Modify drain latency computation to use it for any plane. Same function can be used for primary, cursor and sprite planes. v2: Adressed review comments by Imre and Ville. - Moved clock round up in separate patch - Added WARN check for clock and pixel size - Simplified bit masking - Use cursor_base instead of reg read v3: Changed to bitwise shorthand operator for plane_dl assignment.

If there are pending page flips when the fd gets closed those page flips may have events associated to them. When the page flip eventually completes it will queue the event to file_priv->event_list, but that may be too late and file_priv->event_list has already been cleaned up. Thus we leak a bit of kernel memory in the form of the event structure. To avoid such problems clear out such pending events from intel_crtc->unpin_work at ->preclose(). Any event that already made it to file_priv->event_list will get cleaned up by the drm_release_events() a bit later. We can ignore the file_priv->event_space accounting since file_priv is going away. This is already how drm core deals with pending vblank events, which are maintained by the drm core. What saves us from a total disaster (ie. dereferencing and alrady freed file_priv) is the fact that the fb descruction triggers a modeset and there we wait for pending flips. Signed-off-by:

sanitize_enable_ppgtt is the function that checks all the conditions, honoring a forced ppgtt status or doing auto-detect as necessary. Just make sure it returns the right value in all cases and use that in the macros instead of the confusing intel_enable_ppgtt() function. Signed-off-by:

Replace the semi-funky cmnlane assert/deassert macros with something a bit more conventional. Also protect the macro arguments properly (also for PHY_POWERGOOD()). Reviewed-by:

It looks like frobbing the cmnreset line on pne PHY disturbs the other PHY on chv. The result is a black screen. On HDMI it's just a flash of black, but DP usually falls over and can't get back up. As a workaround set up the power domains so that both common lane wells power up and down together. I also tried leaving the cmnreset deasserted even the if the power well goes down but that didn't seem acceptable to the PHY. Reviewed-by:

CHV has a third pipe so we need to compute the watermarks for its planes. Add cherryview_update_wm() to do just that. v2: Rebase on top of Imre's cxsr changes v3: Pass crtc to vlv_update_drain_latency() Reviewed-by:

Instead of looping through all CRTCs, update DDL for current CRTC for which watermark is being updated. CHV is confirmed to have precision of 32/64 which is same as VLV. Reviewed-by:

Ville Syrjälä authored
The VLV/CHV DDL registers are uniform, and neatly enough the register offsets are sane so we can easily unify them to a single set of defines and just pass the pipe as the parameter to compute the register offset. Note that we now fill out the drain latency for pipe C on CHV which we didn't do before. The rest of the pipe C watermarks are still untouched but that will be remedied later by adding a proper cherryview_update_wm() function. v2: Add a note about CHV pipe C changes (Paulo) Reviewed-by:

Ville Syrjälä authored
Add defines for all the watermark registers on modernish gmch platforms. VLV has increased the number of bits available for certain watermaks so expand the masks appropriately. Also vlv and chv have added some extra FW registers. Not sure what happened on chv because a new register called FW9 is now at the offset where FW7 was on vlv, while FW7 and FW8 (another new register) have been moved off somewhere else. Oh well, well just need two defines for FW7 then. v2: Fix DSPHOWM1 offset (Paulo) Reviewed-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).

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:

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.
