This commit introduces a new madvise interface to support driver-specific ioctl operations. The madvise interface allows for more efficient memory management by providing hints to the driver about the expected memory usage and pte update policy for gpuvma. v2 (Matthew/Thomas) - Drop num_ops support - Drop purgeable support - Add kernel-docs - IOWR/IOW v3 (Matthew/Thomas) - Reorder attributes - use __u16 for migration_policy - use __u64 for reserved in unions - Avoid usage of vma Cc: Matthew Brost <matthew.brost@intel.com> Reviewed-by: Matthew Brost <matthew.brost@intel.com> Link: https://lore.kernel.org/r/20250821173104.3030148-2-himal.prasad.ghimiray@intel.com Signed-off-by: Himal Prasad Ghimiray <himal.prasad.ghimiray@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.
