Add an DMA-buf export implementation independent of the DRM helpers. This not only avoids the caching of DMA-buf mappings, but also allows us to use the new dynamic locking approach. This is also a prerequisite of unpinned DMA-buf handling. v2: fix unintended recursion, remove debugging leftovers v3: split out from unpinned DMA-buf work v4: rebase on top of new no_sgt_cache flag v5: fix some warnings by including amdgpu_dma_buf.h v6: fix locking for non amdgpu exports v7: rebased on new DMA-buf locking patch v8: drop extra include Signed-off-by: Christian König <christian.koenig@amd.com> Reviewed-by: Alex Deucher <alexander.deucher@amd.com> Link: https://patchwork.freedesktop.org/patch/337949/
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.
