QCN9074 mhi Issues

[Thomas Duffy]

I had been waiting for the ath11k driver and QCN9074 firmware to
mature, and it appears that this is the case, as the driver is now in
mainline kernel and the firmware is in linux-kernel.

However, my setup just doesn't work, and I am hoping for some help
troubleshooting.

I have a supermicro X10SDV-4C+-TLN4F board which has a Xeon D-1518
processor that is paired with a Compex WLE3000H2 Wifi 6 5Ghz card.
Vt-d is enabled in BIOS.

I am running Ubuntu 22.04 Server which has kernel 5.15 and thus has the driver.

I have board-2.bin, amss.bin, and m3.bin all in the correct folder
(lib/firmware/ath11k/QCN9074/hw1.0) from
https://github.com/kvalo/ath11k-firmware/tree/master/QCN9074/hw1.0

lspci output shows the card:

06:00.0 Network controller: Qualcomm Device 1104 (rev 01)

The ath11k_pci driver finds and enables the device:

[    9.344266] ath11k_pci 0000:06:00.0: BAR 0: assigned [mem
0xfb200000-0xfb3fffff 64bit]
[    9.344294] ath11k_pci 0000:06:00.0: enabling device (0100 -> 0102)
[    9.369190] ath11k_pci 0000:06:00.0: qcn9074 hw1.0

But then fails to start the device with mhi errors:

[    9.494081] ath11k_pci 0000:06:00.0: failed to set mhi state: POWER_ON(2)
[    9.494087] ath11k_pci 0000:06:00.0: failed to start mhi: -110

[   10.339939] ath11k_pci: probe of 0000:06:00.0 failed with error -110

The dmesg output for mhi is:

[    9.456834] mhi mhi0: Requested to power ON
[    9.457281] mhi mhi0: Power on setup success
[    9.472444] mhi mhi0: Image transfer failed

[    9.482744] mhi mhi0: MHI did not load image over BHI, ret: -5

Does anyone have any suggestions?

Thanks,
