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