If there are no changes to intel_crtc_can_enable_sagv() there is no need to do all the sagv bw_state recomputation. The only slight caveat here is hw state takeover where we initially disable SAGV, and want it to get re-enabled once we've determined that it's safe to do so. That can now be achieved by having intel_crtc_can_enable_sagv() reject SAGV as long as the crtc_state->inherited flag is set. Once the flag gets cleared (during initial commit for inactive pipes, during the first userspace commit for active pipes), we will naturally recompute all the sagv related state.

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.
