From bcf92fbca6055b7b717c3706e4e5f92a4e63ef45 Mon Sep 17 00:00:00 2001 From: Shashank Balaji Date: Fri, 6 Mar 2026 14:46:29 +0900 Subject: [PATCH] x86/64/defconfig: Add CONFIG_IRQ_REMAP MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit x2apic is enabled in the defconfig, and interrupt remapping is an architectural dependency of x2apic as per the Intel SDM: Routing of device interrupts to local APIC units operating in x2APIC mode requires use of the interrupt-remapping architecture specified in the Intel® Virtualization Technology for Directed I/O (Revision 1.3 and/or later versions). Enable CONFIG_IRQ_REMAP in defconfig so that a defconfig kernel on bare metal actually uses x2apic.
