54 /*Setup has two phases:
|
|
Me@0
|
55 * 1) Semantic layer first calls init_VMS, which creates masterEnv, and puts
|
|
Me@8
|
56 * the master virt procr into the work-queue, ready for first "call"
|
|
Me@8
|
57 * 2) Semantic layer then does its own init, which creates the seed virt
|
|
Me@8
|
58 * procr inside the semantic layer, ready to schedule it when
|
|
Me@0
|
59 * asked by the first run of the masterLoop.
|
|
Me@0
|
60 *
|
|
Me@0
|
61 *This part is bit weird because VMS really wants to be "always there", and
|
|
Me@0
|
62 * have applications attach and detach.. for now, this VMS is part of
|
|
Me@0
|
63 * the app, so the VMS system starts up as part of running the app.
|
|
Me@0
|
64 *
|
|
Me@8
|
65 *The semantic layer is isolated from the VMS internals by making the
|
|
Me@8
|
66 * semantic layer do setup to a state that it's ready with its
|
|
Me@8
|
67 * initial virt procrs, ready to schedule them to slots when the masterLoop
|
|
Me@0
|
68 * asks. Without this pattern, the semantic layer's setup would
|
|
Me@8
|
69 * have to modify slots directly to assign the initial virt-procrs, and put
|
|
Me@31
|
70 * them into the readyToAnimateQ itself, breaking the isolation completely.
|
|
Me@0
|
71 *
|
|
Me@0
|
72 *
|
|
Me@8
|
73 *The semantic layer creates the initial virt procr(s), and adds its
|
|
Me@8
|
74 * own environment to masterEnv, and fills in the pointers to
|
|
Me@0
|
75 * the requestHandler and slaveScheduler plug-in functions
