I am working with qemu on test images. I've added a new syscall (436) to qemu but received ENOSYS from mips application. Please open "linux-user/mips/cpu_loop.c". I've added at the end of "mips_syscall_args" the following: ``` MIPS_SYS(sys_getdents64_x32, 3) ``` But ``` syscall_num =3D env->active_tc.gpr[2] - 4000; if (syscall_num >=3D sizeof(mips_syscall_args)) { ret =3D -TARGET_ENOSYS; ``` returns -TARGET_ENOSYS We can see that "linux-user/mips/cpu_loop.c" differs a lot from "linux- user/arm/cpu_loop.c". Arm has it's own "ARM_NR_BASE" and etc. Can you please refactor mips cpu loop in the same way as arm?
