Subject: [PATCH] mt76: mt7921: Disable powersave features by default
|
||
|
|
|
||
|
|
This brings WiFi latency down considerably and makes latency consistent by
|
||
|
|
disabling runtime PM and typical powersave features by default. The actual
|
||
|
|
power consumption difference is inconsequential on desktops and laptops,
|
||
|
|
while the performance difference is monumental. Latencies of 20+ ms are no
|
||
|
|
longer observed after this change, and the connection is much more stable.
