This makes the code clearer since set11nRateFlags currently sets both the rate flags and chain sel. This may also be required for QCN550x support, where the rate flags and chain sel are in separate fields. This change does not appear to affect the final binary. Signed-off-by:

When more clients (128) are connected, the UL data traffic KPI measurement is low compared to single client. This issue is due to more CPU cycles spent on the peer lookup operation with more clients. So reduce the peer lookup operation by modifying the linear based lookup operation into the rhash based lookup operation. This improve the peak throughput measurement. Since this is a software algorithm change, it is applicable for all the platforms.

Sometimes it has a variant value which read from DT or SMBIOS by ath11k, and meanwhile it does not have the matched board name in board-2.bin, then it will failed at boot up phase. Add fallback board name which removed variant value and search again in board-2.bin when failed with variant and try to load the board data again to increase boot up success rate. dmesg log after this patch: [169547.248472] ath11k_pci 0000:05:00.0: boot using board name 'bus=pci,vendor=17cb,device=1103,subsystem-vendor=17cb,subsystem-device=3374,qmi-chip-id=2,qmi-board-id=262,variant=test' [169547.248565] ath11k_pci 0000:05:00.0: boot firmware request ath11k/WCN6855/hw2.0/board-2.bin size 180324 [169547.248568] ath11k_pci 0000:05:00.0: board name [169547.248570] ath11k_pci 0000:05:00.0: 00000000: 62 75 73 3d 70 63 69 2c 76 65 6e 64 6f 72 3d 31 bus=pci,vendor=1 [169547.248571] ath11k_pci 0000:05:00.0: 00000010: 37 63 62 2c 64 65 76 69 63 65 3d 31 31 30 33 2c 7cb,device=1103, [169547.248572] ath11k_pci 0000:05:00.0: 00000020: 73 75 62 73 79 73 74 65 6d 2d 76 65 6e 64 6f 72 subsystem-vendor [169547.248574] ath11k_pci 0000:05:00.0: 00000030: 3d 31 37 63 62 2c 73 75 62 73 79 73 74 65 6d 2d =17cb,subsystem- [169547.248575] ath11k_pci 0000:05:00.0: 00000040: 64 65 76 69 63 65 3d 33 33 37 34 2c 71 6d 69 2d device=3374,qmi- [169547.248576] ath11k_pci 0000:05:00.0: 00000050: 63 68 69 70 2d 69 64 3d 32 2c 71 6d 69 2d 62 6f chip-id=2,qmi-bo [169547.248577] ath11k_pci 0000:05:00.0: 00000060: 61 72 64 2d 69 64 3d 32 36 32 ard-id=262 [169547.248578] ath11k_pci 0000:05:00.0: board name [169547.248579] ath11k_pci 0000:05:00.0: 00000000: 62 75 73 3d 70 63 69 2c 76 65 6e 64 6f 72 3d 31 bus=pci,vendor=1 [169547.248581] ath11k_pci 0000:05:00.0: 00000010: 37 63 62 2c 64 65 76 69 63 65 3d 31 31 30 33 2c 7cb,device=1103, [169547.248582] ath11k_pci 0000:05:00.0: 00000020: 73 75 62 73 79 73 74 65 6d 2d 76 65 6e 64 6f 72 subsystem-vendor [169547.248583] ath11k_pci 0000:05:00.0: 00000030: 3d 31 37 63 62 2c 73 75 62 73 79 73 74 65 6d 2d =17cb,subsystem- [169547.248584] ath11k_pci 0000:05:00.0: 00000040: 64 65 76 69 63 65 3d 33 33 37 34 2c 71 6d 69 2d device=3374,qmi- [169547.248585] ath11k_pci 0000:05:00.0: 00000050: 63 68 69 70 2d 69 64 3d 32 2c 71 6d 69 2d 62 6f chip-id=2,qmi-bo [169547.248587] ath11k_pci 0000:05:00.0: 00000060: 61 72 64 2d 69 64 3d 32 36 36 ard-id=266 [169547.248588] ath11k_pci 0000:05:00.0: board name [169547.248589] ath11k_pci 0000:05:00.0: 00000000: 62 75 73 3d 70 63 69 2c 76 65 6e 64 6f 72 3d 31 bus=pci,vendor=1 [169547.248590] ath11k_pci 0000:05:00.0: 00000010: 37 63 62 2c 64 65 76 69 63 65 3d 31 31 30 33 2c 7cb,device=1103, [169547.248591] ath11k_pci 0000:05:00.0: 00000020: 73 75 62 73 79 73 74 65 6d 2d 76 65 6e 64 6f 72 subsystem-vendor [169547.248592] ath11k_pci 0000:05:00.0: 00000030: 3d 31 37 63 62 2c 73 75 62 73 79 73 74 65 6d 2d =17cb,subsystem- [169547.248594] ath11k_pci 0000:05:00.0: 00000040: 64 65 76 69 63 65 3d 33 33 37 34 2c 71 6d 69 2d device=3374,qmi- [169547.248595] ath11k_pci 0000:05:00.0: 00000050: 63 68 69 70 2d 69 64 3d 31 38 2c 71 6d 69 2d 62 chip-id=18,qmi-b [169547.248596] ath11k_pci 0000:05:00.0: 00000060: 6f 61 72 64 2d 69 64 3d 32 36 36 oard-id=266 [169547.248597] ath11k_pci 0000:05:00.0: failed to fetch board data for bus=pci,vendor=17cb,device=1103,subsystem-vendor=17cb,subsystem-device=3374,qmi-chip-id=2,qmi-board-id=262,variant=test from ath11k/WCN6855/hw2.0/board-2.bin [169547.248476] ath11k_pci 0000:05:00.0: boot using board name 'bus=pci,vendor=17cb,device=1103,subsystem-vendor=17cb,subsystem-device=3374,qmi-chip-id=2,qmi-board-id=262' [169547.248634] ath11k_pci 0000:05:00.0: boot firmware request ath11k/WCN6855/hw2.0/board-2.bin size 180324 [169547.248636] ath11k_pci 0000:05:00.0: board name [169547.248637] ath11k_pci 0000:05:00.0: 00000000: 62 75 73 3d 70 63 69 2c 76 65 6e 64 6f 72 3d 31 bus=pci,vendor=1 [169547.248638] ath11k_pci 0000:05:00.0: 00000010: 37 63 62 2c 64 65 76 69 63 65 3d 31 31 30 33 2c 7cb,device=1103, [169547.248639] ath11k_pci 0000:05:00.0: 00000020: 73 75 62 73 79 73 74 65 6d 2d 76 65 6e 64 6f 72 subsystem-vendor [169547.248641] ath11k_pci 0000:05:00.0: 00000030: 3d 31 37 63 62 2c 73 75 62 73 79 73 74 65 6d 2d =17cb,subsystem- [169547.248642] ath11k_pci 0000:05:00.0: 00000040: 64 65 76 69 63 65 3d 33 33 37 34 2c 71 6d 69 2d device=3374,qmi- [169547.248643] ath11k_pci 0000:05:00.0: 00000050: 63 68 69 70 2d 69 64 3d 32 2c 71 6d 69 2d 62 6f chip-id=2,qmi-bo [169547.248645] ath11k_pci 0000:05:00.0: 00000060: 61 72 64 2d 69 64 3d 32 36 32 ard-id=262 [169547.248646] ath11k_pci 0000:05:00.0: boot found match for name 'bus=pci,vendor=17cb,device=1103,subsystem-vendor=17cb,subsystem-device=3374,qmi-chip-id=2,qmi-board-id=262' [169547.248647] ath11k_pci 0000:05:00.0: boot found board data for 'bus=pci,vendor=17cb,device=1103,subsystem-vendor=17cb,subsystem-device=3374,qmi-chip-id=2,qmi-board-id=262' [169547.248649] ath11k_pci 0000:05:00.0: using board api 2 Tested-on: WCN6855 hw2.0 PCI WLAN.HSP.1.1-03125-QCAHSPSWPL_V1_V2_SILICONZ_LITE-3 Signed-off-by:

In Qualcomm ARM platforms there is WL_EN pin and other power regulators which can be controlled at platform side to completely reset the chip. For most of x86 and other platforms, the chip is connected via PCIe M.2 interface, and there is no way to control WL_EN pin. Instead the host driver needs to reset the chip via PCIE_SOC_GLOBAL_RESET hardware register, just like ath11k does currently. But when using PCIE_SOC_GLOBAL_RESET there are some hardware registers which are not cleared/restored. To handle those cases we can enable PLATFORM_CAP_PCIE_GLOBAL_RESET QMI host capability to tell the firmware to do some platform specific operations after firmware download. This does not fix any known issues, but is recommended by the firmware team, so enable the capability on QCA6390 and WCN6855 PCI devices. It is currently unclear if this should be enabled also on QCN9074, so leave it disabled for now. On AHB devices this is not needed as they don't use PCIE_SOC_GLOBAL_RESET.

ieee80211_reconfig() of mac80211 is the main function for recovery of each ieee80211_hw and ath11k, and ath11k_core_reconfigure_on_crash() is the main function for recovery of ath11k_base, it has more than one ieee80211_hw and ath11k for each ath11k_base, so it need to add synchronization between them, otherwise it has many issue. For example, when ath11k_core_reconfigure_on_crash() is not complete, mac80211 send a hw scan request to ath11k, it leads firmware crash, because firmware has not been initialized at that moment, firmware is only finished downloaded and loaded, it can not receive scan command.

Currently ath11k has device recovery logic, it is introduced by this patch "ath11k: Add support for subsystem recovery" which is upstream by https://git.kernel.org/pub/scm/linux/kernel/git/kvalo/ath.git/commit/?h=ath11k-bringup&id=3a7b4838b6f6f234239f263ef3dc02e612a083ad. The patch is for AHB devices such as IPQ8074, it has remote proc module which is used to download the firmware and boots the processor which firmware is running on. If firmware crashed, remote proc module will detect it and download and boot firmware again. Below command will trigger a firmware crash, and then user can test feature of device recovery. Test command: echo assert > /sys/kernel/debug/ath11k/qca6390\ hw2.0/simulate_fw_crash echo assert > /sys/kernel/debug/ath11k/wcn6855\ hw2.0/simulate_fw_crash Unfortunately, QCA6390 is PCIe bus, it does not have the remote proc module, it use mhi module to communicate between firmware and ath11k. So ath11k does not support device recovery for QCA6390 currently. This patch is to add the extra logic which is different for QCA6390. When firmware crashed, MHI_CB_EE_RDDM event will be indicate by firmware and then ath11k_mhi_op_status_cb which is the callback of mhi_controller will receive the MHI_CB_EE_RDDM event, then ath11k will start to do recovery process, ath11k_core_reset() calls ath11k_hif_power_down()/ath11k_hif_power_up(), then the mhi/ath11k will start to download and boot firmware. There are some logic to avoid deadloop recovery and two simultaneous recovery operations. And because it has muti-radios for the soc, so it add some logic in ath11k_mac_op_reconfig_complete() to make sure all radios has reconfig complete and then complete the device recovery. Also it add workqueue_aux, because ab->workqueue is used when receive ATH11K_QMI_EVENT_FW_READY in recovery process(queue_work(ab->workqueue, &ab->restart_work)), and ath11k_core_reset will wait for max ATH11K_RESET_TIMEOUT_HZ for the previous restart_work finished, if ath11k_core_reset also queued in ab->workqueue, then it will delay restart_work of previous recovery and lead previous recovery fail. ath11k recovery success for QCA6390/WCN6855 after apply this patch.

ath11k_peer_find_by_addr states via lockdep that ab->base_lock must be held when calling that function in order to protect the list. All callers except ath11k_mac_op_unassign_vif_chanctx have that lock acquired when calling ath11k_peer_find_by_addr. That lock is also not transitively held by a path towards ath11k_mac_op_unassign_vif_chanctx. The solution is to acquire the lock when calling ath11k_peer_find_by_addr inside ath11k_mac_op_unassign_vif_chanctx. I am currently working on a static analyser to detect missing locks and this was a reported case. I manually verified the report by looking at the code, but I do not have real hardware so this is compile tested only. Fixes: 701e48a4 ("ath11k: add packet log support for QCA6390") Signed-off-by:

Currently after the hardware restart triggered from the driver, the station interface connection remains intact, since a disconnect trigger is not sent to userspace. This can lead to a problem in targets where the wifi mac sequence is added by the firmware. After the target restart, its wifi mac sequence number gets reset to zero. Hence AP to which our device is connected will receive frames with a wifi mac sequence number jump to the past, thereby resulting in the AP dropping all these frames, until the frame arrives with a wifi mac sequence number which AP was expecting. To avoid such frame drops, its better to trigger a station disconnect upon target hardware restart which can be done with API ieee80211_reconfig_disconnect exposed to mac80211. The other targets are not affected by this change, since the hardware params flag is not set.

It is not recommened to use platform_get_resource(pdev, IORESOURCE_IRQ) for requesting IRQ's resources any more, as they can be not ready yet in case of DT-booting. platform_get_irq() instead is a recommended way for getting IRQ even if it was not retrieved earlier. It also makes code simpler because we're getting "int" value right away and no conversion from resource to int is required. Reported-by:

Implement basic WoW functionalities such as magic-packet, disconnect and pattern. The logic is very similar to ath10k.

This patch increases the number of RX-FIFOs to 3 and the max TX-FIFO depth to 16. This leads to the following default ring configuration. CAN-2.0 mode: | FIFO setup: TEF: 0x400: 8*12 bytes = 96 bytes | FIFO setup: RX-0: FIFO 1/0x460: 32*20 bytes = 640 bytes | FIFO setup: RX-1: FIFO 2/0x6e0: 32*20 bytes = 640 bytes | FIFO setup: RX-2: FIFO 3/0x960: 16*20 bytes = 320 bytes | FIFO setup: TX: FIFO 4/0xaa0: 8*16 bytes = 128 bytes | FIFO setup: free: 224 bytes CAN-FD mode: | FIFO setup: TEF: 0x400: 4*12 bytes = 48 bytes | FIFO setup: RX-0: FIFO 1/0x430: 16*76 bytes = 1216 bytes | FIFO setup: RX-1: FIFO 2/0x8f0: 4*76 bytes = 304 bytes | FIFO setup: TX: FIFO 3/0xa20: 4*72 bytes = 288 bytes | FIFO setup: free: 192 bytes With the previously added ethtool ring configuration support the RAM on the chip can now be runtime configured between RX and TX buffers.

This patch adds RX IRQ coalescing support to the driver. The mcp251xfd chip doesn't support proper hardware based coalescing, so this patch tries to implemented it in software. The RX-FIFO offers a "FIFO not empty" interrupt, which is used if no coalescing is active. With activated RX IRQ coalescing the "FIFO not empty" interrupt is disabled in the RX IRQ handler and the "FIFO half full" or "FIFO full interrupt" (depending on RX max coalesced frames IRQ) is used instead. To avoid RX CAN frame starvation a hrtimer is setup with RX coalesce usecs IRQ,on timer expiration the "FIFO not empty" is enabled again. Support for ethtool configuration is added in the next patch.

So far the configuration of the hardware FIFOs is hard coded and depend only on the selected CAN mode (CAN-2.0 or CAN-FD).

Tony Nguyen says: ==================== ice: GTP support in switchdev Marcin Szycik says: Add support for adding GTP-C and GTP-U filters in switchdev mode. To create a filter for GTP, create a GTP-type netdev with ip tool, enable hardware offload, add qdisc and add a filter in tc: ip link add $GTP0 type gtp role <sgsn/ggsn> hsize <hsize> ethtool -K $PF0 hw-tc-offload on tc qdisc add dev $GTP0 ingress tc filter add dev $GTP0 ingress prio 1 flower enc_key_id 1337 \ action mirred egress redirect dev $VF1_PR By default, a filter for GTP-U will be added. To add a filter for GTP-C, specify enc_dst_port = 2123, e.g.: tc filter add dev $GTP0 ingress prio 1 flower enc_key_id 1337 \ enc_dst_port 2123 action mirred egress redirect dev $VF1_PR Note: outer IPv6 offload is not supported yet. Note: GTP-U with no payload offload is not supported yet. ICE COMMS package is required to create a filter as it contains GTP profiles. Changes in iproute2 [1] are required to be able to add GTP netdev and use GTP-specific options (QFI and PDU type).
