* Interface to the Trace buffer hardware.
*
* WRITING THE TRACE BUFFER
*
* When the trace is enabled, commands are traced continuously (wrapping) or until the buffer is filled once
* (no wrapping). 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.

* notes:
* - diff timestamp is the difference in time from the previous trace event to this event - 1. the granularity of the timestamp is programmable
* - Fields marked as '*' are first filled with '0' at XMC time and may be filled with real data later at XMD time. Note that the
* XMD write may be dropped if the shallow FIFO overflows which leaves the '*' fields as '0'.
* - 2 bits (sta) are used not to trace, but to return global state information with each read, encoded as follows:
* 0x0-0x1=not valid
* 0x2=valid, no discontinuity
* 0x3=valid, discontinuity
* - commands are encoded as follows:
* 0x0=DWB
* 0x1=PL2
* 0x2=PSL1
* 0x3=LDD
* 0x4=LDI
* 0x5=LDT
* 0x6=STF
* 0x7=STC
* 0x8=STP
* 0x9=STT
* 0xa=IOBLD8
* 0xb=IOBLD16
* 0xc=IOBLD32
* 0xd=IOBLD64
* 0xe=IOBST
* 0xf=IOBDMA
* - In Octeon2 the commands are grouped as follows:
* Group1:

* XMC_SET8, XMC_SET16, XMC_SET32, XMC_SET64,

* XMC_LDD, XMC_PSL1
* XMC_SAA32, XMC_SAA64,
* XMC_FAA32, XMC_FAA64,
* XMC_FAS32, XMC_FAS64
* Group3:

* XMC_IOBST8, XMC_IOBST16, XMC_IOBST32, XMC_IOBST64
* Group4:
* XMC_IOBDMA
* - For non IOB* commands
* - source id is encoded as follows:
* 0x00-0x0f=PP[n]
* 0x10=IOB(Packet)
* 0x11=IOB(PKO)
* 0x12=IOB(ReqLoad, ReqStore)
* 0x13=IOB(DWB)
* 0x14-0x1e=illegal
* 0x1f=IOB(generic)
* - dest id is unused (can only be L2c)
* - For IOB* commands
* - source id is encoded as follows:
* 0x00-0x0f = PP[n]
* - dest id is encoded as follows:
* 0 = CIU/GPIO (for CSRs)
* 1-2 = illegal
* 3 = PCIe (access to RSL-type CSRs)
* 4 = KEY (read/write operations)
* 5 = FPA (free pool allocate/free operations)
* 6 = DFA
* 7 = ZIP (doorbell operations)
* 8 = RNG (load/IOBDMA operations)
* 10 = PKO (doorbell operations)
* 11 = illegal
* 12 = POW (get work, add work, status/memory/index loads, NULLrd load operations, CSR operations)
* 13-31 = illegal
