[Bug 224404] Re: MTRR is not properly setup on Intel Northbridge Chipset (P35, X38, X48) with more than 3GB RAM and with Memory Remapping Enabled
ilna: I notice that error now on my Fedora 11. I'm too lazy to check, but it looks as if the kernel header changed and hijacked a symbol that I had been using. quick fix: issue this shell command in the mtrr directory sed -i -e 's/\mtrr_type\/_dhr/g' mtrr-uncover.c Then make again. I am a bit surprised that you have MTRR problems when you are using a new kernel. I would have thought that the kernel's code to clean up MTRRs would be working. This code was added to the official kernel last year. I would like to know more. If you do report it as a new bug (and I don't know if you should report a new bug or add to this report), please do add a comment here telling us where to find the new report. -- MTRR is not properly setup on Intel Northbridge Chipset (P35, X38, X48) with more than 3GB RAM and with Memory Remapping Enabled https://bugs.launchpad.net/bugs/224404 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

I believe to get access to all 4GB of memory in 32 bit version requires the use of PAE or a BIGMEM kernel. To get access to all the memory in 32 bit version you would have to enable memory-remapping.

I've written the program. It works on my one system. Who knows if it works anywhere else. Fetch it from ftp://ftp.cs.utoronto.ca/pub/hugh/mtrr-uncover- 2008sept18.tgz Untar it. cd into the new directory. Type make. Read the manpage man ./ mtrr-uncover.8 Run the command (just a test!) ./mtrr-uncover. You should be able to see how the MTRRs are set up more clearly that /proc/mtrr shows it. You will also see the proposed revised version and the lines to be written to /proc/mtrr to effect that change.

Just thought I would add my $0.02 because I have a Foxconn X38A board with a C2Q 6600 and 4GB of RAM. I also have a Sapphire ATI 3870 card. When I did a fresh install of Ubuntu 8.04, everything came up fine (and very fast), then I enabled the fglrx driver and when the system came back up, it went to a blank screen and nothing had any effect. I tried rebooting using the Reset button a couple of times and there was one situation where the computer did a spontaneous reboot after the splash screen, but mostly it would just sit there blank. And it was a powered blank, i.e. it was clear that the LCD backlight was on and the power light was green (no powersave). After reading this article, I went into the BIOS and disabled the memory mapper and when I rebooted, the system came right up. If there are any commands I can issue to collect data to help with this bug, please let me know and I can turn my memory mapper back on, make it crash and provide information, if it would help this whole situation somehow. -- MTRR is not properly setup on Intel Northbridge Chipset (P35, X38, X48) with more than 3GB RAM and with Memory Remapping Enabled https://bugs.launchpad.net/bugs/224404 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

The only issue is that the hard lock actually has something to do with a closed source package (i.e. fglrx has an issue with the mtrr table, but the mtrr table is actually handled by the BIOS and kernel - then this problem lies with our ability to get information out of the fglrx binary driver). Further, since the binary drivers don't have debug symbols in them, we don't get a core dump out (it would be nice if I could send this information on to AMD/ATI to allow them a chance to fix the driver - provided its a bug in their code). -- MTRR is not properly setup on Intel Northbridge Chipset (P35, X38, X48) with more than 3GB RAM and with Memory Remapping Enabled https://bugs.launchpad.net/bugs/224404 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Similar situation: When I use fglrx with default configuration it blanks the screen and hard locks the system (VTs and network die). I have to disable AIGLX, Composite, Accleration and DRI for it to work at all. If I change VTs it crashes. I don't have a BIOS option for Memory Re-Mapping so I can't test turning it on/off.

That could be a fix. However it appears to be in regards to x86 (IA32) - although, this fix might work for 64 bit architectures.

Thank you, sir. Yes I should've mentioned that I have the same exact configuration as you down to the same video card. I've been trying out various mtrr modifications for a couple of days now to no avail. Thought instead that I'd just see if anyone had the same exact config/setup as me instead of me trying to figure this out the hard way. Btw I tried out your table changes and it worked perfectly. I had looked at that rage3d.com page before and tried it out. Obviously it needed modifications for it to apply to my system but I guess I was missing something because I wasn't doing it correctly. I'll go back now and see what logic I was missing. e -- MTRR is not properly setup on Intel Northbridge Chipset (P35, X38, X48) with more than 3GB RAM and with Memory Remapping Enabled https://bugs.launchpad.net/bugs/224404 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

[Bug 224404] Re: MTRR is not properly setup on Intel Northbridge Chipset (P35, X38, X48) with more than 3GB RAM and with Memory Remapping Enabled
I think the issue that we are seeing, is related to the kernel thinking that the graphics card memory is uncachable. If the mtrr tables are changed such that the memory at d000 is set to write-back rather than uncachable So: reg00: base=0xd000 (3328MB), size= 256MB: uncachable, count=1 is changed to reg00: base=0xd000 (3328MB), size= 256MB: write-back, count=1 This guess is due to the line starred below (***) ... found by sudo lspci -vv and what appears to be the congruent line in the mtrr tables. 01:00.0 VGA compatible controller: ATI Technologies Inc Radeon HD 3870 (prog-if 00 [VGA controller]) Subsystem: Hightech Information System Ltd.

That's a very good question Greg :P On the other hand, reconfiguring mttr tables won't damage your hardware, but can slow down the computer like a 8086, or cause a total crash (without BSOD xD), requiring you to reset manually. I needed two crashes before finding a compatible mtrr table. It's very important to disable all the old registers before adding new ones, or you will crash again.
