Hi Ben, Kumar,
Finally (after ca. 1.5 years), he're an updated version of my patch
to keep
track of emulated instructions. In the light of Kumar's `Emulate
enough of SPE
instructions to make gcc happy' patch, he probably also wants to
keep track of
the actual runtime overhead.
Changes since last version:
- arch/powerpc/kernel/sysfs.c is now compiled on ppc32, so we can
provide
counters in sysfs on ppc32, too,
- WARN_EMULATED() is a no-op if CONFIG_SYSCTL is disabled,
- Add warnings for altivec,
- Add warnings for recently introduced emulation of vsx and isel
instructions.
pretty cool. Do we think counters should be sysfs or debugfs?
Also it would be nice to be able to zero out the counters.
