From 005b7f7f93b44ffd93f337c216ddb44d8a7c276b Mon Sep 17 00:00:00 2001 From: Likun Gao Date: Thu, 10 Jul 2025 14:25:03 +0800 Subject: [PATCH] drm/amdgpu: correct rlc autoload for xcc harvest If the number instances of firmware is RLC_NUM_INS_CODE0(Only 1 inst), need to copy it directly for rlcautolad. For the firmware which instances number bigger than 1, only copy for enabled XCC to save copy time.
