    mailbox: switch to hrtimer for tx_complete polling · 0cc67945
    Sudeep Holla authored
    The mailbox core uses jiffy based timer to handle polling for the
    transmit completion. If the client/protocol have/support notification
    of the last packet transmit completion via ACK packet, then we tick the
    Tx state machine immediately in the callback. However if the client
    doesn't support that mechanism we might end-up waiting for atleast a
    jiffy even though the remote is ready to receive the next request.
    This patch switches the timer used for that polling from jiffy-based
    to hrtimer-based so that we can support polling at much higher time
