For each rebind we insert a GuC TLB invalidation and add a corresponding unordered TLB invalidation fence. This might add a huge number of TLB invalidation fences to wait for so rather than doing that, defer the TLB invalidation to the next ring ops for each affected exec queue. Since the TLB is invalidated on exec_queue switch, we need to invalidate once for each affected exec_queue. v2: - Simplify if-statements around the tlb_flush_seqno. (Matthew Brost) - Add some comments and asserts. Fixes: |

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the reStructuredText markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
