Additionally and independent of wrapping, tracing can be temporarily enabled and disabled * by the tracing triggers. All XMC commands can be traced except for IDLE and IOBRSP. The subset of XMC * commands that are traced is determined by the filter and the two triggers, each of which is comprised of * masks for command, sid, did, and address). If triggers are disabled, then only those commands matching * the filter are traced. If triggers are enabled, then only those commands matching the filter, the start * trigger, or the stop trigger are traced during the time between a start trigger and a stop trigger. * * For a given command, its XMC data is written immediately to the buffer. If the command has XMD data, * then that data comes in-order at some later time. The XMD data is accumulated across all valid * XMD cycles and written to the buffer or to a shallow fifo. Data from the fifo is written to the buffer * as soon as it gets access to write the buffer (i.e. the buffer is not currently being written with XMC * data). If the fifo overflows, it simply overwrites itself and the previous XMD data is lost. * * * READING THE TRACE BUFFER * * Each entry of the trace buffer is read by a CSR read command. The trace buffer services each read in order, * as soon as it has access to the (single-ported) trace buffer. * * On Octeon2, each entry of the trace buffer is read by two CSR memory read operations. The first read accesses * bits 63:0 of the buffer entry, and the second read accesses bits 68:64 of the buffer entry. The trace buffer * services each read in order, as soon as it has access to the (single-ported) trace buffer. Buffer's read pointer * increments after two CSR memory read operations. * * * OVERFLOW, UNDERFLOW AND THRESHOLD EVENTS * * The trace buffer maintains a write pointer and a read pointer and detects both the overflow and underflow * conditions. Each time a new trace is enabled, both pointers are reset to entry 0. Normally, each write * (traced event) increments the write pointer and each read increments the read pointer. During the overflow * condition, writing (tracing) is disabled. Tracing will continue as soon as the overflow condition is * resolved. The first entry that is written immediately following the overflow condition may be marked to * indicate that a tracing discontinuity has occurred before this entry. During the underflow condition, * reading does not increment the read pointer and the read data is marked to indicate that no read data is * available. * * The full threshold events are defined to signal an interrupt a certain levels of "fullness" (1/2, 3/4, 4/4). * "fullness" is defined as the relative distance between the write and read pointers (i.e. not defined as the * absolute distance between the write pointer and entry 0). When enabled, the full threshold event occurs * every time the desired level of "fullness" is achieved. * * * Trace buffer entry format * @verbatim * 6 5 4 3 2 1 0 * 3 2 1 0 9 8 7 6 5 4 3 2 1 0 9 8 7 6 5 4 3 2 1 0 9 8 7 6 5 4 3 2 1 0 9 8 7 6 5 4 3 2 1 0 9 8 7 6 5 4 3 2 1 0 9 8 7 6 5 4 3 2 1 0 * +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ * |sta| address[35:3] | 0 | src id | 0 | DWB | diff timestamp| * +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ * |sta| address[35:3] | 0 | src id | 0 | PL2 | diff timestamp| * +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ * |sta| address[35:3] | 0 | src id | 0 | PSL1 | diff timestamp| * +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ * |sta| address[35:3] | 0 | src id | 0 | LDD | diff timestamp| * +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ * |sta| address[35:3] | 0 | src id | 0 | LDI | diff timestamp| * +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ * |sta| address[35:3] | 0 | src id | 0 | LDT | diff timestamp| * +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ * |sta| address[35:3] | * or 16B mask | src id | 0 | STC | diff timestamp| * +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ * |sta| address[35:3] | * or 16B mask | src id | 0 | STF | diff timestamp| * +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ * |sta| address[35:3] | * or 16B mask | src id | 0 | STP | diff timestamp| * +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ * |sta| address[35:3] | * or 16B mask | src id | 0 | STT | diff timestamp| * +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ * |sta| address[35:0] | 0 | src id| dest id |IOBLD8 | diff timestamp| * +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ * |sta| address[35:1] | 0 | src id| dest id |IOBLD16| diff timestamp| * +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ * |sta| address[35:2] | 0 | src id| dest id |IOBLD32| diff timestamp| * +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ * |sta| address[35:3] | 0 | src id| dest id |IOBLD64| diff timestamp| * +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ * |sta| address[35:3] | * or 16B mask | src id| dest id |IOBST | diff timestamp| * +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ * |sta| * or address[35:3] | * or length | src id| dest id |IOBDMA | diff timestamp| * +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ * * * Trace buffer entry format in Octeon2 is different * * 6 5 4 3 2 1 0 * 8 7 6 5 4 3 2 1 0 9 8 7 6 5 4 3 2 1 0 9 8 7 6 5 4 3 2 1 0 9 8 7 6 5 4 3 2 1 0 9 8 7 6 5 4 3 2 1 0 9 8 7 6 5 4 3 2 1 0 9 8 7 6 5 4 3 2 1 0 * +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ * |sta| address[37:0] | 0 | src id | Group 1 | diff timestamp| * +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ * |sta| address[37:0] | 0 | xmd mask | src id | Group 2 | diff timestamp| * +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ * |sta| address[37:0] | 0 |s-did| dest id | src id | Group 3 | diff timestamp| * +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ * |sta| *address[37:3] | *Length | dest id | src id | Group 4 | diff timestamp| * +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ * * notes: * -
