13 daysmei: lb: add late binding version 2Alexander Usyskin
The second Late Binding version allows to send payload bigger than client MTU by splitting it to chunks and uses separate firmware client for transfer. The component interface is unchanged and driver doing all splitting. Only one Late Binding version is supported by firmware. When Late binding version 2 is supported, the new client is advertised by firmware and existing MKHI will have version 2. This helps driver to select the right mode of work.

2026-03-24drm/xe/pf: Add FLR_PREPARE state to VF control flowPiotr Piórkowski
Our xe-vfio-pci component relies on the confirmation from the PF that VF FLR processing has finished, but due to the notification latency on the HW/FW side, PF might be unaware yet of the already triggered VF FLR. Update VF state machine with new FLR_PREPARE state that indicate imminent VF FLR notification and treat that as a begin of the FLR sequence.

Add .framebuffer_init, .framebuffer_fini and .framebuffer_lookup to the bo parent interface. While they're about framebuffers, they're specifically about framebuffer objects, so the bo interface is a good enough fit, and there's no need to add another interface struct.

2026-03-16drm/{i915, xe}/bo: move display bo calls to parent interfaceJani Nikula
Continue i915 and xe separation from display by moving the bo calls to the display parent interface. Instead of adding all these functions to intel_parent.[ch], reuse the now vacated intel_bo.[ch], and avoid mass renames to calls of these functions. This is similar to intel_display_rpm.[ch]. Make many of the hooks optional to avoid having to implement dummy functions in xe. Indeed now we can remove many of the existing dummy functions.

For xe, add new file xe_frontbuffer.c for the same. Note: The intel_frontbuffer_flush() calls from i915_gem_object_frontbuffer.c will partially route back to i915 core via the parent interface.

2026-02-26drm/i915/dpt: pass opaque struct intel_dpt around instead of i915_address_spaceJani Nikula
struct i915_address_space is used in an opaque fashion in the display parent interface, but it's just one include away from being non-opaque. And anyway the name is rather specific. Switch to using the struct intel_dpt instead, which embeds struct i915_address_space anyway. With the definition hidden in i915_dpt.c, this can't be accidentally made non-opaque, and the type seems rather more generic anyway. We do have to add a new helper i915_dpt_to_vm(), as there's one case in intel_fb_pin_to_dpt() that requires direct access to struct i915_address_space. But this just underlines the point about opacity.

2025-12-11drm/i915/display: Detect AuxCCS support via display parent interfaceTvrtko Ursulin
Whether AuxCCS can be properly supported depends on the support both from the display side and non-display side of the driver. Let us therefore allow for the non-display part to be queried via the display parent interface. The new interface replaces the HAS_AUX_CCS macro and we also remove the FIXME from skl_universal_plane_create since now the xe will not advertise the AuxCCS caps to start with so they do not need to be removed after enumeration. Also, by removing this build specific FIXME we come a step closer to fully de-coupling display and non-display. The existing HAS_AUX_CCS gets renamed to HAS_AUX_DIST since it is still required for determining the need for PLANE_AUX_DIST programming.
