Hi,
	Using the CVS kernel on a C100 I'm seeing it die with an out-of-mapping
resources error from ccio-dma.c. It looks like there's been some active 
development there about a week ago, but it's not helping my machine. The 
quickest way for me to bring it about is to try and use mke2fs, but just
mounting the CD and running a few commands will oftentimes do the trick.

How can I help debug this? There's really no useful information provided by
the printk now - is there some sort of debugging info I could be collecting,
or would a backtrace help?

Thanks

-Erik

Erik,

I also have that problem on the C200+, but it isn't a ccio-dma.c problem
(atleast I don't think it is) ... I believe it is a sym53cxx driver problem.  I
have already started tracking this down, and hopefully will have time to
find and squash the bug this weekend.

hope this helps!

Ryan

Ryan,
Here's the output from me (accidentally) booting a 32-bit kernel
on a c3k. It seems sym53c8xx passed a non-kernel address to get mapped...
or the ASSERT statement is bogus (checking too many bits).
Anyway, something to look at.

Bogus ASSERT. This c3k has more than 256M of memory and thus
some of the bits can be valid...fixing.

Erik & Grant,

I think I have finally tracked this problem down... I don't think it is a bug
in either the ccio-dma or the sym53c8xx driver.... I believe it is a sizing
issue with the IO PDIR in the ccio-dma.  I spent some time last week
increasing the density of the IO PDIR by 4x ... it looks like I still have some
work to do :)

I increased the the IO PDIR ratio to main memory by 4x and I can
successfully format a 4G partition in my C200+.  (When I bumped
the IO PDIR ratio by 2x, is still had problems...)

Erik ... I've attached a small patch for you to try and see if it works for
you.

Thanks,

- Ryan

Erik & Grant,

I isolated the problem, and have checked in an updated ccio-dma driver
that should take care of this problem for you Erik.  The problem was with
the way the ccio-dma handled the scatter/gather lists.

The sym53c8xx driver asked the ccio-dma driver to map 2 maps of
64 - 1024k dma entries.  The ccio-dma driver would map an entire
block (8 pages) for each of the 128 1024k dma entries.  I have checked
in a new ccio-dma driver that handles the scatter/gather lists much
more intelligently.  With these changes I map the entire 128 - 1024k
dma entries into 3 blocks (32 pages).

Erik:  When you get a chance, would you try out the new ccio-dma
driver and see if that fixed your problem.  (I'm betting it will).

Grant: Would you mind reviewing the changes I made to make sure
I didn't do anything stupid :)  I also made several bug fixes that
should/could be ported to the sba driver as well.

There are still some problems with this driver I'm working on tracking
down...  If the pdir is really small (32 MB main memory) ... I get a
HPMC.  But it seems to work when memory is larger (ie 128 MB main
memory).

Thanks and good luck!

- Ryan
