DXE Dispatcher.
Step #1 - When a FV protocol is added to the system every driver in the FV
is added to the mDiscoveredList. The SOR, Before, and After Depex are
pre-processed as drivers are added to the mDiscoveredList. If an Apriori
file exists in the FV those drivers are addeded to the
mScheduledQueue. The mFvHandleList is used to make sure a
is added to the mDiscoveredList. The SOR, Before, and After Depex are
pre-processed as drivers are added to the mDiscoveredList. If an Apriori
file exists in the FV those drivers are addeded to the
mScheduledQueue. The mFvHandleList is used to make sure a
FV is only processed once.
Step #2 - Dispatch. Remove driver from the mScheduledQueue and load and
start it. After mScheduledQueue is drained check the
mDiscoveredList to see if any item has a Depex that is ready to
start it. After mScheduledQueue is drained check the
mDiscoveredList to see if any item has a Depex that is ready to
be placed on the mScheduledQueue.
Step #3 - Adding to the mScheduledQueue requires that you process Before
Step #3 - Adding to the mScheduledQueue requires that you process Before
and After dependencies. This is done recursively as the call to add
to the mScheduledQueue checks for Before and recursively adds
all Befores. It then addes the item that was passed in and then
to the mScheduledQueue checks for Before and recursively adds
all Befores. It then addes the item that was passed in and then
processess the After dependecies by recursively calling the routine.
