This project allows the virtual machine to access a persistent block device. This means
a user can format and partition this device inside it´s virtual machine. Because this disk
is then stored in the HTML5 local storage, a return to the emulator´s web page allows a
user to reopen the block device. All data stored on the disk can therefore be read again.
Schematically, the process works in the following way:
A block device driver is added to the Linux kernel. This allows a user to operate with
same I/O ports as a floppy disk. The device driver itself uses a temporary testing major
device node, id 250. Theoretically, it allows dynamic device node allocation, but I have
not tested this.
quite slow. I therefore decided to cache the total ´disk´ in memory, because it´s about
1M anyway. Writes are cached as well, and are ´flushed´ once the driver has transferred
a complete sector.
