The global list of all debugfs entries for the driver was painful: the list couldn't see into the components' structs, so each component had its own debugs show function to find the component, then find the regset and dump it. The components also had to be careful to check that they were actually registered in vc4 before dereferencing themselves, in case they weren't probed on a particular platform. They routinely failed at that. Instead, we can have the components add their debugfs callbacks to a little list in vc4 to be registered at drm_dev_register() time, which gets vc4_debugfs.c out of the business of knowing the whole list of components. Thanks to this change, dsi0 (if it existed) would register its node. v2: Rebase on hvs_underrun addition. v3: whitespace fixup Signed-off-by: Eric Anholt <eric@anholt.net> Link: https://patchwork.freedesktop.org/patch/msgid/20190401183559.3823-1-eric@anholt.net Reviewed-by: Paul Kocialkowski <paul.kocialkowski@bootlin.com> |

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.
