Of course more events would have to be added, but\nbefore spending more time on this I'd like to get some feedback on the\ncore of the design. Patch 2 has all the details.\n\nNote: yes, patch 1 is not used in the series, but this is an RFC. It's there\nbecause it will be needed to get the tb->plugin_mask when deciding whether\nto generate a mem_cb helper when generating loads/stores from TCG.\n\nThis set applies on top of:\n https://github.com/cota/qemu/tree/tcg-generic-15%2Bmulti-tcg-v4-parallel\n\nThe tree can be fetched from:\n https://github.com/cota/qemu/tree/plugins\n\nThanks,\n\n\t\tEmilio\n---\n Makefile | 7 +-\n Makefile.objs | 1 +\n accel/tcg/cpu-exec.c | 6 +-\n accel/tcg/translate-all.c | 9 +-\n configure | 52 ++++\n include/exec/exec-all.h | 2 +\n include/exec/tb-hash-xx.h | 26 +-\n include/exec/tb-hash.h | 6 +-\n include/exec/tb-lookup.h | 1 +\n include/qemu/plugin-api.h | 105 +++++++\n include/qemu/plugin.h | 74 +++++\n include/qom/cpu.h | 4 +\n linux-user/main.c | 18 ++\n plugin.c | 519 ++++++++++++++++++++++++++++++++\n qemu-options.hx | 17 ++\n qemu-plugins.symbols | 6 +\n qom/cpu.c | 3 +\n tcg/tcg-op.c | 10 +-\n tcg/tcg.h | 2 +-\n tests/qht-bench.c | 2 +-\n vl.c | 10 +\n 21 files changed, 857 insertions(+), 23 deletions(-)" }
