This is the fifth version of the nds32 port. In order for nds32 port
to catch up the glibc 2.30 release, we removed the hard-fp support from
the nds32 port because the outdated soft-fp module in the kernel caused 21
glibc test cases to fail. All CPU-relative information can be found from
<http://www.andestech.com/en/products-solutions/product-documentation/>.
The ISA and ABI used in nds32 ports are documented in the "AndeStar ISA Manual"
and "Andes Programming Guide for ISA V3", respectively.

The patchest has been cross-tested on the FPGA board based on Linux 5.0
and glibc commit 119269606996. In addition to the known
architecture-independent issues on the per-release wiki pages, there are two
unexpected FAIL cases, libio/tst-wfile-sync and misc/tst-syscall-list,
The reasons for their failure are as follows.

1. libio/tst-wfile-sync
In the testcase, an unexpected Error code -ESPIPE retunred by the function
xlseek() causes this testcase to fail. This is an architecture independent
issue and I has reported it to Bugzilla (Bug 24668).

2. misc/tst-syscall-list
The reason for the failure is that udftrap is missing from syscall-names.list.
This syscall only exists in Linux 5.0 and 5.1 and will be renamed to
fp_udfiex_ctrl in Linux 5.2. Should I send a patch which adds udftrap
into syscall-names.list, and resend a patch for renaming after the default
kernel version in build-many-glibcs.py is changed to 5.2? or I only send one
patch which adds fp_udfiex_ctrl to syscall-names.list and note this failed case
as a known issue?

We can mention any name we want in syscall-names.list.  Users will only
see SYS_ names that match their kernel headers and their __NR_ names.
So we can add fp_udfiex_ctrl to the list at any time.  I can review a
patch to that affect if you send it.

Thanks,

Is there a requirement for defaulting to 32-bit blkcnt_t in glibc?
The kernel for nds32 has only ever supported 64-bit here, so it
seems a bit pointless to use a smaller range in user space.

Same for these

and these

Starting with linux-5.1, you can also use 64-bit time_t.

I get it, but I has a little question. The syscall-names.list is used for
kernel 5.1 and the udftrap has not been renamed to fp_udfiex_ctrl in this version.
Hence the missing system call is udftrap instead of fp_udfiex_ctrl. Could I
temporarily add udftrap to the list ? When syscall-names.list is for kernel 5.2,
I will send another patch to rename udftrap to fp_udfiex_ctrl.

Thanks for your kind help

Regards
Vincent

Just add both, permanently.  The additional known name doesn't hurt, and
perhaps it will be used again.

For nds32, I think your suggestions are reasonable but I have a question about
rlim_t. The 2nd argument of function sys_getrlimit and sys_setrlimit is struct
rlimit which consists of 2 __kernel_ulong_t data, rlim_cur and rlim_max, in
the kernel. If I change the type of rlim_t to unsigned long long, the data type
of these two parameters does not match between kernel and linux. I know that
if the macro __RLIM_T_MATCHES_RLIM64_T is defined as 1, glibc will replace the
system calls getrlimit and setrlimit with prlimit64, and this problem does not
exist. However, user still can use indirect system call, syscall, to issue
getrlimit and setrlimit. So, does the data type of rlim_t still keep as
unsigned long in glibc? or I need to send a patch to kernel to undefine the
__ARCH_WANT_SET_GET_RLIMIT for nds32.

OK


Thanks,

I think the behavior you need is to set __RLIM_T_MATCHES_RLIM64_T
and define struct rlimit and rlim_t as 64 bit types.

Using syscall() directly from user space has lots of other problems when
the kernel data types and the user space types don't match, e.g. calling
clock_gettime() won't work when you have a 64-bit time_t, that needs to
be clock_gettime64().

Removing __ARCH_WANT_SET_GET_RLIMIT, __ARCH_WANT_STAT64,
and __ARCH_WANT_TIME32_SYSCALLS would be nice in theory to keep
the ABI clean and the kernel small, but we can't do that if anyone is
still using binaries that call these. Whether those exist is probably out
of your control, so the saver option is to keep them around forever.
