There was some confusion in the forum recently with the assumption that recent builds were using the CT driver/firmware but it was cleared up by BS:

ahm this is no ct driver. its still the same ath10k with own modifications and the firmware is not based on CT. but me and ben share our patches and enhancements. for qca988x is a complete own firmware based on the qca mainline sources with modifications i contributed back to CT. (mainly optimizations). for the QCA99XX based firmwares, its based on CT, but has also own enhancements and optimizations i was contributing back to CT.


Can someone please provide some background on the whole CT vs non-CT firmware/driver for the ATH10K devices? Why are there two different versions for the same chipset? Is one considered to be better for ATH10K devices (i.e. R7800)?

Thanks!

Candela Technlogies or ath10k-ct adds features and fixes bugs, but there may be some remaining.

Everything ath10k on DD-WRT is customized from BrainSlayer, so we are not running anything directly CT.

I have no issues with the new wifi binaries, and they have been changing a lot recently which is always good.

So did Qualcomm outsource their driver development to Candela Tech, or did this company just pick up QCA sources and start building their own version? I'm just wondering how this divergence came to pass.

Do not know the full history behind it, but I assume the latter under NDA.

Vanilla QCA ath10k upstream is maintained available here (driver,sources,tree,linux fw,github).

CT ath10k webpage; involved in network testing and emulation solutions.

BrainSlayer has the access and abilities to create the best of both worlds.

I guess that's why he gets paid the big bucks.
