Add the skeleton framework for supporting automation for Displayport compliance testing. This patch adds the necessary framework for the source device to appropriately respond to test automation requests from a sink device. V2: - Addressed previous mailing list feedback - Fixed compilation issue (struct members declared in a later patch) - Updated debug messages to be more accurate - Added status checks for the DPCD read/write calls - Removed excess comments and debug messages - Fixed debug message compilation warnings - Fixed compilation issue with missing variables - Updated link training autotest to ACK V3: - Fixed the checks on the DPCD return code to be <= 0 rather than != 0 - Removed extraneous assignment of a NAK return code in the DPCD read failure case - Changed the return in the DPCD read failure case to a goto to the exit point where the status code is written to the sink - Removed FAUX test case since it's deprecated now - Removed the compliance flag assignment in handle_test_request V4: - Moved declaration of type_type here - Removed declaration of test_data (moved to a later patch) - Added reset to 0 for compliance test variables V5: - Moved test_active variable declaration and initialization out of this patch and into the patch where it's used - Changed variable name compliance_testing_active to compliance_test_active to unify the naming convention - Added initialization for compliance_test_type variable Signed-off-by: Todd Previte <tprevite@gmail.com> Reviewed-by: Paulo Zanoni <paulo.r.zanoni@intel.com> Signed-off-by: Daniel Vetter <daniel.vetter@ffwll.ch> |
