Hi Ben
Thanks for your time.
If I want to try ath10k-ct-driver, where I can get stable version?
There has information about pci-e layout.
The device has two PCI-e slots. one is the original pci-e slot of main board
and the other one is the output of pci-e switch.
case 1:one is the original pci-e slot of main board
case 2:one is the output from pci-e switch.
We can get QCA9884 pci-e information (VID and IID) form /sys/bus/pci/device in
case 1 and case 2
ath10k driver always work in case 1 and always get the firmware crash message
in case 2.
Does ath10k driver have any limits about pci-e layout?
The most likely way for it to work is to use one of our kernels,
the 4.13 being the most stable and well tested at this point.
The 4.16 should be OK too, but it is less tested.

Or, you can try using our stand-alone driver, but it does not work on
all kernels...typically just 4.9, 4.13 and 4.16 or similar.

I don't know of any particular issues with pcie, but I guess there must be some
issue in your case.

I think it might be something like a null-pointer exception, but those do not
create a clean backtrace. If you wanted to use my ath10k-ct driver, it can
sometimes
gather additional info for these types of crashes that lets me know more about
it.
But, if your problem is with backporting a driver anyway, maybe that is not
so much help.
If you could move forward to at least the 4.9 kernel, then likely you will have
better luck with the 9984.
Thanks,
Ben

Hi
I'm porting ath10k drivers for Linux 4.2.8.
Try to bring up QCA9984 wireless PCI-e card.
I have problem with running ath10k driver, firmware load then the kernel
message will show the firmware crashed during boot.
The attachment is the error log.
I also tried firmware ver 10.4-3.2, 10.4-3.3 and 10.4-3.5.3 without success:
same symptoms an same faults.
I can provide more information (logs) to help to figure out: where the problem
is?
You can try my ath10k-ct firmware, send me crash dump if it crashes and I might
can
decode it and tell you why.
