Subject: [Codel] [RFCv2 0/3] mac80211: implement fq codel
Date: Wed, 16 Mar 2016 11:17:55 +0100 [thread overview]
Message-ID: <1458123478-1795-1-git-send-email-michal.kazior@tieto.com> (raw)
Hi,
Most notable changes:
* fixes (duh); fairness should work better now,
* EWMA codel target based on estimated service
time,
* new tx scheduling helper with in-flight
duration limiting (same idea Emmanuel
had for iwlwifi),
* added a few debugfs hooks.
* ath10k proof-of-concept that uses the new tx
scheduling (will post results in separate
email)
The patch grew pretty big and I plan on splitting
it before next submission. Any suggestions?
The tx scheduling probably needs more work and
testing. I didn't evaluate how CPU intensive it is
nor how it influences things like peak throughput
(lab conditions et al) yet.
I've uploaded a branch for convenience:
https://github.com/kazikcz/linux/tree/fqmac-rfc-v2
This is based on Kalle's ath tree.
