From dd519418f5130ce9ca08256b3383bf0e529dbf81 Mon Sep 17 00:00:00 2001 From: Jani Nikula Date: Thu, 26 Apr 2018 11:25:25 +0300 Subject: [PATCH] drm/i915/dp: move link_bw and rate_select debugging where used We call intel_dp_compute_rate() in intel_dp_compute_config() only to be able to debug log the link_bw and rate_select parameters; we don't use the parameters here for anything else. We call intel_dp_compute_rate() again during link training where we actually need and use the parameters. Move the debug logging of link_bw and rate_select to intel_dp_link_training_clock_recovery(), and clean up the extra intel_dp_compute_rate() call and extra clutter from the already overcrowded intel_dp_compute_config(). v2: Rewrote commit message (Rodrigo, Manasi) Reviewed-by: Manasi Navare Signed-off-by: Jani Nikula Link: https://patchwork.freedesktop.org/patch/msgid/c5cf6a179e2d244eceb6bb80a792765d9efbee4f.1524730974.git.jani.nikula@intel.com --- drivers/gpu/drm/i915/intel_dp.c | 9 ++------- drivers/gpu/drm/i915/intel_dp_link_training.c | 5 +++++ 2 files changed, 7 insertions(+), 7 deletions(-) diff --git a/drivers/gpu/drm/i915/intel_dp.c b/drivers/gpu/drm/i915/intel_dp.c index 5f4b30faf6a2..81cf363e71af 100644 --- a/drivers/gpu/drm/i915/intel_dp.c +++ b/drivers/gpu/drm/i915/intel_dp.c @@ -1706,7 +1706,6 @@ intel_dp_compute_config(struct intel_encoder *encoder, int bpp, mode_rate; int link_avail, link_clock; int common_len; - uint8_t link_bw, rate_select; bool reduce_m_n = drm_dp_has_quirk(&intel_dp->desc, DP_DPCD_QUIRK_LIMITED_M_N); @@ -1852,12 +1851,8 @@ found: pipe_config->pipe_bpp = bpp; pipe_config->port_clock = intel_dp->common_rates[clock]; - intel_dp_compute_rate(intel_dp, pipe_config->port_clock, - &link_bw, &rate_select); - - DRM_DEBUG_KMS("DP link bw %02x rate select %02x lane count %d clock %d bpp %d\n", - link_bw, rate_select, pipe_config->lane_count, - pipe_config->port_clock, bpp); + DRM_DEBUG_KMS("DP lane count %d clock %d bpp %d\n", + pipe_config->lane_count, pipe_config->port_clock, bpp); DRM_DEBUG_KMS("DP link bw required %i available %i\n", mode_rate, link_avail); diff --git a/drivers/gpu/drm/i915/intel_dp_link_training.c b/drivers/gpu/drm/i915/intel_dp_link_training.c index f59b59bb0a21..3fcaa98b9055 100644 --- a/drivers/gpu/drm/i915/intel_dp_link_training.c +++ b/drivers/gpu/drm/i915/intel_dp_link_training.c @@ -139,6 +139,11 @@ intel_dp_link_training_clock_recovery(struct intel_dp *intel_dp) intel_dp_compute_rate(intel_dp, intel_dp->link_rate, &link_bw, &rate_select); + if (link_bw) + DRM_DEBUG_KMS("Using LINK_BW_SET value %02x\n", link_bw); + else + DRM_DEBUG_KMS("Using LINK_RATE_SET value %02x\n", rate_select); + /* Write the link configuration data */ link_config[0] = link_bw; link_config[1] = intel_dp->lane_count; -- 2.11.0
