Add more SVM GT stats which give visibility to where time is spent in the SVM page fault handler. Stats include number of faults at a given size, total SVM page fault time, migration time in us, copy time in us, copy kb, get pages time in us, and bind time in us. Will help in tuning SVM for performance. v2: - Include local changes v3: - Add tlb invalidation + valid page fault + per size copy size stats v4: - Ensure gt not NULL when incrementing SVM copy stats - Normalize stats names - Use magic macros to generate increment functions for ranges v7: - Use DEF_STAT_STR (Michal) Signed-off-by: Matthew Brost <matthew.brost@intel.com> Reviewed-by: Francois Dugast <francois.dugast@intel.com> Link: https://lore.kernel.org/r/20250829172232.1308004-3-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.
