Subject: [RFC PATCH v2 10/18] RISC-V: Define irqbypass vcpu_info
Date: Sat, 20 Sep 2025 15:39:00 -0500 [thread overview]
Message-ID: <20250920203851.2205115-30-ajones@ventanamicro.com> (raw)
In-Reply-To: <20250920203851.2205115-20-ajones@ventanamicro.com>
The vcpu_info parameter to irq_set_vcpu_affinity() effectively
defines an arch specific IOMMU <=> hypervisor protocol. Provide
a definition for the RISCV IOMMU.
