Please enlighten me why this isn't + sclp_mark_busy(); + h->length = 8; + sclp_setup_int(); + + asm volatile( + " .insn rre,0xb2204200,%1,%2\n" /* servc %1,%2 */ + " ipm %0\n" + " srl %0,28" + : "=&d" (cc) : "d" (valid_code), "a" (__pa(pagebuf)) + : "cc", "memory"); + if (!cc) + sclp_wait_busy(); + report(cc == 0, "Instruction format ignored bits"); I feel like I am missing something important. -- Thanks, David / dhildenb
