Subject: Which architectures need 64-bit resources?
Date: Mon, 6 Nov 2006 05:23:37 -0700	[thread overview]
Message-ID: <20061106122337.GK27140@parisc-linux.org> (raw)

I have a patch sitting in the parisc tree which does:

 config RESOURCES_64BIT
-       bool "64 bit Memory and IO resources (EXPERIMENTAL)" if (!64BIT && EXPER
IMENTAL)
+       bool "64 bit Memory and IO resources (EXPERIMENTAL)" if (!64BIT && !PARI
SC && EXPERIMENTAL)
        default 64BIT

This is a bit selfish really, and it'll lead to something pretty ugly and
unmaintainable ...

+       bool "64 bit Memory and IO resources (EXPERIMENTAL)" if (!64BIT && !PARISC && !M68K && !AVR && !CRIS && !FRV && !H8300 && !M32R && !S390 && !SUPERH && !SPARC && !V850 && !XTENSA && EXPERIMENTAL)

at least if my understanding of those arches needs is correct.  Much better
to have the dependencies be positive:

+       bool "64 bit Memory and IO resources (EXPERIMENTAL)" if (!64BIT && (ARM || X86 || MIPS || PPC) && EXPERIMENTAL)

Do I have that set of architectures right?  Any others that need 64 bit
resource types?  Any there that shouldn't be there?  Should we ditch
the EXPERIMENTAL tag at the same time?
