I've posted these before and now gotten around to a rebase and
want to include them in the arm-soc next/multiplatform branch for
4.5.
Originally the plan for these platforms was to convert all of
them to DT and use only mach-mvebu. That has not happened,
so I would do it this way instead so we can at least have
them in a single kernel.
Let me know if there are any concerns or objections.

ARM: orion: always use MULTI_IRQ_HANDLER
ARM: orion: use SPARSE_IRQ everywhere

The watchdog device node is created in plat-orion/common.c
but depends on the bridge address that is platform specific,
so as a preparation for orion multiplatform support, we should
move it out of the common code into orion5x.
The other two users of plat-orion currently do not support
the watchdog device, so this is not a problem.

As a preparation for multiplatform support, this enables
the MULTI_IRQ_HANDLER code unconditionally on dove and
orion5x, and introduces the respective code on mv78xx0,
which did not have it so far. The classic entry-macro.S
files are removed as they are now obsolete.

As a preparation for multiplatform support, this moves all the
code using plat-orion over to use sparse irq support, which is
enabled implicitly for multiplatform.
In particular, the hardcoded NR_IRQS macro gets replaced with
a machine specific one that is set in the machine descriptor
in order to set up a static mapping for all legacy interrupts.

This is a simple move of all header files that are no longer
included by anything else from the include/mach directory
to the platform directory itself, for mv78xx0, dove, and orion5x,
as preparation for multiplatform support.
The mach/uncompress.h headers are left in place for now,
and are mildly modified to be independent of the other
headers. They will be removed entirely when ARCH_MULTIPLATFORM
gets enabled and they become obsolete.
Rather than updating the path names inside of the comments
of each header, I delete those comments to avoid having to
update them again, should they get moved or copied another
time.

From: Arnd Bergmann @ 2015-11-25 15:49 UTC (permalink / raw)
To: linux-arm-kernel
Cc: linux-kernel, Jason Cooper, Andrew Lunn, Sebastian Hesselbarth,
Gregory Clement, Russell King, Arnd Bergmann
All three remaining orion based platforms are now ready to
be enabled for multiplatform support, this patch does the
switch over by modifying the Kconfig file, the defconfig and
removing the last mach/*.h header that becomes obsolete with
this.

Maybe we should just remove mv78xx0? It has been at least two years
since we have heard of anybody using it, outside of Debians now
replaced build system. And its IRQ handling is broken apparently.
Russell, you are the last known user of mach-dove. What are your
plans? You keep saying you have given up trying to mainline your Cubox
patches. Have you really given up? Can we remove mach-dove?
Orion5x is still used, we occasionally get drive-by patches.

Actually I was about to remove it last year but an mv78200 user came
with a bug fix on the gpio driver used by this platform:
http://marc.info/?l=linux-arm-kernel&m=140639461108781&w=2
While he seemed interseted to use a mainline kernel we don't have any
news for one year:

Right now, I'm developing etnaviv in spare time on the Cubox[*], which
is still primarily running a non-DT kernel.
It's actually a kernel that I've hacked which is capable of booting
both DT and non-DT, but even when booted in DT mode, I still require
much of the arch/arm/mach-dove infrastructure to get things like
armada-drm, etnaviv and other drivers running. Especially because
we're missing things like the high-speed clocks (the stuff above the
tclk domain.) I've not even started to work out how to get that
into mainline, or how to integrate that with CCF. Quite what can be
done with the audio patches, I've no idea, that remains a bone of
contention and stalemate, and currently isn't DT-able. See the list
of patches at the end of this message...
It feels today like I'm the only one working on improving Dove support,
and so it's going to take a _long_ time to move things forward - it's
likely to take years. I have many demands on my time and I have to
divide it up between the various aspects.
Eg, it's taken me a whole year to get the second batch of patches for
the component helper out the door... most of the time I can't see the
trees for all the patches I'm carrying.
* - I'm fed up with waiting for etnaviv to mature; I've been waiting
two years so far in the hope that others will do the work and finally
provide everyone with a solution to the closed source userspace blob.
Consequently, I don't have much time to push Dove stuff forwards right
now - though it can be argued that etnaviv _is_ pushing Dove forwards.
Omitting historical galcore and current etnaviv patch sets, I have 115
patches for Cubox support outstanding.
Note: some of those 115 patches have been merged during the 4.4 merge
window (eg, the tda998x changes and armada drm changes) though I won't
be in a position to know what the new state of affairs are until after
4.4 has been released - where upon I will (as normal) rebase my entire
cubox patch set on the next released kernel.

Hi Russell
The problem from our side is the apparent lack of progress. We get so
very few patches we wounder why we should keep it around. If there was
even a steady trick of patches, we would feel better about keeping it.
So looking at this list, could you maybe post the following, if they
don't have dependencies. Going from only the subject, most look simple
and should not be too much effort to get mainlined.

You may think there's lack of progress, but I can tell you that there's
lots of progress on etnaviv right now. Since 1st November, I've
authored 100 MESA patches, 81 of those merged into Christians repository.
I've also been sorting out issues with the kernel side driver, which
now supports cross-GPU synchronisation, necessary for iMX6, and a
necessary step towards getting the kernel driver merged into mainline.
As I already explained, there is only one of me. I can only do so much,
and I tend to focus on one part of the broad problem to the exclusion of
other parts - I find chopping and changing all the time to be a much
less efficient way of working.
Others may be able to do a little bit here, a little bit there, but I'm
not like that, sorry.
I won't be able to even start thinking about looking at this stuff until
next week - Arnd wants me to look at some patches he's sent out today,
which I might be able to do tomorrow afternoon at the very earliest,
and I'm probably not around on Friday.
See - I'm only one person, I don't have time to be able to progress
lots of non-paying work at a fast rate.
You'll have to wait, just like I've had to wait to get my own patches
for other stuff in, just like I have to wait for progress in other
projects. Sorry, but waiting and patience is all part of open source
development, especially when it relies upon volunteer effort.

I think the same discussed was what stopped my series on the last
two attempts. If there are no objections to things that I'm doing,
I'd suggest we just merge the multiplatform patches that we want
for orion5x and dove anyway and then decide about removing mv78xx0 ;-)

I think it's ok to keep mach-dove around for a longer time to keep the
board file, I'm way more interested in completing the multiplatform
work at last.
If I understand you right, being able to build mach-dove and mach-mvebu
together will actually help you remove one or more of your patches,
but of course will require a small bit of rebasing.

This is something I already do, and it's trivial to make it work.
You're doing it by moving some includes around, I've found that it's
not necessary to move any includes around what so ever.
The problem I have right now is that people are expecting me to do
everything at once: people want me to write documentation for the
component helper. People want me to merge more Dove patches. People
want me to merge the Armada 38x work I have queued. People are wanting
to get the etnaviv kernel driver out for merging this week, now that
I've solved the final part of the etnaviv puzzle - but yesterday I've
uncovered another user API issue that needs to be discussed and
resolved.
You know, there aren't enough me's to do everything - people just have
to get used to the idea that if they're not willing to put the work in
(iow, I have to put the work in) then things are going to be slow for
anything that isn't funded work, because I have a lot on my plate.
In the case of Dove, I only ever look at the current state of things
once every kernel cycle, as I only ever update the tree to a final
kernel release. That means it takes about five months between
submission and seeing the result of those patches merged, so I can
then sort through what other stuff needs to be sent. Why six months?
Get it queued for the next merge window (which can be up to six to
eight weeks away). Then wait a full kernel cycle (eight to ten weeks)
for it to appear in a final kernel. That's 14 to 18 weeks.
The last stuff which was merged was the PMU driver, merged in August.
It's taken until 4.3 for this to become "visible" in my Dove tree.
I should, at some point during this cycle - depending on my available
time - start looking at what other pieces I can send, but what I'm
saying is that this is the _earliest_ opportunity I have to start
looking again at this.
Meanwhile, during this last merge window, more Armada DRM patches have
gone in, along with some TDA998x patches - both of which I term Dove
patches because that's their applicable kernel tree that they get
tested with.
Meanwhile, Etnaviv is progressing, which again, is a Dove thing,
because the Dove has a Vivante GC600 GPU, which etnaviv drives.
Meanwhile, Andrew's complaining that he's not seen anything from me
for a long time. What Andrew can't see is that the work is going on
at the peripheral driver level, not at the core level, /because/ it's
the peripheral drivers which are blocking me dropping the non-DT
support.

It's really not that simple. Remember what base this tree is: it is
Rabeeh's kernel tree from 3.4 times, with _each_ mainline release
merged into it and a patch set of 250+ patches rebased forwards.
A lot of these patches do not easily apply to mainline kernels.

Adding linux/clk.h to plat-orion/clock.c to solve some build errors,

Adding linux/clkdev.h to clk-si5351.c to fix build errors caused by
4.3 changes breaking previous tweaks to make it work in non-DT setups.
Not applicable to mainline without previous tweaks.

Adds to the non-DT cubox board file a DT descriptor to pick up on
the existing cubox compatible, and to hook into the "old style"
initialisation to allow etnaviv/armada-drm/vmeta/bmm to work.

Only applicable if you have the hwmon driver.

A possible fix for mainline if we're keeping non-DT tauros2 support around.

Possibly not applicable with Arnd's work.

Not applicable because mainline has no non-DT cubox board file.

All the above are cleaning up the "missing bits" of the clock tree for
the GPU/CPU/vmeta clocks - the stuff that's clocked off the main 2GHz
PLL. No support in mainline for this, and would need to be converted to
a CCF driver.

hwmon is something that needs to be dealt with, but is nowhere near

Not applicable to mainline; it's reverting a patch in Rabeeh's tree.
> > ARM: dove: convert legacy dove to PMU support
This one got dropped due to conflicts. It's now rebased on 4.3 (which
is the earliest final kernel release it could be based upon, as the
PMU code and conflicting changes were merged in the 4.3 merge window),
I can finally think about resending it.
> > dt-bindings: add Marvell PMU documentation
Was sent in March and July, and obviously if it's still in my git tree,
it never ended up being merged, and needs investigation as to what
happened, and why it hasn't been merged along with the code.
> > of: Add vendor prefix for Vivante Corporation
Part of the etnaviv patch set.
So, out of all those matches, maybe one or two patches can be sent
immediately. That still leaves me with about a hundred patches
which are reliant on the non-DT dove code.

I have applied all the patches on mvebu/oldmvebu_multiplatform (I fixed
the last one which didn't apply on Kconfig). I also merged it
mvebu/for-netx to be part of the linux-next.
But before making it part of mvebu/soc, I would like to get some
Tested-by. The series is available on
git://git.infradead.org/linux-mvebu.git
in the branch mvebu/oldmvebu_multiplatform but it also will be part soon
of linux-next.
Russell, Sebastian,
would you have some time to test it on Dove?
Detlef, Benjamin,
could you test it on an Orion5x based board?
Evgeniy,
could you test it on an mv78xx0 base board?
Actually we consider removing the support for this SoC unless there are
some user interested on them. As you are the last one claiming using a
mainline kernel on a mv78xx0, keeping the support will mainly depends on
you :)
Thanks,
Gregory

Hi Gregory
I blew the dust of my Orion5x NAS Reference Design. It boots.
Tested-by: Andrew Lunn <andrew@lunn.ch>
It would be nice to make Orion5x part of the multi_v5_defconfig and
mvebu_v5_defconfig. I will see about cooking up some patches.

Given that I'm testing on my Cubox tree, I've applied this series on top
of v4.3. Patch 5 trivially conflicts on MMP context. Fixing that and
merging the resulting changes gives another load of conflicts which need
dealing with:
Recorded preimage for 'arch/arm/Kconfig'
Recorded preimage for 'arch/arm/mach-dove/Kconfig'
Recorded preimage for 'arch/arm/mach-dove/irq.c'
Recorded preimage for 'arch/arm/mach-dove/pm.h'
These look less trivial to resolve, so testing this will have to wait
until I have sufficient time to sort this out.

Hi Gregory
To help with testing, could you pull the defconfig changes into the
branch? I cannot boot the multi_v5_defconfig on my Orion5x. Its CPU is
too old, and needs CONFIG_CPU_FEROCEON_OLD_ID, but that is not
available because CPU_ARM926T is enabled.
Thanks

I have pushed a rebased version to

As I said above, that's not the problem, the problem is merging it into
the rest of my tree.
Having done most of that merge, I'm now tripping up on:
arch/arm/mach-dove/common.c: In function 'dove_wdt_init':
arch/arm/mach-dove/common.c:538:2: error: implicit declaration of function 'orion_wdt_init' [-Werror=implicit-function-declaration]
which I guess is because you've deleted the legacy orion watchdog stuff.
So I'm going to have to revert that. That then gives me:
arch/arm/mach-dove/clock.c:19:21: fatal error: mach/pm.h: No such file or directory
arch/arm/mach-dove/clock.c:20:27: fatal error: mach/hardware.h: No such file or directory
The first is easy to solve, and the second by replacing it with dove.h.
The next problem is this:
arch/arm/plat-orion/common.c:25:30: fatal error: mach/bridge-regs.h: No such file or directory
which is impossible to solve, because plat-orion/common.c wants
mach-dove/bridge-regs.h.
I also have arch/arm/mach-dove/include/mach/sdhci.h to pass the GPIO
for card detection to the SDHCI driver, which is going to break unless
it's moved to include/linux/platform-data.
Everything else seems mostly happy, but I've no way to tell whether
what would be the resulting kernel would work as it's impossible to
know without fixing the wreckage above.
I'm sure I don't have to repeat my position over what I'm going to do if
these petty mainline changes which are totally unnecessary break the only
setup I have which works. Making mach-dove multi-platform is a "wouldn't
it be nice if", it's not an absolute necessity.

Another few breakages which is going to be difficult to solve:
drivers/hwmon/dove.c:35:30: fatal error: mach/bridge-regs.h: No such file or directory
drivers/soc/dove/pmu.c: In function 'dove_init_pmu_legacy':
drivers/soc/dove/pmu.c:404:46: error: 'IRQ_DOVE_PMU_START' undeclared (first use in this function)
drivers/soc/dove/pmu.c:404:46: note: each undeclared identifier is reported only once for each function it appears in
So, all in all this series gets a NAK from me as it totally destroys
my ability to do any further work on Dove.

Ok, I can try to work around that, either by duplicating the device definition,
or passing the address into orion_wdt_init.

Right, a platform_data file seems the right approach there. Possibly just
passing the gpio number by casting it to a pointer, though that's a bit
ugly.

I'm mostly interested in it because it's the only ARMv7 platform that is
left after my other patches, and I just want to be done with it after
spending 5 years on it ;-)

Ok, I'll try to take out the dove specific parts that get in the way here
but would still do the whole series for mv78xx0 and orion5x unless someone
finds problems.

My understanding is that the long term goal is to delete mach-dove once
everyone has settled down into the mvebu DT world.
Right now we have mvebu which covers Dove using DT. We have mach-dove
which is legacy non-DT Dove.
It seems to me to be completely crazy to want to bring legacy code, which
is ultimately destined to be deleted, into multiplatform.

I agree. We have multiplatform dove already, it is in mach-mvebu. Do
we really need both mach-dove and mach-mvebu dove in one kernel?

Only to support my efforts in adding further Dove support. As you
know, we've recently added PMU support, and I've recently sent you
patches for the remaining clocks. Both of those are laying the
foundations for the next big piece, which is support for the GPU
on Dove.
Most of the effort that's been going on recently has been for the GPU
support has been invisible to most people, because much of that is
around hammering out the DRM API for it, and getting the thing stable.
This is a bigger project than just Dove, other SoCs also have the same
GPU family in them, even having multiple separate GPU cores. It's
taken a lot of effort and time to hammer this out between three people
Lucas, Christian, and myself.
Some of the problems are only visible using the graphics stack which
I have: xf86-video-armada (which is 2D GPU accelerated for any of these
GPUs which support it) vs Christian's MESA (which obviously uses the 3D
GPU.) On Dove, it's fairly simple, because the GPU core there is a
combined 2D/3D affair, but iMX6 has separate cores, so I've had to come
up with a way to synchronise between the cores (which obviously can have
an effect on the user API, and therefore must be resolved prior to the
initial submission.)
The mach-dove code is key to my involvement with this.
So, please realise that things have been _real_ busy on Dove, even though
you have not seen much from me: that'll be quite normal when most of the
effort is going on outside of something being Dove platform specific.
What Lucas and myself have been working towards since 4.2 is to get the
kernel GPU driver into a state where we can get it merged: we've had the
DRM people review it, and they've provided feedback. It's taken a long
time to work through that feedback, which included totally ripping out
the existing locking and replacing it with a completely new locking scheme
- which is never an easy thing to do. (Lucas had a few goes, I also had a
few goes, and eventually we ended up with something that is fairly sane but
has one very hairy place which was difficult to solve.)
Getting this sorted so I can then drop the galcore chunk of code out of
my dove tree will be a major step forwards for me, and will allow me to
eliminate the reason that I've not been willing to publish the tree in
full (because, despite galcore being a supposedly open source kernel
driver which lots of people - including companies - seem happy to
distribute, there is at least one file in it which do not carry the open
source boilerplate, but instead carry a more restrictive license, which
as far as I'm concerned makes me unable to publish this code.)
Talking about publishing... I do wonder what use that would be. A while
back, people were asking me to publish it, and I arranged to publish as
much as I could, which included BMM, vmeta, PMU and other associated
components. The result of that came to nothing at all, except a more
complicated git tree for me to manage which has added to my workload, and
thus slowed me down more... in hind sight, I don't know why I bothered.

I'm also fine with deleting mach-dove, but that would be much more
disruptive to Russell's work, so I don't think that helps anyone.
I've rebased the series to leave out the last two patches for dove,
and added the watchdog on dove, so I can at least get the other
patches out of my queue if that works for now.

Ah, maybe i worded that badly. By "in one kernel" i mean kernel
binary. We should keep mach-dove, and allow a mach-dove build of the
kernel. But there is no reason for that build to be multi-platform. We
already have multi-platform dove via mvebu.
Anyway, i see your v2 patches do leave mach-dove as a single platform
kernel.

Can you send me your config file? I can have a look.

I've done a quick check with an allnoconfig-like test and it seems that
CONFIG_OF is weighing in at around 86K here, with all the other options
it pulls in, comparing an allnoconfig kernel for DS-323 with one that
has CONFIG_OF enabled as well.
The multiplatform kernel also enables CONFIG_OF unconditionally, but is
otherwise a little smaller than the mach-orion5x based one:

The first and third row are without my patches, once they are applied,
ARCH_ORION becomes a sub-option of ARCH_MULTIPLATFORM.

Correct. I was a bit surprised at how much object code enabling CONFIG_OF
adds these days, it used to be a lot less, but you are right that
disabling CONFIG_OF is not possible with the way that ARCH_MULTIPLATFORM
is structured.
It was always the plan to move all orion5x machines over to use CONFIG_OF
eventually, so you get that overhead one way or another, and at least
it looks like doing multiplatform on top of OF doesn't add any noticeable
extra overhead (the total numbers are actually smaller).
It may also be worth investigating what has made CONFIG_OF so costly,
maybe we can reduce this a bit again.

I'm not too happy about adding 80kb to the uncompressed kernel
image either. I've spent some more time now trying to find where
we added the bloat. It's mainly in drivers, not in arch specific
code, a kilobyte here and there eventually adds up, but the largest
portion with a little over 50% of the total diff is drivers/of.
I don't expect to find a lot of low-hanging fruit there. For
reference, see the diff of 'size -A' below.

Wasn't there an idea kicked around a while ago to create a
dt2boardfile script/executable*? Then, during kernel configuration, you
enable it and select which dts file you want. It would disable
CONFIG_OF, multiplatform, etc. And generate a board_file.c from the dts
file.
If anything, it might be worth asking the kernel tinification [1], [2]
folks if they'd be interested in taking this on...
thx,
Jason.

I think you are right this has come up in the past, but I don't see how
it would work in practice without significant changes to driver subsystems:
The way we describe devices in DT is often very different from what we
have for the traditional board files, and in some cases we don't even
support platform data any more, so this would still depend on having
properties according to the DT bindings, and require a large chunk of
the same code that is doing DT at the moment.

yes, that's unfortunate. Perhaps the tinification links are still
helpful to Detlef.

No objection if you want to add it to the task list on
tiny.wiki.kernel.org (on the more difficult end).
I don't know if you could generate a board file, but I do wonder if you
could effectively compile in a parsed description and ditch the parser.
Bonus if you can make the values parsed out of it into compile-time
constants for constant folding.

After a bit of discussion with Arnd on irc, I agree. Going to a board
file doesn't really work since the logic is now mostly in the drivers
probe functions.
The dts parsing -> compile-time constants is worth looking into.

Jason.

SYSFS_DEPRECATED can probably go, initramfs would be smaller than initrd

SLOB would be smaller than SLAB, kexec is often not needed.

I have no idea why SWIOTLB is always enabled on ARM, I suspect that's
a bug, and disabling it would save some space (need to change arm/Kconfig)

Loop and RAM could be loadable modules, if that saves space in the
end. If modules are actually larger, you can have everything built-in.

No need for 8250_FSL or 8250_DMA on your hardware

It looks like you get two GPIO drivers for the same hardware.
We should probably change this so you only need one of the two.

You probably don't have a PCI EHCI

probably not needed since you have no specific driver for it.

EXT2 no longer needs to be built when EXT4 is enabled, you can just
use the EXT4 code to mount EXT2 file systems.

XFS is huge. If you don't need it, that would likely save more than anything
else.

minixfs is almost never needed, but small.

NFS and NFSD are also pretty big, but I assume you need them.
