Hi,
I see that a lot of PCI device drivers use code to check their ID's.
One simple way to dump all the PCI device ID's is to compile or load all
modules and then make a dummy PCI device, which only calls device_probe on the
full 32-bit space of the pci_get_devid(). This should take in matter of some
minutes to produce a complete list of PCI ID's. Then add these ID's to all the
respective drivers like a generic device ID table:
struct pci_device_id {
uint32_t device_id;
uint32_t card_id;
const char *description;
unsigned long driver_info;
} __aligned(32);
Then export those automatically generated structures into the "pci_device_id"
section and have tools/bus_autoconf generate the matching rules.
PCI format structure for bus_autoconf:
"pci_device_id{256,:}"
"device_id[0]{" U32_XOR ",8}"
"device_id[1]{" U32_XOR ",8}"
"device_id[2]{" U32_XOR ",8}"
"device_id[3]{" U32_XOR ",8}"
"card_id[0]{" U32_XOR ",8}"
"card_id[1]{" U32_XOR ",8}"
"card_id[2]{" U32_XOR ",8}"
"card_id[3]{" U32_XOR ",8}"
