The DMA mapping can now correspond to a folio (order > 0), so move the iterator by the number of pages in the folio in order to migrate all pages at once. This requires forcing contiguous memory for SVM BOs, which greatly simplifies the code and enables 2MB device page support, allowing a major performance improvement. Negative effects like extra eviction are unlikely as SVM BOs have a maximal size of 2MB. v2: - Improve commit message (Matthew Brost) - Fix increment, chunk, assert match (Matthew Brost) Reviewed-by: Matthew Brost <matthew.brost@intel.com> Link: https://lore.kernel.org/r/20250805140028.599361-7-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.
