Bananymous dbdefa0f4a LibC: Implement pthread cancelation 
This code is not tested at all but it looks correct xD
 2025-06-01 13:48:03 +03:00
Bananymous 56fdf6002c Kernel/LibC: Implement pthread_kill 2025-06-01 13:48:03 +03:00
Bananymous c957f1ddca LibC: Cleanup pthread code and add some pthread_attr functions 
errno, pthread cleanup and pthread id are now stored in uthread. This
allows using these without TLS

Bananymous b1065fa01d Kernel/LibC: Add ppoll syscall and fix poll 
poll is now using its own syscall instead of wrapping aroung pselect.
This adds less overhead on top of poll and adds support for POLLHUP

Bananymous 8ff9c030bf Kernel: Add better termios support 
I'm not sure if this is correct but at least it's better than before :)

Bananymous 692ba43182 Kernel: Fix spinlock bugs found by the new spinlock security 2025-06-01 13:48:03 +03:00
Bananymous 6542a037df Kernel: Make spinlocks more safe 
Kernel now makes sure thread is not holding any spinlocks when it tries
to lock a mutex or yield. Spinlocks are supposed to be only used for
short times without the possibility of yielding
 2025-06-01 13:48:03 +03:00
Bananymous 9f4b451501 Kernel: Fix epoll deadlock 
If epoll_wait and epoll_notify were called at the same time, there was a
possible deadlock when epoll was confirming the event from the inode

pipe now sends SIGPIPE and returns EPIPE when writing and no readers are
open

Don't fail early if the first device is not the one we are looking for
 2025-05-28 03:10:01 +03:00
Bananymous 7f04b2c96c Kernel: Fix E1000 interrupt handling 
E1000 does not support MSI-X and thus does not generate RxQ0 interrupts.

Bananymous 0e0d7016b3 Kernel: Rename has_hangup -> has_hungup 2025-05-17 12:39:23 +03:00
Bananymous 553c76ab0f Kernel: Add locking to inode's epoll list 
This was prone to crashing :)
 2025-05-17 12:36:36 +03:00
Bananymous d1bb72f6fb Kernel: Don't allow CPU load printing underflow 2025-05-13 10:19:13 +03:00
Bananymous 1bcd1edbf5 Kernel/LibC: Implement basic epoll 
This implementation is on top of inodes instead of fds as linux does it.
If I start finding ports/software that relies on epoll allowing
duplicate inodes, I will do what linux does.

I'm probably missing multiple epoll_notify's which may cause hangs but
the system seems to work fine :dd:

Bananymous 9ff9d679e9 Kernel: Fix text mode cursor 
Apparently text mode renders cursor in the *foreground* color. My
current clear function used the same color for foreground and background
making the cursor effectively invisible.

Also cursor hiding is now done by moving the cursor off bounds (0, height)
some website I read said this to be valid even on VGA compatible cards
without disable bit.

Bananymous 9f3f8f950a Kernel: Add better panic message for failed shutdown 
ACPI shutdown does not work on the web emulator and running `poweroff`
crashes on `ASSERT_NOT_REACHED()`.

Bananymous 418678466c Kernel: Fix text mode palette 
ANSI and text mode color indices are not in the same order
 2025-04-23 23:07:47 +03:00
Bananymous 9f4cb5c4dd Kernel: Make pseudo terminals not overwrite old data 
If pseudo terminal buffer was filled, old implementation would overwrite
old data. This is bad if producer is capable of producing more data than
consumer can handle.
 2025-04-23 22:03:53 +03:00
Bananymous a8edb8870e Kernel: Add support for 8bit and 24bit ANSI SGR 2025-04-23 22:03:53 +03:00
Bananymous dabc3c6cc4 Kernel: Don't wrap cursor immediatly at cols() 
This prevents unwanted scrolling when writing to bottom right cell
 2025-04-23 22:03:53 +03:00
Bananymous cc7c1ad30d Kernel: Add per terminal palette for TerminalDriver 
This allows better color approximation on text mode and in future will
allow user to possibly change the palette
 2025-04-23 18:44:37 +03:00
Bananymous 35b3c3c98c Kernel: Fix scheduler load balancing 
I was not updating the current queue of the thread which lead to blocked
threads think they were in run queue
 2025-04-23 08:09:51 +03:00
Bananymous 20e17a28cf Kernel: Fix \b handling 
Don't clear the character, only move cursor backwards
