From: Kalle Valo <quic_kvalo@xxxxxxxxxxx> Through reading ACPI tables, implement Time-Average-SAR(TAS), BIOS SAR, configuration of CCA threshold and band edge channel power functionalities. This is enabled only on WCN7850. TODO: * test with ACPI support in hardware (I don't have such hardware), especially suspend and hibernation v8: * rebase to ath-202404181528 * rewrite commit messages * cleanup and improvements all over to match the ath12k style, including error handling, naming and so on * locate new place to call ath12k_acpi_[start|stop]() * move wmi functions up in wmi.c file * consolidate WMI functions using WMI_PDEV_SET_BIOS_INTERFACE_CMDID into ath12k_wmi_set_bios_cmd() * ath12k_acpi_stop(): don't call acpi_remove_notify_handler() if we never installed the handler v7: https://patchwork.kernel.org/project/linux-wireless/cover/20231013114434.81648-1-quic_lingbok@xxxxxxxxxxx/ * adjust the length of line * add cpu_to_le32() v6: * remove code that is not called v5: * rebase to the latest tag v4: * revise commit log using imperative voice * delete guid_is_null() v3: * remove unnecessary cpu_to_le32() * adjust the order of the macros * apply jeff's advice v2: * put <linux/acpi.h> in the include guard Lingbo Kong (4): wifi: ath12k: ACPI TAS support wifi: ath12k: ACPI SAR support wifi: ath12k: ACPI CCA threshold support wifi: ath12k: ACPI band edge channel power support drivers/net/wireless/ath/ath12k/Makefile | 1 + drivers/net/wireless/ath/ath12k/acpi.c | 394 +++++++++++++++++++++++ drivers/net/wireless/ath/ath12k/acpi.h | 76 +++++ drivers/net/wireless/ath/ath12k/core.c | 7 + drivers/net/wireless/ath/ath12k/core.h | 18 ++ drivers/net/wireless/ath/ath12k/hw.c | 10 + drivers/net/wireless/ath/ath12k/hw.h | 3 + drivers/net/wireless/ath/ath12k/wmi.c | 143 ++++++++ drivers/net/wireless/ath/ath12k/wmi.h | 41 +++ 9 files changed, 693 insertions(+) create mode 100644 drivers/net/wireless/ath/ath12k/acpi.c create mode 100644 drivers/net/wireless/ath/ath12k/acpi.h base-commit: c416602943dd36fbd13af7496430723935c867a3 -- 2.39.2
