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