2018-10-19hyperv: factor out arch-independent API into hw/hypervRoman Kagan
A significant part of hyperv.c is not actually tied to x86, and can be moved to hw/. This will allow to maintain most of Hyper-V and VMBus target-independent, and to avoid conflicts with inclusion of arch-specific headers down the road in VMBus implementation. Also this stuff can now be opt-out with CONFIG_HYPERV.

2018-10-19hyperv: rename kvm_hv_sint_route_set_sintRoman Kagan
There's nothing kvm-specific in it so follow the suite and replace "kvm_hv" prefix with "hyperv". Signed-off-by: Roman Kagan <rkagan@virtuozzo.com> Message-Id: <20180921081836.29230-9-rkagan@virtuozzo.com> Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
2018-10-19hyperv: make HvSintRoute reference-countedRoman Kagan
Multiple entities (e.g. VMBus devices) can use the same SINT route. To make their lives easier in maintaining SINT route ownership, make it reference-counted. Adjust the respective API names accordingly.

2018-10-19hyperv: allow passing arbitrary data to sint ack callbackRoman Kagan
Make sint ack callback accept an opaque pointer, that is stored on sint_route at creation time. This allows for more convenient interaction with the callback. Besides, nothing outside hyperv.c should need to know the layout of HvSintRoute fields any more so its declaration can be removed from the header.

2018-10-19hyperv_testdev: refactor for better maintainabilityRoman Kagan
Make hyperv_testdev slightly easier to follow and enhance in future. For that, put the hyperv sint routes (wrapped in a helper structure) on a linked list rather than a fixed-size array. Besides, this way HvSintRoute can be treated as an opaque structure, allowing for easier refactoring of the core Hyper-V SynIC code in followup pathches.

2018-07-16hyperv: rename vcpu_id to vp_indexRoman Kagan
In Hyper-V-related code, vCPUs are identified by their VP (virtual processor) index. Since it's customary for "vcpu_id" in QEMU to mean APIC id, rename the respective variables to "vp_index" to make the distinction clear.

2016-12-20Move target-* CPU file into a target/ folderThomas Huth
We've currently got 18 architectures in QEMU, and thus 18 target-xxx folders in the root folder of the QEMU source tree. More architectures (e.g. RISC-V, AVR) are likely to be included soon, too, so the main folder of the QEMU sources slowly gets quite overcrowded with the target-xxx folders. To disburden the main folder a little bit, let's move the target-xxx folders into a dedicated target/ folder, so that target-xxx/ simply becomes target/xxx/ instead.

2016-07-12Use #include "..." for our own headers, <...> for othersMarkus Armbruster
Tracked down with an ugly, brittle and probably buggy Perl script. Also move includes converted to <...> up so they get included before ours where that's obviously okay.

2015-12-17hw/misc: Hyper-V test device 'hyperv-testdev'Andrey Smetanin
'hyperv-testdev' will be used by kvm-unit-tests to setup Hyper-V SynIC SINT's routing and to inject Hyper-V SynIC SINT's. Hyper-V test device is ISA type device that creates 0x3000 IO memory region and catches write access into it. Every write operation data decoded into ctl code and parameters for Hyper-V test device.
