- Why I did it
to prevent python exception error when executing warm-reboot command on mellanox simulator platform
- How I did it
return None on the watchdog python script on cases that watchdog file is not exist
- How to verify it
warm-reboot is running well without the python error. error message will appear on log on these cases.
in order to avoid this error message we can simulate the watchdog on mellanox simulator platform
- Removed the old function for detecting a faulty fan.
- Removed the old function for detecting excess temperature.
- Implement thermal_manager APIs based on ThermalManagerBase
- Implement thermal_conditions APIs based on ThermalPolicyConditionBase
- Implement thermal_actions APIs based on ThermalPolicyActionBase
- Implement thermal_info APIs based on ThermalPolicyInfoBase
- Add thermal_policy.json
Why I did it
To determine the revision of the pcie.yaml to be used based on BIOS version in DellEMC S6100 platform.
Depends on: Azure/sonic-platform-common#195
How I did it
Added two revisions of pcie.yaml pcie_1.yaml and pcie_2.yaml
Included a platform-specific Pcie class to provide the revision of the pcie.yaml to be used by pcieutil/pcied.
How to verify it
Execute pcieutil check (Azure/sonic-utilities#1672) command and verify the list of PCIe devices displayed.
Logs: UT_logs.txt
Use udevadm to trigger the udev rules on the first boot
How to verify:
- Connect C0 with E1031;
- Install or upgrade the sonic os to 202012 branch;
- When access to sonic check if /dev/C0-1 to /dev/C0-48 are existed.
Update FW version to 2008.3218, fixing the following issues:
- 50G/100G links that are operationally down before warm-reboot are not coming up after warm-reboot
- 50G/100G links with admin shut / no shut commands are not coming up after warm-reboot

- Changes and new features:
1. Added support in SN4600C systems for new module Finisar ET7402-CWDM4 (100G CWDM4 QSFP28 1310nm SM 2KM).
2. Added support for new module MMS1W50-HM (2km transceiver FR4) for 200GbE
3. Improved performance of "per-port-buffer" counters
4. Added support for Kernel 5.10
- Bug fix:
On rare occasions (0.5%), in SN4600C systems, when using 100GbE NRZ mode and Fastboot flow, the link up time may take up to 10 seconds

Why I did it
There were two regression issues introduced by BRCM SAI 4.3.3.8:
CS00012196056 [4.3.3.8][WARMBOOT] syncd[2584]: segfault at 5616ad6c3d80 ip 00007f61e0c6bc65 sp 00007fff0c5a7a90 error 4 in libsai.so.1.0[7f61e0a95000+3cd8000]
CS00012195956 [4.3.3.8] [TD3]Syncd Crash at brcm_sai_tnl_mp_create_tunnel()
How I did it
Patch for CS00012195956 from BRCM was validated to have addressed the tunnel creation issue.
Temporary worked around the issue by commenting out a portion of questionable code in BRCM SAI that seems to be the root cause of CS00012196056 .
How to verify it
See the BRCM cases for details.

#### Why I did it

#### How I did it
Call PSUBase class initializer from derived class
There was an issue on master where `thermal.get_position_in_parent` in the platform API was returning -1 instead of a proper index. This is a backport of the fix for that issue.
- Why I did it
This is to back-port Azure 7410 to 202012 branch.
Enhance the Python3 support for platform API. Originally, some platform APIs call SDK API which didn't support Python 3. Now the Python 3 APIs have been supported in SDK 4.4.3XXX, Python3 is completely supported by platform API
- How I did it
Start all platform daemons from python3
1. Remove #/usr/bin/env python at the beginning of each platform API file as the platform API won't be started as daemons but be imported from other daemons.
2. Adjust SDK API calls accordingly

Why I did it
Currently we leveraged the Supervisor to monitor the running status of critical processes in each container and it is more reliable and flexible than doing the monitoring by Monit. So we removed the functionality of monitoring the critical processes by Monit.
How I did it
I removed the script process_checker and corresponding Monit configuration entries of critical processes.
How to verify it
I verified this on the device str-7260cx3-acs-1.
This is due to the fact that we use SONIC_OVERRIDE_BUILD_VARS internally
in our build jobs and this is not accounted in caching framework.
So we add MLNX_SDK_DEB_VERSION to force rebuild if we changed it via
SONIC_OVERRIDE_BUILD_VARS.

#### 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.
#### Why I did it
On our platforms syncd must be up while using the sonic_platform.
The issue is warm-reboot script first disables syncd then instantiate Chassis, which tries to connect syncd in __init__.
#### How I did it
Refactor Chassis to lazy initialize components.
