[1/9] stringify: add HEX_STRING()

Commit Message

Randy Dunlap July 10, 2011, 7:51 p.m. UTC

From: Randy Dunlap <[e-mail]>

Add HEX_STRING(value) to stringify.h so that drivers can
convert kconfig hex values (without leading "0x") to useful
hex constants.

Several drivers/media/radio/ drivers need this.  I haven't
checked if any other drivers need to do this.

Alternatively, kconfig could produce hex config symbols with
leading "0x".

Hi Randy,

After applying patch 1/9 and 2/9 over 3.0-rc7+media patches, I'm
now getting this error:

drivers/media/radio/radio-aimslab.c:52:1: error: invalid suffix "x20f" on integer constant

$ grep 20f .config
CONFIG_RADIO_RTRACK_PORT=20f

$ gcc --version
gcc (GCC) 4.4.5 20110214 (Red Hat 4.4.5-6)

Before this patch, this were working (or, at least, weren't producing
any error).

Perhaps the breakage on your compilation happened due to another
patch at the tree? If so, the better would be to apply this patch
series together with the ones that caused the breakage, to avoid
bisect troubles.

Hi Mauro,

I built all of these drivers with my patches applied,
but I'll see if I can find where this error is coming from.

Thanks for checking & letting me know.

Actually, I used to have a patch to make hex value have a mandatory
"0x" prefix, in the Kconfig. I even fixed all the issue in the tree,
it never make it to the tree (not sure why). Here's the relevant
thread:

I prefer that this be fixed in kconfig, so long as it won't cause
any other issues.  That's why I mentioned it.

It's a common idiom for concatenating strings in the kernel.

How would you do it without (instead of) a kconfig fix/patch?

Do you suspect that?

I built this patch series against the latest linux-next (20110707),
so it should contain media patches as of that date.

Sure, if we know what patch it is (if there indeed is one).

Can you do:
$ make drivers/media/radio/radio-aimslab.i

and tell me what this line contains for you?
Mine says:

static int io = 0x20f;

I meant hackish not because *how* it is done, but because *why* it has
to be done, that is, because the Kconfig miss the prefix, which is
really no big deal.

have the Kconfig use the "0x" prefix since the beginning.

Sure, go for it.  I'll ack it.  ;)  [or Review it :]
and test it.
