This struct embeds more information than just the DMA address. This will help later to support folio orders greater than zero. At this point, there is no functional change as the only struct member used is addr. In Xe, adapt to the new drm_gpusvm_devmem_ops type signatures using struct drm_pagemap_addr, as well as the internal xe SVM functions implementing those operations. The use of this struct is propagated to xe_migrate as it makes indexed accesses to the next DMA address but they are no longer contiguous. v2: - Rename drm_pagemap_device_addr to drm_pagemap_addr (Matthew Brost) - Squash with patch for Xe (Matthew Brost) - Set proto and dir for completeness (Matthew Brost) - Assess DMA map protocol (Matthew Brost) Cc: Matthew Brost <matthew.brost@intel.com> Reviewed-by: Matthew Brost <matthew.brost@intel.com> Acked-by: Maarten Lankhorst <maarten.lankhorst@linux.intel.com> Link: https://lore.kernel.org/r/20250805140028.599361-3-francois.dugast@intel.com Signed-off-by: Francois Dugast <francois.dugast@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.
