video/console: Implement reverse video ANSI sequence for DM_VIDEO

2019-04-14T12:18:47+00:00

The video console for DM_VIDEO compliant drivers only understands a very
small number of ANSI sequences. First and foremost it misses the "reverse
video" command, which is used by our own bootmenu command to highlight
the selected entry.

To avoid forcing people to use their imagination when using the
bootmenu, let's just implement the rather simple reverse effect. We need
to store the background colour index for that, so that we can
recalculate both the foreground and background colour pixel values.

video: Allow driver to specify the line length

2018-12-03T18:09:44+00:00

At present line_length is always calculated in video_post_probe(). But
some hardware may use a different line length, e.g. with a 1366-wide
display.

Allow the driver to set this value if needed.

video: Update video_set_default_colors() to support invert

2018-11-21T02:14:22+00:00

It is useful to be able to invert the colours in some cases so that the
text matches the background colour. Add a parameter to the function to
support this.

It is strange that function takes a private data structure from another
driver as an argument. It seems better to pass the device and have the
function internally work out how to find its required information.

All driver-model operation should return an error code. Adjust this

sandbox: video: Speed up video output

2018-10-09T10:40:27+00:00

At present there are many situations where sandbox syncs the display to
the SDL frame buffer. This is a very expensive operation but is only
needed every now and then. Update video_sync() so that we can specify
whether this operation is really needed.

At present this flag is not used on other architectures. It could also
be used for reducing writeback-cache flushes but the benefit of that would
need to be investigated.
