kvm: move target-dependent interrupt routing out of kvm-all.c

2024-05-03T13:47:48Z

Let hw/hyperv/hyperv.c and hw/intc/s390_flic.c handle (respectively) SynIC and adapter routes, removing the code from target-independent files. This also removes the only occurrence of AdapterInfo outside s390 code, so remove that from typedefs.h. Signed-off-by: Paolo Bonzini

hw, target: Add ResetType argument to hold and exit phase methods

2024-04-25T09:21:06Z

We pass a ResetType argument to the Resettable class enter phase method, but we don't pass it to hold and exit, even though the callsites have it readily available. This means that if a device cared about the ResetType it would need to record it in the enter phase method to use later on. Pass the type to all three of the phase methods to avoid having to do that.

vmbus: Print a warning when enabled without the recommended set of features

2024-03-08T13:18:56Z

Some Windows versions crash at boot or fail to enable the VMBus device if they don't see the expected set of Hyper-V features (enlightenments). Since this provides poor user experience let's warn user if the VMBus device is enabled without the recommended set of Hyper-V features. The recommended set is the minimum set of Hyper-V features required to make the VMBus device work properly in Windows Server versions 2016, 2019 and 2022.

hv-balloon: define dm_hot_add_with_region to avoid Coverity warning

2024-03-08T13:18:56Z

Since the presence of a hot add memory region is optional in hot add request message it wasn't part of this message declaration (struct dm_hot_add). Instead, the code allocated such enlarged message by simply adding the necessary size for this extra field to the size of basic hot add message struct. However, Coverity considers accessing this extra member to be an out-of-bounds access, even thought the memory is actually there. Fix this by adding an extended variant of this message that explicitly has an additional union dm_mem_page_range at its end. CID: #1523903 Signed-off-by: Maciej S. Szmigiero

hv-balloon: avoid alloca() usage

2024-03-08T13:18:56Z

alloca() is frowned upon, replace it with g_malloc0() + g_autofree. Reviewed-by: Philippe Mathieu-Daudé Reviewed-by: David Hildenbrand Signed-off-by: Maciej S. Szmigiero

hv-balloon: use get_min_alignment() to express 32 GiB alignment

2024-02-04T16:42:03Z

Let's implement the get_min_alignment() callback for memory devices, and copy for the device memory region the alignment of the host memory region. This mimics what virtio-mem does, and allows for re-introducing proper alignment checks for the memory region size (where we don't care about additional device requirements) in memory device core.

vmbus: Switch bus reset to 3-phase-reset

2024-02-02T13:51:57Z

Switch vmbus from using BusClass::reset to the Resettable interface. This has no behavioural change, because the BusClass code to support subclasses that use the legacy BusClass::reset will call that method in the hold phase of 3-phase reset.

hyperv: Clean up includes

2024-01-30T18:20:20Z

This commit was created with scripts/clean-includes: ./scripts/clean-includes --git hyperv hw/hyperv/*.[ch] All .c should include qemu/osdep.h first. The script performs three related cleanups: * Ensure .c files include qemu/osdep.h first. * Including it in a .h is redundant, since the .c already includes it. Drop such inclusions. * Likewise, including headers qemu/osdep.h includes is redundant. Drop these, too.
