644c887594 Kernel: Move FIFO into FileSystem/ and Socket+LocalSocket into Net/. 2019-04-06 20:29:48 +02:00

ac6c7d3e19 Kernel: Use alloc_fd() more instead of walking fd list manually. 2019-04-06 14:54:32 +02:00

a58d7fd8bb Kernel: Get rid of Kernel/types.h, separate LinearAddress/PhysicalAddress. 2019-04-06 14:29:29 +02:00

9fbac66a91 Hack sync.sh script to retry umount after a short delay if it fails. 
I keep accumulated unwanted mounts because umount sometimes fails.

329cc60a92 NetworkTask: Add a combined alarm for the all network adapters. 
This way we can go back to snoozing in the receiver task and stop chewing
up the CPU. :^)

bcc00857a4 AK: Revert Eternal<T> for now since it doesn't work as intended. 2019-04-05 05:14:20 +02:00

6df5e3f51a Kernel: Build with i686-pc-serenity-g++. 
This works just fine, and now we only need one cross-compiler. :^)

ec7817af37 Kernel: Spawn /bin/Taskbar on startup. 
I think it's good enough now to be there by default. :^)

ea801a99dc Kernel: Bump per-process file descriptor limit to 128. 2019-04-03 23:48:59 +02:00

a22774ee3f Taskbar: Start working on a taskbar app. 
I originally thought I would do this inside WindowServer, but let's try to
make it as a standalone app that communicates with WindowServer instead.
That will allow us to use LibGUI. :^)

c02c9880b6 AK: Add Eternal<T> and use it in various places. 
This is useful for static locals that never need to be destroyed:

Thing& Thing::the()
{
    static Eternal<Thing> the;
    return the;
}

The object will be allocated in data segment memory and will never have
its destructor invoked.

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

a095a90b51 Kernel: Remove ancient nprocess and nblocked globals. 
These were not in sync with reality, and not used anywhere anyway.

d11b5407a3 Kernel: Get rid of the GPL elf.h and import exec_elf.h from OpenBSD. 2019-04-03 11:30:56 +02:00

17e02e7450 Move NetworkOrdered.h to AK/ since it's used in both kernel and userspace. 2019-04-02 20:04:54 +02:00

649c81a714 Kernel: Move networking related files into Kernel/Net/. 2019-04-02 19:54:38 +02:00

718bea73b3 Kernel: Add a LoopbackAdapter for talking to yourself via 127.0.0.1. 
Choosing adapter for transmit is done by adapter_for_route_to(IPv4Address).
This is just hard-coded logic right now but can be expanded to support a
proper routing table.

Also start moving kernel networking code into Kernel/Net/.

94c68dc55a Kernel: Spawn the Launcher by default. 2019-04-01 22:04:09 +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

d5a9f4596b Kernel: Add a blunt big process lock. 
We can't have multiple threads in the same process running in the kernel
at the same time, so let's have a per-process lock that threads have to
acquire on syscall entry/exit (and yield while blocked.)
 2019-04-01 20:04:29 +02:00

245c4bd7c8 Kernel: Add a bit of debug output in do_exec() to learn about thread counts. 2019-03-30 21:14:40 +01:00
Andreas Kling
73f3e05ebb Stopwatch: Print the result in decimal instead of hexadecimal. 2019-03-30 04:20:08 +01:00
Andreas Kling
0058da734e Kernel: Add Inode::truncate(size). 
- Use this to implement the O_TRUNC open flag.
- Fix creat() to pass O_CREAT | O_TRUNC | O_WRONLY.
- Make sure we truncate wherever appropriate.

e9f2cc3595 Kernel: Save/restore the SSE context on context switch. 2019-03-27 15:27:45 +01:00

44e1e7423f Kernel: Put a bunch of debug spam behind #ifdefs. 2019-03-27 15:07:12 +01:00

a2fe5f8517 Kernel: Don't disable interrupts during Process destruction. 2019-03-27 14:38:32 +01:00

d5508e5116 Ext2FS: Avoid a lot of redundant writes to inode block arrays. 2019-03-27 14:24:37 +01:00
Andreas Kling
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.

5808322556 Give the emulator testing environments 128 MB of RAM. 
I'm working on porting GCC and it needs a fair bit of memory to run.

23bb276fcd LibC: Run constructors on process startup. 
Cooperate with the compiler to generate and execute the _init_array list
of constructor functions on userspace program statup. This took two days
to get working, my goodness. :^)

75207ddffd Kernel: Load ELF executable pages lazily when possible. 
This currently only works for "normal" processes created by fork().
It does not work for create_user_process() processes spawned by the
kernel, as those are a bit special during construction.
 2019-03-27 04:01:15 +01:00

abd5931184 Kernel: Print an error when trying to load an incompatible ELF image. 2019-03-27 01:29:49 +01:00
Andreas Kling
500df578fe LibGUI+Kernel: Add a GLock class (userspace mutex.) 
It's basically a userspace port of the kernel's Lock class.
Added gettid() and donate() syscalls to support the timeslice donation
feature we already enjoyed in the kernel.

Andreas Kling
ab11f42094 Kernel: Do timekeeping manually instead of asking the RTC all the time. 
This introduces a tiny amount of timer drift which I will have to fix
somehow eventually, but it's a huge improvement in timing consistency
as we no longer suddenly jump from e.g 10:45:49.123 to 10:45:50.000.

e7c1caa2b5 Kernel: Don't hang the system on unrecoverable page fault. 
I needed this while debugging threads and now they basically work pretty
well so we can remove this. :^)
 2019-03-24 02:11:07 +01:00
Andreas Kling
239c0bd6a6 Kernel: Make block() and yield() automatically call Scheduler::yield(). 
This exposed some places we were accidentally doing a double yield().

5713c3a0cb Kernel: Fix broken destruction order for Process/Thread. 2019-03-24 01:20:35 +01:00
