From afbd8a722bd64e0020a3b2f8ac2c42e02dc8f596 Mon Sep 17 00:00:00 2001 From: =?utf8?q?Ville=20Syrj=C3=A4l=C3=A4?= Date: Tue, 27 Nov 2018 18:37:42 +0200 Subject: [PATCH] drm/i915: Introduce crtc_state->update_planes bitmask MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit Keep track which planes need updating during the commit. For now we set the bit for any plane that was or will be visible (including icl+ nv12 slave planes). In the future I'll have need to update invisible planes as well, for skl plane ddbs and for pre-skl pipe gamma/csc control (which lives in the primary plane control register). v2: Pimp the commit message to mention icl+ nv12 slave planes (Matt) Reviewed-by: Rodrigo Vivi Reviewed-by: Maarten Lankhorst Reviewed-by: Matt Roper Signed-off-by: Ville Syrjälä Link: https://patchwork.freedesktop.org/patch/msgid/20181127163742.30215-1-ville.syrjala@linux.intel.com --- drivers/gpu/drm/i915/intel_atomic.c | 1 + drivers/gpu/drm/i915/intel_atomic_plane.c | 8 ++++---- drivers/gpu/drm/i915/intel_display.c | 5 ++++- drivers/gpu/drm/i915/intel_drv.h | 3 +++ 4 files changed, 12 insertions(+), 5 deletions(-) diff --git a/drivers/gpu/drm/i915/intel_atomic.c b/drivers/gpu/drm/i915/intel_atomic.c index a5a2c8fe58a7..8cb02f28d30c 100644 --- a/drivers/gpu/drm/i915/intel_atomic.c +++ b/drivers/gpu/drm/i915/intel_atomic.c @@ -184,6 +184,7 @@ intel_crtc_duplicate_state(struct drm_crtc *crtc) crtc_state->fifo_changed = false; crtc_state->wm.need_postvbl_update = false; crtc_state->fb_bits = 0; + crtc_state->update_planes = 0; return &crtc_state->base; } diff --git a/drivers/gpu/drm/i915/intel_atomic_plane.c b/drivers/gpu/drm/i915/intel_atomic_plane.c index 905f8ef3ba4f..026a11511941 100644 --- a/drivers/gpu/drm/i915/intel_atomic_plane.c +++ b/drivers/gpu/drm/i915/intel_atomic_plane.c @@ -139,6 +139,9 @@ int intel_plane_atomic_check_with_state(const struct intel_crtc_state *old_crtc_ if (state->visible && state->fb->format->format == DRM_FORMAT_NV12) crtc_state->nv12_planes |= BIT(intel_plane->id); + if (state->visible || old_plane_state->base.visible) + crtc_state->update_planes |= BIT(intel_plane->id); + return intel_plane_atomic_calc_changes(old_crtc_state, &crtc_state->base, old_plane_state, @@ -173,14 +176,11 @@ void intel_update_planes_on_crtc(struct intel_atomic_state *old_state, struct intel_crtc_state *old_crtc_state, struct intel_crtc_state *new_crtc_state) { + u32 update_mask = new_crtc_state->update_planes; struct intel_plane_state *new_plane_state; struct intel_plane *plane; - u32 update_mask; int i; - update_mask = old_crtc_state->active_planes; - update_mask |= new_crtc_state->active_planes; - for_each_new_intel_plane_in_state(old_state, plane, new_plane_state, i) { if (crtc->pipe != plane->pipe || !(update_mask & BIT(plane->id))) diff --git a/drivers/gpu/drm/i915/intel_display.c b/drivers/gpu/drm/i915/intel_display.c index 3516b3d04787..4469b4511c92 100644 --- a/drivers/gpu/drm/i915/intel_display.c +++ b/drivers/gpu/drm/i915/intel_display.c @@ -10839,8 +10839,10 @@ static int icl_check_nv12_planes(struct intel_crtc_state *crtc_state) continue; plane_state->linked_plane = NULL; - if (plane_state->slave && !plane_state->base.visible) + if (plane_state->slave && !plane_state->base.visible) { crtc_state->active_planes &= ~BIT(plane->id); + crtc_state->update_planes |= BIT(plane->id); + } plane_state->slave = false; } @@ -10881,6 +10883,7 @@ static int icl_check_nv12_planes(struct intel_crtc_state *crtc_state) linked_state->slave = true; linked_state->linked_plane = plane; crtc_state->active_planes |= BIT(linked->id); + crtc_state->update_planes |= BIT(linked->id); DRM_DEBUG_KMS("Using %s as Y plane for %s\n", linked->base.name, plane->base.name); } diff --git a/drivers/gpu/drm/i915/intel_drv.h b/drivers/gpu/drm/i915/intel_drv.h index a62d77b76291..1f29061cefa1 100644 --- a/drivers/gpu/drm/i915/intel_drv.h +++ b/drivers/gpu/drm/i915/intel_drv.h @@ -926,6 +926,9 @@ struct intel_crtc_state { u8 active_planes; u8 nv12_planes; + /* bitmask of planes that will be updated during the commit */ + u8 update_planes; + /* HDMI scrambling status */ bool hdmi_scrambling; -- 2.30.2
