==========
Guidelines
==========

This documents contains the guidelines for nova-core. Additionally, all common
guidelines of the Nova project do apply.

Driver API
==========

One main purpose of nova-core is to implement the abstraction around the
firmware interface of GSP and provide a firmware (version) independent API for
2nd level drivers, such as nova-drm or the vGPU manager VFIO driver.

Therefore, it is not permitted to leak firmware (version) specifics, through the
driver API, to 2nd level drivers.

Acceptance Criteria
===================

- To the extend possible, patches submitted to nova-core must be tested for
  regressions with all 2nd level drivers.
