drm/xe: move DPT l2 flush to a more sensible place

commit f16873f42a06b620669d48a4b5c3f888cb3653a1 upstream. Only need the flush for DPT host updates here. Normal GGTT updates don't need special flush.

drm/{i915,xe}: Run DRM default client setup

2025-03-05T20:48:50Z

Rework fbdev probing to support fbdev_probe in struct drm_driver and remove the old fb_probe callback. Provide an initializer macro that sets the callback in struct drm_driver according to the kernel configuration. Call drm_client_setup_with_color_mode() to run the kernel's default client setup for DRM. This commit also prepares support for the kernel's drm_log client (or any future client) in i915. Using drm_log will also require vmap support in GEM objects.

drm/{i915, xe}: Suspend/resume fbdev emulation via client interfaces

2025-03-05T20:48:49Z

Implement drm_client_dev_suspend() and drm_client_dev_resume() for i915's fbdev emulation and call the helper via DRM client interfaces. This is required to convert i915 and xe to DRM's generic fbdev client. No functional changes.

drm/xe/display: Fix fbdev GGTT mapping handling.

2025-03-05T20:48:49Z

FBDEV ggtt is not restored correctly, add missing GGTT flag to intel_fbdev_fb_alloc to make it work. This ensures that the global GGTT mapping is always restored on resume. The GGTT mapping would otherwise be created in intel_fb_pin_to_ggtt() by intel_fbdev anyway. This fixes the fbdev device not working after resume.

drm/i915: relocate intel_plane_ggtt_offset() to intel_atomic_plane.c

2025-03-03T11:44:42Z

With the primary goal of removing #include "i915_vma.h" from intel_display_types.h, move intel_plane_ggtt_offset() to a proper function in intel_atomic_plane.c. This reveals tons of implicit dependencies all over the place that we pulled in via i915_vma.h. Fix the fallout.
