mainlining shenanigans
b3d91800d9
When there are back to back commits with async cursor update, there is a case where second commit can program the DPU hw blocks while first didn't complete flushing config to HW. Synchronize the compositions such that second commit waits until first commit flushes the composition. This change also introduces per crtc commit lock, such that commits on different crtcs are not blocked by each other. Changes in v2: - Use an array of mutexes in kms to handle commit lock per crtc. (Rob Clark) Changes in v3: - Add wrapper functions to handle lock and unlock of commit_lock for each crtc.

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.
