- Description
- The maxpmem parameter specifies the amount of physical memory (in pages) that the system can recognize. The page size is 4 Kilobytes for 32 bit IRIX version 5 or 6 kernels and 16 Kilobytes for 64 bit IRIX version 6 kernels. If set to zero (0), the system will use all available pages in memory. A value other than zero defines the physical memory size (in pages) that the system will recognize.
This parameter is defined in /var/sysgen/mtune.
- Value
- Default: 0 (Automatically configured if set to 0)
Range: 1024 pages - total amount of memory
- When to Change
-
You don't need to change this parameter, except when benchmarks require a specific system memory size less than the physical memory size of the system. This is primarily useful to kernel developers. You can also boot the system with the command:
maxpmem = memory_size
added on the boot command line to achieve the same effect.
