I only scanned briefly through this patchset, but I didn't see any code implementing: * KVM_DEV_ARM_VGIC_GRP_LEVEL_INFO * the different behaviour for accesses to GICD_STATUSR, GICR_STATUSR, GICD_ISPENDR, GICR_ISPENDR0, GICD_ICPENDR, and GICR_ICPENDR0, which don't act the same via this API as for a guest access to the register Did I miss something? thanks -- PMM _______________________________________________ kvmarm mailing list kvmarm@xxxxxxxxxxxxxxxxxxxxx https://lists.cs.columbia.edu/mailman/listinfo/kvmarm
