Subject: [dpdk-dev] [PATCH v2 08/15] test/rcu: remove arbitrary limit on max core count
Date: Sat, 15 Jun 2019 08:42:23 +0200
Message-ID: <1560580950-16754-9-git-send-email-david.marchand@redhat.com> (raw)
In-Reply-To: <1560580950-16754-1-git-send-email-david.marchand@redhat.com>

We can have up to RTE_MAX_LCORE in a dpdk application.
Remove the limit on 128 cores and tests that are now always false.

Fixes: b87089b0bb19 ("test/rcu: add API and functional tests")
Cc: stable@dpdk.org

Signed-off-by: David Marchand <david.marchand@redhat.com>

Changelog since v1:
- new patch added to remove the local TEST_RCU_MAX_LCORE limit
- changed some integer types to accomodate with the change
