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