Intel Video troubleshooting/performance improvement link

Re: Intel Video troubleshooting/performance improvement link

this is what i got;

~$ sudo cat /proc/mtrr

reg00: base=0x000000000 ( 0MB), size= 2048MB, count=1: write-back
reg01: base=0x080000000 ( 2048MB), size= 1024MB, count=1: write-back
reg02: base=0x0fff00000 ( 4095MB), size= 1MB, count=1: write-protect
reg03: base=0x0bc000000 ( 3008MB), size= 64MB, count=1: uncachable
reg04: base=0x0bbc00000 ( 3004MB), size= 4MB, count=1: uncachable

i dont notice anything....konqueror is still shows some garbled graphics..my kmenu button is still phased out. can only see the outline.


i did all the changes except use the new kernel.

i modified the xorg file,

Option "AccelMethod" "uxa"
Option "EXAOptimizeMigration" "true"
Option "MigrationHeuristic" "greedy"
Option "Tiling" "false"

executed fixmtrr.sh via systemsettings->auto-start, installed the new xorg drivers and still cant see the line that says 'write-combining'

Commenting out the 'Accelmethod' option helps - things are not so sluggish. still having problems with 'write-combining' not appearing in /proc/mtrr

Re: Intel Video troubleshooting/performance improvement link

Well, after getting back to my previous level of acceleration, I got greedy.

I decided to go the whole "Optimal" route and install the 0.30 kernel.

It made no difference in Tux Racer or in Stellarium, BUT, it made a SIGNIFICANT difference in Second Life. Without the 0.30 kernel SL would hover around 5 to 10 fps, with the occasional climb to around 25-30 fps when I was moving the avatar vigorously. WITH the 0.30 kernel SL hovers around 15 fps and during movement of the avatar the fps climbs to 30-40 !!

And, so far, I haven't found any "restricted" processes which are not working.

i envy u bro...imy fixmtrr.sh has a permission problem....

when i try to run fixmtrr.shh i get;

techie@compaq-laptop:/usr/local/bin$ ./fixmtrr.sh
Extracing base address and memory size from lspci -v
c0000000
10000000

Supplying corrected MTRR ranges to /proc/mtrr
./fixmtrr.sh: 43: cannot create /proc/mtrr: Permission denied
reg00: base=0x000000000 ( 0MB), size= 2048MB, count=1: write-back
reg01: base=0x080000000 ( 2048MB), size= 1024MB, count=1: write-back

reg04: base=0x0bbc00000 ( 3004MB), size= 4MB, count=1: uncachable

thats why i am not able to achieve 'write combining'

how r u running yr script? via system settings ->advanced -> autostart -> add script right?

i have made the script executable as shown below;

ls -al fixmtrr.sh

-rwxr-xr-x 1 techie techie 1012 2009-05-01 06:43 fixmtrr.sh

? ideas?

Re: Intel Video troubleshooting/performance improvement link

My script is installed thusly:

-rwxr-xr-x 1 root root 1012 2009-04-30 17:43 fixmtrr.sh

I run it manually (since I am running KDE4.2.4) thusly:

sudo /usr/local/bin/fixmtrr.sh

though it doesn't seem to make any difference if I used sudo or not.

After verifying that I had accelerated my 3D I added the script to the KDE4 autostart option in SystemSettings.

Commenting out the 'Accelmethod' option helps - things are not so sluggish. still having problems with 'write-combining' not appearing in /proc/mtrr

I thought the whole purpose of this series of changes was to ENAbLE UAX acceleration.

What kind of Intel video chip do you have?

yup! Pushing me all the way! And silly me, I kept thinking there was a cliff ahead...

Re: Intel Video troubleshooting/performance improvement link

I finally went to the bleeding edge configuration too. It was pain free, no problems, and took all of 10 minutes. I don't really play games but it sure made a difference with Hulu. I could never get smooth full-screen video with Hulu until I made the optimizations.

the same as yours.

i have since enabled uxa AND also enabled tiling. the issue i have now is with the fixmtrr.sh. not able to get write combining with that.

i dont know why there is permission denied problem when executing fixmtrr.sh.

my /proc/mtrr belongs to root.root

ls -al /proc/mtrr
-rw-r--r-- 1 root root 0 2009-07-15 13:46 /proc/mtrr

sudo chmod +x /proc/mttr

It needs to be executable (do another ls -l after that command, it will show an x)

You skipped the second step in this sequence:

$ sudo wget http://launchpadlibrarian.net/26193373/fixmtrr.sh -O /usr/local/bin/fixmtrr.sh
$ sudo chmod +x /usr/local/bin/fixmtrr.sh

Re: Intel Video troubleshooting/performance improvement link

Yes, I was pointing to the wrong location (the /proc entry, not the script). Thanks for the correction, GreyGeek!

No. i did make my fixmtrr.sh executable.

Should i do sudo chmod +x /proc/mttr ?


Currently;

ls -al /proc/mtrr

Re: Intel Video troubleshooting/performance improvement link

No, /proc/mtrr is not executable. You can leave it alone, it has the right permissions. The fixmtrr.sh script is pretty simple. It writes to the mtrr file with the following line:

echo "base=0x$address size=0x$hsize type=write-combining" >| /proc/mtrr && echo success

A permission denied would result if you can't write to /proc/mtrr.
