We just have to provide some stubs for linking the code from kvm_util.c. Note that you also might have to do "ulimit -n 2500" before running the test, to avoid that it runs out of file handles for the vCPUs. Signed-off-by: Thomas Huth --- RFC since the stubs are a little bit ugly (does someone here like to implement them?), and since it's a little bit annoying that you have to raise the ulimit for this test in case the kernel provides more vCPUs than the default ulimit... tools/testing/selftests/kvm/Makefile | 6 +++ .../selftests/kvm/lib/powerpc/processor.c | 37 +++++++++++++++++++ 2 files changed, 43 insertions(+) create mode 100644 tools/testing/selftests/kvm/lib/powerpc/processor.c diff --git a/tools/testing/selftests/kvm/Makefile b/tools/testing/selftests/kvm/Makefile index ba7849751989..c92dc78ff74b 100644 --- a/tools/testing/selftests/kvm/Makefile +++ b/tools/testing/selftests/kvm/Makefile @@ -11,6 +11,8 @@ LIBKVM = lib/assert.c lib/elf.c lib/io.c lib/kvm_util.c lib/ucall.c lib/sparsebi LIBKVM_x86_64 = lib/x86_64/processor.c lib/x86_64/vmx.c LIBKVM_aarch64 = lib/aarch64/processor.c LIBKVM_s390x = lib/s390x/processor.c +LIBKVM_ppc64 = lib/powerpc/processor.c +LIBKVM_ppc64le = $(LIBKVM_ppc64) TEST_GEN_PROGS_x86_64 = x86_64/cr4_cpuid_sync_test TEST_GEN_PROGS_x86_64 += x86_64/evmcs_test @@ -35,6 +37,10 @@ TEST_GEN_PROGS_aarch64 += kvm_create_max_vcpus TEST_GEN_PROGS_s390x += s390x/sync_regs_test TEST_GEN_PROGS_s390x += kvm_create_max_vcpus +TEST_GEN_PROGS_ppc64 += kvm_create_max_vcpus + +TEST_GEN_PROGS_ppc64le = $(TEST_GEN_PROGS_ppc64) + TEST_GEN_PROGS += $(TEST_GEN_PROGS_$(UNAME_M)) LIBKVM += $(LIBKVM_$(UNAME_M)) diff --git a/tools/testing/selftests/kvm/lib/powerpc/processor.c b/tools/testing/selftests/kvm/lib/powerpc/processor.c new file mode 100644 index 000000000000..c0b7f06e206e --- /dev/null +++ b/tools/testing/selftests/kvm/lib/powerpc/processor.c @@ -0,0 +1,37 @@ +// SPDX-License-Identifier: GPL-2.0-only +/* + * KVM selftest s390x library code - CPU-related functions + */ + +#define _GNU_SOURCE + +#include "kvm_util.h" +#include "../kvm_util_internal.h" + +void virt_pgd_alloc(struct kvm_vm *vm, uint32_t memslot) +{ + abort(); /* TODO: implement this */ +} + +void virt_pg_map(struct kvm_vm *vm, uint64_t gva, uint64_t gpa, + uint32_t memslot) +{ + abort(); /* TODO: implement this */ +} + +vm_paddr_t addr_gva2gpa(struct kvm_vm *vm, vm_vaddr_t gva) +{ + abort(); /* TODO: implement this */ + + return -1; +} + +void virt_dump(FILE *stream, struct kvm_vm *vm, uint8_t indent) +{ + abort(); /* TODO: implement this */ +} + +void vcpu_dump(FILE *stream, struct kvm_vm *vm, uint32_t vcpuid, uint8_t indent) +{ + abort(); /* TODO: implement this */ +}
