2020-06-16s390/crypto: use scnprintf() instead of snprintf()Chen Zhou1-7/+7
snprintf() returns the number of bytes that would be written, which may be greater than the the actual length to be written. show() methods should return the number of bytes printed into the buffer. This is the return value of scnprintf().

2020-06-16s390/qdio: reduce SLSB writes during Input Queue processingJulian Wiedmann3-50/+20
Streamline the processing of QDIO Input Queues, and remove some intermittent SLSB updates (no deleting of old ACKs, no redundant transitions through NOT_INIT). Rather than counting ACKs, we now keep track of the whole batch of SBALs that were completed during the current polling cycle. Most completed SBALs stay in their initial state (ie. PRIMED or ERROR), except that the most recent SBAL in each sub-run is ACKed for IRQ reduction. The only logic changes happen in inbound_handle_work(), the other delta is just a renaming of the variables that track the SBAL batch. Note that in particular we don't need to flip the _oldest_ SBAL to an idle state (eg. NOT_INIT or ACKed) as a guard against catching our own tail. Since get_inbound_buffer_frontier() will never scan more than the remaining nr_buf_used SBALs, this scenario just doesn't occur.

2020-06-16s390/ptrace: fix setting syscall numberSven Schnelle1-1/+30
When strace wants to update the syscall number, it sets GPR2 to the desired number and updates the GPR via PTRACE_SETREGSET. It doesn't update regs->int_code which would cause the old syscall executed on syscall restart. As we cannot change the ptrace ABI and don't have a field for the interruption code, check whether the tracee is in a syscall and the last instruction was svc. In that case assume that the tracer wants to update the syscall number and copy the GPR2 value to regs->int_code.

2020-06-16s390/qdio: fine-tune SLSB updateJulian Wiedmann1-1/+8
xchg() for a single-byte location assembles to a 4-byte Compare&Swap, wrapped into a non-trivial amount of retry code that deals with concurrent modifications to the unaffected bytes. Change it to a simple byte-store, but preserve the memory ordering semantics that the CS provided. This simplifies the generated code for a hot path, and in theory also allows us to amortize the memory barriers over multiple SLSB updates.

2020-06-16drm/i915/gt: Incrementally check for rewindingChris Wilson6-4/+154
In commit 5ba32c7be81e ("drm/i915/execlists: Always force a context reload when rewinding RING_TAIL"), we placed the check for rewinding a context on actually submitting the next request in that context. This was so that we only had to check once, and could do so with precision avoiding as many forced restores as possible. For example, to ensure that we can resubmit the same request a couple of times, we include a small wa_tail such that on the next submission, the ring->tail will appear to move forwards when resubmitting the same request. This is very common as it will happen for every lite-restore to fill the second port after a context switch. However, intel_ring_direction() is limited in precision to movements of upto half the ring size. The consequence being that if we tried to unwind many requests, we could exceed half the ring and flip the sense of the direction, so missing a force restore. As no request can be greater than half the ring (i.e. 2048 bytes in the smallest case), we can check for rollback incrementally. As we check against the tail that would be submitted, we do not lose any sensitivity and allow lite restores for the simple case. We still need to double check upon submitting the context, to allow for multiple preemptions and resubmissions.

2020-06-16drm/i915/gt: Prevent timeslicing into unpreemptable requestsChris Wilson3-2/+119
We have a I915_REQUEST_NOPREEMPT flag that we set when we must prevent the HW from preempting during the course of this request. We need to honour this flag and protect the HW even if we have a heartbeat request, or other maximum priority barrier, pending. As such, restrict the timeslicing check to avoid preempting into the topmost priority band, leaving the unpreemptable requests in blissful peace running uninterrupted on the HW. v2: Set the I915_PRIORITY_BARRIER to be less than I915_PRIORITY_UNPREEMPTABLE so that we never submit a request (heartbeat or barrier) that can legitimately preempt the current non-premptable request.
