allowing it to be a filter/"fast" handler. Locking the interrupt
handlers with a spin lock is mainly a requirement in schizo(4)
but as we ought to register the spin lock anyway it should not
hurt to take advantage of it in psycho(4).
- Pass both a driver_filter_t and a driver_intr_t argument to
psycho_set_intr(), allowing to get rid of the FAST interrupt
flag hack.
- Don't register the over-temperature interrupt handler as filter/
"fast" handler so shutdown_nice() can acquire the process lock.
- Use bus_{read,write}_8() instead of bus_space_{read,write}_8()
in order to get rid of sc_bushandle and sc_bustag in the softc.
- Correct the debug output for adjusting the subordinate bus number.
- Remove the banal and outdated above psycho_filter_stub().
- Fix some white space nits.
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.
