[RFCv2 PATCH 00/14] gvt: Hacking i915 for GVT context requirement

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



This patchset is used to discuss and finalize the i915 changes required by
GVT context. Previously we have discussed about how to hack i915 to meet
GVT context requirement, and thanks for the idea and comments.

In this patchset, mostly it refactors the existing i915 APIs, spliting the
hard-coded assumptions from its core logic, keep these assumptions in the
high level wrapper and make the core logic much more flexible and config-
urable, which is able to be used by GVT context creation and submission.

Mostly it based on Daniel's and Kevin's idea here:

http://www.spinics.net/lists/intel-gfx/msg87745.html

And also it incldues the two v2 patches which have addresses the comments
from Joonas

drm/i915: Introduce host graphics memory/fence partition for GVT-g

Acknowledgment
---------------

iGVT-g implementation is several years effort and many people
contributed to the code. There names are not here yet. In later formal
patchset we will reflect individual's contribution.

Meanwhile, in the previous iGVT-g related discussion, Daniel, Chris
and Joonas ever gave very good inputs. We appreciate them and look
forward to more comments/suggestions from community.

We are trying to get more familiar with i915 and willing to adopt
suggestions to keep improving. We hope to work with community together
to make iGVT-g a great component in i915 to support graphics 
virtualization. Thanks!
