- Why I did it
1. SN2201 sai profile needs to be updated according to the latest hardware.
2. In the reboot script, need to use the common symbol link of the power_cycle sysfs instead of directly accessing it due to SN2201 sysfs is different than other platforms.
3. echo 1 > $SYSFS_PWR_CYCLE will trigger the reboot immediately, the following sleep 3 and echo 0 > $SYSFS_PWR_CYCLE will never be executed, can be removed.
- How I did it
1. Replace the SN2201 sai profile with the latest one.
2. In the platform_reboot script, replace the direct sysfs path with the symbol link path.
3. Remove the redundant code from platform_reboot
- How to verify it
Perform reboot on all the Nvidia platforms, and check all can be rebooted successfully.

Why I did it
As part of PCBB changes, we need to enable 2 extra lossless queues. The changes in this PR are done to adjust only the reserved sizes on Th2 for the additional 2 lossless queues
Calculations are done based on 40 downlinks for T1 and 16 uplinks for dual ToR
How to verify it
Verified that the rendering works fine on Th2 dut
Unit tests have been updated to reflect the modified buffer sizes when pcbb is enabled. There are existing testcases that will test the original buffer sizes when pcbb is disabled. With these changes, was able to build sonic-config-engine wheel successfully

How I did it
Update the buffers.json.j2 template and buffers_config.j2 template to generate new BUFFER_QUEUE table.
For T1 devices, queue 2 and queue 6 are set as lossless queues on T0 facing ports.
For T0 devices, queue 2 and queue 6 are set as lossless queues on T1 facing ports.
Queue 7 is added as a new lossy queue as DSCP 48 is mapped to TC 7, and then mapped into Queue 7
How to verify it
Verified by UT
Verified by coping the new template and generate buffer config with sonic-cfggen
* Removed unused default_config.json
* Remove asic.conf file from HW SKUs directories as they are not used by upstream code

What/Why I did:
Issue1: By setting up of ipvlan interface in interface-config.sh we are not tolerant to failures. Reason being interface-config.service is one-shot and do not have restart capability.
Scenario: For example if let's say database service goes in fail state then interface-services also gets failed because of dependency check but later database service gets restart but interface service will remain in stuck state and the ipvlan interface nevers get created.
Solution: Moved all the logic in database service from interface-config service which looks more align logically also since the namespace is created here and all the network setting (sysctl) are happening here.With this if database starts we recreate the interface.
Issue 2: Use of IPVLAN vs MACVLAN
Currently we are using ipvlan mode. However above failure scenario is not handle correctly by ipvlan mode. Once the ipvlan interface is created and ip address assign to it and if we restart interface-config or database (new PR) service Linux Kernel gives error "Error: Address already assigned to an ipvlan device." based on this:https://github.com/torvalds/linux/blob/master/drivers/net/ipvlan/ipvlan_main.c#L978Reason being if we do not do cleanup of ip address assignment (need to be unique for IPVLAN) it remains in Kernel Database and never goes to free pool even though namespace is deleted.
Solution: Considering this hard dependency of unique ip macvlan mode is better for us and since everything is managed by Linux Kernel and no dependency for on user configured IP address.
Issue3: Namespace database Service do not check reachability to Supervisor Redis Chassis Server.
Currently there is no explicit check as we never do Redis PING from namespace to Supervisor Redis Chassis Server. With this check it's possible we will start database and all other docker even though there is no connectivity and will hit the error/failure late in cycle
Solution: Added explicit PING from namespace that will check this reachability.
Issue 4:flushdb give exception when trying to accces Chassis Server DB over Unix Sokcet.
Solution: Handle gracefully via try..except and log the message.

- Why I did it
Platform_reboot files for simx doesn't do aything different apart from calling /sbin/reboot. which is anyway done in the /usr/local/bin/reboot script i.e. the parent script which calls the platform specific reboot scripts if present.
Moreover, /sbin/reboot invoked in the platform specific reboot script is a non-blocking call and thus it returns back to the original script (although /sbin/reboot does it job in the background) and we see messages like this.

The current code assumes that the value part does not have whitespace. So everything after the whitespace will be ignored. The syseeprom values returned from platform API do not match the output of "show platform syseeprom" on dx010 and e1031 device.
How I did it
This change improved the regular expression for parsing syseeprom values to accommodate whitespaces in the value.
PR 10021 provides the solution, but committed to the wrong place for dx010 and e1031.
How to verify it
Compile the sonic_platform wheel for dx010, then upload to device and install the wheel, verify the platform eeprom API.

* [y_cable] Support for initialization of new Daemon ycable to support
ycables
This PR also adds the commit in sonic-platform-daemons
94fa239 [y_cable] refactor y_cable to a seperate logic and new daemon from xcvrd (#219)
Why I did it
This PR separates the logic of Y-Cable from xcvrd. Before this change we were utilizing xcvrd daemon to control all aspects of Y-Cable right from initialization to processing requests from other entities like orch,linkmgr.
Now we would have another daemon ycabled which will serve this purpose.
Logically everything still remains the same from the perspective of other daemons.
it also take care aspects like init/delete daemon from Y-Cable perspective.
How I did it
To serve the purpose we build a new wheel sonic_ycabled-1.0-py3-none-any.whl and install it inside pmon.
We also initalize the daemon ycabled which serves our purpose for refactor inside pmon

Requirements from Microsoft for fwutil update all state that all firmwares which support this upgrade flow must support upgrade within a single boot cycle. This conflicted with a number of Mellanox upgrade flows which have been revised to safely meet this requirement.
How I did it
Added --no-power-cycle flags to SSD and ONIE firmware scripts
Modified Platform API to call firmware upgrade flows with this new flag during fwutil update all
Added a script to our reboot plugin to handle installing firmwares in the correct order with prior to reboot
How to verify it
Populate platform_components.json with firmware for CPLD / BIOS / ONIE / SSD
Execute fwutil update all fw --boot cold
CPLD will burn / ONIE and BIOS images will stage / SSD will schedule for reboot
Reboot the switch
SSD will install / CPLD will refresh / switch will power cycle into ONIE
ONIE installer will upgrade ONIE and BIOS / switch will reboot back into SONiC
In SONiC run fwutil show status to check that all firmware upgrades were successful
Tested on a Celestica Seastone2 DX030 switch

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
The capability files were incorrect in comparison to the marketing spec of the SN4410 platform.
- How I did it
Aligned the capability files according to the marketing spec.
- How to verify it
Basic manual sanity checks:
1. Check if critical docker containers were UP
2. Check if interfaces were created and were UP
3. Check if interfaces created in the syncd docker container by executing – sx_api_ports_dump.py script
4. Check the logs from the start of the switch – everything was OK
5. Verified the port breakout

Why I did it
Support zero buffer profiles
Add buffer profiles and pool definition for zero buffer profiles
Support applying zero profiles on INACTIVE PORTS
Enable dynamic buffer manager to load zero pools and profiles from a JSON file
Dependency: It depends on Azure/sonic-swss#1910 and submodule advancing PR once the former merged.
How I did it
Add buffer profiles and pool definition for zero buffer profiles
If the buffer model is static:
Apply normal buffer profiles to admin-up ports
Apply zero buffer profiles to admin-down ports
If the buffer model is dynamic:
Apply normal buffer profiles to all ports
buffer manager will take care when a port is shut down
Update buffers_config.j2 to support INACTIVE PORTS by extending the existing macros to generate the various buffer objects, including PGs, queues, ingress/egress profile lists
Originally, all the macros to generate the above buffer objects took active ports only as an argument
Now that buffer items need to be generated on inactive ports as well, an extra argument representing the inactive ports need to be added
To be backward compatible, a new series of macros are introduced to take both active and inactive ports as arguments
The original version (with active ports only) will be checked first. If it is not defined, then the extended version will be called
Only vendors who support zero profiles need to change their buffer templates
Enable buffer manager to load zero pools and profiles from a JSON file:
The JSON file is provided on a per-platform basis
It is copied from platform/<vendor> folder to /usr/share/sonic/temlates folder in compiling time and rendered when the swss container is being created.
To make code clean and reduce redundant code, extract common macros from buffer_defaults_t{0,1}.j2 of all SKUs to two common files:
One in Mellanox-SN2700-D48C8 for single ingress pool mode
The other in ACS-MSN2700 for double ingress pool mode
Those files of all other SKUs will be symbol link to the above files
Update sonic-cfggen test accordingly:
Adjust example output file of JSON template for unit test
Add unit test in for Mellanox's new buffer templates.
How to verify it
Regression test.
Unit test in sonic-cfggen
Run regression test and manually test.

#### How I did it
Added correct mode format in hwksu.json in Mellanox-SN2700-D40C8S8 and updated platform.json for the new mode.
#### How to verify it
Using sonic-cfggen verify it works fine
#### 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
```

QOS tables in config db used ABNF format i.e "[TABLE_NAME|name] to refer fieldvalue to other qos tables.
Example:

"wred_profile": "[WRED_PROFILE|AZURE_LOSSLESS]"

"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:

Add new platform x86_64-ragile_ra-b6910-64c-r0 (Tomahawk 3)
ASIC Vendor: Broadcom
Switch ASIC: Tomahawk 3
Port Config: 64x100G
-How I did it
Provide device and platform related files.
-How to verify it
show platform fan
show platform ssdhealth
show platform psustatus
show platform summary
show platform syseeprom
show platform temperature
show interface status
- Why I did it
SN4600 A0 platform was EOL, so there is no need to support it, sensor conf can be removed and we don't need to maintain 2 sensor conf files, only A1 platform is needed.
- How I did it
Remove get_sensors_conf_path which intends to load correct sensor conf for different(A0/A1) platforms.
Remove the sensor conf for A0 platform, rename previous sensor.conf.a1 to sensor.conf
- How to verify it
Run sensor test on the SN4600 platform.
- Disable health monitoring of `psu.voltage` until support is implemented
- chassis: disable provisioning bit once linecard has booted
- chassis: fix issue in `show version` when running as `admin`
- chassis: fix race when reading an eeprom before it's available
- chassis: implement `get_all_asics` call
- api: fix `ChassisBase.get_system_eeprom_info` implementation
- api: add missing thermal condition and info
- api: fix return value of `ChassisBase.set_status_led`
- sfp: introduce SfpOptoeBase implementation used based on configuration knob
- psu: rely on pmbus to read input/output status when other mechanism is missing
- misc: other refactors and improvements
Why I did it
End goal: To have azure pipeline job to run multi-asic VS tests.
Intermediate goal: Require multi-asic KVM image so that the test can be run.
The difference between single asic and multi-asic KVM image is asic.conf file which has different NUM_ASIC values.
Idea behind the approach in this PR to attain the intermediate goal above:
Ease of building multi-asic KVM image so that any user or azure pipeline can use a simple make command to generate single or multi-asic KVM images as required.
Use a single onie installer image and multiple KVM images for single and multi-asic images.
Current scenario:
For VS platform, sonic-vs.bin is generated which is the onie installer image and sonic-vs.img.gz is generated which is the KVM iamge.
Scenario to be achieved:
sonic-vs.bin - which will include single asic platform, 4 asic platform and 6 asic platform.
sonic-vs.img.gz - single asic KVM image
sonic-4asic-vs.img.gz - 4 asic KVM image
sonic-6asic-vs.img.gz - 6 asic KVM image
In this PR, 2 new platforms are added for 4-asic and 6-asic VS.
How I did it
Create 4-asic and 6-asic device directories with the required files and hwsku files.
Add onie-recovery image information in vs platform.
How to verify it
After this PR change, no build change.
sonic-vs.bin onie installer image should include information of new multi-asic vs platforms.
Why I did it

- How to verify it
Run show interface breakout on a MSN4410 and verify that 2x100G and 4x50G are listed in the supported breakout modes for ports 1-24.
This change introduces 3 columns in the port_config.ini file.
These are coreId, corePortId and numVoq.
The ports for inband and recirc were also renamed properly.
Why I did it

Modified the platform/broadcom/one-image.mk to include NOKIA_IXR7250_PLATFORM_MODULE
Modified the platform/broadcom/rule.mk to include the platform-module-nokia.mk
Why I did it
The SFP1 port was disabled in the default configuration.
How I did it
This commit enables the 10G front port for usage.
This was done using a DX030 together with an Arista switch using bcmsh and phy diag xe0 dsc to figure out what lane mappings make sense.
Validated on Celestica Seastone2 DX030.
How to verify it
Own a Celestica DX030
Connect the front SFP1 port to something.
It works :-)
You can do tcpdump -i Ethernet128 -n and you will see both incoming and outgoing LLDP.

Why I did it
To support dynamic port breakout Broadcom configurations on Arista platforms.
How I did it
Updated platform.json for platforms and added new hwsku, Broadcom config, and hwsku.json for dynamic port breakout usage.
The name of the new hwsku name used is very similar to the platform name (platform x86_64-arista_7050_qx32s hwsku Arista-7050QX-32S) as the flex hwsku is meant to be the default in the future.
How to verify it
Boot up device with the new hwsku, interfaces are up.
Change hwsku.json with new default breakout mode and reload device, breakout will have successfully been applied.
#### Why I did it
The values of the syseeprom were not valid
#### How I did it

#### Why I did it
New SN410 A1 system has a different sensor layout with A0 system, needs a new sensor conf file to support it.
#### How I did it
Since the SN4410 A1 system use exactly the same sensor layout as the SN4700 A1 system, so add a symbol link linking to the SN4700 A1 sensor conf file to reuse.
#### How to verify it

How to verify it
- With the default cable len set to 0m and the associated changes in swss, CABLE_LENGTH table had '0m' set for unused ports and accordingly more space was reserved for the shared pool
- Cfggen tests passed with the cable len update
Why I did it

- Why I did it
The default breakout mode according to hwsku.json for the MSN4410 is 1x400G and this is not a supported breakout mode according to its platform.json
This causes a conflict on boot of this platform and no containers on the switch will init successfully.
- How I did it
Referenced the platform specification files and updated platform.json
- How to verify it
Install master version of SONiC on MSN4410
Boot switch and verify swss is successfully running using docker ps
What I did:

#### Why I did it
- After [sonic-linux-kernel#177](https://github.com/Azure/sonic-linux-kernel/pull/177) changes, the I2C mux channels of Baseboard and Switchboard CPLDs are moved from i2c-4 and i2c-5 to i2c-36 and i2c-37 respectively.
- This caused QSFP driver initialization of i2c-36 to i2c-41 to fail causing the ports from Ethernet208 to Ethernet248 fail.
#### How I did it
- The fix to this problem is to change the order of QSFP driver initialization to I2C mux channels.
- Instead of the order i2c-10 to i2c-41, the order i2c-4 to i2c-35 is being utilized.
- Also, need to change the i2c-mux-channel number for Baseboard CPLD and switchboard CPLD in scripts to access them.
hwskus.
Why I did it
For multi-asic platforms, orchagent process in swss docker is started by passing device_ids(or asic_ids).
Each swss docker starts orchagent with a different device_id. This device_id is passed as Hardware info to syncd. For syncd to start with the right hwinfo, context_config.json is passed as an argument. context_config.json file is looked up to get the hwinfo information.
sonic-sairedis PRs required for this diff to be used to bring up multi-asic VS:
Azure/sonic-sairedis#830Azure/sonic-sairedis#832
How I did it
Add context_config.json for each asic in the same structure as provided here: https://github.com/Azure/sonic-sairedis/blob/master/lib/src/context_config.json
Each asic context_config.json will have different hwinfo string.
hwinfo string will be same as device id retrieved from asic.conf file.
