12 dayswifi: iwlwifi: mvm/fw: Avoid -Wflex-array-member-not-at-end warningsGustavo A. R. Silva
-Wflex-array-member-not-at-end was introduced in GCC-14, and we are getting ready to enable it, globally. We have a flexible struct iwl_tx_cmd_v6 in the middle of a few structs, but those don't even need the flexible part. So, we add iwl_tx_cmd_v6_params, that will contain everything except the flexible array and use this one for the containing structs. Also, as part of the refactoring remove unused flex array `payload`. So, with these changes, fix the following warnings: drivers/net/wireless/intel/iwlwifi/mld/../fw/api/tdls.h:134:27: warning: structure containing a flexible array member is not at the end of another structure [-Wflex-array-member-not-at-end] drivers/net/wireless/intel/iwlwifi/mld/../fw/api/tdls.h:53:27: warning: structure containing a flexible array member is not at the end of another structure [-Wflex-array-member-not-at-end] drivers/net/wireless/intel/iwlwifi/mld/../fw/api/tx.h:745:27: warning: structure containing a flexible array member is not at the end of another structure [-Wflex-array-member-not-at-end] drivers/net/wireless/intel/iwlwifi/mld/../fw/api/tx.h:764:27: warning: structure containing a flexible array member is not at the end of another structure [-Wflex-array-member-not-at-end] drivers/net/wireless/intel/iwlwifi/mvm/../fw/api/tdls.h:134:27: warning: structure containing a flexible array member is not at the end of another structure [-Wflex-array-member-not-at-end] drivers/net/wireless/intel/iwlwifi/mvm/../fw/api/tdls.h:53:27: warning: structure containing a flexible array member is not at the end of another structure [-Wflex-array-member-not-at-end] drivers/net/wireless/intel/iwlwifi/mvm/../fw/api/tx.h:745:27: warning: structure containing a flexible array member is not at the end of another structure [-Wflex-array-member-not-at-end] drivers/net/wireless/intel/iwlwifi/mvm/../fw/api/tx.h:764:27: warning: structure containing a flexible array member is not at the end of another structure [-Wflex-array-member-not-at-end] Signed-off-by: Gustavo A.

2025-07-09wifi: iwlwifi: match discrete/integrated to fix some namesJohannes Berg
Some device names were wrong because our internal data suggested that discrete Ga devices have B-step RF, when they actually have C-step. However, matching the step for them is bad anyway. Change the code to be able to find the devinfo depending on the device being integrated or discrete. This is only for the names, since the RF config cannot be different for the same RF because it's discrete or integrated, so add a kunit test that ensures both (a) the RF config is the same and (b) the name is different (the latter really only because that's the whole point of having a match on the discrete/integrated bit.) Remove the RF step matching since it's no longer needed now.

2025-05-15wifi: iwlwifi: rename ctx-info-gen3 to ctx-info-v2Miri Korenblit
Context info was introduced in 22000, and was significantly changed in ax210. The new version of context info was called 'gen3', probably because in 22000, the gen2 transport was added. But this name is just wrong: - if 'gen' enumerates transports, there was not a gen3 transport, just a few modifications to gen1/2 transports needed for ax210. - if 'gen' enumerates devices, then we can just use the device names. Also, context info will soon become a lib, agnostic of the transport generations. Simply replace 'gen3' with 'v2'.

We have iwl_tx_cmd for devices older than 22000, iwl_tx_cmd_gen2 for 22000 devices, and iwl_tx_cmd_gen3 ax210 and up. But the convention for all other APIs is to have the latest version without any prefix and the older ones - with a _vX prefix, where X is the highest version that this struct support. The term 'gen' was introduced as the name of the (back then) new transport, and should not be used as a device name (for that we have the actual names: 22000, ax210, etc.) Now as a new transport, called 'gen3', is going to be written and it can be confused with this API.

2025-05-13wifi: iwlwifi: cfg: reduce configuration struct sizeJohannes Berg
We don't need the CORES() match nor jacket (which really doesn't even make sense to match to the RF anyway), and since the subdevice masks we care about are contiguous, we can encode them as highest and lowest bit set (automatically.) By encoding whether to match or not as separate flags and taking advantage of the limited range of the RF type, step and ID we can reduce the amount of memory needed for the table, while also making the logic (apart perhaps from the subdevice mask) easier to understand. This reduces the size of the module by about 1.5KiB on x86-64.
