I have problems in the device probing on the E55, and I need some hints here. I am at the very starting point of the SCSI driver development, and other (Rayn) will also need this for MUX (serial), etc.... The E55 is a machine of the type "SYSTEM MAP TYPE". I instrumented the code to read out the values and elements at the inventory probing. I will append the log of my "debug helps", they are quite self explaining. The `walk_central_bus()' calls seems to do correct work. It finds the basic elements on my E55: On the "56" the bus converter On "62" and "63" components on the system (main) board - "62" is the CPU, "63" the Memory The search was started at the "60". My problem now. The `walk_lower_bus()' under the device "56" cannot find any further devices. Seen on PDC or HP-UX, under "56/52" the SCSI controller is present, further the parallel interface and the serial MUX also should be found. Do we use the wrong search address here, taken from io_io_low of the `struct bc_module'. Do we access it in a wrong way ? Is THIS structure documented in any of the PARISC documents, other- wise, where does this structure come from ? I hope you have some hints here ...
