Subject: [profile] Add profile_custom() for profiling with arbitrary time units
X-Git-Tag: v1.20.1~778
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=6bc3d994966b00560e07c662b33da0cc9477891f;p=thirdparty%2Fipxe.git

[profile] Add profile_custom() for profiling with arbitrary time units

Provide profile_custom() as a trivial wrapper around profile_update()
to allow for the use of the profiling infrastructure by code using
timers other than the default profile_timestamp() provider.
