While DG2 supports DC5 and DC9, some of the tests in fast-feedback blew up DG2 when the tests forced transition from dc5->dc9 on suspend and dc9->dc5 on resume. Some local experiments performed with Rodrigo on a RIL system showed promising results when dc5 was completely diabled and i915 took only dc9 paths. Sending this so we can check the CI results to confirm the findings from local testing which will hopefully help narrow down the root cause of MMIO BAR lost issue Cc: Rodrigo Vivi <rodrigo.vivi@xxxxxxxxx> Cc: Imre Deak <imre.deak@xxxxxxxxx> Anusha Srivatsa (1): drm/i915/dmc: Load DMC on DG2 drivers/gpu/drm/i915/display/intel_display_power.c | 4 +++- drivers/gpu/drm/i915/display/intel_dmc.c | 10 +++++++++- 2 files changed, 12 insertions(+), 2 deletions(-) -- 2.25.1
