This series lays down the ground work for changing the way we handle the
reset (now called restart) handling on ARM.
As a result of these patches, we provide a new hook in the machine_desc
record called 'restart' which is pointed at a function to perform the
appropriate restart actions for the platform. This is called directly
from machine_restart() with IRQs and caches on.
The 'soft_reboot' flag is changed to a more generic 'restart_mode'
character - which is used to initialize the default reboot mode (which
can be changed via the 'reboot=' command line parameter.)
'soft_restart(addr)' is added which performs a soft restart (iow,
orderly shutdown of caches and MMU and a jump to the passed address),
rather than the old way which separated the tear-down of the caches
and MMU from the code doing the jump. This will be necessary to
resolve the ARMv6 and ARMv7 CPU restarting problems.
Finally, appropriate 'restart_mode' values are added to several
platforms which were hard-coding the restart mode by intercepting
the restarting via arm_pm_restart.

Add a restart hook to the machine_desc record so we don't have to
populate all platforms with init_early methods to initialize the
arm_pm_restart function pointer.

Move the failure to reboot into machine_restart() to always catch
this condition, even if a platform decides to hook the restarting
via arm_pm_restart().

We only need to set the system up for a soft-restart if we're going to
be doing a soft-restart. Provide a new function (soft_restart()) which
does the setup and final call for this, and make platforms use it.
Eliminate the call to setup_restart() from the default handler.
This means that platforms arch_reset() function is no longer called with
the page tables prepared for a soft-restart, and caches will still be
enabled.

IRQs are already disabled by the time arch_reset() is called, so these
calls to local_irq_disable() instead arch_reset() are redundant. Remove
them.

From: Russell King - ARM Linux @ 2011-11-06 17:39 UTC (permalink / raw)
To: linux-arm-kernel
Part 2. These are the platform updates, so far.
The first patch combines the individual files in mach-clps711x which
contain one or two functions or data structures before changing the
arch_reset stuff.
The majority of the remaining patches address each group of platforms
individually.
The final patch removes the resulting empty arch_reset() functions,
its call site and associated code. XXX NOTE XXX This results in
anything left with an arch_reset() function having non-functional
restart capability.

From: Russell King - ARM Linux @ 2011-11-06 17:40 UTC (permalink / raw)
To: linux-arm-kernel
The separate files for clps711x which contain maybe one or two data
structures or functions is an inefficient use of files, and encourages
further small files as other changes happen. Collapse down these into
a single core.c file.

The poodle restart handler was added in 74617fb6b8 (3593/1: Add reboot
and shutdown handlers for Zaurus handhelds), and at that time it was
necessary to deal with the RCSR register. This commit also forced all
restarts to use the 'hard' restart method.
In dc38e2ad53 (pxa: Fix RCSR handling), the RCSR handling was removed,
leaving just the forcing to use a 'hard' restart. As hard restarts are
the default (in the absense of a reboot= command line argument), this
seems pointless. In any case, Richard Purdie says:
> From what I remember that hardware either always reboots or always
> halts. I think the option was therefore left hardcoded to make it clear
> it wasn't expected to work. Later Zaurii models could do either but
> required some manual poking of registers to make it happen iirc.

> Regardless, you can probably clean this up as you suggest now.
So, lets remove the unnecessary interception and rely on the default
restart mode.

Remove the s3c24xx restart handler, which is trying to work around
a chip bug by keeping caches on but flushed. As we now only disable
caches when performing a soft reboot, there doesn't need to be a
work-around to do that.

Rather than using a private function pointer, use the existing
arm_pm_restart function pointer instead. We no longer need to enable
the I-cache in at91sam9_alt_reset() as the caches will now be on when
this function is called.
Update the function names to use the 'restart' terminology rather than
the 'reboot' terminology.

than using arch_reset().
In doing so, we split out the n2100 platform specific restart handler
into the n2100 platform file.

In doing so, we split out the IXDP2401, IXDP2801 and IXDP2805 platform

Hook these platforms restart code into the new restart hook rather
than using arch_reset().
In doing so, we split out the ixdp2351 restart code into its own
platform file.

Hook these platforms restart code into the new restart hook rather than
using arch_reset().
In addition, convert calls to arm_machine_restart() to orion5x_restart()
to ensure that they continue to work as intended.

Hook these platforms restart code into the new restart hook rather
than using arch_reset().

Remove the:
KERN_CRIT "RESET: Rebooting system\n" (lpc32xx)
KERN_CRIT "RESET: shutting down/rebooting system\n" (u300)
printk from the restart handler; we already print such a message from
kernel_restart() in kernel/sys.c:
KERN_EMERG "Restarting system.\n"
so this is unnecessary.

arch_reset() is deprecated; systems should hook into system restart via
the 'restart' method in the platforms machine description record.

Remove the now empty arch_reset() from all the mach/system.h includes,
and remove its callsite. Remove arm_machine_restart() as this function
no longer does anything useful.

Part 3 - the remaining stuff
These are patches which I've managed to get half way through before
getting - to be honest - totally hacked off with the code found in
various platforms (as mentioned in previous mails).
These platforms are broken as a result of the final patch in part 2,
and these patches move these platforms _towards_ a solution. They
are not a complete solution though, but the start of the solution.
For instance, the Exynos4 and S5PV210 patches both consist of almost
a full solution -but- with the new function prototype missing because
there is _no_ local header file to put it in, and I'm damned well not
putting it in the remote plat-samsung/include/plat headers.
The final set of platforms - touched neither by part 3 nor 4, are
broken by the final patch in part 2, and at present I have no plans
to fix them. I would welcome patches to fix these which address the
issues raised in the "pet peaves" email (which is why I have no plans
to fix them.)

I notice in last nights merge of the Samsung stuff, this has become
less trivial - it's now:
/* set sw_reset function */
if (soc_is_exynos4210() || soc_is_exynos4212() || soc_is_exynos4412())
s5p_reset_hook = exynos4_sw_reset;
So which of the boards should be converted and which shouldn't ?
In other words, which exynos4210, 4212 or 4412 platforms?

except the arch/arm/mach-exynos4/mach-smdk4x12.c, exynos4210 is used.
currently all exynos4 series has same reset function. it's preparation
for exynos5 series maybe.
you can use the exynos4_sw_reset for all boards.
Thank you,

Thanks, that gets me back to where I was with the patch before the

I was dreading the thought of having to go digging around in each platform
again, so thanks for doing this. Apart from the troublesome platforms
(partially addressed in your third series), is there anything else that
needs looking at?
I guess I should also ask whether or not the third series is a blocker for
merging the other two (given that it would leave those platforms broken).
Cheers,
Will

In direct connection with this - that said, although I've build-tested a
number of these (which is why I found things like the trailing , on the
previous initializers - and had to rework some of the patches as a result),
I've also boot tested the Versatile Express and OMAP3 but not tried a
'reboot' on them yet.
The final removal of mach/system.h depends on getting rid of the arch_idle
thing. While going through these headers, I was dismayed to find these:
arch/arm/mach-s3c2410/include/mach/system.h:void (*s3c24xx_idle)(void);
arch/arm/plat-mxc/include/mach/system.h:extern void (*imx_idle)(void);
when we have a perfectly good pm_idle hook already in place - so there's
no excuse for these especially when other platforms are already using
pm_idle to hook their platform specific idle function into. This is
something that better be gone at the next merge window!

That depends on your point of view.
My original plan was to see about merging the ground-work (part 1) in
this merge window to avoid a dependency problem - but I think it grew
too large to contemplate that (I might have a discussion with Linus
in private over this, because not doing this could be quite hairy for
us.)
Part 2 is fine up until the final patch - if we can get part 1 in, then
the individual patches can be carried in the various maintainer trees
independently. In any case, patch 41 would have to be scheduled for
the end of the merge window.
As for whether patch 41 goes in with or without the remainder fixed up,
that depends what kind of a mood I'm in - over the weekend I was feeling
very pissed off with the state of the remaining platforms that I was
seriously thinking that I'd push it in anyway at the next merge window
and to hell with them. (Just like the Greece holding the eurozone to
ransom, I don't want a few platforms holding the rest of the ARM tree
to ransom over this change!)
I've moderated a little bit over that - but only to the extent that
there's going to be something like 12 weeks for other platforms to get
their act together and if they don't show willing to address the
concerns, then I'm really not going to care about breaking them at
the next merge window.

This one doesn't compile - cpu.h isn't included by the *evb.c files.
What's more... this isn't nice:
arch/arm/mach-w90x900/nuc960.h:extern void nuc900_init_irq(void);
arch/arm/mach-w90x900/nuc910.h:extern void nuc900_init_irq(void);
arch/arm/mach-w90x900/nuc950.h:extern void nuc900_init_irq(void);
arch/arm/mach-w90x900/nuc910.h:extern struct sys_timer nuc900_timer;
arch/arm/mach-w90x900/nuc950.h:extern struct sys_timer nuc900_timer;
arch/arm/mach-w90x900/nuc960.h:extern struct sys_timer nuc900_timer;
It's wanting a common nuc9xx.h header containing the common stuff,
which'll include the nuc900_restart() function prototype.
So, I'm punting this into part 3 of the patchset until it's fixed.

Russell,
You already have my Acked-by for the ep93xx part of patch 7.
But, FWIW, the rest of this series also looks good to me.

I saw those too and intended to get rid of those pointers.
I was just waiting for your arch_reset work to settle down before
respinning my arch-idle series.

I'd recommend publishing all those patches in your tree and pushing them
all in the next merge window. The probability for conflicts with
subarch trees is still relatively low. If conflicts are unavoidable then
using your branch as a base would be the way to go. Whether platform
code is then based on 3.2-rc1 or a particular branch in your tree is not
much different at that point.

I agree with that. However, if you merge those patches (including patch
41) in your tree now, that means people have about 5 months before this
change will show up in a released kernel, which should give plenty of
time for interested parties to fix their problematic code. The sooner
this appears in linux-next the better.

Exactly.

Russell,
The new restart prototype for s5pv210 and exynos can be placed in their
respective<mach/system.h>file. And the board files can include it. Would
this place be fine for the new prototype?
Thanks.
Best regards,
Kgene.

No - mach/system.h will be removed once arch_idle is gone as well. In
any case, this should not be in a mach/*.h file. There should be a
header in the arch/arm/mach-* directory for functions and data structures
local _only_ to the files in that directory.
Please read my 'pet peaves' email, point 4.

I'm not going to accept that for a patch which will cause a build error.
The purpose of throwing this set of patches out is not to get acks, but
to get people to think about the code that they already have in the
tree which is making the task of others unnecessarily more difficult
because of the way it is structured.
Let me repeat: anything in the list below _will_ be broken by this
patch series:
arch/arm/mach-bcmring/include/mach/system.h
arch/arm/mach-davinci/include/mach/system.h
arch/arm/mach-gemini/include/mach/system.h
arch/arm/mach-ks8695/include/mach/system.h
arch/arm/mach-netx/include/mach/system.h
arch/arm/mach-nomadik/include/mach/system.h
arch/arm/mach-omap1/include/mach/system.h
arch/arm/mach-omap2/include/mach/system.h
arch/arm/mach-s3c2410/include/mach/system-reset.h
arch/arm/mach-s3c64xx/include/mach/system.h
arch/arm/mach-shmobile/include/mach/system.h
arch/arm/mach-vt8500/include/mach/system.h
arch/arm/plat-samsung/include/plat/system-reset.h
arch/arm/plat-tcc/include/mach/system.h
and this includes *all* of the Samsung s3* and s5* stuff. Exynos4 at
least avoids it because all platforms there use the exynos4_restart()
function.
Also note: it's likely that some platform maintainers *will* want to
base their code off this series. People submitting new platforms will
want at least part 1 of the series so they can use the new feature.
So we owe it to them (and yourselves) to get the remaining problems
resolved as soon as possible so that the entire series is sound. So,
don't think there's three months to work on this.

I'm assuming that means just for

Okay, I agree. So how about mach-xxx/common.h for it?
If required, I will sort out all of Samsung stuff as per your suggestion.

Okay, I see.

I guess we want the rest of the board files to set .restart
to omap1_restart or omap_prcm_restart? Do you already have
some script doing that or do you need some help there?

It's fairly easy to do using my editor and grep to find the files needing
editing. As you'll notice from the previous message, I've already fixed
this up.
It passes both my OMAP3 and OMAP4 build checks, but I've not yet booted
the results.

I have to point out that even so, this patch as it stands will break
the exynos build (that's why the subject line contains the XXX WIP XXX
stuff.)
As I said in my pet peaves mail, there should be a header in
arch/arm/mach-exynos for the data and function declarations which are
only used by and only provided by files in this directory. Such things
as:
struct sys_timer exynos4_timer;
void exynos4_init_irq(void);
etc. This stuff should not be inappropriately placed:
arch/arm/plat-samsung/include/plat/exynos4.h:extern struct sys_timer exynos4_timer;
arch/arm/plat-samsung/include/plat/exynos4.h:extern void exynos4_init_irq(void);
(e.g.,
$ grep exynos4_init_irq\\\> arch/arm -r
arch/arm/mach-exynos/mach-nuri.c: .init_irq = exynos4_init_irq,
arch/arm/mach-exynos/mach-origen.c: .init_irq = exynos4_init_irq,
arch/arm/mach-exynos/mach-armlex4210.c: .init_irq = exynos4_init_irq,
arch/arm/mach-exynos/mach-smdkv310.c: .init_irq = exynos4_init_irq,

arch/arm/mach-exynos/cpu.c:void __init exynos4_init_irq(void)

arch/arm/plat-samsung/include/plat/exynos4.h:extern void exynos4_init_irq(void);
$ grep exynos4_timer arch/arm -r
arch/arm/mach-exynos/mach-nuri.c: .timer = &exynos4_timer,
arch/arm/mach-exynos/mach-origen.c: .timer = &exynos4_timer,
arch/arm/mach-exynos/mach-armlex4210.c: .timer = &exynos4_timer,
arch/arm/mach-exynos/mach-smdkv310.c: .timer = &exynos4_timer,
arch/arm/mach-exynos/mach-smdkv310.c: .timer = &exynos4_timer,
arch/arm/mach-exynos/mach-smdk4x12.c: .timer = &exynos4_timer,

arch/arm/mach-exynos/mach-universal_c210.c: .timer = &exynos4_timer,
arch/arm/plat-samsung/include/plat/exynos4.h:extern struct sys_timer exynos4_timer;
$ grep exynos4_register_clocks arch/arm -r
arch/arm/mach-exynos/clock.c:void __init exynos4_register_clocks(void)
arch/arm/mach-exynos/cpu.c: exynos4_register_clocks();
arch/arm/plat-samsung/include/plat/exynos4.h:extern void exynos4_register_clock(void);
$ grep exynos421._register_clocks arch/arm -r
arch/arm/mach-exynos/clock-exynos4212.c:void __init exynos4212_register_clocks(void)
arch/arm/mach-exynos/cpu.c: exynos4210_register_clocks();
arch/arm/mach-exynos/cpu.c: exynos4212_register_clocks();
arch/arm/mach-exynos/clock-exynos4210.c:void __init exynos4210_register_clocks(void)
arch/arm/plat-samsung/include/plat/exynos4.h:extern void exynos4210_register_clocks(void);
arch/arm/plat-samsung/include/plat/exynos4.h:extern void exynos4212_register_clocks(void);
)
I suspect a sizeable proportion of plat/exynos4.h could move into
arch/arm/mach-exynos.

The list of platforms which are still broken (today) by part 2 of this
series are:
arch/arm/mach-davinci/include/mach/system.h
arch/arm/mach-gemini/include/mach/system.h
arch/arm/mach-nomadik/include/mach/system.h
arch/arm/mach-s3c2410/include/mach/system-reset.h
arch/arm/mach-s3c64xx/include/mach/system.h
arch/arm/mach-shmobile/include/mach/system.h
arch/arm/mach-vt8500/include/mach/system.h
arch/arm/plat-samsung/include/plat/system-reset.h
arch/arm/plat-tcc/include/mach/system.h
which require assistance to get these into shape.
As I've already implied, I'm quite prepared to break these platforms at
the next merge window for the greater good if there's no sign of
maintainers willing to help sort them out - which will then ultimately
result in them being deleted from mainline.

Thanks. Could you look at what's required for Nomadik please? I couldn't
see am obvious file to move the arch_reset code from mach/system.h into,
nor could I see a local header file to put the new prototype into.

Rubini is the master of Nomadik, but I would put that into
mach-nomadik/cpu-8815.c.
As for header the functions in cpu-8815.c are broadcast
in mach-nomadik/include/mach/setup.h which is *wrong*,
so I would
- Create mach-nomadik/cpu-8815.h
- Move the cpu_8815_* function from <mach/setup.h>
into this file.
- Replace #include <mach/setup.h> with #include "cpu-8815.h"
in board-nhk8815.c and cpu-8815.c
- Add the reset stuff to cpu-8815.[c|h]
Feel free to fold in the below at your convenience:

Subject: [PATCH] ARM: nomadik: localize cpu-8815 header
The symbols from cpu-8815.c were being broadcast across the
entire kernel but are only really used locally in mach-nomadik
so let's localize them.

I just sent a patch for which gets reboot working on DaVinci.
I have used the arm_pm_restart hook for now. I am working on
moving the arch/arm/mach-davinci/common.h (and other local headers)
to mach-davinci folder but that needs updates to some drivers like
USB and GPIO as well. I expect to be finished in about a weeks time.
Thanks,
Sekhar

Which will break my patch queue. As I said to Tony, I'm looking to
stabilize this in about a week and a half's time, at which point
you'll be able to pull these changes into your tree.

As of today, I'm going to start freezing the restart changes, which
covers those which have been in linux-next so far. I've collected up
all the acks, etc, to date, and will not be applying any more to these
commits.
At the end of today, I'll merge these into my 'devel-stable' branch
to signify their new status, so if anyone has any objections they need
to speak up _now_.
The base set of changes are:
ARM: restart: only perform setup for restart when soft-restarting
ARM: restart: remove argument to setup_mm_for_reboot()
ARM: restart: move reboot failure handing into machine_restart()
ARM: restart: add default restart modes for PXA mioa701, spitz and tosa
ARM: restart: allow platforms more flexibility specifying restart mode
ARM: restart: add restart hook to machine_desc record
and the cleanups to prepare for the rest of the restart changes:
ARM: restart: remove poodle restart handler
ARM: w90x900: add common nuc9xx.h
ARM: clps711x: consolidate irq/mm/time code into a single file
ARM: 7159/1: OMAP: Introduce local common.h files
ARM: restart: remove local_irq_disable() from within arch_reset()

Is your reset branch stable now? I only ask because it doesn't look like
you've merged these into devel-stable so I wondered if you have any further
changes pending.
Thanks,
Will

See the message I sent to Marc about his irqchip consolidation - I was
waiting for Marc to confirm that the resolution was good before I push
the stuff over to the devel-stable branch. Marc has confirmed that
shortly after your message, so we're all good for this evening.

Ok, cracking, I'll rebase my stuff tonight or tomorrow morning.

Sure, except that pm.c now needs to include core.h (or the prototype
has to be added to pm.h). Otherwise I'm getting the following warning:
CHECK arch/arm/mach-cns3xxx/pm.c
arch/arm/mach-cns3xxx/pm.c:92:6: warning: symbol 'cns3xxx_restart' was not declared. Should it be static?
Following hunk helps:

Is this about the problem of where to place the hook
for restart as described in this message?
http://marc.info/?l=linux-arm-kernel&m=132104005724249&w=2
If you apply that patch I think it's easy to fix that up,
if you have some git branch I can base off I can fix
it up too.
Or you can just throw it into -next so it breaks and I'll fix
from there ASAP, no big deal.
Thanks,
Linus Walleij

This is about as far as I got with Nomadik. The patch you point out above
does appear to fix the problem, and if you put it in the patch system, I'll
apply it to the restart-cleanup branch, and fix the patch below.

ARM: restart: nomadik: use new restart hook XXX WIP XXX WHY IS THERE NO LOCAL HEADERS XXX
Hook the Nomadik NHK platform restart code into the new restart hook.

OK, I see.
But I did send my ack in the beginning of Nov on cover [0/7] like
following...
http://lists.infradead.org/pipermail/linux-arm-kernel/2011-November/071800.h
tml
So I didn't send my ack on this...
As a note, I'm sorting out header files, local headers in Samsung stuff as
per your suggestion and you can see them in the next week.
Anyway, thanks.
Best regards,
Kgene.
