Kernel: namespace and function renames
...
MMU moved to namespace kernel
Kernel::Memory::Heap moved to just Kernel
MMU::map_{page,range} renamed to identity_map_{page,range}
Add MMU::get_page_flags

Kernel: Usespace programs are now ran through ELF files
...
only 64 bit elf files are supported for now.

Kernel: kmalloc does not dump stack trace
...
dump_stack_trace() page faults and i dont feel like debugging this
now :)
2023-04-21 13:45:13 +03:00
9c506ef85b
Kernel: Stack pointer is validated when updated
...
This allows us not to fail stack pointer when in syscall since
interrupts use their own stack
2023-04-21 10:40:24 +03:00
b1c7af38d0
Kernel: Add barebones per process virtual addresses
...
We now assign every (userspace) process its own MMU which we load
in scheduler. This allows every process to have separate virtual
address space.
This is very hackish implementations but it works for now
2023-04-20 00:45:41 +03:00
0030f035be
Kernel: Rename MMU::{un,}allocate... to MMU::{un,}map
...
This is more appropriate name for the behaviour :D
2023-04-19 21:50:30 +03:00

Kernel: We now launch Shell again on boot
...
Adding this just before push :D
2023-04-19 00:41:24 +03:00
a9a15ea2c0
Kernel: init2 is now launched as a process instead of thread
...
Also only process can now add threads to scheduler. Nobody should
have raw access to scheduler and everything should be through
Process::current() or irqs (reschedules)
2023-04-19 00:39:06 +03:00
d63716db96
Kernel: Process is not reference counted any more
...
This was not necessary and it made things needlessly complicated
2023-04-19 00:34:18 +03:00
c5347e6707
Kernel: Reorder boot initialization
...
We now create the TTY as soon as possible so we can show console
output without serial port.
2023-04-18 10:18:15 +03:00

These are still allocated on the kernel memory
2023-04-12 17:52:36 +03:00

Kernel: Shell now somewhat functions again
...
I will not be fixing the shell implementation until I get to
userspace
2023-04-05 11:37:41 +03:00
4f522d337a
Kernel: Add partial support for shell
...
We don't handle arrow keys, and the tty does not know how to clear
the screeen :D
2023-04-05 01:30:58 +03:00
af0979ec32
Kernel: Process can now initialize stdio
...
This allows the use of the fds STD{IN,OUT,ERR}_FILENO
2023-04-05 01:10:25 +03:00
7f95444bb5
Kernel: Start work on making tty a file
...
TTY is now a file that you can read from/write to. I still have
to port shell to use this new interface
2023-04-05 00:56:09 +03:00

...
Shell reads keyboard through /dev/input :)
2023-03-29 11:50:46 +03:00
fa8e921ee8
Kernel: Rework the whole input system
...
We now use Device abstraction that will allow us to provide devices
to userspace through /dev. Currently Shell reads from first and only
device (it being PS/2 Keyboard).
2023-03-29 03:05:16 +03:00
c7286396d8
Kernel: Move ACPI to its own file
2023-03-27 17:30:45 +03:00

Kernel: Add basic mounting to VFS.
2023-03-19 05:51:25 +02:00
1a26a318a4
Kernel: Rework filesystem reading
...
We now read from a filesystem to user provided buffer.
Read sizes are determined by read call.
You should now get file descriptors and do reading through Process::current()
2023-03-17 21:18:41 +02:00
1b7625581d
Kernel: Add basic concept of Processes
...
We now create Shell as a process that has its own threads
2023-03-16 12:17:04 +02:00

Kernel/Userspace: Start initial work on userspace and syscalls
2023-03-13 15:32:46 +02:00
af854ec9e1
Kernel: Thread creation now takes void(*)() as entry and void* as data
...
This simplifies threading for the future and gets rid of (undefined?)
cast of member function pointer to address
2023-03-09 15:33:42 +02:00
8940ff8002
Kernel: You don't have to check whether VFS is initialized or not
...
VFS now returns Error when attempting to traverse inodes if it did
not find root partition
2023-03-09 02:31:24 +02:00

BAN: Formatter now uses perfect forwarding on its arguments
2023-03-08 21:31:26 +02:00
d90aba0963
Kernel: Create CriticalScope and fix kmalloc
...
This disables interrupts for the current scope and restores them
after the scope. This is used in kmalloc, since scheduler might
call into kmalloc/kfree, but deadlock if some thread is currently
trying to allocate. This allows us to use kmalloc in Scheduler.
2023-03-08 13:55:53 +02:00

Kernel: Add lock to Disk reads before I forget
2023-02-26 03:48:11 +02:00
ee5d02aa70
Kernel: Rewrite basically all current disk io stuff
...
This is a big commit that was kinda hard to split to smaller ones.
Essentially we now look at all the mass storage devices from PCI
and initialize (P)ATA devices. This doesn't provide any more functionality
but better abstractions and everything doesn't have to be on its old
default port that might be different for modern computers.
2023-02-26 03:00:29 +02:00

Kernel: Add prefs font for terminal output before file system
2023-02-23 01:22:50 +02:00
a4980acc88
Kernel: Fonts can now be parsed from the filesystem and set to terminal
...
We currently dont have a fallback font if we cannot get to filesystem
initialization, but that will come later. I can't test on real hardware
for this reason.
2023-02-22 22:29:31 +02:00

Kernel: Sleep now actually sleeps and allows idling
2023-02-19 18:52:25 +02:00

We have a basic PATA driver (for reading) and gpt parser.

This was a mess since I didn't know which to use but now I decided
to go with snake_case :)

6a9d60a8fb
Kernel: Implement somewhat functioning multithread support
...
This still uses only a single cpu, but we can now have 'parallelization'
This seems to work fine in qemu and bochs, but my own computer did not
like this when I last tried.
I have absolutely no idea how multithreading should actually be
implmemented and I just thought and implemented the most simple one I
could think of. This might not be in any way correct :D
2023-02-01 01:53:35 +02:00
9c31790359

...
This makes all debug output to appear on the TTY
2023-01-25 22:51:42 +02:00
c0bc002ac6
Kernel: Move debug printing to its own file
...
It didn't make sense that dprint was defined in Serial.h.
We also now dump dprint to tty if there is no serial and tty is initialized

Kernel: Rewrite the whole VESA driver
...
We dont support vga text mode currently. I might add it later if needed.
I also removed mouse 'support' from Shell since it didn't do anything
and I didn't implement arbitary bitmap rendering to framebuffer
2023-01-23 13:21:53 +02:00
