From 9324cf7fefd77883a9d8d7e0356b9dd45c13132b Mon Sep 17 00:00:00 2001 From: Daniel Vetter Date: Sat, 20 Oct 2012 21:13:05 +0200 Subject: [PATCH] drm/i915/dp: actually nack test request ... like the comment says. No idea whether this has any effect, but I guess it's better to not lie to the display by acking a test request and never following through with it. This goes back to the commit that originally introduced this code: commit a60f0e38d72a5e24085d6e7e27a4cadc20ae268a Author: Jesse Barnes Date: Thu Oct 20 15:09:17 2011 -0700 drm/i915: add DP test request handling Reviewed-by: Chris Wilson Meh'ed-by: Jesse Barnes Signed-off-by: Daniel Vetter --- drivers/gpu/drm/i915/intel_dp.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/drivers/gpu/drm/i915/intel_dp.c b/drivers/gpu/drm/i915/intel_dp.c index e0b91cb75d63..fda207e7a282 100644 --- a/drivers/gpu/drm/i915/intel_dp.c +++ b/drivers/gpu/drm/i915/intel_dp.c @@ -2074,7 +2074,7 @@ static void intel_dp_handle_test_request(struct intel_dp *intel_dp) { /* NAK by default */ - intel_dp_aux_native_write_1(intel_dp, DP_TEST_RESPONSE, DP_TEST_ACK); + intel_dp_aux_native_write_1(intel_dp, DP_TEST_RESPONSE, DP_TEST_NAK); } /* -- 2.11.0
