Linux kernel source tree

Add CPU caching to properties line in VM snapshot capture indicating the BO caching properites. This is useful information for debug and will help build a robust GPU hang replay tool. The current format is: [<vma address>]: <permissions>|<type>|mem_region=0x%x|pat_index=%d|cpu_caching=%d Permissions has two options, either "read_only" or "read_write". Type has three options, either "userptr", "null_sparse", or "bo". Memory region is a bit mask of where the memory is located. Pat index corresponds to the value setup upon VM bind. CPU caching corresponds to the value of BO setup upon creation. v2: - Save off cpu_caching value rather than looking at BO (Carlos) v4: - Fix NULL ptr dereference (Carlos) Cc: José Roberto de Souza <jose.souza@intel.com> Signed-off-by: Matthew Brost <matthew.brost@intel.com> Reviewed-by: Jonathan Cavitt <jonathan.cavitt@intel.com> Link: https://patch.msgid.link/20251126185952.546277-6-matthew.brost@intel.com |

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.
