apio	8cb9c14b1e	luna/Format: Make output_(pure_)integer_data take a const reference to vstate	2023-01-22 17:36:02 +01:00
apio	7f8a8cdcaf	kernel, libc: Add an usleep() system call and use that to implement usleep() and sleep() in libc	2023-01-22 15:00:20 +01:00
apio	d5b1d72396	x86_64/MMU: Map the kernel page directory to virtual memory ... This avoids depending on the kernel address space to create a new userspace one, since there is no physical memory access. This was fine for a single process, since its address space was created from the kernel one and no more address spaces were created, but for two or more, this started to become problematic, since we would create one address space while being in another process's address space, which has no direct mapping of physical memory.	2023-01-22 14:46:03 +01:00
apio	a7a38d3433	Bitmap: Add a fallible variant of match_region() that does not crash if arguments are out of range ... This lets us call deallocate_memory() with any address and it will not crash.	2023-01-22 14:25:51 +01:00
apio	cb59a4e0e3	libc: Add assert.h	2023-01-22 12:51:30 +01:00

apio	944d32de36	Bitmap: Introduce new malloc-aware initialization functions ... Lets us call resize(new_size) instead of initialize(realloc(location, new_size), new_size)	2023-01-21 23:16:50 +01:00
apio	0e607c2fef	Bitmap: Declare more variables as const ... I miss Rust's immutability-by-default...	2023-01-21 23:04:21 +01:00

apio	1b807a4e06	arch/Timer: Make sure ARCH_TIMER_FREQ is a power of two ... (avoid division and modulo, division is slow) Fortunately, GCC will optimize divisions by powers of two to simple bitwise shifts :)	2023-01-16 19:43:05 +01:00
apio	d0600f5714	luna: Make Utf8StringEncoder short-circuit instead of failing when hitting the length limit	2023-01-14 12:07:08 +01:00
apio	e3ef29e80d	libc: Implement wcstombs()	2023-01-14 11:59:08 +01:00
apio	00ee8314b3	luna: Make Utf8String{De,En}coders return the number of bytes written ... This means we can avoid a call to code_points() in mbstowcs(), which would parse a string twice.	2023-01-14 11:55:19 +01:00

apio	586ca19b62	Add a VERY BASIC and hacky way of allocating memory from userspace ... Only supports one-page allocations and doesn't have libc wrappers, which means it has to be invoked using syscall().	2023-01-11 23:02:42 +01:00
