The vblank and nonstall events have some annoying interactions with DRM locking, and aren't able to do certain things as a result. However, other uses of event notifications don't have such requirements, and upcoming patches take advantage of this for various improvements. Having separate classes for each nvkm_event's spinlocks allows lockdep to distinguish between them and avoid false-positives. v2: __always_inline + comment Signed-off-by: Ben Skeggs <bskeggs@redhat.com> Reviewed-by: Lyude Paul <lyude@redhat.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.
