In preparation for the merging of Azure/sonic-platform-common#173, which properly defines class and instance members in the Platform API base classes.
It is proper object-oriented methodology to call the base class initializer, even if it is only the default initializer. This also future-proofs the potential addition of custom initializers in the base classes down the road.
#### Why I did it
To incorporate the below changes in DellEMC S5232, Z9264, Z9332 platforms.
- Update thermal high threshold values
- Make watchdog API Python2 and Python3 compatible
- Fix LGTM alerts
- Z9264: Fix get_change_event timer value
#### How I did it
- Use 'universal_newlines=True' in subprocess.Popen call.
- Change the timeout in 'get_change_event' to milliseconds to match specification in sonic_platform_common/chassis_base.py
- Fix parent `__init__` call for platform API, based on Azure/sonic-platform-common#173
- Implementation for more platform API methods
- Daily storage information reporting in `arista daemon`
- Enhancements to reboot cause reporting, now multi-sourcing reboot cause information
- Miscellaneous fixes
The S6000 devices, the cold reboot is abrupt and it is likely to cause issues which will cause the device to land into EFI shell. Hence the platform reboot will happen after graceful unmount of all the filesystems as in S6100.
Moved the platform_reboot to platform_reboot_override and hooked it to the systemd shutdown services as in S6100
- Add support for `DCS-7050SX3-48YC8` and `DCS-7050SX3-48C8` platform
- Add support for more variants of `DCS-7280CR3-32[PD]4`
- Add Supervisor to Linecard consutil support
- Complete Watchdog platform API support
- Fix some PSU behavior on `DCS-7050QX-32` and `DCS-7060CX-32S`
- Fix SEU management on `DCS-7060CX-32S`
- Allow kernel modules to build up to linux 5.10
- Rename led color `orange` to `amber`
- Miscellaneous fixes
Azure/sonic-utilities#1431 changes the path to the udevprefix.conf file. The file previously inappropriately resided in the <platform>/plugins/ directory. That directory is reserved for now-deprecated Python platform plugins, and will be removed in the near future.
This PR is needed to fix the show interface counters output issue where the counters are not correct due to an issue introduced in BRCM SAI 4.3.
- How to verify it
Without the fix if one injects packets, the expected counters for the interfaces involved do not show correct count values. The RX count looks to be TX count while TX count looks to be RX count but even that the values could not be trusted.
After the fix the counters started to look correct. Here is one sample output taken after the fix is applied where I manually injected 10,000 packets into Ethernet92 to be routed out of the port channel member port Ethernet40. Also injected 10,000 invalid packets into the same Ethernet92 and all 10,000 packets were shown RX_DRP correctly.

**- Why I did it**
PR https://github.com/Azure/sonic-platform-common/pull/102 modified the name of the SFF-8436 (QSFP) method to align the method name between all drivers, renaming it from `parse_qsfp_dom_capability` to `parse_dom_capability`. Once the submodule was updated, the callers using the old nomenclature broke. This PR updates all callers to use the new naming convention.
**- How I did it**
Update the name of the function globally for all calls into the SFF-8436 driver.
Note that the QSFP-DD driver still uses the old nomenclature and should be modified similarly. I will open a PR to handle this separately.
**- Why I did it**
To incorporate the below changes in DellEMC S6100, S6000 platforms.
- S6100, S6000:
- Enable 'thermalctld'
- Implement DeviceBase methods (presence, status, model, serial) for Fantray and Component
- Implement ‘get_position_in_parent’, ‘is_replaceable’ methods for all device types
- Implement ‘get_status’ method for Fantray
- Implement ‘get_temperature’, ‘get_temperature_high_threshold’, ‘get_voltage_high_threshold’, ‘get_voltage_low_threshold’ methods for PSU
- Implement ‘get_status_led’, ‘set_status_led’ methods for Chassis
- SFP:
- Make EEPROM read both Python2 and Python3 compatible
- Fix ‘get_tx_disable_channel’ method’s return type
- Implement ‘tx_disable’, ‘tx_disable_channel’ and ‘set_power_override’ methods
- S6000:
- Move PSU thermal sensors from Chassis to respective PSU
- Make available the data of both Fans present in each Fantray
**- How I did it**
- Remove 'skip_thermalctld:true' in pmon_daemon_control.json
- Implement the platform API methods in the respective device files
- Use `bytearray` for data read from transceiver EEPROM
- Change return type of 'get_tx_disable_channel' to match specification in sonic_platform_common/sfp_base.py
1. BRCM SAI Debian build need not have any Kernel version dependency - Starting with 4.3 BRCM made changes in SAI so that this dependency has been cleaned up. We can now remove the Kernel Version dependency from Azure Pipeline build script.
2. Bypass PEER_MODE p2mp setting causing SYNCd crash on non-TD3 SKUs - Temporarily patch BRCM SAI code to not cause SYNCd crash when Orchagent program SAI_TUNNEL_ATTR_PEER_MODE: SAI_TUNNEL_PEER_MODE_P2MP on Non-TD3 SKUs. Will remove this when BRCM provide proper fix to address this issue.
- Why I did it
Fix issue: ptf_nn_agent isn't able to start in syncd-rpc docker on buster.
- How I did it
The issue is fixed by installing python-dev, cffi and nnpy for python 2 explicitly.
- How to verify it
Run copp test on RPC image.
Starting with BRCM SAI 4.3.1.5 we see the following :ethtool not fount" error in syslog during boot up:

It seems that starting with BRCM SAI 4.2.1.5 syncd is using ethtool to set the host interface speed and since this ethtool was not part of the syncd Docker, we observe these "ethtool not found" issue.

- Why I did it
Initially, we used Monit to monitor critical processes in each container. If one of critical processes was not running
or crashed due to some reasons, then Monit will write an alerting message into syslog periodically. If we add a new process
in a container, the corresponding Monti configuration file will also need to update. It is a little hard for maintenance.
Currently we employed event listener of Supervisod to do this monitoring. Since processes in each container are managed by
Supervisord, we can only focus on the logic of monitoring.
- How I did it
We borrowed the event listener of Supervisord to monitor critical processes in containers. The event listener will take
following steps if it was notified one of critical processes exited unexpectedly:
The event listener will first check whether the auto-restart mechanism was enabled for this container or not. If auto-restart mechanism was enabled, event listener will kill the Supervisord process, which should cause the container to exit and subsequently get restarted.
If auto-restart mechanism was not enabled for this contianer, the event listener will enter a loop which will first sleep 1 minute and then check whether the process is running. If yes, the event listener exits. If no, an alerting message will be written into syslog.
- How to verify it
First, we need checked whether the auto-restart mechanism of a container was enabled or not by running the command show feature status. If enabled, one critical process should be selected and killed manually, then we need check whether the container will be restarted or not.
Second, we can disable the auto-restart mechanism if it was enabled at step 1 by running the commnad sudo config feature autorestart <container_name> disabled. Then one critical process should be selected and killed. After that, we will see the alerting message which will appear in the syslog every 1 minute.

Fix#119
when parallel build is enable, multiple dpkg-buildpackage
instances are running at the same time. /var/lib/dpkg is shared
by all instances and the /var/lib/dpkg/updates could be corrupted
and cause the build failure.
the fix is to use overlay fs to mount separate /var/lib/dpkg
for each dpkg-buildpackage instance so that they are not affecting
each other.

Starting from build (master) 176 the warm reboot on BRCM Platform started to experience syncd crash. Upon further debug by Ying it was determined that the crash was related to the following new change:
[Dynamic buffer calc] Support dynamic buffer calculation (#1338)
Ying also debugged further and found The crash was caused by buffer pool profile setting operation SAI_BUFFER_PROFILE_ATTR_SHARED_DYNAMIC_TH
A case has filed with BRCM while a potential fix was tried by Ying that seems to have addressed this issue and we are making this change available in master branch so that it will allow further feature validation/testing especially in the warm reboot area.
Once an official fix is provided by BRCM, we will then remove this in house fix and apply the official fix.
- How to verify it
Just perform warm reboot with any master code 175 or above you should see this issue or issue the following cmd will also cause the crash: "mmuconfig -p egress_lossy_profile -a 0"
- Dynamically change EEPROM driver based on media type.
- Otherwise, EEPROM INFO and DOM INFO might not be fetched properly and will result in erroneous output.
Add a systemd dependency to make platform-modules service as a prerequisite for determine-reboot-cause service to ensure platform initialization is complete before determine-reboot-cause.service executes.

- Replace print statement with print function in eeprom.py plugin for x86_64-kvm_x86_64-r0 platform
- Update all platform plugins to be compatible with both Python 2 and Python 3
- Remove shebangs from plugins files which are not intended to be executable
- Replace tabs with spaces in Python plugin files and fix alignment, because Python 3 is more strict
- Remove trailing whitespace from plugins files
Some syncd containers are still based on Debian Stretch, and thus do not have Python 3 available. For these containers, we must still rely on Python 2 to run supervisord_dependent_startup and supervisor-proc-exit-listener.

**- Why I did it**
We were building a custom version of Supervisor because I had added patches to prevent hangs and crashes if the system clock ever rolled backward. Those changes were merged into the upstream Supervisor repo as of version 3.4.0 (http://supervisord.org/changes.html#id9), therefore, we should be able to simply install the vanilla package via pip. This will also allow us to easily move to Python 3, as Python 3 support was added in version 4.0.0.
**- How I did it**
- Remove Makefiles and patches for building supervisor package from source
- Install Python 3 supervisor package version 4.2.1 in Buster base container
- Also install Python 3 version of supervisord-dependent-startup in Buster base container
- Debian package installed binary in `/usr/bin/`, but pip package installs in `/usr/local/bin/`, so rather than update all absolute paths, I changed all references to simply call `supervisord` and let the system PATH find the executable to prevent future need for changes just in case we ever need to switch back to build a Debian package, then we won't need to modify these again.
- Install Python 2 supervisor package >= 3.4.0 in Stretch and Jessie base containers

This change introduces PDDF which is described here: https://github.com/Azure/SONiC/pull/536
Most of the platform bring up effort goes in developing the platform device drivers, SONiC platform APIs and validating them. Typically each platform vendor writes their own drivers and platform APIs which is very tailor made to that platform. This involves writing code, building, installing it on the target platform devices and testing. Many of the details of the platform are hard coded into these drivers, from the HW spec. They go through this cycle repetitively till everything works fine, and is validated before upstreaming the code.
PDDF aims to make this platform driver and platform APIs development process much simpler by providing a data driven development framework. This is enabled by:
JSON descriptor files for platform data
Generic data-driven drivers for various devices
Generic SONiC platform APIs
Vendor specific extensions for customisation and extensibility

Recently PCA9541 driver was added to the kernel and since then
the initialization takes effect and has negatively impacted the
platform stability.
Commenting the initialization code out to restore the original
behavior while analyzing further.

Why/How I did:
Make sure first error syslog is triggered based on FAULT TOLERANCE condition.
Added support of repeat clause with alert action. This is used as trigger
for generation of periodic syslog error messages if error is persistent
Updated the monit conf files with repeat every x cycles for the alert action
