3817f5f619 Kernel+LibC: Add a DebugLogDevice that forwards everything to I/O port 0xe9. 
This is then used to implement the userspace dbgprintf() in a far more
efficient way than what we had before. :^)

a58d7fd8bb Kernel: Get rid of Kernel/types.h, separate LinearAddress/PhysicalAddress. 2019-04-06 14:29:29 +02:00
Andreas Kling
ec7817af37 Kernel: Spawn /bin/Taskbar on startup. 
I think it's good enough now to be there by default. :^)

b9738fa8ac Kernel: Move VM-related files into Kernel/VM/. 
Also break MemoryManager.{cpp,h} into one file per class.

ab43658c55 Kernel: Move devices into Kernel/Devices/. 2019-04-03 12:36:40 +02:00

9fca94269e Kernel: Move TTY-related files into Kernel/TTY/. 2019-04-03 12:28:45 +02:00

f9864940eb Kernel: Move FS-related files into Kernel/FileSystem/ 2019-04-03 12:25:24 +02:00

ee4d7c18c8 Kernel: Use a multiboot header instead of a convoluted two-part bootloader. 
The old bootloader was hilariously complicated, requiring a floppy disk with
the kernel on it, and a hard drive with the file system. This patch removes
the floppy disk from the equation and replaces it with a multiboot header.
This means the kernel can now be booted with qemu-system-i386 -kernel kernel

750d79dcaf Kernel: Initialize the CPU to allow SSE on startup. 
I still need to add support for SSE to the context switching code, but now
at least one process can use it.

239c0bd6a6 Kernel: Make block() and yield() automatically call Scheduler::yield(). 
This exposed some places we were accidentally doing a double yield().
 2019-03-24 01:52:10 +01:00
Andreas Kling
60d25f0f4a Kernel: Introduce threads, and refactor everything in support of it. 
The scheduler now operates on threads, rather than on processes.
Each process has a main thread, and can have any number of additional
threads. The process exits when the main thread exits.

This patch doesn't actually spawn any additional threads, it merely
does all the plumbing needed to make it possible. :^)

9120b05a40 Rename DNSLookupServer => LookupServer. 2019-03-20 04:26:30 +01:00
Andreas Kling
0e4a1936ca LibC: Implement gethostbyname() by talking to the DNSLookupServer. 
We now talk to the lookup server over a local socket and it does the lookup
on our behalf. Including some retry logic, which is nice, because it seems
like DNS requests disappear in the ether pretty damn often where I am.

35098cbde1 Kernel: Add a NetworkTask and a received network packet queue. 
It will be easier to deal with incoming packets in a separate task.
 2019-03-11 12:43:45 +01:00
Andreas Kling
97664fad60 Kernel: A bunch of hacking towards initial Ethernet support. 2019-03-10 20:59:23 +01:00
Andreas Kling
405413c354 Kernel: Start adding support for E1000 network adapters. 2019-03-10 15:25:33 +01:00
Andreas Kling
7d1142c7d9 Make it possible to sort a GTableModel by column+order. 
This is accomplished by putting a GSortingProxyTableModel between the model
and the view. It's pretty simplistic but it works for this use case. :^)

a738b5cb69 TextEditor: Open an empty document by default. 2019-03-07 17:15:59 +01:00
Andreas Kling
9158de6c41 Begin working on a graphical TextEditor. 
It's gonna be a wrapper around a new GTextEditor widget so I can easily
reuse the functionality anywhere I need it. :^)
 2019-03-07 00:31:06 +01:00
Andreas Kling
166aadc4e1 ProcessManager: Start working on a graphical process manager. 
I need a table view widget for this thing, so I'm also using this to
prototype a model/view thingy.

2cfcbdc735 AK: Add Retained<T>, like RetainPtr, but never null. 
Also use some Clang attribute wizardry to get a warning for use-after-move.

d4973842c9 Kernel: Run the sync daemon once every second. 
This is obviously not a final design, but 10 seconds was way too long.

ff786aa38a Spawn Launcher and FileManager on startup by default again. 
I disabled this while debugging WindowServer-in-userspace, and now that it
works fine we can bring these back up.

b6bf26430d Kernel: Have devices automagically register themselves with the VFS. 2019-02-17 10:38:07 +01:00

640360e958 Move WindowServer to userspace. 
This is a monster patch that required changing a whole bunch of things.
There are performance and stability issues all over the place, but it works.
Pretty cool, I have to admit :^)

799177feda Kernel: Make BochsVGADevice a BlockDevice and support mmapping it. 
Currently you can only mmap the entire framebuffer.
Using this when starting up the WindowServer gets us yet another step
closer towards it moving into userspace. :^)

994279d56c Kernel: Add Device base class for CharacterDevice. 
..to prepare for adding a BlockDevice class.

022f7790db Use modern C++ attributes instead of __attribute__ voodoo. 
This is quite nice, although I wish [[gnu::always_inline]] implied inline.
Also "gnu::" is kind of a wart, but whatcha gonna do.
 2019-02-15 12:30:48 +01:00

18210c606d Kernel: Remove GUIEventDevice. 
It's no longer used since all communication now happens across sockets. :^)
 2019-02-15 08:59:55 +01:00

c5a00a56c8 WindowServer: Put a clock in the top right corner of the screen. 
This way we don't even need the Clock app anymore. Very cool :^)
 2019-02-13 09:27:08 +01:00
Andreas Kling
111589a558 Kernel: Make sure processes always start out with fds 0, 1 and 2 open. 
If we don't have a TTY for the process, fall back to /dev/null.

f311d0f353 Kernel: Don't bother trying to pass environment to init's testing processes. 2019-02-12 10:19:52 +01:00

4d5fe39494 FileManager: Start building a file manager. 2019-02-09 09:22:04 +01:00

887b4a7a1a Start working on a simple Launcher app. 
Let GButton have an optional icon (GraphicsBitmap) that gets rendered in the
middle of the button if present.

Also add GraphicsBitmap::load_from_file() which allows mmap'ed RGBA32 files.
I wrote a little program to take "raw" files from GIMP and swizzle them into
the correct byte order.

71b9ec1ae0 Kernel: Add basic process priority support. 
For now, the WindowServer process will run with high priority,
while the Finalizer process will run with low priority.
Everyone else gets to be "normal".

At the moment, priority simply determines the size of your time slices.

3fc3a8d7bc Kernel: Remove some unnecessary zero initialization now that BSS is cleared. 2019-02-07 10:31:32 +01:00
Andreas Kling
6cba80510e Kernel: Add a Finalizer process to take care of dying processes. 
Instead of processes themselves getting scheduled to finish dying,
let's have a Finalizer process that wakes up whenever someone is dying.
This way we can do all kinds of lock-taking in process cleanup without
risking reentering the scheduler.

a1b63bb6d4 Bootloader: Locate the kernel's data segment and clear it. 
This was a constant source of stupid bugs and I kept postponing it because
I wasn't in the mood to write assembly code. Until now! :^)

731fc5a7c8 Kernel: Much improved BochsVGA (BXVGA) support. 
Instead of cowboy-calling the VESA BIOS in the bootloader, find the emulator
VGA adapter by scanning the PCI bus. Then set up the desired video mode by
sending device commands.

d0078b6574 Clock: Turns the clock window from guitest2 into a separate program. 
We can't not have a desktop clock app. :^)
