+ * PF<->VF Gen2 Messaging format
+ *
+ * The PF has an array of 32-bit PF2VF registers, one for each VF. The
+ * PF can access all these registers while each VF can access only the one
+ * register associated with that particular VF.
+ *
+ * The register functionally is split into two parts:
+ * The bottom half is for PF->VF messages. In particular when the first
+ * bit of this register (bit 0) gets set an interrupt will be triggered
+ * in the respective VF.
+ * The top half is for VF->PF messages. In particular when the first bit
+ * of this half of register (bit 16) gets set an interrupt will be triggered
+ * in the PF.
+ *
+ * The remaining bits within this register are available to encode messages.
+ * and implement a collision control mechanism to prevent concurrent use of
+ * the PF2VF register by both the PF and VF.

+ * Message Origin (Should always be 1)
+ * A legacy out-of-tree QAT driver allowed for a set of messages not supported
+ * by this driver; these had a Msg Origin of 0 and are ignored by this driver.
+ *
+ * When a PF or VF attempts to send a message in the lower or upper 16 bits,
+ * respectively, the other 16 bits are written to first with a defined
+ * IN_USE_BY pattern as part of a collision control scheme (see function
+ * adf_gen2_pfvf_send() in adf_pf2vf_msg.c).
+ *
+ *
+ * PF<->VF Gen4 Messaging format
+ *
+ * Similarly to the gen2 messaging format, 32-bit long registers are used for
+ * communication between PF and VFs. However, each VF and PF share a pair of
+ * 32-bits register to avoid collisions: one for PV to VF messages and one
+ * for VF to PF messages.
+ *
+ * Both the Interrupt bit and the Message Origin bit retain the same position
+ * and meaning, although non-system messages are now deprecated and not
+ * expected.
