◆ read_sdb()
| std::optional< struct sdb_device_info > read_sdb | ( | struct pcie_bars * | bars, |
| device_match_fn | device_match, | ||
| unsigned | pos | ||
| ) |
This function navigates the SDB filesystem and passes decoded SDB product entries to device_match. When device_match returns true for the pos -th time, this function returns that SDB device's information; the address can be used to locate the device's register map, and the version information makes it possible to gate functionality behind version checks. If device_match is null, pos is ignored and this function simply prints all SDB information.
