svm_bo eviction mechanism is different from regular BOs. Every SVM_BO created contains one eviction fence and one worker item for eviction process. SVM_BOs can be attached to one or more pranges. For SVM_BO eviction mechanism, TTM will start to call enable_signal callback for every SVM_BO until VRAM space is available. Here, all the ttm_evict calls are synchronous, this guarantees that each eviction has completed and the fence has signaled before it returns.

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.
