A system and a method are disclosed for an intra-panel communication interface which, among other advantages, enhances system reliability and reduces bus width. A timing controller initializes communication with a plurality of source drivers by transmitting link data through a plurality of data channels and monitors source driver status through an auxiliary status channel. The plurality of source drivers share the auxiliary status channel to indicate their status. The timing controller transmits display data to a source driver through a data channel. The display data includes a request for status data from the source driver. The source driver transmits the requested status data to the timing controller via the auxiliary status channel.

Scalable intra-panel interface

A software reload is executed. The hardware associated with the network device continues to forward network traffic during the software reload. Also, a kernel of the network device operates unaffected in a protected address space throughout the software reload. Further, the kernel preserves local checkpointed and shared memory data. Application processes running on the network node are shut down gracefully. The reloaded software is brought up and the network device is resynchronized.
