video: add guards around 16bpp/32bbp code

2019-12-06T15:37:45Z

Many boards use only single depth configuration, for such boards there is some unused code in video and console uclass routines. Add guards to avoid dead code. Signed-off-by: Anatolij Gustschin Tested-by: Eugen Hristev Tested-by: Patrice Chotard Tested-by: Steffen Dirkwinkel

video: Factor out vidconsole_put_string()

2019-05-20T10:00:05Z

Pull the vidconsole_put_string() function from DM tests, make it available to e.g. boards that want to display information on the LCD on boot. Signed-off-by: Marek Vasut Cc: Anatolij Gustschin Reviewed-by: Anatolij Gustschin

video/console: Factor out actual character output

2019-04-14T12:18:47Z

In preparation for doing character set translations, factor out the actual glyph display functionality into a separate function. This will be used in a subsequent patch. Signed-off-by: Andre Przywara Reviewed-by: Simon Glass

video/console: Implement ANSI clear line command

2019-04-14T12:18:47Z

There is a standard ANSI terminal escape sequence to clear a whole line of text. So far the DM_VIDEO console was missing this code. Detect the sequence and use vidconsole_set_row with the background colour to fix this omission. Signed-off-by: Andre Przywara Reviewed-by: Simon Glass

video/console: Implement relative cursor movement ANSI handling

2019-04-14T12:18:47Z

The ANSI terminal escapce sequence standard defines relative cursor movement commands (ESC [ A-F). So far the DM_VIDEO console code was ignoring them. Interpret those sequences and move the cursor by the requested amount of rows or columns in the right direction. This brings the code on par with the legacy video console driver (cfb_console).

video/console: Implement reverse video ANSI sequence for DM_VIDEO

2019-04-14T12:18:47Z

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: Update video_set_default_colors() to support invert

2018-11-21T02:14:22Z

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. Signed-off-by: Simon Glass

dm: video: correctly set the cursor position

2018-11-17T10:35:39Z

The terminal escape sequence ESC [ ; H is used to set the cursor position. According to the ECMA 48 standard the upper left corner in the escape sequences is [1, 1]. The video uclass uses [0, 0] as upper left corner. Signed-off-by: Heinrich Schuchardt Reviewed-by: Simon Glass

video: at91: Adjust vidconsole_position_cursor() to use char pos

2018-10-09T10:40:27Z

At present this function uses pixels but it seems more useful for it to position in terms of characters on the screen. This also matches the comment to the function. Update this. Unfortunately there is one user of this function (at91). Have a crack at fixing this, since I cannot test it. Signed-off-by: Simon Glass Reviewed-by: Anatolij Gustschin
