Kernel: Implement OffsetDiskDevice to prepare for partition support This implements a passthrough disk driver that translates the read/write block addresses by a fixed offset. This could form the basis of MBR partition support if we were to parse the MBR table at boot and create that OffsetDiskDevice dynamically, rather than seeking to a fixed offset. This also introduces a dependency in the form of grub. You'll need to have 32-bit grub binaries installed to build the project now. As a bonus, divorcing Serenity from qemu's kernel loading means we can now technically boot on real hardware. It just... doesn't get very far yet. If you write the `_disk_image` file to an IDE hard drive and boot it in a machine that supports all the basic PC hardware, it will start loading the kernel. 2019-06-02 08:58:59 +00:00

Kernel: Parse cmdline for root filesystem e.g. root=/dev/hda1 This introduces very basic handling of the kernel command line to choose the root filesystem at startup. Given that we currently only support a single IDE hard drive, it's hard-coded to look for `/dev/hda` at the start of the argument. If there is nothing following this, or if the parameter is empty, init_stage2 will try to load the ext2 filesystem from the start of the device. This is intended to be the default behaviour when running development builds, as it is faster to set up and doesn't require a working grub installation. If `/dev/hda` is followed by a number, init_stage2 will try to read an MBR partition header from the drive, then load the requested partition. It will reject non-numeric trailing data, and anything outside of partitions one through four. 2019-06-04 12:03:35 +00:00			`multiboot /boot/kernel root=/dev/hda1`
