[PATCH v3 10/11] drm/amd: Request GFX11 microcode during IP discovery
From: Mario Limonciello
Date: Fri Dec 30 2022 - 00:22:47 EST
If GFX11 microcode is required but not available during early init, the
firmware framebuffer will have already been released and the screen will
freeze.
Move the request for GFX11 microcode into the IP discovery phase
so that if it's not available, IP discovery will fail.
