[PATCH v2 0/2] RISC-V: ACPI: Add support for RIMT

Posted by Sunil V L 10 months, 3 weeks ago

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].

[1] - https://github.com/riscv-non-isa/riscv-acpi-rimt/releases/download/v0.99/rimt-spec.pdf

Changes since v1:
	1) Used g_autoptr as per Daniel's suggestion.
	2) Added R-b tag from Daniel.
