KVM: selftests: riscv: Fix alignment of the guest_hang() function

2022-04-20T07:36:14Z

[ Upstream commit ebdef0de2dbc40e697adaa6b3408130f7a7b8351 ] The guest_hang() function is used as the default exception handler for various KVM selftests applications by setting it's address in the vstvec CSR. The vstvec CSR requires exception handler base address to be at least 4-byte aligned so this patch fixes alignment of the guest_hang() function.

KVM: selftests: Add initial support for RISC-V 64-bit

2022-01-06T09:47:50Z

We add initial support for RISC-V 64-bit in KVM selftests using which we can cross-compile and run arch independent tests such as: demand_paging_test dirty_log_test kvm_create_max_vcpus, kvm_page_table_test set_memory_region_test kvm_binary_stats_test All VM guest modes defined in kvm_util.h require at least 48-bit guest virtual address so to use KVM RISC-V selftests hardware need to support at least Sv48 MMU for guest (i.e. VS-mode).
