Isn't this the designware i3c ip block, and as such could we name it so? I was going to send an i2c only version of this but it seems you've beaten me to it and got the i3c core going. > hw/Kconfig | 1 + > hw/arm/Kconfig | 2 + > hw/i3c/Kconfig | 17 + > hw/i3c/aspeed_i3c.c | 2044 +++++++++++++++++++++++++++++++++ > hw/i3c/core.c | 646 +++++++++++ > hw/i3c/meson.build | 6 + > hw/i3c/mock-target.c | 314 +++++ > hw/i3c/remote-i3c.c | 469 ++++++++ > hw/i3c/trace-events | 52 + > hw/i3c/trace.h | 1 + > hw/meson.build | 1 + > hw/misc/aspeed_i3c.c | 384 ------- > hw/misc/meson.build | 1 - > hw/misc/trace-events | 6 - > include/hw/arm/aspeed_soc.h | 2 +- > include/hw/i3c/aspeed_i3c.h | 207 ++++ > include/hw/i3c/i3c.h | 275 +++++ > include/hw/i3c/mock-target.h | 60 + > include/hw/i3c/remote-i3c.h | 72 ++ > include/hw/misc/aspeed_i3c.h | 48 - > meson.build | 1 + > tests/qtest/meson.build | 1 + > tests/qtest/remote-i3c-test.c | 610 ++++++++++ > 23 files changed, 4780 insertions(+), 440 deletions(-) > create mode 100644 hw/i3c/Kconfig > create mode 100644 hw/i3c/aspeed_i3c.c > create mode 100644 hw/i3c/core.c > create mode 100644 hw/i3c/meson.build > create mode 100644 hw/i3c/mock-target.c > create mode 100644 hw/i3c/remote-i3c.c > create mode 100644 hw/i3c/trace-events > create mode 100644 hw/i3c/trace.h > delete mode 100644 hw/misc/aspeed_i3c.c > create mode 100644 include/hw/i3c/aspeed_i3c.h > create mode 100644 include/hw/i3c/i3c.h > create mode 100644 include/hw/i3c/mock-target.h > create mode 100644 include/hw/i3c/remote-i3c.h > delete mode 100644 include/hw/misc/aspeed_i3c.h > create mode 100644 tests/qtest/remote-i3c-test.c > > -- > 2.40.0.348.gf938b09366-goog > > -- Ben Dooks, b...@fluff.org, http://www.fluff.org/ben/ Large Hadron Colada: A large Pina Colada that makes the universe disappear.
