[LTP] MIPS/MIPS64 syscalls

[He Zhe]

Hi All,

There seems not any mips/mips64 syscalls defined. Where can we find them? or do we support them?

ls include/lapi/syscalls/
aarch64.in? hppa.in? ia64.in? powerpc64.in? regen.sh? s390x.in? sparc64.in? strip_syscall.awk
arm.in????? i386.in? order??? powerpc.in??? s390.in?? sh.in???? sparc.in??? x86_64.in

Some cases like rt_sigtimedwait01 would fail without the definition.

./testcases/kernel/syscalls/sigwaitinfo/sigwaitinfo01.c
#ifdef TEST_RT_SIGTIMEDWAIT?????????????????????????????????????????????????????
static int my_rt_sigtimedwait(const sigset_t * set, siginfo_t * info,???????????????????????????????????????????????????????????????????????
????????????????????????????? struct timespec *timeout)?????????????????????????
{???????????????????????????????????????????????????????????????????????????????
????????????????????????????????????????????????????????????????????????????????
??????? /* The last argument is (number_of_signals)/(bits_per_byte), which are 64 and 8, resp. */
??????? return ltp_syscall(__NR_rt_sigtimedwait, set, info, timeout, 8);????????
}???????????????????????????????????????????????????????????????????????????????
#endif


Thanks,
Zhe

You need to create these files based on the numbers defined in kernel
syscall tables, look at arch/mips/kernel/syscalls/*.tbl, then you need
to add newly added architectures into the order file so that the headers
are generated correctly.

Also it looks like there are two 32bit ABIs there though not sure if we
need to support both in LTP though.
