Bananymous a945d19750 Kernel: Partially fix PCI PIN interrupt routing 
Don't fail early if the first device is not the one we are looking for

Bananymous 7f04b2c96c Kernel: Fix E1000 interrupt handling 
E1000 does not support MSI-X and thus does not generate RxQ0 interrupts.

Bananymous 553c76ab0f Kernel: Add locking to inode's epoll list 
This was prone to crashing :)

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()`.
 2025-04-25 01:52:33 +03:00
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

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
 2025-04-23 06:33:11 +03:00
Bananymous 28bf2d6374 Kernel/Terminal: Add support for ANSI DSR 2025-04-23 06:14:56 +03:00
Bananymous 8a00b53050 Kernel/Terminal: Fix ANSI SGR m for multiple values 2025-04-23 05:29:22 +03:00
Bananymous b853d29992 Kernel: Fix unix domain socket close detection 2025-04-22 08:36:44 +03:00
Bananymous f8e3ae0525 Kernel: Fix deadlock caused by multithreading 
This allows multiple threads to concurrently call the most common
blocking syscalls:
- read
- write
- accept
- connect
- sendto
- recv
- pselect

This prevents a dead lock when for example process is waiting on a pipe,
but unable to write to it since process is locked.

This is the beginning of starting to remove processes own lock from
syscall and locking only necessary parts.

Bananymous c790bad667 Kernel: Make OpenFileDescriptorSet thread safe 
Also this allows concurrent calling of read/write/send/recv
 2025-04-22 04:31:18 +03:00
Bananymous d54489bbcb Kernel: Implement MemoryRegion pinning 
This allows process to pin a MemoryRegion into users memory space for
syscall duration without allowing user to munmap the region.
 2025-04-22 04:30:07 +03:00
Bananymous 808c97020a Kernel/LibC: Implement SA_RESTART 
I have been thinking how to do this for a long time but I finally
figured out a semi-clean way
 2025-04-22 02:42:44 +03:00
Bananymous 107b31a0b5 Kernel: Fix E1000{,E} driver for older qemu versions 
This patch adds clearing of *Interrupt Cause Registers*, which allows
older qemu versions to send new interrupts. Apparently this is not
needed on newer releases.

Bananymous 201d752850 Kernel: Allow pipe to write partial data 
This allows potential blocking
 2025-04-19 00:39:42 +03:00
Bananymous 63b3d9875d Kernel: Fix `Thread::block_with_eintr*` functions 
I was using wrong block function, `block_with_timeout` instead of
`block_with_wake_time`. This caused functions to block way too long and
caused a lot of hangs.

indices.

Bananymous 9258c73484 Kernel: Optimize VTTY cursor rendering 
cursor is now only updated once after all consecutive `putchar`s are
handled.

Bananymous 7c6966a9c4 Kernel: Add support for text mode terminal 
This probably won't be used at all but it was so simple and made me do
really nice refactorings so i decided to add it :)
