along with KeInitializeTimerEx(), KeSetTimer(), KeSetTimerEx(), KeCancelTimer(), KeReadStateTimer() and KeInitializeDpc(). I don't know for certain that these will make the Atheros driver happy since I don't have the card/driver combo needed to test it, but these are fairly independent so they shouldn't break anything else. - Debugger() is present even in kernels without options DDB, so no conditional compilation is necessary (pointed out by bde). - Remove the extra km_acquirecnt member that I added to struct kmutant and embed it within an unused portion of the structure instead, so that we don't make the structure larger than it's defined to be in Windows. I don't know what crack I was smoking when I decided it was ok to do this, but it's worn off now.

* The ndis_kspin_lock type is called KSPIN_LOCK in MS-Windows.
|
|
* According to the Windows DDK header files, KSPIN_LOCK is defined like this:
|
|
* typedef ULONG_PTR KSPIN_LOCK;
|
|
*
|
|
* From basetsd.h (SDK, Feb. 2003):
|
|
* typedef [public] unsigned __int3264 ULONG_PTR, *PULONG_PTR;
|
|
* typedef unsigned __int64 ULONG_PTR, *PULONG_PTR;
|
|
* typedef _W64 unsigned long ULONG_PTR, *PULONG_PTR;
|
|
*
|
|
* The keyword __int3264 specifies an integral type that has the following
|
|
* properties:
|
|
* + It is 32-bit on 32-bit platforms
|
|
* + It is 64-bit on 64-bit platforms
|
|
* + It is 32-bit on the wire for backward compatibility.
|
|
* It gets truncated on the sending side and extended appropriately
|
|
* (signed or unsigned) on the receiving side.
|
|
*
|
|
* Thus register_t seems the proper mapping onto FreeBSD for spin locks.
