that I added recently: - When a periodic timer fires, it's automatically re-armed. We must make sure to re-arm the timer _before_ invoking any caller-supplied defered procedure call: the DPC may choose to call KeCancelTimer(), and re-arming the timer after the DPC un-does the effect of the cancel. - Fix similar issue with periodic timers in subr_ndis.c. - When calling KeSetTimer() or KeSetTimerEx(), if the timer is already pending, untimeout() it first before timeout()ing it again. - The old Atheros driver for the 5211 seems to use KeSetTimerEx() incorrectly, or at the very least in a very strange way that doesn't quite follow the Microsoft documentation. In one case, it calls KeSetTimerEx() with a duetime of 0 and a period of 5000. The Microsoft documentation says that negative duetime values are relative to the current time and positive values are absolute. But it doesn't say what's supposed to happen with positive values that less than the current time, i.e. absolute values that are in the past. Lacking any further information, I have decided that timers with positive duetimes that are in the past should fire right away (or in our case, after only 1 tick). This also takes care of the other strange usage in the Atheros driver, where the duetime is specified as 500000 and the period is 50. I think someone may have meant to use -500000 and misinterpreted the documentation. - Also modified KeWaitForSingleObject() and KeWaitForMultipleObjects() to make the same duetime adjustment, since they have the same rules regarding timeout values. - Cosmetic: change name of 'timeout' variable in KeWaitForSingleObject() and KeWaitForMultipleObjects() to 'duetime' to avoid senseless (though harmless) overlap with timeout() function name. With these fixes, I can get the 5211 card to associate properly with my adhoc net using driver AR5211.SYS version 2.4.1.6. |

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.
