Sync the next stage using the VM before said VM is potentially freed by the TEST_STAGE_HVC_IFACE_FEAT_DISABLED stage. Opportunistically take a double pointer in anticipation of also having to set the new vCPU pointer once the test stops hardcoding '0' everywhere. Signed-off-by:

Rework vcpu_{g,s}et_reg() to provide the APIs that tests actually want to use, and drop the three "one-off" implementations that cropped up due to the poor API. Ignore the handful of direct KVM_{G,S}ET_ONE_REG calls that don't fit the APIs for one reason or another. No functional change intended. Signed-off-by: -

Use a combination of vm_create(), vm_create_with_vcpus(), and vm_vcpu_add() to convert vgic_init from vm_create_default_with_vcpus(), and away from referncing vCPUs by ID. Thus continues the march toward total annihilation of "default" helpers. Signed-off-by:

Convert arch_timer to use vm_create_with_vcpus() and pass around a 'struct kvm_vcpu' object instead of requiring that the index into the array of vCPUs for a given vCPU is also the ID of the vCPU Signed-off-by:

Add a VM creator that "returns" the created vCPUs by filling the provided array. This will allow converting multi-vCPU tests away from hardcoded vCPU IDs. Signed-off-by:

Pass around 'struct kvm_vcpu' objects in hardware_disable_test instead of the VM+vcpu_id (called "index" by the test). Signed-off-by:

Pass around 'struct kvm_vcpu' objects in psci_test instead of relying on global VCPU_IDs. Ideally, the test wouldn't have to manually create vCPUs and thus care about vCPU IDs, but it's not the end of the world and avoiding that behavior isn't guaranteed to be a net positive (an attempt at macro shenanigans did not go very well).

Rework set_boot_cpu_id to pass around 'struct kvm_vcpu' objects instead of relying on global VCPU_IDs. The test is still ugly, but that's unavoidable since the point of the test is to verify that KVM correctly assigns VCPU_ID==0 to be the BSP by default. This is literally one of two KVM selftests that legitimately needs to care about the exact vCPU IDs of the vCPUs it creates. Signed-off-by:

Rename vm_vcpu_add() to __vm_vcpu_add(), and vm_vcpu_add_default() to vm_vcpu_add() to show the relationship between the newly minted vm_vcpu_add() and __vm_vcpu_add(). Signed-off-by:

Return the created 'struct kvm_vcpu' object from vm_vcpu_add_default(), which cleans up a few tests and will eventually allow removing vcpu_get() entirely. Opportunistically rename @vcpuid to @vcpu_id to follow preferred kernel style. Signed-off-by:

Add "arch" into the name of utility functions that are declared in common code, but (surprise!) have arch-specific implementations. Shuffle code around so that all such helpers' declarations are bundled together. Signed-off-by:

An "unrestricted guest" is an VMX-only concept, move the relevant helper to x86-64 code. Assume most readers can correctly convert underscores to spaces and oppurtunistically trim the function comment. Signed-off-by:

Convert vgic_irq to use vm_create_with_one_vcpu() and pass around a 'struct kvm_vcpu' object instead of passing around a vCPU ID (which is always the global VCPU_ID...). Opportunstically align the indentation for multiple functions' parameters. Signed-off-by:

Track the added 'struct kvm_vcpu' object in tsc_scaling_sync instead of relying purely on the VM + vcpu_id combination. Ideally, the test wouldn't need to manually manage vCPUs, but the need to invoke a per-VM ioctl before creating vCPUs is not handled by the selftests framework, at least not yet... Signed-off-by:

Convert dirty_log_test to pass around a 'struct kvm_vcpu' object instead of using a global VCPU_ID. Note, this is a "functional" change in the sense that the test now creates a vCPU with vcpu_id==0 instead of vcpu_id==5. The non-zero VCPU_ID was 100% arbitrary and added little to no validation coverage. If testing non-zero vCPU IDs is desirable for generic tests, that can be done in the future by tweaking the VM creation helpers. The test still hardcodes usage of vcpu_id==0, but only for a few lines. That wart will be removed in the not-too-distant future. Signed-off-by:

Convert debug_regs to use vm_create_with_one_vcpu() and pass around a 'struct kvm_vcpu' object instead of using a global VCPU_ID.
