apio	329e8ab182	luna/Heap: Scrub reallocations properly	2023-01-16 19:50:35 +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	da805eec83	Describe what check() and expect() are	2023-01-14 10:59:30 +01:00

apio	7462b764d8	Kernel: Add __cxa_atexit iomplementation	2023-01-13 18:56:05 +01:00

apio	9454b65682	allocate_memory: Respect PROT_NONE	2023-01-12 17:59:17 +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
apio	0e1e15e85a	Result: Construct a Result from an Option using from_option()	2023-01-11 23:02:42 +01:00

apio	d150c55143	TarStream: Support mode	2023-01-11 18:42:50 +01:00
apio	82b555cf5c	TarStream: Refactor the API to get rid of that awful method in Result ... That method being try_set_value_with_specific_error()	2023-01-11 17:30:53 +01:00
apio	6cf042e65e	Result: Remove m_has_value, rely on Option::has_value()	2023-01-11 17:09:32 +01:00
apio	67ebb00bd3	Option, Result: Introduce try_move_value(), which is the release_value() equivalent of try_set_value()	2023-01-11 17:06:17 +01:00
apio	84c82a4e75	luna, kernel: More constness	2023-01-10 19:31:41 +01:00
apio	5aa667c776	luna: Make OwnedStringView::clone() just call from_string_literal()	2023-01-10 19:03:00 +01:00
apio	3ac3d54788	luna: Make check() and expect() output errors in userspace	2023-01-10 19:02:16 +01:00
apio	c82ed5df01	Enable -Os on all targets	2023-01-10 18:13:21 +01:00
apio	feaf9ed19b	Update README.md	2023-01-09 18:16:39 +01:00
apio	c83f6c03b5	Bitmap: Add a 'find_and_toggle' method ... Just like find(), but toggles the value when finding it. Avoids doing this manually in MemoryManager and KernelVM.	2023-01-09 18:08:50 +01:00
apio	4287ec6cb0	Bitmap: Introduce a new method 'find' and use it in MM and KernelVM ... This method looks for the first bit with a value, optionally from a starting index, and returns its index. This should be (haven't benchmarked) way faster than the manual way, AKA what MM and KernelVM were doing. This is due to this method using bit and byte manipulation tricks instead of just calling get() until getting the desired result :)	2023-01-09 17:59:52 +01:00

apio	8de59138ef	We are platform-agnostic now (kind of) ... Still tied to x86_64, but because there's no other platform implemented. Also making this commit just to test CI with the new toolchain.	2023-01-07 21:42:57 +01:00
apio	0c5a84f932	toolchain: Update to binutils 2.39 ... CI will fail, it's normal. Wait for me to build a new toolchain for it.	2023-01-07 21:23:01 +01:00
