Description [src]

Emitted when Linux FireWire subsystem generates interrupt event. There are three cases for Linux FireWire subsystem to generate the event:

  • When 1394 OHCI hardware generates hardware interrupt as a result of processing the isochronous packet for the buffer chunk marked to generate hardware interrupt.
  • When the number of isochronous packets sent since the last interrupt event reaches one quarter of memory page size (usually 4,096 / 4 = 1,024 packets).
  • When application calls hinoko_fw_iso_ctx_flush_completions() explicitly.
Default handler:

The default handler is called after the handlers added via g_signal_connect().

Available since: 1.0
