yocto - which recipe will be used first?

Question

If I have many recipes, ex:

dmidecode_1.0.bb
dmidecode_1.1.bb
dmidecode_git.bb

when I doing:

CORE_IMAGE_EXTRA_INSTALL += "dmidecode"

which recipe will be used?

Answer 1

bitbake -e dmidecode | grep -e "^PV=" will tell you.

The layer priority (BBFILE_PRIORITY) takes precedence, then PV which is dynamically set if you're getting the sources from git IIRC. There's also DEFAULT_PREFERENCE that can be set and modifies the logic behind version precedence.
