|
|
Generally, video drivers request the amount of memory they need for
|
|
the frame buffer when they are bound, by setting the size field in
|
|
struct video_uc_plat. That memory is then reserved for use after
|
|
relocation. But PCI drivers cannot be bound before relocation unless
|
|
they are mentioned in the devicetree.
|
|
|
|
With this value set appropriately, it is possible for PCI video
|
|
devices to have a framebuffer allocated by U-Boot.
|
|
|
|
Note: the framebuffer needs to be large enough to store all pixels at
|
|
maximum resolution. For example, at 2560 x 1600 with 32 bits per
|
|
pixel, 2560 * 1600 * 32 / 8 = 0xfa0000 bytes are needed.

help
|

On some machines (e.g. x86), reading from the frame buffer is very

|
slow because it is uncached. To improve performance, this feature
|
|
allows the frame buffer to be kept in cached memory (allocated by
|
|
U-Boot) and then copied to the hardware frame-buffer as needed.
|
|
|
|
To use this, your video driver must set @copy_base in

struct video_uc_plat.

pixels and is the nominal height of a character. Note that fonts

are commonly measured in 'points', being 1/72 inch (about 3.52mm).

However that measurement depends on the size of your display and

U-Boot to calculate the correct font size.

This sets the number of font / size combinations which can be used by

boot menus are in use, this may need to be increased.
|

Note that a separate entry is needed for each font size, even if the

font itself is the same. This is because the entry caches various

font metrics which are expensive to regenerate each time the font

size changes.

splash image from supported locations, and a way of controlling the

selected splash location using the "splashsource" environment
|

This CONFIG works as follows:
|

- If splashsource is set to a supported location name as defined by

board code, use that splash location.

default.
|

- If splashsource is set to an unsupported value, do not load a splash
|
|
screen.
|
|
|
|
A splash source location can describe either storage with raw data, a
|
|
storage formatted with a file system or a FIT image. In case of a

|
filesystem, the splash screen data is loaded as a file. The name of
|
|
the splash screen file can be controlled with the environment variable
|
|
"splashfile".
|
|

To enable loading the splash image from a FIT image, CONFIG_FIT must

be enabled. The FIT image has to start at the 'offset' field address
|
|
in the selected splash location. The name of splash image within the
|
|
FIT shall be specified by the environment variable "splashfile".
|

In case the environment variable "splashfile" is not defined the

If this is acceptable and you have a need to use video drivers in

|
Generally, video drivers request the amount of memory they need for
|
|
the frame buffer when they are bound, by setting the size field in
|
|
struct video_uc_plat. That memory is then reserved for use after
|
|
relocation. But PCI drivers cannot be bound before relocation unless
|
|
they are mentioned in the devicetree.
|
|
|
|
With this value set appropriately, it is possible for PCI video
|
|
devices to have a framebuffer allocated by U-Boot.
|
|
|
|
Note: the framebuffer needs to be large enough to store all pixels at
|
|
maximum resolution. For example, at 2560 x 1600 with 32 bits per
|
|
pixel, 2560 * 1600 * 32 / 8 = 0xfa0000 bytes are needed.

config SPL_SPLASH_SOURCE

help

Use the splash_source.c library. This library provides facilities to

|
declare board specific splash image locations, routines for loading
|
|
splash image from supported locations, and a way of controlling the
|
|
selected splash location using the "splashsource" environment
|
|
variable.
|
|
|
|
This CONFIG works as follows:
|
|
|
|
- If splashsource is set to a supported location name as defined by
|
|
board code, use that splash location.
|
|
- If splashsource is undefined, use the first splash location as
|
|
default.
|
|
- If splashsource is set to an unsupported value, do not load a splash
|
|
screen.
|
|
|
|
A splash source location can describe either storage with raw data, a
|
|
storage formatted with a file system or a FIT image. In case of a
|
|
filesystem, the splash screen data is loaded as a file. The name of
|
|
the splash screen file can be controlled with the environment variable
|
|
"splashfile".
|
|
|
|
To enable loading the splash image from a FIT image, CONFIG_FIT must
|
|
be enabled. The FIT image has to start at the 'offset' field address
|
|
in the selected splash location. The name of splash image within the
|
|
FIT shall be specified by the environment variable "splashfile".
|
|
|
|
In case the environment variable "splashfile" is not defined the
|
|
default name 'splash.bmp' will be used.
