For 40G optics there is SAI handling of T0 facing ports to be set with SR4 type and unreliable los set for a fixed set of ports. For this property to be invoked the requirement is set
phy_unlos_msft=1 in config.bcm.
This change is to meet the requirement and once this property is set, the los/interface type settings is applied by SAI on the required ports.
Why I did it
For Arista-7060CX-32S-Q32 T1, 40G ports RX_ERR minimalization during connected device reboot
can be achieved by turning on Unreliable LOS and SR4 media_type for all ports which are connected to T0.
The property phy_unlos_msft=1 is to exclusively enable this property.
Microsoft ADO: 25941176
How I did it
Changes in SAI and turning on property
How to verify it
Ran the changes on a testbed and verified configurations are as intended.
with property
admin@sonic2:~$ bcmcmd "phy diag xe8 dsc config" | grep -C 2 "LOS"
Brdfe_on = 0
Media Type = 2
Unreliable LOS = 1
Scrambling Disable = 0
Lane Config from PCS = 0
without property
admin@sonic:~$ bcmcmd "phy diag xe8 dsc config" | grep -C 2 "LOS"
Brdfe_on = 0
Media Type = 0
Unreliable LOS = 0
Scrambling Disable = 0
Lane Config from PCS = 0

Why I did it
sonic-mgmt is failing tests due to invalid test data in platform.json
Fwutil is upset the chassis name in the platform_component.json of the 7060CX-32S
How I did it
Fixed the aforementioned issues
Why I did it
The sensors and sensord processes were reporting data on unused sensors.
This lead to ALARM messages or erroneous values that could be misinterpreted.
How I did it
Ignore the affected sensors in the sensors.conf
How to verify it
Check that there are no longer ALARM messages from sensord in the syslog or in the output of sensors
Why I did it
Some sonic-mgmt platform_tests/api were failing on the 7060CX-32S
How I did it
Added the missing metadata in platform.json and platform_components.json
This is purely test data and does not impact our API implementation.
How to verify it
Run platform_tests / api and expect 100% pass rate.

Why I did it
Arista 7060 platform has a rare and unreproduceable PCIe timeout that could possibly be solved with increasing the switch PCIe timeout value. To do this we'll call a script for this platform to increase the PCIe timeout on boot-up.
No issues would be expected from the setpci command. From the PCIe spec:
"Software is permitted to change the value in this field at any
time. For Requests already pending when the Completion
Timeout Value is changed, hardware is permitted to use either
the new or the old value for the outstanding Requests, and is
permitted to base the start time for each Request either on when
this value was changed or on when each request was issued. "
How I did it
Add "platform-init" support in swss docker similar to how "hwsku-init" is called, only this would be for any device belonging to a platform. Then the script would reside in device data folder.
Additionally, add pciutils dependency to docker-orchagent so it can run the setpci commands.
How to verify it
On bootup of an Arista 7060, can execute:
lspci -vv -s 01:00.0 | grep -i "devctl2"
In order to check that the timeout has changed.
#### Why I did it
Add platform_asic file to each platform folder in sonic-device-data package. The file content will be used as the ground truth of mapping from PLATFORM_STRING to switch ASIC family.
One use case of the mapping is to prevent installing a wrong image, which targets for other ASIC platforms. For example, currently we have several ONIE images naming as sonic-*.bin, it's easy to mistakenly install the wrong image. With this mapping built into image, we could fetch the ONIE platform string, and figure out which ASIC it is using, and check we are installing the correct image.
After this PR merged, each platform vendor has to add one mandatory text file `device/PLATFORM_VENDOR/PLATFORM_STRING/platform_asic`, with the content of the platform's switch ASIC family.
I will update https://github.com/Azure/SONiC/wiki/Porting-Guide after this PR is merged.
You can get a list of the ASIC platforms by `ls -b platform | cat`. Currently the options are
```
barefoot
broadcom
cavium
centec
centec-arm64
generic
innovium
marvell
marvell-arm64

#### How I did it
#### How to verify it
Test one image on DUT. And check the folders under `/usr/share/sonic/device`
Depends on Azure/sonic-utilities#1626
Depends on Azure/sonic-swss#1754
QOS tables in config db used ABNF format i.e "[TABLE_NAME|name] to refer fieldvalue to other qos tables.
Example:
Config DB:
"Ethernet92|3": {
"scheduler": "[SCHEDULER|scheduler.1]",
"wred_profile": "[WRED_PROFILE|AZURE_LOSSLESS]"
},
"Ethernet0|0": {
"profile": "[BUFFER_PROFILE|ingress_lossy_profile]"
},
"Ethernet0": {
"dscp_to_tc_map": "[DSCP_TO_TC_MAP|AZURE]",
"pfc_enable": "3,4",
"pfc_to_queue_map": "[MAP_PFC_PRIORITY_TO_QUEUE|AZURE]",
"tc_to_pg_map": "[TC_TO_PRIORITY_GROUP_MAP|AZURE]",
"tc_to_queue_map": "[TC_TO_QUEUE_MAP|AZURE]"
},
This format is not consistent with other DB schema followed in sonic.
And also this reference in DB is not required, This is taken care by YANG "leafref".
Removed this format from all platform files to consistent with other sonic db schema.
Example:
"Ethernet92|3": {
"scheduler": "scheduler.1",
"wred_profile": "AZURE_LOSSLESS"
},

#### Why I did it
- To start support of dynamic port breakout as the norm for Arista platforms.
- Add a DPB hwsku for the 7060CX-32S
#### How I did it

- Added a new hwsku specifically for DPB
- Added a flex Broadcom configuration

- Why I did it
The pcie configuration file location is under plugin directory not under platform directory.
#6437
- How I did it
Move all pcie.yaml configuration file from plugin to platform directory.
Remove unnecessary timer to start pcie-check.service
Move pcie-check.service to sonic-host-services
- How to verify it
Verify on the device
Prevent system-healthd from service from failing at boot time due to missing configuration.
Also adds basic support for healthd.
The following caveat exists with this placeholder configuration:
- No PSU monitoring (sensors/fans)
- No ASIC temperature monitoring
platform.json is needed for sonic-mgmt testing. Also in the future it will be used as part of dynamic port breakout.
Also removed the folder symlink for BlackhawkDD because it has a different platform.json than BlackhawkO.

* Improve flash space usage during installation
Some older systems only have 2GB of flash available. Installing a second
image on these can prove to be challenging.
The new installation process moves the installer swi to memory in order
to avoid free up space from the flash before uncompressing it there.
It removes all the flash space usage spike and also improves the IO
since the installation is no more reading and writting to the flash at
the same time.
