From 465242ee36ebd5a4f31df64692c634f402c8f2d9 Mon Sep 17 00:00:00 2001 From: Michel Thierry Date: Sat, 17 Aug 2019 02:38:24 -0700 Subject: [PATCH] drm/i915/tgl: add support for reading the timestamp frequency There are no changes with respect to GEN11, which Paulo wrote. This gets rid of the "Missing switch case in read_timestamp_frequency" message at boot for Tiger Lake. [ Lucas: BSpec: 10742 and 9024, but there's a mismatch on the values. Let's say a glitch in the spec. Tested locally and it works. ] Cc: Paulo Zanoni Cc: Lionel Landwerlin Signed-off-by: Michel Thierry Reviewed-by: Lucas De Marchi Signed-off-by: Lucas De Marchi Link: https://patchwork.freedesktop.org/patch/msgid/20190817093902.2171-3-lucas.demarchi@intel.com --- drivers/gpu/drm/i915/intel_device_info.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/drivers/gpu/drm/i915/intel_device_info.c b/drivers/gpu/drm/i915/intel_device_info.c index 2a39b52c3582..d0ed44d33484 100644 --- a/drivers/gpu/drm/i915/intel_device_info.c +++ b/drivers/gpu/drm/i915/intel_device_info.c @@ -716,7 +716,7 @@ static u32 read_timestamp_frequency(struct drm_i915_private *dev_priv) } return freq; - } else if (INTEL_GEN(dev_priv) <= 11) { + } else if (INTEL_GEN(dev_priv) <= 12) { u32 ctc_reg = I915_READ(CTC_MODE); u32 freq = 0; -- 2.30.2
