apio	635437a4a4	luna: Add a new idiomatic way to mark unused parameters as used while keeping their names ... Just call ignore(...)	2023-01-25 21:14:44 +01:00

apio	de04c094e7	x86_64: Skip enabling WP for now until I find how to check for its availability	2023-01-23 20:06:45 +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	631cdd0204	x86_64/CPU: Skip null instruction pointers on stack trace generation	2023-01-16 20:44:45 +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	abbed13f27	Add a 'pure' variant of cstyle_format which is infallible ... If we cannot fail to output, it doesn't make sense to propagate errors. So if you're SURE there are no errors, use pure_cstyle_format(). If, however, output can fail, use cstyle_format(). This has a drawback of adding quite a bit of code duplication to Format.cpp. Some of it is dealt using templates, but some code still remains duplicate.	2022-12-17 12:38:22 +01:00
apio	9d6235e109	CPU: Add a pause() method	2022-12-17 10:45:55 +01:00
apio	59765aa334	Rename String.h -> CString.h ... Let's not confuse String.h with a managed string class, it's in fact the equivalent of the C stdlib's <string.h>	2022-12-16 20:40:04 +01:00
apio	814672c771	Remove some redundant error propagation ... Why can printing to the serial port or format onto a string fail? Even if cstyle_format returns Result<usize>, we shouldn't always follow suit.	2022-12-16 18:32:29 +01:00
apio	6cee208e62	Kernel: Enable -Wsign-conversion ... For real this time, turns out me, being dumb, added it to Luna instead of the kernel.	2022-12-08 15:09:32 +01:00
