svn path=/trunk/; revision=8675
 2004-03-12 23:03:21 +00:00
David Welch f12f44e036 - Actually I realised it isn't valid to touch the object at all after 
decrementing the reference count unless the reference count was one. I
also removed the retention check in ObfReferenceObject since I couldn't
see how this would ever be needed.

svn path=/trunk/; revision=8659
 2004-03-12 00:46:35 +00:00
David Welch c61a3955d5 - Use the return value from calling InterlockedDecrement on the reference 
count when checking whether the object should be retained. This fixes
a race whereby one thread decrements the value to one, another thread
come in and decrements the value to zero and starts the delete, the
first thread then comes back, does retention checks and finds the
reference count is now zero and then bugchecks because the object is
already being deleted.

svn path=/trunk/; revision=8658
 2004-03-12 00:28:13 +00:00

David Welch 01d3124925 - Made KeBugCheckEx into a call to KeBugCheckExWithTf. 
- If file logging is in use then dump the last messages from the ringbuffer
on a bugcheck so the user can see them if the system was in graphics mode
when it crashed.

svn path=/trunk/; revision=8653
 2004-03-11 21:50:24 +00:00
David Welch 060aa03ca6 - Added KeSaveFloatingPoint and KeRestoreFloatingPointState to the old

svn path=/trunk/; revision=8616

David Welch 1fbda72a7a - Replaced some common sequences of inline assembly with macros. Avoid 
having compiler checks scattered all over the place.
- Added some disabled code to KiDumpTrapFrame that dumps every address
on the stack that could be a return address. This is quite handy for
debugging crashes in modules compiled with fpo.

svn path=/trunk/; revision=8615
 2004-03-09 21:49:54 +00:00
David Welch e04ce16d15 - Fixed check for an out of range index in {Get/Set}{Class/Window}Long

 2004-03-07 04:44:41 +00:00
David Welch 75860969fe - Added an implemention of VideoPortGetProcAddress 
- ati2mtag calls VideoPortGetAccessRanges with *DeviceId == 0 so treat
that as matching an device id.
- Return STATUS_SUCCESS from VideoPortSetTrappedEmulatorPorts even though
the data is ignored.

svn path=/trunk/; revision=8560
 2004-03-07 04:43:55 +00:00
David Welch ff81e5e1b0 - Use an event rather than a semaphore to wake up the thread that writes
