Subject: [PATCH v2 2/3] ACPI: scan: Add support for RISC-V in acpi_iommu_configure_id()
Date: Tue, 10 Jun 2025 16:16:40 +0530	[thread overview]
Message-ID: <20250610104641.700940-3-sunilvl@ventanamicro.com> (raw)
In-Reply-To: <20250610104641.700940-1-sunilvl@ventanamicro.com>

acpi_iommu_configure_id() currently supports only IORT (ARM) and VIOT.
Add support for RISC-V as well.
