The jsix Operating System
|
||||||
|
=========================
|
||||||
|
Introduction
|
||||||
|
------------
|
||||||
|
|
||||||
|
**jsix** is a custom multi-core x64 operating system being built from scratch,
|
||||||
|
supporting modern [#]_ Intel or AMD CPUs, and UEFI firmware. It was initially
|
||||||
|
created out of a desire to explore UEFI and to explore what's possible with a
|
||||||
|
microkernel architecture on modern 64-bit architectures.
|
||||||
|
|
||||||
|
Most of jsix is written in C++ (C++17, using `LLVM <https://llvm.org>`_), but
|
||||||
|
you'll also find some assembly (in `NASM <https://nasm.us>`_ syntax) and Python
|
||||||
|
for development tooling.
|
||||||
|
|
||||||
|
jsix can be found `on GitHub <https://github.com/justinian/jsix>`_, and is
|
||||||
|
released under the terms of the `MPL 2.0 <https://mozilla.org/MPL/2.0/>`_.
|
||||||
|
|
||||||
|
.. admonition:: A note on the name
|
||||||
|
|
||||||
|
This kernel was originally named Popcorn, but I have since discovered that
|
||||||
|
the Popcorn Linux project is also developing a kernel with that name,
|
||||||
|
started around the same time as this project. So I've renamed this kernel
|
||||||
|
jsix as an homage to L4, xv6, and my wonderful wife.
|
||||||
|
|
||||||
|
The name jsix is always styled *jsix* or ``j6``, never capitalized.
|
||||||
|
|
||||||
|
.. [#] jsix aims to support amd64 (x86_64) CPUs released in the last 10 years.
|
||||||
|
|
||||||
|
Current Features
|
||||||
|
----------------
|
||||||
|
|
||||||
|
The jsix kernel is quite far along now, but the userland systems are still lacking.
|
||||||
|
|
||||||
|
- Platform: |amd64|
|
||||||
|
- UEFI bootloader
|
||||||
|
- Multi-core & multi-tasking microkernel
|
||||||
|
|
||||||
|
- Work-stealing SMP scheduler
|
||||||
|
- Pluggable panic handler modules
|
||||||
|
|
||||||
|
- Capability-style object-oriented syscall API
|
||||||
|
|
||||||
|
- Custom IDL for specifying and documenting syscalls
|
||||||
|
|
||||||
|
- Virtual memory based on sharable Virtual Memory Area objects (VMAs)
|
||||||
|
- Kernel API library (libj6), also provides features built on kernel primitives:
|
||||||
|
|
||||||
|
- Channels (async stream IPC) built on shared memory and futexes
|
||||||
|
- Ring buffers via doubly-mapped pages
|
||||||
|
|
||||||
|
- Custom libc
|
||||||
|
- Runtime dynamic linker
|
||||||
|
- Init service
|
||||||
|
|
||||||
|
- Built-in VFS service for the initrd
|
||||||
|
- ELF loader
|
||||||
|
- Service-lookup protocol service
|
||||||
|
|
||||||
|
- Userland UART driver
|
||||||
|
- Userland UEFI framebuffer driver
|
||||||
|
- Userland kernel log output service
|
||||||
|
- Userland unit test runner
|

The jsix syscall interface
|
||||||
|
==========================
|
||||||
|
|
||||||
|
The jsix kernel's syscall design is based around object handles. Object handles
|
||||||
|
are also a collections capabilities, encoding certain rights over the object
|
||||||
|
they reference.
|
||||||
|
|
||||||
|
Very few syscalls in jsix can be made without some handle, and most of them are
|
||||||
|
requests to the kernel to create a given kind of object. This is analogous to
|
||||||
|
methods on an object in an object-oriented programming language.

``object`` syscalls
|
||||||
|
-------------------------
|
||||||
|
All kernel-exposed objects inherit from the base ``object`` type, so the
|
||||||
|
``object`` syscalls can be used with any object's handle.
|
||||||
|
|
||||||
|
:capabilites: ``clone``
|
||||||
|
|
||||||
|
.. cpp:function:: j6_result_t j6_object_koid (j6_handle_t self, uint64_t * koid)
|
||||||
|
|
||||||
|
Get the internal kernel object id of an object
|
||||||
|
|
||||||
|
:param self: Handle to the object object
|
||||||
|
:param koid: *[out]* Undocumented
|
||||||
|
|
||||||
|
``event`` syscalls
|
||||||
|
-------------------------
|
||||||
|
An ``event`` is a simple synchronization object. It contains up to 64 signals
|
||||||
|
that threads can wait for and signal in parallel.
|
||||||
|
|
||||||
|
:capabilites: ``signal``, ``wait``
|
||||||
|
|
||||||
|
.. cpp:function:: j6_result_t j6_event_create (j6_handle_t *self)
|
||||||
|
|
||||||
|
Undocumented
|
||||||
|
|
||||||
|

|
||||||
|
|
||||||
|
.. cpp:function:: j6_result_t j6_event_signal (j6_handle_t self, uint64_t signals)
|
||||||
|
|
||||||
|

|
||||||
|
|
||||||
|
:capabilities: ``signal``
|
||||||
|
|
||||||
|
:param self: Handle to the event object
|
||||||
|
:param signals: A bitset of which events to signal
|
||||||
|
|
||||||
|
.. cpp:function:: j6_result_t j6_event_wait (j6_handle_t self, uint64_t * signals, uint64_t timeout)
|
||||||
|
|
||||||
|
Wait for signaled events on this object
|
||||||
|
|
||||||
|
:capabilities: ``wait``
|
||||||
|
|
||||||
|
:param self: Handle to the event object
|

``mailbox`` syscalls
|
||||||
|
-------------------------
|
||||||
|
Mailboxes are objects that enable synchronous IPC via arbitrary
|
||||||
|
message-passing of tagged data and/or handles. Not as efficient
|
||||||
|
as shared memory channels, but more flexible.

|
||||||
|
|
||||||
|
Send a message to the reciever, and block until a response is
|
||||||
|
sent. Note that getting this response does not require the
|
||||||
|
receive capability.

|

|
|

|
Respond to a message sent using call, and wait for another
|
||||||
|
message to arrive. Note that this does not require the send
|

capability. A reply tag of 0 skips the reply and goes directly
|
||||||
|
to waiting for a new message.

``process`` syscalls
|
||||||

-------------------------
|
||||||
|
A ``process`` object represents a process running on the system, and allows
|
||||||
|
control over the threads, handles, and virtual memory space of that process.

|
||||||
|
object as the specified handle.
|
||||||
|
|
||||||
|
:param self: Handle to the process object
|
||||||
|
:param target: *[handle]* A handle in the caller process to send
|
||||||

``system`` syscalls
|
||||||
|
-------------------------
|
||||||
|
The singular ``system`` object represents a handle to kernel functionality
|
||||||
|
needed by drivers and other priviledged services.
|
||||||
|
|
||||||
|
:capabilites: ``get_log``, ``bind_irq``, ``map_phys``, ``change_iopl``
|
||||||

|
||||||
|
the given IRQ fires

|
||||||
|
|
||||||
|

|
||||||
|

:param iopl: The IOPL to set for this process
|
||||||
|
|
||||||
|
``thread`` syscalls
|
||||||
|
-------------------------
|
||||||
|
A ``thread`` object represents a thread of execution within a process running
|
||||||
|
on the system. The actual thread does not need to be currently running to
|
||||||
|
hold a handle to it.
|
||||||
|
|
||||||
|

``vma`` syscalls
|
||||||
|
-------------------------
|
||||||
|
A ``vma`` object represents a single virtual memory area, which may be shared
|
||||||
|
between several processes. A process having a handle to a ``vma`` does not
|
||||||
|
necessarily mean that it is mapped into that process' virtual memory space.

|
||||||
|
:capabilites: ``map``, ``unmap``, ``resize``

Non-object syscalls

-------------------
|
||||||
|
|
||||||
|
The following are the system calls that aren't constructors for objects, and

either do not require an object handle, or operate generically on handles.
