For a specific list of supported external 31 cards, laptops that already ship with these cards and 32 APs that come with these cards refer to ath9k wiki 33 products page: 34 35 https://wireless.wiki.kernel.org/en/users/Drivers/ath9k/products 36 37 If you choose to build a module, it'll be called ath9k. 38 39config ATH9K_PCI 40 bool "Atheros ath9k PCI/PCIe bus support" 41 default y 42 depends on ATH9K && PCI 43 help 44 This option enables the PCI bus support in ath9k. 45 46 Say Y, if you have a compatible PCI/PCIe wireless card. 47 48config ATH9K_AHB 49 bool "Atheros ath9k AHB bus support" 50 depends on ATH9K 51 default n 52 help 53 This option enables the AHB bus support in ath9k. 54 55 Say Y, if you have a SoC with a compatible built-in 56 wireless MAC. Say N if unsure. 57 58config ATH9K_DEBUGFS 59 bool "Atheros ath9k debugging" 60 depends on ATH9K && DEBUG_FS 61 select MAC80211_DEBUGFS 62 select ATH9K_COMMON_DEBUG 63 help 64 Say Y, if you need access to ath9k's statistics for 65 interrupts, rate control, etc. 66 67 Also required for changing debug message flags at run time and for 68 TX99. 69 70config ATH9K_STATION_STATISTICS 71 bool "Detailed station statistics" 72 depends on ATH9K && ATH9K_DEBUGFS && DEBUG_FS 73 select MAC80211_DEBUGFS 74 default n 75 help 76 This option enables detailed statistics for association stations. 77 78config ATH9K_TX99 79 bool "Atheros ath9k TX99 testing support" 80 depends on ATH9K_DEBUGFS && CFG80211_CERTIFICATION_ONUS 81 default n 82 help 83 Say N. This should only be enabled on systems undergoing 84 certification testing and evaluation in a controlled environment. 85 Enabling this will only enable TX99 support, all other modes of 86 operation will be disabled. 87 88 TX99 support enables Specific Absorption Rate (SAR) testing. 89 SAR is the unit of measurement for the amount of radio frequency(RF) 90 absorbed by the body when using a wireless device. The RF exposure 91 limits used are expressed in the terms of SAR, which is a measure 92 of the electric and magnetic field strength and power density for 93 transmitters operating at frequencies from 300 kHz to 100 GHz. 94 Regulatory bodies around the world require that wireless device 95 be evaluated to meet the RF exposure limits set forth in the 96 governmental SAR regulations. 97 98config ATH9K_DFS_CERTIFIED 99 bool "Atheros DFS support for certified platforms" 100 depends on ATH9K && CFG80211_CERTIFICATION_ONUS 101 default n 102 help 103 This option enables DFS support for initiating radiation on 104 ath9k. There is no way to dynamically detect if a card was DFS 105 certified and as such this is left as a build time option. This 106 option should only be enabled by system integrators that can 107 guarantee that all the platforms that their kernel will run on 108 have obtained appropriate regulatory body certification for a 109 respective Atheros card by using ath9k on the target shipping 110 platforms. 111 112 This is currently only a placeholder for future DFS support, 113 as DFS support requires more components that still need to be 114 developed. At this point enabling this option won't do anything 115 except increase code size. 116 117config ATH9K_DYNACK 118 bool "Atheros ath9k ACK timeout estimation algorithm" 119 depends on ATH9K 120 default n 121 help 122 This option enables ath9k dynamic ACK timeout estimation algorithm 123 based on ACK frame RX timestamp, TX frame timestamp and frame 124 duration 125 126config ATH9K_WOW 127 bool "Wake on Wireless LAN support (EXPERIMENTAL)" 128 depends on ATH9K && PM 129 default n 130 help 131 This option enables Wake on Wireless LAN support for certain cards. 132 Currently, AR9462 is supported. 133 134config ATH9K_RFKILL 135 bool "Atheros ath9k rfkill support" if EXPERT 136 depends on ATH9K 137 depends on RFKILL=y || RFKILL=ATH9K 138 default y 139 help 140 Say Y to have ath9k poll the RF-Kill GPIO every couple of 141 seconds. Turn off to save power, but enable it if you have 142 a platform that can toggle the RF-Kill GPIO. 143 144config ATH9K_CHANNEL_CONTEXT 145 bool "Channel Context support" 146 depends on ATH9K 147 default n 148 help 149 This option enables channel context support in ath9k, which is needed 150 for multi-channel concurrency. Enable this if P2P PowerSave support 151 is required. 152 153config ATH9K_PCOEM 154 bool "Atheros ath9k support for PC OEM cards" if EXPERT 155 depends on ATH9K 156 default y 157 158config ATH9K_PCI_NO_EEPROM 159 tristate "Atheros ath9k pci loader for EEPROM-less chips" 160 depends on ATH9K_PCI 161 default n 162 help 163 This separate driver provides a loader in order to support the 164 AR500X to AR92XX-generation of ath9k PCI(e) WiFi chips, which have 165 their initialization data (which contains the real PCI Device ID 166 that ath9k will need) stored together with the calibration data out 167 of reach for the ath9k chip. 168 169 These devices are usually various network appliances, routers or 170 access Points and such. 171 172 If unsure say N. 173 174config ATH9K_HTC 175 tristate "Atheros HTC based wireless cards support" 176 depends on USB && MAC80211 177 select MAC80211_LEDS if LEDS_CLASS=y || LEDS_CLASS=MAC80211 178 select ATH9K_HW 179 select ATH9K_COMMON 180 help 181 Support for Atheros HTC based cards. 182 Chipsets supported: AR9271 183 184 For more information: 185 https://wireless.wiki.kernel.org/en/users/Drivers/ath9k_htc 186 187 The built module will be ath9k_htc. 188 189config ATH9K_HTC_DEBUGFS 190 bool "Atheros ath9k_htc debugging" 191 depends on ATH9K_HTC && DEBUG_FS 192 select ATH9K_COMMON_DEBUG 193 help 194 Say Y, if you need access to ath9k_htc's statistics. 195 As well as access to the FFT/spectral data. 196 197config ATH9K_HWRNG 198 bool "Random number generator support" 199 depends on ATH9K && (HW_RANDOM = y || HW_RANDOM = ATH9K) 200 default n 201 help 202 This option incorporates the ADC register output as a source of 203 randomness into Linux entropy pool (/dev/urandom and /dev/random) 204 205 Say Y, feeds the entropy directly from the WiFi driver to the input 206 pool. 207 208config ATH9K_COMMON_SPECTRAL 209 bool "Atheros ath9k/ath9k_htc spectral scan support" 210 depends on ATH9K_DEBUGFS || ATH9K_HTC_DEBUGFS 211 select RELAY 212 default n 213 help 214 Say Y to enable access to the FFT/spectral data via debugfs.
