The user is working with QEMU and added a new syscall (436) but is getting ENOSYS from the MIPS application. They modified the mips/cpu_loop.c by adding an entry to mips_syscall_args. The issue seems to be that the syscall number is being calculated as env->active_tc.gpr[2] - 4000, and if that number is beyond the size of mips_syscall_args, it returns ENOSYS. + +Wait, the user mentioned that the ARM version has its own ARM_NR_BASE, which probably adjusts the syscall numbers correctly. The MIPS code might not be accounting for the correct base value, leading to the syscall_num being out of bounds. For example, if the actual syscall number is 436, but the base is 4000 (as in ARM's case), subtracting 4000 would give a negative number, which would definitely be beyond the array size, hence ENOSYS. + +So the problem is that the MIPS code isn't using a base value like ARM does. The user wants to refactor MIPS's cpu_loop.c to handle syscalls similarly to ARM. The root cause is that the syscall number calculation isn't correct for MIPS, leading to the wrong index in the syscall_args array. This is a syscall handling issue because the syscall number isn't being adjusted properly, causing it to fall into the ENOSYS case. + +The classification options are instruction, syscall, or runtime. Since the problem is about the syscall number not being handled correctly, the category should be "syscall". +</think> + +syscall \ No newline at end of file |
