Ath11k fails to probe WCN6855 hw2.1 chip: [ 6.983821] ath11k_pci 0000:06:00.0: enabling device (0000 -> 0002) [ 6.983841] ath11k_pci 0000:06:00.0: Unsupported WCN6855 SOC hardware version: 18 17 This is caused by the wrong bit mask setting of hardware major version: for QCA6390/QCN6855, it should be BIT8-11, not BIT8-16, so change the definition to GENMASK(11, 8). Also, add a separate entry for WCN6855 hw2.1 in ath11k_hw_params. Please note that currently WCN6855 hw2.1 shares the same firmwares as hw2.0, so users of this chip need to create a symlink as below: ln -s hw2.0 hw2.1 Tested-on: WCN6855 hw2.1 PCI WLAN.HSP.1.1-01720.1-QCAHSPSWPL_V1_V2_SILICONZ_LITE-1 Tested-on: WCN6855 hw2.0 PCI WLAN.HSP.1.1-01720.1-QCAHSPSWPL_V1_V2_SILICONZ_LITE-1 Tested-on: QCA6390 hw2.0 PCI WLAN.HST.1.0.1-01740-QCAHSTSWPLZ_V2_TO_X86-1 Fixes: 18ac1665e785 ("ath11k: pci: check TCSR_SOC_HW_VERSION") Signed-off-by: Baochen Qiang <quic_bqiang@quicinc.com> --- drivers/net/wireless/ath/ath11k/core.c | 53 ++++++++++++++++++++++++++ drivers/net/wireless/ath/ath11k/core.h | 1 + drivers/net/wireless/ath/ath11k/mhi.c | 1 + drivers/net/wireless/ath/ath11k/pci.c | 16 +++++++- 4 files changed, 69 insertions(+), 2 deletions(-)
