Build regressions/improvements in v5.0-rc5

Build regressions/improvements in v5.0-rc5

[Geert Uytterhoeven]

Below is the list of build error/warning regressions/improvements in
v5.0-rc5[1] compared to v4.20[2].

Summarized:
  - build errors: +2/-4
  - build warnings: +113/-14843

JFYI, when comparing v5.0-rc5[1] to v5.0-rc4[3], the summaries are:
  - build errors: +0/-0
  - build warnings: +56/-59

Note that there may be false regressions, as some logs are incomplete.
Still, they're build errors/warnings.

Happy fixing! ;-)

Thanks to the linux-next team for providing the build service.

Hi Geert,

I am trying to find the above warning (needle) in the haystack.
Can you please direct me to which config/build it is in?

Is there a good way for me to find it?

thanks.

Working backwards, it probably comes from this:

config CURRITUCK
	bool "IBM Currituck (476fpe) Support"
	depends on PPC_47x
	select SWIOTLB
	select 476FPE
	select PPC4xx_PCI_EXPRESS

This is the only similar Kconfig segment that does not select FORCE_PCI
but PPC4xx_PCI_EXPRESS depends on PCI but
# CONFIG_PCI is not set

This could be related to a recent series of patches that allows ACPI to
be built without having PCI enabled.

There isn't really an easy way to do it sorry.

If you download the page for the revision:
  http://kisskb.ellerman.id.au/kisskb/branch/linus/head/8834f5600cf3c8db365e18a3d5cac2c2780c81e5/

With a lot of grep/sed/awk you can get a list of the URLs for all the
builds eg. one would be:

  http://kisskb.ellerman.id.au/kisskb/buildresult/13676551/

And then you can just tack on "log/" to get:

  http://kisskb.ellerman.id.au/kisskb/buildresult/13676551/log/

Which you can wget and grep.

But that's all a bit of a pain.

I have on my todo list to add json formatted build results and revision
pages, which would make it quite a bit simpler. But of course I haven't
had time to do it yet :/

cheers

No problem.

However, I was trying to ask you about the kconfig problem above:

>>>>   + warning: unmet direct dependencies detected for PPC4xx_PCI_EXPRESS

and not the "search the build results" problem.  ;)

Haha, oops :)

A result of the recent rework of the PCI config symbols:

eb01d42a77785ff96b6e66a2a2e7027fc6d78e4a is the first bad commit
commit eb01d42a77785ff96b6e66a2a2e7027fc6d78e4a
Author: Christoph Hellwig <hch@lst.de>
Date:   Thu Nov 15 20:05:32 2018 +0100

    PCI: consolidate PCI config entry in drivers/pci
    
    There is no good reason to duplicate the PCI menu in every architecture.
    Instead provide a selectable HAVE_PCI symbol that indicates availability
    of PCI support, and a FORCE_PCI symbol to for PCI on and the handle the
    rest in drivers/pci.

But that patch really just exposed an existing problem. CURRITUCK
selects PPC4xx_PCI_EXPRESS which depends on PCI, and PCI is user
selectable in that config.

Previously the powerpc PCI symbol was default y for CURRITUCK so it was
enabled by default and we didn't see a warning.

But a user could always just turn it off and then they'd get the same
warning we're seeing now.

I'll send a patch to force PCI on for CURRITUCK.
