Fill in the Gant chart based on these conditions: P, V, and context switch operations are instantaneous. Process PI starts at time 0; P2 at time 4; P3 at time 5; P4 at time 7; and P5 at time 9. 0 1 Initially semaphore s = 1; Process priorities are: P1 < P2<P3 <P4 < P5; //no priority inheritance After 3 time units P1 executes a P(s) call; after 3 more time units it executes a V(s) call and finishes. After 2 time units P2 executes a P(s) call; after 3 more time units it executes a V(s) call and finishes. After 2 time units P4 executes a P(s) call; after 3 more time units it executes a V(s) call and finishes. After 2 time unit P5 executes a P(s) call; after 3 more time units it executes a V(s) call and finishes. P3 does not execute any P(s) or V(s) calls and finishes after completing its 5 time units. Release from the semaphore queue is based on FIFO. 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 1133 24 25 26 Fill in the Gant chart based on these conditions: P, V, and context switch operations are instantaneous.
