2025-01-27wifi: mt76: move napi_enable() from under BHJakub Kicinski
mt76 does a lot of: local_bh_disable(); napi_enable(...napi); napi_schedule(...napi); local_bh_enable(); local_bh_disable() is not a real lock, its most likely taken because napi_schedule() requires that we invoke softirqs at some point. napi_enable() needs to take a mutex, so move it from under the BH protection. Fixes: 413f0271f396 ("net: protect NAPI enablement with netdev_lock()") Reported-by: Dan Carpenter <dan.carpenter@linaro.org> Link: https://lore.kernel.org/dcfd56bc-de32-4b11-9e19-d8bd1543745d@stanley.mountain Reviewed-by: Eric Dumazet <edumazet@google.com> Link: https://patch.msgid.link/20250124031841.1179756-8-kuba@kernel.org Signed-off-by: Jakub Kicinski <kuba@kernel.org>
2025-01-14wifi: mt76: mt7925: add handler to hif suspend/resume eventQuan Zhou
When the system suspend or resume, the WiFi driver sends an hif_ctrl command to the firmware and waits for an event. Due to changes in the event format reported by the chip, the current mt7925's driver does not account for these changes, resulting in command timeout. Add flow to handle hif_ctrl event to avoid command timeout. We also exented API mt76_connac_mcu_set_hif_suspend for connac3 this time.

2023-04-17wifi: mt76: move irq_tasklet in mt76_dev structLorenzo Bianconi
irq_tasklet struct is used by most of the drivers (e.g. mt7915, mt7921, mt7615, mt7663 and mt7996) so move it in common code. Signed-off-by: Lorenzo Bianconi <lorenzo@kernel.org> Signed-off-by: Felix Fietkau <nbd@nbd.name>
2021-10-20mt76: disable BH around napi_schedule() callsFelix Fietkau
napi_schedule() can call __raise_softirq_irqoff(), which can perform softirq handling, so it must not be called in a pure process context with BH enabled. Signed-off-by: Felix Fietkau <nbd@nbd.name>
