| H A D | bL_switcher.h | diff d08e2e09042bd3f7ef66a35cb4bb92794ab26bb2 Wed Feb 13 10:20:44 CST 2013 Dave Martin <dave.martin@linaro.org> ARM: bL_switcher: Add query interface to discover CPU affinities
When the switcher is active, there is no straightforward way to
figure out which logical CPU a given physical CPU maps to.
This patch provides a function
bL_switcher_get_logical_index(mpidr), which is analogous to
get_logical_index().
This function returns the logical CPU on which the specified
physical CPU is grouped (or -EINVAL if unknown).
If the switcher is inactive or not present, -EUNATCH is returned instead.
