[edk2] [PATCH edk2-platforms v1 2/6] Platform/ARM: Dynamic Tables support for Juno

Sami Mujawar sami.mujawar at arm.com
Fri Dec 21 09:00:17 PST 2018


The dynamic tables framework uses the platform hardware
information described by the configuration manager to
generate ACPI tables. This support is configurable and
can be enabled using the DYNAMIC_TABLES_FRAMEWORK build
option.

When DYNAMIC_TABLES_FRAMEWORK is defined, ACPI tables are
generated and installed by the dynamic table framework.
Therefore, installation of ACPI tables from the Firmware
Volume (FV) is disabled by this option.
