[PATCH 0/4] More COMPILE_TEST patches to build all media drivers on x86_64

[PATCH 0/4] More COMPILE_TEST patches to build all media drivers on x86_64

[Mauro Carvalho Chehab]

While now all media drivers build with COMPILE_TEST on i386, there are still
a few of them that don't build on x86_64.

Making them compiling there is just a matter of touching Kconfig files.

While here, fix smatch warnings when building the siano driver on big endian
architectures.

[PATCH 1/4] media: radio: allow building ISA drivers with COMPILE_TEST

[Mauro Carvalho Chehab]

Several radio devices only build on i386, because they depend
on ISA. Allow them to build on other archs by adding a
COMPILE_TEST check.

[PATCH 2/4] media: sta2x11_vip: allow build with COMPILE_TEST

[Mauro Carvalho Chehab]

This driver doesn't use any weird API. So, allow building it
with COMPILE_TEST.

[PATCH 3/4] sound, media: allow building ISA drivers it with COMPILE_TEST

[Mauro Carvalho Chehab]

All sound drivers that don't depend on PNP can be safelly
build with COMPILE_TEST, as ISA provides function stubs to
be used for such purposes.

As a side effect, with this change, the radio-miropcm20
can now be built outside i386 with COMPILE_TEST.

Kconfig complains with "select ISAPNP":

WARNING: unmet direct dependencies detected for ISAPNP
  Depends on [n]: PNP [=y] && ISA [=n]
  Selected by [y]:
  - SND_AD1816A [=y] && SOUND [=y] && !UML && SND [=y] && SND_ISA [=y] && PNP [=y]

Because it is declared as:

config ISAPNP
	bool "ISA Plug and Play support"
        depends on ISA

I could have tried to change ISAPNP to depends on ISA || COMPILE_TEST,
but I suspect that would touch on yet another subsystem and has
the potential to point to other things that need changes, as
a lot more drivers will be selected.

Anyway, after a quick look at include/linux/isapnp.h, I suspect
that this can work.

I'll run some tests here.

Thanks,
Mauro

I see.  Then it'd be better to put this explanations in the changelog
as well.

At least a dumb stub is there, so let's hope we can widen the test
coverage :)

Yes, that's the idea :-)

Right now, for every patch I receive, I build media drivers for i386
(I just made all of them build on i386), but I'm considering doing such
builds on x86_64 instead, as it also enables compat32 code.

Thanks,
Mauro

[PATCH v2] sound, media: allow building ISA drivers it with COMPILE_TEST

All sound drivers that don't depend on PNP can be safelly
build with COMPILE_TEST, as ISA provides function stubs to
be used for such purposes.

As a side effect, with this change, the radio-miropcm20
can now be built outside i386 with COMPILE_TEST.

It should be noticed that ISAPNP currently depends on ISA.
So, on drivers that depend on it, we need to add an
explicit dependency on ISA, at least until another patch
removes it.

Signed-off-by: Mauro Carvalho Chehab <mchehab@s-opensource.com>

v2: only patch description changed, with the addition of a note
about ISA explicit dependency on 3 drivers.

Yes, removing the ISAPNP dependency if COMPILE_TEST is trivial too.

Just sent a separate patch to be applied after this one with such
removal.

I opted to make it as a separate patch as, if the drivers there
fail to build on some weird architecture, we won't need to discard
this one.

OK, then feel free to take my ack:
  Acked-by: Takashi Iwai <tiwai@suse.de>

But still it'd be better to mention about the CONFIG_ISA change, even
though it'll be removed again after the ISAPNP COMIPLE_TEST patch.


thanks,

It's not actually a bug that was introduced by the commit, but it just
made appearing clearer.  So I dropped this tag.

Get rid of them by adding explicit forced casts.
