Hi John,
Changes in v3:
Rebased onto latest commit 95066b1a1a0a ("cyclicdeadline.c: Fix printf format specifier")
in unstable/devel/latest.
This patch adds the option --mainaffinity to specify the affinity of
the main pid.
This is mainly useful if you want to bind the main thread to a
different (e.g. housekeeping ) CPU than the measurement threads.
Some numbers on potential latency benefits are linked in the
v1 thread at https://lore.kernel.org/linux-rt-users/dd40b81d-7099-7740-c2ad-64b49e582234@xxxxxxxxx/
Regards
Jonathan
