kernel/tools/testing/selftests/kvm/include/aarch64, branch linux-6.2.yHosts the 0x221E linux distro kernel.https://universe.0xinfinity.dev/distro/kernel/atom?h=linux-6.2.y2022-11-10T19:10:27ZKVM: selftests: aarch64: Add aarch64/page_fault_test2022-11-10T19:10:27ZRicardo Kollerricarkol@google.com2022-10-17T19:58:30Zurn:sha1:35c5810157124cb71aaa939cd2d5508192714877
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.

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).

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.

Take a vCPU directly instead of a VM+vcpu pair in all vCPU-scoped helpers
and ioctls.

KVM: selftests: Consolidate KVM_{G,S}ET_ONE_REG helpers2022-06-11T15:47:10ZSean Christophersonseanjc@google.com2022-06-02T00:16:11Zurn:sha1:bfff0f60db89f425920580900ba242df3bd3c652
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.

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
