After this series is merged I'll send a series that - removes unnecessary includes from kvm_util_common.h and other headers - renames kvm_util.h to libkvm.h - also includes guest_modes.h and test_util.h from libkvm.h - simplify the includes of all unit tests since they'll be including libkvm.h - probably move include/sparsebit.h to lib, since no unit test needs it Thanks, drew > diff --git a/tools/testing/selftests/kvm/include/kvm_util_base.h b/tools/testing/selftests/kvm/include/kvm_util_base.h > index 8fb6aeff5469..4e2946ba3ff7 100644 > --- a/tools/testing/selftests/kvm/include/kvm_util_base.h > +++ b/tools/testing/selftests/kvm/include/kvm_util_base.h > @@ -360,55 +360,6 @@ int vm_create_device(struct kvm_vm *vm, struct kvm_create_device *cd); > > void assert_on_unhandled_exception(struct kvm_vm *vm, uint32_t vcpuid); > > -/* Common ucalls */ > -enum { > - UCALL_NONE, > - UCALL_SYNC, > - UCALL_ABORT, > - UCALL_DONE, > - UCALL_UNHANDLED, > -}; > - > -#define UCALL_MAX_ARGS 6 > - > -struct ucall { > - uint64_t cmd; > - uint64_t args[UCALL_MAX_ARGS]; > -}; > - > -void ucall_init(struct kvm_vm *vm, void *arg); > -void ucall_uninit(struct kvm_vm *vm); > -void ucall(uint64_t cmd, int nargs, ...); > -uint64_t get_ucall(struct kvm_vm *vm, uint32_t vcpu_id, struct ucall *uc); > - > -#define GUEST_SYNC_ARGS(stage, arg1, arg2, arg3, arg4) \ > - ucall(UCALL_SYNC, 6, "hello", stage, arg1, arg2, arg3, arg4) > -#define GUEST_SYNC(stage) ucall(UCALL_SYNC, 2, "hello", stage) > -#define GUEST_DONE() ucall(UCALL_DONE, 0) > -#define __GUEST_ASSERT(_condition, _condstr, _nargs, _args...) do { \ > - if (!(_condition)) \ > - ucall(UCALL_ABORT, 2 + _nargs, \ > - "Failed guest assert: " \ > - _condstr, __LINE__, _args); \ > -} while (0) > - > -#define GUEST_ASSERT(_condition) \ > - __GUEST_ASSERT(_condition, #_condition, 0, 0) > - > -#define GUEST_ASSERT_1(_condition, arg1) \ > - __GUEST_ASSERT(_condition, #_condition, 1, (arg1)) > - > -#define GUEST_ASSERT_2(_condition, arg1, arg2) \ > - __GUEST_ASSERT(_condition, #_condition, 2, (arg1), (arg2)) > - > -#define GUEST_ASSERT_3(_condition, arg1, arg2, arg3) \ > - __GUEST_ASSERT(_condition, #_condition, 3, (arg1), (arg2), (arg3)) > - > -#define GUEST_ASSERT_4(_condition, arg1, arg2, arg3, arg4) \ > - __GUEST_ASSERT(_condition, #_condition, 4, (arg1), (arg2), (arg3), (arg4)) > - > -#define GUEST_ASSERT_EQ(a, b) __GUEST_ASSERT((a) == (b), #a " == " #b, 2, a, b) > - > int vm_get_stats_fd(struct kvm_vm *vm); > int vcpu_get_stats_fd(struct kvm_vm *vm, uint32_t vcpuid); > > diff --git a/tools/testing/selftests/kvm/include/ucall_common.h b/tools/testing/selftests/kvm/include/ucall_common.h > new file mode 100644 > index 000000000000..9eecc9d40b79 > --- /dev/null > +++ b/tools/testing/selftests/kvm/include/ucall_common.h > @@ -0,0 +1,59 @@ > +/* SPDX-License-Identifier: GPL-2.0-only */ > +/* > + * tools/testing/selftests/kvm/include/kvm_util.h > + * > + * Copyright (C) 2018, Google LLC. > + */ > +#ifndef SELFTEST_KVM_UCALL_COMMON_H > +#define SELFTEST_KVM_UCALL_COMMON_H > + > +/* Common ucalls */ > +enum { > + UCALL_NONE, > + UCALL_SYNC, > + UCALL_ABORT, > + UCALL_DONE, > + UCALL_UNHANDLED, > +}; > + > +#define UCALL_MAX_ARGS 6 > + > +struct ucall { > + uint64_t cmd; > + uint64_t args[UCALL_MAX_ARGS]; > +}; > + > +void ucall_init(struct kvm_vm *vm, void *arg); > +void ucall_uninit(struct kvm_vm *vm); > +void ucall(uint64_t cmd, int nargs, ...); > +uint64_t get_ucall(struct kvm_vm *vm, uint32_t vcpu_id, struct ucall *uc); > + > +#define GUEST_SYNC_ARGS(stage, arg1, arg2, arg3, arg4) \ > + ucall(UCALL_SYNC, 6, "hello", stage, arg1, arg2, arg3, arg4) > +#define GUEST_SYNC(stage) ucall(UCALL_SYNC, 2, "hello", stage) > +#define GUEST_DONE() ucall(UCALL_DONE, 0) > +#define __GUEST_ASSERT(_condition, _condstr, _nargs, _args...) do { \ > + if (!(_condition)) \ > + ucall(UCALL_ABORT, 2 + _nargs, \ > + "Failed guest assert: " \ > + _condstr, __LINE__, _args); \ > +} while (0) > + > +#define GUEST_ASSERT(_condition) \ > + __GUEST_ASSERT(_condition, #_condition, 0, 0) > + > +#define GUEST_ASSERT_1(_condition, arg1) \ > + __GUEST_ASSERT(_condition, #_condition, 1, (arg1)) > + > +#define GUEST_ASSERT_2(_condition, arg1, arg2) \ > + __GUEST_ASSERT(_condition, #_condition, 2, (arg1), (arg2)) > + > +#define GUEST_ASSERT_3(_condition, arg1, arg2, arg3) \ > + __GUEST_ASSERT(_condition, #_condition, 3, (arg1), (arg2), (arg3)) > + > +#define GUEST_ASSERT_4(_condition, arg1, arg2, arg3, arg4) \ > + __GUEST_ASSERT(_condition, #_condition, 4, (arg1), (arg2), (arg3), (arg4)) > + > +#define GUEST_ASSERT_EQ(a, b) __GUEST_ASSERT((a) == (b), #a " == " #b, 2, a, b) > + > +#endif /* SELFTEST_KVM_UCALL_COMMON_H */ > -- > 2.25.1 >
