Use s390_cpu_virt_mem_write() so we can actually revert what we did (re-inject the dequeued IO interrupt). Signed-off-by: NDavid Hildenbrand <david@redhat.com> Message-Id: <20180129125623.21729-10-david@redhat.com> Signed-off-by: NCornelia Huck <cohuck@redhat.com>

Move floating interrupt handling into the flic. Floating interrupts will now be considered by all CPUs, not just CPU #0. While at it, convert I/O interrupts to use a list and make sure we properly consider I/O sub-classes in s390_cpu_has_io_int().

This is a preparation for floating interrupt support and only applies to MTTCG, single threaded TCG works just fine. If a floating interrupt wakes up a VCPU and the CPU thinks it can run (clearing cs->halted), at the point where the interrupt would be delivered, already another VCPU might have picked up the interrupt, resulting in a wakeup without an interrupt (executing wrong code). It is wrong to let the VCPU continue to execute (the WAIT PSW). Instead, we have to put the VCPU back to sleep.

Let the flic device handle it internally. This will allow us to later on store floating interrupts in the flic for the TCG case. This now also simplifies kvm.c. All that's left is the fallback interface for floating interrupts, which is now triggered directly via the flic in case anything goes wrong.

We currently only support CRW machine checks. This is a preparation for real floating interrupt support. Get rid of the queue and handle it via the bit INTERRUPT_MCHK. We don't rename it for now, as it will be soon gone (when moving crw machine checks into the flic). Please note that this is the same way also KVM handles it: only one instance of a machine check can be pending at a time. So no need for a queue. While at it, make sure we try to deliver only if env->cregs[14] actually indicates that CRWs are accepted. Drop two unused defines on the way (we already have PSW_MASK_...).

In alpine docker image the qemu-system-s390x build is broken and it throws this error: qemu-system-s390x: Initialization of device s390-ipl failed: could not load bootloader 's390-ccw.img' The grep command of busybox uses regex. This fails on binary data (e.g. stops on every \0), so it does not identify the string BiGeNdIaN in the test case big/little. Therefore, it assumes that the architecture is little endian.

To make our efforts on QEMU testing easier to consume by contributors, let's add a document. For example, Patchew reports build errors on patches that should be relatively easy to reproduce with a few steps, and it is much nicer if there is such a documentation that it can refer to. This focuses on how to run existing tests and how to write new test cases, without going into the frameworks themselves. The VM based testing section is moved from tests/vm/README which now is a single line pointing to the new doc.

qemu_co_queue_next does not need to release and re-acquire the mutex, because the queued coroutine does not run immediately. However, this does not hold for qemu_co_enter_next. Now that qemu_co_queue_wait can synchronize (via QemuLockable) with code that is not running in coroutine context, it's important that code using qemu_co_enter_next can easily use a standardized locking idiom. First of all, qemu_co_enter_next must use aio_co_wake to restart the coroutine. Second, the function gains a second argument, a QemuLockable*, and the comments of qemu_co_queue_next and qemu_co_queue_restart_all are adjusted to clarify the difference.

There are cases in which a queued coroutine must be restarted from non-coroutine context (with qemu_co_enter_next). In this cases, qemu_co_enter_next also needs to be thread-safe, but it cannot use a CoMutex and so cannot qemu_co_queue_wait. Use QemuLockable so that the CoQueue can interchangeably use CoMutex or QemuMutex.

QemuLockable is a polymorphic lock type that takes an object and knows which function to use for locking and unlocking. The implementation could use C11 _Generic, but since the support is not very widespread I am instead using __builtin_choose_expr and __builtin_types_compatible_p, which are already used by include/qemu/atomic.h. QemuLockable can be used to implement lock guards, or to pass around a lock in such a way that a function can release it and re-acquire it. The next patch will do this for CoQueue.

Using "fedora:latest" makes behavior different depending on when you actually pulled the image from the docker repository. In my case, the supposedly "latest" image was a Fedora 25 download from 8 months ago, and the new "test-debug" test was failing. Use "27" to improve reproducibility and make it clear when the image is obsolete.
