Hi, I am trying to use I/OAT on one of the newer woodcrest boxes. But not sure if things are configured properly since there seems to be no change in performance with I/OAT enabled or disabled. Following are the steps followed. 1. MSI (CONFIG_PCI_MSI) is enabled in kernel(2.6.16.21). 2. In kernel DMA configuration, following are enabled. Support for DMA Engines Network: TCP receive copy offload Test DMA Client Intel I/OAT DMA support 3. I manually load the ioatdma driver (modprobe ioatdma)
As per some documentation I read, when step #3 is performed successfully, directories dma0chanX is supposed to be created under /sys/class/dma but in my case, this directory stays empty. I don't see any messages in /var/log/messages. Any idea what is missing ?
