It includes patch 1/4 to correct start time of NoA, and patch 2/4 is to treat remain-on-channel and hardware scan, which are also to set/switch channels. To prevent interference, stop firmware MCC switching when driver receive these two kinds of request. Then, we declare 8852c can support two channel context, and update interface combination to support MCC of STA + P2P. <<< 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. [DONE] disable some dynamic tracking mechanism of RF calibration when MCC is running. Group 7. [DONE] monitor states and adjust timeslot patterns. For example, if BT device leaves, we can reassign the slot to WiFi. Group 8. [CURRNET] Remain-on-channel and hardware scan are related to channel context, so need some treatments to work with MCC properly. Group 9. [CURRENT] Finally, we declare 8852C to support MCC Zong-Zhe Yang (4): wifi: rtw89: mcc: fix NoA start time when GO is auxiliary wifi: rtw89: pause/proceed MCC for ROC and HW scan wifi: rtw89: 8852c: declare to support two chanctx wifi: rtw89: declare MCC in interface combination drivers/net/wireless/realtek/rtw89/chan.c | 74 +++++++++++++++++++ drivers/net/wireless/realtek/rtw89/chan.h | 8 ++ drivers/net/wireless/realtek/rtw89/core.c | 29 +++++++- drivers/net/wireless/realtek/rtw89/core.h | 1 + drivers/net/wireless/realtek/rtw89/fw.c | 4 +- drivers/net/wireless/realtek/rtw89/rtw8852c.c | 2 +- 6 files changed, 113 insertions(+), 5 deletions(-)
