[gentoo-user] MTRR setting? Where could I have put it?

[gentoo-user] MTRR setting? Where could I have put it?

[Willie Wong]

Hi list:

  I need some help with my memory.

  Recently when I quit the X server, the following can be seen in the
  sys log:

Jan 20 18:06:34 e-nibbles mtrr: no MTRR for e8000000,2000000 found

  and on the TTY where I issued X init, a similar message is shown,
  but the message is not echoed in /var/log/Xorg.0.log

  Now, I remember having entered something like that somewhere way
  back, when I was using the ATI drivers for my laptop (instead of the
  radeon drivers from Xorg). The problem is, I cannot remember where
  such a line would possibly go! Does anyone have any ideas where I
  can start searching?

Thanks in advance, 

W

don't do it. Just don't do that. It should not be necessary. Instead look at 
the mtrr cleanup options in make menuconfig.

Yes, my point exactly! That *should not* be necessary any longer, so I
am trying to figure out where I might have put this thing which I
remembered having manual inserted so I can undo the damage. 

Also, what is this MTRR cleanup option? I can't seem to find it?

are you using a recent kernel? 2.6.27 or 28?

I am using both.  I have a mtrr entry in my kernel boot line like this: mtrr:4

but when configuring the new kernel I came across this option:

MTRR cleanup enable value (0-1)

which confused me.  What am I supposed to choose here, other than the
default 0 value?

choose 1 with the 28 kernel and everything is fine. That was my success:

reg00: base=0xfffe0000 (4095MB), size= 128KB: write-protect, count=1
reg01: base=0xfffc0000 (4095MB), size= 128KB: uncachable, count=1
reg02: base=0x00000000 (   0MB), size= 512MB: write-back, count=1

reg07: base=0x00000000 (   0MB), size= 128KB: uncachable, count=1


changed to

reg00: base=0x000000000 (    0MB), size= 1024MB, count=1: write-back
reg01: base=0x03f500000 ( 1013MB), size=    1MB, count=1: uncachable

Sorry for the late reply, I was having some problems with my mail.

I am using 2.6.26 right now. I guess that is the problem. Let me try a
more recent one and report back.

Sorry, but this does not help. I have that after I terminate X, the
following line on the console:

error setting MTRR (base = 0xe8000000, size = 0x02000000, type = 1) Invalid argument (22)

and the following

Is there anything I misconfigured? 

Any other ideas?

I read something about booting with "mtrr_cleanup_debug debug" in the
command line. This will print you out what to set in mtrr_chunk_size in
the commandline. Didn't test it but check that.

It seems to be appeared on 2.6.28 kernel. But not 2.6.26 kernel.
I got both as on my box as the gspca driver for my web camera seems only
worked on the 2.6.26 kernel.

The error I run into is mostly only cosmetic. The error happens AFTER
I terminate X. So far there has been no loss of functionality. After a
thorough search of my harddrive, I am beginning to think that this is
not a problem with my configuration per se, but a bug with the Xorg
radeon driver. 

Note that for me this message occured for both 2.6.26.5 and 2.6.28.1
vanilla sources, and for both 6.9.0 and 6.10.0 Xorg radeon drivers.

Happened here on both .26 and .28 with the nv driver. But, like you said
the message only appeared after X terminated. I only experienced 1 X crash
during a week of nv driver usage. No, such messages with the nvidia 
proprietary drivers however. FWIW the following are the config opts i use 
for my current .28 gentoo-sources:

zsh % zgrep -i mtrr /proc/config.gz
CONFIG_MTRR=y
# CONFIG_MTRR_SANITIZER is not set

I pass mtrr:4 to the kernel command line.
