[Why] There are some timings for which we support p-state switching in active, but not in blank. There was a previous issue where a timing that had active-only support would hang a p-state request when we were in an extended blanking period. The workaround for that issue was to block active-only p-state switching, but that resulted in a lack of p-state support for some common timings such as 1440p60. We want to fix that issue properly by un-blocking p-state requests while the display is blanked, so that we can re-enable active-only p-state switching. [How] - new version of blank_pixel_data for DCN30 - call hubp->set_blank from dcn30_blank_pixel_data - blank every hubp in the mpcc tree, and odm tree - on blank enable, wait until the next frame before blanking HUBP Signed-off-by: Joshua Aberback <joshua.aberback@amd.com> Reviewed-by: Jun Lei <Jun.Lei@amd.com> Acked-by: Qingqing Zhuo <qingqing.zhuo@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.
