Why I did it
serial-getty service exited in Dell S6100 device randomly.
How I did it
Added serial-getty to monit services.
How to verify it
Stop serial-getty in ssh session and check whether the service restarts or not
Why I did it
To handle newer SSD firmware version in DellEMC S6100 platform (S210506G - 3IE devices).
How I did it
Update s6100_ssd_upgrade_status.sh to handle newer SSD firmware version.
How to verify it
Logs: UT_logs.txt
Why I did it
To recover the SSD upgrade state in case, if ONIE-uninstall or ssd_fw_upgrade folder got deleted.
To handle newer SSD version(S21506G - 3IE GPIO7 low devices).
Also correcting the error messages for non-upgraded S6100s.
Why I did it
Added soft-reboot plugin support.
Added SSD version s16425cq check
Added error message to display in console/SSH in case reboot is called in faulty/non-upgraded devices.
Why I did it
To monitor the SSD health condition in DellEMC S6100 platform post upgrade.
A daemon is introduced to monitor the SSD every one hour.
To check for SSD status at boot time and at the time of cold-reboot.
All these changes are supported only for newer SSD firmware.
Added a platform_reboot_pre_check script to prevent cold-reboot based on SSD status.
Depends on Azure/sonic-utilities#1472
DO NOT MERGE UNTIL ABOVE PR IS MERGED
- Why I did it
For fixing PCA MUX attachment issue in Dell S6100 platform.
- How I did it
Wait till IOM MUX powered up properly and start I2C enumeration.
Align SFP key names with new standard defined in https://github.com/Azure/sonic-platform-common/pull/97
- hardwarerev -> hardware_rev
- serialnum -> serial
- manufacturename -> manufacturer
- modelname -> model
- Connector -> connector
- Xilinx/pericom peripherals are not actively used in DellEMC S6100 switch.
- These peripherals are throwing PCIE corrected messages in some of the units and filling syslog.
- Since it is not usable disabling it at startup.
**- Why I did it**
- Skip thermalctld in DellEMC S6000, S6100, Z9100 and Z9264 platforms.
- Change the return type of thermal Platform APIs in DellEMC S6000, S6100 and Z9100 platforms to 'float'.
**- How I did it**
- Add 'skip_thermalctld:true' in pmon_daemon_control.json for DellEMC S6000, S6100, Z9100 and Z9264 platforms.
- Made changes in thermal.py, for 'get_temperature', 'get_high_threshold' and 'get_low_threshold' to return 'float' value.
**- How to verify it**
- Check thermalctld is not running in 'pmon'.
- Wrote a python script to load Chassis class and then call the APIs accordingly and verify the return type.
For detecting transceiver change events through xcvrd in DellEMC S6000, S6100 and Z9100 platforms.
- In S6000, rename 'get_transceiver_change_event' in chassis.py to 'get_change_event' and return appropriate values.
- In S6100, implement 'get_change_event' through polling method (poll interval = 1 second) in chassis.py (Transceiver insertion/removal does not generate interrupts due to a CPLD bug)
- In Z9100, implement 'get_change_event' through interrupt method using select.epoll().
- 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.
Implement Watchdog platform2.0 API for DellEMC S6100 platform.
- Added new file watchdog.py in sonic_platform directory.
- Enabled API support to Enable/disable watchdog.
Implemented remaining APIs in s6100,z9100,s6000
Removed soft link in s6100,s6000,z9100 and implemented seperately
Implemented get_transceiver_change_event in S6000
* [DELL][Z9100,S6100,S6000] Platform 2.0 SFP Changes
Added support in sfp.py file which will be generic. Send the eeprom path and sfp_control path from chassis.py
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
- import sonic_platform
+ import sonic_platform.platform
The following commit addresses the graceful unmounting of file
system and graceful shutdown of dockers before calling a
cold reboot which will cause a power cycle of SSD. This ensures
orderly shutdown and no corruption of files systems because
of the power cycle to SSD.
This commit will use the existing systemd-reboot service scripts
and override the configuration to do cold reboot for S6100 and
Z9100.
Unit tested the fix and graceful shutdown of file system and
dockers are done with cold reboot.

- What I did
Added Daemon to Log LPC bus degradation in Intel C2000 processor. Intel Rangeley C2000 processors with revision less than or equal to 2 have issue where LPC bus degrades over time in some processors. To identify the problem and to notify the issue, a daemon has been added which will log on encountering the issue.
- How I did it
Added a daemon which validates the CPLD scratch(0x102) and SMF scratch(0x202) registers by writing and reading values on regular polling intervals (300 seconds). If there is a discrepancy between read and write, a critical log will be thrown.
- How to verify it
The infra is verify by simulating the issue where between write and read, the value in register is modified and the log appearance is checked.
- Description for the changelog
Added Daemon to identify LPC bus degradation issue and notify using syslog in Dell S6100 and Z9100 platforms. This daemon will only run on processors with revision less than or equal to 2.
