fio: fix cycles_start build issue There is an issue introduced with "commit 73df3e07 gettime: offset CPU cycle counter by initial value". For architectures which define ARCH_CPU_CLOCK_CYCLES_PER_USEC (currently only s390) this causes a build error gettime.c:174:11: error: ‘cycles_start’ undeclared (first use in this function) if (t < cycles_start && !cycles_wrap) To make sure variables and code are only compiled in the same cases I added a clock definition called ARCH_CPU_CLOCK_WRAPS. We could merge ARCH_CPU_CLOCK_WRAPS and the existing ARCH_CPU_CLOCK_CYCLES_PER_USEC into one if you prefer, so far nobody else uses it. To avoid cluttering all architecture headers I enabled it by default in arch-generic.h, so any arch not needing the wrap handling can undef ARCH_CPU_CLOCK_WRAPS later in their headers.

fio: fix s390 timing for older machines/binutils Older gcc/binutils or one with very low default march will refuse to use stckf. On top of that machines older than a z196 don not even have the store clock fast facility. To fix all of those issues, check for the facilities in configure step and make the usage of stckf and a matching march dependent to it.

fio: fix s390 nop When trying to run rate limited fio runs we encountered that the current definition of a nop uses a privileged instruction which is not even a nop, but a yield call to the hipervisor. That leads to a SIGILL as it is privileged. To solve that issue replace it with a nop, the assembler will take care of it (likely to become a BCR 0,0) Signed-off-by: Christian Ehrhardt <ehrhardt@linux.vnet.ibm.com> Signed-off-by: Jens Axboe <axboe@fb.com>

fio: fix s390 time accounting The current timer implementation could cause time warps on s390 which ends up as time bound jobs that would never end, because they always reset themself to the old time. When touching this code anyway, we also change it to use the faster stckf and avoid the calibration as we can control the result to be usecs. This also eliminates a few calculations cycle->usec in the hot path for the timer. In case other architectures have similar improved timers that might not be usec based, but nsec based or such a thing any architecture can set ARCH_CPU_CLOCK_CYCLES_PER_USEC to an appropriate per-arch value. This leaves the infrastructure open for others and the compiler will throw our division by 1 away anyway.
