[PATCH v2] drm/i915/dp: Send DPCD ON for MST before phy_up

by Lyude Paul

When doing a modeset where the sink is transitioning from D3 to D0 , it would sometimes be possible for the initial power_up_phy() to start timing out. This would only be observed in the last action before the sink went into D3 mode was intel_dp_sink_dpms(DRM_MODE_DPMS_OFF). We originally thought this might be an issue with us accidentally shutting off the aux block when putting the sink into D3, but since the DP spec mandates that sinks must wake up within 1ms while we have 100ms to respond to an ESI irq, this didn't really add up. Turns out that the problem is more subtle then that: It turns out that the timeout is from us not enabling DPMS on the MST hub before actually trying to initiate sideband communications. This would cause the first sideband communication (power_up_phy()), to start timing out because the sink wasn't ready to respond. Afterwards, we would call intel_dp_sink_dpms(DRM_MODE_DPMS_ON) in intel_ddi_pre_enable_dp(), which would actually result in waking up the sink so that sideband requests would work again. Since DPMS is what lets us actually bring the hub up into a state where sideband communications become functional again, we just need to make sure to enable DPMS on the display before attempting to perform sideband communications. Changes since v1: - Remove comment above if (!intel_dp->is_mst) - vsryjala - Move intel_dp_sink_dpms() for MST into intel_dp_post_disable_mst() to keep enable/disable paths symmetrical - Improve commit message - dhnkrn Signed-off-by: Lyude Paul <lyude(a)redhat.com> Cc: Dhinakaran Pandiyan <dhinakaran.pandiyan(a)intel.com> Cc: Ville Syrjälä <ville.syrjala(a)linux.intel.com> Cc: Laura Abbott <labbott(a)redhat.com> Cc: stable(a)vger.kernel.org Fixes: ad260ab32a4d9 ("drm/i915/dp: Write to SET_POWER dpcd to enable MST hub.") --- This email should hopefully actually be picked up by patchwork this time, hooray! drivers/gpu/drm/i915/intel_ddi.c | 6 ++++-- drivers/gpu/drm/i915/intel_dp_mst.c | 2 ++ 2 files changed, 6 insertions(+), 2 deletions(-) diff --git a/drivers/gpu/drm/i915/intel_ddi.c b/drivers/gpu/drm/i915/intel_ddi.c index a6672a9abd85..c0bf7419e1c1 100644 --- a/drivers/gpu/drm/i915/intel_ddi.c +++ b/drivers/gpu/drm/i915/intel_ddi.c @@ -2324,7 +2324,8 @@ static void intel_ddi_pre_enable_dp(struct intel_encoder *encoder, intel_prepare_dp_ddi_buffers(encoder, crtc_state); intel_ddi_init_dp_buf_reg(encoder); - intel_dp_sink_dpms(intel_dp, DRM_MODE_DPMS_ON); + if (!intel_dp->is_mst) + intel_dp_sink_dpms(intel_dp, DRM_MODE_DPMS_ON); intel_dp_start_link_train(intel_dp); if (port != PORT_A || INTEL_GEN(dev_priv) >= 9) intel_dp_stop_link_train(intel_dp); @@ -2427,7 +2428,8 @@ static void intel_ddi_post_disable_dp(struct intel_encoder *encoder, * Power down sink before disabling the port, otherwise we end * up getting interrupts from the sink on detecting link loss. */ - intel_dp_sink_dpms(intel_dp, DRM_MODE_DPMS_OFF); + if (!intel_dp->is_mst) + intel_dp_sink_dpms(intel_dp, DRM_MODE_DPMS_OFF); intel_disable_ddi_buf(encoder); diff --git a/drivers/gpu/drm/i915/intel_dp_mst.c b/drivers/gpu/drm/i915/intel_dp_mst.c index c3de0918ee13..2493bd1e0e59 100644 --- a/drivers/gpu/drm/i915/intel_dp_mst.c +++ b/drivers/gpu/drm/i915/intel_dp_mst.c @@ -176,6 +176,7 @@ static void intel_mst_post_disable_dp(struct intel_encoder *encoder, */ drm_dp_send_power_updown_phy(&intel_dp->mst_mgr, connector->port, false); + intel_dp_sink_dpms(intel_dp, DRM_MODE_DPMS_OFF); intel_dp->active_mst_links--; @@ -223,6 +224,7 @@ static void intel_mst_pre_enable_dp(struct intel_encoder *encoder, DRM_DEBUG_KMS("active links %d\n", intel_dp->active_mst_links); + intel_dp_sink_dpms(intel_dp, DRM_MODE_DPMS_ON); drm_dp_send_power_updown_phy(&intel_dp->mst_mgr, connector->port, true); if (intel_dp->active_mst_links == 0) intel_dig_port->base.pre_enable(&intel_dig_port->base, -- 2.14.3
