IO - de/constructs all the IO components. (hinic3_hw_io.c, hinic3_hw_io.h)



CQM components:

==========



The CQM module organizes the memory in the large system in a format (CLA table)

and allocates the memory to the chip (BAT table). The chip can use the memory in

the large system to save context information and queue information (SCQ\SRQ).

(cqm_bat_cla.c, cqm_bat_cla.h, cqm_bitmap_table.c, cqm_bitmap_table.h)



When a packet is transmitted from the PCIe link, the chip parses the 5-tuple

such as sid, did, and hostid. Fill the parsed data in the queue

(in the form of scqe). In this way, the driver can directly obtain data from the

queue (through MPDK polling) and then process the data. In this way, the

uninstallation is implemented.

(cqm_main.c, cqm_main.h, cqm_db.c, cqm_db.h)
