Subject: [RFC PATCH v2 0/3] Deliver vGPU page flip events to userspace
Date: Tue, 4 Jun 2019 17:55:31 +0800 [thread overview]
Message-ID: <20190604095534.10337-1-tina.zhang@intel.com> (raw)
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
