Lockdep is unhappy about ggtt->lock -> runtime_pm, where it seems to think this can somehow get inverted. The ggtt->lock looks like a potentially sensitive driver lock, so likely a sensible move to never call the runtime_pm routines while holding it. Actually it looks like d3cold wants to grab this, so perhaps this can indeed deadlock. v2: - Don't forget about xe_gt_tlb_invalidation_vma(), which now needs explicit access_get.

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.
