+Mandriva:
Mandriva has integrated fio into their package repository, so installing
on that distro should be as easy as typing 'urpmi fio'.

Mailing list
------------
There's a mailing list associated with fio. It's meant for general
-discussion, bug reporting, questions - basically anything that has to
-do with fio. An automated mail detailing recent commits is automatically
-sent to the list at most daily. The list address is fio-devel@kernel.dk,
-subscribe by sending an empty email to fio-devel+subscribe@kernel.dk.

Building
--------
-Just type 'make' and 'make install'. If on FreeBSD, for now you have to
-specify the FreeBSD Makefile with -f, eg:
-
-$ make -f Makefile.Freebsd && make -f Makefile.FreeBSD install
+Just type 'make' and 'make install'.
-Likewise with OpenSolaris, use the Makefile.solaris to compile there.
-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, 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.

allocates shared structures from this pool. The pool defaults to 1024k

+Platforms
+---------
+
+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,
+typically because those features only apply to that platform (like the
+solarisaio engine, or the splice engine on Linux).
+
+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
+disk utility statistics and (I think) huge page support, support for that
+does exist in FreeBSD/Solaris.
+
+Fio uses pthread mutexes for signalling and locking and FreeBSD does not
+support process shared pthread mutexes. As a result, only threads are
+supported on FreeBSD. This could be fixed with sysv ipc locking or
+other locking alternatives.
+
+Other *BSD platforms are untested, but fio should work there almost out
+of the box. Since I don't do test runs or even compiles on those platforms,
+your mileage may vary. Sending me patches for other platforms is greatly
+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
