Subject: [PATCH 8/9] [RESEND] fbdev: Detect primary display device
Date: Mon, 28 May 2007 18:30:04 +0800 [thread overview]
Message-ID: <465AAF2C.6070602@gmail.com> (raw)
In-Reply-To: <Pine.LNX.4.64.0705281037080.4790@anakin>
Add function helper, fb_is_primary_device(). Given struct fb_info, it will
return a nonzero value if the device is the primary display.
Currently, only the i386 is supported where the function checks for the
IORESOURCE_ROM_SHADOW flag.

Add function helper, fb_is_primary_device(). Given struct fb_info, it will
return a nonzero value if the device is the primary display.
Currently, only the i386 is supported where the function checks for the
IORESOURCE_ROM_SHADOW flag.
