Introduce xe_vm_find_cpu_addr_mirror_vma_range(), which computes an extended range around a given range by including adjacent VMAs that are CPU-address-mirrored and have default memory attributes. This helper is useful for determining mergeable range without performing the actual merge. v2 - Add assert - Move unmap check to this patch v3 - Decrease offset to check by SZ_4K to avoid wrong vma return in fast lookup path v4 - *start should be >= SZ_4K (Matt) Cc: Matthew Brost <matthew.brost@intel.com> Cc: Thomas Hellström <thomas.hellstrom@linux.intel.com> Reviewed-by: Matthew Brost <matthew.brost@intel.com> Link: https://patch.msgid.link/20251125075628.1182481-2-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.
