This is useful to help test world roaming 77 * and the driver regulatory_hint() call and combinations of these. 78 * If you want to do specific alpha2 regulatory domain tests simply 79 * use the userspace regulatory request as that will be respected as 80 * well without the need of this module parameter. This is designed 81 * only for testing the driver regulatory request, world roaming 82 * and all possible combinations. 83 * 84 * @HWSIM_REGTEST_DISABLED: No regulatory tests are performed, 85 * this is the default value. 86 * @HWSIM_REGTEST_DRIVER_REG_FOLLOW: Used for testing the driver regulatory 87 * hint, only one driver regulatory hint will be sent as such the 88 * secondary radios are expected to follow. 89 * @HWSIM_REGTEST_DRIVER_REG_ALL: Used for testing the driver regulatory 90 * request with all radios reporting the same regulatory domain. 91 * @HWSIM_REGTEST_DIFF_COUNTRY: Used for testing the drivers calling 92 * different regulatory domains requests. Expected behaviour is for 93 * an intersection to occur but each device will still use their 94 * respective regulatory requested domains. Subsequent radios will 95 * use the resulting intersection. 96 * @HWSIM_REGTEST_WORLD_ROAM: Used for testing the world roaming. We accomplish 97 * this by using a custom beacon-capable regulatory domain for the first 98 * radio. All other device world roam. 99 * @HWSIM_REGTEST_CUSTOM_WORLD: Used for testing the custom world regulatory 100 * domain requests. All radios will adhere to this custom world regulatory 101 * domain. 102 * @HWSIM_REGTEST_CUSTOM_WORLD_2: Used for testing 2 custom world regulatory 103 * domain requests. The first radio will adhere to the first custom world 104 * regulatory domain, the second one to the second custom world regulatory 105 * domain. All other devices will world roam. 106 * @HWSIM_REGTEST_STRICT_FOLLOW: Used for testing strict regulatory domain 107 * settings, only the first radio will send a regulatory domain request 108 * and use strict settings. The rest of the radios are expected to follow. 109 * @HWSIM_REGTEST_STRICT_ALL: Used for testing strict regulatory domain 110 * settings. All radios will adhere to this. 111 * @HWSIM_REGTEST_STRICT_AND_DRIVER_REG: Used for testing strict regulatory 112 * domain settings, combined with secondary driver regulatory domain 113 * settings. The first radio will get a strict regulatory domain setting 114 * using the first driver regulatory request and the second radio will use 115 * non-strict settings using the second driver regulatory request. All 116 * other devices should follow the intersection created between the 117 * first two. 118 * @HWSIM_REGTEST_ALL: Used for testing every possible mix. You will need 119 * at least 6 radios for a complete test. We will test in this order: 120 * 1 - driver custom world regulatory domain 121 * 2 - second custom world regulatory domain 122 * 3 - first driver regulatory domain request 123 * 4 - second driver regulatory domain request 124 * 5 - strict regulatory domain settings using the third driver regulatory 125 * domain request 126 * 6 and on - should follow the intersection of the 3rd, 4rth and 5th radio 127 * regulatory requests. 128 */ 129 enum hwsim_regtest { 130 HWSIM_REGTEST_DISABLED = 0, 131 HWSIM_REGTEST_DRIVER_REG_FOLLOW = 1, 132 HWSIM_REGTEST_DRIVER_REG_ALL = 2, 133 HWSIM_REGTEST_DIFF_COUNTRY = 3, 134 HWSIM_REGTEST_WORLD_ROAM = 4, 135 HWSIM_REGTEST_CUSTOM_WORLD = 5, 136 HWSIM_REGTEST_CUSTOM_WORLD_2 = 6, 137 HWSIM_REGTEST_STRICT_FOLLOW = 7, 138 HWSIM_REGTEST_STRICT_ALL = 8, 139 HWSIM_REGTEST_STRICT_AND_DRIVER_REG = 9, 140 HWSIM_REGTEST_ALL = 10, 141 };
