From da9976206c15178eeae1b4445c9266125bf35b0a Mon Sep 17 00:00:00 2001 From: Alex Deucher Date: Wed, 9 Jul 2014 13:21:59 -0400 Subject: [PATCH] drm/radeon: enable display scaling on all connectors (v2) This enables the display scaler on all connectors for r5xx and newer asics. Previously we only enabled the scaler for fixed mode displays (eDP or LVDS) since they have to use the scaler to support non-native modes. Most other displays are multi-sync or have a built in scaler to support non-native modes. The default scaling mode for non-fixed displays is none which will use the scaler in the monitor. Note that we do not populate any fake modes like we do for fixed displays so it will only use the modes in the edid. For other modes, you'll need to populate them manually. bug: https://bugs.freedesktop.org/show_bug.cgi?id=80868 v2: properly handle scaling with no modes defined Signed-off-by: Alex Deucher --- drivers/gpu/drm/radeon/atombios_encoders.c | 10 +- drivers/gpu/drm/radeon/radeon_connectors.c | 106 +++++++++++++++++---- 2 files changed, 95 insertions(+), 21 deletions(-) diff --git a/drivers/gpu/drm/radeon/atombios_encoders.c b/drivers/gpu/drm/radeon/atombios_encoders.c index 7d68203a3737..34fe641c3b51 100644 --- a/drivers/gpu/drm/radeon/atombios_encoders.c +++ b/drivers/gpu/drm/radeon/atombios_encoders.c @@ -331,12 +331,10 @@ static bool radeon_atom_mode_fixup(struct drm_encoder *encoder, && (mode->crtc_vsync_start < (mode->crtc_vdisplay + 2))) adjusted_mode->crtc_vsync_start = adjusted_mode->crtc_vdisplay + 2;
