2013-12-17 14:30:26 +01:00
ef53864d36
dispd: Wait for console rendering to finish.
...
This prevents a race condition where the console may still be rendering,
but the process may be able to get data on the screen faster, which results
in visual corruption as the two race.

3b35dad9f7
Add AT_REMOVEFILE flag to unlinkat(2).
...
This allows unlinkat(2) to delete files and directories in the same call,
which is useful for the implementation of remove(3).
2013-12-17 14:30:25 +01:00

2013-12-17 14:30:25 +01:00
f843e15666
Add truncateat(2).
...
Linux doesn't have this, but since I do truncate(2) in the kernel, it would
be more consistent to do it 'at'-style. (I will remove truncate(2) from the
kernel and let libc call truncateat(2) soon anyway).

Use libgcc.
2012-12-14 14:13:36 +01:00
838992c3d8
Don't build libmaxsi.a.
...
This should just about remove most of the old and deprecated (and now
obsolete) Maxsi:: API. Of course, large parts of libc still suffer from
its poor design, but I'll get around to fix that eventually.
2012-12-14 14:13:35 +01:00

2012-12-14 14:13:34 +01:00
b685b7a9eb
Don't include Maxsi:: API in kernel.cpp.
...
Since kernel.cpp is intended to be an example of the current best coding
practices within the Sortix kernel, and the Maxsi:: API is deprecated and
is being removed, it should rather use the nice C standard library.
2012-12-14 14:13:34 +01:00
0437d75147
Remove libmaxsi stddef.h and stdarg.h.
...
These are provided by the cross compiler.
2012-12-14 14:13:34 +01:00

Remove kernel platform.h dependency on libmaxsi platform.h.
...
This reduces the dependence on libmaxsi with the aim that the Maxsi:: api
can be removed and replaced with the standard C library.

Correct usage of deprecated nat and byte data types.

2012-09-09 22:58:18 +02:00
da7f10269d

Fix NULL deference if no ATA bus is present.
2012-09-09 13:15:33 +02:00
b9b697f2cb
Implement proper W* error codes in sys/wait.h and kernel.
...
Note that signals can't really kill a process at this time.
2012-09-09 12:21:39 +02:00
b0807e8c7a
Fix reading /dev/video/fb causing a write instead.
...
This really fucks stuff up.
2012-09-08 19:40:22 +02:00

Implement WNOHANG in waitpid(2).
2012-09-08 19:19:31 +02:00

Don't deliver signals to zombies.
2012-09-08 19:15:56 +02:00

2012-09-08 18:45:53 +02:00
17a93359dd
Add . and .. support to kernel filesystems.
...
This makes the hack in ls(1) not needed and is hence removed.
2012-09-08 18:45:52 +02:00
118fc9ce9a
The lfb text buffer class now uses the correct cursor color.
2012-09-08 18:45:52 +02:00
755e855c08
Renamed sforkr(2) to tfork(2).
...
It's a much better name if you think of it as task-fork or thread-fork in the
sense that it either modifies this task or creates a new one. This call will
be used to provide user-space threads as well as fork(2).
2012-09-08 18:45:52 +02:00
7d39906acc
Added support for saving FPU registers upon context switch.
...
This code uses the cr0 task switched bit to disable the FPU upon task
switch, which allows the kernel to delay copying the registers until
another task starts using them. Or better yet, if no other thread actually
uses the registers, then it won't need to do any copying at all!
2012-09-08 18:45:52 +02:00
93bb4f992b
Added support for floating point numbers.
...
Note that the scheduler does not load/restore floating point numbers yet
upon task switching. This means only one task can use floating point numbers
at the same time without the risk of race conditions.
Note that this enables SSE in 32-bit x86 platforms - but not all models
have such support, which limits which computers Sortix works on. Ideally, we
should detect what features are available on the computer at runtime and
enable/disable the proper kernel support. This is not a problem on x86_64.
