13 config ATH9K_BTCOEX_SUPPORT
14 bool "Atheros bluetooth coexistence support"
15 depends on (ATH9K || ATH9K_HTC)
18 Say Y, if you want to use the ath9k/ath9k_htc radios together with
19 Bluetooth modules in the same system.
22 tristate "Atheros 802.11n wireless cards support"
23 depends on MAC80211 && HAS_DMA
24 select MAC80211_LEDS if LEDS_CLASS=y || LEDS_CLASS=MAC80211
28 This module adds support for wireless adapters based on
29 Atheros IEEE 802.11n AR5008, AR9001 and AR9002 family
30 of chipsets. 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
35 https://wireless.wiki.kernel.org/en/users/Drivers/ath9k/products
37 If you choose to build a module, it'll be called ath9k.
40 bool "Atheros ath9k PCI/PCIe bus support"
42 depends on ATH9K && PCI
44 This option enables the PCI bus support in ath9k.
46 Say Y, if you have a compatible PCI/PCIe wireless card.
49 bool "Atheros ath9k AHB bus support"
53 This option enables the AHB bus support in ath9k.
55 Say Y, if you have a SoC with a compatible built-in
56 wireless MAC. Say N if unsure.
59 bool "Atheros ath9k debugging"
60 depends on ATH9K && DEBUG_FS && MAC80211_DEBUGFS
61 select ATH9K_COMMON_DEBUG
63 Say Y, if you need access to ath9k's statistics for
64 interrupts, rate control, etc.
66 Also required for changing debug message flags at run time and for
69 config ATH9K_STATION_STATISTICS
70 bool "Detailed station statistics"
71 depends on ATH9K && ATH9K_DEBUGFS && DEBUG_FS
74 This option enables detailed statistics for association stations.
77 bool "Atheros ath9k TX99 testing support"
78 depends on ATH9K_DEBUGFS && CFG80211_CERTIFICATION_ONUS
81 Say N. This should only be enabled on systems undergoing
82 certification testing and evaluation in a controlled environment.
83 Enabling this will only enable TX99 support, all other modes of
84 operation will be disabled.
86 TX99 support enables Specific Absorption Rate (SAR) testing.
87 SAR is the unit of measurement for the amount of radio frequency(RF)
88 absorbed by the body when using a wireless device. The RF exposure
89 limits used are expressed in the terms of SAR, which is a measure
90 of the electric and magnetic field strength and power density for
91 transmitters operating at frequencies from 300 kHz to 100 GHz.
92 Regulatory bodies around the world require that wireless device
93 be evaluated to meet the RF exposure limits set forth in the
94 governmental SAR regulations.
96 config ATH9K_DFS_CERTIFIED
97 bool "Atheros DFS support for certified platforms"
98 depends on ATH9K && CFG80211_CERTIFICATION_ONUS
101 This option enables DFS support for initiating radiation on
102 ath9k. There is no way to dynamically detect if a card was DFS
103 certified and as such this is left as a build time option. This
104 option should only be enabled by system integrators that can
105 guarantee that all the platforms that their kernel will run on
106 have obtained appropriate regulatory body certification for a
107 respective Atheros card by using ath9k on the target shipping
110 This is currently only a placeholder for future DFS support,
111 as DFS support requires more components that still need to be
112 developed. At this point enabling this option won't do anything
113 except increase code size.
116 bool "Atheros ath9k ACK timeout estimation algorithm"
120 This option enables ath9k dynamic ACK timeout estimation algorithm
121 based on ACK frame RX timestamp, TX frame timestamp and frame
125 bool "Wake on Wireless LAN support (EXPERIMENTAL)"
126 depends on ATH9K && PM
129 This option enables Wake on Wireless LAN support for certain cards.
130 Currently, AR9462 is supported.
133 bool "Atheros ath9k rfkill support" if EXPERT
135 depends on RFKILL=y || RFKILL=ATH9K
138 Say Y to have ath9k poll the RF-Kill GPIO every couple of
139 seconds. Turn off to save power, but enable it if you have
140 a platform that can toggle the RF-Kill GPIO.
142 config ATH9K_CHANNEL_CONTEXT
143 bool "Channel Context support"
147 This option enables channel context support in ath9k, which is needed
148 for multi-channel concurrency. Enable this if P2P PowerSave support
152 bool "Atheros ath9k support for PC OEM cards" if EXPERT
156 config ATH9K_PCI_NO_EEPROM
157 tristate "Atheros ath9k pci loader for EEPROM-less chips"
161 This separate driver provides a loader in order to support the
162 AR500X to AR92XX-generation of ath9k PCI(e) WiFi chips, which have
163 their initialization data (which contains the real PCI Device ID
164 that ath9k will need) stored together with the calibration data out
165 of reach for the ath9k chip.
167 These devices are usually various network appliances, routers or
168 access Points and such.
173 tristate "Atheros HTC based wireless cards support"
174 depends on USB && MAC80211
175 select MAC80211_LEDS if LEDS_CLASS=y || LEDS_CLASS=MAC80211
179 Support for Atheros HTC based cards.
180 Chipsets supported: AR9271
182 For more information:
183 https://wireless.wiki.kernel.org/en/users/Drivers/ath9k_htc
185 The built module will be ath9k_htc.
187 config ATH9K_HTC_DEBUGFS
188 bool "Atheros ath9k_htc debugging"
189 depends on ATH9K_HTC && DEBUG_FS
190 select ATH9K_COMMON_DEBUG
192 Say Y, if you need access to ath9k_htc's statistics.
193 As well as access to the FFT/spectral data.
196 bool "Random number generator support"
197 depends on ATH9K && (HW_RANDOM = y || HW_RANDOM = ATH9K)
200 This option incorporates the ADC register output as a source of
201 randomness into Linux entropy pool (/dev/urandom and /dev/random)
203 Say Y, feeds the entropy directly from the WiFi driver to the input
206 config ATH9K_COMMON_SPECTRAL
207 bool "Atheros ath9k/ath9k_htc spectral scan support"
208 depends on ATH9K_DEBUGFS || ATH9K_HTC_DEBUGFS
212 Say Y to enable access to the FFT/spectral data via debugfs.
