Page reclamation feature needs the PRL to be suballocated into a GGTT-mapped BO. On allocation failure, fallback to default tlb invalidation with full PPC flush. PRL's BO allocation is managed in separate pool to ensure 4K alignment for proper GGTT address. With BO, pass into TLB invalidation backend and modify fence to accomadate accordingly. v2: - Removed page reclaim related variables from TLB fence. (Matthew B) - Allocate PRL bo size to num_entries. (Matthew B) - Move PRL bo allocation to tlb_inval run_job. (Matthew B) v5: - Use xe_page_reclaim_list_valid.

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.
