2015-11-06replay: ptimerPavel Dovgalyuk
This patch adds deterministic replay for hardware periodic countdown timers. ptimer uses bottom halves layer to execute such an asynchronous callback. We put this callback into the replay queue instead of bottom halves one. When checkpoint is met by main loop thread, the replay queue is processed and callback is executed. Binding callback moment to one of the checkpoints makes it deterministic.

2015-11-06replay: recording and replaying clock ticksPavel Dovgalyuk
Clock ticks are considered as the sources of non-deterministic data for virtual machine. This patch implements saving the clock values when they are acquired (virtual, host clock). When replaying the execution corresponding values are read from log and transfered to the module, which wants to read the values. Such a design required the clock polling to be synchronized. Sometimes it is not true - e.g. when timeouts for timer lists are checked. In this case we use a cached value of the clock, passing it to the client code.

2015-11-05target-i386: Set "check=off" by default on pc-*-2.4 and olderEduardo Habkost
The default CPU model (qemu64) have some issues today: it enables some features (ABM and SSE4a) that are not present in many host CPUs. That means many hosts (but not all of them) had those features silently disabled in the default configuration in QEMU 2.4 and older. With the new "check=on" default, this causes warnings to be printed in the default configuration, because of the lack of SSE4A on all Intel hosts, and the lack of ABM on Sandy Bridge and older hosts: $ qemu-system-x86_64 -machine pc,accel=kvm warning: host doesn't support requested feature: CPUID.80000001H:ECX.abm [bit 5] warning: host doesn't support requested feature: CPUID.80000001H:ECX.sse4a [bit 6] Those issues will be fixed in pc-*-2.5 and newer. But as we can't change the guest ABI in pc-*-2.4, disable "check" mode by default in pc-*-2.4 and older so we don't print spurious warnings.

2015-10-29virtio: introduce virtio_mapMichael S. Tsirkin
virtio_map_sg currently fails if one of the entries it's mapping is contigious in GPA but not HVA address space. Introduce virtio_map which handles this by splitting sg entries. This new API generally turns out to be a good idea since it's harder to misuse: at least in one case the existing one was used incorrectly. This will still fail if there's no space left in the sg, but luckily max queue size in use is currently 256, while max sg size is 1024, so we should be OK even is all entries happen to cross a single DIMM boundary. Won't work well with very small DIMM sizes, unfortunately: e.g. this will fail with 4K DIMMs where a single request might span a large number of DIMMs. Let's hope these are uncommon - at least we are not breaking things. Note: virtio-scsi calls virtio_map_sg on data loaded from network, and validates input, asserting on failure. Copy the validating code here - it will be dropped from virtio-scsi in a follow-up patch.
