Subject: [POWERPC 1/9] spufs: return an error in spu_create is isolated create isnt supported
Date: Mon, 27 Nov 2006 19:18:52 +0100 [thread overview]
Message-ID: <20061127182429.315282000@arndb.de> (raw)
In-Reply-To: 20061127181851.796747000@arndb.de
From: Jeremy Kerr <jk@ozlabs.org>
This changes the spu_create system call to return an error (-ENODEV) if
and isolated spu context is requested on hardware that doesn't support
isolated mode.
Tested on systemsim with and without isolation support
