apio	ea89b92675	Store a bit more stuff in a thread :)	2023-01-05 21:50:53 +01:00
apio	31ea030c7f	MMU: Add functions to create and delete userspace page directories	2023-01-05 21:50:26 +01:00
apio	c53bba0392	MemoryManager: Add an unmap_weak_and_free_vm() helper function ... This function mirrors unmap_owned_and_free_vm(), but using weak unmapping (does not free the underlying physical memory)	2023-01-05 21:50:06 +01:00
apio	d3c414af4e	ELFLoader: Do not keep track of segments ... This reduces calls to kmalloc() since segment data is heap-allocated, and the segments loaded will be deleted when deleting the page directory.	2023-01-05 21:46:03 +01:00
apio	f0e14cf7e9	Update year range in LICENSE :)	2023-01-02 13:08:42 +01:00
apio	5854e5e530	Add newlines at end-of-file	2023-01-02 13:07:29 +01:00
apio	aab3a0a840	Update settings.json	2023-01-02 13:07:13 +01:00
apio	3442970678	Add vscode configuration	2023-01-02 13:00:22 +01:00
apio	df8f9c6cf6	SharedPtr: adopt_shared_from_owned	2022-12-31 12:02:15 +01:00
apio	831711ab7e	TypeTraits: Remove const, volatile, and reference	2022-12-31 11:50:30 +01:00
apio	e2e21923d7	Result: Implement operator=()	2022-12-30 19:06:47 +01:00
apio	4081186b27	Heap: Rewrite kmalloc to use Option<HeapBlock*> instead of nullable pointers to iterate over the heap ... At some point, this should be done inside LinkedList itself, but we have no such thing as break in for_each(). It's iterate over everything or nothing. This also requires operator= in Option, might be also added to Result in the future.	2022-12-30 19:02:25 +01:00
apio	3a3968b268	Result: Add nonnull_or_error()	2022-12-30 18:46:27 +01:00
apio	973e39a255	LinkedList: Move nonnull_or_empty_option to Option.h so everyone can use it	2022-12-30 18:46:18 +01:00
apio	28f53f9ccf	LinkedList: Rename the nonnull_or_error() helper to a more accurate nonnull_or_empty_option()	2022-12-30 18:44:37 +01:00
apio	1f36ecd044	LinkedList: Make expect_first() and expect_last() show a more accurate error description on panic ... Instead of showing a generic "Option::value() called on an empty Option" with no useful source location, you will get something like "check failed: m_start_node at LinkedList.h:139"	2022-12-30 18:43:39 +01:00
apio	24773fbece	kernel/main: Remove reference to 'extern const BOOTBOOT bootboot'	2022-12-30 18:38:50 +01:00
apio	74aa30a44f	Init: Call efficient_halt() on magic number mismatch instead of busy-looping	2022-12-30 18:36:22 +01:00
apio	9569385691	Remove unused include	2022-12-30 18:32:44 +01:00
apio	400d0395a2	Result: Avoid double-checking when calling through to the underlying Option	2022-12-30 15:00:02 +01:00
apio	8e59a0a79f	CMakeLists improvements	2022-12-30 11:48:18 +01:00
apio	7952d1d8a0	x86_64: Add basic keyboard support with an ASYNC DRIVER	2022-12-26 19:59:18 +01:00

apio	a1eca479d5	x86_64: Add a getter for the initial page directory	2022-12-26 12:57:25 +01:00
apio	2600acc96c	Thread: Add init_regs_user()	2022-12-26 12:46:07 +01:00
apio	7efb79dd26	LinkedList: Check for nullptrs in detach_from_list()	2022-12-26 12:45:49 +01:00
apio	7e62ee66be	Change heap.first().has_value() to the cheaper heap.count()	2022-12-26 12:24:39 +01:00
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	f71ccde833	Add an overload for aligned deletes which just calls the normal operator delete	2022-12-24 11:49:12 +01:00
apio	f2cc797599	Add a simple ELF loader	2022-12-23 13:09:21 +01:00
apio	e5ae2b0435	TarStream: Make read_contents and friends const	2022-12-23 13:08:31 +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	74235c2c99	Update README.md	2022-12-23 11:06:59 +01:00
