+=== Enabling  ROCm & HIP For Packages ===
-For running Blender with HIP support, see: [[Blender#HIP]].
+Whether or not a package is built with ROCm support is controlled by the <code>rocmSupport</code> nixpkgs config variable. As HIP is a component of ROCm, anything that needs HIP support (e.g. Blender) gets that enabled through <code>rocmSupport</code> too.

Smudgebun: /* Blender */ Replace the (outdated as of https://github.com/NixOS/nixpkgs/pull/463064) Blender HIP information with a link to the HIP section of the Blender page. Goal is to centralize Blender information to one place to make keeping it up-to-date it easier.

	This guide is about ~~setting up~~ NixOS to correctly use ~~your~~ AMD ~~Graphics card if it is relatively new (aka, after~~ the ~~GCN architecture)~~.		[https://en.wikipedia.org/wiki/AMDgpu_(Linux_kernel_module) AMDGPU] is an open source graphics driver for AMD Radeon graphics cards. It supports AMD GPUs based on the [https://en.wikipedia.org/wiki/Graphics_Core_Next GCN architecture Graphics Core Next (GCN)] architecture and later, covering hardware released from approximately 2012 onward. This guide is about configuration of NixOS to correctly use AMD GPUs supported by the AMDGPU driver.
