This series tries to send the vGPU page flip events to userspace, which
can be used by QEMU UI for rendering and display with the latest guest
framebuffers.

v2: Use VFIO irq chain to get eventfds from userspace instead of adding
a new ABI. (Alex)

v1: https://patchwork.kernel.org/cover/10962341/


Tina Zhang (3):
  vfio: Use capability chains to handle device specific irq
  drm/i915/gvt: Leverage irq capability chain to get eventfd
  drm/i915/gvt: Send plane flip events to user space
