From: Harry van Haaren Date: Tue, 16 Jun 2020 16:56:03 +0000 (+0100) Subject: examples/eventdev: fix 32-bit coremask X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=ff0f1040b66edcbaf93fc217ea452e4a9ae424e2;p=dpdk.git examples/eventdev: fix 32-bit coremask This commit fixes a bug in 32-bit environments when a core mask greater than 32-bits is requested. The fix is to convert the bitmask logic to 64 bits, aligning 64 and 32 bit implementations.
