Add SVM device memory mirroring which enables device pages for migration. Enabled via CONFIG_XE_DEVMEM_MIRROR Kconfig. Kconfig option defaults to enabled. If not enabled, SVM will work sans migration and KMD memory footprint will be less. v3: - Add CONFIG_XE_DEVMEM_MIRROR v4: - Fix Kconfig (Himal) - Use %pe to print errors (Thomas) - Fix alignment issue (Checkpatch) v5: - s/xe_mem_region/xe_vram_region (Rebase) v6: - Only compile if CONFIG_DRM_GPUSVM selected (CI, Lucas) - s/drm_info/drm_dbg/ Signed-off-by: Niranjana Vishwanathapura <niranjana.vishwanathapura@intel.com> Signed-off-by: Oak Zeng <oak.zeng@intel.com> Signed-off-by: Matthew Brost <matthew.brost@intel.com> Reviewed-by: Thomas Hellström <thomas.hellstrom@linux.intel.com> Reviewed-by: Himal Prasad Ghimiray <himal.prasad.ghimiray@intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20250306012657.3505757-22-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.
