This patch adds support to handle automated DP compliance link training test requests. This patch has been tested with Unigraf DPR-120 DP Compliance device for testing Link Training Compliance. After we get a short pulse Compliance test request, test request values are read and hotplug uevent is sent in order to trigger another modeset during which the pipe is configured and link is retrained and enabled for link parameters requested by the test. v5: * Only modify the compliance structure after all validation is done (Jani Nikula) * Remove the variable test_result (Jani Nikula) v4: * Return TEST_NAK for read failures and invalid values (Jani Nikula) * Conver the test link BW to link rate before storing (Jani Nikula) v3: * Validate the test link rate and lane count as soon as the request comes (Jani Nikula) v2: * Validate the test lane count before using it in intel_dp_compute_config (Jani Nikula) Signed-off-by: Manasi Navare <manasi.d.navare@intel.com> Cc: Jani Nikula <jani.nikula@linux.intel.com> Cc: Daniel Vetter <daniel.vetter@intel.com> Cc: Ville Syrjala <ville.syrjala@linux.intel.com> Signed-off-by: Jani Nikula <jani.nikula@intel.com> Link: http://patchwork.freedesktop.org/patch/msgid/1485274594-17361-1-git-send-email-manasi.d.navare@intel.com |

README
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.
