Driver sets the related PNO configuration to firmware before entering WoW and firmware then scans periodically and wakes up host if a specific SSID is found. Note that firmware crashes if we enable it for both P2P vdev and station vdev simultaneously because firmware can only support one vdev at a time. Since there is rare scenario for a P2P vdev to do net-detect, skip it for P2P vdevs. Tested-on: WCN7850 hw2.0 PCI WLAN.HMT.1.0-03427-QCAHMTSWPL_V1.0_V2.0_SILICONZ-1.15378.4 Signed-off-by: Baochen Qiang Acked-by: Jeff Johnson --- drivers/net/wireless/ath/ath12k/core.h | 2 + drivers/net/wireless/ath/ath12k/mac.c | 12 ++ drivers/net/wireless/ath/ath12k/wmi.c | 144 ++++++++++++++++++ drivers/net/wireless/ath/ath12k/wmi.h | 169 +++++++++++++++++++++ drivers/net/wireless/ath/ath12k/wow.c | 199 ++++++++++++++++++++++++- 5 files changed, 523 insertions(+), 3 deletions(-) diff --git a/drivers/net/wireless/ath/ath12k/core.h b/drivers/net/wireless/ath/ath12k/core.h index 40b4f9b4d570..af5c489b9fd2 100644 --- a/drivers/net/wireless/ath/ath12k/core.h +++ b/drivers/net/wireless/ath/ath12k/core.h @@ -628,6 +628,8 @@ struct ath12k { u32 freq_low;
