wifi: ath11k: Add multi TX ring support for WCN6750

2022-09-10T06:27:54Z

Currently in the case of WCN6750, only one TCL ring is used for TX, this is limiting the TX throughput in 160 MHz case, enabling multiple TCL rings on WCN6750 has shown an improvement of nearly 300 Mbps in the case of TCP TX, therefore add the support of multi TX ring for WCN6750. Currently TCL ring is selected based on CPU ID, this logic cannot be applied for WCN6750 as there is chance of out of order TX of packets and to avoid this, choose TCL ring based on flow hash so that packets of the same flow will end up on same TCL ring. For the same reason, TCL ring retry logic is also not applicable for WCN6750. Also the mapping of TCL, WBM & RBM IDs for WCN6750 is different from existing devices. Create a new TCM/WBM/RBM mapping for WCN6750. Change does not impact existing ath11k devices.

ath11k: add data path support for QCN9074

2021-02-17T09:32:51Z

hal rx descriptor is different for QCN9074 target type. since rx_msdu_end, rx_msdu_start, rx_mpdu_start elements are in different placement/alignment. In order to have generic data path, introduce platform specific hal rx descriptor access ops in ath11k_hw_ops.

ath11k: add hal support for QCN9074

2021-02-17T09:32:48Z

Define the hal ring address and ring meta descriptor mask for QCN9074. Move the platform specific address to the ath11k_hw_regs. Define tx_mesh_enable ops in ath11k_hw_ops since its accessing platform specific TCL descriptor.

ath11k: Update tx descriptor search index properly

2021-02-09T07:22:52Z

Tx descriptor search index field should be updated with hw peer id and not by AST Hash as per the HW/FW recommendation. Incorrect search index causes throughput degradation in all scenario for all the platforms. so updated the search index field with hw peer id, which is a common change applicable for all the platforms. Also no need of these configuration for non station type. seen 10% throughput increase in WDS traffic with this change.

ath11k: hal: create hw_srng_config dynamically

2020-08-17T10:18:38Z

On QCA6390 reg_start and reg_size values are different from IPQ8074 so we need to change the values runtime. As we can't modify a static const variable hw_srng_config directly, instead use it as a template, copy it and modify the copy with correct values.

ath11k: optimize ath11k_hal_tx_status_parse

ath11k: optimise ath11k_dp_tx_completion_handler

2019-12-18T17:39:59Z

the current code does 4 memcpys for each completion frame. 1) duplicate the desc 2 + 3) inside kfifo insertion 4) kfifo remove The code simply drops the kfifo and uses a trivial ring buffer. This requires a single memcpy for insertion. There is no removal needed as we can simply use the inserted data for processing. As the code runs inside the NAPI context it is atomic and there is no need for most of the locking. Signed-off-by: John Crispin Signed-off-by: Kalle Valo
