2015-10-06drm/i915: Rename DP link training functionsAnder Conselvan de Oliveira
The link training functions had confusing names. The start function actually does the clock recovery phase of the link training, and the complete function does the channel equalization. So call them that instead. Also, every call to intel_dp_start_link_train() was followed by a call to intel_dp_complete_link_train(), so add a new start function that calls clock_recory and channel_equalization.

2015-10-02drm/dp/mst: split connector registration into two parts (v2)Dave Airlie
In order to cache the EDID properly for tiled displays, we need to retrieve it before we register the connector with userspace, otherwise userspace can call get resources and try and get the edid before we've even cached it. This fixes some problems when hotplugging mst monitors, with X/mutter running. As mutter seems to get 0 modes for one of the monitors in the tile. v2: fix warning in radeon handle tile setting in cached path rather than get edid path.

2015-09-30drm/i915: Always use crtc_ timings when dealing with adjustead_modeVille Syrjälä
The adjustead_mode crtc_ timings are what we will program into the hardware, so it's those timings we should be looking practically everywhere. The normal and crtc_ timings should differ only when stere doubling is used. In that case the normal timings are the orignal non-doubled timigns, and crtc_ timings are the doubled timings used by the hardware. The only case where we continue to look at the normal timings is when we pass the adjusted_mode to drm_match_{cea,hdmi}_mode() to find the VIC. drm_edid keeps the modes aronund in the non-double form only, so it needs the non-double timings to match against.

2015-09-01i915: Set ddi_pll_sel in DP MST pathAnder Conselvan de Oliveira
The DP MST encoder config function never sets ddi_pll_sel, even though its value is programmed in its ->pre_enable() hook. That used to work because a new pipe_config was kzalloc'ed at every modeset, and the value of zero selects the highest clock for the PLL. Starting with the commit below, the value of ddi_pll_sel is preserved through modesets, and since the correct value wasn't properly setup by the MST code, it could lead to warnings and blank screens. commit 8504c74c7ae48b4b8ed1f1c0acf67482a7f45c93 Author: Ander Conselvan de Oliveira <ander.conselvan.de.oliveira@intel.com> Date: Fri May 15 11:51:50 2015 +0300 drm/i915: Preserve ddi_pll_sel when allocating new pipe_config Bugzilla: https://bugs.freedesktop.org/show_bug.cgi?id=91628 Cc: stable@vger.kernel.org # 7e6313a2516d drm/i915: Don't use link_bw for PLL setup Cc: stable@vger.kernel.org Cc: Timo Aaltonen <tjaalton@ubuntu.com> Cc: Luciano Coelho <luciano.coelho@intel.com> Signed-off-by: Ander Conselvan de Oliveira <ander.conselvan.de.oliveira@intel.com> Reviewed-by: Ville Syrjälä <ville.syrjala@linux.intel.com> Signed-off-by: Jani Nikula <jani.nikula@intel.com>
2015-08-26drm/i915: Put back lane_count into intel_dp and add link_rate tooVille Syrjälä
With MST there won't be a crtc assigned to the main link encoder, so trying to dig up the pipe_config from there is a recipe for an oops. Instead store the parameters (lane_count and link_rate) in the encoder, and use those values during link training etc. Since those parameters are now assigned only when the link is actually enabled, .compute_config() won't clobber them as it did before. Hardware state readout is still bonkers though as we don't transfer the link parameters from pipe_config intel_dp. We should do that during encoder sanitation. But since we don't even do a proper job of reading out the main link encoder state for MST there's littel point in worrying about this now.

In commit 8c7b5ccb729870e606321b3703e2c2e698c49a95 Author: Ander Conselvan de Oliveira <ander.conselvan.de.oliveira@intel.com> Date: Tue Apr 21 17:13:19 2015 +0300 drm/i915: Use atomic helpers for computing changed flags we've switched over to the atomic version to compute the crtc->encoder->connector routing from the i915 variant. That one relies upon the ->best_encoder callback, but the i915-private version relied upon intel_find_encoder. Which didn't matter except for dp mst, where the encoder depends upon the selected crtc. Fix this functional bug by implemented a correct atomic-state based encoder selector for dp mst. Note that we can't get rid of the legacy best_encoder callback since the fbdev emulation uses that still. That means it's incorrect there still, but that's been the case ever since i915 dp mst support was merged so not a regression. Best to fix that by converting fbdev over to atomic too.

2015-07-22drm/i915: Take all modeset locks for DP MST hotplugDaniel Vetter
While auditing various users of the connector/encoder lists I realized that the atomic code is a very prolific user of them. And it only ever grabs the mode_config->connection_mutex, but not the mode_config->mutex like all the other code walking encoder/connector lists. The problem is that we can't grab the mode_config.mutex late in atomic code since that would lead to locking inversions. And we don't want to grab it unconditionally like the legacy set_config modeset path since that would render all the fine-grained locking moot. Instead just grab more locks in the dp mst hotplug code. Note that drm_connector_init (which is the one adding the connector to these lists) already uses drm_modeset_lock_all. The other reason for grabbing all locks is that the dpms off in the unplug function amounts to a modeset, so better to take all required locks for that.

As soon as that bit gets set, the DRM core will start adding atomic connector properties (in addition to the plane properties we care about at the moment), so we need to be able to handle the new way the DRM core will interact with us. For simplicity, we just lookup driver-specific connector properties in the usual shadow array maintained by the core.

Create a dummy connector state for each connector at init time to ensure the DRM core doesn't try to dereference a NULL connector->state. The actual connector properties will never be updated or contain useful information, but since we're doing this specifically for testing/debug of the plane operations (and only when a specific kernel module option is given), that shouldn't really matter.

2015-01-27drm/i915: Make intel_crtc->config a pointerAnder Conselvan de Oliveira
To match the semantics of drm_crtc->state, which this will eventually become. The allocation of the memory for config will be fixed in a followup patch. By adding the extra _config field to intel_crtc it was possible to generate this entire patch with the cocci script below. @@ @@ struct intel_crtc { ... -struct intel_crtc_state config; +struct intel_crtc_state _config; +struct intel_crtc_state *config; ... } @@ struct intel_crtc *crtc; @@ -memset(&crtc->config, 0, sizeof(crtc->config)); +memset(crtc->config, 0, sizeof(*crtc->config)); @@ @@ __intel_set_mode(...) { <... -to_intel_crtc(crtc)->config = *pipe_config; +(*(to_intel_crtc(crtc)->config)) = *pipe_config; ...> } @@ @@ intel_crtc_init(...) { ...

2014-07-22drm/i915: add DP 1.2 MST support (v0.7)Dave Airlie
This adds DP 1.2 MST support on Haswell systems. Notes: a) this reworks irq handling for DP MST ports, so that we can avoid the mode config locking in the current hpd handlers, as we need to process up/down msgs at a better time. Changes since v0.1: use PORT_PCH_HOTPLUG to detect short vs long pulses add a workqueue to deal with digital events as they can get blocked on the main workqueue beyong mode_config mutex fix a bunch of modeset checker warnings acks irqs in the driver cleanup the MST encoders Changes since v0.2: check irq status again in work handler move around bring up and tear down to fix DPMS on/off use path properties. Changes since v0.3: updates for mst apis more state checker fixes irq handling improvements fbcon handling support improved reference counting of link - fixes redocking. Changes since v0.4: handle gpu reset hpd reinit without oopsing check link status on HPD irqs fix suspend/resume Changes since v0.5: use proper functions to get max link/lane counts fix another checker backtrace - due to connectors disappearing. set output type in more places fro, unknown->displayport don't talk to devices if no HPD asserted check mst on short irqs only check link status properly rebase onto prepping irq changes. drop unsued force_act Changes since v0.6: cleanup unused struct entry.
