It tries to allow * many different point-point communications between the message stations on the message ring * and as result is _not_ the best configuration for performance * * The message ring on phoenix family of processors connects the cpus, gmacs, xgmac/spi4, * security engine and the general purpose DMA engines. It provides a high bandwidth, * low latency communication links. On traditional processors, this communication goes through * which inherently does not scale very well with increasing number of cpus. * * Message ring has an in-built flow control mechanism. Every agent/station on the ring has to * have software configured credits to send messages to any agent. Every receiving agent on the * ring has a 256 entry FIFO that can divided into "buckets". All addressing on the ring is * in terms of buckets. There are a total 128 buckets on the ring. The total number of credits * across all sending agents should not exceed the bucket size. * * Below are the receiving agents and the max number of buckets they can have * CPU 0 : 8 buckets * CPU 1 : 8 buckets * * GMAC : 8 buckets * * SEC : 8 buckets * * DMA : 8 buckets * * CMP : Currently disabled. * * The bucket size of a bucket should be aligned to the bucket's starting index in that * receiving station's FIFO. For example, if sizes of bucket0 and bucket1 of a station * are 32 and 32, bucket2's size has to be 64. bucket size 0 is valid. * * The format of the file is pretty straight forward. Each bucket definition has the size * and the list of sending agents to that bucket with the number of credits to send. * * Undefined buckets have a size of 0 and Tx stations have 0 credits to send to that bucket. * * Following are the currently supported bucket names * cpu_0_0 * cpu_0_1 * cpu_0_2 * cpu_0_3 * cpu_0_4 * cpu_0_5 * cpu_0_6 * cpu_0_7 * * cpu_1_0 * cpu_1_1 * cpu_1_2 * cpu_1_3 * cpu_1_4 * cpu_1_5 * cpu_1_6 * cpu_1_7 * * enabled only for xls-b0 * cpu_2_0 * cpu_2_1 * cpu_2_2 * cpu_2_3 * cpu_2_4 * cpu_2_5 * cpu_2_6 * cpu_2_7 * * enabled only for xls-b0 * cpu_3_0 * cpu_3_1 * cpu_3_2 * cpu_3_3 * cpu_3_4 * cpu_3_5 * cpu_3_6 * cpu_3_7 * * gmac0_rfr * gmac0_tx_0 * gmac0_tx_1 * gmac0_tx_2 * gmac0_tx_3 * * gmac1_rfr * gmac1_tx_0 * gmac1_tx_1 * gmac1_tx_2 * gmac1_tx_3 * * sec_pipe_0 * sec_rsa * * Following are the currently supported Tx Agent/Station names * * tx_stn_cpu_0 * tx_stn_cpu_1 * * tx_stn_gmac0 * tx_stn_gmac1 * * tx_stn_dma * * tx_stn_sec * * */ /*************************************************************/ // CPU_0 Message Station bucket "cpu_0_0" { size 32;
