KFD buffer objects do not associate a GEM handle with them so cannot directly be used with libdrm to initiate a system dma (sDMA) operation to speedup the checkpoint and restore operation so export them as dmabuf objects and use with libdrm helper (amdgpu_bo_import) to further process the sdma command submissions. With sDMA, we see huge improvement in checkpoint and restore operations compared to the generic pci based access via host data path.

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 Restructured Text 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.
