Linux kernel source tree
2cd9a689e9
The device global init_power_on flag is somewhat arbitrary and makes debugging power refcounting problems difficult. Instead arrange things so that all display power domain get has a corresponding put call. After this change we have the following sequences: driver loading: intel_power_domains_init_hw(); <other init steps> intel_power_domains_enable(); driver unloading: intel_power_domains_disable(); <other uninit steps> intel_power_domains_fini_hw(); system suspend: intel_power_domains_disable(); <other suspend steps> intel_power_domains_suspend(); system resume: intel_power_domains_resume(); <other resume steps> intel_power_domains_enable(); at other times while the driver is loaded: intel_display_power_get(); ... intel_display_power_put(); Suggested-by: Chris Wilson <chris@chris-wilson.co.uk> Cc: Chris Wilson <chris@chris-wilson.co.uk> Signed-off-by: Imre Deak <imre.deak@intel.com> Reviewed-by: Chris Wilson <chris@chris-wilson.co.uk> Link: https://patchwork.freedesktop.org/patch/msgid/20180816123757.3286-2-imre.deak@intel.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.
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.
