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.
