To debug channel concurrency more centrally, we add a new debug flag, RTW89_DBG_CHAN, for channel related things, especially channel concurrency. Then, we change MCC (multi-channel concurrency) C2H (chip to host packets) debug flag to it. Besides, refine debug logs to show TSF in u64 directly. Signed-off-by:

RXI300 is a HW design to maintain stuffs across BUS, e.g. AXI, AHB, APB. It will feedback an error when host does an invalid BUS operation. For example, * BUS master request without power/clock on. * host reads/writes/accesses an invalid address. They might lead to problems such as BUS timeout, platform hang, etc. So, once if RXI300 feedback an error, it notifies that driver need a L2 SER (system error recovery) to reset things. Previously, driver did not parse the error scenario for RXI300. We add it and assign a corresponding error code which will make SER flow do L2 reset. Signed-off-by:

Only 8852C chip has valid pages on RTW89_DBG_SEL_MAC_30. To other chips, this section is an address hole. It will lead to crash if trying to access this section on chips except for 8852C. So, we avoid that. Signed-off-by:

Originally, rtw89_mac_port_tsf_sync() contains randomization logic internally. However, not all situation, we need the randomization. So, split out the generic part from it. And, make the full logic of original one contained in rtw89_mac_port_tsf_sync_rand(). It will still be used by its original caller as before. Then, the generic one will be used in MCC (multi-channel concurrency) management flow. MCC will implement its logic to decide the offset for TSF sync. Signed-off-by:

Strictly speaking, the unit of the offset should be TU instead of ms. So, correct it and the macro for calculation. Then, to make the macro generic, the factor n is moved outside. Signed-off-by:

The origin code will enable TDMA WL:BT = 50:50 to prevent Wi-Fi throughput suddenly drop to 0 in the moment while A2DP pause. And this protection just a short moment, and will turn to Bluetooth idle case when A2DP turn into sniff mode. But the raspberryPI simulated A2DP device will not turn into sniff mode. So the protection will bring the throughput drop. Signed-off-by:

The Marvell SD8978 (aka NXP IW416) uses identical registers as SD8987, so reuse the existing mwifiex_reg_sd8987 definition. Note that mwifiex_reg_sd8977 and mwifiex_reg_sd8997 are likewise identical, save for the fw_dump_ctrl register: They define it as 0xf0 whereas mwifiex_reg_sd8987 defines it as 0xf9. I've verified that 0xf9 is the correct value on SD8978. NXP's out-of-tree driver uses 0xf9 for all of them, so there's a chance that 0xf0 is not correct in the mwifiex_reg_sd8977 and mwifiex_reg_sd8997 definitions. I cannot test that for lack of hardware, hence am leaving it as is. NXP has only released a firmware which runs Bluetooth over UART. Perhaps Bluetooth over SDIO is unsupported by this chipset. Consequently, only an "sdiouart" firmware image is referenced, not an alternative "sdsd" image. Signed-off-by:

This chip is present on at least these Apple T2 Macs: * hawaii: MacBook Air 13" (Late 2018) * hawaii: MacBook Air 13" (True Tone, 2019) Users report seeing PCI revision ID 12 for this chip, which Arend reports should be revision C2, but Apple has the firmware tagged as revision C1. Assume the right cutoff point for firmware versions is revision ID 11 then, and leave older revisions using the non-versioned firmware filename (Apple only uses C1 firmware builds). Reviewed-by:

The commit that introduced support for this chip incorrectly claimed it is a Cypress-specific part, while in actuality it is just a variant of BCM4355 silicon (as evidenced by the chip ID). The relationship between Cypress products and Broadcom products isn't entirely clear but given what little information is available and prior art in the driver, it seems the convention should be that originally Broadcom parts should retain the Broadcom name. Thus, rename the relevant constants and firmware file. Also rename the specific 89459 PCIe ID to BCM43596, which seems to be the original subvariant name for this PCI ID (as defined in the out-of-tree bcmdhd driver). Since Cypress added this part and will presumably be providing its supported firmware, we keep the CYW designation for this device. We also drop the RAW device ID in this commit. We don't do this for the other chips since apparently some devices with them exist in the wild, but there is already a 4355 entry with the Broadcom subvendor and WCC firmware vendor, so adding a generic fallback to Cypress seems redundant (no reason why a device would have the raw device ID *and* an explicitly programmed subvendor).

Add compatibility with WPS by passing on WPS enrollee information in probe requests. Ignore other IEs supplied in the scan request. This also has the added benefit of restoring compatibility with newer wpa_supplicant versions that always add scan IEs. Previously, with max_scan_ie_len set to 0, scans would always fail.

Add a define for the TLV type that will be used to add WPS enrollee information to probe requests. Suggested-by:

Doug Brown authored
The existing code only converts the first IE to a TLV, but it returns a value that takes the length of all IEs into account. When there is more than one IE (which happens with modern wpa_supplicant versions for example), the returned length is too long and extra junk TLVs get sent to the firmware, resulting in an association failure. Fix this by finding the first RSN or WPA IE and only adding that. This has the extra benefit of working properly if the RSN/WPA IE isn't the first one in the IE buffer. While we're at it, clean up the code to use the available structs like the other lbs_add_* functions instead of directly manipulating the TLV buffer. Signed-off-by:
