* qapi: Move qapi-schema.json to qapi/, rename generated filesMarkus Armbruster2018-03-021-2/+1Star
| | | | | | | | | | | | | | | | | | | Move qapi-schema.json to qapi/, so it's next to its modules, and all files get generated to qapi/, not just the ones generated for modules. Consistently name the generated files qapi-MODULE.EXT: qmp-commands.[ch] become qapi-commands.[ch], qapi-event.[ch] become qapi-events.[ch], and qmp-introspect.[ch] become qapi-introspect.[ch]. This gets rid of the temporary hacks in scripts/qapi/commands.py, scripts/qapi/events.py, and scripts/qapi/common.py.

* Include less of the generated modular QAPI headersMarkus Armbruster2018-03-021-1/+1
| | | | | | | | | | | | | | | | | | | | | In my "build everything" tree, a change to the types in qapi-schema.json triggers a recompile of about 4800 out of 5100 objects. The previous commit split up qmp-commands.h, qmp-event.h, qmp-visit.h, qapi-types.h. Each of these headers still includes all its shards. Reduce compile time by including just the shards we actually need. To illustrate the benefits: adding a type to qapi/migration.json now recompiles some 2300 instead of 4800 objects. The next commit will improve it further.

* qapi: Don't special-case simple union wrappersEric Blake2016-03-181-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Simple unions were carrying a special case that hid their 'data' QMP member from the resulting C struct, via the hack method QAPISchemaObjectTypeVariant.simple_union_type(). But by using the work we started by unboxing flat union and alternate branches, coupled with the ability to visit the members of an implicit type, we can now expose the simple union's implicit type in qapi-types.h: | struct q_obj_ImageInfoSpecificQCow2_wrapper { | ImageInfoSpecificQCow2 *data; | }; | | struct q_obj_ImageInfoSpecificVmdk_wrapper { | ImageInfoSpecificVmdk *data; | }; ... | struct ImageInfoSpecific { | ImageInfoSpecificKind type; | union { /* union tag is @type */ | void *data; |- ImageInfoSpecificQCow2 *qcow2; |- ImageInfoSpecificVmdk *vmdk; |+ q_obj_ImageInfoSpecificQCow2_wrapper qcow2; |+ q_obj_ImageInfoSpecificVmdk_wrapper vmdk; | } u; | }; Doing this removes asymmetry between QAPI's QMP side and its C side (both sides now expose 'data'), and means that the treatment of a simple union as sugar for a flat union is now equivalent in both languages (previously the two approaches used a different layer of dereferencing, where the simple union could be converted to a flat union with equivalent C layout but different {} on the wire, or to an equivalent QMP wire form but with different C representation). Using the implicit type also lets us get rid of the simple_union_type() hack. Of course, now all clients of simple unions have to adjust from using su->u.member to using su->u.member.data; while this touches a number of files in the tree, some earlier cleanup patches helped minimize the change to the initialization of a temporary variable rather than every single member access. The generated qapi-visit.c code is also affected by the layout change: |@@ -7393,10 +7393,10 @@ void visit_type_ImageInfoSpecific_member | } | switch (obj->type) { | case IMAGE_INFO_SPECIFIC_KIND_QCOW2: |- visit_type_ImageInfoSpecificQCow2(v, "data", &obj->u.qcow2, &err); |+ visit_type_q_obj_ImageInfoSpecificQCow2_wrapper_members(v, &obj->u.qcow2, &err); | break; | case IMAGE_INFO_SPECIFIC_KIND_VMDK: |- visit_type_ImageInfoSpecificVmdk(v, "data", &obj->u.vmdk, &err); |+ visit_type_q_obj_ImageInfoSpecificVmdk_wrapper_members(v, &obj->u.vmdk, &err); | break; | default: | abort(); Signed-off-by: Eric Blake <eblake@redhat.com> Message-Id: <1458254921-17042-13-git-send-email-eblake@redhat.com> Signed-off-by: Markus Armbruster <armbru@redhat.com>

| | | | | | | | | | | | | | | | | We have two issues with our qapi union layout: 1) Even though the QMP wire format spells the tag 'type', the C code spells it 'kind', requiring some hacks in the generator. 2) The C struct uses an anonymous union, which places all tag values in the same namespace as all non-variant members. This leads to spurious collisions if a tag value matches a non-variant member's name. Make the conversion to the new layout for TPM-related code.

* Use error_is_set() only when necessaryMarkus Armbruster2014-02-171-1/+1
| | | | | | | | | | | | | | | | error_is_set(&var) is the same as var != NULL, but it takes whole-program analysis to figure that out. Unnecessarily hard for optimizers, static checkers, and human readers. Dumb it down to obvious. Gets rid of several dozen Coverity false positives. Note that the obvious form is already used in many places.

* tpm.c: Don't try to put -1 in a variable of type TpmModelPeter Maydell2013-07-291-2/+2
| | | | | | | | | | | | | | | | | | | | | The TpmModel type is an enum (valid values 0 and 1), which means the compiler can legitimately decide that comparisons like 'tpm_models[i] == -1' are never true. (For example it could pick 'unsigned char' as its type for representing the enum.) Avoid this issue by using TPM_MODEL_MAX to mark entries in the tpm_models[] array which aren't filled in, instead of -1. This silences a clang warning: tpm.c:43:27: error: comparison of constant -1 with expression of type 'enum TpmModel' is always false [-Werror,-Wtautological-constant-out-of-range-compare] if (tpm_models[i] == -1) { ~~~~~~~~~~~~~ ^ ~~ Signed-off-by: Peter Maydell <peter.maydell@linaro.org> Message-id: 1375096931-13842-1-git-send-email-peter.maydell@linaro.org Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>

* tpm: reorganize headers and split hardware partPaolo Bonzini2013-04-151-0/+350
The TPM subsystem does not have a full front-end/back-end separation. The sole available backend, tpm_passthrough, depends on the data structures of the sole available frontend, tpm_tis. However, we can at least try to split the user interface (tpm.c) from the implementation (hw/tpm). The patches makes tpm.c not include tpm_int.h, which is shared between tpm_tis.c and tpm_passthrough.c; instead it moves more stuff to tpm_backend.h.
