as that's where the offending patches are coming from.

If it is this patch:

It doesn't resolve that issue. I applied it and tested on next-20190731.

If it is this patch:

https://lore.kernel.org/netdev/20190731160219.GA2114@kroah.com/

It doesn't resolve that issue. I applied it and tested on next-20190731.

This is the diff that I came up with to solve the errors plus the casting
warnings but it doesn't feel proper to me. If you all feel otherwise, I
can draft up a formal commit message.

One of the hi-lo, lo-hi writeq/readq headers has to be included.

that appeared as a result of commit 171a9bae68c7 ("staging/octeon:

With today's linux-next (20190731), I am still seeing a Kconfig warning and
build errors (building for i386):

and applying Greg's "depends on NETDEVICES" patch and this patch:

WARNING: unmet direct dependencies detected for MDIO_OCTEON
  Depends on [n]: NETDEVICES [=y] && MDIO_DEVICE [=m] && MDIO_BUS [=m] && (64BIT [=n] || COMPILE_TEST [=y]) && HAS_IOMEM [=y] && OF_MDIO [=n]
  Selected by [m]:
  - OCTEON_ETHERNET [=m] && STAGING [=y] && (CAVIUM_OCTEON_SOC || COMPILE_TEST [=y]) && NETDEVICES [=y]

ERROR: "cavium_mdiobus_write" [drivers/net/phy/mdio-octeon.ko] undefined!
ERROR: "cavium_mdiobus_read" [drivers/net/phy/mdio-octeon.ko] undefined!


kernel .config file is attached.

Am I missing another patch?

thanks.

If I add this to drivers/staging/octeon/Kconfig:
	select MDIO_OCTEON
+	select MDIO_CAVIUM
	help

then the build succeeds.

This isn't being done by make *config because MDIO_OCTEON depends on OF_MDIO,
which is not set in my .config file, so the "select MDIO_CAVIUM" in MDIO_OCTEON
is not done.

However, there are lots of type/cast warnings in both mdio-octeon and mdio-cavium:

If I add this to drivers/staging/octeon/Kconfig:

This isn't being done by make *config because MDIO_OCTEON depends on OF_MDIO,

is not done.

cavium_mdiobus.register_base should be "void __iomem *" instead of "u64",
and the cast should be dropped.

Casts are evil, and usually a sign that you're doing something wrong.

The proper way to fix this is to include either

	linux/io-64-nonatomic-hi-lo.h

or

	linux/io-64-nonatomic-lo-hi.h

whichever is appropriate.

Hmmmm, is that not what I did?

Although I did not know about io-64-nonatomic-hi-lo.h. What is the
difference and which one is needed here?

There is apparently another failure when OF_MDIO is not set, I guess I
can try to look into that as well and respin into a series if
necessary.

Cheers,

Whether you write the high or low 32 bits first.  For this, it doesn't
matter, since the compiled driver will never be run on real hardware.

That's what I figured. I have only seen lo-hi used personally, which is
what I went with here. Thanks for the confirmation!

[PATCH v2] net: mdio-octeon: Fix Kconfig warnings and build errors

After commit 171a9bae68c7 ("staging/octeon: Allow test build on
!MIPS"), the following combination of configs cause a few Kconfig
warnings and build errors (distilled from arm allyesconfig and Randy's
randconfig builds):

    CONFIG_NETDEVICES=y
    CONFIG_STAGING=y
    CONFIG_COMPILE_TEST=y

and CONFIG_OCTEON_ETHERNET as either a module or built-in.

CONFIG_OF_MDIO is not needed when CONFIG_COMPILE_TEST is enabled because
