It is the expectation of existing userspace (X11 + Mesa, in particular) that jobs submitted to the kernel against a shared BO will get implicitly synchronized by their submission order. If we want to allow clever userspace to disable implicit synchronization, we should do that under its own submit flag (as amdgpu and lima do). Note that we currently only implicitly sync for the rendering pass, not binning -- if you texture-from-pixmap in the binning vertex shader (vertex coordinate generation), you'll miss out on synchronization. Fixes flickering when multiple clients are running in parallel, particularly GL apps and compositors. v2: Fix a missing refcount on the CSD done fence for L2 cleaning.

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.
