Bananymous d20752c318 Kernel: Make OpenFileDescritorSet::open take rvalue
This gets rid of some implicit allocations from copy constructors

Bananymous 5f66ef34dd Kernel: map userspace arguments after the entry point
This allows cleaner memory layout for processes that are not loaded to

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 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

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

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 ec4cfdee23 Kernel: Fix and cleanup a lot of AML code
Node now have APIs to convert them to buffer, integer and string. This

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

Bananymous 0a7c316ffb Kernel: Fix race condition when blocking threads
If thread was blocked, but had not reached block queue, you might

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.

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

being sent at the same time.

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.

Bananymous a5cb4057f9 Kernel: Implement unified input files for device hot-plugging support

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.

TCP send was effectively always waiting for connection to close and then
return a value of 0.

Bananymous 9e1b5cbaab BuildSystem: Cleanup CMake code to allow libc only installation
There was no way to just install libc which is required for stdlibc++

Bananymous 4f0457a268 Kernel: Rewrite a lot of TCP code and implement TCP server sockets
TCP stack is now implemented much closer to spec

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

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.

You can now mount FAT filesystems! This code might not work perfectly
