AMD DCN 3.0 Display Writeback Block Helpers

Internal support code for the display writeback hardware block in AMD's DCN 3.0 display engine, used by GPUs like the Navi 2x / RDNA 2 family (Radeon RX 6000 series and related APUs). Writeback lets the display pipeline capture the composed framebuffer back to memory, which is used for things like wireless display, screen recording, and compositor effects.

recommendation

This is not a standalone driver but a subdirectory of helper code inside the amdgpu display core (DC) that implements one specific hardware block on DCN 3.0 GPUs. It lives or dies with the broader amdgpu driver and is not a meaningful unit to evaluate for keep/remove on its own.

codex reasoning notes (technical)

Not a driver directory: AMD DCN3.0 display writeback block support nested under the amdgpu display stack, i.e. an internal helper/hardware-block implementation rather than a standalone kernel-bound driver.
