Lots of hacking: - Turn Keyboard into a CharacterDevice (85,1) at /dev/keyboard. - Implement MM::unmapRegionsForTask() and MM::unmapRegion() - Save SS correctly on interrupt. - Add a simple Spawn syscall for launching another process. - Move a bunch of IO syscall debug output behind DEBUG_IO. - Have ASSERT do a "cli" immediately when failing. This makes the output look proper every time. - Implement a bunch of syscalls in LibC. - Add a simple shell ("sh"). All it can do now is read a line of text from /dev/keyboard and then try launching the specified executable by calling spawn(). There are definitely bugs in here, but we're moving on forward. 2018-10-23 10:12:50 +02:00			`#pragma once`

Add memcpy() and strcmp() to LibC. 2018-10-26 13:32:13 +02:00			`int strcmp(const char, const char);`
			`void memcpy(void, const void, size_t);`
Implement errno in LibC. This also meant I had to implement BSS (SHT_NOBITS) sections in ELFLoader. I also added an strerror() so we can print out what the errors are. 2018-10-25 12:06:00 +02:00			`const char* strerror(int errnum);`
