implemented context submission pv optimizaiton within GVTg.
GVTg to read context submission data (elsp_data) from the shared_page
directly without trap cost and eliminate execlist HW behavior emulation
without injecting context switch interrupt to guest under PV
submisison mechanism.

To enable vgpu pv features, we need to setup a shared memory page
which will be used for data exchange directly accessed between both
guest and backend i915 driver to avoid emulation trap cost.
guest i915 will allocate this page memory and then pass it's physical
address to backend i915 driver thr
GVTg implemented shared_page setup operation and read_shared_page
functionality based on hypervisor_read_gpa().
the shared_page_gpa was passed from guest driver through PVINFO
shared_page_gpa register.

v1: rebase.
v2: rebase.
v3: added shared_page_gpa check and if read_gpa failure, retur
To improve vgpu performance, it could implement some PV optimization
such as to reduce the mmio access trap numbers or eliminate certain piece
of HW emulation within guest driver to reduce vm exit/vm enter cost.
the solutions in this patch set are implemented two PV optimizations based
on the shar
This patch extends vgpu ppgtt g2v notification to notify host
GVT-g of ppgtt update from guest including alloc_4lvl, clear_4lv4
and insert_4lvl.
These updates use the shared memory page to pass struct pv_ppgtt_update
from guest to GVT which is used for pv optimiation implemeation within

pv capability for vgpu was introduced by pv_caps in struct
i915_virtual_gpu and a new pv_caps register for host GVT
was defined in struct vgt_if for vgpu pv optimization.

It is performance optimization to override the actual submisison backend

This patch handles ppgtt update from g2v notification.
It read out ppgtt pte entries from guest pte tables page and
convert them to host pfns.
It creates local ppgtt tables and insert the content pages
into the local ppgtt tables directly, which does not track

Hi all,
Trying to fetch the drm-intel-fixes tree today gives me this error:
-
fatal: Could not read from remote repository.
Please make sure you have the correct access rights

This is still broken in v5.2-rc3.

i915_gem_gtt_info has been removed and so flink-and-exit-vma-leak is
defunct.
