* drm/i915: Remove mostly duplicated video DIP handling from PSR codeVille Syrjälä2017-10-171-1/+1
| | | | | | | | | | | | | | | | Now that the infoframe hooks are part of the intel_dig_port, we can use the normal .write_infoframe() hook to update the VSC SDP. We do need to deal with the size difference between the VSC DIP and the others though. Another minor snag is that the compiler will complain to use if we keep using enum hdmi_infoframe_type type and passing in the DP define instead, so et's just change to unsigned int all over for the inforframe type. v2: Rebase due to other PSR changes Reviewed-by: Rodrigo Vivi <rodrigo.vivi@intel.com> Signed-off-by: Ville Syrjälä <ville.syrjala@linux.intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20171013194051.19286-1-ville.syrjala@linux.intel.com
* drm/i915: Start tracking PSR state in crtc stateVille Syrjälä2017-10-121-0/+5
| | | | | | | | | | | | | | | | | | | Add the minimal amount of PSR tracking into the crtc state. This allows precomputing the possibility of using PSR correctly, and it means we can safely call the psr enable/disable functions for any DP endcoder. As a nice bonus we get rid of some more crtc->config usage, which we want to kill off eventually. v2: Fix 'goto unlock' fail in intel_psr_enable() (Jani) Check intel_dp_is_edp() in is_edp_psr() (Jani) Cc: Rodrigo Vivi <rodrigo.vivi@intel.com> Cc: Jani Nikula <jani.nikula@intel.com> Signed-off-by: Ville Syrjälä <ville.syrjala@linux.intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20171012130201.21318-1-ville.syrjala@linux.intel.com Reviewed-by: Jani Nikula <jani.nikula@intel.com> Acked-by: Rodrigo Vivi <rodrigo.vivi@intel.com>
* drm/i915: Reuse normal state readout for LVDS/DVO fixed modeVille Syrjälä2017-10-111-2/+3
| | | | | | | | | | | | | | Reuse the normal state readout code to get the fixed mode for LVDS/DVO encoders. This removes some partially duplicated state readout code from LVDS/DVO encoders. The duplicated code wasn't actually even populating the negative h/vsync flags, leading to possible state checker complaints. The normal readout code populates that stuff fully.

* drm/i915: Enable scanline read based on frame timestampsUma Shankar2017-09-261-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | For certain platforms on certain encoders, timings are driven from port instead of pipe. Thus, we can't rely on pipe scanline registers to get the timing information. Some cases scanline register read will not be functional. This is causing vblank evasion logic to fail since it relies on scanline, causing atomic update failure warnings. This patch uses pipe framestamp and current timestamp registers to calculate scanline. This is an indirect way to get the scanline. It helps resolve atomic update failure for gen9 dsi platforms. v2: Addressed Ville and Daniel's review comments. Updated the register MACROs, handled race condition for register reads, extracted timings from the hwmode. Removed the dependency on crtc->config to get the encoder type. v3: Made get scanline function generic v4: Addressed Ville's review comments. Added a flag to decide timestamp based scanline reporting. Changed 64bit variables to u32 v5: Adressed Ville's review comments. Put the scanline compute function at the place of caller. Removed hwmode flags from uapi and used a local i915 data structure instead. v6: Used vblank hwmode to get the timings. v7: Fixed sparse warnings, indentation and minor review comments. v8: Limited this only for Gen9 DSI.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds IPC support. This patch also enables IPC in all supported platforms based on has_ipc flag. IPC (Isochronous Priority Control) is the hardware feature, which dynamically controls the memory read priority of Display. When IPC is enabled, plane read requests are sent at high priority until filling above the transition watermark, then the requests are sent at lower priority until dropping below the level 0 watermark. The lower priority requests allow other memory clients to have better memory access. When IPC is disabled, all plane read requests are sent at high priority. Changes since V1: - Remove commandline parameter to disable ipc - Address Paulo's comments Changes since V2: - Address review comments - Set ipc_enabled flag Changes since V3: - move ipc_enabled flag assignment inside intel_ipc_enable function Changes since V4: - Re-enable IPC after suspend/resume Changes since V5: - Enable IPC for all gen >=9 except SKL Changes since V6: - fix commit msg - after resume program IPC based on SW state.

* drm/i915: Beef up the IPS vs. CRC workaroundVille Syrjälä2017-08-251-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Oneshot disabling of IPS when CRC capturing is started is insufficient. IPS may get re-enabled by any plane update, and hence tests that keep CRC capturing on across plane updates will start to see inconsistent results as soon as IPS kicks back in. Add a new knob into the crtc state to make sure IPS stays disabled as long as CRC capturing is enabled. Forcing a modeset is the easiest way to handle this since that's already how we do the panel fitter workaround. It's a little heavy handed just for IPS, but seeing as we might already do the panel fitter workaround I think it's better to follow that. We migth want to optimize both cases later if someone gets too upset by the extra delay from the modeset. v2: Check the right thing when deciding whether to force a modeset v3: Rebase, check HAS_IPS before forcing a modeset, move ips_force_disable check into pipe_config_supports_ips() Cc: Paulo Zanoni <paulo.r.zanoni@intel.com> Cc: Daniel Vetter <daniel.vetter@ffwll.ch> Cc: Maarten Lankhorst <maarten.lankhorst@linux.intel.com> Cc: Marta Lofstedt <marta.lofstedt@intel.com> Bugzilla: https://bugs.freedesktop.org/show_bug.cgi?id=101664 Reviewed-by: Paulo Zanoni <paulo.r.zanoni@intel.com> Tested-by: Marta Lofsted <marta.lofstedt@intel.com> #v2 Signed-off-by: Ville Syrjälä <ville.syrjala@linux.intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20170817145509.15549-1-ville.syrjala@linux.intel.com

* drm/i915: Boost GPU clocks if we miss the pageflip's vblankChris Wilson2017-08-221-1/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If we miss the current vblank because the gpu was busy, that may cause a jitter as the frame rate temporarily drops. We try to limit the impact of this by then boosting the GPU clock to deliver the frame as quickly as possible. Originally done in commit 6ad790c0f5ac ("drm/i915: Boost GPU frequency if we detect outstanding pageflips") but was never forward ported to atomic and finally dropped in commit fd3a40242e87 ("drm/i915: Rip out legacy page_flip completion/irq handling"). One of the most typical use-cases for this is a mostly idle desktop. Rendering one frame of the desktop's frontbuffer can easily be accomplished by the GPU running at low frequency, but often exceeds the time budget of the desktop compositor. The result is that animations such as opening the menu, doing a fullscreen switch, or even just trying to move a window around are slow and jerky. We need to respond within a frame to give the best impression of a smooth UX, as a compromise we instead respond if that first frame misses its goal. The result should be a near-imperceivable initial delay and a smooth animation even starting from idle. The cost, as ever, is that we spend more power than is strictly necessary as we overestimate the required GPU frequency and then try to ramp down. This of course is reactionary, too little, too late; nevertheless it is surprisingly effective.

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.

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

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>

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. Changes since V1: - separate out fixed_16_16 wrapper API definition Changes since V2: - Fix buggy crtc !active condition (Maarten) - use intel_wm_plane_visible wrapper as per Maarten's suggestion Changes since V3: - Change failure return from ERANGE to EINVAL Changes since V4: - Rebase based on previous patch changes Changes since V5: - return EINVAL instead of continue (Maarten) Changes since V6: - Improve commit message - Address review comment Changes since V7: - use !enable instead of !active - rename config variable for consistency (Maarten) Signed-off-by: Mahesh Kumar <mahesh1.kumar@intel.com> Reviewed-by: Matt Roper <matthew.d.roper@intel.com> Reviewed-by: Maarten Lankhorst <maarten.lankhorst@linux.intel.com> Signed-off-by: Maarten Lankhorst <maarten.lankhorst@linux.intel.com> Link: http://patchwork.freedesktop.org/patch/msgid/20170526151546.25025-4-mahesh1.kumar@intel.com
* | | drm/i915: Convert intel_sdvo connector properties to atomic.Maarten Lankhorst2017-05-301-6/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

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.
