+Binary packages
+---------------
+
+Debian:
+Starting with Debian "Squeeze", fio packages are part of the official
+Debian repository. http://packages.debian.org/search?keywords=fio
+
+Ubuntu:
+Starting with Ubuntu 10.04 LTS (aka "Lucid Lynx"), fio packages are part
+of the Ubuntu "universe" repository.
+http://packages.ubuntu.com/search?keywords=fio
+
+SUSE:
+Pascal Bleser <guru@unixtech.be> has fio RPMs in his repository for SUSE
+variants, you can find them here:
http://linux01.gwdg.de/~pbleser/rpm-navigation.php?cat=System/fio
+Red Hat, CentOS & Co:
Dag Wieërs has RPMs for Red Hat related distros, find them here:
-
http://dag.wieers.com/rpm/packages/fio/
+Mandriva:
Mandriva has integrated fio into their package repository, so installing
on that distro should be as easy as typing 'urpmi fio'.
+Solaris:
+Packages for Solaris are available from OpenCSW. Install their pkgutil
+tool (http://www.opencsw.org/get-it/pkgutil/) and then install fio via
+'pkgutil -i fio'.
+
+Windows:
+Bruce Cran <bruce@cran.org.uk> has fio packages for Windows at
+http://www.bluestop.org/fio .

Building
--------
-Just type 'make' and 'make install'. If on FreeBSD, for now you have to
-specify the FreeBSD Makefile with -f and use gmake (not make), eg:
+Just type 'make' and 'make install'.
-$ gmake -f Makefile.Freebsd && gmake -f Makefile.FreeBSD install
-
-Likewise with OpenSolaris, use the Makefile.solaris to compile there.
-The OpenSolaris make should work fine. This might change in the
-future if I opt for an autoconf type setup.
+Note that GNU make is required. On BSD it's available from devel/gmake;
+on Solaris it's in the SUNWgmake package. On platforms where GNU make
+isn't the default, type 'gmake' instead of 'make'.
If your compile fails with an error like this:
based distros, it's typically called libaio-devel.
+Windows
+-------
+
+On Windows Cygwin (http://www.cygwin.com) is required with at least
+devel/gcc4 and devel/make installed in order to build fio, and
+admin/cygrunsrv to run it. You can also install devel/git to fetch/update
+the source files. To create an MSI installer package put a copy of Cygwin
+in os\windows\fio, install WiX 3.6 from http://wix.sourceforge.net/releases/
+and run dobuild.cmd from the os/windows directory.
+
+Before running fio you'll need to have a copy of cygserver running. Run
+"/usr/bin/cygserver-config" from an elevated Cygwin shell (i.e. launch the
+Cygwin shell under the Administrator account) to configure it. Once
+configured, run "net start cygserver" to start it, or type
+"/usr/sbin/cygserver &" in the Cygwin shell to start a local copy.
+
+If fio exits with the message "Bad system call" it normally means that
+Cygserver isn't running.

each job file will be regarded as a separate group and fio will stonewall
its execution.

+The --readonly switch is an extra safety guard to prevent accidentally
turning on a write setting when that is not desired. Fio will only write
if rw=write/randwrite/rw/randrw is given, but this extra safety net can
be used as an extra precaution. It will also enable a write check in the

Platforms
---------
-Fio works on (at least) Linux, Solaris, and FreeBSD. Some features and/or
-options may only be available on some of the platforms, typically because
-those features only apply to that platform (like the solarisaio engine, or
-the splice engine on Linux).
+Fio works on (at least) Linux, Solaris, AIX, OSX, NetBSD, Windows and FreeBSD.
+Some features and/or options may only be available on some of the platforms,

Some features are not available on FreeBSD/Solaris even if they could be
implemented, I'd be happy to take patches for that. An example of that is
appreciated. There's a lot of value in having the same test/benchmark tool
available on all platforms.
+Note that POSIX aio is not enabled by default on AIX. If you get messages like:
+
+ Symbol resolution failed for /usr/lib/libc.a(posix_aio.o) because:
+ Symbol _posix_kaio_rdwr (number 2) is not exported from dependent module /unix.
+
+you need to enable POSIX aio. Run the following commands as root:
+
+ # lsdev -C -l posix_aio0
+ posix_aio0 Defined Posix Asynchronous I/O
+ # cfgmgr -l posix_aio0
+ # lsdev -C -l posix_aio0
+ posix_aio0 Available Posix Asynchronous I/O
+
+POSIX aio should work now. To make the change permanent:
+
+ # chdev -l posix_aio0 -P -a autoconfig='available'
+ posix_aio0 changed
