This patch series is the a full release of the Intel(R) I/O Acceleration Technology (I/OAT) for Linux. It includes an in kernel API for offloading memory copies to hardware, a driver for the I/OAT DMA memcpy engine, and changes to the TCP stack to offload copies of received networking data to application space. Changes from last posting: Fixed a struct ioat_dma_chan memory leak on driver unload. Changed a lock that was never held in atomic contexts to a mutex as part of avoiding unneeded GFP_ATOMIC allocations. These changes apply to Linus' tree as of commit 6810b548b25114607e0814612d84125abccc0a4f [PATCH] x86_64: Move ondemand timer into own work queue They are available to pull from git://63.64.152.142/~cleech/linux-2.6 ioat-2.6.17 There are 9 patches in the series: 1) The memcpy offload APIs and class code 2) The Intel I/OAT DMA driver (ioatdma) 3) Core networking code to setup networking as a DMA memcpy client 4) Utility functions for sk_buff to iovec offloaded copy 5) Structure changes needed for TCP receive offload 6) Rename cleanup_rbuf to tcp_cleanup_rbuf 7) Make sk_eat_skb aware of early copied packets 8) Add a sysctl to tune the minimum offloaded I/O size for TCP 9) The main TCP receive offload changes -- Chris Leech I/O Acceleration Technology Software Development LAN Access Division / Digital Enterprise Group
