To be clear, the file you’re describing isn’t the driver but the binary firmware blob. The driver (ath10k) is open-source and part of the kernel, and will need to be rebuilt in order to be upgraded.

I do not believe that merely placing the file in this directory is sufficient. You will need to build a new kernel (or at least, rebuild the driver if it is a module) with that new firmware file referenced in the configuration.

This renaming is correct. However, there is another issue, in that the firmware version you mention is not supported yet by the ath10k driver that ships in any released kernel. I believe it will be used in the 4.2 kernel, but they haven’t cut the first RC yet.

If you don’t to wait for a 4.2 kernel, you can build kvalo’s development kernel branch, which should have the necessary changes in it, from:

(People who actually now what they’re doing, please correct me if I’m wrong!)


Thanks,
Matt
