when trying to append some commands, e.g.:

enable_mtrr_cleanup mtrr_spare_reg_nr=1 mtrr_gran_size=32M mtrr_chunk_size=128M

or

enable_mtrr_cleanup mtrr_spare_reg_nr=0

it doesn't make any change


this would yield the following result:

Jun  5 00:20:47 localhost kernel: [    0.000000] please specify
mtrr_gran_size/mtrr_chunk_size





Is this some kind of kernel BUG due to the negative value (- 0G) ?

MTRR seems to be a topic that is not widely discussed or thoroughly
understood when using google to find answers.

cat /proc/mtrr
reg00: base=0x000000000 (    0MB), size= 8192MB, count=1: write-back
reg01: base=0x200000000 ( 8192MB), size= 1024MB, count=1: write-back
reg02: base=0x0c0000000 ( 3072MB), size= 1024MB, count=1: uncachable


Many thanks in advance


Kind Regards

Matt
