the slow path. Changes to the fast path will follow later. - Use the standard ULD registration and activation mechanism offered by if_cxgbe. This eliminates all the code that managed the list of offload_device structures. This simplifies the CPL dispatch too by eliminating t4tom_cpl_handler_register_flag and associated code. - Remove all unused or write-only fields from various structures (iscsi_socket, offload_device, cxgbei_ulp2_ddp_info, ulp_iscsi_info) - Eliminate the two line wrappers around malloc/free. While here, switch to using M_CXGBE for all allocations. - Simplify the page size settings in the chip (for iSCSI). This ULD "owns" these settings so it should simply write the values that it wants to the A_ULP_RX_ISCSI_TAGMASK and A_ULP_RX_ISCSI_PSZ registers. This eliminates the globals ddp_page_order[], ddp_page_shift[], page_idx and all related code. - Maintain the per-adapter ULD state in one data structure instead of two. This consolidates struct offload_device and struct cxgbei_ulp2_ddp_info and into struct cxgbei_data, which is stored in adapter->iscsi_softc. - Leave socket->so_emuldata alone, it exists for a different purpose (which is definitely not iSCSI). Store the per-socket offload state in a new field in struct icl_conn instead. (The new field exists only in this project branch and hasn't been reviewed for inclusion into head yet). - Switch to the system version of mbufq. - Tidy up the CPL/callback dispatch from if_cxgbe/t4_tom into cxgbei. The tid/toepcb is always available (t4_tom has looked it up) so it's a waste of time looking it up again. |

This is the top level of the FreeBSD source directory. This file was last revised on: $FreeBSD$ For copyright information, please see the file COPYRIGHT in this directory (additional copyright information also exists for some sources in this tree - please see the specific source directories for more information). The Makefile in this directory supports a number of targets for building components (or all) of the FreeBSD source tree, the most commonly used one being ``world'', which rebuilds and installs everything in the FreeBSD system from the source tree except the kernel, the kernel-modules and the contents of /etc. The ``world'' target should only be used in cases where the source tree has not changed from the currently running version. See: http://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/makeworld.html for more information, including setting make(1) variables. The ``buildkernel'' and ``installkernel'' targets build and install the kernel and the modules (see below). Please see the top of the Makefile in this directory for more information on the standard build targets and compile-time flags. Building a kernel is a somewhat more involved process, documentation for which can be found at: http://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/kernelconfig.html And in the config(8) man page. Note: If you want to build and install the kernel with the ``buildkernel'' and ``installkernel'' targets, you might need to build world before. More information is available in the handbook. The sample kernel configuration files reside in the sys/<arch>/conf sub-directory (assuming that you've installed the kernel sources), the file named GENERIC being the one used to build your initial installation kernel. The file NOTES contains entries and documentation for all possible devices, not just those commonly used. It is the successor of the ancient LINT file, but in contrast to LINT, it is not buildable as a kernel but a pure reference and documentation file.
