The end result of this series is to have a single definition for\ntarget_info symbol.\n\nThis series adds TargetInfo types in QOM, and retrieve them dynamically(). At\nthe moment, we don't deal yet with multiple TargetInfo selection, but install\nall that is needed to be able to do it easily.\n\nBecause TargetInfo data is set through class_init, it creates an issue at\nstartup, where we may try to instantiate additional (unrelated) types just to\nretrieve the list of \"target-info-X\" types. Those other types class_init may be\nusing target information, to add target specific properties for instance.\nThis issue has been fixed by adding a new object_class_get_list_by_name_prefix\nthat does not force instantiation of all QOM types, but only those matching a\nspecific pattern. This way, we first initialize and retrieve target-info types\nbefore others.\n\nAn alternative would be to leave all this out of QOM, and use startup\ninitializer to add them in a single list. However, because all the single-binary\nwork has been using QOM where possible, it would be really sad to not use it for\nthis final step. Comments are welcome!\n\nFinally, sticking to our promise not create a special \"single-binary\nconfiguration\", the goal is to use the *exact* same codepath for normal binaries\nalso. It means that even for existing system binaries, the goal will be to use\nQOM to retrieve current target, even if there is only one.\n\nv5\n--\n\n- Fix header guard name for target-info-init.h\n (TARGET_INFO_INIT_H -> QEMU_TARGET_INFO_INIT_H)\n- add a new patch to initialize type_table with TYPE_OBJECT and TYPE_INTERFACE,\n as suggested by Richard\n- use a single class_init for all target-info-* classes.\n\nv4\n--\n\n- Revert to v2 MODULE_INIT_TARGET_INFO as Daniel didn't comment on issues about\n about MODULE_INIT_QOM_EARLY.\n\nv3\n--\n\n- fix rebase mistake for one header guard\n- remove MODULE_INIT_TARGET_INFO and introduce MODULE_INIT_QOM_EARLY, as\n requested by Daniel\n\nv2\n--\n\n- fix header guards\n- introduce new module init step (MODULE_INIT_TARGET_INFO)\n- as a consequence of item above, we need to register TYPE_OBJECT before startup\n- fix xtensa core type registration using type_init instead of static ctor\n\nPierrick Bouvier (6):\n qom/object: register OBJECT and INTERFACE QOM types before main\n qom/object: initialize type_table in static ctor with fundamental QOM\n types\n target-info: extract target_info() definition in target-info-init.h\n target-info-qom: detect target from QOM\n target-info: replace target_info() in system-mode\n target-info-qom: use a single class_init for target-info-* classes\n\n configs/targets/aarch64-softmmu.c | 6 +--\n configs/targets/arm-softmmu.c | 6 +--\n include/qemu/module.h | 1 +\n include/qemu/target-info-init.h | 63 +++++++++++++++++++++++++++++++\n include/qemu/target-info-qom.h | 31 +++++++++++++++\n qom/object.c | 22 +++--------\n system/vl.c | 4 ++\n target-info-qom.c | 41 ++++++++++++++++++++\n target-info-stub.c | 6 +--\n 9 files changed, 152 insertions(+), 28 deletions(-)\n create mode 100644 include/qemu/target-info-init.h\n create mode 100644 include/qemu/target-info-qom.h" }
