[Why&How] Temporarily disable SubVP+DRR since Xorg has an architectural limitation where freesync will not work in a multi monitor configuration. SubVP+DRR requires that freesync be working. Whether OS has variable refresh setting enabled or not, the state on the crtc remains same unless an application requests VRR. Due to this, there is no way to know whether freesync will actually work or not while we are on the desktop from the kernel's perspective. If userspace does not have a limitation with multi-display freesync (for example wayland), then this feature can be enabled by adding a dcfeaturemask option to amdgpu on the kernel cmdline like: amdgpu.dcfeaturemask=0x200 Signed-off-by: Aurabindo Pillai <aurabindo.pillai@amd.com> Reviewed-by: Rodrigo Siqueira <Rodrigo.Siqueira@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.
