Subject: [PATCH 1/4] NTB: ntb_perf: Increased the number of message retries to 1000
Date: Fri, 15 Feb 2019 09:20:07 +0000 [thread overview]
Message-ID: <1550222279-27216-1-git-send-email-Sanju.Mehta@amd.com> (raw)
From: Sanjay R Mehta <sanju.mehta@amd.com>
while waiting for the peer ntb_perf to initialize scratchpad
registers, local side ntb_perf might have already exhausted the
maximum number of retries which is currently set to 500. To avoid
this and to give little more time to the peer ntb_perf for scratchpad
initialization, increased the number of retries to 1000
