Subject[PATCH 6/6] MIPS: math-emu: Add FP emu debugfs stats for individual instructions
Date
From: Aleksandar Markovic <aleksandar.markovic@imgtec.com>

Add FP emulation debugfs statistics for individual instructions. The
counters are placed in a separate directory called "instructions".
The default full path of this directory is
"/sys/kernel/debug/mips/fpuemustats/instructions"."

One example of usage:

mips_host::/sys/kernel/debug/mips/fpuemustats/instructions # grep "" *

The shortened output of this command is:

abs.d:34
abs.s:5711
add.d:10401
add.s:399307
bc1eqz:3199
...
...
...
sub.s:167211
trunc.l.d:375
trunc.l.s:8054
trunc.w.d:421
trunc.w.s:27032

The limitation of this patch is that it handles R6 FP emulation
instructions only. There are altogether 114 handled instructions.
