Glitches deasserting the connector HPD line can lead to incorrectly detecting a disconnect event (a glitch asserting the line will only cause a redundant connect->disconnect transition). The source of such a glitch can be noise on the line or a 0.5ms-1ms MST IRQ_HPD pulse. TypeC ports in the DP-alt or TBT-alt mode filter out these glitches inernally, but for others the driver has to do this. Make it so by polling the HPD line on these connectors for 4 ms.

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.
