Linux kernel source tree
91bd7a441b
There are some corner cases wrt underrun when we enable FBC with PSR2 on TGL. Recommendation from hardware is to keep this combination disabled. Bspec: 50422 HSD: 14010260002 v2: Added psr2 enabled check from crtc_state (Anshuman) Added Bspec link and HSD referneces (Jose) v3: Moved the logic to disable fbc to intel_fbc_update_state_cache and removed the crtc->config usages, as per Ville's recommendation. v4: Introduced a variable in fbc state_cache instead of the earlier plane.visible WA, as suggested by Jose. v5: Dropped an extra check for fbc in intel_fbc_enable and addressed review comments by Jose. v6: Move WA to end of function and added Jose's RB.

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.
