Bananymous 42c3fa24f0 Kernel: Add support for HID Report ID and parsing all collections
Only the first top-level collection is used for the device, but that
seems to generally be what keyboard and mouse use for input.

Bananymous 60b396fee5 Kernel: Add mouse move and scroll event merging back
This makes mouse work much faster when reading can't keep up with the
amount of events.

Bananymous 4cd9252ff6 Kernel: Fix USB code

Support multiple interfaces on a single USB device

Add usb mouse to default qemu settings

Bananymous 75875d3a8f Kernel: Set interval and average trb length on configure endpoint
Real controllers seem to require this while spec 4.8.2.4 says that they
should be left as zero.

Bananymous baa4e6475a Kernel: Implement basic USB Mouse
This has the same problem I described in previous commit for keyboard

Bananymous ac5c77ee2c Kernel: Implement USB Keyboard
This is kinda hacky, as I had disable the PS/2 initialization so that
usb keyboard gets /dev/keyboard0. I should add device hot plugging
support for TTY and GUI...

Bananymous 1efc6a1385 Kernel: Implement simple USB HID driver
This should be easily expandable to add HID devices

Bananymous a97a574718 Kernel: Rewrite the whole input system
PS/2 code is now kind of messed up, but it works. Keyboards and mice are
now an abstract class that is automatically exposed to userspace. This
will make adding USB input much nicer.

Bananymous 14dce1abac Kernel: Start work on USB stack
Current code can enumerate all xHCI devices and detect their type based
on the class code on device or interface descriptors.

Bananymous 31568fc5a1 Kernel: Rewrite Sockets to not be TmpInodes
TmpInodes just caused issues because TmpFS kept them alive. There was
really no reason for sockets to even be stored inside a TmpFS...

Bananymous f671ed7e3f Kernel: ACPI implement integer stores to registers as copies
Before storing const integer and then modifying the register it would
error.

Bananymous af4b138094 Kernel/LibC: Implement realpath
realpath is implemented as a syscall. This is not really required but it
was the easiest way to get it working as there is already path
canonicalization at kernel level.

Bananymous 4f0457a268 Kernel: Rewrite a lot of TCP code and implement TCP server sockets
TCP stack is now implemented much closer to spec
2024-06-20 13:26:50 +03:00
Bananymous bce16cdd6e Kernel: Fix how socket closing works
Sockets are now closed only when they are not referenced any more. This
allows child process to close socket and still keep it open for the
parent.

Bananymous 318ce5dec8 All: Fix a lot of compiler warnings from header files
While reworking build system, header files started to report warnings.

Bananymous be7ed8e74a Kernel/LibC: Implement {get,set}sockopt()
These are pretty much dummy functions in the kernel side. Only case that
is handled is SOL_SOCKET with SO_ERROR. This is hard coded to return no
error. Network stack is currently synchronous, so all errors are already
reported through synchronous network functions.

Bananymous ea7fc7f6c4 Kernel: Implement read-only FAT12/16/32 driver with long name support
You can now mount FAT filesystems! This code might not work perfectly
but my quick testing seemed to work on all (FAT12/16/32) variants.

Bananymous 766439db6d Kernel: Start work on adding support for new filesystems
Old code tried to create ext2 filesystem from all devices.

Bananymous 530c259e71 Kernel: Close unix domain socket when it gets destoyed
Inode closing is something that needs a complete rework. Currently all
sockets are closed when close() is called, which leads to connection
closing if you fork()/exec() with socket being marked as CLOEXEC.

Inodes should probably only be closed once they are not referenced
anywhere.

Bananymous 446220494e Kernel: Unix domain sockets close can now be detected
When a unix domain socket is closed and it has a connection to another
socket, it will make the other socket readable and recv will return 0.

This allows detection of socket closing

Bananymous d4d530e6c8 Kernel: Implement basic shared memory objects
These can allocate memory that can be shared between processes using
a global key. There is currenly no safety checks meaning anyone can
map any shared memory object just by trying to map every possible key.

Bananymous 8b1514e575 Kernel: Make all storage devices readable and writable
I only had a {read,write}_impl defined for ATABaseDevice. This patch
moves that implmentation to general storage device.

Bananymous 2d3810874d Kernel: Fix thread signal handling
Threads will now only handle signals once they are not holding any
mutexes. This removes some dead locks.
2024-05-26 20:08:35 +03:00
Bananymous 2a4d986da5 Kernel: Add preliminary support for PCIe
Only segment 0 is supported, but devices can now be accessed through
mmio.

Adding more segments would require adding argument to every PCI API so
it is left for later.

Bananymous df260fe0e8 Kernel: Process::validate_pointer_access now maps the whole range
This fixes a bug where userspace provided address is not fully mapped
and the kernel tries to read/write it while using PageTable fast page.

In the future userspace input should be copied on syscall entry, so
userspace could not modify the input during syscall. Currently there
is change that userspace input passes kernel syscall validation and
after that userspace could modify the input before the value is
actually used.

Bananymous 2be4fe8404 Kernel: Make PageTable::s_fast_page_lock non-recursive
This lock is only used in wrapper of PageTable. There is no possiblity
of taking the lock outside of these wrappers.

Bananymous 0af74fccda Kernel/LibC: Rework dirent structure
dirent now contains statically sized d_name. This allows using
sizeof on the name and dirent properly, which some programs seem
to be using.
