The VC4 needs more memory than the default setting (16 MB):
vc4-drm soc:gpu: swiotlb: coherent allocation failed, size=16777216
[drm:vc4_bo_create [vc4]] *ERROR* Failed to allocate from CMA:
vc4_v3d 3fc00000.v3d: Failed to allocate memory for tile binning: -12.
You may need to enable CMA or give it more memory.
vc4-drm soc:gpu: failed to bind 3fc00000.v3d (ops vc4_v3d_ops [vc4]): -12
vc4-drm soc:gpu: master bind failed: -12
vc4-drm: probe of soc:gpu failed with error -12
So increase the value to 32 MB and fix this issue.

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.
See Documentation/00-INDEX for a list of what is contained in each file.
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.
