Host sends wmi command to allow hardware enter idle power save mode in ath11k_mac_op_start function. hw parameter idle_ps indicates whether idle power save is supported. Tested-on: QCA6390 hw2.0 PCI WLAN.HST.1.0.1-01740-QCAHSTSWPLZ_V2_TO_X86-1 Signed-off-by:

For QCA6390, Start a timer to update CE pipe 4 ring HP when shadow register is enabled. Its' to avoid that HP isn't updated to target register. Tested-on: QCA6390 hw2.0 PCI WLAN.HST.1.0.1-01740-QCAHSTSWPLZ_V2_TO_X86-1 Signed-off-by:

The timer is to check if TCL HP isn't updated to target. The timer will postpone itself if there are TX operations during the interval, otherwise the timer handler updates the HP again so the index value in HP register will be forwarded to target register, and the timer stops afterwards.

For QCA6390, set wmi credit to 1 to avoid back-to-back write to shadow register when shadow register is enabled. Tested-on: QCA6390 hw2.0 PCI WLAN.HST.1.0.1-01740-QCAHSTSWPLZ_V2_TO_X86-1 Signed-off-by:

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.

For QCA6390, host can read and write registers below unwindowed address directly without programming the window register. For registers below bar0 + 4k - 32, host can read and write regardless of the power save state. Shadow registers are located below bar0 + 4K - 32. Before MHI power up, there is no need to wakeup MHI so ini_done is added to indicate it. Tested-on: QCA6390 hw2.0 PCI WLAN.HST.1.0.1-01740-QCAHSTSWPLZ_V2_TO_X86-1 Signed-off-by:

With QCA6390 when doing rmmod the kernel crashed. The reason was that the destroy functions ath11k_debugfs_pdev_destroy() and ath11k_debugfs_soc_destroy() accidentally had swapped the debugfs directories and ath11k_debugfs_soc_destroy() was removing an already removed directory, which crashed the kernel. The source of confusion is badly named function and variable names. I think the best way to clean this up is actually to merge the corresponding functions, but that's for another patch. Let's first just fix the crash.

Add packet log support for QCA6390, otherwise the data connection will stall within a minute or so. Enable it via debugfs and use trace-cmd to capture the pktlogs. echo 0xffff 1 > /sys/kernel/debug/ath11k/qca6390\ hw2.0/mac0/pktlog_filter The mon status ring doesn't support interrupt so far, so host starts a timer to reap this ring. The timer handler also reaps the rxdma_err_dst_ring in case of monitor mode. As QCA6390 requires bss created ahead of starting vdev, so check vdev_start_delay for monitor mode. For QCA6390, it uses wbm_desc_rel_ring to return descriptors. It also uses rx_refill_buf_ring to fill mon buffer instead of rxdma_mon_buf_ring.

Michael Chan says: ==================== bnxt_en: Update for net-next. This patch series adds 2 main features to the bnxt_en driver: 200G link speed support and FEC support with some refactoring of the link speed logic. The firmware interface is updated to have proper support for these 2 features. The ethtool preset max channel value is also adjusted properly to account for XDP and TCs. ==================== Signed-off-by: -
Michael Chan authored
The current logic that calculates the preset maximum value for combined channel does not take into account the rings used for XDP and mqprio TCs. Each of these features will reduce the number of TX rings. Add the logic to divide the TX rings accordingly based on whether the device is currently in XDP mode and whether TCs are in use.

PORT_PHY_CONFIG is always sent with REQ_FLAGS_RESET_PHY set. This flag must be set in order for the firmware to institute the requested PHY change immediately, but it results in a link flap. This is unnecessary and results in an improved user experience if the PHY reconfiguration is avoided when the user requested speed does not constitute a change. Signed-off-by:

On some 200G dual port NICs, if one port is configured to 200G, firmware will disable the ethernet link on the other port. Firmware will send notification to the driver for the disabled port when this happens. Define a new field in the link_info structure to keep track of this state. The new phy_state field replaces the unused loop_back field. Log a message when the phy_state changes state. In the disabled state, disallow any PHY configurations on the disabled port as the firmware will fail all calls to configure the PHY in this state. Reviewed-by:

The firmware interface has added support for new link speeds using PAM4 modulation. Expand the bnxt_link_info structure to closely mirror the new firmware structures. Add logic to copy the PAM4 capabilities and settings from the firmware. Signed-off-by:

Edwin Peer authored
It will be necessary to update more than one field in the link_info structure when PAM4 speeds are added in a later patch. Instead of merely translating ethtool speed values to firmware speed values, change the responsiblity of this function to update all the necessary link_info fields required to force the speed change to the desired ethtool value. This also reduces code duplication somewhat at the two call sites, which otherwise both have to independently update link_info fields to turn off auto negotiation advertisements. Also use the appropriate REQ_FORCE_LINK_SPEED definitions. These happen to have the same values, but req_link_speed is utilimately passed as force_link_speed in HWRM_PORT_PHY_CFG which is not defined in terms of REQ_AUTO_LINK_SPEED. Reviewed-by:

Extract the code for determining an advertised speed is no longer supported into a separate function. This will avoid some code duplication in a later patch when supporting PAM4 speeds, since these speeds are specified in a separate field. Reviewed-by:

The main changes include FEC, ECN statistics, HWRM_PORT_PHY_QCFG response size reduction, and a new counter added to ctx_hw_stats_ext struct to support the new 58818 chip. The ctx_hw_stats_ext structure is now the superset supporting the new 58818 chips and the prior P5 chips. Add a new flag to identify the new chip and use constants for the chip specific ring statistics sizes instead of the size of the structure. Because the HWRM_PORT_PHY_QCFG response structure size has shrunk back to 96 bytes, the workaround added earlier to limit the size of this message for forwarding to the VF can be removed.
