To support multi link operation, we need to combine all the link/pdev under a single wiphy. This avoids the overhead of synchronization across multiple hardware instances in both the cfg80211 and mac80211 layers. Currently, each link/pdev is registered as separate wiphy, tightly coupled with link/pdev/radio (ar) structure. To enable single wiphy registration within the chip, we decouple the wiphy data entity from the link/pdev/radio (ar) structure and move it under the chip (ab) structure with a new data container (ath12k_hw) structure. This approach improves scalability for future multi link operation support. mac80211 hw private data structure diagram ------------------------------------------ Now After +---------------------+ +---------------------+ |mac80211 hw priv data| |mac80211 hw priv data| | | | | | | | | | | | | | | | ath12k_hw (ah) | | | | | | | +-------------------> | | | ath12k (ar) | | +-------------+ | | | | | | | | | | | ath12k (ar) | | | | | | | | | | | | | | | | | +-------------+ | | | | | | | | | +---------------------+ +---------------------+ Tested-on: QCN9274 hw2.0 PCI WLAN.WBE.1.0.1-00029-QCAHKSWPL_SILICONZ-1 Tested-on: WCN7850 hw2.0 PCI WLAN.HMT.1.0.c5-00481-QCAHMTSWPL_V1.0_V2.0_SILICONZ-3 Signed-off-by: Karthikeyan Periyasamy <quic_periyasa@quicinc.com> Signed-off-by: Kalle Valo <quic_kvalo@quicinc.com> Link: https://msgid.link/20240118010320.3918136-3-quic_periyasa@quicinc.com
