Subject: [PATCH 16/39] eal: move core indices bitset to runtime state
Date: Tue, 21 Jul 2026 10:45:24 +0100	[thread overview]
Message-ID: <20260721094555.2188496-17-bruce.richardson@intel.com> (raw)
In-Reply-To: <20260721094555.2188496-1-bruce.richardson@intel.com>

Move the bitset for tracking allocated lcore ids to the runtime
configuration struct, to co-exist with the other lcore data.
