[Description] - For FPO + Vactive cases, we rely on the Vactive display to be at it's nominal refresh rate because the Vactive pipe may not necessarily assert P-State allow while it's in VBLANK - For cases where the Vactive display has a stretched VBLANK due to VRR, we could underflow when trying to complete an FPO + Vactive MCLK switch because the FPO display has limited VBLANK time in waiting for the Vactive display to assert P-State allow naturally - Block FPO + Vactive if the Vactive display has VRR active (variable or fixed) Reviewed-by: Jun Lei <Jun.Lei@amd.com> Acked-by: Alex Hung <alex.hung@amd.com> Signed-off-by: Alvin Lee <Alvin.Lee2@amd.com> Tested-by: Daniel Wheeler <daniel.wheeler@amd.com> Signed-off-by: Alex Deucher <alexander.deucher@amd.com>
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.
