waiting for av event flag - See 5.2 9.6
Most is implemented, but not some waitqueues, due to some forgotten problems. Must verify that common event flags works properly. Also something in the top of exe_wait modifies the return stack.
| efn | event flag number | |
| mask | event flag mask | |
| waitallflag | should wait for all set in mask | |
| dummy | for the stack return address change |
set ipl 2
legal efn check
determine event flag cluster
test if common event flag and existance
sched spinlock
find waitqueue
if the wait condition is not satisfied
unlock sched
if the wait condition is satisfied
handle waitall flag
TODO: check if waitall and mask is handled right
handle waitall set sts flag
TODO: check if this insque still has problems. should it be here
if unsatisfied, fix the return address
