PATCH v4 3/19 Deprecate enabled probe ID (epid)

From: Eugene Loh <[email protected]>

Historically, the enabled probe id (epid) was an integer, passed from producer to consumer, that uniquely identified probe ID and statement (data description). It was used in error reporting and was available to D users via a built-in variable "epid".

However, its value was opaque to users and difficult to use.

Deprecate the use of EPID:

*) Have the producer pass to the consumer the probe ID and statement
ID explicitly, instead of passing an opaque integer that requires additional lookup tables.

*) Keep an array dt_stmts[] of statements, from which we can retrieve
probe descriptions and data descriptions.

*) Remove data structures related to epid: dt_ddesc[], dt_pdesc[],
dt_nextepid, dt_maxprobe, etc.

Nevertheless, continue to provide a value for the built-in "epid" variable for back compatability. Expand the epid from 4 bytes to 8 bytes: the upper half is the probe ID and the lower half the statement ID.

The output buffer (written by the producer, read by the consumer) is rearranged slightly. Note that:

*) It starts with a 4-byte size, which perf_event writes.

*) The beginning of the output buffer should have 8-byte alignment.

*) The beginning of the trace data within the output buffer should
also have 8-byte alignment.

*) So we rearrange as follows:

old new

0: pad / size pad / size <==
4: pad specid
8: epid <== prid
12: specid stid
16: data[n] data[n]

The arrow <== indicates where the buffer starts.

For error reporting:

*) Report errors in terms of the probe ID (and description) and the
clause function name, which is decipherable in terms of the disassembly output. Specifically, change ERROR-probe arguments:

-) arg1 changes from epid to the probe ID

-) arg2 changes from "clause index" (which is no longer needed)
to the statement ID that identifies the clause named in disassembly output

*) No longer report the "action number", which has lost much of its
meaning in the port to eBPF. Nonetheless, keep dteda_action; its value is not used, but set the value to stid for possible future use.
