From 15df736afe009856a40baf93df3fd10f4a32a88b Mon Sep 17 00:00:00 2001 From: Boyuan Zhang Date: Wed, 2 Oct 2024 21:59:33 -0400 Subject: [PATCH 1079/5403] drm/amd/pm: add inst to smu_dpm_set_vcn_enable MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit First, add an instance parameter to smu_dpm_set_vcn_enable() function, and calling dpm_set_vcn_enable() with this given instance. Second, modify vcn_gated to be an array, to track the gating status for each vcn instance separately. With these 2 changes, smu_dpm_set_vcn_enable() will check and set the gating status for the given vcn instance ONLY. v2: remove duplicated functions. remove for-loop in dpm_set_vcn_enable(), and temporarily move it to to smu_dpm_set_power_gate(), in order to keep the exact same logic as before, until further separation in next patch. v3: add instance number in error message. v4: declaring i at the top of the function.
