Scott,
Off the top of my head, I know SRCPV is a combination of the VCS type and
revision used in the actual build. Most interestingly, SRCPV will always
contain the real revision used in the build, even if ${AUTOREV} is
specified as the SRCREV for a given package. Note that if a package does
not include SRCPV somewhere within its recipe, I believe setting SRCREV to
${AUTOREV} will have no effect, as ${AUTOREV} by itself simply resolves to
the string "AUTOINC", which does not permute the hash of the recipe.
Note that I'm not really a Yocto expert nor am I sitting with the code in
front of me right now, so someone can jump in if I missed something or got
a detail incorrect. I don't remember the exact format of the string, but I
want to say its a combination of the VCS name, a Yocto-internal VCS
identification number (just like 1 or 2, not some huge int), and the
revision (be it a hash it git or an integer in SVN or whatever else is used
by a supported VCS).
Kind regards,
Jerrod
