Bananymous 04c715d314 BuildSystem: Build all libraries in root build directory 
I could not figure out how to use cmake's rpath to build libraries with
DT_NEEDED only containing the library name, not a relative path.
 2024-09-02 21:31:08 +03:00

 2024-08-30 15:33:02 +03:00
Bananymous 8da2f12ba6 Kernel: Only load program headers of interpreter if its present 
I was loading program headers of both executable and interpreter but
that is incorrect. The interpreter will itself load the program headers
of the executable.

Bananymous 2ce7205c80 Kernel: Add command line option to disable debug printing

Bananymous fb35f06cf5 Kernel: Add better support for bootloaders loading the kernel 
Before I assumed that bootloaders loaded the kernel at physical address
0, but this patch kinda allows loading to different addresses. This
still doesn't fully work as kernel bootstrap paging relies on kernel
being loaded at 0
 2024-08-22 14:48:21 +03:00
Bananymous abc788c756 Kernel: Improve output message when dumping all syscalls 2024-08-22 14:48:21 +03:00
Bananymous 63b616dc2e Kernel: Hack non-blocking support for sockets

the same socket try to read data at the same time
 2024-08-22 14:48:14 +03:00
Bananymous 72f3fe0b12 LibC: Add empty files sys/param.h and sys/file.h 
For some reason some ports include these files even when they detect
that they are not available
 2024-08-22 14:47:59 +03:00
Bananymous cba12efeb1 Kernel: Ignore optional_actions in SYS_TCSETATTR 
Currently all terminals are syncronous, so the actions don't do anything
 2024-08-22 14:47:54 +03:00

were idling
