- In ntoskrnl_var.h, I had defined compat macros for ntoskrnl_acquire_spinlock() and ntoskrnl_release_spinlock() but never used them. This is fortunate since they were stale. Fix them to work properly. (In Windows/x86 KeAcquireSpinLock() is a macro that calls KefAcquireSpinLock(), which lives in HAL.dll. To imitate this, ntoskrnl_acquire_spinlock() is just a macro that calls hal_lock(), which lives in subr_hal.o.) - Add macros for ntoskrnl_raise_irql() and ntoskrnl_lower_irql() that call hal_raise_irql() and hal_lower_irql(). - Use these macros in kern_ndis.c, subr_ndis.c and subr_ntoskrnl.c. - Along the way, I realised subr_ndis.c:ndis_lock() was not calling hal_lock() correctly (it was using the FASTCALL2() wrapper when in reality this routine is FASTCALL1()). Using the ntoskrnl_acquire_spinlock() fixes this. Not sure if this actually caused any bugs since hal_lock() would have just ignored what was in %edx, but it was still bogus. This hides many of the uses of the FASTCALLx() macros which makes the code a little cleaner. Should not have any effect on generated object code, other than the one fix in ndis_lock().
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.
