Subject: [PATCH 36/60] kvm: Add plane_level to kvm_kernel_irq_routing_entry
Date: Mon,  8 Jun 2026 16:42:28 +0200	[thread overview]
Message-ID: <20260608144252.351443-37-joro@8bytes.org> (raw)
In-Reply-To: <20260608144252.351443-1-joro@8bytes.org>

From: Joerg Roedel <joerg.roedel@amd.com>

Track the target plane-level of MSI irqs in struct
kvm_kernel_irq_routing_entry. This will be used to send MSI IRQs to
the right plane-level once planes are supported.

Signed-off-by: Joerg Roedel <joerg.roedel@amd.com>
