apio	8e8706be27	sh: Use try_move instead of try_set ... Looks like Vector does not like being copied. I'll have to look into that later...	2023-04-07 11:52:59 +02:00

apio	cb1ef3e404	libc: Add (v)fprintf and make (v)printf use that ... Let's free libc of console_write!	2023-03-18 20:11:19 +01:00
apio	629ed9e43b	libc: Start switching to /dev/console for console IO and add a proper init	2023-03-18 19:23:18 +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	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	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	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
