possibilities of these as the instruction is made up of a 0xA opcode & the second byte being
the syscall number. They are traced using the simple command.
TR SVC <Optional value or range>
-the syscalls are defined in linux/include/asm-s390/unistd.h
+the syscalls are defined in linux/arch/s390/include/asm/unistd.h
e.g. to trace all file opens just do
TR SVC 5 ( as this is the syscall number of open )
