uAPI is designed with the use case that only mapping a BO to a malloc'd address will unbind a CPU-address mirror VMA. Therefore, allowing a CPU-address mirror VMA to unbind when the GPU has bindings in the range being unbound does not make much sense. This behavior is not supported, as it simplifies the code. This decision can always be revisited if a use case arises. v3: - s/arrises/arises (Thomas) - s/system allocator/GPU address mirror (Thomas) - Kernel doc (Thomas) - Newline between function defs (Thomas) v5: - Kernel doc (Thomas) v6: - Only compile if CONFIG_DRM_GPUSVM selected (CI, Lucas) Signed-off-by: Matthew Brost <matthew.brost@intel.com> Reviewed-by: Himal Prasad Ghimiray <himal.prasad.ghimiray@intel.com> Reviewed-by: Thomas Hellström <thomas.hellstrom@linux.intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20250306012657.3505757-18-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.
