Primitives:

• prim.c contains Windows primitives for OS allocation.

Event Tracing for Windows (ETW)

• etw.h is generated from etw.man which contains the manifest for mimalloc events. (100 is an allocation, 101 is for a free)

• etw-mimalloc.wprp is a profile for the Windows Performance Recorder (WPR). In an admin prompt, you can use:

  > wpr -start src\prim\windows\etw-mimalloc.wprp -filemode
  > <my mimalloc program>
  > wpr -stop test.etl
  

  and then open test.etl in the Windows Performance Analyzer (WPA).
