* Trouble with 2.6.16 on ppc8xx ?
From: David Jander @ 2006-04-14 8:50 UTC (permalink / raw)
To: linuxppc-embedded
Hi all,
I just cg-update'd to the HEAD of the denx 2.6.x kernel tree (2.6.16 as
released).
Our board-support stuff was succesfully moved along from 2.6.14 (when
everything but the SCC3 and SCC4 uarts worked just fine).
I compiled a kernel without any special drivers, just console on ttyCPM0, but
after "Uncompressing Kernel Image ... OK" there is no more output and no
further activity on ethernet (it should boot from nfs-root) or any other
device.
After "cg-seek DENX-v2.6.15; make clean uImage", it works again (everything
seems fine, system boots).
Our board is based on a MPC852T and until now we used "MPC86X" as the
BOARD_CHIP_NAME and it worked just fine with 2.6.14 and 2.6.15, but not with
2.6.16 as described above.
When doing "cg-diff" and carfully examining it's output, I can only see our
board-support stuff (not very much, not very special) and some custom drivers
that are disabled anyway.
Any clue about where to start looking?
I didn't find any suspicious changes in arch/ppc/mm, arch/ppc/syslib and
arch/ppc/kernel. Neither in drivers/serial/cpm_uart.
Which change from 2.6.15 to 2.6.16 could have broken 8xx support for us?
Is there perhaps a known issue with 2.6.16 and ppc8xx I am unaware of?
Greetings,

Who or what is the intended consumer of this information?
You should probably check get_property's return value and print the
partition_name line only if it is non-NULL.

I created the attached patch to print the partition name along with the
other partition information reported in /proc/ppc64/lparcfg for the
powerpc systems. The patch adds a single line of code to the
arch/powerpc/kernel/lparcfg.c file. I tested the code on a power5 box.
I would suggest adding the same line to the I series code at line 101 so
the partition name is printed on I series hardware as well. Since I
don't have access to I series hardware to test on I did not include this
change in my patch file.

We should make lmb_reserve() of redudant/overlapping entries become
harmless I think. We need to be backward compatible with earlier blobs
that do contain themselves in the reserve map

Darwin has the macros to access the TLB though it doesn't use them... I
suppose I can get the necessary doco bit from the microelectronics folks
for the CPC925, that should apply to U3 as well, though U4 has a
different format afaik. I'll dig and will come back to you.

Ok, that's what OS X does... I always wondered ...
So ideally, we should do something similar to the above and set some
global bit somewhere telling the exception path to change the return
address. In either case, the actual form of the loop becomes fairly
irrelevant.
I need to verify what's up with the 970. I noticed Apple has some
additional weird tricks involving setting the DEC to a short value but
setting POW without EE (though I don't remember for sure, I should dbl
check their code). I suppose I should ask some IBM folks there.
Ben.

What was keeping me from implementing this before was the lack of public
documentation on how to do it. Has that changed? I'd be happy to do the
implementation.

I would expect the dynamic predictor to work quite well on this. I'm not
worried about the overhead of the tests as much as the overhead of
having to enable the DART for smaller configs. If benchmark profiling
shows different down the road then we can add them.

I applied that fix on top of all the others and re-built and booted
a "generic" kernel (using arch/ia64/defconfig) and a "sparse" kernel
(based on arch/ia64/configs/gensparse_defconfig).
Both booted just fine on my tiger, the memory amounts looked
a bit suspicious though ... as if you are reporting *all* the
memory in range for the zone, rather than the usable parts.
Diffing console log from the boot of a 2.6.17-rc1 generic
kernel against one with your patches the relevent bit is:
< On node 0 totalpages: 259873
< DMA zone: 128931 pages, LIFO batch:7
< Normal zone: 130942 pages, LIFO batch:7
---
> On node 0 totalpages: 262144
> DMA zone: 131072 pages, LIFO batch:7
> Normal zone: 131072 pages, LIFO batch:7
That's a very precise 4G total, split exactly 2G+2G between
DMA and normal zones. Same thing for the sparse kernel
(though I didn't check what an unpatched kernel prints).
At the end I've put the console logs from a generic boot, a
generic boot with your patch, and finally a generic-sparse
boot with your patch.

So, it makes sense to me that this would work, but I suspect there
may be hardware wierdness - the user manual is very specific about
the code sequence that should be used (although I've given you a
slightly different sequence in my last mail that is also known to
work and is cleaner, IMHO). Let me check with one of our HW
designers to see if this is OK. It might be tomorrow before I have
an answer - it's after 4:30 here and some of them are early birds,
and might have already left for the day.
FYI, the user's manual recommends this sequence:
loop:
sync
mtmsr POW
isync
b loop

Ohhh ... we always assumed mtmsr with MSR_POW was
immediate/synchronous ! That explains a lot. The problem with the above
though is that we'll never get out unless we also hack the exception
path to change the return address once an exception happens. It's not
that difficult especially since we already have a special case to handle
returning from NAP there, on ppc32 at least. ppc64 will need a bit more
investigation.
Do you see another way to loop until NAP has gone ? Maybe reading msr in
a loop until POW gets cleared would do the trick ?

How so ? Anything remotely related to the iommu is totally different...
Besides, on x86-64, laptops _are_ more common, and thus the problem of
cardbus cards is much more significant.

PCI walking it soo late to decide wether to enable the DART no ? In any
case, we need a table, so I wouldn't bother with PCI walking here.
Anyway... we should be able to have almost no perf. degradation or even
an improvement with the DART thanks to virtual merging. Currently, we
pay a cost due to our stupid invalidate mecanism that we should really
fix by shooting the TLB directly. Also have you made sure all your
additions for handling crappy hardware are nicely wrapped in unlikely()
statements ? :)

Actually, I think the problem is that the code linux is using to turn
on nap mode is not guaranteed to put the processor in nap mode by the
time the blr in ppc6xx_idle occurs.
This is at the bottom of ppc6xx_idle:
mfmsr r7
ori r7,r7,MSR_EE
oris r7,r7,MSR_POW@h
sync
isync
mtmsr r7
isync
sync
blr
Unfortunately, NAP mode does not necessarily fully take effect for
some number of cycles after the mtmsr, and the sync isn't enough to
guarantee this. So it's entirely possible that you execute the blr
and carry on with the next function, which is local_irq_enable (or
perhaps a MSR read in the case of your test code) which is going see
the MSR value with POW set because you haven't started napping yet.
The above code should really look like this:
mfmsr r7
ori r7,r7,MSR_EE
oris r7,r7,MSR_POW@h
sync
isync
mtmsr r7
isync
label:
b label
blr

This wouldn't help - MSR[POW] is cleared on exception and is not a
bit that is saved in SRR1.
Hope this helps - I don't have hardware to test this on, so I can't
be sure, but it seems to explain the behavior you're seeing if I'm
understanding the problem correctly.

When you get around to it later, there is one case you may hit that Bob
Picco encountered and fixed for me. It's where a "new" range is registered
that is inside an existing area; e.g.
add_active_range: 0->10000
add_active_range: 9800->10000
It ends up merging incorrectly and you end up with one region from
9800-10000. The fix is below.

Yes, that boots. What's more the counts of pages in DMA/Normal
zone match the kernel w/o your patches too. So for tiger_defconfig
you've now exactly matched the old behaivour.
I'll try to test generic and sparse kernels later, but I have to
look at another issue now.

Cool! bonus points if you do it in drivers/pci and we can steal it
easily for Calgary on x8-64 :-)

Back to not booting with tiger_defconfig on Intel Tiger box :-(
There are no lines like:
On node 0 totalpages: 260725
DMA zone: 129700 pages, LIFO batch:7
Normal zone: 131025 pages, LIFO batch:7
in the log ... which might explain the OOM later.

From: Wade Farnsworth @ 2006-04-13 16:16 UTC (permalink / raw)
To: linuxppc-embedded
In-Reply-To: <1144194855.32471.64.camel@rhino.az.mvista.com>
From: Wade Farnsworth <wfarnsworth@mvista.com>
Adds support for the Freescale PQ2FADS board.
Signed-off-by: Wade Farnsworth <wfarnsworth@mvista.com>
---
This patch makes use of PHYLIB, and as such requires the following
patches from Vitaly Bordug <vbordug@ru.mvista.com>:
ppc32: Fix string comparing in platform_notify_map
PAL: Support of the fixed PHY
FS_ENET: use PAL for mii management
This supercedes the previous patch posted on April 4.

Walking the DT means we need to hardcode it on PCI IDs, since the Apple
OF doesn't give the Airport device a logical name. It's probably easier
to implement than walking PCI, but we'd need to maintain a table. My
vote is for PCI walking, I'll give that a shot over the weekend.

Yep, that should be rare enough.

It's something I thought about, but right now we enable the IOMMU quite
early during boot. It'd take a bit of surgery to shuffle things, and I
decided that it's not worth the work (and risk of regressions) for 2.6.17.

Supporting an old system for years is one thing. Adding new features
is a completely different beast. Looks like you have to spend some
substantial time, just to get something running. Are you sure this is
desired and preferred over a kernel upgrade? Might be worth
rethinking.
