Merge tag 'drm-intel-next-2024-11-04' of https://gitlab.freedesktop.org/drm/i915/kernel into drm-next

drm/i915 feature pull #2 for v6.13:

Features and functionality:

- Pantherlake (PTL) Xe3 LPD display enabling for xe driver (Clint, Suraj,
  Dnyaneshwar, Matt, Gustavo, Radhakrishna, Chaitanya, Haridhar, Juha-Pekka, Ravi)
- Enable dbuf overlap detection on Lunarlake and later (Stanislav, Vinod)
- Allow fastset for HDR infoframe changes (Chaitanya)
- Write DP source OUI also for non-eDP sinks (Imre)

Refactoring and cleanups:
- Independent platform identification for display (Jani)
- Display tracepoint fixes and cleanups (Gustavo)
- Share PCI ID headers between i915 and xe drivers (Jani)
- Use x100 version for full version and release checks (Jani)
- Conversions to struct intel_display (Jani, Ville)
- Reuse DP DPCD and AUX macros in gvt instead of duplication (Jani)
- Use string choice helpers (R Sundar, Sai Teja)
- Remove unused underrun detection irq code (Sai Teja)
- Color management debug improvements and other cleanups (Ville)
- Refactor panel fitter code to a separate file (Ville)
- Use try_cmpxchg() instead of open-coding (Uros Bizjak)

Fixes:
- PSR and Panel Replay fixes and workarounds (Jouni)
- Fix panel power during connector detection (Imre)
- Fix connector detection and modeset races (Imre)
- Fix C20 PHY TX MISC configuration (Gustavo)
- Improve panel fitter validity checks (Ville)
- Fix eDP short HPD interrupt handling while runtime suspended (Imre)
- Propagate DP MST DSC BW overhead/slice calculation errors (Imre)
- Stop hotplug polling for eDP connectors (Imre)
- Workaround panels reporting bad link status after PSR enable (Jouni)
- Panel Replay VRR VSC SDP related workaround and refactor (Animesh, Mitul)
- Fix memory leak on eDP init error path (Shuicheng)
- Fix GVT KVMGT Kconfig dependencies (Arnd Bergmann)
- Fix irq function documentation build warning (Rodrigo)
- Add platform check to power management fuse bit read (Clint)
- Revert kstrdup_const() and kfree_const() usage for clarity (Christophe JAILLET)
- Workaround horizontal odd panning issues in display versions 20 and 30 (Nemesa)
- Fix xe drive HDCP GSC firmware check (Suraj)

Merges:
- Backmerge drm-next to get some KVM changes (Rodrigo)
- Fix a build failure originating from previous backmerge (Jani)
