Types of System Calls (Cont.)    Device management  request device, release device  read, write, reposition  get device attributes, set device attributes  logically attach or detach devices Information maintenance  get time or date, set time or date  get system data, set system data  get and set process, file, or device attributes Communications  create, delete communication connection  send, receive messages  transfer status information  attach and detach remote devices Operating System Concepts – 8th Edition 2.21 Silberschatz, Galvin and Gagne ©2009

I/O Structure  After I/O starts, control returns to user program without waiting for I/O completion  System call – request to the operating system to allow user to wait for I/O completion  Device-status table contains entry for each I/O device indicating its type, address, and state  Operating system indexes into I/O device table to determine device status and to modify table entry to include interrupt Operating System Concepts with Java – 8th Edition 1.13 Silberschatz, Galvin and Gagne ©2009

I/O Structure After I/O starts, control returns to user program only upon I/O completion  Wait instruction idles the CPU until the next interrupt  Wait loop (contention for memory access)  At most one I/O request is outstanding at a time, no simultaneous I/O processing  After I/O starts, control returns to user program without waiting for I/O completion  System call – request to the operating system to allow user to wait for I/O completion  Device-status table contains entry for each I/O device indicating its type, address, and state  Operating system indexes into I/O device table to determine device status and to modify table entry to include interrupt  Operating System Concepts – 8th Edition 1.15 Silberschatz, Galvin and Gagne ©2009
