Add a simple IDEDiskDevice class that implements DiskDevice from VFS.

Process now maps regions immediately when they are allocated. This avoids having to do a separate MM.mapRegionsForTask() pass. Also, more Task => Process renaming that I apparently hadn't saved yet.

Add basic paging. Only identity maps the bottom 4MB as a start.
2018-10-18 00:13:55 +03:00
IDEDiskDevice.o \
Add a Console device and start refactoring screen output.
2018-10-21 22:59:43 +03:00
MemoryManager.o \
Add IRQHandler class that can be subclasses to handle an IRQ. Also move Keyboard to a class implementation using this pattern.
2018-10-22 13:58:29 +03:00
Console.o \
Move kprintf to its own file. It has nothing to do with VGA anymore.
2018-10-22 14:20:35 +03:00
IRQHandler.o \
Start adding a basic /proc filesystem and a "ps" utility.
2018-10-23 12:57:38 +03:00
kprintf.o \
Add gettimeofday() syscall and LibC wrappers gettimeofday() and time(). This only has second accuracy right now, I'll work out subseconds later.
2018-10-25 18:29:49 +03:00
ProcFileSystem.o \
Start working on virtual consoles/TTYs. This is a mess right now, but I'd rather commit as I go.
2018-10-30 15:59:29 +03:00
RTC.o \
TTY.o \
Move the scheduler code to its own class. This is very mechanical.

VirtualFileSystem class builds inside Kernel.

List the root directory after mounting /. So cool that it works! It's spewing out a bunch of terminal escape sequences that the OS console obviously doesn't support, but we'll get there too.
2018-10-17 12:47:14 +03:00

Print the contents of motd.txt on boot.

AK_OBJS = \
../AK/String.o \
Add a VFS::absolutePath(InodeIdentifier). This is pretty inefficient for ext2fs. We walk the entire block group containing the inode, searching through every directory for an entry referencing this inode. It might be a good idea to cache this information somehow. I'm not sure how often we'll be searching for it. Obviously there are multiple caching layers missing in the file system.

Implement loading of linked ELF executables. This took me a couple hours. :^) The ELF loading code now allocates a single region for the entire file and creates virtual memory mappings for the sections as needed. Very nice!

Canonicalize the path used by sh. With a bunch of LibC work to support the feature. LibC now initializes AK::StringImpl by default. It's now fine to use AK in LibC/Userland! :^)

Add a very hackish /proc/PID/stack. It walks the stack and identifies anything that looks like a kernel symbol. This could be a lot more sophisticated.

Make it run in QEMU. Looks like the problem was the weirdly-sized floppy image file. I guess QEMU was inferring the floppy disk geometry from the image size.
