In January 2018, the Meltdown vulnerability was published, known to affect Intel's x86 CPUs and ARM Cortex-A75. [22] [23] It was a far more severe vulnerability than the KASLR bypass that KAISER originally intended to fix: It was found that contents of kernel memory could also be leaked, not just the locations of memory mappings, as previously thought.
It supports hardware performance counters, tracepoints, software performance counters (e.g. hrtimer), and dynamic probes (for example, kprobes or uprobes). [4] In 2012, two IBM engineers recognized perf (along with OProfile ) as one of the two most commonly used performance counter profiling tools on Linux.
The Linux kernel received a patch for CFS in November 2010 for the 2.6.38 kernel that has made the scheduler "fairer" for use on desktops and workstations. Developed by Mike Galbraith using ideas suggested by Linus Torvalds, the patch implements a feature called auto-grouping that significantly boosts interactive desktop performance. [6]
Phoronix is a technology website that offers information on the development of the Linux kernel, product reviews, interviews, and news regarding free and open-source software by monitoring the Linux kernel mailing list or interviews. Phoronix was started in June 2004 by Michael Larabel, who currently serves as the owner and editor-in-chief.
The criticism of Linux focuses on issues concerning use of operating systems which use the Linux kernel. While the Linux-based Android operating system dominates the smartphone market in many countries, [ 1 ] [ 2 ] and Linux is used on the New York Stock Exchange and most supercomputers , [ 3 ] it is used in few desktop and laptop computers.
