ath10k: Missing airtime scheduler parts

ath10k: Missing airtime scheduler parts

[-- Attachment #1.1: Type: text/plain, Size: 569 bytes --]

Hi,

I was asked what parts are currently missing for (a better) airtime fairness 
with ath10k. I know that the AQL were merged and enabled for ath10k (and 
mt76). But there was also the virtual time-based airtime scheduler [1] which 
was proposed. I think the development on that one didn't continue since last 
year.

Maybe someone else knows if there were some other parts worked on which I've 
am missed and which were not yet merged.

Kind regards,
	Sven

I did recently rebase that patch to the current mac80211-next, actually.
Sent it off to Felix for some testing, but if you wan to give it a go I
can post it to the list as well :)

I don't think there have been any other patches being actively worked
on, but I seem to recall something about AQL (partly?) breaking airtime
fairness because the scheduler only keeps fairness between stations that
are actually scheduled, and AQL interrupting that...

Thank you for the offer. But I doubt that I will find time for it before next 
year.

Kind regards,

Alright, fair enough; I'll give Felix a chance to test it first, then... :)
