Subject: [PATCH v2] Convert tasklet to per-cpu tasklet.
Date: Thu, 25 Aug 2016 15:23:56 -0400 [thread overview]
Message-ID: <1472153041-14220-1-git-send-email-konrad.wilk@oracle.com> (raw)
Hey,
Dusting of this patchset which had been languishing
in my queue.
The presentation at XPDS 2016 by Intel poked me to brush this off.
The Intel folks have run guests with large amount of CPUs and have
discovered that the spinlock on the tasklet ends up taking an
quite large time. This patchset should fix this problem - and it had
fixed it for me when I tried to run benchmarks that used the
tasklet infrastructure.
The patches are also at:
