From 8c3f6bb970413c6a537736f409a1bc9d8abd671c Mon Sep 17 00:00:00 2001 From: Ben Skeggs Date: Mon, 18 Apr 2011 09:57:48 +1000 Subject: [PATCH] drm/nouveau: recognise DCB connector type 0x41 as LVDS After looking at a number of different logs, it appears 0x41 likely indicates the presense of an LVDS panel following the SPWG spec (http://www.spwg.org/) Signed-off-by: Ben Skeggs --- drivers/gpu/drm/nouveau/nouveau_bios.c | 1 + drivers/gpu/drm/nouveau/nouveau_bios.h | 1 + drivers/gpu/drm/nouveau/nouveau_connector.c | 8 +++++--- 3 files changed, 7 insertions(+), 3 deletions(-) diff --git a/drivers/gpu/drm/nouveau/nouveau_bios.c b/drivers/gpu/drm/nouveau/nouveau_bios.c index 8486dc6ee16c..729d5fd7c88d 100644 --- a/drivers/gpu/drm/nouveau/nouveau_bios.c +++ b/drivers/gpu/drm/nouveau/nouveau_bios.c @@ -6031,6 +6031,7 @@ parse_dcb_connector_table(struct nvbios *bios) case DCB_CONNECTOR_DVI_I: case DCB_CONNECTOR_DVI_D: case DCB_CONNECTOR_LVDS: + case DCB_CONNECTOR_LVDS_SPWG: case DCB_CONNECTOR_DP: case DCB_CONNECTOR_eDP: case DCB_CONNECTOR_HDMI_0: diff --git a/drivers/gpu/drm/nouveau/nouveau_bios.h b/drivers/gpu/drm/nouveau/nouveau_bios.h index 8a54fa7edf5c..050c314119df 100644 --- a/drivers/gpu/drm/nouveau/nouveau_bios.h +++ b/drivers/gpu/drm/nouveau/nouveau_bios.h @@ -82,6 +82,7 @@ enum dcb_connector_type { DCB_CONNECTOR_DVI_I = 0x30, DCB_CONNECTOR_DVI_D = 0x31, DCB_CONNECTOR_LVDS = 0x40, + DCB_CONNECTOR_LVDS_SPWG = 0x41, DCB_CONNECTOR_DP = 0x46, DCB_CONNECTOR_eDP = 0x47, DCB_CONNECTOR_HDMI_0 = 0x60, diff --git a/drivers/gpu/drm/nouveau/nouveau_connector.c b/drivers/gpu/drm/nouveau/nouveau_connector.c index 7ae151109a66..1595d0b6e815 100644 --- a/drivers/gpu/drm/nouveau/nouveau_connector.c +++ b/drivers/gpu/drm/nouveau/nouveau_connector.c @@ -442,7 +442,7 @@ nouveau_connector_set_property(struct drm_connector *connector, } /* LVDS always needs gpu scaling */ - if (nv_connector->dcb->type == DCB_CONNECTOR_LVDS && + if (connector->connector_type == DRM_MODE_CONNECTOR_LVDS && value == DRM_MODE_SCALE_NONE) return -EINVAL; @@ -650,6 +650,7 @@ nouveau_connector_get_modes(struct drm_connector *connector) ret = get_slave_funcs(encoder)->get_modes(encoder, connector); if (nv_connector->dcb->type == DCB_CONNECTOR_LVDS || + nv_connector->dcb->type == DCB_CONNECTOR_LVDS_SPWG || nv_connector->dcb->type == DCB_CONNECTOR_eDP) ret += nouveau_connector_scaler_modes_add(connector); @@ -810,6 +811,7 @@ nouveau_connector_create(struct drm_device *dev, int index) type = DRM_MODE_CONNECTOR_HDMIA; break; case DCB_CONNECTOR_LVDS: + case DCB_CONNECTOR_LVDS_SPWG: type = DRM_MODE_CONNECTOR_LVDS; funcs = &nouveau_connector_funcs_lvds; break; @@ -838,7 +840,7 @@ nouveau_connector_create(struct drm_device *dev, int index) drm_connector_helper_add(connector, &nouveau_connector_helper_funcs); /* Check if we need dithering enabled */ - if (dcb->type == DCB_CONNECTOR_LVDS) { + if (connector->connector_type == DRM_MODE_CONNECTOR_LVDS) { bool dummy, is_24bit = false; ret = nouveau_bios_parse_lvds_table(dev, 0, &dummy, &is_24bit); @@ -883,7 +885,7 @@ nouveau_connector_create(struct drm_device *dev, int index) nv_connector->use_dithering ?
