Kernel compilation
==================
---
The gcc version requirements may vary depending on the type of CPU in your
-computer. The next paragraph applies to users of x86 CPUs, but not
-necessarily to users of other CPUs. Users of other CPUs should obtain
-information about their gcc version requirements from another source.
-
-The recommended compiler for the kernel is gcc 2.95.x (x >= 3), and it
-should be used when you need absolute stability. You may use gcc 3.0.x
-instead if you wish, although it may cause problems. Later versions of gcc
-have not received much testing for Linux kernel compilation, and there are
-almost certainly bugs (mainly, but not exclusively, in the kernel) that
-will need to be fixed in order to use these compilers. In any case, using
-pgcc instead of plain gcc is just asking for trouble.
-
-The Red Hat gcc 2.96 compiler subtree can also be used to build this tree.
-You should ensure you use gcc-2.96-74 or later. gcc-2.96-54 will not build
-the kernel correctly.
-
-In addition, please pay attention to compiler optimization. Anything
-greater than -O2 may not be wise. Similarly, if you choose to use gcc-2.95.x
-or derivatives, be sure not to use -fstrict-aliasing (which, depending on
-your version of gcc 2.95.x, may necessitate using -fno-strict-aliasing).

Make
----
-You will need Gnu make 3.79.1 or later to build the kernel.
+You will need Gnu make 3.80 or later to build the kernel.
Binutils
--------
your kernel. This change does, however, mean that you need a recent
release of binutils.
+Perl
+----
+
+You will need perl 5 and the following modules: Getopt::Long, Getopt::Std,
+File::Basename, and File::Find to build the kernel.
+
+
System utilities
================
Ksymoops
--------
-If the unthinkable happens and your kernel oopses, you'll need a 2.4
-version of ksymoops to decode the report; see REPORTING-BUGS in the
-root of the Linux source for more information.
+If the unthinkable happens and your kernel oopses, you may need the
+ksymoops tool to decode it, but in most cases you don't.
+In the 2.6 kernel it is generally preferred to build the kernel with
+CONFIG_KALLSYMS so that it produces readable dumps that can be used as-is
+(this also produces better output than ksymoops).
+If for some reason your kernel is not build with CONFIG_KALLSYMS and
+you have no way to rebuild and reproduce the Oops with that option, then
+you can still decode that Oops with ksymoops.
Module-Init-Tools
-----------------
--------------------
A driver has been added to allow updating of Intel IA32 microcode,
-accessible as both a devfs regular file and as a normal (misc)
-character device. If you are not using devfs you may need to:
+accessible as a normal (misc) character device. If you are not using
+udev you may need to:
mkdir /dev/cpu
mknod /dev/cpu/microcode c 10 184
udev
----
udev is a userspace application for populating /dev dynamically with
-only entries for devices actually present. udev replaces devfs.
+only entries for devices actually present. udev replaces the basic
+functionality of devfs, while allowing persistent device naming for
+devices.
FUSE
----
enable it to operate over diverse media layers. If you use PPP,
upgrade pppd to at least 2.4.0.
-If you are not using devfs, you must have the device file /dev/ppp
+If you are not using udev, you must have the device file /dev/ppp
which can be made by:
mknod /dev/ppp c 108 0
as root.
-If you use devfsd and build ppp support as modules, you will need
-the following in your /etc/devfsd.conf file:
-
-LOOKUP PPP MODLOAD
-
Isdn4k-utils
------------
To enable this new functionality, you need to:
- mount -t nfsd nfsd /proc/fs/nfs
+ mount -t nfsd nfsd /proc/fs/nfsd
before running exportfs or mountd. It is recommended that all NFS
services be protected from the internet-at-large by a firewall where
that is possible.
+mcelog
+------
+
+In Linux 2.6.31+ the i386 kernel needs to run the mcelog utility
+as a regular cronjob similar to the x86-64 kernel to process and log
+machine check events when CONFIG_X86_NEW_MCE is enabled. Machine check
+events are errors reported by the CPU. Processing them is strongly encouraged.
+All x86-64 kernels since 2.6.4 require the mcelog utility to
+process machine checks.
