Shared tracing hooks that GPU drivers across the kernel use to report memory allocation events to the Linux tracing subsystem. It is plumbing for performance analysis tools, not code that talks to any specific piece of hardware.
This is not actually a driver directory; it is a small piece of cross-cutting infrastructure that exposes GPU memory tracepoints for other drivers and userspace tracing tools to consume. There is no hardware to support or deprecate here.

codex reasoning notes (technical)
Not a driver directory: contains generic GPU memory tracepoint infrastructure (Kconfig/Makefile plus tracepoint export code), not kernel-bound hardware driver code.
