fio allows you to test various different IO subsystems and patterns. It can help us test and benchmark the I/O subsystems of Serenity. This port gets the fio bootstrapped and working, using the included .fio file, I have been able to test the file I/O performance already. |

Patches for fio 3.29 on SerenityOS
0001-fio-remove-non-existent-header-sys-ipc.patch
Serenity currently doesn't have a <sys/ipc.h> header, so we have to patch the include out.
0002-fio-add-serenityos-platform-support.patch
fio abstracts individual operating system support out into to an os/os-<name>.h header
where you can select which platform features are available and implement missing function
stubs for our operating system.
This patch implements basic OS support for Serenity just to get fio up and running.
0003-fio-add-serenityos-support-to-configure.patch
This patch implements targetos detection for serenity, and also disables shared memory support automatically for serenity, as it's not currently supported.
0004-fio-disable-rdtsc-support-for-serenityos.patch
This patch disables the function which uses rdtsc to get the current clock time,
as that instruction isn't allowed to be called from user space by serenity.
If you did attempt to call it you would trip a segfault.
