The startup function startup_32() for the kernel (also called the swapper or process 0) establishes memory management (paging tables and memory paging), detects the type of CPU and any additional functionality such as floating point capabilities, and then switches to non-architecture specific Linux kernel functionality via a call to start ...
In Linux, Logical Volume Manager (LVM) is a device mapper framework that provides logical volume management for the Linux kernel. Most modern Linux distributions are LVM-aware to the point of being able to have their root file systems on a logical volume. [3] [4] [5]
sysv-rc-conf, a TUI utility that selects which SysV-style init scripts will be run in each runlevel. When compared to its predecessors, AT&T's UNIX System III introduced a new style of system startup configuration, [9] which survived (with modifications) into UNIX System V and is therefore called the "SysV-style init".
The GUID Partition Table (GPT) is a standard for the layout of partition tables of a physical computer storage device, such as a hard disk drive or solid-state drive. It is part of the Unified Extensible Firmware Interface (UEFI) standard.
This is true for all versions of Mac OS X from 10.7 through macOS 10.12.x. TRIM is supported for RAID (0,1,4,5 & 10) volumes when using the third-party SoftRAID® application, including TRIM support with non-Apple SSD devices. (Note: TRIM for non-Apple SSD devices must be specifically enabled using the terminal command "sudo trimforce enable".)
On the Windows platform, many programs designed to monitor and report S.M.A.R.T. information will function only under an administrator account. BIOS and Windows ( Windows Vista and later) may detect S.M.A.R.T. status of hard disk drives and solid state drives, and give a prompt if the S.M.A.R.T. status is bad.
A block, a contiguous number of bytes, is the minimum unit of storage that is read from and written to a disk by a disk driver.The earliest disk drives had fixed block sizes (e.g. the IBM 350 disk storage unit (of the late 1950s) block size was 100 six-bit characters) but starting with the 1301 [8] IBM marketed subsystems that featured variable block sizes: a particular track could have blocks ...
Computer programming portal; Linux portal; io_uring [a] (previously known as aioring) is a Linux kernel system call interface for storage device asynchronous I/O operations addressing performance issues with similar interfaces provided by functions like read()/write() or aio_read()/aio_write() etc. for operations on data accessed by file descriptors.
