When TTM failed to alloc VRAM, TTM try evict BOs from VRAM to system memory then retry the allocation, this skips the KFD BOs from the same process because KFD require all BOs are resident for user queues. If TTM with TTM_PL_FLAG_CONTIGUOUS flag to alloc contiguous VRAM, allow TTM evict KFD BOs from the same process, this will evict the user queues first, and restore the queues later after contiguous VRAM allocation.

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.
