Message-ID: <20080221123534.GA17716@ingate.macqel> Mime-Version: 1.0 Content-Type: text/plain; charset=us-ascii Content-Disposition: inline User-Agent: Mutt/1.4.1i Sender: linux-kernel-owner@vger.kernel.org List-ID: X-Mailing-List: linux-kernel@vger.kernel.org Dear list, I have just compiled linux-2.6.24 for a MPC8540 target using a MPC8540 specific gcc. I then got thousands of "SPE used in kernel" messages. Looking at the sources I ifdeffed out the printk call in KernelSPE, and I now have a silent kernel, that seems to work fine. Is there something wrong in my setting and should I look further to debug this problem or is this perfectly normal ? I wonder why a kernel configured for E500 using a E500-specific gcc triggers this message. Is it invalid to use SPE instructions in the kernel ? Philippe
