Subject: [PATCH 3/8] drm/i915: clear the FPGA_DBG_RM_NOCLAIM bit at driver init
Date: Mon, 18 Feb 2013 19:00:22 -0300 [thread overview]
Message-ID: <1361224828-3730-4-git-send-email-przanoni@gmail.com> (raw)
In-Reply-To: <1361224828-3730-1-git-send-email-przanoni@gmail.com>
From: Paulo Zanoni <paulo.r.zanoni@intel.com>
Otherwise, if the BIOS did anything wrong, our first I915_{WRITE,READ}
will give us "unclaimed register" messages.
V2: Even earlier.
