kernel+apps+base+tools: Use Ext2 for the root partition file system
...
continuous-integration/drone/push Build is passing
init is now split into two parts: preinit, which lives in the initrd and prepares the root file system for init,
and the actual /usr/bin/init, which lives in the root partition and starts services and reaps zombies.
The kernel now looks for /bin/preinit instead of /bin/init as the executable for the init process.
All configuration files in initrd/etc have been moved to base/etc. (The plan is to have only moon and preinit in the initrd.)
Since the current Ext2 implementation is read-only (and it's on a CDROM so it would be read-only anyways),
/home/selene is a tmpfs (as well as /tmp), to allow for a writable home directory.
The system is slower now, but that's to expect since the Ext2 code doesn't use caching and the ATA code still uses PIO.

Just take the currently used directory.
2023-07-10 13:04:18 +02:00
503dc72686
kernel: Set kernel threads' initial active directories to avoid taking the first directory they use
...
This ends up being init's directory, which is fine when init's directory doesn't change...
but a little less fine when the init process calls exec()...
which is what it does in the new configuration I'm testing...

kernel: Rename UserVM to AddressSpace
...
continuous-integration/drone/push Build is passing
This is a more appropriate name now that it does more stuff than allocate virtual memory.
To be fair, the name was a bit awkward anyway. Should have been UserVMAllocator I guess.
2023-07-09 20:38:04 +02:00
5e564e9ae3
kernel: Move Thread::self_directory to UserVM
...
Since this is only used by user threads, UserVM is a convenient/related place to store the PageDirectory in a RAII manner.

The memset() happens a bit earlier, and we don't have to remap the
mapped virtual memory.

kernel: Separate a thread's page directory into two
...
continuous-integration/drone/pr Build is passing
The self directory, and the active directory. The active directory is the one the thread is currently using,
and the self directory is the one the thread owns.
This lets us keep track of both, which fixes ext2 executables crashing the system.
