KVM: riscv: selftests: Fix get-reg-list print_reg defaults

2023-12-13T06:25:15+00:00

print_reg() will print everything it knows when it encounters a register ID it's unfamiliar with in the default cases of its decoding switches. Fix several issues with these (until now, never tested) paths; missing newlines in printfs, missing complement operator in mask, and missing return in order to avoid continuing to decode.

KVM: riscv: selftests: Add SBI DBCN extension to get-reg-list test

We have a new SBI debug console (DBCN) extension supported by in-kernel KVM so let us add this extension to get-reg-list test. Signed-off-by: Anup Patel Reviewed-by: Andrew Jones Signed-off-by: Anup Patel

KVM: riscv: selftests: get-reg-list print_reg should never fail

2023-10-12T13:14:37+00:00

When outputting the "new" register list we want to print all of the new registers, decoding as much as possible of each of them. Also, we don't want to assert while listing registers with '--list'. We output "/* UNKNOWN */" after each new register (which we were already doing for some), which should be enough. Signed-off-by: Andrew Jones Reviewed-by: Haibo Xu Signed-off-by: Anup Patel

KVM: selftests: Add array order helpers to riscv get-reg-list

2023-10-12T13:14:18+00:00

Add a couple macros to use when filling arrays in order to ensure the elements are placed in the right order, regardless of the order we prefer to read them. And immediately apply the new macro to resorting the ISA extension lists alphabetically. Signed-off-by: Andrew Jones Reviewed-by: Haibo Xu Signed-off-by: Anup Patel

KVM: riscv: selftests: Selectively filter-out AIA registers

2023-09-21T09:34:05+00:00

Currently the AIA ONE_REG registers are reported by get-reg-list as new registers for various vcpu_reg_list configs whenever Ssaia is available on the host because Ssaia extension can only be disabled by Smstateen extension which is not always available. To tackle this, we should filter-out AIA ONE_REG registers only when Ssaia can't be disabled for a VCPU.

KVM: riscv: selftests: Fix ISA_EXT register handling in get-reg-list

2023-09-21T09:34:03+00:00

Same set of ISA_EXT registers are not present on all host because ISA_EXT registers are visible to the KVM user space based on the ISA extensions available on the host. Also, disabling an ISA extension using corresponding ISA_EXT register does not affect the visibility of the ISA_EXT register itself. Based on the above, we should filter-out all ISA_EXT registers.
