2 Using physical DMA provided by OHCI-1394 FireWire controllers for debugging

9 to the OHCI-1394 specification which defines the controller to be a PCI
12 PCI-Bus master DMA after applying filters defined by the OHCI-1394 driver.
15 ask the OHCI-1394 controller to perform read and write requests on
28 more common hardware such as x86, x86-64 and PowerPC.
34 Together with a early initialization of the OHCI-1394 controller for debugging,

63 Bernhard Kaindl enhanced firescope to support accessing 64-bit machines
64 from 32-bit firescope and vice versa:

74 The latest version of this gdb proxy (fireproxy-0.34) can communicate (not
75 yet stable) with kgdb over an memory-based communication module (kgdbom).

93 Load the firewire-ohci module and check your kernel logs.
100 CardBus and even some Express cards which are fully compliant to OHCI-1394
113 stable connection and has matching connectors (there are small 4-pin and
114 large 6-pin FireWire ports) will do.

147 4) Prepare for debugging with early OHCI-1394 initialization:
162 With the FireWire cable connected, the OHCI-1394 driver on the debugging
166 Then, on the debugging host, run firescope, for example by using -A::
168 firescope -A System.map-of-debug-target-kernel
170 Note: -A automatically attaches to the first non-local node. It only works
173 After having attached to the debug target, press Ctrl-D to view the
174 complete printk buffer or Ctrl-U to enter auto update mode and get an
175 updated live view of recent kernel messages logged on the debug target.
177 Call "firescope -h" to get more information on firescope's options.
