After booting with enable_mtrr_cleanup, my MTRRs look like this:
reg00: base=0x000000000 ( 0MB), size= 2048MB, count=1: write-back
reg01: base=0x080000000 ( 2048MB), size= 1024MB, count=1: write-back
reg02: base=0x0bf700000 ( 3063MB), size= 1MB, count=1: uncachable
reg03: base=0x0bf800000 ( 3064MB), size= 8MB, count=1: uncachable
reg04: base=0x100000000 ( 4096MB), size= 1024MB, count=1: write-back
reg05: base=0x13c000000 ( 5056MB), size= 64MB, count=1: uncachable
reg06: base=0x0e0000000 ( 3584MB), size= 256MB, count=1: write-combining
And now desktop effects work. Thanks!
Cheers,
Marcus
