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."

[opensuse-amd64] SuSE 10.2 where is XF86Conf
by Harald Finster 30 Dec '06

30 Dec '06

Hello, after long frustrating days attempting to install Debian on my new system, I gave up and returned back to SuSE 10.2. Installation from DVD worked like a charm. (Except a small problem with an existing RAID, which could be solved by cleaning the discs with sand-paper :-) (seriously: dd if=/dev/null of=/dev/sdxxx) Now my current problem: I would like to use a Matrox G550 in dual head mode. At the moment, I am able to configure a single monitor with yast2/sax2 - no problem. According to an older posting, I would like to add an additional Display section in XF86Config. Now, the problem is: where is XF86Config? (I had a look at /etc/X11 and also tried a 'find') At the moment, the behaviour is quite strange: A Samsung Syncmaster 204B is attached to Port A A CRT ADI monitor is attached to Port B The 'console' (F1) is shown on both screens. After startup of runlevel 5, the X11 display appears on the ADI monitor (flickering), whereas the Samsung remains dark. If I swap the connectors, the situation remains the same. Any ideas/suggestions? Thanks in advance. Greetings Harald -- Dr.-Ing.

[opensuse-amd64] Is mapped_base still supported ?
by Nag Raj 27 Dec '06

27 Dec '06

Hi , Can anyone help me to find the following ? Happened to see /proc/<pid>/mapped_base entry in SLES9/10 AMD64 kernels. And it has the default value 1431654400 ( 0x55555000 ). $ cat /proc/29270/mapped_base 1431654400 This entry was introduced in SLES and RH in the past to alter the TASK_UNMAPPED_BASE entry dynamically ( to shift the mmap starting address ). And was effective in 32 bit kernels a lot to get more range for mmaps ( or to create large shared memory area). Not sure, why this entry is still present in SLES kernels and altering this entry doesn't help also ( ie mmap always starts at 0x2a95556000 = TASK_SIZE/3 . Can be verified with a small program and maps entry for the program). Is it a bug ? 1) Either it needs to be removed 2) or needs to be implemented so that users can alter this value ? Thanks in advance , Nagraj. __________________________________________________ Do You Yahoo!? Tired of spam? Yahoo!

[opensuse-amd64] How to build a cluster with 64 bit Opterons and SUSE?
by HG 23 Dec '06

23 Dec '06

Hi! We would like to build a cluster of multiple Opteron based computers. The usage is for scientific computing (multiple scientists running large processes usually at the same time... :-) Mainly computing but also some large flat file access, no DB stuff. Can this be done? (I think it can: http://www.theinquirer.net/default.aspx?article=36371 BMW seems to have done it except with woodcrests and not Opterons). How? Can't find anything really about getting any SUSE version or 2.6 kernel for that matter to work in cluster. Anybody have any experience? Any pointers to resources? Opensourse? Commercial? Whatever? -- HG. --------------------------------------------------------------------- To unsubscribe, e-mail: opensuse-amd64+unsubscribe(a)opensuse.org For additional commands, e-mail: opensuse-amd64+help(a)opensuse.org

[opensuse-amd64] VNC on OpenSuse 10.2
by Ben Ladd 21 Dec '06

21 Dec '06

Afternoon all, Open Suse 10.2 is now installed. I have a question about VNC sessions onto the Suse Box using RealVNC viewer. I cannot connect to the same session after disconnecting it like using Windows RealVNC server. This question has popped up a lot in my google searches and there are no answers for these guys! Is it because it is not possible? I use VNC for all my other boxes on my network and this is my first linux machine so it would be good if I could use the same stuff for RAS. How do you set the VNC server in linux to accept reconnection to old sessions? I have tried IPAddress:SessionNo ie: 192.168.0.x:1 and that always starts a new session where you have to log in. Same with ComputerName:SessionNo or just the computername or IPAddress. I'm guessing there are settings to change - but alas, my skills are poo. :) Thanks for any help.

[opensuse-amd64] Mute speakers when connecting headphones
by Jonas Israelsson 19 Dec '06

19 Dec '06

Hello Everyone. Have SuSE 10.2 installed on my Laptop (Acer Ferrari 5000) using KDE. The 'only' problem problem found so far (apart from waiting for the ATI-driver to be released) is that when connecting headphones the internal speakers does not mute. This is a "combined" headphone/SPDIF socket where I believe the muting is SW-controlled. I found some information saying that Kmix should have an option called. <Quote> Switches tab: mute 'Headphone Jack Sense' and 'Line Jack Sense' </Quote> However I do not have any 'Switches tab' at all and wonder if this a side effect of ALSA not being able to fully handle my Sound Card. Each time i boot the machine I see several errors (perhap 50-100 rows) like this : ALSA sound/pci/hda/hda_codec.c:212: hda_codec: invalid dep_range_val 0:7fff ALSA sound/pci/hda/hda_codec.c:212: hda_codec: invalid dep_range_val 0:7fff ALSA sound/pci/hda/hda_intel.c:590: hda-intel: get_response timeout: IRS=0x10 ALSA sound/pci/hda/hda_codec.c:212: hda_codec: invalid dep_range_val 0:7fff ALSA sound/pci/hda/hda_codec.c:212: hda_codec: invalid dep_range_val 0:7fff ALSA sound/pci/hda/hda_intel.c:590: hda-intel: get_response timeout: IRS=0x10 ALSA sound/pci/hda/hda_codec.c:212: hda_codec: invalid dep_range_val 0:7fff ALSA sound/pci/hda/hda_codec.c:212: hda_codec: invalid dep_range_val 0:7fff ALSA sound/pci/hda/hda_intel.c:590: hda-intel: get_response timeout: IRS=0x10 Sound Card: 00:14.2 Audio device: ATI Technologies Inc SB450 HDA Audio (rev 01) Just want a second opinion before filing a bug report.

That would be > a different matter harder to solve. Thanks... I think :-) Sorry, I do have to go and look for MPICH and LSF... as I do not know what those are. OpenMosix... I think I know. Little bit more about the needs: - multiple users (around 12+users) - all running scientific mathematical calculations on software ranging from matlab to self programmed software running with java, python, R, you name it - programs take from few minutes to days to run, usually at least couple of hours - users have hard time to find a "free" CPU/memory So, if we had the calculation servers set up as a cluster, users could find computing resources easily. Or more to the point, they would not have to do that, they just login to the (cluster) server and let the server worry about where it's running their processes. So, I do not know if your terms apply here or not. Altough, I think MPICH sounds like specialized software which we do not have (in that sense at least). -- HG. --------------------------------------------------------------------- To unsubscribe, e-mail: opensuse-amd64+unsubscribe(a)opensuse.org For additional commands, e-mail: opensuse-amd64+help(a)opensuse.org

[opensuse-amd64] KDE panel (kicker) crash
by John E. Perry 17 Dec '06

17 Dec '06

I just installed opensuse 10.2 on my Asus K8V-X SE with AMD Athlon 1800 running at 1533 MHz, 768MB, 120G hard drive. I have my drive partitioned with 2G swap, 2G /var, 20G /, and 87G /home. Usually I only burn CD1, abort the installation, and finish installation with the DVD iso in my home directory. This time, CD1 corrupted my grub, so I had to use another computer to burn the other two CD's and reinstall. Things seemed to go well until I logged onto the system after installation, whereupon the crash dialog box came up saying the front panel (kicker) had crashed with a signal 8, and I should notify the appropriate people of a possible bug in the application. All the KDE window manager stuff seems to have disappearted, but X runs fine, and I had a kterm running already, from which I can start, for instance, Konqueror, Firebird, and Thunderbird (which I'm using for this email). I have no application menu, and only the initial basic icons on the single desktop that seems to have survived the crash. I saved the detailed message tab text, and it's attached, in case it can help. How can I get KDE back up again? -- John Perry --------------------------------------------------------------------- To unsubscribe, e-mail: opensuse-amd64+unsubscribe(a)opensuse.org For additional commands, e-mail: opensuse-amd64+help(a)opensuse.org

[opensuse-amd64] Upgrading from 10.0 to 10.2 a Nightmare
by Constantine 'Gus' Fantanas 17 Dec '06

17 Dec '06

Today I received my 10.2 x64 DVD from Cheapbytes. When I tried to upgrade from my 10.0 to 10.2, the dependency checker seemed to hang. Namely, after the dependency window popped, I tried to resolve all dependencies manually. Eventually, I believe I did. Then, after hitting "Accept" to proceed with the upgrade, an ***EMPTY*** dependencies window popped up. Since it showed no dependencies or conflicts, I hit "Cancel" and then "Accept" in the YAST window to proceed. The dependencies window popped up again, empty. From there on, I got stuck in this loop. My original 10.0 x64 was the retail version. Since installing it, I updated several packages via apt-get and smart. (Some of them appeared locked in the YAST window; in one of my iterations, I manually unlocked them, but that did not help as I was caught in the same loop as described above.) The DVD I just got is Opensuse. Could that create a problem? Will I have to install 10.0 from scratch? Should I upgrade to 10.1 first and then 10.2?
