numa=noacpi Don't parse the SRAT table for NUMA setup
- numa=fake=X Fake X nodes and ignore NUMA setup of the actual machine.
+ numa=fake=CMDLINE
+ If a number, fakes CMDLINE nodes and ignores NUMA setup of the
+ actual machine. Otherwise, system memory is configured
+ depending on the sizes and coefficients listed. For example:
+ numa=fake=2*512,1024,4*256
+ gives two 512M nodes, a 1024M node, and four 256M nodes. The
+ remaining system RAM is allocated to an additional node.
numa=hotadd=percent
Only allow hotadd memory to preallocate page structures upto
stuck (default)

- noreplacement Don't replace instructions with more appropriate ones
- for the CPU. This may be useful on asymmetric MP systems
- where some CPUs have less capabilities than others.
