I am working on a port to (ex-Acorn) RISC OS, which currently gets as far as
rescue mode.
RISC OS is supplied in ROM or flash with many systems, including desktop
systems made by Acorn and it's sucessors, various set-top boxes, and the Bush
Internet TV. I have used upper case thoughout for RISC OS as riscos is a
different operating system.
Things to do:
Discs and partitions.
RISC OS native filesystem access.
Network support (using BSD sockets).
Colour and graphic console support.
An interface for writing to files.
A file copy command, to use when upgrading grub.
Serial port support.
Security (disabling keyboard drivers during boot)
Access to RISC OS commands.
A memory defragmenter.
And some OS loaders of course.
How should console errors be handled? Currently they are fatal, and won't
happen unless the console is redirected (assuming USB drivers don't
complain).
Currently in the design of GRUB 2 there is an incorrect asumption that filing
systems are either based on disks or networks. I propose to rectify this
whilst keeping code size down by:
Creating a struct grub_fs_device_driver, which contains a pointer to either
struct grub_disk_dev or struct grub_net_dev, and maintain a single linked
list of disk drivers, net drivers, and standalone filing systems.
Convert struct grub_device from pointers to a unoin to simplify the code by
removing memory allocations.
