* | | | drm/i915: Avoid keeping waitboost active for signaling threadsChris Wilson2017-06-281-3/+2
| |_|/ |/| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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 b29c19b64528 ("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: Michał Winiarski <michal.winiarski@intel.com> Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk> Cc: Michał Winiarski <michal.winiarski@intel.com> Reviewed-by: Michał Winiarski <michal.winiarski@intel.com> Link: http://patchwork.freedesktop.org/patch/msgid/20170628123548.9236-1-chris@chris-wilson.co.uk
* | | drm/i915: Add i830 "pipes power well"Ville Syrjälä2017-06-151-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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: Ville Syrjälä <ville.syrjala@linux.intel.com> Link: http://patchwork.freedesktop.org/patch/msgid/20170601143619.27840-5-ville.syrjala@linux.intel.com Acked-by: Maarten Lankhorst <maarten.lankhorst@linux.intel.com>

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.

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. For each enabled plane on the pipe { If plane scaling enabled { Horizontal down scale amount = Maximum[1, plane horizontal size / scaler horizontal window size] Vertical down scale amount = Maximum[1, plane vertical size / scaler vertical window size] Plane down scale amount = Horizontal down scale amount * Vertical down scale amount Plane Ratio = 1 / Plane down scale amount } Else { Plane Ratio = 1 } If plane source pixel format is 64 bits per pixel { Plane Ratio = Plane Ratio * 8/9 } } Pipe Ratio = Minimum Plane Ratio of all enabled planes on the pipe If pipe scaling is enabled { Horizontal down scale amount = Maximum[1, pipe horizontal source size / scaler horizontal window size] Vertical down scale amount = Maximum[1, pipe vertical source size / scaler vertical window size] Note: The progressive fetch - interlace display mode is equivalent to a 2.0 vertical down scale Pipe down scale amount = Horizontal down scale amount * Vertical down scale amount Pipe Ratio = Pipe Ratio / Pipe down scale amount } Pipe maximum pixel rate = CDCLK frequency * Pipe Ratio In this patch our calculation is based on pipe downscale amount (plane max downscale amount * pipe downscale amount) instead of Pipe Ratio. 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.

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.

| * | drm/i915: Two stage watermarks for g4xVille Syrjälä2017-05-101-0/+28
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

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 (233ce881dd91fb "drm/i915: Implement Link Rate fallback on Link training failure") which got reverted in this commit id (afc1ebf4562a14 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 (bb1d132935c2f8 "drm/i915/vbt: split out defaults that are set when there is no VBT) and (665788572c6410b "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: Tony Cheng <tony.cheng@amd.com> Acked-by: Harry 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: Manasi Navare <manasi.d.navare@intel.com> Reviewed-by: Jani Nikula <jani.nikula@intel.com> Signed-off-by: Jani Nikula <jani.nikula@intel.com> Link: http://patchwork.freedesktop.org/patch/msgid/16ca48b1e74c618929245e9a085b9e3483c3a16d.1491485983.git.jani.nikula@intel.com

There are three changes here that are rather difficult to split up: 1) Use the intel_dp->sink_rates array for all DP, not just eDP 1.4. We initialize it from DPCD on eDP 1.4 like before, but generate it based on DP_MAX_LINK_RATE on others. This reduces code complexity when we need to use the sink rates; they are all always in the sink_rates array. 2) Update the sink rate array whenever we read DPCD, and use the information from there. This increases code readability when we need the sink rates. 3) Disentangle fallback rate limiting from sink rates. In the code, the max rate is a dynamic property of the *link*, not of the *sink*. Do the limiting after intersecting the source and sink rates, which are static properties of the devices. This paves the way for follow-up refactoring that I've refrained from doing here to keep this change as simple as it possibly can. v2: introduce use_rate_select and handle non-confirming eDP (Ville) v3: don't clobber cached eDP rates on short pulse (Ville) Cc: Manasi Navare <manasi.d.navare@intel.com> Cc: Ville Syrjälä <ville.syrjala@linux.intel.com> Reviewed-by: Manasi Navare <manasi.d.navare@intel.com> Signed-off-by: Jani Nikula <jani.nikula@intel.com> Link: http://patchwork.freedesktop.org/patch/msgid/071bad76467f8ab2e73f3f61ad52d5a468004c71.1490712890.git.jani.nikula@intel.com

For example some HDMI modes might be rejected when a connector property forces the connector into DVI mode. Some implementations of detect() already lock all state, so we have to pass an acquire_ctx to them to prevent a deadlock. This means changing the function signature of detect() slightly, and passing the acquire_ctx for locking multiple crtc's. For the callbacks, it will always be non-zero. To allow callers not to worry about this, drm_helper_probe_detect_ctx is added which might handle -EDEADLK for you. Changes since v1: - Always set ctx parameter. Changes since v2: - Always take connection_mutex when probing.

HDMI 2.0 spec mendates scrambling for these higher clocks, for reduced RF footprint. This patch checks if the monitor supports scrambling, and if required, enables it during the modeset. V2: Addressed review comments from Ville: - Do not track scrambling status in DRM layer, track somewhere in driver like in intel_crtc_state. - Don't talk to monitor at such a low layer, set monitor scrambling in intel_enable_ddi() before enabling the port. V3: Addressed review comments from Jani - In comments, function names, use "sink" instead of "monitor", so that the implementation could be close to the language of HDMI spec. V4: Addressed review comment from Maarten - scrambling -> hdmi_scrambling - high_tmds_clock_ratio -> hdmi_high_tmds_clock_ratio V5: Addressed review comments from Ville and Ander - Do not modifiy the crtc_state after compute_config. Move all scrambling and tmds_clock_ratio calcutations to compute_config. - While setting scrambling for source/sink, do not check the conditions again, just go by the crtc_state flags.
