| H A D | Makefile | e704f93a Mon Jun 16 16:58:32 CDT 2014 David Riley <davidriley@chromium.org> kernel: time: Add udelay_test module to validate udelay
Create a module that allows udelay() to be executed to ensure that
it is delaying at least as long as requested (with a little bit of
error allowed).
There are some configurations which don't have reliably udelay
due to using a loop delay with cpufreq changes which should use
a counter time based delay instead. This test aims to identify
those configurations where timing is unreliable.
