This patch series adds support for module meta-data. Today this is either hard-coded in qemu (see qemu_load_module_for_opts) or handled with manually maintained lists in util/module (see module_deps[] and qom_modules[]). This series replaced that scheme with annotation macros, so the meta-data can go into the module source code and -- for example -- the module_obj() annotations can go next to the TypeInfo struct for the object class.
Patches 1-3 put the infrastructure in place: Add the annotation macros, add a script to collect the meta-data, add a script to compile the meta-data into C source code which we can then add to qemu. Patches 4-12 add annotations macros to the modules we have. Patches 13-15 put the modinfo database into use and remove the module_deps[] and qom_modules[] lists. Patch 16 adds two tracepoints for easier trouble-shooting. Patches 17-19 add support for target-specific modules. Patches 20-14 start building accelerators modular. So far it is only qtest (all archs) and a small fraction of tcg (x86 only). take care, Gerd Gerd Hoffmann (24): modules: add modinfo macros modules: collect module meta-data modules: generate modinfo.c modules: add qxl module annotations modules: add virtio-gpu module annotations modules: add chardev module annotations modules: add audio module annotations modules: add usb-redir module annotations modules: add ccid module annotations modules: add ui module annotations modules: add s390x module annotations modules: add block module annotations modules: use modinfo for dependencies modules: use modinfo for qom load modules: use modinfo for qemu opts load modules: add tracepoints modules: check arch and block load on mismatch modules: check arch on qom lookup modules: target-specific module build infrastructure accel: autoload modules accel: add qtest module annotations accel: build qtest modular accel: add tcg module annotations accel: build tcg modular scripts/modinfo-collect.py | 67 +++++++++++ scripts/modinfo-generate.py | 84 ++++++++++++++ include/qemu/module.h | 43 +++++++ accel/accel-common.c | 2 +- accel/accel-softmmu.c | 2 +- accel/qtest/qtest.c | 2 + accel/tcg/tcg-accel-ops.c | 1 + accel/tcg/tcg-all.c | 1 + audio/spiceaudio.c | 2 + block/iscsi-opts.c | 1 + chardev/baum.c | 1 + chardev/spice.c | 4 + hw/display/qxl.c | 4 + hw/display/vhost-user-gpu-pci.c | 1 + hw/display/vhost-user-gpu.c | 1 + hw/display/vhost-user-vga.c | 1 + hw/display/virtio-gpu-base.c | 1 + hw/display/virtio-gpu-gl.c | 3 + hw/display/virtio-gpu-pci-gl.c | 3 + hw/display/virtio-gpu-pci.c | 2 + hw/display/virtio-gpu.c | 1 + hw/display/virtio-vga-gl.c | 3 + hw/display/virtio-vga.c | 2 + hw/s390x/virtio-ccw-gpu.c | 3 + hw/usb/ccid-card-emulated.c | 1 + hw/usb/ccid-card-passthru.c | 1 + hw/usb/redirect.c | 1 + softmmu/vl.c | 24 ++-- stubs/module-opts.c | 4 - ui/egl-headless.c | 4 + ui/gtk.c | 4 + ui/sdl2.c | 4 + ui/spice-app.c | 3 + ui/spice-core.c | 5 + util/module.c | 200 ++++++++++++++++++-------------- accel/qtest/meson.build | 8 +- accel/tcg/meson.build | 5 +- meson.build | 76 ++++++++++++ util/trace-events | 4 + 39 files changed, 462 insertions(+), 117 deletions(-) create mode 100755 scripts/modinfo-collect.py create mode 100755 scripts/modinfo-generate.py -- 2.31.1
