Reject interlaced modes on VLV/CHV DP outputs. This simply does not work correctly in the hardware. We do get some output, but it's quite corrupted. The available documentation fails to mention this fact. I contacted some hardware people who eventually managed to locate the relevant HSD for VLV, which was resolved by declaring interlaced DP output as not supported. The HSD was never cloned for CHV even though it inherited most of the hardware and thus has the same problems with interlaced DP output.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. 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.
