Hi, I'd like to compare the performance of two different synchronous data transfer mechanisms:
* Copies * Page maps / unmaps For the second one, it looks like I can use the streammap example (pkg/examples/libs/l4re/streammap), although I'm lacking a mechanism to unmap the page before returning control to the client. It would also be nice to be able to pass the server a read-only region. For the first one, I've only found the use of multiple send/recv operations through the limited amount of data available on the message registers. There is a "Gen_string" class in the "ipc_stream" header, which looks like it could support offline string transfers, but it's disabled at compile time and I could not find the actual code in fiasco that handles these transfers.
