2023-09-13wifi: mt76: mt7915: remove VHT160 capability on MT7915Felix Fietkau1-1/+0
[ Upstream commit 3ec5ac12ac8a4e6b1e085374325a5fbd1b650fd5 ] The IEEE80211_VHT_CAP_EXT_NSS_BW value already indicates support for half-NSS 160 MHz support, so it is wrong to also advertise full 160 MHz support.

2022-12-01wifi: mt76: mt7915: improve accuracy of time_busy calculationRyder Lee1-0/+17
The MIB INFO command is fetching MIB_BUSY_TIME, MIB_TX_TIME, MIB_RX_TIME and MIB_OBSS_AIRTIME from the radio and filling out cc_busy, cc_tx, cc_bss_rx and cc_rx respectively. busy should be >= tx + rx >= tx + bss_rx but we don’t always quite see this. Sometimes tx + rx is a bit higher than busy due to inaccurate accounting, so this patch recalculates numbers to make them more reasonable.

2022-02-24mt76: mt7915e: Fix degraded performance after temporary overheatNicolas Cavallari1-6/+11
mt7915e registers a cooling_device with wrong semantics: 1. cooling_device expect that higher states values should cool more, but mt7915e did the opposite... with the exception of state == 0, which should "disable thermal management", but does not seem to have any effect since the previous state is kept. The result is that when the thermal zone heats up a bit and bumps the cooling_device state from 0 to 1 to cool a bit, the performance is destroyed, and when going back from 1 to 0, the performance stays bad. 2. Reading the cooling_device state does not always return the last written state, but can return the actual hardware throttle state, which is different. This is a problem because the mt7915 firmware actually implement the equivalent of a thermal zone with trip points. Setting the cooling device state actually changes the throttles at each trip point, so the following could occur if the first issue is fixed: - thermal subsystem set state to 100% power (state=0) - mt7915e driver set trip throttles to [100%, 50%, 25%, 12%] - hardware heats up and decides to switch to 50% power - thermal subsystem see that power is 50% (state=50), decide to increase it to 60% (state=40) because the rest of the system is cool. - mt7915e driver set trip throttle to [60%, 30%, 15%, 7%] - hardware thus switches to 30% power [race to the bottom continues...] This patch corrects the semantics of the cooling_device to the one that the thermal subsystem expect it.
