Linux kernel source tree
e9d8e02748
Each V3D queue works independently and all the dependencies between the jobs are handled through the DRM scheduler. Therefore, there is no need to use one single lock for all queues. Using it, creates unnecessary contention between different queues that can operate independently. Replace the global spinlock with per-queue locks to improve parallelism and reduce contention between different V3D queues (BIN, RENDER, TFU, CSD). This allows independent queues to operate concurrently while maintaining proper synchronization within each queue.

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.
