2023-09-30wifi: mt76: mt7925: add Mediatek Wi-Fi7 driver for mt7925 chipsDeren Wu
Add mt7925, a new mac80211 driver for the MediaTek Wi-Fi 7 (802.11be) device Filogic 360, which can support Station, AP, P2P, and monitor modes. Filogic 360 supports max 4096-QAM/160MHz radio operation at 6 GHz, 5 GHz, or 2.4 GHz with 2x2 antennas. This chip supports PCIe and USB bus type. mt7925 supports Wi-Fi 6E and EHT rate with single link only at this moment, whereas Wi-Fi 7 and its specific features are working in progress. They will be introduced in further patches. The driver is build tested by Intel's kernel test robot with both GCC and Clang with several architecture. Sparse reports no warnings. There are multiple authors, they are listed in alphabetical order below.

2023-09-30wifi: mt76: Drop unnecessary error check for debugfs_create_dir()Jinjie Ruan
debugfs_create_dir() returns ERR_PTR and never return NULL. As Russell suggested, this patch removes the error checking for debugfs_create_dir(). This is because the DebugFS kernel API is developed in a way that the caller can safely ignore the errors that occur during the creation of DebugFS nodes. The debugfs APIs have a IS_ERR() judge in start_creating() which can handle it gracefully. So these checks are unnecessary.

2023-09-30wifi: mt76: use atomic iface iteration for pre-TBTT workJohannes Berg
In addition to the previous series I posted, over time I'd also like to get rid of the iflist_mtx in mac80211. That isn't easy now since lots of places use iteration and would have to be audited, but even a cursory look suggests that mt76 might be more problematic than most since holding the wiphy lock for the latency-sensitive pre-TBTT work could be an issue. Convert the pre-TBTT work to use atomic iteration and then sending the device commands outside of it.

It was reported that this can cause the PSE hang issues, even with a low number of fragments. Link: https://github.com/openwrt/mt76/issues/793#issuecomment-1676529138 Signed-off-by: Felix Fietkau <nbd@nbd.name>

2023-09-30wifi: mt76: mt7603: improve stuck beacon handlingFelix Fietkau
Before preparing the new beacon, check the queue status, flush out all previous beacons and buffered multicast packets, then (if necessary) try to recover more gracefully from a stuck beacon condition by making a less invasive attempt at getting the MAC un-stuck.

2023-09-30wifi: mt76: mt7603: improve watchdog reset reliablityFelix Fietkau
Only trigger PSE reset if PSE was stuck, otherwise it can cause DMA issues. Trigger the PSE reset while DMA is fully stopped in order to improve reliabilty. Fixes: c8846e101502 ("mt76: add driver for MT7603E and MT7628/7688") Signed-off-by: Felix Fietkau <nbd@nbd.name>
2023-09-30wifi: mt76: mt7603: rework/fix rx pse hang checkFelix Fietkau
It turns out that the code in mt7603_rx_pse_busy() does not detect actual hardware hangs, it only checks for busy conditions in PSE. A reset should only be performed if these conditions are true and if there is no rx activity as well. Reset the counter whenever a rx interrupt occurs. In order to also deal with a fully loaded CPU that leaves interrupts disabled with continuous NAPI polling, also check for pending rx interrupts in the function itself.
