sounds like we need a union, with a tag, and then the descriptors. In the
limit, the tag can be TAG_CODE, meaning you have to call the attached data
blob:
enum {TAG_CODE, TAG_PCI_CONFIG, TAG_ISA, TAG_CPU} ;
typedef struct {
unsigned short vendor, device;
u8 function, register;
u8 and, or;
} pci_config_data;
typedef struct {
u16 iobase;
u8 and, or;
} isa;
typedef struct {
unsigned long msr;
unsigned long long and, or;
} cpu;
// has to be PIC.
typedef struct {
unsigned long len;
char code;
} code;
typedef struct {
u8 tag;
union {
pci_config_data pci;
isa isa;
cpu cpu;
code code;
} data;
};
Would this do it?
