From c410352699e2a1adc77969f19eb63030e610d048 Mon Sep 17 00:00:00 2001 From: Deng-Cheng Zhu Date: Thu, 29 May 2014 12:26:45 -0700 Subject: [PATCH] MIPS: math-emu: Add IEEE754 exception statistics to debugfs Sometimes it's useful to let the user, while doing performance research, know what in the IEEE754 exceptions has caused many times of FP emulation when running a specific application. This patch adds 5 more files to /sys/kernel/debug/mips/fpuemustats/, whose filenames begin with "ieee754". These stats are in addition to the existing cp1ops, cp1xops, errors, loads and stores, which may not be useful in understanding the reasons of ieee754 exceptions.
