2025-02-21wifi: rtw89: rtw8852b{t}: fix TSSI debug timestampsDmitry Antipov
Since the vendor driver is claimed to measure 'tssi_alimk_time' of 'struct rtw89_tssi_info' in microseconds, adjust rtw8852b{t}-specific '_tssi_alimentk()' to not mess the former with nanoseconds and print both per-call and accumulated times. Compile tested only.

2024-08-27wifi: rtw89: 8852bx: use right chanctx whenever possible in RFK flowZong-Zhe Yang
No longer access chan with hard-code RTW89_CHANCTX_X whenever possible. Instead, obtain the right chanctx from somewhere and use it in RTL8852BX RFK (RF calibration) related code.

2024-08-02wifi: rtw89: pass chanctx_idx to rtw89_btc_{path_}phymap()Zong-Zhe Yang
Originally, rtw89_btc_phymap() and rtw89_btc_path_phymap() access chan with hard-code RTW89_CHANCTX_0. But, they are problematic when the chip supports multiple channels. So, change their prototype and pass chanctx_idx ahead. Let callers still pass RTW89_CHANCTX_0 for now, but we will refine callers in the following.

2024-08-02wifi: rtw89: rename sub_entity to chanctxZong-Zhe Yang
Originally, we planed to fill MAC_0/1 indicators with chanctx and use sub_entity_xxx for these things. However, there are some reasons listed below which make us give up this plan after we know our Wi-Fi 7 HW design. 1. one link is bound to one HW band during its life time but, one link might change chanctx dynamically 2. in concurrent mode, assume 1st vif is MLD 1st vif's 2nd link might use the same chanctx as 2nd vif but, they are not on the same HW band So, we let sub_entity_xxx stuffs deal with only chanctx now. And, to be more readable, we rename sub_entity related words to chanctx. No logic is changed.

New upcoming chip is RTL8852BE-VT (or RTL8852BTE; 8852BT PCIE interface), which is a variant of 8852B, and many codes excepting to RF calibration can be shared, so move common code to an new kernel module named rtw89_8852b_common.ko.

DPK is short for digital pre-distortion calibration. It can adjusts digital waveform according to PA linear characteristics dynamically to enhance TX EVM. Do this calibration when we are going to run on AP channel. To prevent power offset out of boundary, it monitors thermal and set proper boundary to register.

2022-10-19wifi: rtw89: 8852b: rfk: add TSSIPing-Ke Shih
TSSI is transmitter signal strength indication, which is a close-loop hardware circuit to feedback actual transmitting power as a reference for next transmission. When we setup channel to connect an AP, it does full calibration. When switching bands or channels, it needs to reset hardware status to prevent use wrong feedback of previous transmission. To do TX power compensation reflecting current temperature, it loads tables of compensation values into registers according to channel and band group.

2022-10-19wifi: rtw89: 8852b: rfk: add IQKPing-Ke Shih
IQ signal calibration is a very important calibration to yield good RF performance. We do this calibration only if we are going to run on AP channel. During scanning phase, without this calibration RF performance is still acceptable because it transmits with low data rate at this phase.

set_channel is main function to configure channel and bandwidth for all layers, namely MAC, BB and RF. Additionally, MAC layer enables CCK rate checking to avoid wrong rate from driver. BB layer configures SCO (Sample Clock Offset) for CCK, TX gain error/offset, and reset baseband hardware circuit after all configurations done.
