disp_module_info_t

Driver module information

Synopsis:

#include <display.h>

typedef struct disp_module_info {
    uint8_t     ddk_version_major;
    uint8_t     ddk_version_minor;
    uint8_t     ddk_rev;
    uint8_t     driver_rev;
    char        *description;
    unsigned    reserved[16];
} disp_module_info_t;

Description:

The disp_module_info_t structure stores module information about your driver. Your driver must fill in this structure when the graphics framework calls the module_info() function that your driver defines in these structures:

• disp_draw_miscfuncs_t
• disp_memfuncs_t
• disp_modefuncs_t
• disp_vidfuncs_t

The members of the disp_module_info_t structure include:

ddk_version_major

The major version number of the Graphics DDK that you used to build your driver. Set this to DDK_VERSION_MAJOR.

ddk_version_minor

The minor version number of the DDK; set it to DDK_VERSION_MINOR.

ddk_rev

The revision number of the DDK; set it to DDK_REVISION.

driver_rev

The revision of the driver; use this member as you see fit.

description

A string that describes the driver module. The recommended format is the driver name, followed by a space, a hyphen, another space, and then a generic description of the hardware that the driver should support. For example, vga - driver for VGA-compatible devices.
