I've scored myself a new laptop. With that come new problems.

I updated to 4.12.0 to make sure i'm on the latest.

lspci says:

01:00.0 Network controller: Qualcomm Atheros QCA6174 802.11ac Wireless Network Adapter (rev 32)

So relevant bits from dmesg:

I've tried firmware-6 from:

  https://github.com/kvalo/ath10k-firmware/tree/master/QCA6174/hw3.0

Specifically firmware-6.bin_WLAN.RM.4.4.1-00008-QCARMSWP-1. firmware-4.bin also is a no go.

How can I help make this work? I have all the windows .bin's but none of them
match the same header that the Linux fw bin files have (but a chunk of the
binary seems familiar having a quick binary dump of it). There is some
mysterious way of generating the Linux firmware files I can't google for.

I also have some help from the OEM - the engineers who made the laptop (not
the chip wifi maker though). I have already verified which GPIO lines control
RFkill on this device (and they are clear and unkilled by default - both lines
up at 1 and it's confirmed that this means RF is unblocked from the engineers.
It took me a while to figure out their GPIO mapping table/naming onto kernel
GPIO numbering). So the Wifi (an BT actually) should be powered on. It's a
combo chip.

So how can I help. What data do I need to scrounge to provide. How are firmware
files built to work for Linux (based off the windows ones) for ath10k?
