The goal of the driver is to enhance end user experience by making AMD PCs smarter, quieter, power efficient by adapting to user behavior and environment. The larger goals include: - Enable easy customization of smart PC solutions by OEMs. - Provide a framework for OEMs to add in custom algorithms and solutions - Improve standby and dynamic platform power through active power management of platform devices. In this series, support for following features has been added. - "Static Power Slider" meant to manage the power budget based on the power modes or the slider position. - "Auto Mode" tracks the moving power average of the APU and takes intelligent decisions to switch between different modes. Signed-off-by: Shyam Sundar S K v4: ----------- - Remove duplicate variables in auto_mode_mode_config() structure - call apmf_event_handler() handler manually so that we don't miss out any notifies - Misc. error handling. v3: ----------- - Cleanup ACPI code path - Optimize metrics table collection mechanism - Avoid races between the acpi handler and the metrics table worker thread. - Remove redundant structures and functions. - Improve the code handling the apmf handler routine. v2 Resend: ----------- - Patches from 9 to 11 were not sent due to wrong email address. Hence resending. v1->v2: ------- - optimize the ACPI path by having a common routine apmf_if_call_store_buffer() - Simply Static slider interaction with platform_profile - Remove CONFIG_DEBUG_FS stub code - Drop changes introduced in platform_profile_get() - Drop CnQF support. Will be sent as a patch-set later. - Other code improvements Shyam Sundar S K (11): platform/x86/amd/pmf: Add support for PMF core layer platform/x86/amd/pmf: Add support for PMF APCI layer platform/x86/amd/pmf: Add support SPS PMF feature platform/x86/amd/pmf: Add debugfs information platform/x86/amd/pmf: Add heartbeat signal support platform/x86/amd/pmf: Add fan control support platform/x86/amd/pmf: Get performance metrics from PMFW platform/x86/amd/pmf: Add support for Auto mode feature platform/x86/amd/pmf: Handle AMT and CQL events for Auto mode platform/x86/amd/pmf: Force load driver on older supported platforms MAINTAINERS: Add AMD PMF driver entry MAINTAINERS | 7 + drivers/platform/x86/amd/Kconfig | 2 + drivers/platform/x86/amd/Makefile | 1 + drivers/platform/x86/amd/pmf/Kconfig | 15 + drivers/platform/x86/amd/pmf/Makefile | 9 + drivers/platform/x86/amd/pmf/acpi.c | 287 +++++++++++++++++ drivers/platform/x86/amd/pmf/auto-mode.c | 301 ++++++++++++++++++ drivers/platform/x86/amd/pmf/core.c | 385 +++++++++++++++++++++++ drivers/platform/x86/amd/pmf/pmf.h | 329 +++++++++++++++++++ drivers/platform/x86/amd/pmf/sps.c | 149 +++++++++ 10 files changed, 1485 insertions(+) create mode 100644 drivers/platform/x86/amd/pmf/Kconfig create mode 100644 drivers/platform/x86/amd/pmf/Makefile create mode 100644 drivers/platform/x86/amd/pmf/acpi.c create mode 100644 drivers/platform/x86/amd/pmf/auto-mode.c create mode 100644 drivers/platform/x86/amd/pmf/core.c create mode 100644 drivers/platform/x86/amd/pmf/pmf.h create mode 100644 drivers/platform/x86/amd/pmf/sps.c -- 2.25.1
