Hi,
(Sorry if this is off-topic but I really don't know where to turn to...)
Anyone with experience/knowledge about MTRR/PAT and who can tell me
where to find information about these things so that I might see if
there's a problem or not? I've tried google but in this case they're not
my friend... :-(
The MTRR of one of my machines look like this:
reg00: base=0x00000000 ( 0MB), size=2048MB: write-back, count=1
reg01: base=0x80000000 (2048MB), size=1024MB: write-back, count=1
reg02: base=0xbff00000 (3071MB), size= 1MB: uncachable, count=1
reg03: base=0x100000000 (4096MB), size=1024MB: write-back, count=1
The gfx card is a (pcie) Radeon HD3850 and the base address for the
framebuffer is 0xd0000000 (64-bit, prefetchable) [size=256M]. It also
has (what I believe is) registers at 0xf1000000 (64-bit,
non-prefetchable) [size=64K].
One of my other machines get's warnings about
All the relevant info that comes up when I use google relates to AGP but
I use PCIE, so is it still relevant? Also, are there other devices
besides the graphics card that would benefit from having a correct MTRR
setting?
TIA,
Peter K
