modprobe is a Linux program originally written by Rusty Russell and used to add a loadable kernel module to the Linux kernel or to remove a loadable kernel module from the kernel. It is commonly used indirectly: udev relies upon modprobe to load drivers for automatically detected hardware. [citation needed]
The system startup stage on embedded Linux system starts by executing the firmware / program on the on-chip boot ROM, which then load bootloader / operating system from the storage device like eMMC, eUFS, NAND flash, etc. [5] The sequences of system startup are varies by processors [5] but all include hardware initialization and system hardware ...
Packet flow paths in the Linux kernel. XDP bypasses the networking stack and memory allocation for packet metadata . The idea behind XDP is to add an early hook in the RX path of the kernel, and let a user supplied eBPF program decide the fate of the packet.
In BASIC programs, chain loading is the purview of the CHAIN statement (or, in Commodore BASIC, the LOAD statement), which causes the current program to be terminated and the chained-to program to be loaded and invoked (with, on those dialects of BASIC that support it, an optional parameter specifying the line number from which execution is to ...
A rough version of the scheduler was published on the Linux Kernel Mailing List by Axboe in January 2002. [ 2 ] Measurements have shown that the deadline I/O scheduler outperforms the CFQ I/O scheduler for certain multi-threaded workloads.
IPVS: an advanced IP load balancing software implemented inside the Linux kernel. The IP Virtual Server code is merged into versions 2.4.x and newer of the Linux kernel mainline. [1] KTCPVS: implements application-level load balancing inside the Linux kernel, as of February 2011 still under development. [2]
On Linux, tracepath is a utility similar to traceroute, with the primary difference of not requiring superuser privileges. [ 12 ] Cisco 's implementation of traceroute also uses a sequence of UDP datagrams, each with incrementing TTL values, to an invalid port number at the remote host; by default, UDP port 33434 is used.
LoadRunner is a software testing tool from OpenText.It is used to test applications, measuring system behavior and performance under load.. LoadRunner can simulate millions of users concurrently using application software, recording and later analyzing the performance of key components of the application whilst under load.
