Bananymous e19414a64e BuildSystem: Fix GCC compilation with new host GCC 
Newer GCCs fail to compile GCC 15.2.0 because of how u8"" literals are
handled. This can be bypassed by compiling with -fno-char8_t

Bananymous 16a442f473 Kernel: Fix Thread::will_exit_because_of_signal

ignore the signal leading to infinite busy loops :)

Bananymous 585e021c7f Kernel: Don't panic when stack trace leads to GPF 
if there is was a uncanonical address in stack trace we ended up in an
infinite recursive loop trying to print stack trace

These can just open files in /tmp/shm. no need for anything fancier

Bananymous 2a6792b44a LibC: Make mlock, munlock and madvice no-ops 
These don't have to do anything as I don't swap processes to disk

previously it was only on the sockets
 2026-05-25 02:14:04 +03:00
Bananymous c72f2f9b31 LibC: Fix posix_spawn 
signal was checking for NULL instead of SIG_ERR

there is no need to do post fork waiting in posix_spawn, we just have to
exit with 127 on error

Bananymous 62e2f4896a LibC: reorder LOCK_SH and LOCK_EX 
Some software im porting has static asserts for these :)

Bananymous ee5c225954 LibC: Add __fseterr 
This is used by some ports to not require internal FILE structure

Bananymous 8fccb74542 Kernel: Add indirect block cache to ext2 inode 
This reduces indirect block lookup by a lot :)

Bananymous bc8ecbd6fa Kernel: Add directory entry cache for ext2 inodes 2026-05-25 02:14:04 +03:00
Bananymous 60484b286f Kernel: Fix bugs in sys_pselect 
I was not validating nfds passed from userspace. Also invalid fds are
supposed to return EBADF instead of ignoring those entries
 2026-05-25 02:14:04 +03:00
Bananymous 12158d9208 Kernel: Add OpenFileDescriptorSet::get_max_open_fd 2026-05-21 14:59:35 +03:00
Bananymous 5c94c30e1b Kernel: Use spinlocks instead of mutexes for RWLock 
All the operations are super fast, just checking or changing few
integers, there is no need for a yielding mutex :^)
 2026-05-21 02:17:34 +03:00
Bananymous 81d8ab3d79 Kernel: Remove completely unnecessary lock on file lookup 
Mount point lookup already does locking internally, there is no need for
a lock for the whole duration of the lookup :D

Bananymous ed3924722e Kernel: Remove kernel CPU load printing 
We still keep track of processor loads but the hacky printing is no
longer done in kernel space :)

DcraftBgandBananymous 77796dd317 driver-install: implemented a simple installer 2026-05-20 17:52:19 +03:00
DcraftBgandBananymous f1a72cc9da Kernel: Implemented banos - a WIP C driver API 
Banos is a stable WIP C driver API that is supposed to provide a simple
interface to interact with the kernel and load the modules dynamically.
It is WIP and atm this just implements module loading with a custom
banos_install syscall. Banos will not try to substitute parts of the
kernel instead it will just expose kernel functionality via a stable
BINARY API. Meaning binaries (should) remain forward and backward
compatible on a binary level.

Banos modules work similarly to those in linux, you expose symbols via
BANOS_EXPORT which allows you to export a name + addr paired symbol.
It puts it in the .banos-export section. Drivers provide metadata about
themselves in the REQUIRED .banos-driver section. Symbols are resolved
at runtime. The kernel exposes the driver functionality via the same
.banos-export export mechanism.

Banos modules are elf RELOCATABLE files (object files) which have
partial linking (only banos symbols should remain). Modules will
eventually define dependencies, will export symbols and will allow you
to build a complex object hierarchy.

This patch adds the banos_install syscall which takes in the driver
image to install and may only be executed by super users. The API
doesn't validate already loaded modules, as thats something the
userspace MAY choose to keep track of. Multi-instance functionality
shall be implemented via driver specific behaviuor (exposed in the dev
filesystem or some other means).

Modules are supposed to allow you to alter kernel behavior and extend
it, allowing you to create filesystems, drivers, networking
modifications, schedulers, probers, and more (hopefully) whilst
remaining binary compatible with any version of the kernel (again,
hopefully).

Bananymous 14aa28b043 Kernel: Handle TTY ioctls on all inodes not implementing it 
This reduces debug spam while compiling software

Bananymous 6045726e41 Kernel: Optimize PageTable::unmap_range on x86_64 2026-05-20 16:16:44 +03:00
Bananymous 45e55d8907 LibC: Don't compare equal elements in qsort 
This seemed to break supertuxkart which returned `less` in this case

Bananymous a19e6938eb Kernel: Remove TTY keyboard thread 
This was really hacky as it had no idea when the keyboard had events
and the blocking was just one millisecond sleeps :D

Now keyboard device checks if current tty is receiving input and if so
it forwards the events to the TTY.

Bananymous 32206069bc Kernel: Use per cpu fast page for {Memory,File}BackedRegion 2026-05-20 02:51:48 +03:00

Bananymous a3ca49ff1f Kernel: Don't sync ext2 inode on read 
This is the most common operation and we don't even update any fields
during read (although we should update atime). The disk read+write is a
bit too heavy with the current cache system
 2026-05-20 02:14:40 +03:00
Bananymous 94f92d982c Kernel: Optimize PageTable address space reservation 
I only did this for the 64 bit target.
