2024-09-03drm/display: split DSC helpers from DP helpersDmitry Baryshkov
Currently the DRM DSC functions are selected by the DRM_DISPLAY_DP_HELPER Kconfig symbol. This is not optimal, since the DSI code (both panel and host drivers) end up selecting the seemingly irrelevant DP helpers. Split the DSC code to be guarded by the separate DRM_DISPLAY_DSC_HELPER Kconfig symbol.

2024-02-27drm/i915/dp: Add support for DP tunnel BW allocationImre Deak
Add support to enable the DP tunnel BW allocation mode. Follow-up patches will call the required helpers added here to prepare for a modeset on a link with DP tunnels, the last change in the patchset actually enabling BWA. With BWA enabled, the driver will expose the full mode list a display supports, regardless of any BW limitation on a shared (Thunderbolt) link. Such BW limits will be checked against only during a modeset, when the driver has the full knowledge of each display's BW requirement. If the link BW changes in a way that a connector's modelist may also change, userspace will get a hotplug notification for all the connectors sharing the same link (so it can adjust the mode used for a display). The BW limitation can change at any point, asynchronously to modesets on a given connector, so a modeset can fail even though the atomic check for it passed. In such scenarios userspace will get a bad link notification and in response is supposed to retry the modeset. v2: - Fix old vs. new connector state in intel_dp_tunnel_atomic_check_state(). (Ville) - Fix propagating the error from intel_dp_tunnel_atomic_compute_stream_bw(). (Ville) - Move tunnel==NULL checks from driver to DRM core helpers. (Ville) - Simplify return flow from intel_dp_tunnel_detect(). (Ville) - s/dp_tunnel_state/inherited_dp_tunnels (Ville) - Simplify struct intel_dp_tunnel_inherited_state. (Ville) - Unconstify object pointers (vs. states) where possible. (Ville) - Init crtc_state while declaring it in check_group_state(). (Ville) - Join obj->base.id, obj->name arg lines in debug prints to reduce LOC. (Ville) - Add/rework intel_dp_tunnel_atomic_alloc_bw() to prepare for moving the BW allocation from encoder hooks up to intel_atomic_commit_tail() later in the patchset. - Disable BW alloc mode during system suspend. - Allocate the required BW for all tunnels during system resume. - Add intel_dp_tunnel_atomic_clear_stream_bw() instead of the open-coded sequence in a follow-up patch. - Add function documentation to all exported functions. - Add CONFIG_USB4 dependency to CONFIG_DRM_I915_DP_TUNNEL. v3: - Rebase on intel_dp_get_active_pipes() change in previous patch.

For development and testing purposes, the i915.force_probe module parameter and DRM_I915_FORCE_PROBE kconfig option allow probing of devices that aren't supported by the driver. The i915.force_probe module parameter is "unsafe" and setting it taints the kernel. However, using the kconfig option does not.

2023-01-05drm/i915: Expand force_probe to block probe of devices as well.Rodrigo Vivi
There are new cases where we want to block i915 probe, such as when experimenting or developing the new Xe driver. But also, with the new hybrid cards, users or developers might want to use i915 only on integrated and fully block the probe of the i915 for the discrete. Or vice versa. There are even older development and validation reasons, like when you use some distro where the modprobe.blacklist is not present. But in any case, let's introduce a more granular control, but without introducing yet another parameter, but using the existent force_probe one. Just by adding a ! in the begin of the id in the force_probe, like in this case where we would block the probe for Alder Lake: $ insmod i915.ko force_probe='!46a6' v2: Take care of '*' and '!*' cases as pointed out by Gustavo and Jani.

2022-09-03ACPI: video: Add Nvidia WMI EC brightness control detection (v3)Hans de Goede
On some new laptop designs a new Nvidia specific WMI interface is present which gives info about panel brightness control and may allow controlling the brightness through this interface when the embedded controller is used for brightness control. When this WMI interface is present and indicates that the EC is used, then this interface should be used for brightness control. Changes in v2: - Use the new shared nvidia-wmi-ec-backlight.h header for the WMI firmware API definitions - ACPI_VIDEO can now be enabled on non X86 too, adjust the Kconfig changes to match this. Changes in v3: - Use WMI_BRIGHTNESS_GUID define Acked-by: Rafael J.

2022-04-25drm/display: Move HDMI helpers into display-helper moduleThomas Zimmermann
Move DRM's HMDI helpers into the display/ subdirectoy and add it to DRM's display helpers. Update all affected drivers. No functional changes. The HDMI helpers were implemented in the EDID and connector code, but are actually unrelated. With the move to the display-helper library, we can remove the dependency on drm_edid.{c,h} in some driver's HDMI source files. Several of the HDMI helpers remain in EDID code because both share parts of their implementation internally. With better refractoring of the EDID code, those HDMI helpers could be moved into the display-helper library as well. v3: * fix Kconfig dependencies (Javier) v2: * reduce HDMI helpers to avoid exporting functions (Jani) * fix include statements (Jani, Javier) * update Kconfig symbols Signed-off-by: Thomas Zimmermann <tzimmermann@suse.de> Reviewed-by: Javier Martinez Canillas <javierm@redhat.com> Link: https://patchwork.freedesktop.org/patch/msgid/20220421073108.19226-8-tzimmermann@suse.de

GSC is a graphics system controller, it provides a chassis controller for graphics discrete cards. There are two MEI interfaces in GSC: HECI1 and HECI2. Both interfaces are on the BAR0 at offsets 0x00258000 and 0x00259000. GSC is a GT Engine (class 4: instance 6). HECI1 interrupt is signaled via bit 15 and HECI2 via bit 14 in the interrupt register.
