Linux Kernel Driver for Huawei Intelligent NIC(HiNIC3) family
5+
============================================================
6+
7+
Overview:
8+
=========
9+
HiNIC3 is a network interface card for the Data Center Area.
10+
11+
The driver supports a range of link-speed devices (10GbE, 25GbE, 40GbE, etc.).
12+
The driver supports also a negotiated and extendable feature set.
13+
14+
Some HiNIC3 devices support SR-IOV. This driver is used for Physical Function
15+
(PF).
16+
17+
HiNIC3 devices support MSI-X interrupt vector for each Tx/Rx queue and
18+
adaptive interrupt moderation.
19+
20+
HiNIC3 devices support also various offload features such as checksum offload,
21+
TCP Transmit Segmentation Offload(TSO), Receive-Side Scaling(RSS) and
22+
LRO(Large Receive Offload).
23+
24+
25+
Supported PCI vendor ID/device IDs:
26+
===================================
27+
28+
19e5:1822 - HiNIC3 PF
29+
30+
31+
Driver Architecture and Source Code:
32+
====================================
33+
34+
hinic3_dev - Implement a Logical Network device that is independent from
35+
specific HW details about HW data structure formats.
36+
37+
hinic3_hwdev - Implement the HW details of the device and include the components
38+
for accessing the PCI NIC.
39+
40+
hinic3_hwdev contains the following components:
41+
===============================================
42+
43+
HW Interface:
44+
=============
45+
46+
The interface for accessing the pci device (DMA memory and PCI BARs).
47+
(hinic3_hw_if.c, hinic3_hw_if.h)
48+
49+
Configuration Status Registers Area that describes the HW Registers on the
50+
configuration and status BAR0. (hinic3_hw_csr.h)
51+
52+
MGMT components:
53+
================
54+
55+
Asynchronous Event Queues(AEQs) - The event queues for receiving messages from
56+
the MGMT modules on the cards. (hinic3_hw_eqs.c, hinic3_hw_eqs.h)
57+
58+
Application Programmable Interface commands(API CMD) - Interface for sending
59+
MGMT commands to the card. (hinic3_hw_api_cmd.c, hinic3_hw_api_cmd.h)
60+
61+
Management (MGMT) - the PF to MGMT channel that uses API CMD for sending MGMT
62+
commands to the card and receives notifications from the MGMT modules on the
63+
card by AEQs. Also set the addresses of the IO CMDQs in HW.
64+
(hinic3_hw_mgmt.c, hinic3_hw_mgmt.h)
65+
66+
IO components:
67+
==============
68+
69+
Completion Event Queues(CEQs) - The completion Event Queues that describe IO
70+
tasks that are finished. (hinic3_hw_eqs.c, hinic3_hw_eqs.h)
71+
72+
Work Queues(WQ) - Contain the memory and operations for use by CMD queues and
73+
the Queue Pairs. The WQ is a Memory Block in a Page. The Block contains
74+
pointers to Memory Areas that are the Memory for the Work Queue Elements(WQEs).
75+
(hinic3_hw_wq.c, hinic3_hw_wq.h)
76+
77+
Command Queues(CMDQ) - The queues for sending commands for IO management and is
78+
used to set the QPs addresses in HW. The commands completion events are
79+
accumulated on the CEQ that is configured to receive the CMDQ completion events.
80+
(hinic3_hw_cmdq.c, hinic3_hw_cmdq.h)
81+
82+
Queue Pairs(QPs) - The HW Receive and Send queues for Receiving and Transmitting
83+
Data. (hinic3_hw_qp.c, hinic3_hw_qp.h, hinic3_hw_qp_ctxt.h)
84+
85+
IO - de/constructs all the IO components. (hinic3_hw_io.c, hinic3_hw_io.h)
86+
87+
CQM components:
88+
==========
89+
90+
The CQM module organizes the memory in the large system in a format (CLA table)
91+
and allocates the memory to the chip (BAT table). The chip can use the memory in
92+
the large system to save context information and queue information (SCQ\SRQ).
93+
(cqm_bat_cla.c, cqm_bat_cla.h, cqm_bitmap_table.c, cqm_bitmap_table.h)
94+
95+
When a packet is transmitted from the PCIe link, the chip parses the 5-tuple
96+
such as sid, did, and hostid. Fill the parsed data in the queue
97+
(in the form of scqe). In this way, the driver can directly obtain data from the
98+
queue (through MPDK polling) and then process the data. In this way, the
99+
uninstallation is implemented.
100+
(cqm_main.c, cqm_main.h, cqm_db.c, cqm_db.h)
101+
102+
HW device:
103+
==========
104+
105+
HW device - de/constructs the HW Interface, the MGMT components on the
106+
initialization of the driver and the IO components on the case of Interface
107+
UP/DOWN Events. (hinic3_hw_dev.c, hinic3_hw_dev.h)
108+
109+
110+
hinic3_dev contains the following components:
111+
===============================================
112+
113+
PCI ID table - Contains the supported PCI Vendor/Device IDs.
114+
(hinic3_pci_tbl.h)
115+
116+
Port Commands - Send commands to the HW device for port management
117+
(MAC, Vlan, MTU, ...). (hinic3_port.c, hinic3_port.h)
118+
119+
Tx Queues - Logical Tx Queues that use the HW Send Queues for transmit.
120+
The Logical Tx queue is not dependent on the format of the HW Send Queue.
121+
(hinic3_tx.c, hinic3_tx.h)
122+
123+
Rx Queues - Logical Rx Queues that use the HW Receive Queues for receive.
124+
The Logical Rx queue is not dependent on the format of the HW Receive Queue.
125+
(hinic3_rx.c, hinic3_rx.h)
126+
127+
hinic_dev - de/constructs the Logical Tx and Rx Queues.
128+
(hinic3_main.c, hinic3_dev.h)
129+
130+
131+
Miscellaneous:
132+
=============
133+
134+
Common functions that are used by HW and Logical Device.
135+
(hinic3_common.c, hinic3_common.h)
136+
137+
138+
Support
139+
=======
140+
141+
If an issue is identified with the released source code on the supported kernel
142+
with a supported adapter, email the specific information related to the issue to
143+
wulike1@huawei.com.
