[parisc-linux] Dump: need disk layout function.

[Bruno Vidal]

[-- Attachment #1: Type: text/plain, Size: 508 bytes --]

	Hi all.
I'm looking for function that manage disk layout. In fact I'm looking
for functions that are able to return start block and end block of
a partition. Do you know if it exists (I'm sure that it exists), and where it is ?
By the way, I'm looking for a function (or structure) that return the HPA 
and the SPA of a disk (but for this I find nothing, except for the boot 
disk in page0).

	Thanks.

Tried fs/partitions/msdos.c?

How can a disc have HPA and SPA?  Are you trying to find the HPA/SPA of
the disc's controller?

[parisc-linux] does audio works on 712,715 and 735?

[Jean-Louis Abat]

hi,

I ear that audio works with 735!
Does it work with 712 and 715??
I tried a few month ago on 712, but it didn't work... I didn't upgrade since
that time, from which kernel/packages versions could it work?

best regards

jl.

With 712 it works fine.
I've got a 712/60 and it works fine while playing MP3.

You need the harmony driver.
I think all Kernel > 2.4.17 do have this driver.

I thought the boot and dump devices have a faked HPA for IODC.
The code in palo/ipl/pdc_misc.c looks like it:

int
pdc_iodc_bootin(unsigned devaddr, char *memaddr, unsigned size)
{
    int r;

        r = firmware_call(PAGE0->mem_boot.iodc_io,
			PAGE0->mem_boot.hpa, ENTRY_IO_BOOTIN,
			PAGE0->mem_boot.spa, PAGE0->mem_boot.dp.layers,
			pdc_result, devaddr, memaddr, size, size);
....
