It continuously move a stream of ETH paquets from the NIC_TX_FIFO (associated to a given NIC channel) to the NIC_TX_QUEUE (associated to the same channel). 183 The NIC_TX_QUEUE implementation depends on the available NIC hardware (it is implemented as a CHBUF for the VciMasterNic component). 184 It blocks if the source TX_FIFO is empty or if the dest TX_QUEUE is full.In this first implementation, the blocking uses a busy-waiting policy, but this should be replaced by a descheduling policy. 185 * '''channel''' : NIC channel index. 186 187 === 9) void '''_sys_nic_rx_move'''( unsigned int channel ) === 188 This function is executed by the NIC_RX kernel thread. It continuously move a stream of ETH paquets from the NIC_RX_QUEUE (associated to a given NIC channel) to several NIC_RX_FIFOs (one per socket). 189 The NIC_RX_QUEUE implementation depends on the available NIC hardware (it is implemented as a CHBUF for the VciMasterNic component). 190 It blocks if the source RX_QUEUE is empty or if the dest TX_FIFO is full. In this first implementation, the blocking uses a busy-waiting policy, but this should be replaced by a descheduling policy. 191 * '''channel''' : NIC channel index. 192 193 == __FBF related syscall handlers__ == 183 194 184 195 === 1) int '''_sys_fbf_size'''( unsigned int* width , unsigned int* height ) === … … 254 265 255 266 256 == Miscelaneous syscall handlers==267 == __Miscelaneous syscall handlers__ == 257 268 258 269 === 1) int '''_sys_ukn'''() ===
