/*
|
|
The IPC registers are connected to each other.
|
|
Both registers are identical and this works for
|
|
both peers. Flag bits are cleared by writing a one
|
|
to them.
|
|
|
|
When Peer A sets this Peer B sees this set
|
|
IPC_CTRL_SEND IPC_CTRL_RECV
|
|
IPC_CTRL_RECVD IPC_CTRL_SENT
|
|
|
|
In fact, bit _SEND on Peer A and bit _RECV on peer B are the same bit,
|
|
and the same goes for _RECVD and _SENT, except writing one from A _sets_
|
|
the bit, and writing one from B _clears_ the bit. The same, of course,
|
|
is true for the other pair of bits in the other direction.
|
|
|
|
The flow, therefore, goes as follows, for a message
|
|
from A to B. Steps with the same number can be taken
|
|
in any order.
|
|
|
|
1. Peer A writes the message address to the register
|
|
2. Peer A sets IPC_CTRL_SEND
|
|
3. Peer B sees IPC_CTRL_RECV
|
|
4. Peer B writes one to IPC_CTRL_RECV to clear it (A's IPC_CTRL_SEND is cleared at this point)
|
|
4. Peer B reads its message address register
|
|
5. Peer B sets IPC_CTRL_RECVD
|
|
6. Peer A sees IPC_CTRL_SENT
|
|
7. Peer A writes one to IPC_CTRL_SENT to clear it (B's IPC_CTRL_RECVD is cleared at this point)
|
|
7. Peer A may now write to the message address register again
|
|
|
|
The same is true for a message from Peer B to Peer A.
|
|
|
|
In the particular case of IOS IPC, the PPC is always the "master"
|
|
(it sends requests as messages) and the ARM is always the "slave"
|
|
(it replies to PPC's requests). IOS can handle up to 16(15?)
|
|
simultaneously pending transactions (the PPC can send up to 16(15?)
|
|
messages without getting any replies - for example, due to
|
|
asynchronous requests or multithreaded execution of blocking
|
|
requests)
