Statistics values are accessed ++through the @c Control() interface of the CPHAL. There are 5 different levels ++of statistics, each of which correspond to a unique set of data. Furthermore, ++certain statistics data is indexed by using a channel number and Tx queue number. ++The following is a brief description of each statistics level, along with the ++indexes used for the level: ++ ++- Level 0: Hardware Statistics (index with channel) ++- Level 1: CPHAL Software Statistics (channel, queue) ++- Level 2: CPHAL Flags (channel, queue) ++- Level 3: CPHAL Channel Configuration (channel) ++- Level 4: CPHAL General Configuration (no index) ++ ++The caller requests statistics information by providing a Key string to the ++@c Control() API in the following format: "Stats;[Level #];[Ch #];[Queue #]". ++The only valid Action parameter for statistics usage is "Get". ++ ++Code Examples: ++@code ++unsigned int *StatsData; ++ ++# Get Level 0 stats for Channel 1 ++HalFunc->Control(OsDev->HalDev, "Stats;0;1", "Get", &StatsData); ++ ++# Get Level 2 stats for Channel 0, Queue 0 ++HalFunc->Control(OsDev->HalDev, "Stats;2;0;0", "Get", &StatsData); ++ ++# Get Level 4 stats ++HalFunc->Control(OsDev->HalDev, "Stats;4", "Get", &StatsData); ++@endcode ++ ++The information returned in the Value parameter of @c Control() is an ++array of pointers to strings. The pointers are arranged in pairs. ++The first pointer is a pointer to a name string for a particular statistic. ++The next pointer is a pointer to a string containing the representation of ++the integer statistic value corresponding to the first pointer. This is followed ++by another pair of pointers, and so on, until a NULL pointer is encountered. The ++following is example code for processing the statistics data. Note that the OS ++is responsible for freeing the memory passed back through the Value parameter of ++@c Control(). ++ ++@code ++unsigned int *StatsData; ++ ++# Get Level 0 stats for Channel 1 ++HalFunc->Control(OsDev->HalDev, "Stats;0;1", "Get", &StatsData); ++ ++# output Statistics data ++PrintStats(StatsData); ++ ++# the upper layer is responsible for freeing stats info ++free(&StatsPtr); ++ ++... ++ ++void PrintStats(unsigned int *StatsPtr) ++ { ++ while(*StatsPtr) ++ { ++ printf("%20s:", (char *)*StatsPtr); ++ StatsPtr++; ++ printf("%11s\n", (char *)*StatsPtr); ++ StatsPtr++; ++ } ++ MySioFlush(); ++ } ++@endcode ++ ++Within each statistics level, there are several statistics defined. The statistics that ++are common to every CPPI module are listed below. In addition, each module may define ++extra statistics in each level, which will be documented within the module-specific ++documentation appendices. ++ ++- Level 0 Statistics ++ - All level 0 statistics are module-specific. ++- Level 1 Statistics (CPHAL Software Statistics) ++ - DmaLenErrors: Incremented when the port DMA's more data than expected (per channel). (AAL5 Only) ++ - TxMisQCnt: Incremented when host queues a packet for transmission as the port finishes ++transmitting the previous last packet in the queue (per channel and queue). ++ - RxMisQCnt: Incremented when host queues adds buffers to a queue as the port finished the ++reception of the previous last packet in the queue (per channel). ++ - TxEOQCnt: Number of times the port has reached the end of the transmit queue (per channel and queue). ++ - RxEOQCnt: Number of times the port has reached the end of the receive queue (per channel). ++ - RxPacketsServiced: Number of received packets (per channel). ++ - TxPacketsServiced: Number of transmitted packets (per channel and queue). ++ - RxMaxServiced: Maximum number of packets that the CPHAL receive interrupt has serviced at a time (per channel). ++ - TxMaxServiced: Maximum number of packets that the CPHAL transmit interrupt has serviced at a time (per channel and queue). ++ - RxTotal: Total number of received packets, all channels. ++ - TxTotal: Total number of transmitted packets, all channels and queues. ++- Level 2 Statistics (CPHAL Flags) ++ - RcbPool: Pointer to receive descriptor pool (per channel). ++ - RxActQueueCount: Number of buffers currently available for receive (per channel). ++ - RxActQueueHead: Pointer to first buffer in receive queue (per channel). ++ - RxActQueueTail: Pointer to last buffer in receive queue (per channel). ++ - RxActive: 0 if inactive (no buffers available), or 1 if active (buffers available). ++ - RcbStart: Pointer to block of receive descriptors. ++ - RxTeardownPending: 1 if Rx teardown is pending but incomplete, 0 otherwise. ++ - TcbPool: Pointer to transmit descriptor pool (per channel and queue). ++ - TxActQueueCount: Number of buffers currently queued to be transmitted (per channel and queue). ++ - TxActQueueHead: Pointer to first buffer in transmit queue (per channel and queue). ++ - TxActQueueTail: Pointer to last buffer in transmit queue (per channel and queue). ++ - TxActive: 0 if inactive (no buffers to send), or 1 if active (buffers queued to send). ++ - TcbStart: Pointer to block of transmit descriptors. ++ - TxTeardownPending: 1 if Tx teardown is pending but incomplete, 0 otherwise. ++- Level 3 Statistics (CPHAL Channel Configuration) ++ - RxBufSize: Rx buffer size. ++ - RxBufferOffset: Rx buffer offset. ++ - RxNumBuffers: Number of Rx buffers. ++ - RxServiceMax: Maximum number of receive packets to service at a time. ++ - TxNumBuffers: Number of Tx buffer descriptors. ++ - TxNumQueues: Number of Tx queues to use. ++ - TxServiceMax: Maximum number of transmit packets to service at a time. ++- Level 4 Statistics (CPHAL General Configuration) ++ - Base Address: Base address of the module. ++ - Offset (VLYNQ): VLYNQ relative module offset. ++ - Interrupt Line: Interrupt number. ++ - Debug: Debug flag, 1 to enable debug. ++ - Inst: Instance number. ++*/ ++ ++/* ++ Data Type 0 = int display ++ Data Type 1 = hex display ++ Data Type 2 = channel structure, int display ++ Data Type 3 = queue index and int display ++ Data Type 4 = queue index and hex display ++*/ ++#if (defined(_CPHAL_AAL5) || defined(_CPHAL_CPMAC)) /* +GSG 030307 */ ++static STATS_TABLE StatsTable0[] = ++ { ++#ifdef _CPHAL_AAL5 ++ /* Name , Data Ptr, Data Type */ ++ {"Crc Errors", 0, 0}, ++ {"Len Errors", 0, 0}, ++ {"Abort Errors", 0, 0}, ++ {"Starv Errors", 0, 0} ++#endif ++#ifdef _CPHAL_CPMAC ++ {"Rx Good Frames", 0, 0} ++#endif ++ };
