AMD DCN 2.0 Display Mode Library support code

Helper code inside the AMDGPU display stack that performs the bandwidth, watermark, and pipe-allocation calculations needed to drive AMD's DCN 2.0 display hardware (the display engine in Navi-generation Radeon GPUs from around 2019). It is a math and validation library used by the larger AMD display driver, not a driver that binds to hardware on its own.

recommendation

This is not a standalone driver; it is an internal subcomponent of the AMDGPU display core (DC) that implements the DCN 2.0 Display Mode Library used to compute display timings and memory bandwidth for Navi-class Radeon GPUs. It lives or dies with the broader AMD display driver and should not be evaluated for removal in isolation.

codex reasoning notes (technical)

Not a driver directory: contains AMD DCN2.0 display-mode-library support code under the AMDGPU display stack, not a standalone kernel-bound hardware driver.
