No you're right that won't work, what I had in mind would work for
teardown, we could get the mpic from the chip_data of each virq.
But for setup we need to know which mpic to create the mapping on
_before_ it's mapped (obviously) so using chip_data doesn't work. And
yeah, guessing based on the legacy irq of the pci_dev would not be safe.
The only safe way to do it I think would be to walk up the interrupt
tree and find the interrupt controller node, then do an irq_find_host(),
but that's a lot of fuss to save one static variable :)
Patch looks good otherwise.
cheers

Surely you want "u32" or "freg" here?

You should probably reset __debugger_fault_handler, just to be safe.

This was the only function left in xmon/setjmp.S. So rather than rename
the whole file to reflect it no longer has anything to do with setjmp, I
moved it out to misc.S
I'm not fussed what we end up doing.

This stray down would cause a permanent sleep which doesn't seem correct.
The other uses of this semaphore appear fairly mutex like it's even initialized
with init_MUTEX() .. So here a patch for removing this one down().

I was following the bouncing ball here from the xmon code. We don't
want the hardware executing any of potentially dangerous hooks before
we've setup the setjmp save buffer. Similar, any code past the
dangerous hooks shouldn't be executed before we take a machine check.
It's definitely not a fast path so.... :-)
> At least comment why the delay is needed (and why just 200 is
> sufficient).
xmon.c says:
/* wait a little while to see if we get a machine check */
I'll update the "200" with a #define SETJMP_MACHINE_CHECK_DELAY and push
the same change into the xmon code. This delay in the machine check is
apparently required on 601 machines.
All you other comments I agree with.

In the hotplug code. So I guess it is not very relevant to you, but it
is a pain to retrofit this stuff if it does become important more widely.

I disagree. Why should we force bank A to stomp on bank B, if we can
prevent this in few lines of trivial code? It doesn't need any measuring
or simplifying IMO, what's so complexing in array of spinlocks guarding
array of banks?
But, you can repeat that you really want to get rid of this array --
and I'll silently remove it. Not because I gave up, but mostly because
with gpiolib we'll able to embed spinlock into per-bank gpio_chip
structure, thus eventually they will come back. :-))

No. This is how gpio api is working currently. With gpiolib[1], most of
these functions will be controller-specific. IIRC, gpiolib is still in
early development stage, so, for now, we have to limit us to one gpio
chip controller.
This works great for us: CPM, CPM2 and QE shouldn't appear on the single
crystal.
I'm not sure if gpiolib will hit 2.6.25, really. Maybe not. So I'd rather
stick with limited gpio api, and later convert it to gpiolib -- it will be
really trivial. Just rename functions and wrap them around gpio_chip
structure.
The bright side of smooth transition is that API itself isn't changing,
GPIO API/GPIOLIB API is fully interchangeable, their differences are

Depends on what your console is, but if it's something simple then you
should be able to write to it without taking interrupts.

This is the approach that I am currently taking with our future design.
In our system, we actually have 2 physical systems running Linux inside
the V4 (that's why there are 2 PowerPCs :) ). My current plan would be
to have the device trees stored in FLASH along w/ a single linux image.
Our bootloader on the board would then copy that information from FLASH
to RAM for both systems. This allows us to have two physically different
systems setup with different hardware, but have one linux image with two
different device trees. With a standard linux kernel weighing it at ~
3-5MB (including initramfs) that's a hefty savings in FLASH for us. Plus
it can considerably lower boot time instead of having to verify multiple
large images.
DL> In static or fairly static hardware, that's fine. Even in somewhat
dynamic hardware with large quantities of startup resources - like a PC.

starts to become an issue.
SN> As Grant says, the dynamic detection doesn't have to be done in the

I don't know if packaging the device tree with the bitstream is the best
way to go. It's possible that it could lead to headaches for certain
systems that have security restrictions. The same could be said for
using it w/ the SystemACE to load it into RAM after the image. (which is
what I'm currently doing for my 2 linux images in lieu of a true on-chip
bootloader). I am already taking the security concerns into account for
future revisions of the hardware wrt to using a SystemACE, and am
planning on moving the device trees into NV storage like FLASH.

I do agree that using more FPGA resources is not a solution to the
problem. I'm already hitting 80% usage on a FX60 and trying to squeeze
more real estate for storage of the device tree seems silly. Especially
since that would require that every image have this extra hardware built
into it just to support booting a Linux kernel. Why should I have to
have different hardware to boot linux, versus non-kernel, xilkernel, or
other (GHS, LynxOS, etc..)?

One solution I've been thinking through (in lieu of direct support from
EDK) is to use a tcl script with xps to traverse the hardware tree and
generate the device tree. It seems like it should be relatively trivial
to obtain the information. It's just going to be a pain to write all the
handlers for each different linux driver: temac, interrupt controller,
DMA controller, etc.
In reality the best way to handle this would be to have EDK generate the
device tree as part of the library/bsp build process. Now, what I'd like
to see with regards to this is the ability to change the handler for the
generating a specific device information. An example could be the temac.
If at some point in the future the temac needs new/more information to
support its configuration/run-time then having to get a patch from
Xilinx for a EDK is way too slow. The developers should be giving the
opportunity to inject a new handler into the various parts of the device
tree generation. That way when the kernel patch is submitted, an EDK
device generator patch will be submitted at the same time to keep
everything in sync.

The issue here is that the hardware changed and the driver doesn't
support it. I think this would be fixed by having information passed to
the driver in the platform_device struct to specify information, since
its not able to be discerned by the physical hardware information:
version registers, etc.

Hi Anton,
Apologies for not getting back sooner to comment...
We've been using a home-brewed UPM driver for our NAND for a while now.
There's several issues we've hit that I figured I would share. The
issues involve deficiencies of both the UPM and the NAND part itself.
We modeled our driver loosely after the suggestions in this white paper:
http://www.freescale.com/files/32bit/doc/white_paper/NANDFLASHWP.pdf?fpsp=1&WT_TYPE=WhitePapers&WT_VENDOR=FREESCALE&WT_FILE_FORMAT=pdf&WT_ASSET=Documentation
We also connected the NAND according to the suggestions in the above
document.
Something that you should be made aware of right away about the UPM -
you do not have control of the logic lines all of the time. You only
can control them during a transaction (in our case, a byte transaction).
In other words, the time that is between reading/writing bytes, or
putting the address on the bus, or asserting commands you are not able
to hold the lines to a certain state. Most of the control lines coming
from the UPM default to a logic 1 when unused (I believe only one
defaults to a logic 0).
The first issue is timings between versions of processors. We've got
one board using an MPC8349 running a 1Gb ST micro part (NAND01G-B).
Another board is an MPC8347 using the same 1Gb ST micro part. After
much time analyzing logic analyzer captures we found that write pulses
with the 8349 had to be shifted to the left a half clock in order to
properly latch the data on the bus. This was unexpected given the two
boards are very similar and the processors are in the same family. I
suppose the fix was easy enough, we just had to make a new version of
the microcode. What's interesting is that Freescale said that there's
nothing different between the two processors' UPMs. Yet there is a
distinct difference between local bus behavior on the 2 cpus, our LA
captures prove it.
The second issue was with interrupts during reads. We noticed that some
of our boards experienced ECC errors while reading the NAND. Logic
analyzer captures and debugging revealed that when an interrupt happened
while the driver's read code was executing, the UPM went into an idle
state, and the chip select of the part went high. This may not be a
problem for other NAND parts, but for our ST Micro parts, the spec says
that if CS is held high for more than 100us, the part will exit page
read mode. The default state of the UPM pins are high, so when the UPM
is idle all the signals are at logic 1.
Anyways, when the interrupt had completed, or driver wasn't aware that
an interrupt had occurred, so it continued to do it's read loop. The ST
Micro part was now in an undefined state. The page read appeared to
continue just fine, but we almost always had one or more bits corrupted
for the very first resuming data byte.
The fix that we ultimately did was to move the chip select control from
the UPM to a GPIO from the processor. This forced the chip to never
"sleep" during an interrupt, because we could keep the chip select low
for the entire page read transaction. This brought up other minor
issues. You must make sure that your boot loader (U-Boot in our case)
sets the GPIO data BEFORE it sets the GPIO direction. Otherwise the
NAND will automatically enter a start up read condition that will drive
the local bus, causing anything else on the local bus (such as a NOR
flash) to be useless...
The latest version of the app note online (link above) does not mention
the problem you may experience with interrupts. I requested from our
Freescale support contact that Freescale document this fact and make it
available to others such that they won't bump into the same problems we
did!
The THIRD issue we had (actually, are having) is very related to our
second issue. Our customer now wants a 2Gb NAND on our board. We
swapped the chip out. We included one more address byte transaction
that is needed with the larger part in the driver. And it doesn't work.
The part is considered to be the "bigger brother" to the 1Gb part, but
apparently enough of it's state machine has changed that it doesn't
tolerate the AL and CL lines going high while chip select is low.
Incidentally, when debugging our second issue we were told by ST Micro
support that the only time AL and CL were sampled by the NAND was when
W# and R# were driven low. Had we known that the 2Gb part wouldn't have
worked, we would have done much more major reworking to the NAND
subsystem when we respun our board.
This mail isn't meant to be a rant. Everyone knows that this kind of
low-level hardware/software work is difficult. This mail is meant to
caution you against using the NAND with the UPM. Freescale may say that
it works, and present you a pretty looking white paper, but it's really
kludgy and you are pretty guaranteed to have problems. Please encourage
your board designers to hook the NAND to some sort of CPLD device rather
than the UPM. At least with a CPLD you have some real control over the
state of the control lines.
If you for whatever reason are stuck with the UPM...
1.) Get your hardware people to stick inverters on the AL and CL lines.
Adjust your UPM microcode accordingly.
2.) Put your CS under control of a GPIO pin.
3.) Buy a nice logic analyzer, because you're going to need it!!!
I hope this helps someone out there... I've been spending a lot of time
on-and-off on this. Every time we think we have it right one little
seemingly benign change throws the whole thing out the window...
Okie, happy coding,
Chris Fester

* [PATCH 2/2] kdump shutdown hook support
From: Michael Neuling @ 2007-12-13 3:16 UTC (permalink / raw)
To: Paul Mackerras; +Cc: linuxppc-dev, Michael Neuling, RAISCH, THEMANN
In-Reply-To: <1197515777.834799.307108384755.qpush@coopers>
This adds hooks into the default_machine_crash_shutdown so drivers can
register a function to be run in the first kernel before we hand off
to the second kernel. This should only be used in exceptional
circumstances, like where the device can't be reset in the second
kernel alone (as is the case with eHEA). To emphasize this, the
number of handles allowed to be registered is currently #def to 1.
This uses the setjmp/longjmp code to call out to the registered hooks,
so any bogus exceptions we encounter will hopefully be recoverable.
Tested with bogus data and instruction exceptions.

* printf - How does it work?
From: Siva Prasad @ 2007-12-13 3:23 UTC (permalink / raw)
To: linuxppc-dev
[-- Attachment #1: Type: text/plain, Size: 385 bytes --]
Hi,
Can some one point me to an URL or some thing that explains how exactly
the characters from printf in user program gets printed on to the
console. Some thing like "it goes to /dev/console, and kernel reads from
....." would be great, so that I can trace it out.
Is there any way, we can get access to those prints from the kernel?
Thanks
Siva

* [PATCH] Convert adb.c to use kthread API and not spin on ADB requests
From: Paul Mackerras @ 2007-12-13 4:11 UTC (permalink / raw)
To: linuxppc-dev
This converts adb.c to use the kthread API.
It also changes adb_request so that if the ADBREQ_SYNC flag is
specified, we now sleep waiting for the request to finish using an
on-stack completion rather than spinning. To implement this, we now
require that if the ADBREQ_SYNC flag is set, the `done' parameter must
be NULL. All of the existing callers of adb_request that pass
ADBREQ_SYNC appear to be in process context and have done == NULL.
Doing this allows us to get rid of an awful hack in adb_request()
where we used to test whether the request was coming from the adb
probe task and use a completion if it was, and otherwise spin.
This also gets rid of a static request block that was used if the req
parameter to adb_request was NULL. None of the callers do that any
more, so the static request block is no longer necessary.
