KVM: selftests: Introduce VM_MODE_PXXV48_4K

2019-09-24T11:37:22Z

The naming VM_MODE_P52V48_4K is explicit but unclear when used on x86_64 machines, because x86_64 machines are having various physical address width rather than some static values. Here's some examples: - Intel Xeon E3-1220: 36 bits - Intel Core i7-8650: 39 bits - AMD EPYC 7251: 48 bits All of them are using 48 bits linear address width but with totally different physical address width (and most of the old machines should be less than 52 bits). Let's create a new guest mode called VM_MODE_PXXV48_4K for current x86_64 tests and make it as the default to replace the old naming of VM_MODE_P52V48_4K because it shows more clearly that the PA width is not really a constant. Meanwhile we also stop assuming all the x86 machines are having 52 bits PA width but instead we fetch the real vm->pa_bits from CPUID 0x80000008 during runtime. We currently make this exclusively used by x86_64 but no other arch. As a slight touch up, moving DEBUG macro from dirty_log_test.c to kvm_util.h so lib can use it too.

KVM: selftests: Split ucall.c into architecture specific files

2019-08-02T13:44:16Z

The way we exit from a guest to userspace is very specific to the architecture: On x86, we use PIO, on aarch64 we are using MMIO and on s390x we're going to use an instruction instead. The possibility to select a type via the ucall_type_t enum is currently also completely unused, so the code in ucall.c currently looks more complex than required. Let's split this up into architecture specific ucall.c files instead, so we can get rid of the #ifdefs and the unnecessary ucall_type_t handling.

kvm: selftests: introduce aarch64_vcpu_add_default

2019-06-05T12:14:45Z

This is the same as vm_vcpu_add_default, but it also takes a kvm_vcpu_init struct pointer. Signed-off-by: Andrew Jones Signed-off-by: Paolo Bonzini

kvm: selftests: introduce aarch64_vcpu_setup

2019-06-05T12:13:38Z

This allows aarch64 tests to run on more targets, such as the Arm simulator that doesn't like KVM_ARM_TARGET_GENERIC_V8. And it also allows aarch64 tests to provide vcpu features in struct kvm_vcpu_init. Additionally it drops the unused memslot parameters. Signed-off-by: Andrew Jones Signed-off-by: Paolo Bonzini

This removes the processor-dependent arguments from vm_vcpu_add. Signed-off-by: Paolo Bonzini

KVM: selftests: Introduce a VM_MODE_DEFAULT macro for the default bits

2019-06-04T12:05:38Z

This will be required later for tests like the kvm_create_max_vcpus test that do not use the vm_create_default() function. Reviewed-by: Andrew Jones Signed-off-by: Thomas Huth Message-Id: <20190523164309.13345-5-thuth@redhat.com> Signed-off-by: Christian Borntraeger

kvm: selftests: aarch64: fix default vm mode

2019-05-24T19:27:16Z

VM_MODE_P52V48_4K is not a valid mode for AArch64. Replace its use in vm_create_default() with a mode that works and represents a good AArch64 default. (We didn't ever see a problem with this because we don't have any unit tests using vm_create_default(), but it's good to get it fixed in advance.)
