Currently, all Infiniband users must create a process for polling their completion queues (or rely on a regular hook such as netdev_poll() in ipoib.c). Move instead to a model whereby the Infiniband core maintains a single process calling ib_poll_eq(), and polling the event queue triggers polls of the applicable completion queues. (At present, the Infiniband core simply polls all of the device's completion queues.) Polling a completion queue will now implicitly refill all attached receive work queues; this is analogous to the way that netdev_poll() implicitly refills the RX ring. Infiniband users no longer need to create a process just to poll their completion queues and refill their receive rings. |

README
gPXE README File gPXE is an implementation of the PXE specification for network booting, with extensions to allow additional features such as booting via HTTP, iSCSI, and AoE. In generally, gPXE is compatible with the industry-standard PXE specification, and also supports Etherboot .nbi file loading and some additional protocols and features. For more detailed information about gPXE, please visit our project website at: http://etherboot.org/ BUILDING gPXE IMAGE FROM SOURCE If you don't want to install development tools, and have access to the Web, you can get gPXE and Etherboot ROM images made on demand from http://rom-o-matic.net/ If you would like to compile gPXE images from source, here are some tips. We normally compile gPXE images on x86, 32-bit Linux machines. It is possible to also use x86-64 machines. We use gcc compiler options to create 32-bit output. It is important to have the necessary software packages installed. A gcc-based toolchain is required. The following packages (at least) are required: - a gcc tool chain (gcc 3.x or gcc 4.x) - binutils - perl - syslinux - mtools To test your environment, cd to the "src" directory and type: make You should see a lot of output, and when it stops, the "bin" directory should be populated with gPXE images and object files. To learn more about what to build and how to use gPXE, please visit our project website at http://etherboot.org/ , particularly the "howto" section.
