Propagate the error from intel_update_plane() up through intel_plane_restore() to the caller. This will be used for rollback purposes when setting properties fails. Cc: dri-devel@lists.freedesktop.org Signed-off-by:

The sprite planes (in fact all display planes starting from gen4) support 180 degree rotation. Add the relevant low level bits to the sprite code to make use of that feature. The upper layers are not yet plugged in. v2: HSW handles the rotated buffer offset automagically v3: BDW also handles the rotated buffer offset automagically Testcase: igt/kms_rotation_crc Cc: dri-devel@lists.freedesktop.org Signed-off-by:

Following the established idom, let's provide a macro to iterate through the encoders. spatch helps, once more, for the substitution: @@ iterator name list_for_each_entry; iterator name for_each_intel_encoder; struct intel_encoder * encoder; struct drm_device * dev; @@ -list_for_each_entry(encoder, &dev->mode_config.encoder_list, base.head) { +for_each_intel_encoder(dev, encoder) { ... } I also modified a few call sites by hand where a pointer to mode_config was directly used (to avoid overflowing 80 chars).

We used to carry a default HDMI value in entry 9, but this entry got removed for both HSW and BDW. Signed-off-by:

Damien Lespiau authored
We always write entries 0 to 8 from the DDI translation tables and then entry 9 for HDMI/DVI with the help of the VBT. We then don't need the failsafe HDMI entry in the DP/eDP/FDI tables. Signed-off-by:

Among the changes, the tables has only 10 entries instead of 12 on HSW and the index the the 800mV/0dB entry has changed. Signed-off-by:

Damien Lespiau authored
The knowledge about the HDMI/DVI DDI translation table was scattered around. - info->hdmi_level_shift was initialized with 6, the index of the 800 mV, 0dB translation - A check on the VBT value was done to ensure it wasn't overflowing the translation table (< 0xC) - The actual programming was done in intel_ddi.c As we need to change that knowledge for Broadwell, let's gather everything into one place.

With this bit enabled, HW changes the color when compressing frames for debug purposes. ALthough the simple way to enable a single bit is over intel_reg_write, this value is overwriten on next update_fbc so depending on the workload it is not possible to set this bit with intel-gpu-tools. So this patch introduces a persistent way to enable false color over debugfs. v2: Use DEFINE_SIMPLE_ATTRIBUTE as Daniel suggested v3: (Ville) only do false color for IVB+ since according to spec bit is MBZ before IVB. v4: We don't have FBC on valleyview nor on cherryview (Ben) v5: s/!HAS_PCH_SPLIT/!HAS_FBC (Ville) Cc: Ville Syrjälä <ville.syrjala@linux.intel.com> Reviewed-by:Ben Widawsky <ben@bwidawsk.net> Signed-off-by:

CHV was forgotten the intel_{dp,hdmi}_prepare() were introduced (or the chv patches were still in flight?). Call these when enabling the ports. Things tend to work much better when we actually write something to the port registers :) Signed-off-by: -

Looks like the Punit is supposed to support the 400MHz cdclk directly on chv, so we don't need the vlv tricks. FIXME: Punit doesn't seem ready for this yet on current hw Signed-off-by:

Since we started using intel_runtime_pm_disable_interrupts() at normal (non-runtime) suspend/resume, we had to remove a WARN from ironlake_disable_display_irq to avoid a case where we were doing the correct thing and the WARN was not really needed. The problem is that the WARN was useful in other cases, and its removal can hide some bugs that we would catch automatically. To be able to add back the WARN, we have to call intel_crtc_control() before interrupts are disabled, which is what this patch currently does. Also notice that Ville's patch from the Watermarks series "drm/i915: Leave interrupts enabled while disabling crtcs during suspend" also did a change that's equivalent to the one we're doing on this patch, with the exception that its original patch, when applied to the current tree, procduces a WARN.

CHV has two display PHYs so there are also two cmnlane power wells. Add the approriate code to power the wells up/down. Like on VLV we do the cmnreset assert/deassert and the DPLL refclock enabling at approriate times. This code actually works on my bsw. Signed-off-by:
