From 1f5df537fa7910a6bdc96a7cb73c65fd30e2aab5 Mon Sep 17 00:00:00 2001 From: =?utf8?q?Jouni=20H=C3=B6gander?= Date: Thu, 4 Dec 2025 09:07:16 +0200 Subject: [PATCH] drm/i915/psr: Set plane id bit in crtc_state->async_flip_planes for PSR MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit Currently plane id bit is set in crtc_state->async_flip_planes only when async flip toggle workaround is needed. We want to utilize crtc_state->async_flip_planes further in Selective Fetch calculation. v2: - rework if-else if to if-if - added comment updated Signed-off-by: Jouni Högander Reviewed-by: Ville Syrjälä Link: https://patch.msgid.link/20251204070718.1090778-2-jouni.hogander@intel.com --- drivers/gpu/drm/i915/display/intel_plane.c | 10 ++++++---- 1 file changed, 6 insertions(+), 4 deletions(-) diff --git a/drivers/gpu/drm/i915/display/intel_plane.c b/drivers/gpu/drm/i915/display/intel_plane.c index 36849cd56c02..ca9449589161 100644 --- a/drivers/gpu/drm/i915/display/intel_plane.c +++ b/drivers/gpu/drm/i915/display/intel_plane.c @@ -655,11 +655,10 @@ static int intel_plane_atomic_calc_changes(const struct intel_crtc_state *old_cr ilk_must_disable_cxsr(new_crtc_state, old_plane_state, new_plane_state)) new_crtc_state->disable_cxsr = true; - if (intel_plane_do_async_flip(plane, old_crtc_state, new_crtc_state)) { + if (intel_plane_do_async_flip(plane, old_crtc_state, new_crtc_state)) new_crtc_state->do_async_flip = true; - new_crtc_state->async_flip_planes |= BIT(plane->id); - } else if (plane->need_async_flip_toggle_wa && - new_crtc_state->uapi.async_flip) { + + if (new_crtc_state->uapi.async_flip) { /* * On platforms with double buffered async flip bit we * set the bit already one frame early during the sync @@ -667,6 +666,9 @@ static int intel_plane_atomic_calc_changes(const struct intel_crtc_state *old_cr * hardware will therefore be ready to perform a real * async flip during the next commit, without having * to wait yet another frame for the bit to latch. + * + * async_flip_planes bitmask is also used by selective + * fetch calculation to choose full frame update. */ new_crtc_state->async_flip_planes |= BIT(plane->id); } -- 2.47.3
