These are going to be supported by kgi_display specific (permanent,
in the contrast to mode-dependent) kgi_resources. These are not yet
defined in kgi.h.
Basically we'll have to define a new resource, e.g.
typdef enum kgi_resource_type
{
...
KGI_RT_INTERFACE = 0x20000000,
KGI_RT_DDC,
KGI_RT_VMI,
...
};
and a corresponding resource struct
typedef struct
{
... interface information
... management functions
... setup functions
} kgi_vmi_interface;
However, it's hard to get documentation on the parts at the other
side of the bus (e.g. MPEG decodes etc.)...
