2019-11-01target/arm/kvm: host cpu: Add support for sve<N> propertiesAndrew Jones4-17/+35
Allow cpu 'host' to enable SVE when it's available, unless the user chooses to disable it with the added 'sve=off' cpu property. Also give the user the ability to select vector lengths with the sve<N> properties. We don't adopt 'max' cpu's other sve property, sve-max-vq, because that property is difficult to use with KVM. That property assumes all vector lengths in the range from 1 up to and including the specified maximum length are supported, but there may be optional lengths not supported by the host in that range. With KVM one must be more specific when enabling vector lengths.

2019-11-01target/arm/cpu64: max cpu: Support sve properties with KVMAndrew Jones3-42/+242
Extend the SVE vq map initialization and validation with KVM's supported vector lengths when KVM is enabled. In order to determine and select supported lengths we add two new KVM functions for getting and setting the KVM_REG_ARM64_SVE_VLS pseudo-register. This patch has been co-authored with Richard Henderson, who reworked the target/arm/cpu64.c changes in order to push all the validation and auto-enabling/disabling steps into the finalizer, resulting in a nice LOC reduction.

kvm_arm_create_scratch_host_vcpu() takes a struct kvm_vcpu_init parameter. Rather than just using it as an output parameter to pass back the preferred target, use it also as an input parameter, allowing a caller to pass a selected target if they wish and to also pass cpu features. If the caller doesn't want to select a target they can pass -1 for the target which indicates they want to use the preferred target and have it passed back like before.

2019-11-01target/arm/cpu64: max cpu: Introduce sve<N> propertiesAndrew Jones5-2/+250
Introduce cpu properties to give fine control over SVE vector lengths. We introduce a property for each valid length up to the current maximum supported, which is 2048-bits. The properties are named, e.g. sve128, sve256, sve384, sve512, ..., where the number is the number of bits. See the updates to docs/arm-cpu-features.rst for a description of the semantics and for example uses. Note, as sve-max-vq is still present and we'd like to be able to support qmp_query_cpu_model_expansion with guests launched with e.g. -cpu max,sve-max-vq=8 on their command lines, then we do allow sve-max-vq and sve<N> properties to be provided at the same time, but this is not recommended, and is why sve-max-vq is not mentioned in the document. If sve-max-vq is provided then it enables all lengths smaller than and including the max and disables all lengths larger. It also has the side-effect that no larger lengths may be enabled and that the max itself cannot be disabled. Smaller non-power-of-two lengths may, however, be disabled, e.g. -cpu max,sve-max-vq=4,sve384=off provides a guest the vector lengths 128, 256, and 512 bits. This patch has been co-authored with Richard Henderson, who reworked the target/arm/cpu64.c changes in order to push all the validation and auto-enabling/disabling steps into the finalizer, resulting in a nice LOC reduction.

Since 97a28b0eeac14 ("target/arm: Allow VFP and Neon to be disabled via a CPU property") we can disable the 'max' cpu model's VFP and neon features, but there's no way to disable SVE. Add the 'sve=on|off' property to give it that flexibility. We also rename cpu_max_get/set_sve_vq to cpu_max_get/set_sve_max_vq in order for them to follow the typical *_get/set_<property-name> pattern.

2019-11-01target/arm/monitor: Introduce qmp_query_cpu_model_expansionAndrew Jones1-0/+146
Add support for the query-cpu-model-expansion QMP command to Arm. We do this selectively, only exposing CPU properties which represent optional CPU features which the user may want to enable/disable. Additionally we restrict the list of queryable cpu models to 'max', 'host', or the current type when KVM is in use. And, finally, we only implement expansion type 'full', as Arm does not yet have a "base" CPU type. More details and example queries are described in a new document (docs/arm-cpu-features.rst). Note, certainly more features may be added to the list of advertised features, e.g. 'vfp' and 'neon'. The only requirement is that we can detect invalid configurations and emit failures at QMP query time. For 'vfp' and 'neon' this will require some refactoring to share a validation function between the QMP query and the CPU realize functions.

2019-10-28target/riscv: PMP violation due to wrong size parameterDayeol Lee1-1/+12
riscv_cpu_tlb_fill() uses the `size` parameter to check PMP violation using pmp_hart_has_privs(). However, if the size is unknown (=0), the ending address will be `addr - 1` as it is `addr + size - 1` in `pmp_hart_has_privs()`. This always causes a false PMP violation on the starting address of the range, as `addr - 1` is not in the range. In order to fix, we just assume that all bytes from addr to the end of the page will be accessed if the size is unknown.
