The driver uses ieee80211_iterate_active_interfaces_atomic() and ieee80211_iterate_stations_atomic() in several places and does register accesses in the iterators. This doesn't cope with upcoming USB support as registers can only be accessed non-atomically. Split these into a two stage process: First use the atomic iterator functions to collect all active interfaces or stations on a list, then iterate over the list non-atomically and call the iterator on each entry.

coex->mutex is used in rtw_coex_info_request() only. Most callers of this function hold rtwdev->mutex already, except for one callsite in the debugfs code. The debugfs code alone doesn't justify the extra lock, so acquire rtwdev->mutex there as well and drop the now unnecessary spinlock. Signed-off-by:

Under some condition, we now have to do early request full firmware when rtw89_early_fw_feature_recognize(). In this case, we can avoid requesting full firmware twice during probing driver. So, we pass out full firmware from rtw89_early_fw_feature_recognize() if it's requested successfully. And then, if firmware is settled, we have no need to request full firmware again during normal initizating flow. Setting firmware flow is updated to be as the following. platform | early recognizing | normally initizating ----------------------------------------------------------------------- deny reading | request full FW | (no more FW requesting) partial file | | (obtain FW from early pahse) ----------------------------------------------------------------------- able to read | request partial FW | async request full FW partial file | (quite small chunk) | Signed-off-by:

Then, the outer API based on it, e.g. request_partial_firmware_into_buf(), will get the error. In the case, we cannot get the firmware stuffs right, even though there might be no error other than a permission issue on reading a partial file. So we have to request full firmware if SECURITY_LOADPIN_ENFORCE is enabled. It makes us still have a chance to do early firmware work on this kind of platforms. Signed-off-by:

The gen 2 chips RTL8192EU and RTL8188FU periodically send the driver reports about the TX rate, and the driver passes these reports to sta_statistics. The reports from RTL8192EU may or may not include the channel width. The reports from RTL8188FU do not include it. Only access the c2h->ra_report.bw field if the report (skb) is big enough. The other problem fixed here is that the code was actually never changing the channel width initially reported by rtl8xxxu_bss_info_changed because the value of RATE_INFO_BW_20 is 0.

Cypress uses the brcmfmac driver and releases firmware which will likely diverge over time (or already has). So adding support for handling that. Reviewed-by:

Arend van Spriel authored
The driver is being used by multiple vendors who develop the firmware api independently. So far the firmware api as used by the driver has not diverged (yet). This change adds framework for supporting multiple firmware apis. The vendor-specific support code has to provide a number of callback operations. Right now it is only attach and detach callbacks so no real functionality as the api is still common. This code only adds WCC variant anyway, which is selected for all devices right now. The vendor-specific part will be built in a separate module when the driver is configured to be built as a module through Kconfig, ie. when CONFIG_BRCMFMAC=m. Reviewed-by:

The CSR_HW_IF_CONFIG_REG register is no longer in use from IWL_DEVICE_FAMILY_AX210 and on. This register uses now for CSR_CTXT_INFO_BOOT_CTRL which has a different meaning and a different format. Currently we're writing to the register according to CSR_HW_IF_CONFIG_REGs format, regardless to the device family. This causes to miss-interpretation of the register value, as it is parsed according to CSR_CTXT_INFO_BOOT_CTRLs format for devices families >= IWL_DEVICE_FAMILY_AX210. Fix this by writing to the register according to the old format only for the relevant hardware. Signed-off-by:
