MacOS guest with GPU passthrough KVM ioapic issue

Software & Operating Systems VFIO
1

Hi all,

I am using a macos sierra virtual machine from few years on fedora host with passed nvidia gpu.
I notice that after kernel version 5.5.19 the machine can not boot and hangs on the lading screen.
I done some research and in the end find that for my case the problem was in this change:

  • if (edge && kvm_apicv_activated(ioapic->kvm))
    ioapic_lazy_update_eoi(ioapic, irq);

In ioapic.c file (/[arch/x86/kvm/ioapic.c)

I try with different version of macos for example catalina and amd gpu but the issue was still reproducible the vm just hang on apple logo.

So I downloaded the kernel source commented the problematic lazy update function and after rebuilding and booting with my custom kernel the issue was resolved.

I am pretty new to Linux kernel so can some one help me to understand what is the correct way of handling this issue and how to find more information relevant to debugging it.

I assume the ioapic_lazy_update_eoi function will be very simple for someone having knowledge for kvm internals but for me it is pretty hard to understand.

this seems to the be problematic function:

static void ioapic_lazy_update_eoi(struct kvm_ioapic *ioapic, int irq)
{
	int i;
	struct kvm_vcpu *vcpu;
	union kvm_ioapic_redirect_entry *entry = &ioapic->redirtbl[irq];

	kvm_for_each_vcpu(i, vcpu, ioapic->kvm) {
		if (!kvm_apic_match_dest(vcpu, NULL, APIC_DEST_NOSHORT,
					 entry->fields.dest_id,
					 entry->fields.dest_mode) ||
		    kvm_apic_pending_eoi(vcpu, entry->fields.vector))
			continue;

		/*
		 * If no longer has pending EOI in LAPICs, update
		 * EOI for this vetor.
		 */
		rtc_irq_eoi(ioapic, vcpu, entry->fields.vector);
		kvm_ioapic_update_eoi_one(vcpu, ioapic,
					  entry->fields.trig_mode,
					  irq);
		break;
	}
}
