QCA9074 problem on rk3568

QCA9074 problem on rk3568

[Doug Brewer]

Hi,

I tried to install linux kernel 6.3-rc7 on my rk3568 evb.  It seems there's
a problem about MHI:

[   11.340558] ath11k_pci 0002:01:00.0: BAR 0: assigned [mem 0x380000000-0x3801f

[   60.568488] ath11k_pci 0002:01:00.0: failed to init core: -110

Any idea how to fix it?  Thanks.

I would first check that the firmware files are not corrupted.

The firmware files look good, thanks.

Indeed, the firmware files don't seem to be corrupted. This is a weird
problem, I don't recall seeing anything like this before. Some other
ideas to try out:

* if you have access to the Qualcomm in-house QSDK driver (don't know
  what they call it nowadays) trying that would be good for ruling out
  hardware problems

* try older kernel

* try older firmware

* try the QCN9074 on a different platform

But these are just shots in the dark, I can't really guess what the
problem could be. The error comes from the very early during driver
initialisation so most likely a low level issue. I don't have QCN9074 in
my testbed so of course this could be a simple regression somewhere as
well.
