Hi All,

Here is v5 of my patch-set, to delay fbcon taking over the console
(and
binding to fbdev devices) until there actually is some text output
to the
console. This is intended for use with the "quiet" cmdline option,
in
combination with a bootloader which leaves the vendor's logo /
EFI bootgraphics put up by the firmware intact on the EFI
framebuffer.

The end goal here is a boot where the firmware shows its boot
graphics
and these stay in place for a couple of seconds until the GUI loads
and
the GUI then smoothly takes over the framebuffer without any
distruptions.

Bartlomiej, I believe that this patch-set is ready for merging now
and
the first patch has Petr's ack, so can we get this merged now?

Done, thanks for patches (also for reviews & acks).

Also please create an inmutable (or topic) branch for this, so that
the
drm people can merge it into drm-tip for additional testing.

Daniel,
