* target/arm: Add cpu properties to control pauthRichard Henderson2021-01-191-0/+13
| | | | | | | | | | | | | | | | | | | The crypto overhead of emulating pauth can be significant for some workloads. Add two boolean properties that allows the feature to be turned off, on with the architected algorithm, or on with an implementation defined algorithm. We need two intermediate booleans to control the state while parsing properties lest we clobber ID_AA64ISAR1 into an invalid intermediate state.

* qtest: Fix bad printf format specifiersAlexChen2020-11-091-4/+4
| | | | | | | | | | We should use printf format specifier "%u" instead of "%d" for argument of type "unsigned int".

* hw/arm/virt: Implement kvm-steal-timeAndrew Jones2020-10-081-4/+21
| | | | | | | | | | | We add the kvm-steal-time CPU property and implement it for machvirt. A tiny bit of refactoring was also done to allow pmu and pvtime to use the same vcpu device helper functions.

| | | | | | | | | | | | | | | | Some cpu features may be enabled and disabled for all configurations that support the feature. Let's test that. A recent regression[*] inspired adding these tests.

* target/arm/cpu: Add the kvm-no-adjvtime CPU propertyAndrew Jones2020-01-301-0/+4
| | | | | | | | | | | | kvm-no-adjvtime is a KVM specific CPU property and a first of its kind. To accommodate it we also add kvm_arm_add_vcpu_properties() and a KVM specific CPU properties description to the CPU features document.

* test: Move qtests to a separate directoryThomas Huth2020-01-121-0/+559
The tests directory itself is pretty overcrowded, and it's hard to see which test belongs to which test subsystem (unit, qtest, ...). Let's move the qtests to a separate folder for more clarity.
