I have finally managed to get our PrPMC800's running as NON-MONARCH and using its built in Ethernet controller. Now I only have to clean up what I have done, and remove all hardwired hacks, in order to do this, I would like comments on the points listed below.
1. I need to find out which of the found Ethernet 82559 chips that belongs to this card. My suggestion is to compare the Ethernet adress returned from a "82559 PORT Dump" command with the value stored in the PrPMC800 NVRAM. 2. All Ethernet chips that are not located on the board should be left alone, how do I do this? 3. prpmc_map_irq needs to be modified to only route interrupts from the built in ethernet. 4. Should I add a configuration option to use the built in ethernet? There is a potential IRQ conflict, since the 82559 will generate PCI INTB requests, and this might lead to conflicts whith the PCI MONARCH. In our case that is not a problem, since we got a slightly modified ADC-PMC2 from AlphaData (http://www.alpha-data.com/), which ensures that the INTB never reaches the PCI bus. 5. I think that it would be a good idea to add some heuristcs to find out what kind of carrier the PrPMC800 is located on, output from the PPC-Bug "ver;e" command on different carriers are most welcome.
