Aspeed 2600 SDK enables I3C support by default. The I3C driver will try to reset the device controller and setup through device address table register. This dummy model response these register with default value listed on ast2600v10 datasheet chapter 54.2. If the device address table register doesn't set correctly, it will cause guest machine kernel panic due to reference to invalid address. v2: - Split i3c model into i3c and i3c_device - Create 6x i3c devices - Using register fields macro Signed-off-by: Troy Lee --- hw/misc/aspeed_i3c.c | 410 +++++++++++++++++++++++++++++++++++ hw/misc/meson.build | 1 + hw/misc/trace-events | 6 + include/hw/misc/aspeed_i3c.h | 57 +++++ 4 files changed, 474 insertions(+) create mode 100644 hw/misc/aspeed_i3c.c create mode 100644 include/hw/misc/aspeed_i3c.h diff --git a/hw/misc/aspeed_i3c.c b/hw/misc/aspeed_i3c.c new file mode 100644 index 0000000000..16a4f2d4e4 --- /dev/null +++ b/hw/misc/aspeed_i3c.c @@ -0,0 +1,410 @@ +/* + * ASPEED I3C Controller + * + * Copyright (C) 2021 ASPEED Technology Inc. + * + * This code is licensed under the GPL version 2 or later.
