From e6a1fe50c1e63fb0dcedba58180c1ac5aae756b7 Mon Sep 17 00:00:00 2001 From: Srinivasan Shanmugam Date: Fri, 18 Apr 2025 00:57:19 +0530 Subject: drm/amd/display: Add NULL pointer checks in dm_force_atomic_commit() [ Upstream commit 3f397cd203f247879c2f1a061e90d4c8d23655de ] This commit updates the dm_force_atomic_commit function to replace the usage of PTR_ERR_OR_ZERO with IS_ERR for checking error states after retrieving the Connector (drm_atomic_get_connector_state), CRTC (drm_atomic_get_crtc_state), and Plane (drm_atomic_get_plane_state) states. The function utilized PTR_ERR_OR_ZERO for error checking. However, this approach is inappropriate in this context because the respective functions do not return NULL; they return pointers that encode errors. This change ensures that error pointers are properly checked using IS_ERR before attempting to dereference.

Currently it considered common dsc config is found if max and min target bpp are non zero which is not accurate. Invalid max and min target bpp values would not get max_kbps and min_kbps calculated, leading to falsefully pass a mode that does not have valid dsc parameters available. [how] Use the return value of decide_dsc_bandwidth_range() to determine whether valid dsc common config is found or not. Prune out modes that do not have valid common dsc config determined.
