I noticed this issue recently and I'm glad that you posted solution. Code is fine, just few nitpicks and I think it would be better to split it in two commits, one which adds callback and another which implements that callback in sun8i-mixer. DE1 also needs this fix, but it can be posted later. > > Signed-off-by: Roman Stratiienko > --- > drivers/gpu/drm/sun4i/sun4i_crtc.c | 4 +++ > drivers/gpu/drm/sun4i/sun8i_mixer.c | 35 ++++++++++++++++++++++++++ > drivers/gpu/drm/sun4i/sun8i_ui_layer.c | 30 ---------------------- > drivers/gpu/drm/sun4i/sunxi_engine.h | 8 ++++++ > 4 files changed, 47 insertions(+), 30 deletions(-) > > diff --git a/drivers/gpu/drm/sun4i/sun4i_crtc.c > b/drivers/gpu/drm/sun4i/sun4i_crtc.c index 3a153648b369..156ea8f19d7d > 100644 > --- a/drivers/gpu/drm/sun4i/sun4i_crtc.c > +++ b/drivers/gpu/drm/sun4i/sun4i_crtc.c > @@ -139,8 +139,12 @@ static void sun4i_crtc_mode_set_nofb(struct drm_crtc > *crtc) struct drm_display_mode *mode = &crtc->state->adjusted_mode; > struct drm_encoder *encoder = sun4i_crtc_get_encoder(crtc); > struct sun4i_crtc *scrtc = drm_crtc_to_sun4i_crtc(crtc); > + struct sunxi_engine *engine = scrtc->engine; > > sun4i_tcon_mode_set(scrtc->tcon, encoder, mode); > + > + if (engine->ops->mode_set) > + engine->ops->mode_set(engine, mode); > } > > static const struct drm_crtc_helper_funcs sun4i_crtc_helper_funcs = { > diff --git a/drivers/gpu/drm/sun4i/sun8i_mixer.c > b/drivers/gpu/drm/sun4i/sun8i_mixer.c index eea4813602b7..bb9a665fd053 > 100644 > --- a/drivers/gpu/drm/sun4i/sun8i_mixer.c > +++ b/drivers/gpu/drm/sun4i/sun8i_mixer.c > @@ -257,6 +257,40 @@ const struct de2_fmt_info *sun8i_mixer_format_info(u32 > format) return NULL; > } > > +static void sun8i_mode_set(struct sunxi_engine *engine, > + struct drm_display_mode *mode) > +{ > + u32 dst_w = mode->crtc_hdisplay; > + u32 dst_h = mode->crtc_vdisplay; > + u32 outsize = SUN8I_MIXER_SIZE(dst_w, dst_h); > + bool interlaced = false; > + u32 val; > + struct sun8i_mixer *mixer = engine_to_sun8i_mixer(engine); > + u32 bld_base = sun8i_blender_base(mixer); > + > + DRM_DEBUG_DRIVER("Mode change, updating global size W: %u H: %u\n", > + dst_w, dst_h); We should start using newly introduced helpers for DRM debug output, in this case drm_dbg(), which replace those in in all caps. > + regmap_write(mixer->engine.regs, > + SUN8I_MIXER_GLOBAL_SIZE, > + outsize); > + regmap_write(mixer->engine.regs, > + SUN8I_MIXER_BLEND_OUTSIZE(bld_base), outsize); > + > + interlaced = mode->flags & DRM_MODE_FLAG_INTERLACE; > + > + if (interlaced) > + val = SUN8I_MIXER_BLEND_OUTCTL_INTERLACED; > + else > + val = 0; > + > + regmap_update_bits(mixer->engine.regs, > + SUN8I_MIXER_BLEND_OUTCTL(bld_base), > + SUN8I_MIXER_BLEND_OUTCTL_INTERLACED, > + val); > + DRM_DEBUG_DRIVER("Switching display mixer interlaced mode %s\n", > + interlaced ?
