- Consolidating multiple read functions in a PSU driver on the basis of byte, word or block read,
- Enhancing PDDF parsing script support for CPU and PCH temperature reading,
- Adding missing methods in PDDF common APIs
Why I did it
- PSU driver changes are to optimize the code and increase the code coverage
- PDDF parser script enhancements to accommodate the CPU and PCH temp reading using hwmon device path
- Some of the new APIs were missing from the PDDF common platform classes
How I did it
Added code changes and verified them on AS7816 adn AS7726 platforms.
* Adding support for get/set low pwer mode for QSFPs in PDDF common APIs
* Adding support for get/set low pwer mode for QSFPs in PDDF common APIs - Review comments
Why I did it
fan_drawer support was missing in PDDF common platform APIs. This resulted in 'thermalctld' not working and 'show platform fan' and 'show platfomr temperature' commands not working.
_thermal_list array inside PSU class was not initialized. Made changes to attach the PSU related thermal sensors in the PSU instance.
How I did it
Added a common class pddf_fan_drawer.py. This class uses the PDDF JSON to fetch the platform specific data. A platform which uses PDDF would follow the below hierarchy.
fan_drawer_base.py ---> pddf_fan_drawer.py ---> fan_drawer.py
How to verify it
Run the 'show platform fan' and 'show platform temperature' commands and check the o/p.

Why I did it
Some platforms need to run few steps before the PDDF service is actually started.
* Adding pre_pddf_init script in the service file
* Raising exception for get_target_speed() for PSU-fan in PDDF (#8129)
- Why I did it
PDDF utils were python2 compliant and they needed to be migrated to Python3 (as per Bullseye)
PDDF common platform APIs file name changed as the name was already in use
Indentation issues
Dead/redundant code needed to be removed
- How I did it
Made files Python3 compliant
Indentation corrected
Redundant code removed
- How to verify it
AS7326 Accton platform uses PDDF. PDDF utils were run on this platform to verify.
#### Why I did it
- Python3 compatibility changes for PDDF eeprom class
- Adding API for temperature in PDDF psu class
- PEP8 standard changes and adding missing method in PDDF sfp class
#### How I did it
- Using python3 to invoke the sonic_platform module in PDDF based platform
- Running autopep8 tool to comply to PEP8 standards
- Made python2 to python3 changes
- Removed ord() func as python3 return int instead of str
- Had to change chr(..) to bytes([..]) function while using ctypes class methods
**- 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.
- Make PDDF code compliant with both Python 2 and Python 3
- Align code with PEP8 standards using autopep8
- Build and install both Python 2 and Python 3 PDDF packages

- Also fix Python 3-related issues:
- Use integer (floor) division in config_samples.py (sonic-config-engine)
- 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
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
