[DTrace-devel] [PATCH 03/19] Widen the EPID to include the PRID
eugene.loh at oracle.com
eugene.loh at oracle.com
Thu Aug 29 05:25:42 UTC 2024
From: Eugene Loh <eugene.loh at oracle.com>
Each output record has an EPID associated with it. When the consumer
reads a record, it uses the EPID to look up both a PRID (so it can
report PRID and probe function and name) and a data description.
During code generation, the PRID and data description are known,
and so the EPID is set during relocation.
However, we want to support underlying probes that trigger for PRIDs
that will be discovered at run time. So, expand the EPID to 64 bits:
*) the lower half, known at code generation, will index into an
array dtp->dt_stmts[] of statements, which have information
about probe descriptions, data descriptions, and clauses to call
*) the upper half will have the PRID, which will be discovered
at run time
Statement descriptions include a new member dtsd_index, which is
the index to dtp->dt_stmts[].
The consumer gets information about the firing probe from the PRID,
an index to dtp->dt_probes[].
The lower half "EPID" depends only on the statement and no longer
on the specific probe that is firing. Its value is known at code
generation for a compiled clause. It no longer needs to be set in
relocation; that relocation will be removed in a future patch.
The buffer memory pointed to by dctx->buf is rearranged so that EPID
will (still) fall on an 8-byte boundary but now take up 8 bytes.
We do not need to expand:
- the mstate (since it already had the PRID)
Rename mstate's epid to be a statement ID, stid. When
the producer needs the epid, it can construct it from
mst->prid and mst->stid.
- the output buffer (since it already had unused padding)
The new, wider EPID is seen for the built-in variable epid as well
as the epid that the consumer reads.
The probe descriptions dt_pdesc become superfluous and will be
eliminated in a future patch.
Update test files:
- Where the upper 32 bits of the EPID are known (since the PRID
corresponds to a dtrace::: probe), update the expected EPID in
the .r files.
- Where the upper 32 bits of the EPID are not known, add .r.p
processing to filter those bits out before comparing to known
results in .r files.
- Increase expected EPID width.
