The system states are referred to as policies, and multiple policies can be loaded onto the system at any given time, however only one policy can be active at a given time. Policy is a combination of PMF input and output capabilities. The inputs are the incoming information from the other kernel subsystems like LID state, Sensor info, GPU info etc and the actions are the updating the power limits of SMU etc. The policy binary is signed and encrypted by a special key from AMD. This policy binary shall have the inputs and outputs which the OEMs can build for the platform customization that can enhance the user experience and system behavior. This series adds the initial support for Smart PC solution to PMF driver. Note that, on platforms where CnQF and Smart PC is advertised, Smart PC shall have higher precedence and same applies for Auto Mode. V1->v2: --------- - Remove __func__ macros - Remove manual function names inside prints - Handle tee_shm_get_va() failure - Remove double _ - Add meaningful prints - pass amd_pmf_set_dram_addr() failure errors - Add more information to commit messages - use right format specifiers - use devm_ioremap() instead of ioremap() - address unsigned long vs u32 problems - Fix lkp reported issues - Add amd_pmf_remove_pb() to remove the debugfs files created(if any). - Make amd_pmf_open_pb() as static. - Add cooling device APIs for controlling amdgpu backlight - handle amd_pmf_apply_policies() failures - Split v1 14/15 into 2 patches further - use linux/units.h for better handling - add "depends on" AMD_SFH_HID for interaction with SFH - other cosmetic remarks Basavaraj Natikar (3): HID: amd_sfh: rename float_to_int() to amd_sfh_float_to_int() platform/x86/amd/pmf: Add PMF-AMDSFH interface for HPD platform/x86/amd/pmf: Add PMF-AMDSFH interface for ALS Shyam Sundar S K (13): platform/x86/amd/pmf: Add PMF TEE interface platform/x86/amd/pmf: Add support PMF-TA interaction platform/x86/amd/pmf: Change return type of amd_pmf_set_dram_addr() platform/x86/amd/pmf: Add support for PMF Policy Binary platform/x86/amd/pmf: change amd_pmf_init_features() call sequence platform/x86/amd/pmf: Add support to get inputs from other subsystems platform/x86/amd/pmf: Add support update p3t limit platform/x86/amd/pmf: Add support to update system state platform/x86/amd/pmf: Add facility to dump TA inputs platform/x86/amd/pmf: Add capability to sideload of policy binary platform/x86/amd/pmf: dump policy binary data platform/x86/amd/pmf: Add PMF-AMDGPU get interface platform/x86/amd/pmf: Add PMF-AMDGPU set interface Documentation/admin-guide/index.rst | 1 + Documentation/admin-guide/pmf.rst | 25 + drivers/gpu/drm/amd/amdgpu/Makefile | 2 + drivers/gpu/drm/amd/amdgpu/amdgpu.h | 1 + drivers/gpu/drm/amd/amdgpu/amdgpu_pmf.c | 154 ++++++ drivers/hid/amd-sfh-hid/amd_sfh_common.h | 6 + drivers/hid/amd-sfh-hid/sfh1_1/amd_sfh_desc.c | 22 +- drivers/hid/amd-sfh-hid/sfh1_1/amd_sfh_init.c | 17 + .../amd-sfh-hid/sfh1_1/amd_sfh_interface.c | 48 ++ .../amd-sfh-hid/sfh1_1/amd_sfh_interface.h | 1 + drivers/platform/x86/amd/pmf/Kconfig | 3 + drivers/platform/x86/amd/pmf/Makefile | 3 +- drivers/platform/x86/amd/pmf/acpi.c | 37 ++ drivers/platform/x86/amd/pmf/core.c | 52 +- drivers/platform/x86/amd/pmf/pmf.h | 201 +++++++ drivers/platform/x86/amd/pmf/spc.c | 197 +++++++ drivers/platform/x86/amd/pmf/sps.c | 2 +- drivers/platform/x86/amd/pmf/tee-if.c | 515 ++++++++++++++++++ include/linux/amd-pmf-io.h | 55 ++ 19 files changed, 1317 insertions(+), 25 deletions(-) create mode 100644 Documentation/admin-guide/pmf.rst create mode 100644 drivers/gpu/drm/amd/amdgpu/amdgpu_pmf.c create mode 100644 drivers/platform/x86/amd/pmf/spc.c create mode 100644 drivers/platform/x86/amd/pmf/tee-if.c create mode 100644 include/linux/amd-pmf-io.h
