Hmm. I'm getting this when testing:

warning: (AHCI_XGENE) selects PHY_XGENE which has unmet direct
dependencies (HAS_IOMEM && OF && (ARM64 || COMPILE_TEST))

which looks like AHCI_XGENE doesn't have the proper dependency on OF (or alternatively PHY_XGENE has an incorrect dependemcy on OF).

According to google it looks like Fengguang reported this on kbuild-all, but nowhere else.

The actual build then succeeds. But the Kconfig warning is real and implies that something is seriously wrong wrt the dependencies for this thing.

It looks like the "select PHY_XGENE" came in through the libata update, but this USB update actually brought in the "config PHY_XGENE" and thus this error. Which makes me wonder how this all worked. Why does that "select PHY_XGENE" exist when apparently it's not needed?

Regardless, there's something broken somewhere.

Linus

Odd, I don't know what to do to fix this up "properly".

Loc Ho, this came in from your patch, any ideas?

thanks,

greg k-h

Hi,

I don't think it has anything to do with USB. With the current dependency, X-Gene SATA AHCI driver will be included if either ARM64 or COMPILE_TEST. It in turn will select "PHY_XGENE" which has dependency on OF and HAS_IOMEM. An fix would be make AHCI_XGENE depends on OF as suggested by Linus. This is trigger by "COMPILE_TEST" for non-ARM64. We can also remove "COMPILE_TEST" from AHCI_XGENE driver like other SATA drivers. My prefer solution is to remove "COMPILE_TEST".

-Loc

Hi,

Shouldn't we let the users to enable PHY_XGENE (maybe add in the platform defconfig)?

Thanks
Kishon

Hi,

The idea that PHY drivers have to be explicitly enabled to make other drivers work doesn't sound very attractive. I would prefer to go with Loc's idea of dropping COMPILE_TEST dependency and making the AHCI_XGENE driver available only on ARM64.

Best regards,

Hi,

This is another option but PHY_XGENE is required by AHCI_XGENE . If one selects AHCI_XGENE, it should select its dependency.

-Loc

Applied the following patch to libata/for-3.15-fixes.

Thanks.

AHCI_XGENE is only applicable on ARM64 but it can also be enabled for compile testing; however, AHCI_XGENE selects PHY_XGENE which has other arch specific dependencies. This leads to the following warning when enabling it on other archs for compile testing.

warning: (AHCI_XGENE) selects PHY_XGENE which has unmet direct dependencies (HAS_IOMEM && OF && (ARM64 || COMPILE_TEST))

Let's drop COMPILE_TEST from AHCI_XGENE.

So, apparently, this isn't enough as this would allow enabling PHY_XGENE regardless of HAS_IOMEM or OF. From kconfig-language.txt,

Note:
select should be used with care. select will force a symbol to a value without visiting the dependencies. By abusing select you are able to select a symbol FOO even if FOO depends on BAR that is not set.
In general use select only for non-visible symbols (no prompts anywhere) and for symbols with no dependencies. That will limit the usefulness but on the other hand avoid the illegal configurations all over.

We can add all the necessary dependencies to AHCI_XGENE but I think the the right thing to do is turning it into a proper dependency. Will prep another patch.

Thanks.

Hello, Kishon.

I'm converting AHCI_XGENE to depend on PHY_XGENE instead of selecting it as dependency chaining through select doesn't work. Looking at the PHY Kconfig options, I wonder whether we're going about this the right way. Are PHY drivers meaningful at all w/o higher level drivers making use of them? If not, why do we even have visible Kconfig opts for them? Shouldn't we just chain everything through selects and float the actual dependencies to the higher level drivers which the users actually care about?

Thanks.

tejun

Hi,

PHY_XGENE has the following dependencies:

	depends on HAS_IOMEM && OF && (ARM64 || COMPILE_TEST)

So it should be OK.

Please note that ARM64 implies that HAS_IOMEM and OF are _always_ selected. This is the reason why removing "|| COMPILE_TEST" from AHCI_XGENE dependencies is sufficient to fix the issue (though I have to admit that relying indirectly on ARM64 selects is a bit hacky).

Hmmm, the alternative idea is to remove PHY_XGENE reference from AHCI_XGENE altogether and add:

default y if AHCI_XGENE

to PHY_XGENE instead (which seems to be not as hacky as solution with "select PHY_XGENE" and also more user-friendly than "depends on PHY_XGENE" one).

Best regards,

Hello,

...

This being okay is so not obvious. Let's either float all dependencies to the higher level drivers or just use "depends on". I really dislike mixing the two and playing games with the subtle combinations. For now, I'm making it all "depends on". Please feel free to improve on it as necessary.

The config dependencies should be indicative the actual dependency. AHCI_XGENE is useless without PHY_XGENE; then, the config dependency *must* represent that. That's the priority.

It is true that users probably won't care about PHY_XGENE or any PHY drivers probably, but, again, let's please not mix depends and selects in contrived manner to hit the just right mixture of the two. Let's please do it systematically. Float all actual deps to the surface to the options that the users configuring care about and propagate down to phy drivers using select. Our config system *really* doesn't work with mixed depends and selects. I mean, think about the suggested solution. It works only because there's no actual linkage dependency between the two, ARM64 implies HAS_IOMEM && OF, AND we omitted COMPILE_TEST for a completely obscure reason. I don't think that's acceptable.

Thanks.

warning: (AHCI_XGENE) selects PHY_XGENE which has unmet direct dependencies (HAS_IOMEM && OF && (ARM64 || COMPILE_TEST))

Selecting a config option which itself has dependencies can easily lead to broken configurations. For now, let's just make AHCI_XGENE depend on PHY_XGENE which has all the necessary dependencies already.
