[Why] The registers for the address of the cursor are aligned to 2KB, so all cursor surfaces also need to be aligned to 2KB. Currently, the provided cursor cache surface is not aligned, so we need a workaround until alignment is enforced by the surface provider. [How] - round up surface address to nearest multiple of 2048 - current policy is to provide a much bigger cache size than necessary,so this operation is safe Tested-by: Daniel Wheeler <daniel.wheeler@amd.com> Signed-off-by: Joshua Aberback <joshua.aberback@amd.com> Reviewed-by: Jun Lei <Jun.Lei@amd.com> Acked-by: Eryk Brol <eryk.brol@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.
