# SPDX-License-Identifier: ISC config ATH9K_HW tristate config ATH9K_COMMON tristate select ATH_COMMON config ATH9K_COMMON_DEBUG bool config ATH9K_DFS_DEBUGFS def_bool y depends on ATH9K_DEBUGFS && ATH9K_DFS_CERTIFIED config ATH9K_BTCOEX_SUPPORT bool "Atheros bluetooth coexistence support" depends on (ATH9K || ATH9K_HTC) default y help Say Y, if you want to use the ath9k/ath9k_htc radios together with Bluetooth modules in the same system. config ATH9K tristate "Atheros 802.11n wireless cards support" depends on MAC80211 && HAS_DMA select MAC80211_LEDS if LEDS_CLASS=y || LEDS_CLASS=MAC80211 select ATH9K_HW select ATH9K_COMMON help This module adds support for wireless adapters based on Atheros IEEE 802.11n AR5008, AR9001 and AR9002 family of chipsets. For a specific list of supported external cards, laptops that already ship with these cards and APs that come with these cards refer to ath9k wiki products page: https://wireless.wiki.kernel.org/en/users/Drivers/ath9k/products If you choose to build a module, it'll be called ath9k. config ATH9K_PCI bool "Atheros ath9k PCI/PCIe bus support" default y depends on ATH9K && PCI help This option enables the PCI bus support in ath9k. Say Y, if you have a compatible PCI/PCIe wireless card. config ATH9K_AHB bool "Atheros ath9k AHB bus support" depends on ATH9K default n help This option enables the AHB bus support in ath9k. Say Y, if you have a SoC with a compatible built-in wireless MAC. Say N if unsure. config ATH9K_DEBUGFS bool "Atheros ath9k debugging" depends on ATH9K && DEBUG_FS select MAC80211_DEBUGFS select ATH9K_COMMON_DEBUG help Say Y, if you need access to ath9k's statistics for interrupts, rate control, etc. Also required for changing debug message flags at run time and for TX99. config ATH9K_STATION_STATISTICS bool "Detailed station statistics" depends on ATH9K && ATH9K_DEBUGFS && DEBUG_FS select MAC80211_DEBUGFS default n help This option enables detailed statistics for association stations. config ATH9K_TX99 bool "Atheros ath9k TX99 testing support" depends on ATH9K_DEBUGFS && CFG80211_CERTIFICATION_ONUS default n help Say N. This should only be enabled on systems undergoing certification testing and evaluation in a controlled environment. Enabling this will only enable TX99 support, all other modes of operation will be disabled. TX99 support enables Specific Absorption Rate (SAR) testing. SAR is the unit of measurement for the amount of radio frequency(RF) absorbed by the body when using a wireless device. The RF exposure limits used are expressed in the terms of SAR, which is a measure of the electric and magnetic field strength and power density for transmitters operating at frequencies from 300 kHz to 100 GHz. Regulatory bodies around the world require that wireless device be evaluated to meet the RF exposure limits set forth in the governmental SAR regulations. config ATH9K_DFS_CERTIFIED bool "Atheros DFS support for certified platforms" depends on ATH9K && CFG80211_CERTIFICATION_ONUS default n help This option enables DFS support for initiating radiation on ath9k. There is no way to dynamically detect if a card was DFS certified and as such this is left as a build time option. This option should only be enabled by system integrators that can guarantee that all the platforms that their kernel will run on have obtained appropriate regulatory body certification for a respective Atheros card by using ath9k on the target shipping platforms. This is currently only a placeholder for future DFS support, as DFS support requires more components that still need to be developed. At this point enabling this option won't do anything except increase code size. config ATH9K_DYNACK bool "Atheros ath9k ACK timeout estimation algorithm" depends on ATH9K default n help This option enables ath9k dynamic ACK timeout estimation algorithm based on ACK frame RX timestamp, TX frame timestamp and frame duration config ATH9K_WOW bool "Wake on Wireless LAN support (EXPERIMENTAL)" depends on ATH9K && PM default n help This option enables Wake on Wireless LAN support for certain cards. Currently, AR9462 is supported. config ATH9K_RFKILL bool "Atheros ath9k rfkill support" if EXPERT depends on ATH9K depends on RFKILL=y || RFKILL=ATH9K default y help Say Y to have ath9k poll the RF-Kill GPIO every couple of seconds. Turn off to save power, but enable it if you have a platform that can toggle the RF-Kill GPIO. config ATH9K_CHANNEL_CONTEXT bool "Channel Context support" depends on ATH9K default n help This option enables channel context support in ath9k, which is needed for multi-channel concurrency. Enable this if P2P PowerSave support is required. config ATH9K_PCOEM bool "Atheros ath9k support for PC OEM cards" if EXPERT depends on ATH9K default y config ATH9K_PCI_NO_EEPROM tristate "Atheros ath9k pci loader for EEPROM-less chips" depends on ATH9K_PCI default n help This separate driver provides a loader in order to support the AR500X to AR92XX-generation of ath9k PCI(e) WiFi chips, which have their initialization data (which contains the real PCI Device ID that ath9k will need) stored together with the calibration data out of reach for the ath9k chip. These devices are usually various network appliances, routers or access Points and such. If unsure say N. config ATH9K_HTC tristate "Atheros HTC based wireless cards support" depends on USB && MAC80211 select MAC80211_LEDS if LEDS_CLASS=y || LEDS_CLASS=MAC80211 select ATH9K_HW select ATH9K_COMMON help Support for Atheros HTC based cards. Chipsets supported: AR9271 For more information: https://wireless.wiki.kernel.org/en/users/Drivers/ath9k_htc The built module will be ath9k_htc. config ATH9K_HTC_DEBUGFS bool "Atheros ath9k_htc debugging" depends on ATH9K_HTC && DEBUG_FS select ATH9K_COMMON_DEBUG help Say Y, if you need access to ath9k_htc's statistics. As well as access to the FFT/spectral data. config ATH9K_HWRNG bool "Random number generator support" depends on ATH9K && (HW_RANDOM = y || HW_RANDOM = ATH9K) default n help This option incorporates the ADC register output as a source of randomness into Linux entropy pool (/dev/urandom and /dev/random) Say Y, feeds the entropy directly from the WiFi driver to the input pool. config ATH9K_COMMON_SPECTRAL bool "Atheros ath9k/ath9k_htc spectral scan support" depends on ATH9K_DEBUGFS || ATH9K_HTC_DEBUGFS select RELAY default n help Say Y to enable access to the FFT/spectral data via debugfs.
