This patch extends the 'Parent::session()' and 'Root::session()' functions with an additional 'affinity' parameter, which is inteded to express the preferred affinity of the new session. For CPU sessions provided by core, the values will be used to select the set of CPUs assigned to the CPU session. For other services, the session affinity information can be utilized to optimize the locality of the server thread with the client. For example, to enable the IRQ session to route an IRQ to the CPU core on which the corresponding device driver (the IRQ client) is running. |

README
The 'terminal_crosslink' server allows exactly two clients to communicate with each other using the 'Terminal' interface. Data sent to the server gets stored in a buffer of 4096 bytes (one buffer per client). As long as the data to be written fits into the buffer, the 'write()' call returns immediately. If no more data fits into the buffer, the 'write()' call blocks until the other client has consumed some of the data from the buffer via the 'read()' call. The 'read()' call never blocks. A signal receiver can be used to block until new data is ready for reading. Example ------- An example run script 'terminal_crosslink.run' can be found in the 'os/run' directory.
