Subject: [PATCH 2/3] x86/defconfig: add CONFIG_IRQ_REMAP
Date: Mon, 02 Feb 2026 18:51:03 +0900 [thread overview]
Message-ID: <20260202-x2apic-fix-v1-2-71c8f488a88b@sony.com> (raw)
In-Reply-To: <20260202-x2apic-fix-v1-0-71c8f488a88b@sony.com>
Interrupt remapping is an architectural dependency of x2apic, which is already
enabled in the defconfig. Enable CONFIG_IRQ_REMAP so that a defconfig kernel on
bare metal actually uses x2apic.
