| ## 1 Requirements Overview | ||
| SONiC OS is portable across different network devices with supported ASIC via Switch Abstraction Interface (SAI). These devices primarily differ in the way various device specific hardware components are accessed, and thus require custom device drivers and python plugins. Each platform vendor implements these custom device drivers and plugins. The feature requirement is to support a SONiC platform driver development framework to enable rapid development of custom device drivers and plugins. | ||

Currently SONiC is in the process to replace platform plugin with a newly designed platform APIs, the target is to switch to new platform API in 201908 release, so should also considering to support platform API for the coming transform. The design doc of new platform API is here: #285 the new platform base class is defined here: https://github.com/Azure/sonic-platform-common/tree/master/sonic_platform_base

Hi Kebo Liu,
Yes, we are aware of the new platform API in August, 2019 release. We plan to support new platform base class in PDDF.

@fk410167: Do you have plans to update this document to reflect the new platform API? Vendors are currently in the process of migrating over to the new API. At this point in time, this document should reflect the new API rather than the old plugins.

Yes we have already started to move the whole framework to use 2.0 platform APIs. We will modify the HLD accordingly.

@fk410167 assuming platform vendor will use its own drivers and not using generic drivers with JSON descriptor files approach, how can vendor use generic plugin/platform API implementation by providing sysfs path or symlink to sysfs and attributes list? |
