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 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.

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

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

Bananymous c7afd46016 Kernel: Don't log spurious interrupts
Some PCs seem to be spamming a lot of int 7

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.

Bananymous 865061b492 Kernel: Temporary fix to make tmpfs more stable
whole TmpFS will have to be rewritten at some point :)

Bananymous 70880636f4 Kernel: Implement basic USB Mass Storage support
I finally decided to do this :D
2024-11-21 18:08:37 +02:00
Bananymous 8054f6c618 Kernel: Wait 10 seconds to find root device
If root device is initialized asynchronously it may not be ready when
main initialization thread is finished. This patch adds searching for
root device every 500 ms for 10 seconds.

Bananymous 658ea68d04 Kernel: Check max packet size for all USB devices
Spec says that this has to be done. Most cases can be probably skipped
as I used to do, but this is less error prone and adds practically no
overhead

Bananymous 5750f87396 Kernel: Fix unaligned access in xHCI controller initialization 2024-11-21 13:46:09 +02:00
Bananymous 1253e2a458 Kernel: Add support for bulk endpoints and update endpoint API
USB device now sets its own data buffers for IN/OUT endpoints. This
allows more customization and parallelism as data buffer does not have
to be shared.

Bananymous 857b3e92f8 Kernel: Support initializing USB 3 devices 2024-11-21 13:40:16 +02:00

Bananymous 97718b4046 Kernel: Don't launch init process twice
I had accidentrally left the old init process launch in when replacing
it with the new one.

Bananymous c07fd265f0 Kernel: Add support for ATA CHS addressing and cleanup code
I thought that I had an PC without LBA support so I implement support
for CHS. Turns out that my ATA device detection was broken and was no
device on that port and initialize data was just garbage.

Now that I added CHS, I guess I should just keep it in :)

Both ATA read and write are now combined into a single function to avoid
code duplication.

Bananymous 1de50a2a94 Kernel: Improve ATA device initialization
This does better detection of empty ports and fixes floating bus
read-value from 0x00 to 0xFF.

Bananymous 627ca432cc Kernel: Make PS/2 controller not hang if device keeps sending resend 2024-11-19 00:18:48 +02:00
Bananymous 71563034a7 Kernel: Remove accidentally left debug prints 2024-11-18 03:45:07 +02:00
Bananymous aaff5a65e1 Kernel/init: /dev/tty is now custom symlink to controlling terminal
kernel now passes the name of default console to init process so init
knows which file to open as stdio. before /dev/tty was referencing the
system wide current terminal which was inherited from cmdline. This
doesn't work anymore as we have pseudo terminals implemented that can
chage the current terminal during runtime :D

Bananymous 458a362f98 Kernel: Allow kernel to pass arguments to init process 2024-11-17 22:38:02 +02:00
Bananymous f206e72447 Kernel: Don't require msync addresses to be page aligned
Inodes implementing msync can require page aligned addresses, but are
also allowed to not :) This reduces sizes of framebuffer msyncs!
