For the -reporter this means that the display will always run at 40Hz which is -quite annoying. This may be due to the mode comparison. - -But there are some other potential issues. The choice of alt_fixed_mode -seems dubious. It's the first non-preferred mode, but there are no -guarantees that the only difference would be refresh rate. Similarly, -there may be more than one preferred mode in the probed modes list, and -the commit changes the preferred mode selection to choose the last one -on the list instead of the first. - -(Note that the probed modes list is the raw, unfiltered, unsorted list -of modes from drm_add_edid_modes(), not the pretty result after a -drm_helper_probe_single_connector_modes() call.) - -Finally, we already have eerily similar code in place to find the -downclock mode for DRRS that seems like could be reused here. - -Back to the drawing board. - -Note: This is a hand-crafted revert due to conflicts. If it fails to -backport, please just try reverting the original commit directly. - -Bugzilla: https://bugs.freedesktop.org/show_bug.cgi?id=105469 -Reported-by: Rune Petersen <rune@megahurts.dk> -Reported-by: Mark Spencer <n7u4722r35@ynzlx.anonbox.net> -Fixes: dc911f5bd8aa ("drm/i915/edp: Allow alternate fixed mode for eDP if available.") -Cc: Clint Taylor <clinton.a.taylor@intel.com> -Cc: David Weinehall <david.weinehall@linux.intel.com> -Cc: Rodrigo Vivi <rodrigo.vivi@intel.com> -Cc: Paulo Zanoni <paulo.r.zanoni@intel.com> -Cc: Jani Nikula <jani.nikula@intel.com> -Cc: Chris Wilson <chris@chris-wilson.co.uk> -Cc: Jim Bride <jim.bride@linux.intel.com> -Cc: Jani Nikula <jani.nikula@linux.intel.com> -Cc: Joonas Lahtinen <joonas.lahtinen@linux.intel.com> -Cc: intel-gfx@lists.freedesktop.org -Cc: <stable@vger.kernel.org> # v4.14+ -Signed-off-by: Jani Nikula <jani.nikula@intel.com> -Reviewed-by: Dhinakaran Pandiyan <dhinakaran.pandiyan@intel.com> -Link: https://patchwork.freedesktop.org/patch/msgid/20180516080110.22770-1-jani.nikula@intel.com ---- - drivers/gpu/drm/i915/intel_dp.c | 38 ++++-------------------------- - drivers/gpu/drm/i915/intel_drv.h | 2 -- - drivers/gpu/drm/i915/intel_dsi.c | 2 +- - drivers/gpu/drm/i915/intel_dvo.c | 2 +- - drivers/gpu/drm/i915/intel_lvds.c | 3 +-- - drivers/gpu/drm/i915/intel_panel.c | 6 ----- - 6 files changed, 8 insertions(+), 45 deletions(-) - -diff --git a/drivers/gpu/drm/i915/intel_dp.c b/drivers/gpu/drm/i915/intel_dp.c -index b7b4cfdeb974..48cb8df5ae97 100644 ---- a/drivers/gpu/drm/i915/intel_dp.c -+++ b/drivers/gpu/drm/i915/intel_dp.c -@@ -1671,23 +1671,6 @@ static int intel_dp_compute_bpp(struct intel_dp *intel_dp, - return bpp;
