Re: [vpp-dev] Make pkg-rpm seems to be failing...
Ugh, I made a terrible bone head mistake... Possibly I never ran make install-dep. Even if I had, I was unaware that it is a good idea to run it again, just to be sure, in a case like this. I probably thought it was like make bootstrap, where running a 2nd time doesn't help. Apologies to Ed and Ole for misinformation. So, Jon, were you in the same boat with me -- didn't do a double check of make install-dep? I guess so, because you still had the problem after Ole's fix.

Re: [vpp-dev] problems in mips32
According to your suggestion，I re-write "clib_calljmp" in longjmp.S,and it also
passes test_longjmp.c;but it doesn't work in vpp, still segmentation fault when
excute a system call.
At last time, I saving return address(ra) and old stack-pointer(old sp) in
register s6 and s7, this time I saved them in new stack.
I don't think Ra and old stack is the key of the question, becuase the function
crashes before it returns.
Here is the code；
.text
.global clib_calljmp
.align 4;
.ent clib_calljmp,0;
.type clib_calljmp,@function
clib_calljmp:
move $10, $29 //sp->t2 backup old sp
li $9, 4 //t1 = 4
subu $8, $6, $9 //t0 = a2 - t1 new sp -4
move $29, $8 //t0->sp write new sp in register sp
addiu $29,$29,-8
sw $31,4($29) //push ra
sw $10,0($29) //push old stack
move $25, $4 //a0->t9 new function
move $4, $5 //a1->a0 new function arg
jalr $25 //jump
nop
lw $31,4($29) //pop ra
lw $29,0($29) //pop old stack
jr $31 //return
.end clib_calljmp;

Please make sure that src/vppinfra/test_longjmp.c passes before you move on.
You’ve undoubtedly pickled the stack and/or one or more of the registers.
Clib_calljmp is always the source of subsequent issues.
The code you wrote belongs in longjmp.S. Trying to write clib_calljmp(...) in C
/ doing the dirty work in an asm volatile makes it all but inevitable that GCC
will get in the way.
Even though it’s been a long time since I wrote MIPS assembler code: I don’t
see where you’re saving clib_calljmp’s return address and old stack-pointer on
the new stack.
If you expect people to even try to help you with assembly code, comments are
essential.
Thanks… Dave

Guys,
I'm looking forward to run vpp in mips32 arch,but problem was caused by
"clib_calljmp","clib_setjmp" and "clib_longjmp". There is no code for mips32 in
vpp, so I wrote them by myself, and they worked very well in my test program,
However,when I run vpp with them, segmentation fault was happend when excute a
system call like "open","SYS_clock_gettime",etc.
The "stack" in "clib_calljmp" was alloced by "clib_mem_alloc_aligned", It is
strange that if I did not use "clib_mem_alloc_aligned" but with "malloc", the
problem is still there but less happened. Sometimes it occurs, but sometimes
it's ok.
Here is the code I worte for mips32.
uword clib_calljmp (uword (*func) (uword func_arg), uword func_arg, void *stack)
{
unsigned long ret=0;
__asm__ volatile (
".set push \n"
"move $23, $29\n"
"li $9, 4\n\t"
"subu $8, %3, $9\n\t"
"sll $8, $8, 0\n\t"
"move $29, $8\n\t"
"move $9, %1\n\t"
"move $4, %2\n\t"
"move $25,$9\n\t"
"move $22, $31\n\t"
"jalr.hb $25\n\t"
"nop\n\t"
"move %0, $2\n\t"
"move $29,$23\n"
"move $31, $22\n\t"
".set pop\n"
:"=r"(ret)
:"r"(func),"r"(func_arg),"r"(stack)
:"$8","$9","$23","$22"
);
return ret;
}
Thanks,
Xinying Xue
