From 164ecbf73c3ea61455e07eefdad8050a7b569558 Mon Sep 17 00:00:00 2001 From: Sascha Bischoff Date: Tue, 7 Oct 2025 15:48:54 +0000 Subject: [PATCH] Documentation: KVM: Update GICv3 docs for GICv5 hosts GICv5 hosts optionally include FEAT_GCIE_LEGACY, which allows them to execute GICv3-based VMs on GICv5 hardware. Update the GICv3 documentation to reflect this now that GICv3 guests are supports on compatible GICv5 hosts.
