The current PKG_C_LATENCY stuff looks busted in several ways: - doesn't account for multiple pipes from different commits correctly - WM_LINETIME is in units of 0.125usec, PKG_C_LATENCY wants units on 1 usec - weird VRR state stuff being checked - use of pointless RMW Fix it all up. Note that it's still a bit unclear how all this works, especially how the added_wake_time ties into the flipq triggers in DMC, and how we need to sequence updates to PKG_C_LATENCY when enabling/disabling pipes/etc. We may also need to think what to about the WM1+ disabling and the related PSR chicken bits when we can use PKG_C_LATENCY for early wake...

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 reStructuredText 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.
