Kernel: Add timeout for device commands on PS/2 devices
2024-01-10 12:51:24 +02:00

Kernel: KeyEvent is now well known keycode
...
Keycodes are easier to handle as you need only one keyboard layout
for keycodes. Otherwise you would need to implement keyboard layout
for every keyboard driver in every language.

Kernel: Move PS/2 command queue to controller instead of device
2024-01-09 20:00:19 +02:00
d760239748
Kernel: Do a big rewrite of PS/2 code
...
Command sending+response reading is now synchronized. This allows
bochs to properly initialize both mouse and keyboard simultaneously.
Also status register is checked EVERY time read/write to other IO
ports is performed.

Kernel: Reads from PS/2 keyboard and mouse can be terminated
2024-01-05 12:13:44 +02:00

Kernel: Update block_or_eintr API to return ErrorOr<>
2024-01-05 12:13:11 +02:00
e45b544a39
Kernel: Implement PS/2 mouse driver
...
This is realtively simple driver that queries extensions (scroll +
extra buttons) from mouse and reads mouse packages.

Kernel: Reorganize PS/2 files to their own directory
2024-01-04 12:04:45 +02:00

2024-01-04 12:04:45 +02:00

2024-01-04 12:04:45 +02:00
d2d12d5281
Kernel: validate_{string,pointer}_access now return ErrorOr<void>
...
Now that signals are only processed when returning to userspace,
address validation has to do an early return.

Kernel: Start exec by loading the ELF file. It might not exist...
2024-01-03 23:50:02 +02:00
001e95f973
Kernel: Optimize sse saving/loading
...
Only save and load sse when new thread is trying to execute sse
instruction. There is no need to do that every time we enter kernel.
2024-01-03 02:06:49 +02:00
9fa13079f2
Kernel: Implement supplementary groups
...
This code has very ugly file parsing code. I have to create API
for reading files line by line in kernel space...
This allows users to open framebuffer/input files without root.
Mounting has to be moved to userspace soon. It makes no sense to
hard code permissions for every (device) file.

2023-12-19 00:20:46 +02:00
2e858fddb5
Kernel: Remove obsolete Scheduler::is_valid_tid()
...
This function was used when processes could die at any point in time.
Now that processes can only die in known spots, we can be sure they
are not holding any locks. This allows much more performant locking.
2023-12-07 13:26:42 +02:00

Kernel: Make Inodes use the new lock
...
Also remove old lock from TTY since it can just use the one Inode
already has.
2023-12-07 13:19:12 +02:00
7c25e4ce5a
Kernel: Implement RecursivePrioritySpinLock
...
This locks won't allow locking from userspace thread if there is
kernel thread waiting to lock this.

1c78671078
Kernel: Rework all signal code
...
Signal handling code was way too complex. Now everything is
simplified and there is no need for ThreadBlockers.
Only complication that this patch includes is that blocking syscalls
have to manually be made interruptable by signal. There might be some
clever solution to combat this is make this happen automatically.

fd18071975
Kernel: Implement TerminalDriver for Framebuffer device
...
Use this new FramebufferTerminalDriver for terminal instead of the
old VesaTerminalDriver. Only drawback with this is that framebuffer
device can only be intialized after DevFS is initialized.

Kernel: ProcFS inodes reflect processes ruid/rgid
...
setgid/setuid did not change the permissions of procfs inodes. This
made Shell launched by init not appear in meminfo.

Bootloader: Implement VESA video mode query and pass it to kernel
...
Kernel now gets framebuffer from bootloader. Framebuffer dimensions
and bpp are hardcoded in bootloader, but will probably be read from
config file at some point.
