Subject: [PATCH] MIPS: Add CPU option reporting to /proc/cpuinfo
|
|
|
|
Many MIPS CPUs have optional CPU features which are not activates for
|
|
all CPU cores. Print the CPU options which are implemented in the core
|
|
in /proc/cpuinfo. This makes it possible to see what features are
|
|
supported and which are not supported. This should cover all standard
|
|
MIPS extensions, before it only printed information about the main MIPS
|
|
ASEs.
