A patch series for the ath11k driver is improving network latency and throughput. The improvements are due to the addition of a queue under mac80211's control, which has resulted in 7x lower latency and 2.2x throughput at identical latency.
Imagine you're playing a game online and your internet connection is slow. That's because the computer is sending data too slowly to the server. The ath11k driver is like a special program that helps the computer send data faster. Recently, some developers made changes to the ath11k driver that made it send data 7 times faster than before. This means that online games and other activities that require fast internet will work better and be more enjoyable.
Analysis
Patch Series Overview
A patch series being worked on for the ath11k mainline wireless networking driver for Qualcomm WiFi 6 / 802.11ax chipsets is yielding 7x lower latency or 2.2x throughput at identical latency. The improvements are due to the addition of a queue under mac80211's control, which has resulted in 7x lower latency and 2.2x throughput at identical latency.
Background
The ath11k driver has been lacking a queue of its own, which has been crippling the network latency with major inefficiencies. Open-source developer Julius Bairaktaris has been addressing this issue by adding a queue under mac80211's control.
What Changed
The patch series adds just over 150 lines of code and includes nine patches. The code is under review on the Linux kernel mailing list. The improvements are due to the addition of a queue under mac80211's control, which has resulted in 7x lower latency and 2.2x throughput at identical latency.
Implications
The improvements to the ath11k driver are significant for users of Qualcomm WiFi 6 / 802.11ax chipsets, as they will experience better network performance and lower latency. The improvements are also a testament to the power of open-source development and the ability of developers to collaborate and improve the Linux kernel.
Key points
- A patch series for the ath11k mainline wireless networking driver is yielding 7x lower latency or 2.2x throughput at identical latency.
- The improvements are due to the addition of a queue under mac80211's control.
- The patch series adds just over 150 lines of code and includes nine patches.
- The code is under review on the Linux kernel mailing list.
If the improvements to the ath11k driver are successful, it could lead to better network performance and lower latency for users of Qualcomm WiFi 6 / 802.11ax chipsets. This could also lead to more developers contributing to the Linux kernel and improving its performance.
However, the improvements to the ath11k driver may not be widely adopted by all users, which could limit their impact. Additionally, the Linux kernel is a complex system, and changes to one component can have unintended consequences elsewhere in the system.
