From: Simon Glass <simon.glass@canonical.com> When running sandbox with lots of console output, the vidconsole slows things down significantly since it renders truetype fonts to the internal framebuffer. Add a -Q/--quiet_vidconsole command-line option that removes vidconsole from stdout and stderr, using only the serial console. This can provide a ~300x speedup for output-heavy operations.
