10.0 to Opensuse 10.1 (32 bit) The problem is that I am now unable to do an online YOU upgrade. It goes through the motions of checking dependncies and then comes back with the message, "No patches available". As I would like to upgrade my Opteron box, has anyone had similar problems or is the solution simply to purchase 10.1, no YOU for Opensuse?? Janis

Need help with keychain setup
by Günter Dannoritzer 17 Aug '06

17 Aug '06

Hi, I have setup keychain the way it is explained in the man page. So I added: keychain id_rsa [[ -f $HOME/.keychain/$HOSTNAME-sh ]] && \ source $HOME/.keychain/$HOSTNAME-sh [[ -f $HOME/.keychain/$HOSTNAME-sh-gpg ]] && \ source $HOME/.keychain/$HOSTNAME-sh-gpg to my ~/.bash_profile file When I log into KDE I receive the asked password window correct and can enter the passphrase for id_rsa. But when I then try to login from a shell to the remote computer which key got added to ssh-agent, I am getting asked again for the passphrase. On another computer I have setup keychain by adding the above configuration lines to ~/.bashrc, but according to the man page that does not seem to be the correct way. At least there it works and I can login from each shell to the remote computer without having to enter the passphrase. Do I misunderstand the function that I should get by adding the above configuration to bash_profile? What is the correct way to set it up so that every shell will consult ssh-agent for the passphrase? Thanks for any help. Cheers, Guenter

Lost in hardware specs...
by Dylan 16 Aug '06

16 Aug '06

Hi all, I'm looking to build a machine for some fairly hefty audio, video and graphics processing. I'm having trouble getting through the information about x86-64 processors and motherboards and chipsets. Sound and graphics cards, hard drives and optical media I can deal with. Basically, I'd like to aim for a dual processor machine with plenty of memory. Unfortunately, I can't afford to lay out for the final spec in one go so I figure I'll start off with lower spec and upgrade as I need to/can afford to. To that end, I have some questions: Which processors can I use in an SMP setup? I know they need to be a "pair", but do all the x86-64 units play SMP, or only a few? Is it possible to upgrade from an Athlon to an Opteron on X2? Any reccomendations as to motherboards would be most welcome. Thanks Dylan -- "The man who strikes first admits that his ideas have given out." (Chinese Proverb) -- "The man who strikes first admits that his ideas have given out." (Chinese Proverb)
