BugLink: http://bugs.launchpad.net/bugs/1731091 To fix this bug, I filed a bugzilla bug to upstream: https://bugzilla.kernel.org/show_bug.cgi?id=197785 And in the comment 8 of this bugzilla bug, one Intel engineer suggested to apply these 3 patches, the patch 1/3 and 2/3 was already accepted by upstream maintainer and is going to be merged to the mainline kernel, the patch 3/3 is in discussion. We applied these 3 patches both to linux-4.14-rc8 and artful kernel, they all worked well (HDMI audio worked well and graphic worked as before). Since the OEM project is waiting for these patches, we need to merge this patch to oem kernel first. Abhay Kumar (1): UBUNTU: SAUCE: drm/i915: set minimum CD clock to twice the BCLK. Ville Syrjälä (2): UBUNTU: SAUCE: drm/i915: Track minimum acceptable cdclk instead of "minimum dotclock" UBUNTU: SAUCE: drm/i915: Consolidate max_cdclk_freq check in intel_crtc_compute_min_cdclk() drivers/gpu/drm/i915/i915_drv.h | 12 +- drivers/gpu/drm/i915/intel_cdclk.c | 272 +++++++++++++++++------------------ drivers/gpu/drm/i915/intel_display.c | 24 ++-- drivers/gpu/drm/i915/intel_drv.h | 4 +- 4 files changed, 159 insertions(+), 153 deletions(-)
