+Subject: [PATCH] RaspberryPi: Don't suggest closed source gles driver when
+ using open source vc4
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+When building greenisland for RaspberryPi with open source GL drivers (vc4),
+cmake does not find closed source drivers (which is correct)
+
+| -- The following OPTIONAL packages have not been found:
+|
+| * BcmHost , Broadcom OpenGLES graphics libraries. , <http://www.broadcom.com/>
+
+Launching a hawaii session reports:
+
+| greenisland.qpa.deviceintegration: Preferred EGL device integration based on the hardware configuration: "brcm"
+
+which does not make sense - there were no integration libs for closed source
+RaspberryPi GLES built.
