Subject: [PATCH v1 00/11] DynamicTablesPkg: Enable _PSD/_CPC generation using SCMI
Date: Fri, 5 May 2023 15:17:10 +0200 [thread overview]
Message-ID: <20230505131721.1310590-1-pierre.gondois@arm.com> (raw)
From: Pierre Gondois <pierre.gondois@arm.com>
The SCMI performance protocol allows to query the Operating Performance
Points (OPPs) available for each performance domain. Each OPP has a
specific frequency/power consumption/performance.
On Device Tree (DT) based platforms, the SCMI protocol is directly available
from the OS.
On ACPI based platforms, the _PSD objects allows to identify CPUs belonging
to the same performance domain. CPUs belonging to the same performance
domain have the same frequency. The _CPC object allows to describe/control
the performance level/frequency of a CPU (i.e. its frequency).
This patchset:
- Add support for 'DescribeFastchannel' SCMI performance protocol
- Add a object to the DynamicTablesPkg to describe the PSD information
- Allows to generate _PSD objects in the SsdtCpuTopologyGenerator
- Add a ArmScmiInfoLib library populating DynamicTablesPkg CPC objects,
relying on the SCMI protocol to fetch the relevant information
A patchset for Juno-r2 platforms will be submitted to demonstrate
this functionality.
Pierre Gondois (11):
ArmPkg/ArmScmiDxe: Rename PERFORMANCE_PROTOCOL_VERSION
ArmPkg/ArmScmiDxe: Add PERFORMANCE_DESCRIBE_FASTCHANNEL support
MdePkg/Acpi64: Add _PSD/_CPC/State Coordination Types macros
DynamicTablesPkg: Use new CPC revision macro
DynamicTablesPkg: Rename AmlCpcInfo.h to AcpiObjects.h
DynamicTablesPkg: Add CM_ARM_PSD_INFO object
DynamicTablesPkg: Add PsdToken field to CM_ARM_GICC_INFO object
DynamicTablesPkg: Add AmlCreatePsdNode() to generate _PSD
DynamicTablesPkg: Generate _PSD in SsdtCpuTopologyGenerator
DynamicTablesPkg: Add ArmScmiInfoLib
DynamicTablesPkg: Remove check for _CPC field
