[parisc-linux] Dump driver: step by step

	Hi.
I've succeded to read with iodc, and at the right place (good news no).
Now I'll try to write. But I prefer to do it on another disk.
So I've found an old scsi SE. I've plugged it. The driver is able
to find the hpa, retrieve the iodc ENTRY_INIT without any pb.
But when calling the ENTRY_INIT with INIT_MOD_DEV or only INIT_DEV
it fail with return code -9. But there is a little pb, I don't
have this return code in documentation. If I believe the the 
"parisc 1.1 IO firmware Architecture".
I didn't find it for parisc 2.0 (on 
http://www.parisc-linux.org/documentation/index.html). 
So if someone know where I can find it.

	Thanks.

The iodc.pdf document sez (page 3-29) 

ENTRY_INIT(index 3)
....
-9 Cannot locate a console device or boot device
   Returned only by options arg1=2 and arg1=3.


Dunno if it helps.

Please take a look to my email -> I'm using arg1=4 or 5
not 2 or 3. 
So how do you explain this -9 for "init & test mod & dev"

	Thanks.

I red :-) You mentioned 'parisc 1.1 IO firmware Architecture' which is kind of
generic title, then thought you missed the iodc.pdf doc.

> So how do you explain this -9 for "init & test mod & dev"

May be you used arg1 to 2 or 3 when you really wanted 4 or 5 

OR

-9 is also returned for 4 or 5 meaning  meaning
 1: machdep.h:283   #define IODCE_NOSUCHDEV  -9

as returned by scan from ./ISU/mongoose/machdep.h

Cheers,
Phi

	hi
Good news, now I'm able to initialise and read/write on
multiple disk. The solution a new time was a specific
PDC call on PAT system (we don't need it on 712 for example):

dump_pdc_call(PDC_IO, PDC_IO_RESET_DUMP_DEVS, __pa(pdc_result),__pa(dumpdev))

where dumpdev is the list of all "struct device_path".
It would be really interresting if someone is able to
find the "parisc 2.0 I/O firmware" doc, it would gain
a lot's of time to poor little programmers like me.

	Bye.

IIRC, this call is PAT PDC specific. The reason it was added is PAT PDC
only initializes boot and console devices. The RESET_DUMP_DEVs was added
to initialize a list of devices so IODC could be used in the HPUX
dump path.

Best is to scrounge through HPUX source code.
With docs, it's often difficult to know *where* to find the right info.
