2018-06-19drm/i915: Allow DBLSCAN user modes with eDP/LVDS/DSIVille Syrjälä1-0/+6
When encountering a connector with the scaling mode property both intel and modesetting ddxs sometimes add tons of DBLSCAN modes to the output's mode list. The idea presumably being that since the output will be going through the panel fitter anyway we can pretend to use any kind of mode. Sadly that means we can't reject user modes with the DBLSCAN flag until we know whether we're going to be using the panel's native mode or the user mode directly. Doing otherwise means X clients using xf86vidmode/xrandr will get a protocol error (and often self terminate as a result) when the kernel refuses to use the requested mode with the DBLSCAN flag. To undo the regression we'll move the DBLSCAN checks into the connector->mode_valid() and encoder->compute_config() hooks.

2018-04-07drm/i915/dp: Send DPCD ON for MST before phy_upLyude Paul1-1/+7
When doing a modeset where the sink is transitioning from D3 to D0 , it would sometimes be possible for the initial power_up_phy() to start timing out. This would only be observed in the last action before the sink went into D3 mode was intel_dp_sink_dpms(DRM_MODE_DPMS_OFF). We originally thought this might be an issue with us accidentally shutting off the aux block when putting the sink into D3, but since the DP spec mandates that sinks must wake up within 1ms while we have 100ms to respond to an ESI irq, this didn't really add up. Turns out that the problem is more subtle then that: It turns out that the timeout is from us not enabling DPMS on the MST hub before actually trying to initiate sideband communications. This would cause the first sideband communication (power_up_phy()), to start timing out because the sink wasn't ready to respond. Afterwards, we would call intel_dp_sink_dpms(DRM_MODE_DPMS_ON) in intel_ddi_pre_enable_dp(), which would actually result in waking up the sink so that sideband requests would work again. Since DPMS is what lets us actually bring the hub up into a state where sideband communications become functional again, we just need to make sure to enable DPMS on the display before attempting to perform sideband communications. Changes since v1: - Remove comment above if (!intel_dp->is_mst) - vsryjala - Move intel_dp_sink_dpms() for MST into intel_dp_post_disable_mst() to keep enable/disable paths symmetrical - Improve commit message - dhnkrn Changes since v2: - Only send DPMS off when we're disabling the last sink, and only send DPMS on when we're enabling the first sink - dhnkrn Changes since v3: - Check against is_mst, not intel_dp->is_mst - dhnkrn/vsyrjala Signed-off-by: Lyude Paul <lyude@redhat.com> Reviewed-by: Dhinakaran Pandiyan <dhinakaran.pandiyan@intel.com> Reviewed-by: Ville Syrjälä <ville.syrjala@linux.intel.com> Tested-by: Laura Abbott <labbott@redhat.com> Cc: stable@vger.kernel.org Fixes: ad260ab32a4d9 ("drm/i915/dp: Write to SET_POWER dpcd to enable MST hub.")

As a nice bonus we get more cross checking as intel_ddi_get_config() will populate output_types based on the actual mode of the DDI port.

2017-10-30drm/i915: Pass a crtc state to ddi post_disable from MST codeVille Syrjälä1-3/+3
Pass an old crtc state to intel_ddi_post_disable() from the MST code. Note that this crtc state won't necessaitly match the one that was passed to intel_ddi_pre_enable() if the first stream to be enabled isn't the last stream to be disabled. But this is fine since the states should be identical in every important way. This does mean people frobbing the DDI pre_enable/post_disable hooks have to pay attention in what parts of the state they consult. The alternative would be to inline the relevant code into the MST code. That is actually what we used to do for pre_enable before commit e081c8463ac9 ("drm/i915: Remove duplicate DDI enabling logic from MST path").

2017-10-25drm/i915: Adjust system agent voltage on CNL if required by DDI portsVille Syrjälä1-0/+5
On CNL we may need to bump up the system agent voltage not only due to CDCLK but also when driving DDI port with a sufficiently high clock. To that end start tracking the minimum acceptable voltage for each crtc. We do the tracking via crtcs because we don't have any kind of encoder state. Also there's no downside to doing it this way, and it matches how we track cdclk requirements on account of pixel rate. v2: Allow disabled crtcs to use the min voltage Add IS_CNL check to intel_ddi_compute_min_voltage() since we're using CNL specific values there s/intel_compute_min_voltage/cnl_compute_min_voltage/ since the function makes hw specific assumptions about the voltage values v3: Drop the test hack leftovers from skl_modeset_calc_cdclk() v4: s/voltage/voltage_level/ (Rodrigo) Replace DPLL DVFS FIXMEs with an explanation why we don't do anything there (Rodrigo) Cc: Mika Kahola <mika.kahola@intel.com> Cc: Manasi Navare <manasi.d.navare@intel.com> Cc: Rodrigo Vivi <rodrigo.vivi@intel.com> Signed-off-by: Ville Syrjälä <ville.syrjala@linux.intel.com> Reviewed-by: Rodrigo Vivi <rodrigo.vivi@intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20171024095216.1638-9-ville.syrjala@linux.intel.com

The Analogix 7737 DP to HDMI converter requires reduced M and N values when to operate correctly at HBR2. We tried to reduce the M/N values for all devices in commit 9a86cda07af2 ("drm/i915/dp: reduce link M/N parameters"), but that regressed some other sinks.

Use the added helpers to track MST link bandwidth for atomic modesets. Link bw is acquired in the ->atomic_check() phase when CRTCs are being enabled with drm_atomic_find_vcpi_slots(). Similarly, link bw is released during ->atomic_check() with the connector helper callback ->atomic_check() when CRTCs are disabled. v6: active_changed does not alter vcpi allocations (Maarten) v5: Implement connector->atomic_check() in place of atomic_release() v4: Return an int from intel_dp_mst_atomic_release() (Maarten) v3: Handled the case where ->atomic_release() is called more than once during an atomic_check() for the same state. v2: Squashed atomic_release() implementation and caller (Daniel) Fixed logic for connector-crtc switching case (Daniel) Fixed logic for suspend-resume case.

2017-02-01drm/i915: Fix POWER_DOMAIN_AUDIO refcounting.Maarten Lankhorst1-7/+2
If the crtc was brought up with audio before the driver loads, then crtc_disable will remove a refcount to audio that doesn't exist before. Fortunately we already set power domains on readout, so we can just add the power domain handling to get_crtc_power_domains, which will update the power domains correctly in all cases. This was found when testing module reload on CI with the crtc enabled, which resulted in the following warn after module reload + modeset: [ 24.197041] ------------[ cut here ]------------ [ 24.197075] WARNING: CPU: 0 PID: 99 at drivers/gpu/drm/i915/intel_runtime_pm.c:1790 intel_display_power_put+0x134/0x140 [i915] [ 24.197076] Use count on domain AUDIO is already zero [ 24.197098] CPU: 0 PID: 99 Comm: kworker/u8:2 Not tainted 4.9.0-CI-Trybot_393+ #1 [ 24.197099] Hardware name: /NUC6i5SYB, BIOS SYSKLi35.86A.0042.2016.0409.1246 04/09/2016 [ 24.197102] Workqueue: events_unbound async_run_entry_fn [ 24.197105] ffffc900003c7688 ffffffff81435b35 ffffc900003c76d8 0000000000000000 [ 24.197107] ffffc900003c76c8 ffffffff8107e4d6 000006fe5dc36f28 ffff88025dc30054 [ 24.197109] ffff88025dc36f28 ffff88025dc30000 ffff88025dc30000 0000000000000015 [ 24.197110] Call Trace: [ 24.197113] [<ffffffff81435b35>] dump_stack+0x67/0x92 [ 24.197116] [<ffffffff8107e4d6>] __warn+0xc6/0xe0 [ 24.197118] [<ffffffff8107e53a>] warn_slowpath_fmt+0x4a/0x50 [ 24.197149] [<ffffffffa039b4b4>] intel_display_power_put+0x134/0x140 [i915] [ 24.197187] [<ffffffffa04217dd>] intel_disable_ddi+0x4d/0x80 [i915] [ 24.197223] [<ffffffffa03f388f>] intel_encoders_disable.isra.74+0x7f/0x90 [i915] [ 24.197257] [<ffffffffa03f6c05>] haswell_crtc_disable+0x55/0x170 [i915] [ 24.197292] [<ffffffffa03fec88>] intel_atomic_commit_tail+0x108/0xfd0 [i915] [ 24.197295] [<ffffffff810d47c6>] ? __lock_is_held+0x66/0x90 [ 24.197330] [<ffffffffa03fff79>] intel_atomic_commit+0x429/0x560 [i915] [ 24.197332] [<ffffffff81570186>] ?drm_atomic_add_affected_connectors+0x56/0xf0 [ 24.197334] [<ffffffff8156f726>] drm_atomic_commit+0x46/0x50 [ 24.197336] [<ffffffff81553f87>] restore_fbdev_mode+0x147/0x270 [ 24.197337] [<ffffffff81555bee>] drm_fb_helper_restore_fbdev_mode_unlocked+0x2e/0x70 [ 24.197339] [<ffffffff81555aa8>] drm_fb_helper_set_par+0x28/0x50 [ 24.197374] [<ffffffffa041c7d3>] intel_fbdev_set_par+0x13/0x70 [i915] [ 24.197376] [<ffffffff8149e07a>] fbcon_init+0x57a/0x600 [ 24.197379] [<ffffffff81514b71>] visual_init+0xd1/0x130 [ 24.197381] [<ffffffff8151603c>] do_bind_con_driver+0x1bc/0x3a0 [ 24.197384] [<ffffffff81516521>] do_take_over_console+0x111/0x180 [ 24.197386] [<ffffffff8149e152>] do_fbcon_takeover+0x52/0xb0 [ 24.197387] [<ffffffff814a12c3>] fbcon_event_notify+0x723/0x850 [ 24.197390] [<ffffffff810a4830>] ?__blocking_notifier_call_chain+0x30/0x70 [ 24.197392] [<ffffffff810a44a4>] notifier_call_chain+0x34/0xa0 [ 24.197394] [<ffffffff810a4848>] __blocking_notifier_call_chain+0x48/0x70 [ 24.197397] [<ffffffff810a4881>] blocking_notifier_call_chain+0x11/0x20 [ 24.197398] [<ffffffff814a4556>] fb_notifier_call_chain+0x16/0x20 [ 24.197400] [<ffffffff814a678c>] register_framebuffer+0x24c/0x330 [ 24.197402] [<ffffffff815558d9>] drm_fb_helper_initial_config+0x219/0x3c0 [ 24.197436] [<ffffffffa041d373>] intel_fbdev_initial_config+0x13/0x30 [i915] [ 24.197438] [<ffffffff810a5d44>] async_run_entry_fn+0x34/0x140 [ 24.197440] [<ffffffff8109c26c>] process_one_work+0x1ec/0x6b0 [ 24.197442] [<ffffffff8109c1e6>] ? process_one_work+0x166/0x6b0 [ 24.197445] [<ffffffff8109c779>] worker_thread+0x49/0x490 [ 24.197447] [<ffffffff8109c730>] ? process_one_work+0x6b0/0x6b0 [ 24.197448] [<ffffffff810a2a9b>] kthread+0xeb/0x110 [ 24.197451] [<ffffffff810a29b0>] ? kthread_park+0x60/0x60 [ 24.197453] [<ffffffff818241a7>] ret_from_fork+0x27/0x40 [ 24.197476] ---[ end trace bda64b683b8e8162 ]--- Signed-off-by: Maarten Lankhorst <maarten.lankhorst@linux.intel.com> Link: http://patchwork.freedesktop.org/patch/msgid/1481812185-19098-3-git-send-email-maarten.lankhorst@linux.intel.com Reviewed-by: Daniel Vetter <daniel.vetter@ffwll.ch>

2017-01-26drm/i915: Add support for DP Video pattern compliance testsManasi Navare1-1/+6
The intel_dp_autotest_video_pattern() function gets invoked through the compliance test handler on a HPD short pulse if the test type is set to DP_TEST_VIDEO_PATTERN. This performs the DPCD registers reads to read the requested test pattern, video pattern resolution, frame rate and bits per color value. The results of this analysis are handed off to userspace so that the userspace app can set the video pattern mode appropriately for the test result/response. When the test is requested with specific BPC value, we read the BPC value from the DPCD register. If this BPC value in intel_dp structure has a non-zero value and we're on a display port connector, then we use the value to calculate the bpp for the pipe. Also in this case if its a 18bpp video pattern request, then we force the dithering on pipe to be disabled since it causes CRC mismatches. The compliance_test_active flag is set at the end of the individual test handling functions. This is so that the kernel-side operations can be completed without the risk of interruption from the userspace app that is polling on that flag. v5: * Remove test_result variable * Populate the compliance test data at the end of the function (Jani Nikula) v4: *Return TEST_NAK on read failures and invalid values (Jani Nikula) * Address CRC mismatch errors v3: * Use the updated properly shifted bit definitions (Jani Nikula) * Force dithering to be disabled on 18bpp compliance test request (Manasi Navare) v2: * Updated the DPCD Register reads based on proper defines in header (Jani Nikula) * Squahsed the patch that forced the pipe bpp to compliance test bpp (Jani Nikula) Signed-off-by: Manasi Navare <manasi.d.navare@intel.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: Jani Nikula <jani.nikula@intel.com> Link: http://patchwork.freedesktop.org/patch/msgid/1485274909-17470-1-git-send-email-manasi.d.navare@intel.com

2016-09-21drm/i915: Store port enum in intel_encoderPandiyan, Dhinakaran1-0/+1
Storing the port enum in intel_encoder makes it convenient to know the port attached to an encoder. Moving the port information up from intel_digital_port to intel_encoder avoids unecessary intel_digital_port access and handles MST encoders cleanly without requiring conditional checks for them (thanks danvet). v2: Renamed the port enum member from 'attached_port' to 'port' (danvet) Fixed missing initialization of port in intel_sdvo.c (danvet) v3: Fixed missing initialization of port in intel_crt.c (Ville) v4: Storing port for DVO encoders too.

2016-09-07drm/i915: Remove ddi_pll_sel from intel_crtc_stateAnder Conselvan de Oliveira1-1/+2
The value of ddi_pll_sel is derived from the selection of shared dpll, so just calculate the final value when necessary. v2: Actually remove it from crtc state and delete remaining usages.

2016-08-23drm/i915: Remove unused loop from intel_dp_mst_compute_configMaarten Lankhorst1-18/+1
Now that conn_state is passed in as argument to compute_config, it's guaranteed that there is a connector for the argument. The code that looks for the connector is now dead, and completely unused.

2016-08-23drm/i915: Pass crtc_state and connector_state to encoder functionsMaarten Lankhorst1-5/+15
This is mostly code churn, with exception of a few places: - intel_display.c has changes in intel_sanitize_encoder - intel_ddi.c has intel_ddi_fdi_disable calling intel_ddi_post_disable, and required a function change. Also affects intel_display.c - intel_dp_mst.c passes a NULL crtc_state and conn_state to intel_ddi_post_disable for shutting down the real encoder. If we would pass conn_state, then conn_state->connector != intel_dig_port->connector and conn_state->best_encoder != to_intel_encoder(intel_dig_port). We also shouldn't pass crtc_state, because in that case the disabling sequence may potentially be different depending on which crtc is disabled last. Nice way to introduce bugs. No other functional changes are done, diff stat is already huge. Each encoder type will need to be fixed to use the atomic states separately.

This reverts commit f64425a82bdb5c3d7e09ba765716da88a9b00eec. active_streams will get totally out of whack with SST unless we sync up with the hw state at readout, obviously! We don't yet do that, so now the WARNs fire all the time.
