mtrr setup
I don't think my mtrr is setup correctly. I have an asus laptop with sis630
chipset.
I have setup the shared graphics memory in the bios to 32 mb.
dmesg reports:
Linux agpgart interface v0.99 (c) Jeff Hartmann
agpgart: Maximum main memory to use for agp memory: 232M
agpgart: Detected SiS 630 chipset
agpgart: AGP aperture is 64M @ 0xd0000000
[drm] AGP 0.99 on SiS @ 0xd0000000 64MB
[drm] Initialized sis 1.0.0 20010503 on minor 0
> cat /proc/mtrr
reg00: base=0x00000000 ( 0MB), size= 256MB: write-back, count=1
reg01: base=0x10000000 ( 256MB), size= 32MB: write-back, count=1
reg02: base=0xd8000000 (3456MB), size= 128MB: write-combining, count=4
reg03: base=0xd0000000 (3328MB), size= 64MB: write-combining, count=1
Does this look right?
I am trying to optimise my dvd playback. I get some demux buffer overruns. CPU
use is at 90-95%.
