Why This File Exists

Repeatable hardware-adapter layer. Deep compatibility for every driver is out of scope; this atlas records patterns, probe lifecycles, bus glue, IRQ/DMA usage, and links back to core abstractions.

/* The code can defined cpp macros for creating a PCI Device ID Table. This is
 * useful because it allows the PCI ID Table to be maintained in a single place.
 *
 * The macros are:
 *
 * CH_PCI_DEVICE_ID_TABLE_DEFINE_BEGIN
 *   -- Used to start the definition of the PCI ID Table.
 *
 * CH_PCI_DEVICE_ID_FUNCTION
 *   -- The PCI Function Number to use in the PCI Device ID Table.  "0"
 *   -- for drivers attaching to PF0-3, "4" for drivers attaching to PF4,
 *   -- "8" for drivers attaching to SR-IOV Virtual Functions, etc.
 *
 * CH_PCI_DEVICE_ID_FUNCTION2 [optional]
 *   -- If defined, create a PCI Device ID Table with both
 *   -- CH_PCI_DEVICE_ID_FUNCTION and CH_PCI_DEVICE_ID_FUNCTION2 populated.
 *
 * CH_PCI_ID_TABLE_ENTRY(DeviceID)
 *   -- Used for the individual PCI Device ID entries.  Note that we will
 *   -- be adding a trailing comma (",") after all of the entries (and
 *   -- between the pairs of entries if CH_PCI_DEVICE_ID_FUNCTION2 is defined).
 *
 * CH_PCI_DEVICE_ID_TABLE_DEFINE_END
 *   -- Used to finish the definition of the PCI ID Table.  Note that we
 *   -- will be adding a trailing semi-colon (";") here.
