It includes group 6/7 patches below that aims to adjust RFK (RF calibrations) behavior to fit MCC situation and add a track work to monitor states including MAC ID bitmap of connected stations, beacon offset, P2P PS, and BT timeslot. <<< Below commit message is kept as first patchset for reference >>> TDMA-based MCC (STA+P2P) is a kind of multiple interfaces concurrence. Basically, driver is to calculate timeslot pattern and firmware follows the pattern to switch channels. Since BT-coexistence is also a TDMA-based mechanism, also consider BT timeslot into pattern if BT devices present. To easier to review these 20+ patches, I summary basic purpose of these patches below by group, and submit them by small patchset one by one. Group 1. [DONE] get BT timeslot from coex mechanism Group 2. [DONE] adjust some stuff related to driver channel context Group 3. [DONE] P2P NoA infrastructure to add the IE to beacon when playing GO Group 4. [DONE] adjust driver to support 2 channel context Group 5. [DONE] calculate timeslot patterns and trigger firmware to switch channels followed the patterns Group 6. [CURRENT] disable some dynamic tracking mechanism of RF calibration when MCC is running. Group 7. [CURRENT] monitor states and adjust timeslot patterns. For example, if BT device leaves, we can reassign the slot to WiFi. Group 8. Remain-on-channel and hardware scan are related to channel context, so need some treatments to work with MCC properly. Group 9. Finally, we declare 8852C to support MCC Zong-Zhe Yang (8): wifi: rtw89: 52c: rfk: refine MCC channel info notification wifi: rtw89: rfk: disable driver tracking during MCC wifi: rtw89: 52c: rfk: disable DPK during MCC wifi: rtw89: mcc: update role bitmap when changed wifi: rtw89: mcc: track beacon offset and update when needed wifi: rtw89: mcc: deal with P2P PS change wifi: rtw89: mcc: deal with BT slot change wifi: rtw89: mcc: deal with beacon NoA if GO exists drivers/net/wireless/realtek/rtw89/chan.c | 336 +++++++++++++++++- drivers/net/wireless/realtek/rtw89/chan.h | 6 + drivers/net/wireless/realtek/rtw89/core.c | 29 +- drivers/net/wireless/realtek/rtw89/core.h | 15 + drivers/net/wireless/realtek/rtw89/fw.c | 7 +- drivers/net/wireless/realtek/rtw89/fw.h | 5 + drivers/net/wireless/realtek/rtw89/mac.c | 1 + drivers/net/wireless/realtek/rtw89/mac80211.c | 3 +- drivers/net/wireless/realtek/rtw89/rtw8852c.c | 7 + .../net/wireless/realtek/rtw89/rtw8852c_rfk.c | 84 ++++- .../net/wireless/realtek/rtw89/rtw8852c_rfk.h | 3 + 11 files changed, 477 insertions(+), 19 deletions(-)
