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.

Merge tag 'topic/mst-suspend-resume-reprobe-2019-10-29-2' of git://anongit.freedesktop.org/drm/drm-misc into drm-next UAPI Changes: Cross-subsystem Changes: Core Changes: * Handle UP requests asynchronously in the DP MST helpers, fixing hotplug notifications and allowing us to implement suspend/resume reprobing * Add basic suspend/resume reprobing to the DP MST helpers * Improve locking for link address reprobing and connection status request handling in the DP MST helpers * Miscellaneous refactoring in the DP MST helpers * Add a Kconfig option to the DP MST helpers to enable tracking of gets/puts for topology references for debugging purposes Driver Changes: * nouveau: Resume hotplug interrupts earlier, so that sideband messages may be transmitted during resume and thus allow suspend/resume reprobing for DP MST to work * nouveau: Avoid grabbing runtime PM references when handling short DP pulses, so that handling sideband messages in resume codepaths with the DP MST helpers doesn't deadlock us * i915, nouveau, amdgpu, radeon: Use detect_ctx for probing MST connectors, so that we can grab the topology manager's atomic lock Note: there's some amdgpu patches that I didn't realize were pushed upstream already when creating this topic branch. When they fail to apply, you can just ignore and skip them.
