Subject: [PATCH 0/2] Implement Airtime-based Queue Limit (AQL)
Date: Thu, 3 Oct 2019 23:21:49 -0700 [thread overview]
Message-ID: <20191004062151.131405-1-kyan@google.com> (raw)
This patch series implements Airtime-based Queue Limit (AQL) in the mac80211 and Ath10k driver. It is based on an earlier version from the ChromiumOS tree[0].
This version has been tested with QCA9884 platform with 4.14 kernel. Tests show AQL is able to reduce latency by an order of magnitude in a congested environment without negative impact on the throughput.
