Subject: Re: [PATCH] ACPI video: print out a warning message when duplicate video bus devices under the same VGA controller are detected
Date: Mon, 28 Dec 2009 21:40:48 -0500 (EST)	[thread overview]
Message-ID: <alpine.LFD.2.00.0912282138090.12663@localhost.localdomain> (raw)
In-Reply-To: <20091126051008.GB7874@srcf.ucam.org>

lets do this:

take this patch and modify it so that by default it fixes the bug
filed in http://bugzilla.kernel.org/show_bug.cgi?id=13577
ie. by default do what Windows 2006 seems to do and use the 1st
and ignore the duplicates.

continue to print out the warning, so we have some clue
how much we see this in the field.

and also modify the patch so that in case we are guessing wrong
about windows compatibility, we go back to current behaviour
and allow multiple devices.  say video.allow_duplicates or something

thanks,
Len Brown, Intel Open Source Technology Center
