[parisc-linux] So you wanna get to a prompt, eh?

[Christopher Beard]

I've spent most of the afternoon working on the patches sent in by Thomas
Bogendoerfer, and have extended them to get the kernel working and to a
functional sash prompt. 

Instead of waiting on prumpf and others to finish commiting their code
(which I'm told conflicts with these changes), and not wanting to scramble
the CVS,  I'm going to post a tarball of my kernel tree at:

ftp://puffin.external.hp.com/pub/parisc/src/parisc-linux-src-19991019.tar.gz

And for those you out there who are interested in helping us test the
kernel, I've also posted a functional kernel image, for you try. You can
find it at:

ftp://puffin.external.hp.com/pub/parisc/binaries/kernels/Image-19991019-workingsash

And not wanted to leave much as an excercise for the reader, I've also
posted the ramdisk that I used, which has been extended to include
/dev/console, etc.

See http://www.thepuffingroup.com/parisc/recipe.html for Grant Grundler's
recipe, which includes a section on how to boot you PA-RISC box with one of
our kernel images.

Is the ramdisk included in the kernel-image? When I boot the kernel,
I get 'no ramdisk'.

Of course, I don't get further than 'Transferring control to kernel'..
:(
I thought I had a 715, but no, it was a 710 (Bushmaster), and that seems
to make a big difference.

Is anyone working on support for the 700?  I could do some work there,
if it was possible to compile the kernel on linux.  Is anything being
done on that? (What was the problem?)

The Image-990705 kernel worked. What changed from that to Image-990929?

To build the kernel right now, you have to download a ramdisk from
ftp://puffin.external.hp.com/pub/parisc/binaries/ramdisks or similiar.

I had that problem with my 715 too, but there was an alignment mistake
that I made that Philipp fixed yesterday.  You might want to update your
tree and build it again.

The 700 has an ancient IO architecture that we don't have any
documentation on, so it's not high on the list of priorities.  However, if
someone has patches to support it, we'd be happy to apply them.

As for cross compiling... we're forced to use HPUX because we don't have a
reasonable and functioning cross linker.  More on that later.

You don't need the ramdisk if you are booting from a binary image, you only
need it if you are attempting to build your own from the source tarball
that was posted. The confusion exists in that the bootloader currently
reports:

	Loading PA-RISC/Linux Kernel...
	No ramdisks available.

And then continues along with the boot process.

Support for ramdisks was built into the bootloader, which is likely the
prefered method, however, it has never been used. It is safe to ignore this
for now.

Yes, this is correct. I once wrote support for ramdisks loaded by the
bootloader, but this possiblility was never used until now.
If there is interrest for this, then it should be really easy to implement...
More, this method is much faster than the current method to convert
ramdisk.bin to ramdisk.c and then compile & link it statically into the kernel.

BTW: I will comment out this messages in my next commit. to not get more
confusion on this point !

But it is possible to get the docs from HP?

Is it possible to compile with linux, and do only the linking on the hp?
(It isn't very fast.. :)  Can I link with HPUX 9.03? (probably not)
10.30? (It doesn't run 11.x)

Yes. If HP can find them and verify it doesn't contain someone else's
Intellectual Property (which isn't published already).
HP sees releasing old docs as a low priority since it doesn't
generate revenue. IMHO, the only way this is going to happen is
if some HP person does this in their spare time and then gets the
right signatures/approval.

I've done some of this but don't care about boxes older than 715's
or servers older than K or D class.

This sounds possible but doesn't seem reasonable.

Use 10.20. It should run on your 710. Don't use 10.30 as it was never
intended for distribution on workstations and certainly doesn't have
the support which WSY has poured into 10.20.

I won't describe the woes I have had upgrading my 735 to 10.20
but I have had all kinds of problems with disk timeouts and unrecoverable
LPMCs with 10.20 on my 735.  These problems are only now getting
worked out of 10.20 (see recent patches to wsio driver, etc).
My 735 has about a dozen scsi devices on threee buses, so it
seriously stresses the IO architecture.

The machine ran for years under 9.01 with experiencing any problems
of this kind.

I can't speak for HP on this, but I will say that the old IO docs will
only be in the queue of requested items from HP once we've gotten some of
the others out.  We need to prioritize the docs we need, and the stuff
that's in more modern machines (even the 715) is much higher on the lsit.

That should work.

That should work, in theory.  I'm not sure anyone's ever tried though.

the cvs version from friday did only work on the A-class for me. My 715/33
panic very early in the boot process. I only did a quick look and I guess
it's caused by the serial console changes. I've no idea whether this is 
already fixed.
