Seems that GLK has a dotclock that's twice the display clock. skl_max_scale checks for IS_GEMINILAKE, so perform the same check here. While at it, change the DRM_ERROR to DEBUG_KMS.

Commit 7c3f86b6 ("drm/i915: Invalidate the guc ggtt TLB upon insertion") added the restoration of the invalidation routine after the GuC was disabled, but missed that the GuC was unconditionally disabled when not used. This then overwrites the invalidate routine for the older chipsets, causing havoc and breaking resume as the most obvious victim. We place the guard inside i915_ggtt_disable_guc() to be backport friendly (the bug was introduced into v4.11) but it would be preferred to be in more control over when this was guard (i.e. do not try and teardown the data structures before we have enabled them). That should be true with the reorganisation of the guc loaders. Reported-by:

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. 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:Matt Roper <matthew.d.roper@intel.com> Reviewed-by:

This patch implements new DDB allocation algorithm as per HW team recommendation. This algo takecare of scenario where we allocate less DDB for the planes with lower relative pixel rate, but they require more DDB to work. It also takes care of enabling same watermark level for each plane in crtc, for efficient power saving. Changes since v1: - Rebase on top of Paulo's patch series Changes since v2: - Fix the for loop condition to enable WM Changes since v3: - Fix crash in cursor i-g-t reported by Maarten - Rebase after addressing Paulo's comments - Few other ULT fixes Changes since v4: - Rebase on drm-tip - Added separate function to enable WM levels Changes since v5: - Fix a crash identified in skl-6770HQ system Changes since v6: - Address review comments from Matt Changes since v7: - Fix failure return in skl_compute_plane_wm (Matt) - fix typo Changes since v8: - Always check cursor wm enable irrespective of total_data_rate Changes since v9: - fix typo Signed-off-by:

On some systems there can be a race condition in which no crtc state is added to the first atomic commit. This results in all crtc's having a null DDB allocation, causing a FIFO underrun on any update until the first modeset. Changes since v1: - Do not take the connection_mutex, this is already done below. Reported-by:

Since commit bac2a909 Author: Rafael J. Wysocki <rafael.j.wysocki@intel.com> Date: Wed Jan 21 02:17:42 2015 +0100 PCI / PM: Avoid resuming PCI devices during system suspend PCI devices will default to allowing the system suspend complete optimization where devices are not woken up during system suspend if they were already runtime suspended. This however breaks the i915/HDA drivers for two reasons: - The i915 driver has system suspend specific steps that it needs to run, that bring the device to a different state than its runtime suspended state. - The HDA driver's suspend handler requires power that it will request from the i915 driver's power domain handler. This in turn requires the i915 driver to runtime resume itself, but this won't be possible if the suspend complete optimization is in effect: in this case the i915 runtime PM is disabled and trying to get an RPM reference returns -EACCESS. Solve this by requiring the PCI/PM core to resume the device during system suspend which in effect disables the suspend complete optimization. Regardless of the above commit the optimization stayed disabled for DRM devices until commit d14d2a84 Author: Lukas Wunner <lukas@wunner.de> Date: Wed Jun 8 12:49:29 2016 +0200 drm: Remove dev_pm_ops from drm_class so this patch is in practice a fix for this commit. Another reason for the bug staying hidden for so long is that the optimization for a device is disabled if it's disabled for any of its children devices. i915 may have a backlight device as its child which doesn't support runtime PM and so doesn't allow the optimization either. So if this backlight device got registered the bug stayed hidden. Credits to Marta, Tomi and David who enabled pstore logging, that caught one instance of this issue across a suspend/ resume-to-ram and Ville who rememberd that the optimization was enabled for some devices at one point.

We are passing parameters in the wrong order to find next zero bit, and when it doesn't find anything it returns size (offset in the code), which is always zero. For reference the function is defined as: find_next_bit( *addr, size, offset ) The incorrect parameter order was added by commit abddffdf ("drm/i915/guc: Sanitize GuC client initialization"). Luckily, currently we only use a single guc client and a single doorbell, which happens to be zero; therefore it isn't necessary to backport this fix (which would be for v4.12).

Allow intel_engine_is_idle() to be called outside of the GT wakeref by acquiring the device runtime pm for ourselves. This allows the function to act as check after we assume the engine is idle and we release the GT wakeref held whilst we have requests. At the moment, we do not call it outside of an awake context but taking the wakeref as required makes it more convenient to use for quick debugging in future.

I have a plan to write a quick test to exercise concurrent usage of i915_gem_shrink(), the simplest way looks to be to have multiple threads using debugfs/i915_drop_caches. However, we currently take one lock over the entire function, serialising the calls into i915_gem_shrink() so reduce the lock coverage. Testcase: igt/gem_shrink/reclaim Signed-off-by:

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. Signed-off-by:

Do the same as other connectors, attempt to detect hdmi audio in the detect() callback, and only use the force_audio property as override. Compute has_audio in pipe_config, and use that value instead of the probed value directly. Signed-off-by:

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.

None of the intel connectors can use all types of scaling modes, so only try the ones that are possible. This is another preparation for connectors towards conversion to atomic. Signed-off-by:

The first step in converting connector properties to atomic is wiring up the atomic state. We're still not completely supoprting the scaling mode in the atomic case, but this is the first step towards it. Signed-off-by:
