Bananymous 4d3751028b LibInput: Honor chroot and credentials when loading keymap 2026-04-06 19:29:34 +03:00
Bananymous e4c6539964 Kernel: Be more clever with physical memory 
Initially allocate all physical memory except kernel memory and boot
modules. Before we just skipped all memory before kernel boot modules.
Also release memory used by boot modules after the kernel is up and
running. Once the boot modules are loaded, there is no need to keep them
in memory.

Bananymous 34b59f062b LibC: Implement blocking pthread_rwlock 
pthread_rwlock now uses a mutex and condition variable internally so it
doesn't need to yield while waiting!
 2026-04-06 19:29:34 +03:00
Bananymous ec4aa8d0b6 LibC: Fix shared pthread_barrier init 
Initialize internal lock and cond as shared when the barrier is shared
 2026-04-05 12:06:18 +03:00
Bananymous 1eebe85071 LibC: Fix pthread_cond_timedwait 
If timeout occurred, I was not removing the entry from block list

Bananymous db0507e670 LibC: Mark pthread_exit noreturn 2026-04-05 11:30:45 +03:00
Bananymous 1e3ca7dc18 Kernel: Fix signal related syscalls 
There were missing locks, out of order sigprocmask, incorrect signal
masking...
 2026-04-05 02:31:30 +03:00
Bananymous 8ca3c5d778 Kernel: Clean up signal handling 
We now appreciate sa_mask and SA_NODEFER and change the signal mask for
the duration of signal handler. This is done by making a sigprocmask
syscall at the end of the signal handler. Back-to-back signals will
still grow stack as original registers are popped AFTER the block mask
is updated. I guess this is why linux has sigreturn(?).

Bananymous df257755f7 Kernel: If userspace sets fs or gs, dont overwrite it 
Current cpu index is stored at either segment. If userspace sets that
segment, kernel will not overwrite it on every reschedule. This is fine
as long as user program does not use anything that relies on it :)
 2026-04-04 23:48:43 +03:00
Bananymous d7e292a9f8 Kernel: Drop 32 bit userspace stack to 4 MiB 
32 bit userspace only has 256 MiB reserved for stacks, so with 32 MiB
stacks it only allowed total of 7 threads. Now we can have up to 62
threads
 2026-04-04 23:48:43 +03:00
Bananymous 9fce114e8e Kernel: Don't clone entire kernel stack on fork 
We only need to copy area between [ret_sp, stack_end]. This range is
always very small compared to the whole stack (64 KiB).
 2026-04-04 23:48:43 +03:00
Bananymous 9d83424346 Kernel: Remove unnecessary stack pointer loading 
Any time I started a thread I was loading the stack pointer which is
already correctly passed :D
 2026-04-04 23:48:43 +03:00
Bananymous a29681a524 Kernel: Fix signal generation 
We need to have interrupts enabled when signal kills the process as
process does mutex locking. Also signals are now only checked when
returning to userspace in the same place where userspace segments are
loaded.
 2026-04-04 23:48:43 +03:00
Bananymous 47d85eb281 Kernel: Pass the actual vaddr range to reserve pages 2026-04-04 23:48:43 +03:00
Bananymous 85f676c30a DynamicLoader: Calulate max loaded file count based on dtv size 
dtv should be dynamic but i dont care right now :)
 2026-04-04 23:48:43 +03:00
Bananymous 8c5fa1c0b8 DynamicLoader: Fix R_386_PC32 relocation

Bananymous c7690053ae LibC: Don't crash on 32 bit pthread_create 2026-04-04 23:48:43 +03:00
Bananymous 3f55be638d Kernel: Allow reserve_free_page{,s} to fail 
Apparently I was asserting here before :D
 2026-04-04 23:48:43 +03:00
Bananymous 664c824bc0 Kernel: Keep fast page always reserved 
There was a bug where 32 bit target's reserve_free_page was allocating
the fast page address
 2026-04-04 23:48:43 +03:00
Bananymous e239d9ca55 ports/SDL2: Use 48 kHz floats instead of 44.1 kHz PCM16 2026-04-03 16:17:16 +03:00

Bananymous 675c215e6a Kernel: Add CoW support to MemoryBackedRegion 
This speeds up fork by A LOT. Forking WindowServer took ~90 ms before
this and now its ~5 ms.

Bananymous f77aa65dc5 Kernel: Cleanup accessing userspace memory 
Instead of doing page validiation and loading manually we just do simple
memcpy and handle the possible page faults

Bananymous e9c81477d7 BAN/LibC: Implement remainder

Bananymous 5c20d5e291 Kernel: HDAudio hide unusable pins and cleanup path finding 2026-03-24 01:16:47 +02:00
Bananymous f89d690716 Kernel: HDAudio only probe codecs in STATESTS 
This removes unnecessary probing that lead to timeouts. Also cap codec
address at 14 instead of 15. My test laptop was duplicating codec 0 at
address 15 leading to duplicate devices.

Bananymous 09292bb87e BAN: Cleanup math code and add SSE sqrt 
We should prefer SSE instructions when they are easily available. For
other functions x87 is just simpler. It's hard to write faster and close
to as accurate approximations with SSE.

This does not use xmmintrin.h as clangd does not like that file and
starts throwing errors in every file that includes this :)

Bananymous e1c337a483 LibC: Fix compile and link flags 
We were linking with -nostdlib and manually linked against libgcc. This
does not link with crtbegin and crtend which provides __dso_handle

Now we just don't link against libc fixing this issue

Bananymous ff378e4538 Kernel: Cleanup and optimize TCP 
We now only send enough data to fill other ends window, not past that.
Previous logic had a but that allowed sending too much data leading to
retransmissions.

When the target sends zero window and later updates window size,
immediately retransmit non-acknowledged bytes.

Don't validate packets through listeing socket twice. The actual socket
will already verify the checksum so the listening socket does not have
to.
