===== ath10k firmware =====

The ath10k firmware images are available from [[https://git.kernel.org/cgit/linux/kernel/git/firmware/linux-firmware.git/|linux-firmware.git]] which all common Linux distributions should install by default. Latest firmware images can be downloaded from [[https://git.codelinaro.org/clo/ath-firmware/ath10k-firmware|ath10k-firmware.git]] from which they get eventually pushed to [[https://git.kernel.org/cgit/linux/kernel/git/firmware/linux-firmware.git/|linux-firmware.git]].

===== Firmware API versions =====

Because firmware changes between versions we have introduced firmware API concept to ath10k. This makes it possible to support different versions of ath10k. 


==== Firmware API 1 ====

The first version. Firmware images are in separate files: firmware.bin and otp.bin. There's no FW IE support. Deprecated since March 2014 and removed on March 2016.


==== Firmware API 2 ====

Embedding both firmware and otp images into same file firmware-2.bin. Firmware meta data provided through FW IE. Added in commit 1a222435a dated Sep 27 2013, for Linux 3.13. Deprecated, no new firmware releases use this anymore.

==== Firmware API 3 ====

Adding support for 10.2 firmware for QCA988X and ATH10K_FW_FEATURE_WMI_10_2 feature for 10.2 WMI mappings. Added in commit 24c88f7807fb7 dated Jul 27 2014. Deprecated, no new firmware releases use this anymore.
