From 018f52c9c3c40b5ba22586b6ced6c3f5339848d6 Mon Sep 17 00:00:00 2001 From: Paulo Zanoni Date: Sat, 2 Nov 2013 21:07:35 -0700 Subject: [PATCH] drm/i915/bdw: pretend we have LPT LP on Broadwell MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The platforms we currently have all have LPT LP on them. As such, we have no way to identify the new WPT PCH that will ship with Broadwell. NOTE: For all purposes relevant to the driver that this point, LPT and WPT are equivalent. Therefore there should be no need to actually change this for some time. v2: Don't assign dev_priv->num_pch_pll any more. v3: Rebase on top of the PCH detection changes for virtualized enviroments. v4: Wrote commit message Signed-off-by: Paulo Zanoni (v1) Signed-off-by: Daniel Vetter (v3) Signed-off-by: Ben Widawsky Reviewed-by: Ville Syrjälä Signed-off-by: Daniel Vetter --- drivers/gpu/drm/i915/i915_drv.c | 6 ++++++ 1 file changed, 6 insertions(+) diff --git a/drivers/gpu/drm/i915/i915_drv.c b/drivers/gpu/drm/i915/i915_drv.c index c0ab5d460692..a78e7798ec6b 100644 --- a/drivers/gpu/drm/i915/i915_drv.c +++ b/drivers/gpu/drm/i915/i915_drv.c @@ -453,6 +453,12 @@ void intel_detect_pch(struct drm_device *dev) DRM_DEBUG_KMS("Found LynxPoint LP PCH\n"); WARN_ON(!IS_HASWELL(dev)); WARN_ON(!IS_ULT(dev)); + } else if (IS_BROADWELL(dev)) { + dev_priv->pch_type = PCH_LPT; + dev_priv->pch_id = + INTEL_PCH_LPT_LP_DEVICE_ID_TYPE; + DRM_DEBUG_KMS("This is Broadwell, assuming " + "LynxPoint LP PCH\n"); } else { goto check_next; }
