receive queues are shared among all PMLs, they are declared in the base PML, and the selected PML is in charge of initializing and releasing them. The CM PML is slightly different compared with OB1 or DR. Internally it use 2 different types of requests: light and heavy. However, now with this patch both types of requests are stored in the same queue, and cast appropriately on the allocation macro. This means we might use less memory than we allocate, but in exchange we got full support for most of the parallel debuggers. Another thing with this patch, is that now for all PML (CM included) the basic PML requests start with the same fields, and they are declared in the same order in the request structure. Moreover, the fields have been moved in such a way that only one volatile/atomic will exist per line of cache (hopefully). This commit was SVN r15346.
