The enable/disable/etc. encoder hooks aren't supposed to alter the state(s), so pass them as const. Unfortunately C lacks any kind of deep const thingy, so this can't catch all abuses.

Some fixed resolution panels actually support more than one mode, with the only thing different being the refresh rate.

The driver stores lut values from the fbdev interface, and is able to give them back, but does not appear to do anything with these lut values. The generic fb helpers have replaced this function, and may even have made the driver work for the C8 mode from the fbdev interface. But that is untested.

This patch checks encoder level support for YCBCR420 outputs. The logic goes as simple as this: If the input mode is YCBCR420-only mode: prepare HDMI for YCBCR420 output, else continue with RGB output mode. It checks if the mode is YCBCR420 and source can support this output then it marks the ycbcr_420 output indicator into crtc state, for further staging in driver.

The pattern of a power well backing a set of pipe IRQ or VGA functionality applies to all HSW+ platforms. Using power well attributes instead of platform checks to decide whether to init/reset pipe IRQs and VGA correspondingly is cleaner and it allows us to unify the HSW/BDW and GEN9+ power well code in follow-up patches. Also use u8 for pipe_mask in related helpers to match the type in the power well struct. v2: - Use u8 instead of u32 for irq_pipe_mask.

First thing we need to do is unregister the fbdev instance, but we can't just go ahead and kfree it. That must wait until the hotplug and polling work are stopped, since they can race with the with the teardown. That means we need to split up the fbdev teardown into the unregister part and the cleanup part. I originally suspected that this was broken in one of the unload shuffles, but on closer inspection the oldest sequence I've dug out also gets this wrong. Just not quite so badly. I've run drv_module_reload a few hundred times and it's rock solid compared to insta-death beforehand.

Once a client has requested a waitboost, we keep that waitboost active until all clients are no longer waiting. This is because we don't distinguish which waiter deserves the boost. However, with the advent of fence signaling, the signaler threads appear as waiters to the RPS interrupt handler. So instead of using a single boolean to track when to keep the waitboost active, use a counter of all outstanding waitboosted requests. At this point, I have removed all vestiges of the rate limiting on clients. Whilst this means that compositors should remain more fluid, it also means that boosts are more prevalent. See commit b29c19b6 ("drm/i915: Boost RPS frequency for CPU stalls") for a longer discussion on the pros and cons of both approaches. A drawback of this implementation is that it requires constant request submission to keep the waitboost trimmed (as it is now cancelled when the request is completed). This will be fine for a busy system, but near idle the boosts may be kept for longer than desired (effectively tens of vblanks worstcase) and there is a reliance on rc6 instead. v2: Remove defunct rps.client_lock Reported-by: NMichał Winiarski <michal.winiarski@intel.com> Signed-off-by: NChris Wilson <chris@chris-wilson.co.uk> Cc: Michał Winiarski <michal.winiarski@intel.com> Reviewed-by: NMichał Winiarski <michal.winiarski@intel.com> Link: http://patchwork.freedesktop.org/patch/msgid/20170628123548.9236-1-chris@chris-wilson.co.uk

830 more or less requires both pipes and DPLLs to remain on as long as either pipe is needed. However, when neither pipe is actually needed, we can save a bit of power by turning everything off. To do that we add a new "power well" that turns both pipes and DPLLs on and off in the right order. Seems to save ~50mW on my Fujitsu-Siemens Lifebook S6010. This also avoids having to abuse the load detection to force pipe A on at init time. That was never very robust, and it only worked for one pipe, whereas 830 really needs both pipes enabled. As a bonus the 830 pipe quirk is now a bit more isolated from the rest of the mode setting infrastructure, which should mean that it's much less likely someone will accidentally break it in the future. The extra cost is of course slight code duplication, but that seems like a worthwile tradeoff here. v2; s/BIT/BIT_ULL/ Signed-off-by: NVille Syrjälä <ville.syrjala@linux.intel.com> Link: http://patchwork.freedesktop.org/patch/msgid/20170601143619.27840-5-ville.syrjala@linux.intel.comAcked-by: NMaarten Lankhorst <maarten.lankhorst@linux.intel.com>

Pass crtc_state to the enable callback, and connector_state to all callbacks. This will eliminate the need to guess for the correct pipe in these callbacks. The crtc state is required for pch_enable_backlight to obtain the correct cpu_transcoder. intel_dp_aux_backlight's setup function is called before hw readout, so crtc_state and connector_state->best_encoder are NULL in the enable() and set() callbacks.

A display resolution is only supported if it meets all the restrictions below for Maximum Pipe Pixel Rate. The display resolution must fit within the maximum pixel rate output from the pipe. Make sure that the display pipe is able to feed pixels at a rate required to support the desired resolution.

So, max supported crtc clock with given scaling = CDCLK / pipe downscale. Flip will fail if, current crtc clock > max supported crct clock with given scaling.

SDVO was the last connector that's still using the legacy paths for properties, and this is with a reason! This connector implements a lot of properties dynamically, and some of them shared with the digital connector state, so sdvo_connector_state subclasses intel_digital_connector_state. set_property had a lot of validation, but this is handled in the drm core, so most of the validation can die off. The properties are written right before enabling the connector, since there is no good way to update the properties without crtc.

intel_hdmi supports 3 properties, force_audio, broadcast rgb and scaling mode. The last one is only created for eDP, so the is_eDP in set_property is not required. panel fitting and broadcast rgb are straightforward and only requires changing compute_config. force_audio is also used to force DVI mode, which means changes to compute_config and mode_valid. mode_valid is called with connection_mutex held, so it can safely dereference connector->state.

Some atomic properties are common between the various kinds of connectors, for example a lot of them use panel fitting mode. It makes sense to put a lot of it in a common place, so each connector can use it while they're being converted. Implement the properties required for the connectors: - scaling mode property - force audio property - broadcast rgb - aspect ratio While at it, make clear that intel_digital_connector_atomic_get_property is a hack that has to be removed when all connector properties are converted to atomic. Changes since v1: - Scaling mode and aspect ratio are partly handled in core now. Changes since v2: - Split out the scaling mode / aspect ratio changes to a preparation patch. - Use mode_changed for panel fitter, changes to this property are checked by fastset. - Allowed_scaling_modes is removed, handled through core now.

Move cursor_base, cursor_cntl, and cursor_size from intel_crtc into intel_plane so that we don't need the crtc for cursor stuff so much. Also entirely nuke cursor_addr which IMO doesn't provide any benefit since it's not actually used by the cursor code itself. I'm not 100% sure what the SKL+ DDB is code is after by looking at cursor_addr so I just make it do its checks unconditionally. If that's not correct then we should likely replace it with somehting like plane_state->visible.

Implement proper two stage watermark programming for g4x. As with other pre-SKL platforms, the watermark registers aren't double buffered on g4x. Hence we must sequence the watermark update carefully around plane updates. The code is quite heavily modelled on the VLV/CHV code, with some fairly significant differences due to the different hardware architecture: * g4x doesn't use inverted watermark values * CxSR actually affects the watermarks since it controls memory self refresh in addition to the max FIFO mode * A further HPLL SR mode is possible with higher memory wakeup latency * g4x has FBC2 and so it also has FBC watermarks * max FIFO mode for primary plane only (cursor is allowed, sprite is not) * g4x has no manual FIFO repartitioning * some TLB miss related workarounds are needed for the watermarks Actually the hardware is quite similar to ILK+ in many ways. The most visible differences are in the actual watermakr register layout. ILK revamped that part quite heavily whereas g4x is still using the layout inherited from earlier platforms. Note that we didn't previously enable the HPLL SR on g4x. So in order to not introduce too many functional changes in this patch I've not actually enabled it here either, even though the code is now fully ready for it. We'll enable it separately later on.

If link training at a link rate optimal for a particular mode fails during modeset's atomic commit phase, then we let the modeset complete and then retry. We save the link rate value at which link training failed, update the link status property to "BAD" and use a lower link rate to prune the modes. It will redo the modeset on the current mode at lower link rate or if the current mode gets pruned due to lower link constraints then, it will send a hotplug uevent for userspace to handle it. This is also required to pass DP CTS tests 4.3.1.3, 4.3.1.4, 4.3.1.6. This patch is a resend of the original commit id (233ce881 "drm/i915: Implement Link Rate fallback on Link training failure") which got reverted in this commit id (afc1ebf4 Revert "drm/i915: Implement Link Rate fallback on Link training failure") due to CI failures. After investigating the CI failures it was found that these were essentially the failures which were always there but hidden because they used to be DRM_DEBUG_KMS messages for link failures so never got caught by CI. But now this patch actually throws DRM_ERROR if the link training fails at RBR and 1 lane. So it caught these link train failures. There were two failures: 1. On SKL 6700k this was because the machine in CI lab is a SKL desktop without eDP on Port A. But our VBT initialization code in the driver writes VBT defaults in a way that it always sets DP flag on Port A and this does not get cleared after parsing the VBT outputs. This has been fixed in commit id (bb1d1329 "drm/i915/vbt: split out defaults that are set when there is no VBT) and (66578857 "drm/i915/vbt: don't propagate errors from intel_bios_init()) 2. On ILK-650 desktop - This was happening because of a bad monitor desktop combination. I switched the monitor in the CI lab and that helped get rid of the link failures on ILK system. v10: * Rebase on drm-tip and resend after revert v9: * Use the trimmed max values of link rate/lane count based on link train fallback (Daniel Vetter) v8: * Set link_status to BAD first and then call mode_valid (Jani Nikula) v7: Remove the redundant variable in previous patch itself v6: * Obtain link rate index from fallback_link_rate using the helper intel_dp_link_rate_index (Jani Nikula) * Include fallback within intel_dp_start_link_train (Jani Nikula) v5: * Move set link status to drm core (Daniel Vetter, Jani Nikula) v4: * Add fallback support for non DDI platforms too * Set connector->link status inside set_link_status function (Jani Nikula) v3: * Set link status property to BAd unconditionally (Jani Nikula) * Dont use two separate variables link_train_failed and link_status to indicate same thing (Jani Nikula) v2: * Squashed a few patches (Jani Nikula) Acked-by: NTony Cheng <tony.cheng@amd.com> Acked-by: NHarry Wentland <Harry.wentland@amd.com> Cc: Jani Nikula <jani.nikula@linux.intel.com> Cc: Daniel Vetter <daniel.vetter@intel.com> Cc: Ville Syrjala <ville.syrjala@linux.intel.com> Signed-off-by: NManasi Navare <manasi.d.navare@intel.com> Reviewed-by: NJani Nikula <jani.nikula@intel.com> Signed-off-by: NJani Nikula <jani.nikula@intel.com> Link: http://patchwork.freedesktop.org/patch/msgid/16ca48b1e74c618929245e9a085b9e3483c3a16d.1491485983.git.jani.nikula@intel.com

Now that source rates are static and sink rates are updated whenever DPCD is updated, we can do and cache the intersection of them whenever sink rates are updated. This reduces code complexity, as we don't have to keep calling the functions to intersect. We also get rid of several common rates arrays on stack.
