Subject: [PATCH 08/17] drm/amd/display: Toggle VSR button cause system crash
Date: Fri, 7 Feb 2020 10:50:01 -0500 [thread overview]
Message-ID: <20200207155010.1070737-9-Rodrigo.Siqueira@amd.com> (raw)
In-Reply-To: <20200207155010.1070737-1-Rodrigo.Siqueira@amd.com>
From: Peikang Zhang <peikang.zhang@amd.com>
[Why]
in dcn10_apply_ctx_for_surface(), if we hit !top_pipe_to_program,
pipe_ctx->update_flags could not get cleared.
[How]
Moved clearing pipe_ctx->update_flags logic before if
(!top_pipe_to_program) to gurantee pipe_ctx->update_flags get cleared.
