From c44af3810fc8b3adf6910a332038aa566560c8fa Mon Sep 17 00:00:00 2001 From: Boyuan Zhang Date: Fri, 26 Jun 2026 10:39:26 -0400 Subject: [PATCH] drm/amdgpu/jpeg: fix jpeg_v4_0_3_is_idle detection jpeg_v4_0_3_is_idle() initializes ret to false and then accumulates ring idle status using &=. Since false & condition always remains false, the function can never report the JPEG block as idle. Initialize ret to true so the function returns true only when all JPEG rings report RB_JOB_DONE.
