BugLink: https://bugs.launchpad.net/bugs/2031057 [Impact] screen flickering when the setup is in multiple monitors with mirror mode output [Fix] remove the support of interlaced mode in intel graphic driver for dp and hdmi. [Test] 1. compile test 2. check the test kernel on the intel platform to prevent any regression. 3. customer verified the patch fixed the issue on their hardware. [Where problems could occur] the regression would happen when the monitor supports only interlaced mode, but the case should be very rare nowaday. ---------------------------------------------------------------- Ankit Nautiyal (1): UBUNTU: SAUCE: (no-up) drm/i915/display : Remove support for interlace mode drivers/gpu/drm/i915/display/intel_dp.c | 2 -- drivers/gpu/drm/i915/display/intel_hdmi.c | 3 --- 2 files changed, 5 deletions(-)
