65 * enum hwsim_regtest - the type of regulatory tests we offer
67 * These are the different values you can use for the regtest
68 * module parameter. This is useful to help test world roaming
69 * and the driver regulatory_hint() call and combinations of these.
70 * If you want to do specific alpha2 regulatory domain tests simply
71 * use the userspace regulatory request as that will be respected as
72 * well without the need of this module parameter. This is designed
73 * only for testing the driver regulatory request, world roaming
74 * and all possible combinations.
76 * @HWSIM_REGTEST_DISABLED: No regulatory tests are performed,
77 * this is the default value.
78 * @HWSIM_REGTEST_DRIVER_REG_FOLLOW: Used for testing the driver regulatory
79 * hint, only one driver regulatory hint will be sent as such the
80 * secondary radios are expected to follow.
81 * @HWSIM_REGTEST_DRIVER_REG_ALL: Used for testing the driver regulatory
82 * request with all radios reporting the same regulatory domain.
83 * @HWSIM_REGTEST_DIFF_COUNTRY: Used for testing the drivers calling
84 * different regulatory domains requests. Expected behaviour is for
85 * an intersection to occur but each device will still use their
86 * respective regulatory requested domains. Subsequent radios will
87 * use the resulting intersection.
88 * @HWSIM_REGTEST_WORLD_ROAM: Used for testing the world roaming. We accomplish
89 * this by using a custom beacon-capable regulatory domain for the first
90 * radio. All other device world roam.
91 * @HWSIM_REGTEST_CUSTOM_WORLD: Used for testing the custom world regulatory
92 * domain requests. All radios will adhere to this custom world regulatory
94 * @HWSIM_REGTEST_CUSTOM_WORLD_2: Used for testing 2 custom world regulatory
95 * domain requests. The first radio will adhere to the first custom world
96 * regulatory domain, the second one to the second custom world regulatory
97 * domain. All other devices will world roam.
98 * @HWSIM_REGTEST_STRICT_FOLLOW_: Used for testing strict regulatory domain
99 * settings, only the first radio will send a regulatory domain request
100 * and use strict settings. The rest of the radios are expected to follow.
101 * @HWSIM_REGTEST_STRICT_ALL: Used for testing strict regulatory domain
102 * settings. All radios will adhere to this.
103 * @HWSIM_REGTEST_STRICT_AND_DRIVER_REG: Used for testing strict regulatory
104 * domain settings, combined with secondary driver regulatory domain
105 * settings. The first radio will get a strict regulatory domain setting
106 * using the first driver regulatory request and the second radio will use
107 * non-strict settings using the second driver regulatory request. All
108 * other devices should follow the intersection created between the
110 * @HWSIM_REGTEST_ALL: Used for testing every possible mix. You will need
111 * at least 6 radios for a complete test. We will test in this order:
112 * 1 - driver custom world regulatory domain
113 * 2 - second custom world regulatory domain
114 * 3 - first driver regulatory domain request
115 * 4 - second driver regulatory domain request
116 * 5 - strict regulatory domain settings using the third driver regulatory
118 * 6 and on - should follow the intersection of the 3rd, 4rth and 5th radio
119 * regulatory requests.
