KVM: selftests: arm64: Determine max ipa size per-page size

2023-11-27T15:03:50Z

We are about to add 52 bit PA guest modes for 4K and 16K pages when the system supports LPA2. In preparation beef up the logic that parses mmfr0 to also tell us what the maximum supported PA size is for each page size. Max PA size = 0 implies the page size is not supported at all.

KVM: selftests: aarch64: vPMU register test for unimplemented counters

2023-10-24T22:59:31Z

Add a new test case to the vpmu_counter_access test to check if PMU registers or their bits for unimplemented counters are not accessible or are RAZ, as expected.

KVM: selftests: Add a helper for SMCCC calls with SMC instruction

2023-04-05T11:07:42Z

Build a helper for doing SMCs in selftests by macro-izing the current HVC implementation and taking the conduit instruction as an argument. Signed-off-by: Oliver Upton Signed-off-by: Marc Zyngier Link: https://lore.kernel.org/r/20230404154050.2270077-13-oliver.upton@linux.dev

KVM: selftests: aarch64: Add aarch64/page_fault_test

2022-11-10T19:10:27Z

Add a new test for stage 2 faults when using different combinations of guest accesses (e.g., write, S1PTW), backing source type (e.g., anon) and types of faults (e.g., read on hugetlbfs with a hole). The next commits will add different handling methods and more faults (e.g., uffd and dirty logging). This first commit starts by adding two sanity checks for all types of accesses: AF setting by the hw, and accessing memslots with holes.

KVM: selftests: aarch64: Construct DEFAULT_MAIR_EL1 using sysreg.h macros

2022-11-10T19:10:27Z

Define macros for memory type indexes and construct DEFAULT_MAIR_EL1 with macros from asm/sysreg.h. The index macros can then be used when constructing PTEs (instead of using raw numbers).

KVM: selftests: aarch64: Add virt_get_pte_hva() library function

2022-11-10T19:10:27Z

Add a library function to get the PTE (a host virtual address) of a given GVA. This will be used in a future commit by a test to clear and check the access flag of a particular page.

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

2022-06-11T15:47:22Z

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

2022-06-11T15:47:10Z

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

KVM: selftests: Return created vcpu from vm_vcpu_add_default()

2022-06-11T15:47:03Z

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
