Subject: [PATCH 0/7] drm/intel: guest i915 changes for Broadwell to run inside VM with Intel GVT-g
Date: Thu, 20 Aug 2015 11:15:13 +0800 [thread overview]
Message-ID: <20150820031513.GA5328@zlv-hp-dev> (raw)
I915 kernel driver can now work inside a virtual machine on Haswell
with Intel GVT-g. In order to do the same thing on Broadwell, there
are some extra changes needed. The two main things are to support the
more complicated PPGTT page table structure and EXECLIST contexts.
GVT-g will perform shadow PPGTT and shadow context, which requires
guest driver to explicitly notify host device model the life cycle of
PPGTT and EXECLIST contexts.
The first and the forth patches added some restrictions to drivers in
virtualization scenario to make the shadow work easier. The first
patch is based on Mika's earlier one, but we use it for vgpu only.
The sixth patch is the implementation of the notification for
shadowing.
Zhiyuan Lv (7):
drm/i915: preallocate pdps for 32 bit vgpu
drm/i915: Enable full ppgtt for vgpu
drm/i915: Always enable execlists on BDW for vgpu
drm/i915: always pin lrc context for vgpu with Intel GVT-g
drm/i915: Update PV INFO page definition for Intel GVT-g
drm/i915: guest i915 notification for Intel-GVTg
drm/i915: Allow Broadwell guest with Intel GVT-g
