; Abstract:
|

|
|
;
|
||
|
|
; This module implements functions to support interlocked operations.
|
||
|
|
; Interlocked operations can only operate on nonpaged data.
|
||
|
|
;
|
||
|
|
; This module implements the fast call version of the interlocked
|
||
|
|
; fuctions.

; General Notes on Interlocked Procedures:
|
||
|
|
;
|
||
|
|
; These procedures assume that neither their code, nor any of
|
||
|
|
; the data they touch, will cause a page fault.
|
||
|
|
;
|
||
|
|
; They use spinlocks to achieve MP atomicity, iff it's an MP machine.
|
||
|
|
; (The spinlock macros generate zilch if NT_UP = 1, and
|
||
|
|
; we if out some aux code here as well.)
|
||
|
|
;
|
||
|
|
; They turn off interrupts so that they can be used for synchronization
|
||
|
|
; between ISRs and driver code. Flags are preserved so they can
|
||
|
|
; be called in special code (Like IPC interrupt handlers) that
|
||
|
|
; may have interrupts off.
