Bananymous 7223e581a2 WindowServer: Fix 32 bit compilation with -Werror

warning about.

Bananymous 2d11ce9669 Kernel: Fix interrupt system 
I had not understood how MSIs work and I was unnecessarily routing them
through IOAPIC. This is not necessary and should not be done :D

Also MSIs were reserving interrupts that IOAPIC was capable of
generating. Now IOAPIC and MSIs use different set of interrupts so
IOAPIC can use more interrupts if needed.

for inverting colors
 2024-09-26 15:07:08 +03:00
Bananymous 1a6804b4b4 Terminal: Make Terminal::handle_csi() return invalidated rectangle 
When I updated Terminal to only do a single invalidation after all of
input text was printed, I forgot to change handle_csi

This allows exiting vim when using this function for key mappings :D
 2024-09-24 18:08:34 +03:00
Bananymous 4e9f39384a LibC: Initialize libc only once 
This was breaking stuff with dynamic loader initializing libc and main
executable reinitializing it later :D
 2024-09-24 17:56:12 +03:00
Bananymous 39802b56c1 Kernel: Allow SYS_EXEC to fail at any point 
This patch builds new executable image to another pml4 structure and
only after everything is validated will current context be replaced.
This allows exec to fail "late" where previously it would panic the
kernel or kill the process. This allows graceful handling of exec
failures in userspace!
 2024-09-24 16:29:38 +03:00
Bananymous ebb87ccdde Kernel: Add asserts for overflow checks with ms -> ns conversions 2024-09-24 16:28:44 +03:00
Bananymous f0e55938c1 Kernel: Allow initial binding of threads to specific processor 2024-09-24 16:27:40 +03:00
Bananymous 348d04f7f5 Kernel: Implement static Process::kill() 
This allows killing processes even when there does not exist a current
thread.

Bananymous 1b0086217c Terminal: Do scrolling in putchar if necessary 
I overlooked that handling *newline* scrolls would be enough. You can
definitely scroll more if printing a lot of text which wraps to the next
line.

Bananymous d395cf38b7 Kernel: Binding to port 0 will always find unused port 2024-09-22 17:30:01 +03:00
Bananymous 57aec2a733 Kernel: Validate pointer's when printing stack trace 
There was an kernel panic if stack trace contained uncanonical
addresses.
 2024-09-22 17:16:01 +03:00
Bananymous ae89237453 Kernel: Disable warning when calling syscall 
This warning is only generated when compiling with UBSAN and I don't see
how the value would even be uninitialzed.
 2024-09-22 17:15:07 +03:00
Bananymous 60d5257678 Kenrel: Add __builtin_unreachable support for UBSAN 2024-09-22 17:14:36 +03:00
Bananymous d59463d11b Kernel: Fix TTY reading one keyevent after disabling input handling 2024-09-22 17:13:10 +03:00
Bananymous 1280528e4e BuildSystem: Use -O2 for all libraries 
I don't know why I had not specified optimization level for libraries.
Only LibImage was using explicit -O3. LibImage doesn't need O3 anymore
as O2 seems to be around the same speed.

Bananymous 23d6205659 Kernel: Move DEBUG_* macros to centralized Debug.h 
This makes toggling debug info much easier
 2024-09-20 11:00:07 +03:00

This caused a lot of crashes on invalid packets :D
 2024-09-20 10:46:59 +03:00
Bananymous b8622f2b4b Kernel: Implement simple RTL8169 driver 
This allows me to use internet when running banan-os on my hardware!

Bananymous 7f0c39fe91 Kernel: Don't crash the kernel if packet is smaller than ethernet hdr 2024-09-19 22:51:55 +03:00
Bananymous a489be0e05 Kernel: Allow parallel LAPIC timer initialization with HPET 
HPET supports reading LAPIC counter without locks, so it can be done in
parallel. This makes booting much faster. Previously initializing every
timer took 100 ms, so 16 CPUs took total of 1.6 seconds. This allows
doing it all in 100 ms.
 2024-09-19 14:41:59 +03:00
Bananymous 8e08046519 Kernel: Add asserts about having locked TTY's write lock 
This for some reason fixes booting on real hardware? :D
 2024-09-18 00:56:48 +03:00
Bananymous 999eb53364 Kernel: Release debug lock if its locked during kernel panic 
Also kernel panic now prints if it had lock
 2024-09-18 00:56:02 +03:00
Bananymous f7e549e412 Toolchain: Run `strip` after installing toolchain 
This drops installed toolchain size to around fifth :D
