Linux kernel source tree
e0aee99015
Instead of injecting extra crtc commits to serialize the global state let's hand roll a bit of commit machinery to take care of the hardware synchronization. Rather than basing everything on the crtc commits we track these as their own thing. I think this makes more sense as the hardware blocks we are working with are not in any way tied to the pipes, so the completion should not be tied in with the vblank machinery either. The difference to the old behaviour is that: - we no longer pull extra crtcs into the commit which should make drm_atomic_check_only() happier - since those crtcs don't get pulled in we also don't end up reprogamming them and thus don't need to wait their vblanks to pass/etc. So this should be tad faster as well. TODO: perhaps have each global object complete its own commit once the post-plane update phase is done?

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.
