Use the devtool upgrade
command
to upgrade an existing recipe to a new upstream version.
The command puts the upgraded recipe file into the
workspace along with any associated files, and extracts
the source tree to a specified location should patches
need rebased or added to as a result of the upgrade.
When you use the devtool upgrade
command,
you must supply the root name of the recipe (i.e. no version,
paths, or extensions), and you must supply the directory
to which you want the source extracted.
Additional command options let you control things such as
the version number to which you want to upgrade (i.e. the
PV
),
the source revision to which you want to upgrade (i.e. the
SRCREV
,
whether or not to apply patches, and so forth.
