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

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.

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

Bananymous 6f9dc2a9b8 Kernel/LibC: Implement `fchdir`, cleanup `chdir` and `getcwd` 2025-04-19 21:28:31 +03:00

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 :)

Bananymous 40d1d20cd6 Kernel: Move cursor handling from TTY -> TerminalDriver 2025-04-18 02:43:41 +03:00

Bananymous 554b13ac50 Kernel: Restructure terminal initialization 
This is still very ugly and will be rewritten in the future :D
 2025-04-18 01:19:59 +03:00
Bananymous 439fb57d88 Kernel: Fix ANSI CSI @ and b for VirtualTTY 2025-04-17 23:24:17 +03:00
Bananymous ac90800c3c Kernel/LibC/DynamicLoader: Implement thread local storage 
For some reason this does not work on 32 bit version, so it is disabled
on that platform. I'll have to look into it later to find the bug :)

Bananymous 4bcd3ed86f Kernel: Start working on TLS, add SYS_{SET,GET}_TLS 2025-04-15 23:31:17 +03:00
Bananymous a933fabb86 Kernel: Define constant USERSPACE_END 
This should be used for userspace generic allocations. Currently I used
KERNEL_OFFSET, but I want to limit userspace to the actual lower half of
the address space
 2025-04-15 23:31:17 +03:00
Bananymous 36baf7b0af Kernel/LibC/DynamicLoader: Update process start ABI 
We now use SysV abi for process startup

Bananymous 96767f5ca8 Kernel: Implement PCI interrupt routing 
This does not really work but I have no idea what I'm doing wrong

Bananymous 1c1fc65c7c Kernel: Add API to reserve GSI instead of irq 
This also fixes a bug with IOAPIC gsi_base != 0

Bananymous 3800d5420e Kernel: Collect created AML nodes in add_{named,alias}... 
This makes it harder to miss adding scoped objects. Before I was not
deleting all types of nodes on method return

Bananymous 088f77a226 Kernel: Add super basic support for USB keyboard LEDs 
This is very hacky but it seems to mostly work. Also for some reason
this fixed my Razer Mamba mouse????
 2025-02-11 02:18:50 +02:00
Bananymous 4dd6c85df2 Kernel: Fix USB keyboard Scroll lock 
I was using 8 bit modifier and ScrollLock bit does not fit this. Also I
was not generating ScrollLock keypresses

Bananymous d0452a3510 Kernel: Fix xHCI controller destruction 
Port updater task was not actually able to exit without a kernel panic.
This patch makes controller wait until port updater exits itself :D

Bananymous 22b32a0fe5 Kernel: Expose PCI interrupt mechanism from PCIDevice 2025-02-10 22:57:25 +02:00
Bananymous ad143c184f Kernel: Add basic support for USB hubs 
This is still buggy and some hubs lead to usb transaction errors. I'll
have to debug this but this shouldn't prevent any already working device
from working

Bananymous 267fdf9fa1 Kernel: Remove storage devices after unplugging them 2025-02-07 18:04:54 +02:00
Bananymous 7de689055c Kernel: Pass xHCI device information in structs 
This makes code more readable and extendable
 2025-02-06 23:18:14 +02:00
Bananymous 63b15a8855 Kernel: Rename USB initialize_endpoint -> configure_endpoint 
This makes more sense as the USB command is CONFIGURE_ENDPOINT

Also configure_endpoint can be called multiple times on the same
endpoint. There was no reason to limit this to only one call.

Bananymous a2a7302964 Kernel: Make sure USB class driver is deinitialized before xhci device 2025-02-06 22:00:26 +02:00
Bananymous 6768a18475 Kernel: Don't parse xHCI custom slot_types 
xHCI spec mandates that slot_type for USB protocol is 0.
 2025-02-06 21:41:44 +02:00
Bananymous 242ed4a3c2 Kernel: Remove support for custom xHCI speed_ids 
This gets really weird with hubs and I don't think even linux handles
them.

Bananymous f9b70d1b5b Kernel: Don't enter infinite loop on unexpected serial behaviour 2025-02-06 20:59:17 +02:00

Bananymous ee078fc638 Kernel: Fix fd status/descriptor flag handling 
I was not sharing status and offset on fork and I was sharing descriptor
flags on dup/dup2

Bananymous 9893c90e74 Kernel: Remove SYS_DUP and implement it using fcntl F_DUPFD 2025-01-17 19:29:47 +02:00
