From cf1bb5e566ad0e346af810b399d871a74031feb2 Mon Sep 17 00:00:00 2001 From: Ian Moffett Date: Fri, 25 Jul 2025 02:44:11 -0400 Subject: kernel/amd64: Keep track of which cores are online Give each core a bit that indicates whether the core is online or halted. We also provide a cpu_halt() which marks the core as offline.
