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