OS_Structure_2b Micrоkernel The cоntext fоr this question is the sаme аs the previous question. 2. You аre evaluating a microkernel-based OS following the principles of the L3 microkernel. The processor architecture on which this OS is running has the following features: A byte-addressable 32-bit hardware address space. Paged virtual memory system with a processor register called PTBR that points to the page table in memory to enable hardware address translation. A TLB which DOES NOT support Address space IDs. A pair of hardware-enforced segment registers (lower and upper bound of virtual addresses) which limit the virtual address space that can be accessed by a process running on the processor. The use of segment registers can be toggled on or off by the user. A virtually-indexed physically-tagged processor cache. b. [2 points] (List all that apply; Note: +x for correct choice; -x for incorrect choice) Packing multiple small protection domain into one hardware address space will result in: A) Reduced explicit cost on context switch between protection domains B) Reduced page faults in the system C) Reduced TLB misses D) Increased misses in the cache

[2 points] (List all that apply; Note: +x for correct choice; -x for incorrect choice) A context switch from one large protection domain to another will result in: A) The TLB needing to be flushed B) The cache needing to be flushed C) Changing the PTBR D) Implicit costs decreasing
