From: abdoulaye berthe <abdoulaye.berthe@xxxxxxx> [Why] When training with repeater the aux read interval must be set to repeater specific aux_red_interval. This value is always 100us for CR. [How] Check for repeater when setting the aux_rd_interval in channel equalization. Use the right offset in the aux_rd_interval array Signed-off-by: abdoulaye berthe <abdoulaye.berthe@xxxxxxx> Reviewed-by: Wenjing Liu <Wenjing.Liu@xxxxxxx> Acked-by: George Shen <George.Shen@xxxxxxx> Acked-by: Leo Li <sunpeng.li@xxxxxxx> --- drivers/gpu/drm/amd/display/dc/core/dc_link_dp.c | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) diff --git a/drivers/gpu/drm/amd/display/dc/core/dc_link_dp.c b/drivers/gpu/drm/amd/display/dc/core/dc_link_dp.c index 015fa0c52746..dfcd6421ee01 100644 --- a/drivers/gpu/drm/amd/display/dc/core/dc_link_dp.c +++ b/drivers/gpu/drm/amd/display/dc/core/dc_link_dp.c @@ -906,10 +906,10 @@ static enum link_training_result perform_channel_equalization_sequence( /* 3. wait for receiver to lock-on*/ wait_time_microsec = lt_settings->eq_pattern_time; - if (!link->is_lttpr_mode_transparent) + if (is_repeater(link, offset)) wait_time_microsec = translate_training_aux_read_interval( - link->dpcd_caps.lttpr_caps.aux_rd_interval[offset]); + link->dpcd_caps.lttpr_caps.aux_rd_interval[offset - 1]); wait_for_training_aux_rd_interval( link, -- 2.24.0 _______________________________________________ amd-gfx mailing list amd-gfx@xxxxxxxxxxxxxxxxxxxxx https://lists.freedesktop.org/mailman/listinfo/amd-gfx
