6 This is a virtual file system providing information about the status
7 of the system. "Virtual" means that it doesn't take up any space on
8 your hard disk: the files are created on the fly by the kernel when
9 you try to access them. Also, you cannot read the files with older
10 version of the program less: you need to use more or cat.
13 information about what the different IRQs are used for at the moment
15 that are used by the attached devices to gain the CPU's attention --
17 to use the same IRQ). The program procinfo to display some
18 information about your system gathered from the /proc file system.
20 Before you can use the /proc file system, it has to be mounted,
21 meaning it has to be given a location in the directory hierarchy.
22 That location should be /proc. A command such as "mount -t proc proc
23 /proc" or the equivalent line in /etc/fstab does the job.
25 The /proc file system is explained in the file
26 <file:Documentation/filesystems/proc.rst> and on the proc(5) manpage
30 programs depend on this, so everyone should say Y here.

72 If the elfcore hdr is allocated and prepared by the dump kernel
73 ("2nd kernel") instead of the crashed kernel, RAM provided by memory
74 devices such as virtio-mem will not be included in the dump
75 image, because only the device driver can properly detect them.
77 With this config enabled, these RAM ranges will be queried from the
78 device drivers once the device gets probed, so they can be included
79 in the crash dump.

89 The sysctl interface provides a means of dynamically changing
90 certain kernel parameters and variables on the fly without requiring
91 a recompile of the kernel or reboot of the system. The primary
93 modifiable sysctl entries will be generated beneath the
94 /proc/sys directory. They are explained in the files
95 in <file:Documentation/admin-guide/sysctl/>. Note that enabling this
96 option will enlarge the kernel by at least 8 KB.
