apio	73c58bd902	Init: Move platform_init() before MemoryManager::init() ... This enables NX before we actually use it. Wasn't causing problems with KVM on, but crashed with KVM off with a 'reserved bit set' page fault.	2022-12-26 12:12:55 +01:00
apio	0054777e7d	x86_64: Warn if NX is not supported	2022-12-26 12:11:10 +01:00
apio	08984e1673	x86_64: Create a has_flag() helper function and remove redundant clearing of reserved bits	2022-12-26 12:10:47 +01:00
apio	59d69f684f	x86_64: Add general protection fault handler	2022-12-24 11:49:47 +01:00
apio	f2cc797599	Add a simple ELF loader	2022-12-23 13:09:21 +01:00
apio	ad0f6546d7	Add a global initrd TarStream to make the initial ramdisk accessible everywhere ... It's also mapped into virtual memory instead of directly going into the physical location!!	2022-12-23 11:33:23 +01:00
apio	6ff92b1714	MemoryManager: Add get_kernel_mapping_for_frames() ... This function allocates a continuous range of VM and maps the physical frames passed to said VM range.	2022-12-23 11:30:49 +01:00
apio	9afaad8fed	Add dbgln() for the luna library	2022-12-22 18:00:35 +01:00

apio	042f999677	Heap: SCRUB IT ALL ... If your memory is all 0xacacacac there is a big probability you haven't initialized it.	2022-12-19 13:20:38 +01:00
apio	a11a5dec1f	DoublyLinkedList -> LinkedList	2022-12-19 12:43:23 +01:00
apio	1269a045bd	LinkedList: Add a convenience delayed_for_each() method. ... This is a special way of iterating over the list which permits removing items while iterating.	2022-12-19 12:41:25 +01:00
apio	5b72144fac	Add a handy consume() method to LinkedList	2022-12-19 12:35:08 +01:00

apio	0bdbffe0ca	Spinlock+LockedValue: Add try_lock() methods ... For when you want to lock a resource if possible but not get blocked if it is locked by another thread.	2022-12-18 20:37:26 +01:00
apio	283e641ece	Spinlock+LockedValue: Remove init() functions ... Let's set the default (unlocked) value of Spinlock's underlying atomic to 0, so even if the constructor is not called it stays like that.	2022-12-18 20:36:15 +01:00
apio	a63146a798	Show the date and time of build :)	2022-12-18 18:51:25 +01:00

apio	6c3b7672a0	Kernel: Demo the initrd using TarStream ... Yes, we're using the physical address. Not optimal, this is only for demo purposes.	2022-12-18 16:39:35 +01:00
apio	ffd3385d0d	TextConsole: decoder -> utf8_decoder	2022-12-18 14:42:53 +01:00
apio	36179155e1	Add UTF-8 support to TextConsole!! ... Not much support, since the font only covers codepoints from U+0000 to U+00FF, (Basic Latin & Latin Extended-A), but unprintable code-points are rendered as ONE box per code-point, instead of multiple garbage characters. So it's Unicode-aware, even if it can't print most characters.	2022-12-18 13:09:37 +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	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	2e24e09146	Convert MemoryMapIterator to Option	2022-12-16 19:47:20 +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	41b3c8adb2	Convert to_dynamic_unit to OwnedStringView and rename the old variant to to_dynamic_unit_cstr	2022-12-16 18:18:24 +01:00
