/proc/mtrr
This file refers to the current Memory Type Range Registers (MTRRs) in use with the system. If the
system architecture supports MTRRs, then the
reg00: base=0x00000000 (
MTRRs are used with the Intel P6 family of processors (Pentium II and higher) and control processor
access to memory ranges. When using a video card on a PCI or AGP bus, a properly configured
file can increase performance more than 150%.

Most of the time, this value is properly configured by default. More information on manually config-

— The major number of the device with this partition. The major number in our example
• major
