| H A D | arm_ffa.h | 02c19d84 Wed Apr 17 09:09:31 GMT 2024 Sudeep Holla <[email protected]> firmware: arm_ffa: Add support for FFA_MSG_SEND2
The FFA_MSG_SEND2 can be used to transmit a partition message from
the Tx buffer of the sender(the driver in this case) endpoint to the Rx
buffer of the receiver endpoint.
An invocation of the FFA_MSG_SEND2 transfers the ownership of the Tx
buffer to the receiver endpoint(or any intermediate consumer). Completion
of an FFA_MSG_SEND2 invocation transfers the ownership of the buffer
back to the sender endpoint.
The framework defines the FFA_MSG_SEND2 interface to transmit a partition
message from the Tx buffer of the sender to the Rx buffer of a receiver
and inform the scheduler that the receiver must be run.
