Subject: [PATCH 08/10] test-pmd: declare lcore_count atomic when using C11 memory model
Date: Tue, 11 Feb 2025 14:02:04 -0800 [thread overview]
Message-ID: <1739311325-14425-9-git-send-email-andremue@linux.microsoft.com> (raw)
In-Reply-To: <1739311325-14425-1-git-send-email-andremue@linux.microsoft.com>
Compiling with MSVC results in the error below:
app/test/test_ring_perf.c(197): error C7712: address argument to atomic
operation must be a pointer to an atomic integer,
'volatile unsigned int *' is not valid
The fix is to mark lcore_count as atomic when using C11 memory model.
