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 |
6 |
where to find information about these things so that I might see if |
7 |
there's a problem or not? I've tried google but in this case they're not |
8 |
my friend... :-( |

The MTRR of one of my machines look like this: |
11 |
reg00: base=0x00000000 ( 0MB), size=2048MB: write-back, count=1 |
12 |
reg01: base=0x80000000 (2048MB), size=1024MB: write-back, count=1 |
13 |
reg02: base=0xbff00000 (3071MB), size= 1MB: uncachable, count=1 |
14 |
reg03: base=0x100000000 (4096MB), size=1024MB: write-back, count=1 |
15 |
|
16 |
The gfx card is a (pcie) Radeon HD3850 and the base address for the |
17 |
framebuffer is 0xd0000000 (64-bit, prefetchable) [size=256M]. It also |
18 |
has (what I believe is) registers at 0xf1000000 (64-bit, |
19 |
non-prefetchable) [size=64K]. |

|
21 |
One of my other machines get's warnings about |
22 |
|
23 |
All the relevant info that comes up when I use google relates to AGP but |
24 |
I use PCIE, so is it still relevant? Also, are there other devices |
25 |
besides the graphics card that would benefit from having a correct MTRR |
26 |
setting? |
27 |

TIA, |
