Setting up my MTRR correctly

**Gralamin** · 02-02-2010, 11:12 PM

I know you guys probably get this a lot. First of all, I have already taken a look at the various guides over the forums and internet, but have yet to find one that works.

My problem definitely matches the profile: Taking out 2 GB of system memory makes it work, but otherwise nothing does. Running Ubuntu 9.10 x64 with fglrx.

Important System Specifications:
Toshiba Satellite A350 PSAL6C-01N015
4 GB of Memory
ATI Radeon Mobility HD 3560

Still looking for help. Bump.

You'll want to enable MTRR cleanup in your kernel.

Visit http://www.kernel.org/doc/Documentat...parameters.txt and search for enable_mtrr_cleanup. That option should be appended to your boot parameters.

Also, change to the Lucid Lynx 2.6.32 kernel, there should be a patch in there that improves MTRR cleanup support.

from http://lkml.org/lkml/2008/9/28/7

Here is my current understanding of the MTRR problems. Please correct
any mistakes.

There are two broad reasons (use cases) for Linux to change MTRRs

(1) to clean up after bad BIOSes.

(1a) Some BIOSes don't make all the MTRRs the same on all processors.
This is just wrong and the kernel fixes this.

(1b) Some BIOSes, for some memory configurations, fail to specify that
certain bits of RAM should be cached. The current fix is to not use
that RAM, so the MTRRs are not actually changed, but they could be.

(2) to allow userland programs to adjust the caching regime for chunks
of memory.

Anything more complicated than that is over my head at the moment.

Already enabled, not helping.

Good idea. I'm planning on reformatng to ext4 anyway for when it comes out, so whats the harm in doing so a bit early?

Thanks for the help, I'll give it a shot.

Unfortunately a retarded edit time of 1 minute has been enforced on phoronix.com's forums - so I shall break forum courtesy and double post.

Here's some more interesting output you may find interesting of dmesg with the mtrr cleanup bits:

Code:

MTRR default type: uncachable
MTRR fixed ranges enabled:
  00000-9FFFF write-back
  A0000-BFFFF uncachable
  C0000-CFFFF write-protect
  D0000-EFFFF uncachable
  F0000-FFFFF write-protect
MTRR variable ranges enabled:
  0 base 000000000 mask F80000000 write-back
  1 base 080000000 mask FC0000000 write-back
  2 base 0C0000000 mask FE0000000 write-back
  3 base 100000000 mask F00000000 write-back
  4 base 0DFF00000 mask FFFF00000 uncachable
  5 disabled
  6 disabled
  7 disabled
x86 PAT enabled: cpu 0, old 0x7040600070406, new 0x7010600070106

reg 2, base: 3GB, range: 512MB, type WB
reg 3, base: 4GB, range: 4GB, type WB
reg 4, base: 3583MB, range: 1MB, type UC
total RAM covered: 7679M
Found optimal setting for mtrr clean up
 gran_size: 64K         chunk_size: 1G  num_reg: 4      lose cover RAM: 0G
New variable MTRRs
reg 0, base: 0GB, range: 4GB, type WB

reg 2, base: 3584MB, range: 512MB, type UC
reg 3, base: 4GB, range: 4GB, type WB

And some more interesting output:

Code:

$ cat /proc/mtrr
reg00: base=0x000000000 (    0MB), size= 4096MB, count=1: write-back
reg01: base=0x0dff00000 ( 3583MB), size=    1MB, count=1: uncachable
reg02: base=0x0e0000000 ( 3584MB), size=  512MB, count=1: uncachable
reg03: base=0x100000000 ( 4096MB), size= 4096MB, count=1: write-back

at OP: what is your problem exactly? Your mtrr are looking fine.
Also, look at dmesg, the part about TOM and TOM2 is the important stuff.

Probably you don't have a problem with mtrr.
