[PATCH 5/5] irqchip/gic-v5: Drop has_gcie_v3_compat from gic_kvm_info
From: Sascha Bischoff <hidden>
Date: 2025-08-28 11:00:19
Also in:
kvm, kvmarm, lkml
Subsystem:
arm generic interrupt controller drivers, arm generic interrupt controller v5 drivers, irqchip drivers, the rest · Maintainers:
Marc Zyngier, Lorenzo Pieralisi, Thomas Gleixner, Linus Torvalds
The presence of FEAT_GCIE_LEGACY is now handled as a CPU feature. Therefore, drop the check and flag from the GIC driver and gic_kvm_info as it is no longer required or used by KVM.
