typedef struct {
int version;
int size;
int chipset;
int physmem;
int physmemsize;

} vga_cardinfo;
The fields meaning in detail:
Basic mode details
- version
- Version of the information structure. Application can use this field to make sure the data it needs is really there.
- size
- Size of the cardinfo structure. The structure is malloc()ed, and the program should free it when no longer needed.
- chipset
- Number of the chispet driver used to drive the card. Same list as is used in the vga_setchipset function.
- physmem
- Physical address of the linear memory aperture of the card. This is needed for example for setting the video overlay of v4l devices.
- physmemsize
- Amount of physical memory in bytes. (Version >= 0x0200)
- linearmem
- Virtual address of the linear memory aperture. Please note that currently it is mapped at vga_init, but in future versions of svgalib this might change. (Version >= 0x0200)
