2021-10-14drm/i915: Remove dead DKL_TX_LOADGEN_SHARING_PMD_DISABLE stuffVille Syrjälä
DKL_TX_LOADGEN_SHARING_PMD_DISABLE doesn't even seem to exist, also the spec says to skip all loadgen stuff. The code was dead anyway since it wasn't actually writing the value anywhere.

2021-10-14drm/i915/bios: gracefully disable dual eDP for nowJani Nikula
For the time being, neither the power sequencer nor the backlight code properly support two eDP panels simultaneously. While the software states will be independent, the same sets of registers will be used for both eDP panels, clobbering the hardware state and leading to errors. Gracefully disable dual eDP until proper support has been added.

Register a privacy-screen device on laptops with a privacy-screen, this exports the PrivacyGuard features to user-space using a standardized vendor-agnostic sysfs interface. Note the sysfs interface is read-only. Registering a privacy-screen device with the new privacy-screen class code will also allow the GPU driver to get a handle to it and export the privacy-screen setting as a property on the DRM connector object for the LCD panel. This DRM connector property is a new standardized interface which all user-space code should use to query and control the privacy-screen.

2021-10-14drm/connector: Add a drm_connector privacy-screen helper functions (v2)Hans de Goede
Add 2 drm_connector privacy-screen helper functions: 1. drm_connector_attach_privacy_screen_provider(), this function creates and attaches the standard privacy-screen properties and registers a generic notifier for generating sysfs-connector-status-events on external changes to the privacy-screen status. 2. drm_connector_update_privacy_screen(), update the privacy-screen's sw_state if the connector has a privacy-screen. Changes in v2: - Do not update connector->state->privacy_screen_sw_state on atomic-commits. - Change drm_connector_update_privacy_screen() to take drm_connector_state as argument instead of a full drm_atomic_state. This allows the helper to be called by drivers when they are enabling crtcs/encoders/connectors.

2021-10-14drm: Add privacy-screen class (v4)Hans de Goede
On some new laptops the LCD panel has a builtin electronic privacy-screen. We want to export this functionality as a property on the drm connector object. But often this functionality is not exposed on the GPU but on some other (ACPI) device. This commit adds a privacy-screen class allowing the driver for these other devices to register themselves as a privacy-screen provider; and allowing the drm/kms code to get a privacy-screen provider associated with a specific GPU/connector combo. Changes in v2: - Make CONFIG_DRM_PRIVACY_SCREEN a bool which controls if the drm_privacy code gets built as part of the main drm module rather then making it a tristate which builds its own module. - Add a #if IS_ENABLED(CONFIG_DRM_PRIVACY_SCREEN) check to drm_privacy_screen_consumer.h and define stubs when the check fails. Together these 2 changes fix several dependency issues. - Remove module related code now that this is part of the main drm.ko - Use drm_class as class for the privacy-screen devices instead of adding a separate class for this Changes in v3: - Make the static inline drm_privacy_screen_get_state() stub set sw_state and hw_state to PRIVACY_SCREEN_DISABLED to squelch an uninitialized variable warning when CONFIG_DRM_PRIVICAY_SCREEN is not set Changes in v4: - Make drm_privacy_screen_set_sw_state() skip calling out to the hw if hw_state == new_sw_state Reviewed-by: Emil Velikov <emil.l.velikov@gmail.com> Reviewed-by: Lyude Paul <lyude@redhat.com> Signed-off-by: Hans de Goede <hdegoede@redhat.com> Link: https://patchwork.freedesktop.org/patch/msgid/20211005202322.700909-3-hdegoede@redhat.com

The xrandr command shows all possible enum values separated by commas in its output, so having a comma in an enum name is not a good idea. - Do not add a privacy_screen_hw_state member to drm_connector_state since this property is immutable its value must be directly stored in the obj->properties->values array Signed-off-by: Rajat Jain <rajatja@google.com> Acked-by: Pekka Paalanen <pekka.paalanen@collabora.com> Reviewed-by: Mario Limonciello <Mario.limonciello@dell.com> Reviewed-by: Emil Velikov <emil.l.velikov@gmail.com> Reviewed-by: Lyude Paul <lyude@redhat.com> Co-developed-by: Hans de Goede <hdegoede@redhat.com> Signed-off-by: Hans de Goede <hdegoede@redhat.com> Link: https://patchwork.freedesktop.org/patch/msgid/20211005202322.700909-2-hdegoede@redhat.com

2021-10-13drm/locking: add backtrace for locking contended locks without backoffJani Nikula
If drm_modeset_lock() returns -EDEADLK, the caller is supposed to drop all currently held locks using drm_modeset_backoff(). Failing to do so will result in warnings and backtraces on the paths trying to lock a contended lock. Add support for optionally printing the backtrace on the path that hit the deadlock and didn't gracefully handle the situation. For example, the patch [1] inadvertently dropped the return value check and error return on replacing calc_watermark_data() with intel_compute_global_watermarks(). The backtraces on the subsequent locking paths hitting WARN_ON(ctx->contended) were unhelpful, but adding the backtrace to the deadlock path produced this helpful printout: <7> [98.002465] drm_modeset_lock attempting to lock a contended lock without backoff: drm_modeset_lock+0x107/0x130 drm_atomic_get_plane_state+0x76/0x150 skl_compute_wm+0x251d/0x2b20 [i915] intel_atomic_check+0x1942/0x29e0 [i915] drm_atomic_check_only+0x554/0x910 drm_atomic_nonblocking_commit+0xe/0x50 drm_mode_atomic_ioctl+0x8c2/0xab0 drm_ioctl_kernel+0xac/0x140 Add new CONFIG_DRM_DEBUG_MODESET_LOCK to enable modeset lock debugging with stack depot and trace.

The I915_TILING_* definitions in the uapi header are intended solely for tiling modes that are visible to the old de-tiling fence ioctls. Since modern hardware does not support de-tiling fences, we should not add new definitions for new tiling types going forward. However we do want the client blit selftest to eventually cover other new tiling modes (such as Tile4), so switch it to using its own enum of tiling modes.

2021-10-12drm/i915/dg2: update link training for 128b/132bJani Nikula
The 128b/132b channel coding link training uses more straightforward TX FFE preset values. Reuse voltage tries and max vswing for retry logic. The delays for 128b/132b are still all wrong, but this is regardless a step forward. v2: Fix UHBR rate checks, use intel_dp_is_uhbr() helper v3: - Rebase - Modify intel_dp_adjust_request_changed() and intel_dp_link_max_vswing_reached() to take 128b/132b into account. (Ville) v4: - Train request printing for TX FFE (Ville) - Log 8b/10b vs. 128b/132b (Ville) - Add helper for per-lane max vswing / tx ffe (Ville) - Name functions with tx_ffe/vswing instead of 128b132b/8b10b Cc: Ville Syrjälä <ville.syrjala@linux.intel.com> Reviewed-by: Ville Syrjälä <ville.syrjala@linux.intel.com> Signed-off-by: Jani Nikula <jani.nikula@intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20211011182144.22074-2-jani.nikula@intel.com
