Bananymous 2957206718 LibC: Fix and cleanup stdio mode string parsing 
The code is now much cleaner andd we are not as strict with the mode
string. Also add support for new 'e' and 'x' modifiers

Bananymous 652e170da9 LibGUI: Ignore failing smo maps in resize event 
This can be caused by sending two back-to-back resize requests. When
handling the first, the server may have already replaced the smo key
with a new one.

Bananymous 63b2284324 Kernel/LibC: support RDTSCP based clock_gettime 
RDTSCP seems to be faster than LSL and it removes the need for getting
the current cpu twice to make sure TSC is read on the correct CPU
 2026-07-03 06:32:04 +03:00
Bananymous 917321eb5f LibC: Wait for thread before returning from pthread_create 
We now make sure the thread starts up and sets its id. There was a race
condition where a process could create a thread and immediately try to
join it. If the thread had not initialized itself the join would fail
with EINVAL as we passed -1 as its id.

Bananymous 0a8b03d349 LibAudio: Make AudioLoaders return float instead of double 
AudioBuffers already use floats internally so there is no need for
loaders to produces doubles

Bananymous 7219eac65f Kernel: Remove unnecessary page table validation 
Processes always have a page table when they are initialized. This was
not true a long time ago when kernel threads could also be processes
 2026-07-02 20:02:24 +03:00
Bananymous 0dc74beb0f Kernel/LibC: Allocate thread stacks in userspace 
This adds support for pthread function for stack manipulation.

Also keep track of main threads stack in the uthread
 2026-07-02 20:02:24 +03:00

Bananymous 6d1696b77e Kernel: Don't allocate userspace stacks in Thread 
Thread only cares about stack's vaddr and size. Stacks are now allocated
before creating the threads.
 2026-07-02 20:02:24 +03:00
Bananymous b19b7f064a LibC: Make pthread_t pointer to uthread instead of a thread id 
This will allow getting info about other threads in userspace!
 2026-07-02 20:02:24 +03:00
Bananymous f449ca8161 Kenrel: Separate pthread API from kernel API 
It didn't really make sense for the syscalls to be named as the pthread
equivalents. Now the kernel just uses thread ids
 2026-07-02 20:02:24 +03:00
Bananymous 5540bc4147 Kernel: Fix USB SCSI device naming 2026-07-02 20:02:24 +03:00
Bananymous d8f136a76f Kernel: Remove the weird StorageController base class 
This wasn't really used for anything and broke nvme controller as it was
now doubly ref counted :P

condition
 2026-07-02 15:22:52 +03:00
Bananymous d241975ce1 Kernel: Remove SYS_SLEEP and cleanup SYS_NANOSLEEP 
`sleep` is now implemented in terms of `nanosleep`. `nanosleep` is now
more precise and handles overflow when calculating wakeup time. I don't
think anything was depending on this, but I could see a program sleeping
for max time to block until signal.
 2026-07-02 15:22:52 +03:00
Bananymous 20663b533b Kernel: Rework sleeping API 
instead of sleep_{ns,ms} we now have sleep_{for,until}_{ns,ms}. This
makes code cleaner that just wants to sleep until some timestamp

Bananymous c0bd07174d Kernel: Reduce the number of E1000 register reads while receiving 
There is no need to read and write the receive tail pointer for every
packet. This change bumped my TCP speed from ~11MB/s to ~40MB/s which is
my network speed limit
 2026-06-30 20:14:38 +03:00

Bananymous 6339044e4c Kernel: Fix RTL8169 driver 
This now works properly on real hardware. Main issue was a race
condition with now ISR was handled in the interrupt handler. We now loop
until we read back ISR as zero
