I wrote sputrace before generic tracing infrastrucure was available. Now that we have the generic event tracer we can convert it over and remove a lot of code: 8 files changed, 45 insertions(+), 285 deletions(-) To use it make sure CONFIG_EVENT_TRACING is enabled and then enable the spufs trace channel by echo 1 > /sys/kernel/debug/tracing/events/spufs/spufs_context/enable and then read the trace records using e.g. cat /sys/kernel/debug/tracing/trace Signed-off-by: Christoph Hellwig <hch@lst.de> Acked-by: Jeremy Kerr <jk@ozlabs.org> Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org>
