Add gearbox phy device files and a new physyncd docker to support VS gearbox phy feature (sonic-net#4851)
* buildimage: Add gearbox phy device files and a new physyncd docker to support VS gearbox phy feature * scripts and configuration needed to support a second syncd docker (physyncd) * physyncd supports gearbox device and phy SAI APIs and runs multiple instances of syncd, one per phy in the device * support for VS target (sonic-sairedis vslib has been extended to support a virtual BCM81724 gearbox PHY). HLD is located at https://github.com/Azure/SONiC/blob/b817a12fd89520d3fd26bbc5897487928e7f6de7/doc/gearbox/gearbox_mgr_design.md **- Why I did it** This work is part of the gearbox phy joint effort between Microsoft and Broadcom, and is based on multi-switch support in sonic-sairedis. **- How I did it** Overall feature was implemented across several projects. The collective pull requests (some in late stages of review at this point): sonic-net/sonic-utilities#931 - CLI (merged) sonic-net/sonic-swss-common#347 - Minor changes (merged) sonic-net/sonic-swss#1321 - gearsyncd, config parsers, changes to orchargent to create gearbox phy on supported systems sonic-net/sonic-sairedis#624 - physyncd, virtual BCM81724 gearbox phy added to vslib **- How to verify it** In a vslib build: root@sonic:/home/admin# show gearbox interfaces status PHY Id Interface MAC Lanes MAC Lane Speed PHY Lanes PHY Lane Speed Line Lanes Line Lane Speed Oper Admin -------- ----------- --------------- ---------------- --------------- ---------------- ------------ ----------------- ------ ------- 1 Ethernet48 121,122,123,124 25G 200,201,202,203 25G 204,205 50G down down 1 Ethernet49 125,126,127,128 25G 206,207,208,209 25G 210,211 50G down down 1 Ethernet50 69,70,71,72 25G 212,213,214,215 25G 216 100G down down In addition, docker ps | grep phy should show a physyncd docker running.

# Changing the virtual device
2+
3+
You can control the hw sku and default factory configuration for the VS image
4+
by modifying the content of the file default_sku in this directory.
5+
6+
The format of default_sku is a single line:
7+
8+
```
9+
<hw_key> <default_preset>
10+
```
11+
12+
## Allowable values for hw_key
13+
14+
| hw_key | Device |
15+
| ------ | ------ |
16+
| Force10-S6000 | Dell Force10 S6000|
17+
| brcm_gearbox_vs | Similar to Force10-S6000, but implements a virtual BRCM81724 Gearbox Phy |
18+
19+
## Allowable values for default_preset
20+
21+
These include "t1", "l2", and "empty". See the file
22+
sonic-buildimage/src/sonic-config-engine/config_samples.py for details on how
23+
each default_preset value is interpreted.
24+
25+
# Changing the hwsku of an existing VS switch
26+
27+
To change the default hwsku for a VS image that has already been built and installed, follow these steps:
28+
29+
- Edit /usr/share/sonic/device/x86_64-kvm_x86_64-r0/default_sku. For details, see the section below (Device Specific Documentation)
30+
- Edit /etc/sonic/config_db.json, and change the "hwsku" key in DEVICE_METADATA:localhost to match the hw_key used in default_sku. Example:
31+
32+
"DEVICE_METADATA": {
33+
"localhost": {
34+
...
35+
"hwsku": "brcm_gearbox_vs",
36+
...
37+
}
38+
},
39+
...
40+
- Reboot the switch
41+
- Use "show platform summary" to verify, and follow any steps specific to the platform, as needed, such as those described below for the brcm_gearbox_vs hwsku.
42+
43+
# Device Specific Documentation
44+
45+
For general info on building, see https://github.com/Azure/sonic-buildimage/blob/master/README.md
46+
47+
## Force-10-S6000
48+
49+
This is the default VS for SONiC. To enable, set contents of default_sku to:
50+
51+
```
52+
Force10-S6000 t1
53+
```
54+
55+
To build:
56+
57+
```
58+
make init
59+
make configure PLATFORM=vs
60+
make target/sonic-vs.img.gz
61+
```
62+
63+
## brcm_gearbox_vs
64+
65+
This sku simulates a device with a Broadcom BRCM81724 gearbox PHY. To enable,
66+
set default_sku to:
67+
68+
69+
```
70+
brcm_gearbox_vs t1
71+
```
72+
73+
To build (same as Force-10-S6000):
74+
75+
```
76+
make init
77+
make configure PLATFORM=vs
78+
make target/sonic-vs.img.gz
79+
```
80+
81+
To verify, install and bring up SONiC. There will be a new gbsyncd docker
82+
which is designed to respond to configuration directed towards the gearbox phy
83+
"switch". swss will create that gearbox switch on startup after detecting the
84+
gearbox is present (this is done by a short lived gearsyncd that runs in the
85+
swss docker).
86+
87+
The commands "show gearbox interfaces status" and "show gearbox phys status" can be
88+
used to verify the virtual gearbox phy has been created. See https://github.com/Azure/sonic-utilities/blob/master/doc/Command-Reference.md#gearbox for details.
