Bananymous da0b4cd40e Kernel: Allow MAP_FIXED in mmap 2024-08-27 22:45:49 +03:00
Bananymous 2c520391eb Kernel/LibC: Add support for init_array and fini_array 2024-08-27 00:47:03 +03:00
Bananymous 7c4b9218f2 Kernel: VirtualTTY now resets ansi state before printing anything 2024-08-25 17:56:06 +03:00
Bananymous 72f8138ca1 Kernel: Disable scheduler load balancing until I get it fixed 
Scheduler keeps crashing all the time when running on multiple cores.
This patch disabled the load balancer, which seems to get rid of most
scheduler crashes.

Bananymous 991ae4383a Kernel/LibC: Implement fchmod 2024-08-25 15:07:42 +03:00
Bananymous 2ce7205c80 Kernel: Add command line option to disable debug printing 
The whole system can crash when debug output and tty output are done at
the same time. This patch is just a hack to prevent the crash :D
 2024-08-25 15:02:15 +03:00
Bananymous fb35f06cf5 Kernel: Add better support for bootloaders loading the kernel 
Before I assumed that bootloaders loaded the kernel at physical address
0, but this patch kinda allows loading to different addresses. This
still doesn't fully work as kernel bootstrap paging relies on kernel
being loaded at 0
 2024-08-22 14:48:21 +03:00
Bananymous abc788c756 Kernel: Improve output message when dumping all syscalls 2024-08-22 14:48:21 +03:00
Bananymous 63b616dc2e Kernel: Hack non-blocking support for sockets 
This is not thread safe and can still block if two programs refering to
the same socket try to read data at the same time
 2024-08-22 14:48:14 +03:00
Bananymous cba12efeb1 Kernel: Ignore optional_actions in SYS_TCSETATTR 
Currently all terminals are syncronous, so the actions don't do anything
 2024-08-22 14:47:54 +03:00
Bananymous 37cd4ed504 Kernel: Add support for CSI @, b, d to VirtualTerminal 2024-08-22 14:04:45 +03:00
Bananymous 869bba4dad Kernel: Add check for panic in timer interrupt handler 
Previously processors would not get notified about kernel panic if they
were idling
 2024-08-22 14:03:03 +03:00
Bananymous 23194d1f53 Kernel: Implement basic random device to /dev/random 2024-08-22 14:02:26 +03:00
Bananymous 969563c06a Kernel: Don't load AP init code to 0xF000, but relocate it later 
This cleans up the kernel executable as bootloaders don't have to
load AP init code straight to 0xF000, but it will be moved there once
kernel is doing the AP initialization.

Bananymous c7b134ba4b Kernel: Fix NVMe controller namespace numbering 
namespace numbers were incrementing globally instead of per controller.
This led to two single namespace controllers creating nvme0n1 and
nvme1n2
 2024-08-18 20:51:10 +03:00
Bananymous ff62c262fe Kernel: Fix PS/2 scancode set 2 keycodes for the bottom row keys 2024-08-18 20:51:10 +03:00
Bananymous 42e2c15e0c Kernel: Add ps2=<scancode set> command line argument

Bananymous b1fe24bb57 Kernel: Hack AML integers to work better 
Something is trying to store into a constant integers. Just by copying
not returning any integers as constants fixes it xD

Bananymous 3f5ee6f414 Kernel: Rewrite the AML conversion API 
This doesn't currently make the interpreter any better, but it will make
further implementation easier to be spec (or hardware...) compliant
 2024-08-15 02:25:45 +03:00

Bananymous f71a29b6c4 Kernel: Implement AliasOp for AML interpreter 2024-08-13 22:42:37 +03:00
Bananymous ec4cfdee23 Kernel: Fix and cleanup a lot of AML code 
Node now have APIs to convert them to buffer, integer and string. This
allows possibility to handle methods that need explicitly use one of the
overloads instead of integer.

This patch also adds handling of DebugOp. This is used quite heavily in
uACPIs test suite.

Bananymous a5a097fa4a Kernel/LibC: Add initial pseudo terminal support 
This patch implements posix_openpt() and ptsname()

grantpt() and unlockpt() are left in LibC as stubs, as posix_openpt
currently does all of the needed work.

Bananymous ad645f31d0 Kernel/LibC: Add setsid() 2024-08-11 00:58:12 +03:00
Bananymous bac3219a01 Kernel: Fix `Pipe::can_read_impl()` 
The logic was inversed, which made all select calls report incorrectly
for pipes. This made terminal emulator just freeze.

Pipes have now a fixed size buffer and pipe clone and close is working
again.
 2024-08-09 16:50:19 +03:00
Bananymous 44f0ec601f Kernel: Expose /proc/meminfo and fix /proc/<pid>/meminfo 
Thread was unconditionally calling <stack>->size() without validating
that the stack actually exists
 2024-08-09 15:58:56 +03:00
Bananymous 2a659a9d03 BuildSystem: Fix enable sse definition 
__enable_sse was never actually defined for any targets. This also adds
__arch definition for libc (so `utsname` works).
 2024-08-09 15:52:42 +03:00
Bananymous 7e7c3a1bb3 Kernel: VirtualTTY now handles dark colors 
I have seemingly forgot to add these before
 2024-08-09 15:52:42 +03:00
Bananymous 7afdfb150f LibC: Rewrite sigprocmask in terms of pthread_sigmask 
Also don't fail SYS_SIGPROCMASK if how is invalid and set is NULL.
 2024-08-07 17:01:35 +03:00
Bananymous 0a7c316ffb Kernel: Fix race condition when blocking threads 
If thread was blocked, but had not reached block queue, you might
already get an unblock request which would fail on an assertion.

If blocked thread was load balanced to another processor and unblocked
simultaneously, there was a race condition.
 2024-08-05 20:14:13 +03:00
Bananymous e72424e01a Kernel: Implement ANSI CSI M and fix ANSI CSI L 
There are not maybe not correct, but work much better than the old ones
 2024-08-05 15:53:01 +03:00
Bananymous a578527012 Kernel/LibC: Implement ioctl(TIOCGWINSZ) 
This allows ncurses to get the window size!
 2024-08-01 22:56:26 +03:00
Bananymous af78a2d080 Kernel: Implement ANSI CSI L for TTY 
vim seems to be using this, so I decided its needed

Bananymous 840000d02b Kernel: Make sure null signal is not send with kill() 2024-08-01 21:41:54 +03:00
Bananymous 9ea4c777ad Kernel: TTY now handles ESC key presses 
This allows exiting vim :D
 2024-08-01 21:41:11 +03:00
Bananymous a33b63d066 Kernel/LibC: Implement alarm() and setitimer() 
This makes vim able to start!
 2024-08-01 21:09:56 +03:00
Bananymous da3b30cd94 Kernel: Add macro to dump all syscalls and their return values 2024-08-01 18:21:49 +03:00
Bananymous 4599e1dec5 Kernel: Make schedler not crash when unblocking active thread 
This was happening when sending signals to processes that were currently
running.
 2024-08-01 18:21:49 +03:00
Bananymous 6de350ce9d Kernel/LibC: Cleanup, fix and implement a lot of signal code 
This patch implements sigsets and some of their usages
 2024-08-01 17:01:18 +03:00
Bananymous 838d31fa41 Kernel: Implement more POSIX compliant open() and openat() syscalls 2024-08-01 15:35:02 +03:00

Bananymous 681d8327f5 LibC/Kernel: Cleanup termios code 
This is still not correct, but much better than it used to be
 2024-07-30 11:10:43 +03:00
Bananymous 9bc02c81f8 Kernel: Map DMA and PCI MMIO as uncached 2024-07-30 11:10:08 +03:00
Bananymous bb1738db8c Kernel: Make thread unblocking O(1) 
This is still bit broken. VirtualBox seems to freeze sometimes, but I
could not recreate this on qemu (with and without kvm) or real hardware.
 2024-07-24 00:31:01 +03:00
Bananymous 9548c592a3 Kernel: Always print basic info about xHCI controller 
Its nice to see that the controller is getting initalized
 2024-07-23 09:09:08 +03:00
Bananymous cda0276d39 Kernel: Force PCI irq line usage when not using APIC 
afaik PIC does not support MSI
 2024-07-23 09:08:00 +03:00
Bananymous 539afb329a Kernel: All processors use LAPIC timer when running with APIC 
This makes scheduler preemption much cleaner as bsb does not have to
send smp messages to notify other processes about timer interrupt.

Also PIT percision is now "full" 0.8 us instead of 1 ms that I was using
before.
 2024-07-23 02:28:52 +03:00
Bananymous 3e0150f847 Kernel: Pressing F1 now toggles rendering of CPU loads to the terminal 
This can be nice for seeing the performance and problems on the load
balancing algorithm.
 2024-07-22 00:43:13 +03:00
Bananymous f8261c60c0 Kernel: Rewrite the whole scheduler and re-architecture SMP handling 
Change Semaphore -> ThreadBlocker
  This was not a semaphore, I just named it one because I didn't know
  what semaphore was. I have meant to change this sooner, but it was in
  no way urgent :D

Implement SMP events. Processors can now be sent SMP events through
IPIs. SMP events can be sent either to a single processor or broadcasted
to every processor.

PageTable::{map_page,map_range,unmap_page,unmap_range}() now send SMP
event to invalidate TLB caches for the changed pages.

Scheduler no longer uses a global run queue. Each processor has its own
scheduler that keeps track of the load on the processor. Once every
second schedulers do load balancing. Schedulers have no access to other
processors' schedulers, they just see approximate loads. If scheduler
decides that it has too much load, it will send a thread to another
processor through a SMP event.

Schedulers are currently run using the timer interrupt on BSB. This
should be not the case, and each processor should use its LAPIC timer
for interrupts. There is no reason to broadcast SMP event to all
processors when BSB gets timer interrupt.

Old scheduler only achieved 20% idle load on qemu. That was probably a
very inefficient implementation. This new scheduler seems to average
around 1% idle load. This is much closer to what I would expect. On my
own laptop idle load seems to be only around 0.5% on each processor.
 2024-07-22 00:33:50 +03:00
Bananymous 9f90eeab05 Kernel: Fix stack pointer OOB check 
i686 does not push the stack pointer on interrupt when no CPL change
happens.
 2024-07-22 00:27:08 +03:00
Bananymous 1ee37cb671 Kernel: Make sure stack is aligned on interrupts for i686 target 
I just realized that only x86_64 aligns stack pointer when interrupt is
triggered.
 2024-07-22 00:10:42 +03:00
Bananymous 8fe798de6d Kernel: Make PIT counter atomic with spinlock 2024-07-21 18:56:41 +03:00
Bananymous 86b6714777 Kernel: Add command line option to boot without smp 2024-07-21 17:40:57 +03:00
Bananymous 77b5e6d44a Kernel: Make ATABus use BAN::Atomic<> instead of gcc builtin atomics 2024-07-21 17:39:26 +03:00
Bananymous ffe73165f9 Kernel: Fix PCI typo serail -> serial 2024-07-21 17:36:29 +03:00
Bananymous 96c7e9e29d Kernel: Cleanup VirtualRange code 
Virtual range does not need to look into the page table for mapped
physcial pages. It can (and should) just keep track of them itself.
 2024-07-21 17:35:07 +03:00
Bananymous 02051ed60f Kernel: Move keyboard kernel panic to the general input device 
This will allow command to work without requiring it per keyboard driver
 2024-07-21 17:33:38 +03:00
Bananymous f49689caac Kernel: Implement API for sending IPIs for only one processor 
Also move the spin wait to check for pending IPI sends to the start of
ipi sending function. There is no need to wait for IPI send succeeding
right after it. It is enough to make sure there are not multiple IPIs
being sent at the same time.
 2024-07-21 17:30:59 +03:00
Bananymous 974b9b992d Kernel: Fix process exiting infinite loop 
If process was exiting and had a process waiting for it and that waiting
process got interrupted, the exiting process could never exit.
 2024-07-18 21:40:44 +03:00
Bananymous 4b917390ac Kernel: Fix sse state saving 
This was broken when I added SMP support. This patch makes sse kind of
dumb as it is saved and restored on every interrupt, but now it at least
works properly... I'll have to look into how sse can get optimized
nicely with SMP. Simple way would be pinning each thread to a specific
processor and doing pretty much what I had before, but sse thread saved
in processor rather than static global.
 2024-07-16 23:15:11 +03:00
Bananymous 7a0fb9a57f Kernel: Fix TTY scroll clearing first and/or last characters from line 2024-07-16 22:49:49 +03:00
Bananymous 58fcd2b2fe Kernel: Fix multi-interface USB device initialization 2024-07-16 22:29:18 +03:00
Bananymous e30952efee Kernel: Implement key repeating for USB keyboard 
USB keyboards don't send repeating keys automatically, so it has to be
emulated in software.
 2024-07-16 11:54:57 +03:00
Bananymous 1337758660 Kernel: Make USB HID interfaces configure all endpoints 2024-07-16 00:23:26 +03:00

Bananymous a60b460701 Kernel: Update USB HID code to support multiple top-level collections 
This allows me to use my laptops own keyboard!
 2024-07-16 00:01:53 +03:00
Bananymous a5cb4057f9 Kernel: Implement unified input files for device hot-plugging support 
/dev/keyboard and /dev/mouse can be read for events from any attached
keyboard or mouse respectively. This makes device hot-plugging support
pretty much automatic for TTY, GUI, and whatever takes input.
 2024-07-15 22:11:15 +03:00
Bananymous 9d7f97ccd5 Kernel: Implement DevFileSystem::remove_device 
This function cleanly removes the devices from the whole filesystem.

USB devices are now removed from the filesystem as soon as they are
destroyed.
 2024-07-15 22:10:42 +03:00
Bananymous 0578d41500 Kernel: Implement WriteCombining memory 
This makes framebuffer much faster on real hardware
 2024-07-15 22:09:09 +03:00
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.
 2024-07-15 15:51:07 +03:00
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 
Fix USB Keyboard scan code table for bottom row of keyboard

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

This has the same problem I described in previous commit for keyboard
 2024-07-14 02:11:32 +03:00
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...
 2024-07-14 02:09:18 +03:00
Bananymous 1efc6a1385 Kernel: Implement simple USB HID driver 
This should be easily expandable to add HID devices

Bananymous 749be67df3 Kernel: Fix cxxabi for function static variable guards 2024-07-14 01:53:50 +03:00
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 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 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 d7b8458a56 Kernel: Fix TCP sending 
TCP send was effectively always waiting for connection to close and then
return a value of 0.

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

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.

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.
