Andrzej Pietrasiewicz 49d29a077a drm: vc4: adapt to new behaviour of drm_crtc.c When drm_crtc_init_with_planes() was orignally added (in drm_crtc.c, `e13161af80` drm: Add drm_crtc_init_with_planes() (v2)), it only checked for "primary" being non-null. If that was the case, it modified primary->possible_crtcs. Then, when support for cursor planes was added (`fc1d3e44ef` drm: Allow drivers to register cursor planes with crtc), the same behaviour was implemented for cursor planes. vc4_plane_init() since its inception has passed 0xff as "possible_crtcs" parameter to drm_universal_plane_init(). With a change in drm_crtc.c (`7abc7d4751` drm: don't override possible_crtcs for primary/cursor planes) passing 0xff results in primary's possible_crtcs set to 0xff (cursor was updated manually by vc4_crtc.c). Consequently, it would be allowed to use the primary plane from CRTC 1 (for example) on CRTC 0, which would result in the overlay and cursors being buried.

README

Linux kernel
============

This file was moved to Documentation/admin-guide/README.rst

Please notice that there are several guides for kernel developers and users.
These guides can be rendered in a number of formats, like HTML and PDF.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.

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.
