Rather than relying on the TTM watermark accounting add a shrinker for xe_bos in TT or system memory. Leverage the newly added TTM per-page shrinking and shmem backup support. Although xe doesn't fully support WONTNEED (purgeable) bos yet, introduce and add shrinker support for purgeable ttm_tts. v2: - Cleanups bugfixes and a KUNIT shrinker test. - Add writeback support, and activate if kswapd. v3: - Move the try_shrink() helper to core TTM. - Minor cleanups. v4: - Add runtime pm for the shrinker. Shrinking may require an active device for CCS metadata copying. v5: - Separately purge ghost- and zombie objects in the shrinker. - Fix a format specifier - type inconsistency. (Kernel test robot). v7: - s/long/s64/ (Christian König) - s/sofar/progress/ (Matt Brost) v8: - Rebase on Xe KUNIT update. - Add content verifying to the shrinker kunit test. - Split out TTM changes to a separate patch. - Get rid of multiple bool arguments for clarity (Matt Brost) - Avoid an error pointer dereference (Matt Brost) - Avoid an integer overflow (Matt Auld) - Address misc review comments by Matt Brost. v9: - Fix a compliation error. - Rebase. v10: - Update to new LRU walk interface. - Rework ghost-, zombie and purged object shrinking. - Rebase. v11: - Use additional TTM helpers. - Honor __GFP_FS and __GFP_IO - Rebase. v13: - Use ttm_tt_setup_backup(). v14: - Don't set up backup on imported bos. v15: - Rebase on backup interface changes.

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.
