Currently, when getting a RFKILL interrupt, the transport enters a flow in which it stops the device, disables other interrupts, etc. After stopping the device, the transport resets the hw, and sleeps. During the sleep, a context switch occurs and host commands are sent by upper layers (e.g. mvm) to the fw. This is possible since the op_mode layer and the transport layer hold different mutexes. Since the STATUS_RFKILL bit isn't set, the transport layer doesn't recognize that RFKILL was toggled on, and no commands can actually be sent, so it enqueues the command to the tx queue and sets a timer on the queue. After switching context back to stopping the device, STATUS_RFKILL is set, and then the transport can't send the command to the fw. This eventually results in a queue hang. Fix this by setting STATUS_RFKILL immediately when the interrupt is fired. Signed-off-by: Golan Ben-Ami <golan.ben.ami@intel.com> Signed-off-by: Luca Coelho <luciano.coelho@intel.com> |
