It looks like this code was accidentally dropped at some point(in a slightly different form), so add it back. The gist is that if we know the allocation will be one single chunk, then we can just annotate the BO with I915_BO_ALLOC_CONTIGUOUS, even if the user doesn't bother. In the future this should allow us to avoid using vmap for such objects, in some upcoming patches. v2(Thomas): - Tweak the commit message to mention the future motivation Signed-off-by: Matthew Auld <matthew.auld@intel.com> Cc: Thomas Hellström <thomas.hellstrom@linux.intel.com> Reviewed-by: Thomas Hellström <thomas.hellstrom@linux.intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20220202173154.3758970-1-matthew.auld@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 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.
