Subject: [PATCH v2 22/22] DynamicTablesPkg: Arm IORT Table Generator
Date: Thu, 24 Jan 2019 15:44:36 +0000 [thread overview]
Message-ID: <20190124154436.21996-23-sami.mujawar@arm.com> (raw)
In-Reply-To: <20190124154436.21996-1-sami.mujawar@arm.com>
The IORT generator uses the configuration manager protocol
to obtain information about the PCI Root Complex, SMMU,
GIC ITS, Performance Monitoring counters etc. and generates
the IORT table.
The mappings between the components are represented using
tokens. The generator invokes the configuration manager
protocol interfaces and requests for objects referenced by
tokens to establish the link.
This table data is then used by the Table Manager to install
the IORT table.
The Table Manager then invokes the generator interface to free
any resources allocated by the IORT table generator.
