Right now, we make the mistake of allowing interlacing on all connectors. Nvidia hardware does not always support interlacing with DP though, so we need to make sure that we don't allow interlaced modes to be set in such situations as otherwise we'll end up accidentally hanging the display HW. This fixes some hangs with Turing, which would be caused by attempting to set an interlaced mode on hardware that doesn't support it. This patch likely fixes other hardware hanging in the same way as well. Note that we say we probe PIOR caps, but they don't actually have any interlacing caps. So, the get_caps() function for PIORs just sets interlacing support to true. Changes since v1: * Actually probe caps correctly this time, both on EVO and NVDisplay. Changes since v2: * Fix probing for < GF119 * Use vfunc table, in prep for adding more caps in the future. Signed-off-by: Lyude Paul <lyude@redhat.com> Signed-off-by: Ben Skeggs <bskeggs@redhat.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.
