Bananymous 42237a3bc8 Kernel: Implement fast scrolling for TTY 2024-06-28 23:15:03 +03:00
Bananymous 48a76426e7 BAN: Add more APIs for Atomic and make compare_exchage take a reference 2024-06-28 21:47:47 +03:00
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 cb07142832 Kernel: ACPI allow more calling or \_S5 
Spec says that \_Sx must have 4 fields, but virtual box seems to only
have the two defined once. This patch allows shutodown on virtual box

Bananymous 60a05412c9 Kernel: ACPI implement SizeOf 2024-06-25 23:24:51 +03:00
Bananymous 0179f5ea09 Kernel: ACPI add \_OS string 2024-06-25 23:24:19 +03:00
Bananymous f671ed7e3f Kernel: ACPI implement integer stores to registers as copies 
Before storing const integer and then modifying the register it would
error.

Bananymous 2fccff5a35 Kernel: Implement ACPI IndexOp into Strings 2024-06-25 23:23:00 +03:00
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 25099b4c98 Kernel: Don't validate O_SEARCH for non-directories 2024-06-25 19:27:55 +03:00
Bananymous d7b8458a56 Kernel: Fix TCP sending 
TCP send was effectively always waiting for connection to close and then
return a value of 0.

Bananymous 67dfe0bcf3 BAN: Allow String::formatted to fail 2024-06-25 11:04:03 +03:00
Bananymous 9e1b5cbaab BuildSystem: Cleanup CMake code to allow libc only installation 
There was no way to just install libc which is required for stdlibc++
 2024-06-21 01:45:14 +03:00
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 ad6d95ba52 BuildSystem: Rework the whole cmake build system 
Now files are installed using the install() command instead of manually
copying files to their destinations. This allows automatic recompilation
of headers that did not work previously
 2024-06-19 09:40:03 +03:00
Bananymous 318ce5dec8 All: Fix a lot of compiler warnings from header files 
While reworking build system, header files started to report warnings.

Bananymous c69919738b BuildSystem: Move all userpace libraries under the userspace directory 
As the number of libraries is increasing, root directory starts to
expand. This adds better organization for libraries

Bananymous f1e366d36f Kernel: Free keyboard mutex while waiting for data to read 
This was making select hang if one thread was trying to read from
keyboard.
 2024-06-17 23:04:37 +03:00
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 cad55a4da5 Kernel/LibC: Implement getsockname for ipv4 sockets 2024-06-17 20:54:45 +03:00
Bananymous 511fc870a1 BAN: Mark RefPtr and WeakPtr operator bool() as explicit 2024-06-17 20:19:36 +03:00
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 6b1d5d28be Kernel: VFS root now has to be block device instead of partition 2024-06-14 00:19:12 +03:00
Bananymous 766439db6d Kernel: Start work on adding support for new filesystems 
Old code tried to create ext2 filesystem from all devices.

Bananymous d4903caafa Kernel: Combine consecutive mouse move and scroll events 
This makes mouse work much smoother when running without kvm.

Bananymous ffacff67cf LibFont: Move PSF code to separate file 2024-06-10 16:10:05 +03:00
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 765ccfa18c Kernel: Deliver SIGCHLD on process exit and ignore it properly 2024-06-03 17:58:24 +03:00

Bananymous aec5a09caf Kernel/LibC: Implement SYS_ISATTY and isatty() 2024-06-03 03:36:25 +03:00
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 8bfacb0091 Kernel: Implement deletion of SMO objects 2024-05-31 13:04:23 +03:00
Bananymous 0501f3bd99 Kernel: Move font code to its own library LibFont 2024-05-31 10:47:05 +03:00
Bananymous 84b3289a2a Kernel: Move Scheduler::yield() lock check after interrupts disabled 
I have no idea why this solves a bug where current processor has
scheduler lock at the beginning of yield.

Bananymous b760892de2 Kernel: Make pselect use nanosecods instead of milliseconds 2024-05-31 02:56:17 +03:00
Bananymous 6840a8983c Kernel: Make sure MSB is not set on SMO keys 2024-05-29 20:01:12 +03:00
Bananymous a1b3490764 Kernel: Improve random number generation for unsigned types 2024-05-29 20:00:47 +03:00
Bananymous 076f1efecb Kernel: Fix 32 bit fast page locking 
I forgot to change this when changing the lock type. 32 bit boots again
fine :D
 2024-05-29 19:44:39 +03:00
Bananymous 53e572f072 Kernel: Fix s_fast_page_lock type on 32 bit target 2024-05-29 18:04:23 +03:00
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 99270e96a9 Kernel: Lock debug lock while printing fault details 
This allows multiprocessor to dump clean output on concurrent faults

Bananymous 4bf7a08c80 Kernel: Allow SYS_PSELECT to work with timeout of zero 2024-05-29 15:32:18 +03:00
Bananymous 3823de6552 Kernel: Add templated get function for Random 2024-05-29 15:32:00 +03:00
Bananymous 8bc6c2eb20 Kernel: Move KeyEvent/MouseEvent from kernel to LibInput 2024-05-28 23:30:08 +03:00
Bananymous 87d52e5ebe Kernel: Fix timer early wake message 
When printing early return message, current time was read twice. This
could lead to early return check failing, but when printing and reading
the time again subtraction overflow would happen.

Bananymous 598a09c13d Kernel: Allow select to work on any type of inode 2024-05-28 16:03:54 +03:00
Bananymous 18e2559b1e Kernel/LibC: Add SYS_TRUNCATE 2024-05-28 01:08:04 +03:00
Bananymous a1ab44d39f Kernel: Optimize disk reads to read multiple sectors at once 
Old StorageDevice::read_sectors() read each sector separately if the
underlying disk had a disk cache. This patch allows multiple sectors to
be read even if the disk cache exists and contains some of the sectors.

Only sectors that could not be found from the disk cache are actually
read from the disk. This optimization is not done for writing, which
still will write each sector separately, if disk cache has no memory to
store new sectors. It would feel kind of unnecessary optimization as you
have greater problems if disk cache cannot allocate a single page.

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.
