[parisc-linux] "Unknown machine at ..." on N4k

[Joel Soete]

Hi all, 

I just noticed that that in during the "Found devices:" on the the N4k it=
's
mentioned:
[...]
18. DEW BC Runway Port at 0xfffffffffed24000 [36] { 7, 0x0, 0x584, 0x0000=
c
}
19. Unknown machine at 0xfffffffffed25000 [37] { 0, 0x0, 0x5d3, 0x00000
}
20. DEW BC Runway Port at 0xfffffffffed2c000 [44] { 7, 0x0, 0x584, 0x0000=
c
}
21. Unknown machine at 0xfffffffffed2d000 [45] { 0, 0x0, 0x5d3, 0x00000
}

Comparing with ioscan:
[...]
pbc         1  36                      pbc       CLAIMED     BUS_NEXUS 
  Bus Converter
processor   1  37                      processor CLAIMED     PROCESSOR 
  Processor
pbc         3  44                      pbc       CLAIMED     BUS_NEXUS 
  Bus Converter
processor   3  45                      processor CLAIMED     PROCESSOR 
  Processor

The 'Unknown machine' are in fact the cpu.

Any idea where I have to look for to change it?

TIA,
    Joel

It needs to be added to arch/parisc/kernel/hardware.c.
see hp_hardware_list[] declaration :^)

We just need to know what the proper name for the CPU is.

        {HPHW_NPROC,0x5D3,0x4,0x91,"Prelude W+ 540"},

We have this one ...

Strange, I need so to have a more detail look :)

umm not so easy to choose the right thing according to:
<http://www.openpa.net/cpu.html#xwp>
its code name would be "Landshark"

Thanks more,

I suggest just adding another entry to hp_hardware_list[].
It's either a bug in either the PDC implementation or the IO ACD
(Arch Control Doc) we took the initial table from. I'm much more
inclined to believe we transposed/updated the table incorrectly.

Is anybody else has such model to test it?
