I can still observe random performance drops on my setup. Those drops are very rare after applying those:
mt76x02: assure we update gain after scan mt76x02: run calibration after scanning mt76x0: do not overwrite other MT_BBP(AGC, 8) fields but sill happened in Felix tree up to: 79864387b0a0 mt76x0: pci: add DFS support I did not notice them on linux-4.20 with 3 above fixes and following patches: 1737618972d6 mt76x0: phy: unify calibration between mt76x0u and mt76x0e c9540a53b257 mt76x2u: introduce mac workqueue support 9ed42cfca329 mt76x0: use mt76x02_mac_work as stats handler f6f36ffc6da8 mt76x0: use shared debugfs implementation 1ef5b4893baa mt76: move mt76x02_debugfs in mt76x02-lib module 210ec41d92a0 mt76: move mt76x02_mac_work routine in mt76x02-lib module 9e72f73dc692 mt76x0: pci: add get_survey support 70ef7506c741 mt76x0: phy: improve code readability in initvals_phy.h 30ec3a3558c8 mt76x0: phy: simplify rf configuration routines 37385b8f96bc mt76x0: phy: use proper name convention 7936959c4544 mt76x2u: align channel gain logic to mt76x2 one 0129c6cf5577 mt76x2: align mt76x2 and mt76x2u firmware Since is hard to reproduce the problem, I was not able to identify offended commit. However looking at the history there are planty of commits like: mt76: move XXX in mt76x02-lib module which does not only move the code, but change the behavior of the mt76x0u driver in various ways. Following patches restore some of old mt76x0u behaviour and should do correct thing and do not cause any harm on different setup (AP mode , mt76x2u, mt76x0e), but I did not test them in those setups. Stanislaw Gruszka (4): mt76x02: configure basic rates and fallback on STA mode mt76x02: reserve wcid 0 for global mt76x02: do not set protection on set_rts_threshold callback mt76x02: set protection according to ht capabilities drivers/net/wireless/mediatek/mt76/mt76x02_mac.c | 74 ++++++++++++++++++----- drivers/net/wireless/mediatek/mt76/mt76x02_mac.h | 4 +- drivers/net/wireless/mediatek/mt76/mt76x02_util.c | 24 +++++++- 3 files changed, 84 insertions(+), 18 deletions(-) -- 1.9.3
