hw/i3c: remote_i3c: Add model
Adds a model to communicate to remote I3C devices over chardev. This
allows QEMU to communicate to I3C targets that exist outside of QEMU.
The remote I3C protocol is a
hw/i3c: remote_i3c: Add model
Adds a model to communicate to remote I3C devices over chardev. This
allows QEMU to communicate to I3C targets that exist outside of QEMU.
The remote I3C protocol is as follows:
On an I3C private and CCC TX (controller -> target)
- 1-byte opcode
- 4-byte number of bytes in the packet as a LE uint32
- n-byte payload
On an I3C private and CCC RX (target -> controller)
Controller to target:
- 1-byte opcode
- 4-byte number of bytes to read as a LE uint32
Remote target response:
- 4-byte number of bytes in the packet as a LE uint32
- n-byte payload
IBI (target -> controller, initiated by target)
- 1-byte opcode
- 1-byte IBI address
- 1-byte RnW boolean
- 4-byte length of IBI payload from target as a LE uint32 (can be 0)
- n-byte IBI payload
