apio	8c72e9a49a	kernel: Add an exec() system call ... Doesn't support arguments or environment for now.	2023-03-16 22:44:58 +01:00
apio	3cc2e4b2a4	app: Use C FILE instead of POSIX fd, and switch back to /etc/motd	2023-03-12 17:36:56 +01:00

apio	b54a7f3a80	kernel+libc: Add O_* flags and parse them in open() ... O_RDONLY, O_WRONLY, O_RDWR, O_TRUNC, O_CREAT and O_EXCL are fully implemented. O_APPEND is partially implemented. Other flags are not here yet.	2023-03-12 14:43:58 +01:00
apio	c0a7f6776f	kernel+libc: Add getpid()	2023-03-11 22:19:58 +01:00
apio	8fa72f3cf0	kernel+libc: Implement read()	2023-03-11 18:02:50 +01:00
apio	810c4bc257	kernel+libc: Start interfacing with the VFS from userspace (open & close) ... This commit adds open and close syscalls to the kernel, and adds matching wrappers to libc. No read/write support, so file descriptors are kind of useless for now.	2023-03-11 17:45:20 +01:00
apio	9afff7c544	kernel: Add a fun splash screen during boot :) ... Mostly for fun. Has a lot of delay in order to see the actual splash screen.	2023-02-27 16:23:51 +01:00
apio	e676fb8299	libc: Add a wide range of time manipulation functions, including reentrant variants	2023-01-13 21:06:27 +01:00

apio	d864bda751	libc: Add (de)allocate_memory wrappers located in sys/mman.h	2023-01-13 19:08:02 +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	c82ed5df01	Enable -Os on all targets	2023-01-10 18:13:21 +01:00
apio	7e377ef712	Implement printf()	2023-01-07 01:49:26 +01:00
apio	7fb2807d0c	libc: Implement time() using clock_gettime(). ... The cool POSIX kids use clock_gettime() now because it has NANOSECONDS (and different clocks!), but ANSI C prefers this function. We can still implement it based on clock_gettime(), we just have to discard the NANOSECONDS.	2023-01-07 00:27:23 +01:00
apio	a8a64863c8	kernel, libc: Add clock_gettime()	2023-01-07 00:21:08 +01:00
apio	80f5c790f8	Implement string formatting into libc :) ... Of course, using <luna/Format.h> makes it so simple. No need for duplicate code!	2023-01-06 20:15:43 +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	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
