To maximize the performance, efficiency, and reliability of your HP-UX sysem, you need to know what's going on under the hood. HP-UX 11i Internals goes beyond generic UNIX internals, showing exactly how HP-UX works in PA-RISC environments.HP experts Cooper and Moore systematically illuminate HP-UX kernel data structures and algorithms for memory management, process and thread scheduling, I/O control, files and file systems, resource management, and more. They focus on HP-UX 11i, while also offering valuable insight for those using earlier versions. * PA-RISC architecture: register set, virtual memory, key instructions, and procedure calling conventions * HP-UX kernel organization: hardware-dependent and independent data structures * Process and thread management: proc tables, memory management, scheduling, and the complete process/thread lifecycle * System-wide memory resources: allocation and mapping to physical memory * HP-UX paging and swapping * Files and filesystems: traditional UNIX filesystems, HFS, VFS, and dynamic buffer cache * I/O and device management: addressing, DMA, interrupts, device files, I/O configuration, device driver assignments, and I/O request pathways * Logical Volume Management (LVM): abstracting physical disks from the disk I/O system * HP-UX multiprocessing: challenges, data structures, and interfaces * Kernel communication services: semaphores, message queues, shared memory, signals, and the kernel "callout" system * Signaling in complex threaded environments * System initialization, from vmunix to init: running HP-UX on diverse platforms"
