bitbake-getvar does not have a way to silence bitbake server's logger and that makes the tool hard to use for text processing. This is especially true when one wants to get a bitbake value to be piped to some other utility and instead we get uncontrolled logging messages or warnings together with bitbake's variable value. Example without quiet: bitbake-getvar --value MACHINE NOTE: Starting bitbake server... qemux86-64 With quiet: bitbake-getvar --value MACHINE --quiet qemux86-64 (Bitbake rev: af354e975d0b4c26d0e91e3c82946b093bc11b45) Signed-off-by: Paulo Neves <ptsneves@gmail.com> Signed-off-by: Alexandre Belloni <alexandre.belloni@bootlin.com> Signed-off-by: Richard Purdie <richard.purdie@linuxfoundation.org>
