KVM: selftests: Purge vm+vcpu_id == vcpu silliness

2022-06-11T15:47:22+00:00

Take a vCPU directly instead of a VM+vcpu pair in all vCPU-scoped helpers and ioctls. Signed-off-by: Sean Christopherson Signed-off-by: Paolo Bonzini

KVM: selftests: Consolidate KVM_{G,S}ET_ONE_REG helpers

2022-06-11T15:47:10+00:00

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.

KVM: selftests: Rename vm_vcpu_add* helpers to better show relationships

2022-06-11T15:47:04+00:00

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: Sean Christopherson Signed-off-by: Paolo Bonzini

KVM: selftests: Return created vcpu from vm_vcpu_add_default()

2022-06-11T15:47:03+00:00

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: Sean Christopherson Signed-off-by: Paolo Bonzini

KVM: selftests: Make arm64's guest_get_vcpuid() declaration arm64-only

2022-06-11T15:47:02+00:00

Move the declaration of guest_get_vcpuid() to include/aarch64/processor.h, it is implemented and used only by arm64. Signed-off-by: Sean Christopherson Signed-off-by: Paolo Bonzini

selftests: KVM: Create helper for making SMCCC calls

2022-05-03T20:30:20+00:00

The PSCI and PV stolen time tests both need to make SMCCC calls within the guest. Create a helper for making SMCCC calls and rework the existing tests to use the library function.

KVM: selftests: arm64: Check for supported page sizes

2021-12-28T11:04:20+00:00

Just as arm64 implemenations don't necessary support all IPA ranges, they don't all support the same page sizes either. Fun. Create a dummy VM to snapshot the page sizes supported by the host, and filter the supported modes.

KVM: arm64: selftests: Maintain consistency for vcpuid type

2021-10-17T10:17:21+00:00

The prototype of aarch64_vcpu_setup() accepts vcpuid as 'int', while the rest of the aarch64 (and struct vcpu) carries it as 'uint32_t'. Hence, change the prototype to make it consistent throughout the board.

KVM: arm64: selftests: Add support to disable and enable local IRQs

2021-10-17T10:17:20+00:00

Add functions local_irq_enable() and local_irq_disable() to enable and disable the IRQs from the guest, respectively.

KVM: arm64: selftests: Add support for cpu_relax

2021-10-17T10:17:20+00:00

Implement the guest helper routine, cpu_relax(), to yield the processor to other tasks. The function was derived from arch/arm64/include/asm/vdso/processor.h.
