2024-10-25wifi: rtw89: add thermal protectionPing-Ke Shih
To prevent chip overheating, reduce TX duty as the mechanism of thermal protection. When temperature is raising over a threshold, send a firmware command to reduce TX duty. If temperature is still raising, higher level is adopted to have lower active duration. The equation and unit of thermal values are different from chip to chip, so define constant thresholds of thermal value to corresponding absolute temperature of 110 and 120 degree Celsius. Latter patch will decide which thermal threshold is adopted, and current is still not enable thermal protection. For debugging, add a flag to disable_dm that thermal protection can be disabled to clarify low throughput in field.

2024-09-24wifi: rtw89: tweak driver architecture for impending MLO supportZong-Zhe Yang
The drv_priv hooked to mac80211 become as below. (drv_priv) (instance-0) +---------------+ +-----------+ +----------------+ | ieee80211_vif | <---> | rtw89_vif | -------> | rtw89_vif_link | +---------------+ +-----------+ | +----------------+ | | (instance-1) | +----------------+ +---> | rtw89_vif_link | +----------------+ (drv_priv) (instance-0) +---------------+ +-----------+ +----------------+ | ieee80211_sta | <---> | rtw89_sta | -------> | rtw89_sta_link | +---------------+ +-----------+ | +----------------+ | | (instance-1) | +----------------+ +---> | rtw89_sta_link | +----------------+ The relation bewteen mac80211 link_id and our link instance is like below. |\ (link_id) | \ 0 -------- | | 1 -------- | | ------ instance-0 (link_id: X) -> work on HW band 0 2 -------- | | ... | | ------ instance-1 (link_id: Y) -> work on HW band 1 14 -------- | | | / |/ N.B. For cases of non-MLD connection, we set our link instance-0 active with link_id 0. So, our code flow can be compatible between non-MLD connection and MLD connection. Based on above, we tweak entire driver architecture first. But, we don't dynamically enable multiple links here. That will be handled separately. Most of the things changed here are changing flows to iterate all active links and read bss_conf/link_sta data according to target link. And, for cases of scan, ROC, WOW, we use instance-0 to deal with the request. There are some things listed below, which work for now but need to extend before multiple active links. 1. tx path select suitable link instance among multiple active links 2. rx path determine rx link by PPDU instead of always link instance-0 3. CAM apply MLD pairwise key to any active links dynamically Besides, PS code cannot easily work along with tweaking architecture. With supporting MLO flag (currently false), we disable PS first and will fix it by another commit in the following.
