I'll provision a ppc64 machine and verify the patch for both
64- and 32-bit builds. Presuming that works, queued for crash-6.0.6.
Thanks,
Dave
Well, as luck would have it, this patch does not work with 32-bit PPC:

I don't suppose it's as easy as just adding an ABI_PPC #define here
in sial_api.h:
/* abi values */
#define ABI_MIPS 1
#define ABI_INTEL_X86 2
#define ABI_INTEL_IA 3
#define ABI_S390 4
#define ABI_S390X 5
#define ABI_PPC64 6
and setting SIAL_ABI to it here in sial.c?:
#ifdef i386
#define SIAL_ABI ABI_INTEL_X86
#else
#ifdef __ia64__
#define SIAL_ABI ABI_INTEL_IA
#else
#ifdef __x86_64__
#define SIAL_ABI ABI_INTEL_IA
#else
#ifdef __s390__
#define SIAL_ABI ABI_S390
#else
#ifdef __s390x__
#define SIAL_ABI ABI_S390X
#else
#ifdef PPC64
#define SIAL_ABI ABI_PPC64
#else
#error sial: Unkown ABI
#endif
#endif
#endif
#endif
#endif
#endif
And I'm not mistaken, SIAL_ABI is pretty much useless. Aside
from getting #define'd above, it's only used here:
sial_apiset(&icops, SIAL_ABI, sizeof(long ), 0);
and that function apparently ignores it entirely:
void
sial_apiset(apiops *o, int abi, int nbpw, int sign)
{
def_t *dt;
sial_ops=o?o:&nullops;
sial_setdefbtype(nbpw, sign);
/* get the pre defines and push them. */
dt=API_GETDEFS();
while(dt) {
sial_newmac(dt->name, dt->val, 0, 0, 1);
dt=dt->next;
}
/* add the sial define */
sial_newmac(sial_strdup("sial"), sial_strdup("1"), 0, 0, 1);
}
Or am I missing something?
But if I do add a new ABI_PPC #define, it builds, and shows this:
# file ./extensions/snap.so
./extensions/snap.so: ELF 32-bit MSB shared object, PowerPC or cisco 4500, version 1
(SYSV), dynamically linked, with unknown capability 0x41000000 = 0x13676e75, with unknown
capability 0x10000 = 0xb0401, not stripped
#
whereas the native PPC64 version shows this:
# file extensions/sial.so
extensions/sial.so: ELF 64-bit MSB shared object, 64-bit PowerPC or cisco 7500, version 1
(SYSV), dynamically linked, not stripped
#
And it doesn't load the 32-bit version:
crash> extend sial.so
extend: ./extensions/sial.so: not an ELF format object file
crash>
But that is probably a crash issue, because *none* of the extension
modules built as 32-bit PPC objects will load:
crash> extend snap.so
extend: ./extensions/snap.so: not an ELF format object file
crash> extend echo.so
extend: ./extensions/echo.so: not an ELF format object file
crash>
And "file" shows the additional baggage for them as well:
# file extensions/snap.so
extensions/snap.so: ELF 32-bit MSB shared object, PowerPC or cisco 4500, version 1
(SYSV), dynamically linked, with unknown capability 0x41000000 = 0x13676e75, with unknown
capability 0x10000 = 0xb0401, not stripped
#
So anyway, I'm going to leave the patch in place, wait for your
answer re: creating an API_PPC #define, and also look into the
reason behind the load failure.
