Binary package hint: xserver-xorg-video-intel
Today I upgraded my RAM from 1GB to 4GB. Everything worked fine but I noticed that scrolling in Firefox and dragging windows is noticeably slower than before. I checked this again by removing 2GB and got the same results.
I suspect it has to do with this line from the X server:
(WW) intel(0): Failed to set up write-combining range (0xd0000000,0x10000000)
If this is something the kernel is responsible for, please feel free to reassign accordingly.
I have no options in my BIOS to change anything that might be relevant to this (memory mapping, etc.)
This is a Samsung Q45 with Intel X3100 graphics.
I'll attach more debug info.

After upgrading my Laptop to 4GB RAM my MTRRs are set up in such a way that X can't set up a write-combining range for the video memory anymore, causing a noticable loss of performance
/proc/mtrr with 2GB:
reg00: base=0x00000000 ( 0MB), size=2048MB: write-back, count=1
reg01: base=0x7f700000 (2039MB), size= 1MB: uncachable, count=1
reg02: base=0x7f800000 (2040MB), size= 8MB: uncachable, count=1
reg03: base=0xd0000000 (3328MB), size= 256MB: write-combining, count=1
/proc/mtrr with 4GB:
reg00: base=0xc0000000 (3072MB), size=1024MB: uncachable, count=1
reg01: base=0x00000000 ( 0MB), size=4096MB: write-back, count=1
reg02: base=0x100000000 (4096MB), size=1024MB: write-back, count=1
reg03: base=0xbf700000 (3063MB), size= 1MB: uncachable, count=1
reg04: base=0xbf800000 (3064MB), size= 8MB: uncachable, count=1
The video memory is at 0xd0000000 (256MB). Note that this range is already included in reg00 and reg01, so the X server cannot set up a write-combining range.
If I manually fix the ranges to look like this:
reg00: base=0xc0000000 (3072MB), size= 256MB: uncachable, count=1
reg01: base=0x00000000 ( 0MB), size=2048MB: write-back, count=1
reg02: base=0x100000000 (4096MB), size=1024MB: write-back, count=1
reg03: base=0xbf700000 (3063MB), size= 1MB: uncachable, count=1
reg04: base=0xbf800000 (3064MB), size= 8MB: uncachable, count=1
reg05: base=0x80000000 (2048MB), size=1024MB: write-back, count=1
reg06: base=0xe0000000 (3584MB), size= 512MB: uncachable, count=1
, i.e. explicitly excluding 0xd0000000 (256MB) from both problematic ranges, then the X server can set up the write-combining range again:
reg00: base=0xc0000000 (3072MB), size= 256MB: uncachable, count=1
reg01: base=0x00000000 ( 0MB), size=2048MB: write-back, count=1
reg02: base=0x100000000 (4096MB), size=1024MB: write-back, count=1
reg03: base=0xbf700000 (3063MB), size= 1MB: uncachable, count=1
reg04: base=0xbf800000 (3064MB), size= 8MB: uncachable, count=1
reg05: base=0x80000000 (2048MB), size=1024MB: write-back, count=1
reg06: base=0xe0000000 (3584MB), size= 512MB: uncachable, count=1
reg07: base=0xd0000000 (3328MB), size= 256MB: write-combining, count=1
I'm not sure who is responsible for the MTRRs. Or in case of a broken BIOS, if the kernel can sanitize them anyway.
