Subject: MPC8540 : What's "SPE used in kernel" ?
Date: Fri, 22 Feb 2008 10:50:22 +0100 [thread overview]
Message-ID: <20080222095022.GA635@ingate.macqel> (raw)

Dear list,
I have just compiled linux-2.6.24 for a MPC8540 target using a MPC8540
specific gcc.
I then got tan infinity 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 and compiled by a E500-specific gcc
triggers this message. Is it invalid to use SPE instructions in the kernel
or do I misunderstand the message ?
Philippe
