* Finish process of moving the LinuxKPI module into the default kernel build.Hans Petter Selasky2015-10-291-0/+1
| | | | | | | | | | | | | | | | | | | | | | - Move all files related to the LinuxKPI into sys/compat/linuxkpi and its subfolders. - Update sys/conf/files and some Makefiles to use new file locations. - Added description of COMPAT_LINUXKPI to sys/conf/NOTES which in turn adds the LinuxKPI to all LINT builds. - The LinuxKPI can be added to the kernel by setting the COMPAT_LINUXKPI option. The OFED kernel option no longer builds the LinuxKPI into the kernel. This was done to keep the build rules for the LinuxKPI in sys/conf/files simple. - Extend the LinuxKPI module to include support for USB by moving the Linux USB compat from usb.ko to linuxkpi.ko. - Bump the FreeBSD_version. - A universe kernel build has been done.

* opt_global.h is never needed in SRCS lists.Warner Losh2014-11-181-1/+1

* Remove dependence on source tree options. Move all kernel moduleWarner Losh2014-08-111-1/+2
| | | | | | | | | | | | | | | | | | | | | options into kern.opts.mk and change all the places where we use src.opts.mk to pull in the options. Conditionally define SYSDIR and use SYSDIR/conf/kern.opts.mk instead of a CURDIR path. Replace all instances of CURDIR/../../etc with STSDIR, but only in the affected files. As a special compatibility hack, include bsd.owm.mk at the top of kern.opts.mk to allow the bare build of sys/modules to work on older systems. If the defaults ever change between 9.x, 10.x and current for these options, however, you'll wind up with the host OS' defaults rather than the -current defaults. This hack will be removed when we no longer need to support this build scenario. Reviewed by: jhb Differential Revision: https://phabric.freebsd.org/D529 Notes: svn path=/head/; revision=269812

* - Updated TOE support in the kernel.Navdeep Parhar2012-06-195-49/+31
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | - Stateful TCP offload drivers for Terminator 3 and 4 (T3 and T4) ASICs. These are available as t3_tom and t4_tom modules that augment cxgb(4) and cxgbe(4) respectively. The cxgb/cxgbe drivers continue to work as usual with or without these extra features. - iWARP driver for Terminator 3 ASIC (kernel verbs). T4 iWARP in the works and will follow soon. Build-tested with make universe. 30s overview ============ What interfaces support TCP offload? Look for TOE4 and/or TOE6 in the capabilities of an interface: # ifconfig -m | grep TOE Enable/disable TCP offload on an interface (just like any other ifnet capability): # ifconfig cxgbe0 toe # ifconfig cxgbe0 -toe Which connections are offloaded?

| | | | | | | | | | | | Use MACHINE_CPUARCH in preference to MACHINE_ARCH. The former is the source code location of the machine, the latter the binary output. In general, we want to use MACHINE_CPUARCH instead of MACHINE_ARCH unless we're tesitng for a specific target.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | - remove mbuf iovec - useful, but adds too much complexity when isolated to the driver - remove driver private caching - insufficient benefit over UMA to justify the added complexity and maintenance overhead - remove separate logic for managing multiple transmit queues, with the new drbr routines the control flow can be made to much more closely resemble legacy drivers - remove dedicated service threads, with per-cpu callouts one can get the same benefit much more simply by registering a callout 1 tick in the future if there are still buffered packets - remove embedded mbuf usage - Jeffr's changes will (I hope) soon be integrated greatly reducing the overhead of using kernel APIs for reference counting clusters - add hysteresis to descriptor coalescing logic - add coalesce threshold sysctls to allow users to decide at run-time between optimizing for forwarding / UDP or optimizing for TCP - add once per second watchdog to effectively close the very rare races occurring from coalescing - incorporate Navdeep's changes to the initialization path required to convert port and adapter locks back to ordinary mutexes (silencing BPF LOR complaints) - enable prefetches in get_packet and tx cleaning Reviewed by: navdeep@ MFC after: 2 weeks Notes: svn path=/head/; revision=194521

* This main goals of this project are:Qing Li2008-12-151-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 1. separating L2 tables (ARP, NDP) from the L3 routing tables 2. removing as much locking dependencies among these layers as possible to allow for some parallelism in the search operations 3. simplify the logic in the routing code, The most notable end result is the obsolescent of the route cloning (RTF_CLONING) concept, which translated into code reduction in both IPv4 ARP and IPv6 NDP related modules, and size reduction in struct rtentry{}. The change in design obsoletes the semantics of RTF_CLONING, RTF_WASCLONE and RTF_LLINFO routing flags. The userland applications such as "arp" and "ndp" have been modified to reflect those changes. The output from "netstat -r" shows only the routing entries. Quite a few developers have contributed to this project in the past: Glebius Smirnoff, Luigi Rizzo, Alessandro Cerri, and Andre Oppermann. And most recently: - Kip Macy revised the locking code completely, thus completing the last piece of the puzzle, Kip has also been conducting active functional testing - Sam Leffler has helped me improving/refactoring the code, and provided valuable reviews - Julian Elischer setup the perforce tree for me and has helped me maintaining that branch before the svn conversion Notes: svn path=/head/; revision=186119
