Subject: [dpdk-stable] [PATCH 19.11.9] eal/windows: fix default thread priority
Date: Sun, 23 May 2021 11:12:42 +0300 [thread overview]
Message-ID: <20210523081242.19860-1-talshn@nvidia.com> (raw)
[ upstream commit 16afcbfa30e9c2831264fb349457a4228fa687c8 ]
The hard-coded thread priority for Windows threads in EAL
is REALTIME_PRIORITY_CLASS/THREAD_PRIORITY_TIME_CRITICAL.
This results in issues with DPDK threads causing OS thread starvation
and eventually a bugcheck.
The fix reduce the thread priority to
NORMAL_PRIORITY_CLASS/THREAD_PRIORITY_NORMAL.
Bugzilla ID: 600
Reported-by: Odi Assli <odia@nvidia.com>
