The following items will be graded for this checkpoint.

Programming assignment:

• src/mmu.c
  
  
  • mmu_translate
  
  
  • mmu_free
  
  
  • mmu_map
  
  
  
  


• src/main.c
  
  
  • Add mappings for all sections and select the proper permissions (RWX).
    
    
    • Most of these are already done for you, but you need to double check the mappings.
    
    
    
    
  
  
  • Turn on the MMU (uncomment CSR_WRITE("satp", SATP_KERNEL))
  
  
  
  

Students must have working knowledge of the following code already written for you:

• src/lock.c
  
  
  • Mutex data structure
  
  
  • mutex_trylock
  
  
  • mutex_unlock
  
  
  
  


• src/page.c
  
  
  • page_alloc
  
  
  • page_zalloc
  
  
  • page_free
  
  
  
  


• src/kmalloc.c
  
  
  • kmalloc
  
  
  • kzalloc
  
  
  
  


• sbi/src/*
