seeking further info on firmware-3

seeking further info on firmware-3

[Robert E. Cochran]

Hi,

I'm testing Linux 3.18-rc5 with a QCA9880 / Compex WLE900VX.

During boot, I'm seeing complaints about not finding firmware-3.bin:

ath10k_pci 0001:03:00.0: Direct firmware load for 
ath10k/QCA988X/hw2.0/firmware-3.bin failed with error -2
ath10k_pci 0001:03:00.0: could not fetch firmware file 
'ath10k/QCA988X/hw2.0/firmware-3.bin': -2


Can someone please confirm that we should be using 
firmware-3.bin_10.2-00082-4-2 from the 10.2 folder on 
https://github.com/kvalo/ath10k-firmware.git
?  When we use this firmware, we see the following during boot:

ath10k_pci 0001:03:00.0: qca988x hw2.0 (0x4100016c, 0x043202ff) fw 
10.2-00082-4-2 api 3 htt 2.1
ath10k_pci 0001:03:00.0: debug 1 debugfs 1 tracing 0 dfs 0 testmode 1



If this isn't the latest & greatest firmware, then where do I find 
firmware-3.bin?


And If I should be using firmware-3.bin_10.2-00082-4-2, then are there 
some release notes available for this?


Finally, please let me know if it's a mistake to be working with 
firmware-3 on the 3.18 kernel.   We're performing some early integration 
testing with this WiFi module, and it's more important to get things 
working as an AP with hostapd than getting the latest cutting edge 
features working.



Thanks,

Bob

You can ignore this warning. ath10k is just telling (in a confusing way)
that it could not find firmware-3.bin and will try firmware-2.bin next.
We should clear up that warning message.

That's good. Using firmware from 10.2 branch is a good idea. But did you
rename it to firmware-2.bin? It should be called firmware-3.bin.

ath10k-firmware.git is the correct location to find the firmware.

Unfortunately there are no firmware release notes available.

The number three in "firmware-3.bin" is just an API number, just like
the soname in shared libraries, to make it possible to have backwards
compatibility with the firmware releases. Instead use version string
like "10.2-00082-4-2" to identify between firmware releases.

And yes, using firmware version 10.2-00082-4-2 is the firmware version I
recommend to use at the moment.
