Re: New ATI fglrx drivers work with AMD64

Manuel,

These MTRR errors are the reason why direct rendering does not work.

I've just faced a similar problem. Hopefully, in my Tyan Tiger K8W S2875 BIOS setup there is an option MTRR Mapping which can be either Continuous or Discrete. The former "explicitly describes the PCI hole as non-cacheable" while the latter "leaves the PCI hole below the 4G boundary undescribed". Continuous is default. All MTRR errors and fglrx direct rendering ability had been fixed when I switched MTRR Mapping to Discrete.

You can see the current MTRR state with 'cat /proc/mtrr'.
This is how my MTRR looked with Continuous mapping:

reg00: base=0x00000000 (   0MB), size=4096MB: write-back, count=1
reg01: base=0x100000000 (4096MB), size=1024MB: write-back, count=1
reg02: base=0xc0000000 (3072MB), size=1024MB: uncachable, count=1   <==== this was problematic

And how they look now:

reg00: base=0x100000000 (4096MB), size=1024MB: write-back, count=1
reg01: base=0x00000000 (   0MB), size=2048MB: write-back, count=1
reg02: base=0x80000000 (2048MB), size=1024MB: write-back, count=1
reg03: base=0xe0000000 (3584MB), size= 128MB: write-combining, count=1
reg04: base=0xf0000000 (3840MB), size= 128MB: write-combining, count=1

I guess that two 128Mb regions are video card memory and AGP aperture.
