[RFC PATCH 00/12] Merge common OpenFirmware device tree code

[RFC PATCH 00/12] Merge common OpenFirmware device tree code

[Grant Likely]

Well, I've got to start somewhere...

So here goes.  I've begun the work to merge and clean up the OF device
tree handling code and this is my first set of patches.  Not fully
tested yet, but I'm getting them out to the lists so that I can start
responding to comments and collecting acks.  This first batch isn't
anything exciting, just a merge of common code

[RFC PATCH 01/12] of: Rework linux/of.h and asm/prom.h include ordering

[Grant Likely]

In preparation to prune things out of the Sparc, PowerPC and Microblaze
asm/prom.h files, change the #include statements to ensure that
even if asm/prom.h is included first, linux/of.h gets to determine the
order in which files are processed.

This patch adds a #include <linux/of.h> to each of the prom.h files
*above* the multi-include protection macros to ensure that linux/of.h
can define things before prom.h gets processed.

At the end of the merge the cross dependencies between the files should
be gone and a sane #include scheme can be restored.

This is used in arch/microblaze/kernel/head.S, but you move its
definition inside "#ifndef __ASSEMBLY__" below.  You should probably
replace the include of asm/prom.h in arch/microblaze/kernel/head.S with
linux/of_fdt.h (assuming that the comment in there is correct).

yes, Stephen is right here. I created one patch (in attachment) which fixed it. I tested your
patches on Microblaze (noMMU and MMU) and I have no problem with compilation and simple boot-up
works for both versions too.

With that my patch: Acked-by: Michal Simek <monstr@monstr.eu>

Thanks,
Michal

P.S.: I have my provider - it block my emails - that's why the patch is in attachment.

yes, Stephen is right here. I created one patch (in attachment) which fixed it. I tested your
patches on Microblaze (noMMU and MMU) and I have no problem with compilation and simple boot-up
works for both versions too.

With that my patch: Acked-by: Michal Simek <monstr@monstr.eu>

Thanks,
Michal

P.S.: I have my provider - it block my emails - that's why the patch is in attachment.

I think you should prune the above. Make it (c) myself since I wrote the
FDT code initially. You can add back (c) of other people as you add more
stuff here I suppose.

No big deal tho.

No problem.  What is the exact copyright text that you'd like to see
here?  I'm not going to guess on other people's copyright notice.  :-)

So, if you're merging all these, I guess the question is do we also
want to merge them with scripts/dtc/libfdt/fdt.h, and by extension
with the upstream libfdt header file which defines the same things.

I see your question and raise you another.  Where should the merge
file live for it to be included both by dtc and kernel code? Or should
it just be cloned in the kernel tree?

Yeah, a good question.  As I see it there are two options.  Number one
is just make sure everything relevant that the kernel needs is in the
libfdt version, then just have the kernel code reference it from its
location in scripts/dtc.  Other option is we clone the file in the
kernel tree.  Requires keeping in sync, in theory at least, but since
that file has been pretty static (since it's only supposed to contain
passive structures/constants related to the physical flat tree
structure - no code or prototypes).

Merge common code between Sparc, PowerPC and Microblaze.

Sparc differs in the implementation at this point, so this patch uses
a #ifdef to handle sparc differently for now.  The merging of
implementations will occur in a later patch

a #ifdef to handle sparc differently for now.  The merging of
implementations will occur in a later patch

On the subject of merging code, I know that the SUN3 code in m68k uses
a similar prom interface to the sparc32 code. (and I've also
considered unifying that and ... well ... see above) Does anyone know
if it has an OpenFirmware interface for it's devices? Is OF on SUN3
even remotely useful? Does Linux on SUN3 even work with modern
kernels?

Another issue is that there is at least one driver in the kernel that
depends on both PPC and OF to work around the differences in the
implementations of OpenFirmware on Sparc and PowerPC. (I submitted a
patch for it, but can't remember the driver's name) Whilst the
driver's author assures me that the hardware will never go anywhere
near Sparc, it can't hurt to drop the dependency on PPC for additional
compile testing coverage - and because it's the Right Thing. (and the
reduction of cheap hacks like this can't be bad either.)

Other than that, good work, and keep going.

Thanks,

Sun3 doesn't have OF, though I've got some dormant patches to add an
OF emulation layer to make it easier to reuse Sparc drivers on
Sun3...   Never finished enough to submit, so it probably shouldn't
affect anything you're doing here.

As for recent kernels, I think 2.6.19 was the last sun3 I distributed
patches for, so modern might be pushing it...

Re: [RFC PATCH 00/12] Merge common OpenFirmware device tree code

[Mitch Bradley]

>
> Sun3 doesn't have OF

When I was first developing Open Boot for the SPARCstation-1, I was also 
simultaneously trying to do it for a Sun-3 system that was being built 
at the same time.

It proved to be too much to do both jobs at the same time, especially in 
light of all the hardware debugging that is part of a new system 
bringup.  So I gave up on Sun 3 and just focused on SS-1.

That particular Sun-3 machine never sold very well, while the SS-1 was 
very popular.  That was Sun's last 680x0 machine.

Personally, I think that continuing to support Sun-3 in Linux is not 
useful in a practical sense.  To the extent that supporting 
long-obsolete platforms and devices makes the job harder for current 
systems, it is actually harmful.  Portability and generality is good in

When I was first developing Open Boot for the SPARCstation-1, I was also 
simultaneously trying to do it for a Sun-3 system that was being built 
at the same time.

It proved to be too much to do both jobs at the same time, especially in 
light of all the hardware debugging that is part of a new system 
bringup.  So I gave up on Sun 3 and just focused on SS-1.

That particular Sun-3 machine never sold very well, while the SS-1 was 
very popular.  That was Sun's last 680x0 machine.

Personally, I think that continuing to support Sun-3 in Linux is not 
useful in a practical sense.  To the extent that supporting 
long-obsolete platforms and devices makes the job harder for current 
systems, it is actually harmful.  Portability and generality is good in 
some theoretical "rightness" sense, but there are practical limits.

Sun4c has also been broken for a long time and sun4d has never worked
properly. Is it time to also prune these ?.
That would leave only Sun4m in the 32bit kernel, which still works and
has plenty of ongoing user interest.

Chris don't over-exaggerate the state.

The truth is that the whole sparc32 port is in a state of mild
disrepair, and many of the issues apply to all the port rather than
just one family of systems.  I think someone suitably motivated
could get most of the bugs sorted out.

There is no reason to drop support for SS1 machines, we already fully
build the software device tree and use all of the generic OF
infrastructure in the Linux kernel on those systems.  It is not a road
block at all for the OF genericization work, if that's what you read
into wmb's email.

Your call, as you say there is little to be gained other than tidyness.

FWIW my opinions (and ICBW) are based on :-
Sun4c machines have a max of 48 or 64Mb and very few are still working
Sun4d has never had SMP support and this is apparantly problematic
  due to Cray interlectual property causing a lack of bus documentation.
  Running these heavy and power hungry lumps UP is a bit silly.

XBUS documentation is not available, but we fully know how to
program the SBUS interrupt controller and whatnot.  It's all
there in the sun4d interrupt and SMP support and it did work
just fine at one point.

Amusingly the SBUS interrupt stuff on sun4d is a very close
sibling to the IMAP/ICLR scheme used on sun4u.

The Sun4d SMP support exists, but is broken in 2.6.
And the UP support is buggy. At least on my test-setup, the
kernel is unable to load userland from scsi-drives.

Dropping the sun4 32-bit SPARC is a bit counterproductive when
considering the resent effort to unify sparc64 and sparc
arch-branches ?

I was also looking at using the OF code on m68k, but for a different
reason. My goal was to get macio_bus working so we can merge a few
of the m68k Mac drivers into the ppc Mac drivers. The simplest way
to do that seemed to be supporting OF since macio_dev is a wrapper
for of_device. It was also a nice way to build up a table of all the
onboard devices in memory. Hopefully it would enable better user-space
device detection as well.

I got the framework built against an older kernel, but it wasn't enough
to be useful at that point. This set of patches could help quite a bit.

Is there any news on getting QEMU to parse a device tree to figure out what 
hardware to emulate?  (I.E. using the device tree code to let qemu provide 
configurable board emulations instead of hardwiring them in C code?)

Also, what would be involved in getting x86 to (at least have the option to) 
use the device tree stuff?

Not that I have, but I expect that I will be hacking on QEMU as part
of this work.

It would be very easy once the endian issues are worked out since the
device tree is just a data format to be parsed.

I've got a few sun4u machines that are going strong.  I'd
hate to see support "go away" going forward.

I do wish I knew more about the archetecture and kernel development,
but alas, my life conspires against me when I try to learn more.

I do know that this release seems to be the latest version that I can cleanly
boot without much issue:

Linux wormhole 2.6.25-gentoo-r2 #2 SMP PREEMPT Tue May 6 20:59:30 AKDT 2008 sparc64 sun4u TI UltraSparc II (BlackBird) GNU/Linux

I do try to send bug reports/comments to the various lists, and watch the development.
Unfortunately, none of my systems are available for "lab" work, as they're all remotely deployed,
so testing of new kernels can really only happen when I have somebody available onsite
to remotely powercycle, as the crashes tend to be severe enough that I can't break-to-OBP

But thanks for all the hard work.

Leif

He's talking about 32-bit sparc machines made 15 to 20 years ago, not
sun4u boxes like your's.

Re: [RFC PATCH 00/12] Merge common OpenFirmware device tree code

[Mitch Bradley]

The Sun4 generations were (from memory):

sun4 - first generation SPARC, implemented as an FPGA.  IIRC, speeds 
topped out at about 20 MHz.  PCI bus.
sun4c - 2nd generation, implemented in CMOS.  SS1 and SS2 families.  
Desktop machines only.  Expansion via SBus. 40 to 80 MHz
sun4m - "SuperSPARC" - multiprocessor support.   TLB MMU
sun4d - "Sun Dragon".  Big iron, intended for high reliability.  Based 
on a bus architecture from Xerox PARC.
sun4u - UltraSPARC - 64-bit

There was also an ECL SPARC that never made it out of the lab.

This all looks OK to me.  One thing:  I started in this as well some time
ago and in my attempt I was hoping to avoid the ARCH ifdefs in linux/of.h
by creating asm/of.h and moving the differing bits in there ...

I'll send out the two patches I did just to show what I mean (these are
from before microblaze was using the OF stuff).

[PATCH 1/2] of: create asm/of.h

[Stephen Rothwell]

This creates asm/of.h for powerpc and sparc and includes it
from linux/of.h, it also moves the first trivial stuff there from
asm/prom.h

Thanks Stephen.

At the moment I'm purposefully experimenting with doing arch #ifdefs
in the hope that it will lead to obvious places where the code can be
generalized even further.  I'll see how it looks before I commit down
that path though.

In the mean time, I've pushed out the current series with acked-bys
added to my git server.  I think I'm ready for things to start going
into linux-next.  Since this is the first time I've asked for a tree
to be added to linux-next, please let me know if you see anything
troublesome or problematic.  Here's the tree:

Thanks Stephen.

At the moment I'm purposefully experimenting with doing arch #ifdefs
in the hope that it will lead to obvious places where the code can be
generalized even further.  I'll see how it looks before I commit down
that path though.

In the mean time, I've pushed out the current series with acked-bys
added to my git server.  I think I'm ready for things to start going
into linux-next.  Since this is the first time I've asked for a tree
to be added to linux-next, please let me know if you see anything
troublesome or problematic.  Here's the tree:

The following changes since commit 4bdf0bb7d64cf672199519b3d808e2a82f5b59e9:

Um, that commit is in no tree but yours ...

I have added this for today, but note that it contains stuff that is not
devicetree related.  Trees in linux-next should be based on other trees
in linux-next (almost always Linus' tree, but any other nonrebasing tree
is fine).

Thanks for adding your subsystem tree as a participant of linux-next.  As
you may know, this is not a judgment of your code.  The purpose of
linux-next is for integration testing and to lower the impact of
conflicts between subsystems in the next merge window. 

You will need to ensure that the patches/commits in your tree/series have
been:
     * submitted under GPL v2 (or later) and include the Contributor's
	Signed-off-by,
     * posted to the relevant mailing list,
     * reviewed by you (or another maintainer of your subsystem tree),
     * successfully unit tested, and 
     * destined for the current or next Linux merge window.

Basically, this should be just what you would send to Linus (or ask him
to fetch).  It is allowed to be rebased if you deem it necessary.

It should be in Ben's merge tree shortly, and Linus' shortly after
that, but yeah that was lazy.  It was the tree that I tested my
commits on, and I should have either rebased or waited until it
actually hit mainline.  I just wanted to get the ball rolling before
heading out the door for Japan.

[RFC PATCH 00/12] Merge common OpenFirmware device tree code

Well, I've got to start somewhere...

So here goes.  I've begun the work to merge and clean up the OF device
tree handling code and this is my first set of patches.  Not fully
tested yet, but I'm getting them out to the lists so that I can start
responding to comments and collecting acks.  This first batch isn't
anything exciting, just a merge of common code
