Imre Deak 6dfc4a8f13 drm/i915: Verify power domains after enabling them After commit `2cd9a689e9` ("drm/i915: Refactor intel_display_set_init_power() logic") it makes more sense to check the power domain/well refcounts after enabling the power domains functionality. Before that it's guaranteed that most power wells (in the INIT domain) will have a reference held, so not an interesting state. While at it also add the check after the init_hw/fini_hw, disable and suspend/resume steps. Make the test optional on a Kconfig option since it may add substantial overhead: on VLV/CHV the corresponding PUNIT reg access for each power well may take up to 20ms. v2: - Add the state check to more spots. (Chris) v3: - During suspend check the state before deiniting display core. Afterwards DC states are disabled (and so the dc_off power well is enabled) even though we don't hold a reference on it. - Do the test conditionally based on a new Kconfig option.

README

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.
