[PATCH v3 09/11] s390: mm: Convert to GENERIC_IOREMAP

[PATCH v3 09/11] s390: mm: Convert to GENERIC_IOREMAP

[Baoquan He]

By taking GENERIC_IOREMAP method, the generic ioremap_prot() and
iounmap() are visible and available to arch. Arch only needs to
provide implementation of arch_ioremap() or arch_iounmap() if there's
arch specific handling needed in its ioremap() or iounmap(). This
change will simplify implementation by removing duplicated codes with
generic ioremap() and iounmap(), and has the equivalent functioality
as before.

For s390, add hooks arch_ioremap() and arch_iounmap() for s390's special
operation when ioremap() and iounmap(), then ioremap_[wc|wt]() are
converted to use ioremap_prot() from GENERIC_IOREMAP.

v2->v3:
- Add code comment inside arch_ioremap() to help uderstand the
  obsucre code. Christoph suggested this, Niklas provided the
  paragraph of text.

The above compiling errors are caused by unsetting CONFIG_PCI in
s390-buildonly-randconfig-r006-20221009 attached. I keep the items for
reference. Because s390 puts io mem functions in arch/s390/pci/pci.c.
While building arch/s390/pci/pci.c in needs CONFIG_PCI enabled. I don't
think disabling CONFIG_PCI in s390x makes sense in reality, except of
the randconfig testing.

Hi Niklas, lkp

What do you think about this? We can just ignore this building error
with randconfig in lkp?

Hmm, that's a bummer. As s390 systems (aka mainframes) do have classic
channel devices for networking and permanent storage that are currently
even more common than PCI devices you can definitely have a fully
functional system with CONFIG_PCI=n. Also the drivers for these channel
devices do not use ioremap() which is only used for PCI, so in theory
it should be fine not to have ioremap() for CONFIG_PCI=n.

I think the reason for this concrete failure to compile is a missing
HAS_IOMEM dependency for CONFIG_QCOM_HIDMA. I'm not sure how many other
cases there are though as I think we might be the only ones where
HAS_IOMEM is only sometimes available (it depends on CONFIG_PCI for
us). Ideally I think we would have the driver dependencies. I'm a bit
confused though since in the current code it looks to me like
ioremap_prot() will be declared but not defined for CONFIG_PCI=n too as
far as I can tell at least.

Thanks for detailed explanation.

I built the latest upstream kernel with the randconfig, it has the issue
either, please see below build log snippet. Means if CONFIG_PCI is unset,
it has problem with the current s390 code.

Yeah, depending on HAS_IOMEM for QCOM_HIDMA can fix it. And in
drivers/pcmcia/cistpl.c, there are ioremap()/iounmap() calling too.
Make PCMCIA depend on HAS_IOMEM can fix it. 

ioremap_prot() will called outside if CONFIG_HAVE_IOREMAP_PROT is
enabled. With this patchset, it will only be declared and defined when
CONFIG_GENERIC_IOREMAP is enabled. Please correct me if I'm wrong.

Below draft change can fix the compiling errors with the randconfig on
s390 as you suggested. We may need post the driver code change in
another patch since it's not related to this patchset?

Subject: [PATCH] s390, ioremap: fix
Content-type: text/plain

On s390 systems (aka mainframes), it has classic channel devices for
networking and permanent storage that are currently even more common
than PCI devices. Hence it's likely to have a fully functional s390
kernel with CONFIG_PCI=n.

So let GENERIC_IOREMAP depend on PCI in s390 arch since the drivers for
those channel devices do not use ioremap() which is only used for PCI,
in theory it should be fine not to have ioremap() for CONFIG_PCI=n.

And let QCOM_HIDMA and PCMCIA PCMCIA depend on HAS_IOMEM so that they
won't be built if PCI is unset.

I think you should add the "if PCI" from the diff in your last mail to
this patch.

Gave this a round of testing on s390 with both the MIO and non-MIO
cases. I also see you addressed my previous comments and it looks good
to me. As you showed in the other mail the compile error is a pre
existing problem so shouldn't influence this change. So assuming you
add the "if PCI" and the nit above you can add my:

That's reasonable, will do.

The code change in driver should be posted separately to get reviewing
from the relevant drvier maintainers. I may wrap it into this series in
next post so that people know its background.

Sorry, remember you pointed this out in v2, while I didn't get what
it is. Could you be more specific or give the right line of code?

Are you suggesting below line? 

-	return (void __iomem *) ((unsigned long) area->addr + offset);
+		return (void __iomem *)*paddr;

I agree about doing the driver change separately. Since the problem
already exists one could send it separately. If you want I can take of
that too.

Yes, though I did just check and somehow checkpatch doesn't complain,
maybe because of the dereference. I do think I remember it complaining
but I guess if it doesn't you might as well keep it this way.
