2022-04-27ath11k: Update WBM idle ring HP after FW mode onManikanta Pubbisetty
Currently, WBM idle ring HP is updated much before the shadow configuration is sent to the FW. Any update to the shadow registers before FW mode on request would not be reflected on to the actual HW registers failing to bring up the device. Send FW mode ON QMI request before WBM idle ring HP update to fix this problem.

2021-11-17ath11k: Disabling credit flow for WMI pathP Praneesh
Firmware credit flow control is enabled for WMI control services, which expects available tokens should be acquired before sending a command to the target. Also the token gets released when firmware receives the command. This credit-based flow limits driver to send WMI command only when the token available which is causing WMI commands to timeout and return -EAGAIN, whereas firmware has enough capability to process the WMI command. To fix this Tx starvation issue, introduce the ability to disable the credit flow for the WMI path. The driver sends WMI configuration for disabling credit flow to firmware by two ways. 1. By using a global flag (HTC_MSG_SETUP_COMPLETE_EX_ID msg type flags) 2. By using a local flag (ATH11K_HTC_CONN_FLAGS_DISABLE_CREDIT_FLOW_CTRL = 1 << 3) Ath11k uses both these configurations to disable credit flow for the WMI path completely. Also added a hw_param member for credit flow control by which we can enable or disable it based on per-target basis. Currently we are disabling credit flow for IPQ8074, IPQ6018, and QCN9074 as recommended by firmware.

2021-11-15ath11k: fix DMA memory free in CE pipe cleanupKarthikeyan Periyasamy
In CE pipe cleanup, DMA memory gets freed by the aligned address (base_addr_owner_space) which is wrong. It needs to be freed by the address (base_addr_owner_space_unaligned) returned by dma_alloc. So free the dma memory by the proper address. This was found in code review.

2020-12-12ath11k: implement suspend for QCA6390 PCI devicesCarl Huang
Now that all the needed pieces are in place implement suspend support QCA6390 PCI devices. All other devices will return -EOPNOTSUPP during suspend. The suspend is implemented by switching the firmware to WoW mode during suspend, so the firmware will be running on low power mode while host is in suspend. At the moment we are not able to shutdown and fully power off the device due to bugs in MHI subsystem, so WoW mode is a workaround for the time being. During suspend we enable WoW mode, disable CE irq and DP irq, then put MHI to suspend state. During resume, driver resumes MHI firstly, then enables CE irq and dp IRQ, and sends WoW wakeup command to firmware.

2020-10-01ath11k: enable shadow register configuration and accessCarl Huang
To enable shadow register access, host needs to pass shadow register configuration to firmware via qmi message. Host also needs to update ring's HP or TP address to shadow register address. The write operation to shadow register will be forwarded to target register by hardware automatically, and the write operation to shadow register is permitted even when the target is in power save or sleep mode. Update the shadow config whenever power up happens. This feature is controlled by hw parameter supports_shadow_regs which is only enabled for QCA6390.

2019-11-25ath11k: driver for Qualcomm IEEE 802.11ax devicesKalle Valo
ath11k is a new driver for Qualcomm IEEE 802.11ax devices, first supporting only IPQ8074 SoC using the shared memory AHB bus. ath11k uses mac80211 and supports AP, Station and Mesh modes. Even though ath11k has some similar code as with ath10k (especially the WMI layer) it was concluded to be simpler to have a "clean start" for ath11k code base and not try to share the code with ath10k. This makes maintenance easier and avoids major changes in ath10k, which would have significantly increased the risk of regressions in existing setups. Even though the driver is very similar with ath10k but there are major differences as well. The datapath is completely different. ath11k supports multiple MACs, called "soc" in the firmware interface. And there's only one WMI interface to support. Currently ath11k supports only IEEE 802.11ac mode, but patches for 802.11ax are available and they will be submitted after ath11k is accepted to upstream. The firmware images are available from ath11k-firmware repository but they will be also submitted to linux-firmware: https://github.com/kvalo/ath11k-firmware This was tested with firmware version WLAN.HK.2.1.0.1-00629-QCAHKSWPL_SILICONZ-1.
