From: Ville Syrjälä <[email protected]> All the bits in the VBT child device type have some speciifc meaning, so looking for an exact match isn't always the right thing. On some VLVs for example the device type for eDP panels is 0x1806.
If we mask out the bits that could concievably change between different eDP panels, we are left with the set of bits that should still tell us if the port is eDP or not. v2: Use the named bits for VBT child device type Bugzilla: https://bugs.freedesktop.org/show_bug.cgi?id=71051 Tested-by: Robert Hooker <[email protected]> Signed-off-by: Ville Syrjälä <[email protected]> --- drivers/gpu/drm/i915/intel_bios.h | 18 ++++++++++++++++++ drivers/gpu/drm/i915/intel_dp.c | 3 ++- 2 files changed, 20 insertions(+), 1 deletion(-) diff --git a/drivers/gpu/drm/i915/intel_bios.h b/drivers/gpu/drm/i915/intel_bios.h index f439c14..f580a2b 100644 --- a/drivers/gpu/drm/i915/intel_bios.h +++ b/drivers/gpu/drm/i915/intel_bios.h @@ -654,6 +654,24 @@ int intel_parse_bios(struct drm_device *dev); #define DEVICE_TYPE_DIGITAL_OUTPUT (1 << 1) #define DEVICE_TYPE_ANALOG_OUTPUT (1 << 0) +/* + * Bits we care about when checking for DEVICE_TYPE_eDP + * Depending on the system, the other bits may or may not + * be set for eDP outputs. + */ +#define DEVICE_TYPE_eDP_BITS \ + (DEVICE_TYPE_INTERNAL_CONNECTOR | \ + DEVICE_TYPE_NOT_HDMI_OUTPUT | \ + DEVICE_TYPE_MIPI_OUTPUT | \ + DEVICE_TYPE_COMPOSITE_OUTPUT | \ + DEVICE_TYPE_DUAL_CHANNEL | \ + DEVICE_TYPE_LVDS_SINGALING | \ + DEVICE_TYPE_TMDS_DVI_SIGNALING | \ + DEVICE_TYPE_VIDEO_SIGNALING | \ + DEVICE_TYPE_DISPLAYPORT_OUTPUT | \ + DEVICE_TYPE_DIGITAL_OUTPUT | \ + DEVICE_TYPE_ANALOG_OUTPUT) + /* define the DVO port for HDMI output type */ #define DVO_B 1 #define DVO_C 2 diff --git a/drivers/gpu/drm/i915/intel_dp.c b/drivers/gpu/drm/i915/intel_dp.c index f25a49e..ee3f573 100644 --- a/drivers/gpu/drm/i915/intel_dp.c +++ b/drivers/gpu/drm/i915/intel_dp.c @@ -3284,7 +3284,8 @@ bool intel_dp_is_edp(struct drm_device *dev, enum port port) p_child = dev_priv->vbt.child_dev + i; if (p_child->common.dvo_port == port_mapping[port] && - p_child->common.device_type == DEVICE_TYPE_eDP) + (p_child->common.device_type & DEVICE_TYPE_eDP_BITS) == + (DEVICE_TYPE_eDP & DEVICE_TYPE_eDP_BITS)) return true; } return false; -- 1.8.1.5 _______________________________________________ Intel-gfx mailing list [email protected] http://lists.freedesktop.org/mailman/listinfo/intel-gfx
