Bananymous 2259614640 Kernel: Remove unused function from ACPI namespace 2024-12-18 01:43:04 +02:00
Bananymous 869f4011a1 Kernel: Replace the old AML interpreter by a new, better one
The old AML interpreter was trash and did not follow value/reference
semantics at all. It was also super slow, one of my machines taking over
7 seconds to parse ACPI namespace and call _INI and _STA.

Bananymous 46d4e32510 Kenrel: Validate inode open mode on read/write syscalls 2024-12-15 20:49:12 +02:00

Bananymous 12a37500b0 Kernel: Fix triple-fault in vitual tty
This was happening when printing non-utf8 data while having virtual tty
as the debug console.

Bananymous 2d0690ae2d Kernel: Cleanup most of syscalls dealing with files 2024-12-07 05:33:04 +02:00

Bananymous 3bf57e0748 Kernel: Add . and .. entries to /proc/<pid> directories
This allows to run `cd ..` in one of these directories

Bananymous 51b6329c86 Kernel: Make backspace \b and delete 0x7F
This is what `vim` seems to expect and imo makes way more sense.

Bananymous 72d9e4c1e7 Kernel: Remove accidental debug prints from fcntl syscall 2024-12-05 17:34:32 +02:00
Bananymous 49133dce48 Kernel: Make pipe check data every 100ms
This prevents dead lock if read-end does not detect data before blocking
why write-end already notified.

Bananymous 0a5aacfd87 Kernel: Allow open with O_CREAT bypass file permission checks
call to open(path, O_CREAT|O_EXCL|O_RDWR, 0444) should open file as
read-write although file is created as read-only on filesystem.

Bananymous 2dec3a6c95 Kernel: Add some sanity checks for existanse of threads 2024-12-03 16:16:50 +02:00

I had misunderstood how these work

Bananymous e6a2f55a59 Kernel: Closing file backed mmap wont expand the file size 2024-12-03 16:12:26 +02:00
Bananymous 67e9ca56ac Kernel: Create /dev/urandom -> /dev/random symlink
Most software uses urandom instead of random so this allows it work
normally.

Bananymous 713daf6cd3 Kernel/LibC: Add support for creating hardlinks 2024-12-03 16:12:26 +02:00
Bananymous 415b20f884 LibC: Remove errno EEXISTS
I don't know why I had added this. It doesn't seem to be a thing on
either POSIX or linux. This was literally equivalent to EXIST

Bananymous d58ca5f37a Kernel/LibC: Implement symlink{,at} 2024-12-02 20:13:38 +02:00

Bananymous 4149748766 Kernel: Add missing include in ACPI headers 2024-12-01 21:32:34 +02:00
Bananymous 8dbbbc1a1a Kernel: Add command line option `readonly`
This prevents calls to write_sectors_impl and all dirty pages are always
kept in RAM.

Bananymous a6fc3cf7a6 Kernel: Clear AHCI pending interrupts
I have no idea why I did not have this in. All devices were just
constatly spamming interrupts like crazy :D

Bananymous 1941885cfd Kernel: Disable USB Mass Storage writing until I get it fixed
This prevented real hw from running for over 10-20 seconds. When first
disk sync happens after 10 secods, USB storage would enter faulty state
and not allow any io operations.

I have no idea what the problem is. If I don't send Reset command to the
USB device writing seems to work fine. I also don't think its part of
the Reset process either as reading works just fine.

Bananymous 88a86a9927 Kernel: Fix Thread destruction after sys_exit
This had undefined behaviour as Thread's (Processes's) PageTable was
destroyed before Thread had the change to destroy its own stacks that
lived on the PageTable.
2024-11-26 00:59:34 +02:00
Bananymous 48e030bca3 Kernel: Make PageTable non-copyable and non-movable
Also PageTable destructor now verifies that is has allocated something
instead of assuming paddr of 0.
2024-11-26 00:58:35 +02:00
Bananymous 793c0368f2 Kernel: Refactor USB mass storage code
Also increment command timeout to 10 seconds so commands don't timeout
when they are not supposted to :)

Bananymous 0247d47a3d Kernel: Make USBMassStorage send_scsi_command templated
This allows passing ConstByteSpan when data will not be modified

Bananymous 480368c878 Kernel: Cleanup and fix xHCI interrupt handling
Always clear EventHandlerBusy bit and remove unnecessary nesting
2024-11-22 22:19:53 +02:00
Bananymous c1d8790623 Kernel: Don't allow sending commands to halted xHCI 2024-11-22 22:19:29 +02:00
Bananymous fb1ffec5bb Kernel: Remove unused mutex from xHCI
This was preventing multiple xHCI controllers to do parallel device
initialization
2024-11-22 22:18:38 +02:00
Bananymous 1bdabe693f Kernel: Preserve RsvdP bits in xHCI controller initialization 2024-11-22 22:18:09 +02:00

Bananymous c7afd46016 Kernel: Don't log spurious interrupts
Some PCs seem to be spamming a lot of int 7
2024-11-21 20:40:29 +02:00
Bananymous 3573656244 Kernel: Make PARTUUID matching case insensitive
Case sensitivity made it super annoying to work with :)
2024-11-21 20:39:27 +02:00
Bananymous 1de6de975a Kernel: Rename cmdline UUID= to PARTUUID=
This makes more sense and behaves more like existing software.
2024-11-21 20:38:50 +02:00
Bananymous 865061b492 Kernel: Temporary fix to make tmpfs more stable
whole TmpFS will have to be rewritten at some point :)
2024-11-21 18:13:26 +02:00
Bananymous 70880636f4 Kernel: Implement basic USB Mass Storage support
I finally decided to do this :D
