[PATCH v2 0/5] drm/xe/display: Transparant fallback from stolen to sysmem.

[Maarten Lankhorst <dev@lankhorst.se>]

Changes since previous version:
- Simplify the patch for copying between sysmem and stolen.
- Take ownership of intel_bo_fbdev_bios_fb_takeover()
- Keep series standalone.

Copy the initial framebuffer from the stolen region to system memory
when deciding to keep the device's framebuffer, instead of re-using the
stolen memory.

This allows for completely flicker-free boot even on platforms where
we wouldn't allow use of stolen memory for the system framebuffer.

Works best with https://patchwork.freedesktop.org/series/170430/	

Maarten Lankhorst (5):
  drm/xe/display: Avoid using stolen memory for framebuffer when media
    gt exists.
  drm/xe/migrate: Support copying between sysmem and stolen
  drm/xe: Raise gt frequency slightly earlier.
  HACK: Always fallback
