The first is in the MIPI config block, but that apparenly usually (maybe always?) indicates 0 degrees despite the actual panel orientation. The second way to indicate this is in the general features block, which can just indicate whether 180 degress rotation is used. The third might be a separate rotation data block, but that is not at all documented so who knows what it may contain. Let's try the first two. We first try the DSI specicic VBT information, and it it doesn't look trustworthy (ie. indicates 0 degrees) we fall back to the 180 degree thing. Just to avoid too many changes in one go we shall also keep the hardware readout path for now. If this works for more than just my VLV FFRD the question becomes how many of the panel orientation quirks are now redundant? v2: Move the code into intel_dsi.c (Jani) Cc: Hans de Goede Reviewed-by: Jani Nikula Signed-off-by: Ville Syrjälä Link: https://patchwork.freedesktop.org/patch/msgid/20181022142015.4026-1-ville.syrjala@linux.intel.com Tested-by: Hans de Goede --- drivers/gpu/drm/i915/intel_bios.c | 31 +++++++++++++++++++++++++++++++ 1 file changed, 31 insertions(+) (limited to 'drivers/gpu/drm/i915/intel_bios.c') diff --git a/drivers/gpu/drm/i915/intel_bios.c b/drivers/gpu/drm/i915/intel_bios.c index 0ad2304457ab..bd7b2da71419 100644 --- a/drivers/gpu/drm/i915/intel_bios.c +++ b/drivers/gpu/drm/i915/intel_bios.c @@ -420,6 +420,13 @@ parse_general_features(struct drm_i915_private *dev_priv, intel_bios_ssc_frequency(dev_priv, general->ssc_freq); dev_priv->vbt.display_clock_mode = general->display_clock_mode; dev_priv->vbt.fdi_rx_polarity_inverted = general->fdi_rx_polarity_inverted; + if (bdb->version >= 181) { + dev_priv->vbt.orientation = general->rotate_180 ? + DRM_MODE_PANEL_ORIENTATION_BOTTOM_UP : + DRM_MODE_PANEL_ORIENTATION_NORMAL; + } else { + dev_priv->vbt.orientation = DRM_MODE_PANEL_ORIENTATION_UNKNOWN; + } DRM_DEBUG_KMS("BDB_GENERAL_FEATURES int_tv_support %d int_crt_support %d lvds_use_ssc %d lvds_ssc_freq %d display_clock_mode %d fdi_rx_polarity_inverted %d\n", dev_priv->vbt.int_tv_support, dev_priv->vbt.int_crt_support, @@ -852,6 +859,30 @@ parse_mipi_config(struct drm_i915_private *dev_priv, parse_dsi_backlight_ports(dev_priv, bdb->version, port); + /* FIXME is the 90 vs. 270 correct? */ + switch (config->rotation) { + case ENABLE_ROTATION_0: + /* + * Most (all?)
