Short update...

I will not post v4 until I can do a bit more testing.

Next week I get a SS1000E box (thanks to Chris <crn@netunix.com>) which
allows me to test the sun4d changes.

Huge thanks to Chris which has put a lot of effort in getting the
box operational again and for all the effort concerning the shipping!
I owe him more than one beer for this...

Kjetil mentioned he would try the genirq patches on his SS1000.
And I hope to get feedback from Gaisler too.

The patchset will likely not see testing on:
- Javastation (the pcic changes)
- sun4m with multiple CPUs
- sun4c

I have checked the nearby ebay's for relevant boxes - no luck.
On the other hand there is also a limit for the size of
my SUN museum :-)

Hi,

With regards to testing on sun4d, I have run into problems with the 
existing kernel, during the process of getting a test system up and 
running. The system is unable to mount partitions correctly, 
(both ext2 on a hdd, and iso8859 on a cdrom), however dd, running from an 
initrd filesystem is able to read the ext2 blocks correctly. So I have 
started investigating this instead. 

Is there anyone aware of any alignment requirements in the sun4d on DMA 
transfers and such ? Or have the datasheet for the FAS2x6 (236) scsi 
controllers ? 

Sorry for highjacking the thread a bit.

Regards,
Kjetil Oftedal

I have one of these, however it currently lacks any way to boot it.

If you could send me your tips for building tftpboot images and stuff,
it'd save me some time.

First check that you can see the drive correctly from the OBP
ok> probe-scsi-all

If that is OK try booting with no SMP, I forget the correct incantation
but something like "max-cpus=1" sounds familiar.

You could also try booting with a 2.2.x kernel, if that does not work
something is SERIOUSLY wrong. 2.2.x does not support SMP and has
always booted OK for me.

Do you have Solaris, it should boot and run 2.6, 7, or 8 (last supported).
If this fails you certainly have hardware issues.

Sorry to be vague, there has been no properly working Sun4d kernel
since 2.2.x so expect to find bitrot in all sorts of obscure places.

I've got a small "SUN museum" ...
sun4c: SPARCstation IPX
sun4m: SPARCstation5 (microSPARC II)
sun4m: SPARCstation20 (two-way superSPARC II)
sun4m: SPARCstation20 (four-way hyperSPARC Colorado-3)

Never got the IPX running on 2.6, but the others are spinning just
fine on some 2.6.1x UP (x=low).
I'm looking forward to give your patchset a try.

Best,
M

Great!

If you fetch sparc-next-2.6.git:

   git://git.kernel.org/pub/scm/linux/kernel/git/davem/sparc-next-2.6.git

then you only need to apply the patch from this mail:

    http://marc.info/?l=linux-sparc&m\x129823440700712&w=2

I'm looking forward for the result of the tests.

Hi,

The hyperSPARC gives the same error without the final genirq patch.

I realize that it may be a difficult proposition, but you could try to
git bisect it.

Did you try it on anything after 2.6.17, maybe that narrows it down further?

The userspace stuff I have is built with buildroot.
I used the attached configuration.

When building the kernel I use:

ROOTFS=/path/to/buildroot.git/output/images/rootfs.ext2
make ROOT_IMG=${ROOTFS} ARCH=sparc tftpboot.img

I then copy the final tftpboot.img to /var/lib/tftpboot/
as C0A800C8.SUN4M - this is the filename my sun4m box ask for.
I used tcpdump to check the name it requested.

I have rarp so my /etc/ethers define 
the relation between mac and IP like this:

08:00:20:05:38:d2       192.168.0.200


Initially my rarpd did not work.
I had to add following options:

# Do not check /tftpbootdir before response
OPTIONS="-v -e"

Until I realized this I uses

prom> boot net gateway-ip,,sun-ip

But it is much more convinient with rarp as I can then type "boot net".
And this is also default so I just turn on the box to boot it.

I was planning on doing that. Please be patient.

The C0A800C8.SUN4M string is generated based upon ip-address and 
architecture. The C0A800C8 is the IP address obtained by rarp translated to 
hex. (192 = C0. 168 = A8. 0 = 00. 200 = C8).

Cool, thanks - I haven't fiddled around with buildroot yet.

I'm all over tftpboot and rarp - I use tftp / rarp to install these boxes.

I'll have a go when I get home tonight, and hopefully have some sort
of result tomorrow.

You shouldn't have to go back that far...  I was last running 2.6.22 on
hyperSPARC successfully.  Ok, maybe that's not so helpful as it looks
like it's been a while since I've built a sparc kernel.  Probably time
for me to also try out a new kernel.

2.6.32 is fine too:
Linux ross 2.6.32.27-up #2 Sun Mar 6 23:05:25 CET 2011 sparc sun4m
ROSS HyperSparc RT625 or RT626 GNU/Linux

Today, I'll try to find out which commit causes the problems.

Hi,

git bisect came up with this:

4d14a459857bd151ecbd14bcd37b4628da00792b is the first bad commit

Author: David S. Miller <davem@davemloft.net>
Date:   Thu Dec 10 23:32:10 2009 -0800

Re: Status update on sparc32 genirq support [Was: sparc32: genirq

Hi Marcel.

Added davem...
We see strange SEGV faults in userspace and fail to read from ext2..
All on some (but not all) sparc32 boxes.

Great work!

Did you try a clean revert on said commit on top of sparc-next?
Just to confirm that this indeed the commit causing the bug -
and that reverting it fixes the bug.
Maybe you already planned to do so...

Looking at the commit I can see that it will require same hand-editing
to revert it. Obviously you can skip the parts that touches
sparc64 files.
On the way out of the door - so I cannot produce a patch
for you right away.
