From ce58867ee17afecda7917e74a0d10afd7138c6d4 Mon Sep 17 00:00:00 2001 From: Gwan-gyeong Mun Date: Thu, 14 May 2020 09:07:28 +0300 Subject: [PATCH] drm/i915: Fix enabled infoframe states of lspcon MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit Compared to implementation of DP and HDMI's encoder->infoframes_enabled, the lspcon's implementation returns its active state. (we expect enabled infoframe states of HW.) It leads to pipe state mismatch error when ddi_get_config is called. Because the current implementation of lspcon is not ready to support readout infoframes, we need to return 0 here. In order to support readout to lspcon, we need to implement read_infoframe and infoframes_enabled. And set_infoframes also have to set an appropriate bit on crtc_state->infoframes.enable Cc: Ville Syrjälä Signed-off-by: Gwan-gyeong Mun Reviewed-by: Uma Shankar Signed-off-by: Jani Nikula Link: https://patchwork.freedesktop.org/patch/msgid/20200514060732.3378396-11-gwan-gyeong.mun@intel.com --- drivers/gpu/drm/i915/display/intel_lspcon.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/drivers/gpu/drm/i915/display/intel_lspcon.c b/drivers/gpu/drm/i915/display/intel_lspcon.c index d807c5648c87..6ff7b226f0a1 100644 --- a/drivers/gpu/drm/i915/display/intel_lspcon.c +++ b/drivers/gpu/drm/i915/display/intel_lspcon.c @@ -522,7 +522,7 @@ u32 lspcon_infoframes_enabled(struct intel_encoder *encoder, const struct intel_crtc_state *pipe_config) { /* FIXME actually read this from the hw */ - return enc_to_intel_lspcon(encoder)->active; + return 0; } void lspcon_resume(struct intel_lspcon *lspcon) -- 2.11.0
