From ddb267b66af9d49d54e3d3ce8a6b4e4e7ad9af0a Mon Sep 17 00:00:00 2001 From: Yann Dirson Date: Mon, 29 Nov 2021 21:08:57 +0100 Subject: [PATCH] drm/amdgpu: update fw_load_type module parameter doc to match code amdgpu_ucode_get_load_type() does not interpret this parameter as documented. It is ignored for many ASIC types (which presumably only support one load_type), and when not ignored it is only used to force direct loading instead of PSP loading. SMU loading is only available for ASICs for which the parameter is ignored.
