2022-02-25KVM: selftests: aarch64: Skip tests if we can't create a vgic-v3Mark Brown1-1/+3
The arch_timer and vgic_irq kselftests assume that they can create a vgic-v3, using the library function vgic_v3_setup() which aborts with a test failure if it is not possible to do so. Since vgic-v3 can only be instantiated on systems where the host has GICv3 this leads to false positives on older systems where that is not the case. Fix this by changing vgic_v3_setup() to return an error if the vgic can't be instantiated and have the callers skip if this happens. We could also exit flagging a skip in vgic_v3_setup() but this would prevent future test cases conditionally deciding which GIC to use or generally doing more complex output.

2020-03-16KVM: selftests: Rework debug message printingAndrew Jones1-1/+1
There were a few problems with the way we output "debug" messages. The first is that we used DEBUG() which is defined when NDEBUG is not defined, but NDEBUG will never be defined for kselftests because it relies too much on assert(). The next is that most of the DEBUG() messages were actually "info" messages, which users may want to turn off if they just want a silent test that either completes or asserts. Finally, a debug message output from a library function, and thus for all tests, was annoying when its information wasn't interesting for a test. Rework these messages so debug messages only output when DEBUG is defined and info messages output unless QUIET is defined. Also name the functions pr_debug and pr_info and make sure that when they're disabled we eat all the inputs. The later avoids unused variable warnings when the variables were only defined for the purpose of printing.

2019-09-24KVM: selftests: Introduce VM_MODE_PXXV48_4KPeter Xu1-0/+3
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.

2019-05-24kvm: selftests: aarch64: fix default vm modeAndrew Jones1-1/+1
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.)

Let's add the 40 PA-bit versions of the VM modes, that AArch64 should have been using, so we can extend the dirty log test without breaking things. Signed-off-by: Andrew Jones <[email protected]> Signed-off-by: Paolo Bonzini <[email protected]>
