Subject: [PATCH 0/4] RISC-V: Add ACPI support for IOMMU
Date: Wed, 14 May 2025 11:27:19 +0530 [thread overview]
Message-ID: <20250514055723.1328557-1-sunilvl@ventanamicro.com> (raw)
This series adds support for RISC-V IOMMU on ACPI based platforms.
RISC-V IO Mapping Table (RIMT) is a new static ACPI table [1] introduced
to communicate IOMMU information to the OS.
The first patch in the series is a ACPICA patch which is already
available in linux-next but included in this series for completeness
only.
