Subject: [PATCH 0/2] RISC-V: ACPI: Add support for RIMT
Date: Fri, 14 Mar 2025 10:45:25 +0530	[thread overview]
Message-ID: <20250314051527.1892488-1-sunilvl@ventanamicro.com> (raw)

RISC-V IO Mapping Table (RIMT) is a new static ACPI table used to
communicate IOMMU and topology information to the OS. Add support for
creating this table when the IOMMU is present. The specification is
frozen and available at [1].
