iwlwifi: iwl-eeprom-parse: mostly dvm only

2021-12-21T10:35:04Z

Most of iwl-eeprom-parse.c is only used for dvm but not for mvm. Hide the parts under #if IS_ENABLED(CONFIG_IWLDVM) to reduce size and code surface for mvm-only builds. Sponsored by: The FreeBSD Foundation Signed-off-by: Bjoern A. Zeeb Signed-off-by: Luca Coelho

iwlwifi: remove max_ht_ampdu_exponent config parameter

2021-02-10T23:52:10Z

This always has the same value, since we don't have any devices with different values; remove the parameter.

iwlwifi: always allow maximum A-MSDU on newer devices

2021-02-05T09:55:21Z

On devices starting from 9000 series, always allow maximum A-MSDU sizes regardless of the amsdu_size module parameter, which really hasn't meant that for a long time but just controls the receive buffer size.

iwlwifi: use SPDX tags

2020-12-09T22:15:31Z

Use SPDX tags instead of the long copyright notices. Also cleanup some duplicate copyright notices and combine the years where possible.

iwlwifi: always access the trans configuration via trans

2019-09-06T12:52:04Z

Stop accessing the trans configuration via the iwl_cfg structure and always access it via the iwl_trans structure. This completes the requirements to disassociate the trans-specific configuration from the rest of the configuration. Signed-off-by: Luca Coelho

iwlwifi: separate elements from cfg that are needed by trans_alloc

2019-09-06T12:34:25Z

In order to be able to select the cfg depending on the HW revision or on the RF ID, we need to set up the trans before selecting the cfg. To do so, move the elements from cfg that are needed by iwl_trans_alloc() to a separate struct at the top of the cfg, so it can be used by other cfg types as well, before selecting the rest of the configuration.

iwlwifi: eeprom-parse: use struct_size() in kzalloc()

2019-02-20T18:47:54Z

One of the more common cases of allocation size calculations is finding the size of a structure that has a zero-sized array at the end, along with memory for some number of elements for that array. For example: struct foo { int stuff; void *entry[]; }; instance = kzalloc(sizeof(struct foo) + sizeof(void *) * count, GFP_KERNEL); Instead of leaving these open-coded and prone to type mistakes, we can now use the new struct_size() helper: instance = kzalloc(struct_size(instance, entry, count), GFP_KERNEL); This code was detected with the help of Coccinelle.

iwlwifi: move iwl_nvm_check_version() into dvm

2018-12-14T11:04:46Z

This function is only half-used by mvm (i.e. only the nvm_version part matters, since the calibration version is irrelevant), so it's pointless to export it from iwlwifi. If mvm uses this function, it has the additional complexity of setting the calib version to a bogus value on all cfg structs. To avoid this, move the function to dvm and make a simple comparison of the nvm_version in mvm instead. Signed-off-by: Luca Coelho

iwlwifi: Add missing 11n disable module parameter check

2018-08-31T08:38:36Z

In the new method of parsing the NVM the disable_11n module parameter isn't consulted when setting up HT capabilities. Fix this. Signed-off-by: Ido Yariv Signed-off-by: Luca Coelho
