Subject: [RFC PATCH v2 0/3] Deliver vGPU page flip events to userspace

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
