apio	0a472000be	Fix CI by providing a host C++ compiler	2023-01-06 19:00:32 +01:00
apio	83651b4b90	CMake: Respect the ARCH env variable	2023-01-06 18:59:59 +01:00
apio	bdfe7dac17	libc: Remove crti.o and crtn.o ... Looks like these are now provided by the compiler.	2023-01-06 17:59:54 +01:00
apio	8838e2cf22	Bring back the OS-Specific Toolchain on restart :^)	2023-01-06 17:35:07 +01:00
apio	e37280b0e5	ELFLoader: Set both the read-write and execute flags if the section has both ... Not good for W^X, but the compiler decides to squash everything into a single program header :(	2023-01-06 17:34:24 +01:00
apio	87a4bc91d8	arch/x86_64: Nicer display for page faults that shows a human-readable version of the error code	2023-01-06 17:31:22 +01:00
apio	a01b56ed39	CString: Support strcpy(), strcat() and strchr()	2023-01-06 16:20:35 +01:00
apio	30555f8e5a	Skip these because CI needed a toolchain rebuild	2023-01-06 15:00:49 +01:00
apio	7acef24494	Make libc depend on crt{0,i,n}.o	2023-01-06 14:32:38 +01:00
apio	71414c0653	Explicitly set the link path to make it build on CI	2023-01-06 14:28:53 +01:00
apio	db1941140c	Explicitly include system headers to make it build on CI	2023-01-06 13:40:53 +01:00

apio	f1923ce5bd	Install headers before compilation	2023-01-06 13:35:57 +01:00
apio	129e3c434a	Switch to C for userspace, with a very bare-bones libc!!	2023-01-06 13:31:14 +01:00
apio	b27cefb9c5	SystemError: Define _LUNA_SYSTEM_ERROR_EXTENSIONS to compile properly in hosted envs	2023-01-06 13:30:49 +01:00
apio	293b979e75	ELFLoader: Do not crash on non-page-aligned sections	2023-01-06 13:30:17 +01:00
apio	fd8a0175d9	Add a syscall infrastructure (our baby program can print to the console now!)	2023-01-05 22:39:56 +01:00
apio	caa3fe8c45	MemoryManager: Add validate_userspace_string() ... A bit crude, should be replaced by a strdup_from_user() helper to avoid touching userspace memory directly. But it'll do for now.	2023-01-05 22:39:09 +01:00
apio	0ea9974512	First user process! ... Putting it all together, we have a user process that successfully calls sys_exit() w/o crashing.	2023-01-05 21:55:21 +01:00
apio	0aac6c888d	x86_64: Basic exit() syscall! ... User processes need to do something, amirite?	2023-01-05 21:53:48 +01:00
apio	a33a72915e	Scheduler: Creation, destruction and switching of userspace tasks :)) ... From a TarStream. Not optimal, but OK for the moment.	2023-01-05 21:52:26 +01:00
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	7efb79dd26	LinkedList: Check for nullptrs in detach_from_list()	2022-12-26 12:45:49 +01:00
