2018-03-07RISC-V Physical Memory ProtectionMichael Clark
Implements the physical memory protection extension as specified in Privileged ISA Version 1.10. PMP (Physical Memory Protection) is as-of-yet unused and needs testing. The SiFive verification team have PMP test cases that will be run. Nothing currently depends on PMP support. It would be preferable to keep the code in-tree for folk that are interested in RISC-V PMP support.

2018-03-06balloon: Fix documentation of the --balloon parameter and deprecate itThomas Huth
There are two issues with the documentation of the --balloon parameter: First, "--balloon none" is simply doing nothing. Even if a machine had a balloon device by default, this option is not disabling anything, it is simply ignored. Thus let's simply drop this option from the documentation to avoid to confuse the users (but keep the code in vl.c for backward compatibility). Second, the documentation claims that "--balloon virtio" is the default mode, but this is not true anymore since commit 382f074371f7dc32a34. Since that commit, the option also has no real use case anymore, since you can simply use "--device virtio-balloon" nowadays instead. Thus to simplify our complex parameter zoo a little bit, let's deprecate the the parameter now and tell the user to use "--device virtio-balloon" instead.

In this case its possible that we set an invalid memory section of the next call for DeliverabilityNotifications that was not expected.

2018-03-06qmp: Add qom-list-properties to list QOM object propertiesAlexey Kardashevskiy
There is already 'device-list-properties' which does most of the job, however it does not handle everything returned by qom-list-types such as machines as they inherit directly from TYPE_OBJECT and not TYPE_DEVICE. It does not handle abstract classes either. This adds a new qom-list-properties command which prints properties of a specific class and its instance. It is pretty much a simplified copy of the device-list-properties handler. Since it creates an object instance, device properties should appear in the output as they are copied to QOM properties at the instance_init hook. This adds a object_class_property_iter_init() helper to allow class properties enumeration uses it in the new QMP command to allow properties listing for abstract classes.

2018-03-06scsi: Remove automatic creation of SCSI controllers with -drive if=scsiThomas Huth
Automatic creation of SCSI controllers for "-drive if=scsi" for x86 machines was quite a bad idea (see description of commit f778a82f0c179 for details). This is marked as deprecated since QEMU v2.9.0, and as far as I know, nobody complained that this is still urgently required anymore. Time to remove this now.

2018-03-06Remove the deprecated -tdf optionThomas Huth
It's been marked as deprecated since a very long time already, and the parameter is not doing anything useful anymore except for printing a warning, so it's now time to finally get rid of this option.

2018-03-06PowerPC: Add TS bits into msr_maskSimon Guo
During migration, after MSR bits is synced, cpu_post_load() will use msr_mask to determine which PPC MSR bits will be applied into the target side. Hardware Transaction Memory(HTM) has been supported since Power8, but TS0/TS1 bit was not in msr_mask yet. That will prevent target KVM from loading TM checkpointed values. This patch adds TS bits into msr_mask for Power8, so that transactional application can be migrated across qemu.
