| * | MIPS: Add FPU emulator counter for emulated delay slots. | David Daney | 2015-04-01 |
| | | | | | | | | | | | | Delay slot emulation in the FPU emulator is the only kernel user of an executable stack, it is also very slow. Add a counter so we can see how many of these emulations are done.

| * | MIPS: math-emu: Add IEEE754 exception statistics to debugfs | Deng-Cheng Zhu | 2014-05-30 |
| | | | | | | | | | | | | | | | | | | | | | 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. [ralf@linux-mips.org: Fixed reject due to other changes to the kernel FP assist software.] Signed-off-by: Deng-Cheng Zhu <dengcheng.zhu@imgtec.com> Cc: linux-mips@linux-mips.org Cc: Steven.Hill@imgtec.com Cc: james.hogan@imgtec.com Patchwork: http://patchwork.linux-mips.org/patch/7044/ Signed-off-by: Ralf Baechle <ralf@linux-mips.org> | ||
