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.

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.

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.

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.

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 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.

Bananymous 1337758660 Kernel: Make USB HID interfaces configure all endpoints 2024-07-16 00:23:26 +03:00
Bananymous 339e8a7910 Kernel: Fix USB keyboard state updating with variable reports 2024-07-16 00:03:00 +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
 2024-07-15 11:48:48 +03:00
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 86e9d92ecb Kernel: Take ownership of xHCI controller from bios 2024-07-14 03:31:35 +03:00
Bananymous baa4e6475a Kernel: Implement basic USB Mouse 
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
 2024-07-14 02:04:48 +03:00
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 f120da3aca Kernel: USB device now sets the current configuration 2024-07-12 11:26:06 +03:00

Bananymous e905634343 Kernel: Fix bugs and cleanup USB and xHCI code and API 2024-07-11 14:10:55 +03:00
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 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 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.
