A page table entry holds the virtual page number for a given physical page.

Virtual Addressing using Segmentation

On the same system, how many pages are there in the virtual address space of a process?

The portion of trap.h and syscall.h files for xv6 are shown in the table below.

What will be the first TLB hit with the same TLB size and replacement policy as before?

Convert the VA 0x7011 to its PA.

For a segment that grows negatively, if a VA’s offset is out-of-bounds then a page fault will occur.

Now consider a function where we print the array contents in column order   void print_col_array(int *arr, int cols, int rows){    for(size_t i=0; i

The purpose of the TLB is to speed address translation.

Recall the initial rules for MLFQ are: If Priority(A) > Priority(B) then A runs If Priority(A) == Priority(B) then A&B run in RR Jobs start at top priority If a job uses its whole time slice then it is demoted These initial rules had several problems and needed to be changed.  What is one problem with these initial rules and the modification that was made to correct for this problem?
