| D | mtrr.txt | 51 The CONFIG_MTRR option creates a /proc/mtrr file which may be used
58 There are two interfaces to /proc/mtrr: one is an ASCII interface
67 % cat /proc/mtrr
72 # echo "base=0xf8000000 size=0x400000 type=write-combining" >! /proc/mtrr
74 # echo "base=0xf8000000 size=0x400000 type=write-combining" >| /proc/mtrr
77 % cat /proc/mtrr
100 in other words the X server will manipulate /proc/mtrr using the
106 %echo "base=0xfb000000 size=0x1000000 type=write-combining" >/proc/mtrr
107 %echo "base=0xfb000000 size=0x1000 type=uncachable" >/proc/mtrr
109 And the results: cat /proc/mtrr
