identifiers, to openfirmio.h as OFIOCMAXNAME, so programs can use it for buffer sizes etc. Note: Although this is only a rough upper limit to make the code more robust and to prevent the allocation of ridiculous amounts of memory, the current limit of one page (8191 + '\0' in openfirm_getstr()) still appears a bit high. The maximum length of OFW property names is 31. I didn't find a maximum length for the device identifiers in the OFW documentation but it certainly is much smaller than 8191, too. - Enable the OFIOCSET ioctl, i.e. move it out from under #if 0. - Don't use openfirm_getstr() for the property value in OFIOCSET, there are also properties whose values aren't strings and it makes sense to use a different maximum length for property values than OFW_NAME_MAX/ OFIOCMAXNAME. The maximum accepted property value is defined in openfirmio.h as OFIOCMAXVALUE (currently the maximum size of the value of the nvramrc property). - Make OFIOCSET not return EINVAL when OF_setprop() returns a different length for the written value than it was told to write, this is normal for the text string values of the properties in the OFW /options node. Instead, only return EINVAL if OF_setprop() returned -1 (value could not be written or property could not be created). Add a comment about the specialty of the OFW /options node. - Make OFIOCSET return the length of the written value returned by OF_setprop(), just like OF_getprop() does. Quite useful, at least for debugging. Reviewed by: tmm |

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.
