Why I did it
To implement fan control using thermalctld in DellEMC S6000 platform
Requires: Azure/sonic-linux-kernel#241
How I did it
Add thermal policies in 'thermal_policy.json'
Implemented thermal_manager.py and the necessary modules to perform fan control via thermalctld
Removed fancontrol.sh
How to verify it
Verified that the fan speeds are set based on the fan and temperature status.
Logs: S6000_fan_control_test_logs.txt
Why I did it
PCIe Gen1 settings was needed for Dell S6000 device.
How I did it
Modified from Gen2 to Gen 1 speed for Dell S6000 PCIe devices
How to verify it
Check lspci output, verify the syslogs
- Why I did it
To collect platform based logs along with "show techsupport" on S6000 and S6100 plaforms.
- How I did it
On branch dell_techsupport_dump

- How to verify it
hw-mgmt-dump.tar.gz will be found in sonic_dump__< YYYYMMDD_HHMMSS>.tar.gz.
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
- Make DellEMC platform modules Python3 compliant.
- Change return type of PSU Platform APIs in DellEMC Z9264, S5232 and Thermal Platform APIs in S5232 to 'float'.
- Remove multiple copies of pcisysfs.py.
- PEP8 style changes for utility scripts.
- Build and install Python3 version of sonic_platform package.
- Fix minor Platform API issues.
* [platform] Add Support For Environment Variable
This PR adds the ability to read environment file from /etc/sonic.
the file contains immutable SONiC config attributes such as platform,
hwsku, version, device_type. The aim is to minimize calls being made
into sonic-cfggen during boot time.

- Added support for Thermal event in Last Reboot Reason "show reboot-cause" command.
- Added support for sending log message in case of thermal shutdown.
sonic NOTICE root: Shutting down due to over temperature (40 degree, 30 degree, 34 degree)
- Implemented fancontrol service to monitor S6000 fans and adjust fan speed w.r.t temperature.
- fancontrol.service starts the fancontrol script at startup.
- This script takes the average temperature by reading three sensors and configure FANS to appropritate RPM against the temperature.
- When the temperature is adjusted script will log in syslog for future reference.
- Also, script checks for faulty fans and report the status in syslog.
- optoe driver truncates invalid pages(ff) but sff driver doesn't truncate.so,the DOM related calculation made by sff8436 driver will show incorrect data.
- Few optics doesn't support DOM.
- SFP plugins currently returns None for unreadable pages and this'd throw the below mentioned error in sfpshow eeprom --dom.
Added Reboot Reason for S6000 in platform 2.0
Fixed issue in process-reboot-cause
Added package uninstall code in platform de-init code for z9100, s6100
- How I did it
-> Added support for S6000 Reboot Reason
-> Added platform.py for all platforms
-> Verified show reboot-cause command with the code changes. Added UT logs with show reboot-cause
-> Modified process-reboot-cause service to start after pmon.service. In S6000, we have to wait for nvram to be loaded.
-> If reboot-cause service starts before pmon.service, show reboot-cause is showing incorrect reason.
-> Bug fix in process-reboot-cause file
