Subject: [edk2-platforms][PATCH V1 00/17] Enable idle state and CPPC support for RD platform
Date: Wed, 28 Apr 2021 18:05:43 +0530 [thread overview]
Message-ID: <20210428123600.2385-1-pranav.madhu@arm.com> (raw)
Low Power Idle (LPI) and Collaborative Processor Performance Control
(CPPC) are two power management mechanisms described in ACPI 6.4
specification. OSPM uses the _LPI object to select a local power state
for each level of processor hierarchy in the system. Collaborative
processor performance control (CPPC) defines an abstracted and flexible
mechanism for OSPM to collaborate with an entity in the platform to
manage the performance of a processor. In this patch series, CPPC
support depends on the availability of Activity Monitor Unit (AMU)
extension for CPU performance monitoring as defined in the Arm v8.4
architecture reference manuals. So CPPC is supported for RD-V1 and
RD-N2 platforms.
This patch series adds LPI support for all the Neoverse reference
design platforms. CPPC support is added for RD-V1, RD-V1-MC and
RD-N2 platforms.
This patch series should be applied on top of the patch series
