From: "You-Sheng Yang (vicamo)" <vicamo.yang@canonical.com> BugLink: https://bugs.launchpad.net/bugs/1991974 [Impact] AMD Yellow Carp system hang on HDMI plug in/out over dock station. [Fix] 5 patches from mainline kernel v5.16 to be backported. [Test Case] Plug and unplug HDMI cable connected external monitor on a docking station connected to HP Lockheed platform to try trigger system hang. [Where problems could occur] This series tries to address null state of MST link encoder, and no know fix commits for them ever since till current mainline HEAD. [Other Info] While this is already available in v5.16 kernel and on, only 5.15 and oem-5.14 are nominated for fix. Jimmy Kizito (2): drm/amd/display: Fix MST link encoder availability check. drm/amd/display: Add work around for tunneled MST. Meenakshikumar Somasundaram (3): drm/amd/display: Fix for link encoder access for MST. drm/amd/display: FEC configuration for dpia links drm/amd/display: FEC configuration for dpia links in MST mode drivers/gpu/drm/amd/display/dc/core/dc_link.c | 34 +++++++++++++++++-- .../drm/amd/display/dc/core/dc_link_enc_cfg.c | 23 ++++++++++--- .../gpu/drm/amd/display/dc/core/dc_resource.c | 20 +++++------ drivers/gpu/drm/amd/display/dc/dc.h | 3 +- drivers/gpu/drm/amd/display/dc/dc_link.h | 2 ++ .../display/dc/dcn31/dcn31_dio_link_encoder.c | 4 +-- 6 files changed, 66 insertions(+), 20 deletions(-)
