For WiFi 7 chips, some fields and predefined length are changed, so add them accordingly. The mac_id field is used to identify peer that send a packet, and we can use it to know RSSI and traffic from the peer. For WiFi 7 chips, RXWD.mac_id of PPDU status packet is not set by hardware.

2023-10-30wifi: rtw89: pci: add new RX ring design to determine full RX ring efficientlyPing-Ke Shih
To make hardware efficient to determine if RX ring is full, introduce new design that checks if reading and writing indices are equal. Comparing to old design, initial indices of both reading and writing indices are 0 that means empty, and hardware checks full by "writing index + 1 == reading index". The "+1" has extra cost for hardware, so new design is to avoid this. Take ring size is 256 as an example, the initial reading and writing indices are 255 and 0 respectively; the initial values mean empty. If two indices are the same, for example 5 and 5, it means ring is full. wp rp used_cnt state 255 0 0 initial (ring is empty) 255 1 1 receive 1st packet 255 2 2 receive 2nd packet 0 2 1 driver read 1st packet 1 2 0 driver read 2nd packet (ring is empty) : 5 5 255 ring is full Note: 'rp' is hardware writing index Signed-off-by: Ping-Ke Shih <pkshih@realtek.com> Signed-off-by: Kalle Valo <kvalo@kernel.org> Link: https://lore.kernel.org/r/20231026120049.9187-4-pkshih@realtek.com

PCI rings are used to DMA TX/RX packets. The address of WiFi 7 chips are different from previous ones, so add them according to hardware design. Another difference is that driver doesn't need to configure BD (buffer descriptor) RAM table, which is used by hardware to fetch BD ahead before fetching whole TX data. A TX ring contains numbers of TX BD (e.g. 512): TX BD (buffer descriptor; continual memory) +---+---+---+---+ +---+ | | | | | ... | | +-|-+---+---+---+ +---+ | | point to TX WD (WiFi descriptor; metadata of a skb data) v +------+ | | | | +-|----+ | | point to a skb data v +------+ | | | | +------+ Signed-off-by: Ping-Ke Shih <pkshih@realtek.com> Signed-off-by: Kalle Valo <kvalo@kernel.org> Link: https://lore.kernel.org/r/20231026120049.9187-3-pkshih@realtek.com

2023-10-12wifi: rtw89: parse EHT information from RX descriptor and PPDU status packetPing-Ke Shih
There are two kinds of RX packets -- normal and its PPDU status packet. Both have RX descriptor containing some information such as rate, GI and bandwidth, and we use these information to find the relationship between two kinds of packets. Then, we can get more information like RSSI and EVM from PPDU status packet.
