Bananymous 370a958379 BuildSystem: GCC will now complain on functions with 1 KiB stack 2023-04-12 00:18:06 +03:00
Bananymous a0bd3dc54f Kernel: kmalloc now detects corruption 
Kmalloc checks if its nodes have corrupted. This was happening
because of stack overflow.
 2023-04-11 23:36:46 +03:00
Bananymous 809eb2fe3e Kernel: Mark Scheduler::start() as noreturn as appropriate 2023-04-11 23:33:20 +03:00
Bananymous 7010d8614f Kernel: kernel doesn't allocate large blocks of data on stack 
We used to allocate 1 KiB blocks on multiple places on stack. This
is a problem, since kernel stack shouldn't have to be too big
 2023-04-11 23:31:58 +03:00
Bananymous 69f13f1896 Kernel: Scheduler will panic if it encounters stack overflow 2023-04-11 23:29:21 +03:00
Bananymous bdaf7cddcb Kernel: Process now locks the mutex while modifying open files 
This allows processes to be actually removed from the list instead
of dead locking
 2023-04-11 23:28:16 +03:00
Bananymous 8d6db168d6 Kernel: remove message from BAN::Error 
We don't store the error message anymore in BAN::Error.
Instead we store a error code that can be mapped into a string.
This allows BAN::Error to only take 4 bytes instead of 128.

We should also make some kernel initialization just panic instead
of returning errors since they are required for succesfull boot
anyway.

Bananymous 2fabe1949c BAN: Move RefPtr to its own file and create New.h 
New.h contains definitions for placement new operators and
BAN::allocator and BAN::dealloctor
 2023-04-10 21:07:25 +03:00
Bananymous c660df14ec BuildSystem: Fix header copying to sysroot 
We used to copy all headers everytime to sysroot which caused
rebuild of the whole os. Now we use the cmake command
'copy_directory_if_different' which seemed to fix this issue :)
 2023-04-10 21:07:25 +03:00
Bananymous e704968f96 Kernel: Threads can now be terminated mid execution 2023-04-10 21:07:25 +03:00

Bananymous f70cd3ea77 BuildSystem: Cleanup cmake code 
The buildsystem is kind of a mess. I will be writingn build
instructions soon.
 2023-04-06 20:31:10 +03:00
Bananymous 5db5ff069a BuildSystem: you can now build the toolchain with cmake 2023-04-06 00:23:02 +03:00
Bananymous e84f613c4d Kernel: Shell now somewhat functions again 
I will not be fixing the shell implementation until I get to
userspace

Bananymous d0b1457f30 Kernel: TTY now supports clearing 2023-04-05 02:04:18 +03:00
Bananymous a423cd8bb3 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
Bananymous db076058b9 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
Bananymous a1100624bf 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
Bananymous 28e1497f88 Kernel: add virtual write function to inode 2023-04-03 20:29:07 +03:00

Bananymous 461a5774f8 Kernel: Device dev and rdev number is done more properly 
Also hd* partitions are now 1 indexed instead of 0
 2023-04-03 11:43:16 +03:00
Bananymous ebfd092075 Kernel: Cleaner partition parsing errors 2023-04-03 09:55:49 +03:00
Bananymous e322826347 Kernel: Optimize scheduler idling 
Now after each interrupt we will ask the scheduler to reschedule
if the current thread is the idle thread. This allows semaphore
unblocking to be practically instant when there is only one thread
executing.

Now disk reading is back to ~3 MB/s for single threaded process
 2023-04-03 01:51:05 +03:00
Bananymous 3998c5f955 Kernel: ATA now uses irqs instead of polling 
Reading is now much slower at ~500 kB/s it was around 3 MB/s.
This is probably mostly due semaphore blocking taking atleast
until next reschedule (1 ms itervals). This will be a problem
as long as we are using only single processor.

I could try to use {READ/WRITE}_MULTIPLE commands, but since
most of the disk reads are 2 sectors (inode block size) this
will at most double the speed.

Most efficient speed up would of course be caching disk access
data and inodes overall.
 2023-04-03 00:03:38 +03:00
Bananymous 762d22ed28 Kernel: Move ATADevice to its own file from ATAController 
The API is kinda weird since device reads/writes go from
ATADevice -> ATAController -> ATADevice
but this is for now atleast necessary since ATAController has(?)
to keep all devices from using the disks at the same time
 2023-04-02 18:26:19 +03:00
Bananymous f2362b2b78 Kernel: ATA controller waits now before read/write until disk is ready 
Qemu used to freeze on disk writes but now it seems fine
 2023-04-02 05:37:17 +03:00
Bananymous 471ac80420 BuildSystem: building for 32-bit works now 2023-04-02 05:03:17 +03:00
Bananymous e49d3c7bfe BuildSystem: We are now using cmake instead of plain make 
I have been annoyed for a while since I had to build everything
when running the os since the buildsystem was really bad.

I wanted to rewrite the whole build system and changed to using cmake

:)
 2023-04-02 04:07:27 +03:00
Bananymous 79090c2648 Kernel: cleanup includes 
I went quickly went through all files since I found some weird
includes :D

Bananymous 7a6b1c8e47 Kernel: Fix traversing back from mount points 2023-04-01 01:54:35 +03:00
Bananymous 8988ce2766 Kernel: Add inodes '.' and '..' to device manager 2023-04-01 01:33:04 +03:00
Bananymous dcde2ae6b4 Kernel: Reads return 0 bytes read at the end of device 
We used to not have any idea if we where already at the end of device.
Also fixed couple of copy-paste errors from read->write
 2023-04-01 00:55:07 +03:00

Bananymous eef3631a5a Kernel: Improve locking in Process, VFS and ATAController 
We used to block on all process access. This meant that shell
reading the keyboard input would block all VFS access making disk
accesses practically impossible. We now block only when it is
necessary :)
 2023-03-30 22:02:16 +03:00
Bananymous 88ee35165f Kernel: Thread is no longer RefCounted 
This makes developement with Scheduler much easier against compiler
optimizations. I could now remove the pragma GCC optimize stuff.
 2023-03-30 19:16:51 +03:00

Bananymous a24c2d9be2 Kernel: DeviceManager is now a 'FileSystem' so it can expose devices 
Shell reads keyboard through /dev/input :)
 2023-03-29 11:50:46 +03:00
Bananymous 7f90079ea7 Kernel: Fix keymap numlock behaviour 2023-03-29 03:18:22 +03:00
Bananymous f4b4987d43 Kernel: Remove obsolete KeyboardLayout/ 
This was used by the old input system. Currently keyboard layout is
hardcoded to finnish. But it will be reworked as something read from
the filesystem
 2023-03-29 03:09:14 +03:00
Bananymous ac094a48d6 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
Bananymous f9a0412e78 Kernel: ACPI unmap_header does not do anything 
We have to work with MMU mapping/unmapping to be user friendly
 2023-03-28 02:56:44 +03:00
Bananymous 2f8c9746e3 Kernel: Move ACPI to its own file 2023-03-27 17:30:45 +03:00
Bananymous f8a2c60c8d Kernel/BAN: move unix time conversion to BAN and add stat to Shell 2023-03-27 00:49:58 +03:00
Bananymous 770f7716a0 Kernel: Rework processes and VFS so we don't expose inodes 
Everything is now done through a file descriptor.
 2023-03-26 04:30:57 +03:00
Bananymous d67de70126 Kernel: Process::working_directory() is now thread safe 
I realized you cannot return a stirng view and it to be thread safe
 2023-03-24 01:46:25 +02:00
Bananymous 6f334756c5 Kernel: Create RecursiveSpinLock and add it to Process 
We now lock every function within Proccess, just to be sure.
Recursive lock allows us to use lock from the same thread even if
we already have the spinlock locked
 2023-03-24 01:32:35 +02:00
Bananymous 310713d203 Kernel: Lock process functions instead of the ata controller 
Process has to use locks at least on some functions so multithreaded
disk io is safe. This seemed to fix corrupted reads from disk
 2023-03-24 01:17:39 +02:00
Bananymous 7d2ab53baa Kernel: Ext2FS now does allocations better 
We only have to allocate at the beginning of the all functions and
can properly exit before any disk reads if we run out of memory.

This makes development little bit 'harder' since the {read,write}_block
user must allocate a buffer of atleast block_size bytes.

I also made disk access to cause kernel panic on error since the error
handling during file write is something I don't want to think now.
The filesystem can easily corrupt so, I feel like when disk io starts
to fail I'll come back to this.
 2023-03-23 23:22:31 +02:00
Bananymous 2152b8b95f Kernel: Add possibiliity to create empty files on Ext2 
Big rewrite for Ext2 for more easy and optimized code
 2023-03-23 22:26:06 +02:00
Bananymous 4fd21bc303 Kernel: Remove block group descriptor cache from ext2fs 
This will make improving the fs easier since we need to only update
the values on the disk
 2023-03-23 18:52:58 +02:00
Bananymous 15037bfc7a Kernel: Move get_unix_time to RTC namespace 2023-03-23 18:14:51 +02:00
Bananymous 3572e9794a BAN: Modify Span constructors to keep constness correctly 2023-03-23 14:26:03 +02:00

Bananymous 96579b88cf Kernel: Cleanup GPT parsing code 2023-03-23 11:13:14 +02:00
Bananymous 2ec18855f2 Kernel: TTY buffer is resized on font size change 
Shell also has better line wrapping. You still can't visually go
back to previous line, but atleas we now write from the beginning
of the line
 2023-03-22 02:09:22 +02:00
Bananymous b222581d18 Kernel: Reading from fd verifies that file is opened for reading 2023-03-22 01:55:58 +02:00
Bananymous a8e3ee6f19 Kernel: Ext2 directory functions now fail on invalid blocks 
Invalid blocks should only happen while writing to a file and
I think in that case we should just bail out instead of giving
you incomlete inode list or search result.
 2023-03-22 01:55:57 +02:00
Bananymous a083e588ba Kernel: cksum uses now a different crc32_table to match linux 'cksum' 2023-03-22 01:55:21 +02:00
Bananymous 9b500842a0 Kernel: Ext2 can now read from non-block-size aligned offsets 2023-03-21 19:19:17 +02:00
Bananymous b21348379f Kernel: Remove obsolete Ext2FS::ext2_root_inode() 
This was not used by anyone and the cast was wrong anyway
 2023-03-21 18:19:48 +02:00
Bananymous 633055293e Kernel: Remove for_each_block from Ext2 2023-03-21 18:14:02 +02:00
Bananymous ae9d618803 Kernel: Cleanup font parsing

Bananymous faf1b661bb Kernel: prefs font does not allocate extra buffer 2023-03-20 19:48:01 +02:00
Bananymous 22e45278a2 Kernel: Fix PC Screen font parsing 
I had misread the format and the parsing code was incorrect. I also
changed fonts to store unicode codepoints as 32 bit integers, so
every character can be represented
 2023-03-20 14:52:42 +02:00
Bananymous 43f4657566 Kernel: Font parsing uses Spans now 2023-03-20 13:35:54 +02:00

Bananymous b41491e205 Kernel: Add cksum to Shell for file read testing 
I also removed the 'using namespace BAN'
 2023-03-18 03:50:24 +02:00
Bananymous 8236598f9d Kernel: Optimize Ext2 disk reads 
We used to read whole file until we reached the asked offset.
Now we can calculate the appropriate block and read just the asked data.
 2023-03-18 03:47:59 +02:00
Bananymous 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()

Bananymous 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.

Bananymous 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.

Bananymous 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.

Bananymous d9c05b7378 Kernel: rewrite the whole kmalloc (again) 
Performance of the old kmalloc implementation was terrible.
We now use fixed-width linked list allocations for sizes <= 60 bytes.
This is much faster than variable size allocation.

We don't use bitmap scanning anymore since it was probably the slow
part. Instead we use headers that tell allocations size and aligment.

I removed the kmalloc_eternal, even though it was very fast, there is
not really any need for it, since the only place it was used in was IDT.

These changes allowed my psf (font) parsing to go from ~500 ms to ~20 ms.
(coming soon :D)
