This patch does the following: - Fakes live status of HDMI as connected (even if that's not). While testing certain (monitor + cable) combinations with various intel platforms, it seems that live status register doesn't work reliably on some older devices. So limit the live_status check for HDMI detection, only for platforms from gen7 onwards. This fixes regression added by patch: 'commit 237ed86c693d ("drm/i915: Check live status before reading edid")' Based on suggestion by: Ville Syrjala<ville.syrjala@linux.intel.com> Signed-off-by: Shashank Sharma <shashank.sharma@intel.com> --- drivers/gpu/drm/i915/intel_hdmi.c | 6 ++++-- 1 file changed, 4 insertions(+), 2 deletions(-)
