Subject: [PATCH 0/5] IB/hfi1: sdma engine affinity improvements
Date: Sun, 25 Sep 2016 07:44:15 -0700 [thread overview]
Message-ID: <20160925144248.12088.71489.stgit@scvm10.sc.intel.com> (raw)
This patch series is a set of performance improvements that deal with handling
the affinity of sdma engines. This allows users more control over which CPU
cores are used by the driver for sdma engines. It includes a way to dump out the
current values and a handler for when the user changes irq affinity. The changes
to sysfs are also documented.
This applies on top of the last series submitted and can be seen in my GitHub:
