wifi: ath11k: fix IOMMU errors on buffer rings

2024-01-11T11:18:49Z

virt_to_phys() doesn't work on systems with IOMMU enabled, which have non-identity physical-to-IOVA mappings. It leads to IO_PAGE_FAULTs like this: [IO_PAGE_FAULT domain=0x0023 address=0x1cce00000 flags=0x0020] And no association to the AP can be established. This patch changes that to dma_map_single(), which works correctly. Even virt_to_phys() documentation says device drivers should not use it: This function does not give bus mappings for DMA transfers. In almost all conceivable cases a device driver should not be using this function Tested-on: QCN9074 hw1.0 PCI WLAN.HK.2.7.0.1-01744-QCAHKSWPL_SILICONZ-1 Signed-off-by: Zhenghao Gu Acked-by: Jeff Johnson Signed-off-by: Kalle Valo Link: https://msgid.link/20231212031914.47339-1-imguzh@gmail.com

Now that the previous patch changed ath11k_dbg() to print the debug level there's no need to have the level in the actual message anymore. So remove those.

wifi: ath11k: remap ce register space for IPQ5018

2022-12-07T17:16:53Z

In IPQ5018 ce register space is moved out of wcss unlike ipq8074 or ipq6018 and the space is not contiguous, hence remap the CE registers to a new space to access them. Register read/write is modified to check if the register to be written falls in the CE register space and corresponding register is written. Also adjust the interrupt register address to ce irq enable/disable.

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.
