- Add fxp_start_body() and change fxp_start() to just acquire locks and then call fxp_start_body(). Places that would call fxp_start() with locks held (mutex recursion) now call fxp_start_body() directly. Remove MTX_RECURSE flag from sc_mtx. [gallatin] - Change fxp_attach() to work without the softc lock, saving interrupt hooking until the head of fxp_attach(). - Call ether_ifattach() before overriding ifp parameters. This reverts part of 1.155. - Remove multiple error paths in fxp_attach(). - Teardown interrupt in fxp_detach() before unlocking the softc. - Make sure mutex is not held in fxp_release() - Delete the miibus instance and/or self in fxp_release(), not in fxp_detach(). This can happen if attach fails partway through. - Move ifmedia_removeall to fxp_release() since attach may fail after media have been allocated. - Add locking to fxp_suspend, fxp_resume, fxp_start, fxp_intr, fxp_poll, fxp_tick, fxp_ioctl, fxp_watchdog. - Pass in ifp to fxp_intr_body since its callers sometimes already use it. - Add compatibility define for INTR_MPSAFE for 4.x. [gallatin] - You don't need to bzero softc. Ideas from: gallatin, mux Tested by: >400M packets of dd/ssh, NFS, ping on i386 UP
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 ``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.
