9 config ATH9K_DFS_DEBUGFS
11 depends on ATH9K_DEBUGFS && ATH9K_DFS_CERTIFIED
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
30 This module adds support for wireless adapters based on
31 Atheros IEEE 802.11n AR5008, AR9001 and AR9002 family
32 of chipsets. For a specific list of supported external
33 cards, laptops that already ship with these cards and
34 APs that come with these cards refer to ath9k wiki
37 http://wireless.kernel.org/en/users/Drivers/ath9k/products
39 If you choose to build a module, it'll be called ath9k.
42 bool "Atheros ath9k PCI/PCIe bus support"
44 depends on ATH9K && PCI
46 This option enables the PCI bus support in ath9k.
48 Say Y, if you have a compatible PCI/PCIe wireless card.
51 bool "Atheros ath9k AHB bus support"
55 This option enables the AHB bus support in ath9k.
57 Say Y, if you have a SoC with a compatible built-in
58 wireless MAC. Say N if unsure.
61 bool "Atheros ath9k debugging"
62 depends on ATH9K && DEBUG_FS
63 select MAC80211_DEBUGFS
64 select ATH9K_COMMON_DEBUG
66 Say Y, if you need access to ath9k's statistics for
67 interrupts, rate control, etc.
69 Also required for changing debug message flags at run time and for
72 config ATH9K_STATION_STATISTICS
73 bool "Detailed station statistics"
74 depends on ATH9K && ATH9K_DEBUGFS && DEBUG_FS
75 select MAC80211_DEBUGFS
78 This option enables detailed statistics for association stations.
81 bool "Atheros ath9k TX99 testing support"
82 depends on ATH9K_DEBUGFS && CFG80211_CERTIFICATION_ONUS
85 Say N. This should only be enabled on systems undergoing
86 certification testing and evaluation in a controlled environment.
87 Enabling this will only enable TX99 support, all other modes of
88 operation will be disabled.
90 TX99 support enables Specific Absorption Rate (SAR) testing.
91 SAR is the unit of measurement for the amount of radio frequency(RF)
92 absorbed by the body when using a wireless device. The RF exposure
93 limits used are expressed in the terms of SAR, which is a measure
94 of the electric and magnetic field strength and power density for
95 transmitters operating at frequencies from 300 kHz to 100 GHz.
96 Regulatory bodies around the world require that wireless device
97 be evaluated to meet the RF exposure limits set forth in the
98 governmental SAR regulations.
100 config ATH9K_DFS_CERTIFIED
101 bool "Atheros DFS support for certified platforms"
102 depends on ATH9K && CFG80211_CERTIFICATION_ONUS
105 This option enables DFS support for initiating radiation on
106 ath9k. There is no way to dynamically detect if a card was DFS
107 certified and as such this is left as a build time option. This
108 option should only be enabled by system integrators that can
109 guarantee that all the platforms that their kernel will run on
110 have obtained appropriate regulatory body certification for a
111 respective Atheros card by using ath9k on the target shipping
114 This is currently only a placeholder for future DFS support,
115 as DFS support requires more components that still need to be
116 developed. At this point enabling this option won't do anything
117 except increase code size.
120 bool "Atheros ath9k ACK timeout estimation algorithm"
124 This option enables ath9k dynamic ACK timeout estimation algorithm
125 based on ACK frame RX timestamp, TX frame timestamp and frame
129 bool "Wake on Wireless LAN support (EXPERIMENTAL)"
130 depends on ATH9K && PM
133 This option enables Wake on Wireless LAN support for certain cards.
134 Currently, AR9462 is supported.
137 bool "Atheros ath9k rfkill support" if EXPERT
139 depends on RFKILL=y || RFKILL=ATH9K
142 Say Y to have ath9k poll the RF-Kill GPIO every couple of
143 seconds. Turn off to save power, but enable it if you have
144 a platform that can toggle the RF-Kill GPIO.
146 config ATH9K_CHANNEL_CONTEXT
147 bool "Channel Context support"
151 This option enables channel context support in ath9k, which is needed
152 for multi-channel concurrency. Enable this if P2P PowerSave support
156 bool "Atheros ath9k support for PC OEM cards" if EXPERT
160 config ATH9K_PCI_NO_EEPROM
161 tristate "Atheros ath9k pci loader for EEPROM-less chips"
165 This separate driver provides a loader in order to support the
166 AR500X to AR92XX-generation of ath9k PCI(e) WiFi chips, which have
167 their initialization data (which contains the real PCI Device ID
168 that ath9k will need) stored together with the calibration data out
169 of reach for the ath9k chip.
171 These devices are usually various network appliances, routers or
172 access Points and such.
177 tristate "Atheros HTC based wireless cards support"
178 depends on USB && MAC80211
185 Support for Atheros HTC based cards.
186 Chipsets supported: AR9271
188 For more information: http://wireless.kernel.org/en/users/Drivers/ath9k_htc
190 The built module will be ath9k_htc.
192 config ATH9K_HTC_DEBUGFS
193 bool "Atheros ath9k_htc debugging"
194 depends on ATH9K_HTC && DEBUG_FS
195 select ATH9K_COMMON_DEBUG
197 Say Y, if you need access to ath9k_htc's statistics.
198 As well as access to the FFT/spectral data.
201 bool "Random number generator support"
202 depends on ATH9K && (HW_RANDOM = y || HW_RANDOM = ATH9K)
205 This option incorporates the ADC register output as a source of
206 randomness into Linux entropy pool (/dev/urandom and /dev/random)
208 Say Y, feeds the entropy directly from the WiFi driver to the input
211 config ATH9K_COMMON_SPECTRAL
212 bool "Atheros ath9k/ath9k_htc spectral scan support"
213 depends on ATH9K_DEBUGFS || ATH9K_HTC_DEBUGFS
217 Say Y to enable access to the FFT/spectral data via debugfs.
