Subject: [PATCH] drm: drm init call takes large time
Date: Sun, 30 Jun 2013 05:41:59 +0500 [thread overview]
Message-ID: <1372552919-7791-1-git-send-email-abbas_raza@mentor.com> (raw)
From: Abbas Raza <Abbas_Raza@mentor.com>
DRM_INFO calls in the drm init routines are causing a large delay at boot time
due to which imx_drm_init call average takes around 26 ms. Changing DRM_INFO to
DRM_DEBUG reduces startup time to < 3ms.
