plane->fb is a legacy pointer that not always be up-to-date (or updated early enough). Make sure the watermark code uses plane->state->fb so that we're always doing our calculations based on the correct framebuffers. This patch was generated by Coccinelle with the following semantic patch: @@ struct drm_plane *P; @@ - P->fb + P->state->fb v2: Rebase Signed-off-by: Matt Roper <matthew.d.roper@xxxxxxxxx> --- drivers/gpu/drm/i915/intel_wm.c | 22 +++++++++++----------- 1 file changed, 11 insertions(+), 11 deletions(-) diff --git a/drivers/gpu/drm/i915/intel_wm.c b/drivers/gpu/drm/i915/intel_wm.c index 47a5175..e877e02 100644 --- a/drivers/gpu/drm/i915/intel_wm.c +++ b/drivers/gpu/drm/i915/intel_wm.c @@ -496,7 +496,7 @@ static void pineview_update_wm(struct drm_crtc *unused_crtc) crtc = single_enabled_crtc(dev); if (crtc) { const struct drm_display_mode *adjusted_mode; - int pixel_size = crtc->primary->fb->bits_per_pixel / 8; + int pixel_size = crtc->primary->state->fb->bits_per_pixel / 8; int clock; adjusted_mode = &to_intel_crtc(crtc)->config->base.adjusted_mode; @@ -572,7 +572,7 @@ static bool g4x_compute_wm0(struct drm_device *dev, clock = adjusted_mode->crtc_clock; htotal = adjusted_mode->crtc_htotal; hdisplay = to_intel_crtc(crtc)->config->pipe_src_w; - pixel_size = crtc->primary->fb->bits_per_pixel / 8; + pixel_size = crtc->primary->state->fb->bits_per_pixel / 8; /* Use the small buffer method to calculate plane watermark */ entries = ((clock * pixel_size / 1000) * display_latency_ns) / 1000; @@ -659,7 +659,7 @@ static bool g4x_compute_srwm(struct drm_device *dev, clock = adjusted_mode->crtc_clock; htotal = adjusted_mode->crtc_htotal; hdisplay = to_intel_crtc(crtc)->config->pipe_src_w; - pixel_size = crtc->primary->fb->bits_per_pixel / 8; + pixel_size = crtc->primary->state->fb->bits_per_pixel / 8; line_time_us = max(htotal * 1000 / clock, 1); line_count = (latency_ns / line_time_us + 1000) / 1000; @@ -742,7 +742,7 @@ static void vlv_update_drain_latency(struct drm_crtc *crtc) } /* Primary plane Drain Latency */ - pixel_size = crtc->primary->fb->bits_per_pixel / 8; /* BPP */ + pixel_size = crtc->primary->state->fb->bits_per_pixel / 8; /* BPP */ if (vlv_compute_drain_latency(crtc, pixel_size, &prec_mult, &drain_latency)) { plane_prec = (prec_mult == high_precision) ?
