Paul,

You pulled the wrong version of the Kconfig patch for prep/chrp/ 
pmac.  There is a newer version that doesn't leave duplicated 'bool's  
in the Kconfig:

* PATCH powerpc: Revised merge asm-ppc*/hardirq.h
From: linuxppc @ 2005-09-19 14:32 UTC (permalink / raw)
  To: linuxppc-dev, linuxppc64-dev

This is a revised patch to merge asm-ppc*/hardirq.h.
It removes some unnecessary #includes, but then requires
the addition of #include <asm/irq.h> in PPC32's hw_irq.h
much like ppc64 already does.  Furthermore, several
unnecessary #includes were removed from some ppc32 boards
in order to break resulting bad #include cycles.

Builds pSeries_defconfig and all ppc32 platforms except
the already b0rken bseip.

Yes, that's what I thought. But Eugene mentioned, that he boots vmlinux 
without any boot-wrapper on the OpenBIOS targets (except Ebony probably). You 
would loose this possibility, if I add this wrapper and switch from OpenBIOS 
to U-Boot bd_info struct in the kernel.

Did I miss something here? How should I proceed?

Can you provide a little more details? The MTD / JFFS2 code  in  this
kernel  is  not too old, andwe use it in a couple of projects without
such problems.

Don't worry. We backported the MTD / JFFS2 code. See the  history  of
changes on our CVS or git server.

Note that log files may cause a lot of trouble  when  using  a  JFFS2
file  system. Youmay want to addd a buffering layer, like pramfs in a
dedicated RAM area (SRAM ideally).

I thought he was talking about booting a uImage, which from the 
perspective of not having the zImage wrapper around it, is like booting
a vmlinux.  He may referring to his own production firmware capabilities
too. I'll let him comment.

In any case, if you follow the model used on 44x where the board info
is the standard method of passing info into the kernel, then we'll be
alright. This means you have to add additional code in the
arch/ppc/boot/simple/openbios.c shim to generate some compatible board
info.

Bad phrasing on my part. What I meant was "U-Boot is different from 
OpenBIOS targets already, as with U-Boot we don't use any boot-wrapper 
like with OpenBIOS".

Sorry for confusion :).

Hi again,

Thanks for helping,

Ok, good you asked, because I am willing to debug the problem until I get to 
the point where it fails, but I will need help, because I am not at home in 
jffs2 source-code nor its CVS history.

Here are more details:

Kernel: Denx CVS from around july 2005 or something. AFAIK there are no 
further modifications other than BSP-specific stuff to the MTD code since 
that day, so I won't bother upgrading any further right now.

Hardware: MPC852T custom board with a 32Mbyte mirror-bit flash-chip (x16 bus)

Software: System based on ELDK-3.1.1. Intended flash-layout and use:
  rootfs     : 10Mb, ro, hardly ever changed
  app        : 6Mb, ro, changed on software-upgrade by replacing partition.
  log+config : 12Mb, rw

The log+config partition is extremely oversized, because we are aware of the 
inefficiency of jffs2 for such purposes, we have the available space and we 
want to stay out of trouble. Syslog writes to 4 log-files which are limited 
in size to 50..100kbyte each. Logs are then rotated and one rotated copy is 
kept. Maximum flash use is around 800kbyte for logs + 50kbyte for config 
data. On a 12Mbyte partition, that shouldn't get us into trouble AFAIK.

Unfortunately right now I don't have debug messages, because since I installed 
a kernel with debugging turned on in the jffs2 driver, the problem hasn't 
repeated. I am working on that.

What happened: System boots, all fs are mounted. The first app that writes 
something to the log-partition (in this case a config file that is 
overwritten) causes the GC thread for that partition to crash with a BUG() in 
line 139 of gc.c, and the application freezes forever. Since GC is dead, all 
further write-accesses to that partition also hang forever.

The problem seems to ocurr after a few times power-cycling the board. We never 
intended it to shut-down nicely, if it is at all ever shut-down, so it must 
be able to survive quite a few power-cycles without breaking.

After a few more power-cycles, the problem is gone again. Each time GC kicks 
in, it does something, but it crashes before finishing the job, so each time 
the numbers reported by the printk() in line 138 change, and eventually it 
work again.

My big question: Is it at all possible that gc.c comes to that BUG() in line 
139 because of anything other than a bug in jffs2-code?
I mean, if hardware really was a problem, then I should also get at least 
CRC-errors from jffs2, shouldn't I? IMHO at least, jffs2 should be robust 
enough to not crash on flash-errors, shouldn't it?

Also, I am pretty certain that the hardware is good.... but you never know...

I am having trouble finding the right history, but that could be due to the 
fact that I am not very good at CVS (we use subversion which is slightly 
different) ;-)
The logs of almost all files in fs/jffs2/ which I have say that the actual 
version corresponds to the CVS-snapshot of March 13, 2005, and that the 
previous version of April 2004 is broken.
Which files were modified _after_ March 13, 2005? 
(A hint to what command options or tools to use to browse cvs-logs more easily 
at this point is appreciated... I am using cervisia).

I know about the problems jffs2 has with logfiles and alikes. I am still 
thinking about what would be the most robust way of coping with this, and 
until now, oversized partitions with log-rotation on size seems to do the 
trick. I don't want to loose log-data on power-loss so I don't feel so 
comfortable with buffering much of it in RAM.

What's the trouble caused by log files when using a JFFS2? I'm not
aware of that. Any pointers to where I should look into are much
appreciated.

I saw that you had a problem with uncachedPages in gt64260_eth.c.
I'm having the same problem you describe.  Did you ever get this
resolved?

Thanks for any help

Are you 100% sure your system is stable and wihout any memory errors?
Never seen any other erros or crashes?

Yes, for example when your  SDRAM  initialization  is  broken  and/or
other memory corruption happens.

I don't think it's a flash error. If there is data  corruption,  then
it's more likely the SDRAM.

cvsps is really helpful, see http://www.cobite.com/cvsps/cvsps-2.1.tar.gz

Also there are web interfaces to our kernel tree;
for CVS see
	http://81.169.171.120/cgi-bin/cvsweb/
for git see
	http://81.169.171.120/cgi-bin/gitweb.cgi

Make sure to use at least the version tagged as LABEL_2005_05_09_1245
or later.

The problem with your approach is the number of  erase  cycles  which
will cause the flash to die sooner than you may want.

I guess this should become a FAQ item.

JFFS2 creates one or more nodes whenever sys_write is called.
Unbuffered log entries are usually quite small, so a single node is
written.  Let's assume the worst case, just for fun, writes of a
single by.

Now, each node is prepended by a struct jffs2_raw_inode of 64 bytes.
So you're causing the first problem:
1. Up to 65x the raw file data is written to flash.

Which means you waste bus bandwidth, was flash space and waste flash
lifetime.  After GC, most of those nodes should get combined to 4k
nodes (plus 64 bytes for the header).  Now, JFFS2 also requires an
in-memory structure per node, the struct jffs2_raw_node_ref, weighing
in at 16 or 24 bytes, if you have a 32bit or 64bit arch.  Those will
cost you precious memory:
2. Up to 24x the raw file data is required in DRAM.

Next problem is with GC accounting.  JFFS2 only differentiates between
valid and obsolete data.  After writing a huge logfile, all of its
nodes are still valid.  Therefore GC will never try to GC such nodes,
unless they happen to sit in an erase block with a lot of obsolete
data.  And even then, they could get copied as-is, with no combining.
3. JFFS2 GC is too stupid to detect miniature nodes and combine them.

So, your problem 1 and 2 will not go away if you wait long enough.
Renaming the log file also won't help.  The only cure would be to
*copy* it to the new location and delete the original file afterwards.
Or - alternatively - to fix JFFS2 GC and send a patch.
Or - as already proposed - by writing in larger chunks in the first
place.

If you decide to fix JFFS2 GC, I'd be happy to review the patches and
merge them if deemed worthy.

Please see the linux-mtd web site and/or MTD  mailing  list  archives
for  details.  JFFS2 works excellent with files that are written once
(or with only a few write() calls. Logfiles typically  grow  forever,
by  many,  many  small  chunks  of  data  appended  in  many  write()
operations - this is kind of killer application for JFFS2.

* PATCH powerpc Merge atomic.h
From: Jon Loeliger @ 2005-09-19 20:29 UTC (permalink / raw)
  To: linuxppc-dev, linuxppc64-dev

Paul,

There is also Arnd's patch called "[PATCH 0/3] Start the merge"
from 08/29 that is really the merger of asm-ppc*/atomic.h.

I repost it here for Arnd, who can NAK it or not.

It is a pre-requisite patch for doing the rwsem.h merge
as discussed recently.

jdl



This is another patch to merge the atomic.h file. It is not completely
trivial and changes the semantics for 32 bit SMP systems, which previously
did not do EIEIO_ON_SMP within the atomic operations. AFAICT, that was
a bug in the 32 bit version, which is now fixed as a side-effect of
the merge.

The combined version of this file also prevents building user space
applications using atomic.h on ppc64. That was already impossible
on 32 bit ppc, but probably also created broken output on ppc64.

Signed-off-by: Arnd Bergmann <arnd@arndb.de>

Arrrg!  Scurvey dogs!  Ye cannt even squeek by repostin' old

Someone needs a floggin' til this applies properly.  Memory.h be damned.

* [PATCH] powerpc Merge bug.h
From: Becky Bruce @ 2005-09-19 22:01 UTC (permalink / raw)
  To: linuxppc64-dev, linuxppc-dev

Resending per Paul's request.....

ppc32/ppc64: Merge bug.h into include/asm-powerpc

This patch merges bug.h into include/asm-powerpc.  Changed the data
structure for bug_entry such that line is always an int on both 32 and
64-bit platforms; removed casts to int from the 64-bit trap code to
reflect this.

Avast, Cap'n Paul!

Did ye wan ta add Pantelis Antoniou's patch ta
support OF Flat Dev Tree to the powerpc-merge tree?
His patch be dated Sep-03, but I don't think I'll
be directly repostin' that booty here.
