Hello all,
I am trying to add syscall in include/asm/unistd.h:
static inline _syscall0(int,my_sys_call);
But I am getting following errors :
AS arch/arm/kernel/entry-common.o include/asm/unistd.h: Assembler messages: include/asm/unistd.h:622: Error: bad instruction `static inline int my_sys_call(void){register long __res_r0 __asm__("r0")' include/asm/unistd.h:622: Error: bad instruction `long __res' include/asm/unistd.h:622: Error: bad instruction `__asm__ __volatile__("swi\t""(0x900000+322)""":"=r"(__res_r0)::"memory")' include/asm/unistd.h:622: Error: bad instruction `do {if((unsigned long)(__res)>=(unsigned long)(-129)){errno=-(__res)' include/asm/unistd.h:622: Error: junk at end of line, first unrecognized character is `}' include/asm/unistd.h:622: Error: junk at end of line, first unrecognized character is `}' include/asm/unistd.h:622: Error: junk at end of line, first unrecognized character is `}' make[1]: *** [arch/arm/kernel/entry-common.o] Error 1 make: *** [arch/arm/kernel] Error 2
This was working in older versions.
I am curious _syscall0 still exists or obsolete in 2.6 linux.
And I have noticed even if I commented _syscall0 macro, I do not get any errors so no body is using it , then why _syscall0 is in kernel header files and what is the substitute of _syscall0.
Thanks for help,
