To do list (not in any particular order).
o Move the RO and WIRED attribute from the pte to the pv table.
This saves four instructions in the tlb miss handler.
o Boot. Standalone boot program instead of booting the kernel directly?
o Find out why bitmap load to S3-928 flashes screen. (X server)
Know why (enable linear mode). Need S3 info.
o Can we have 32 double registers?
o 64bit kernel/userland
o repair DeskStation and Algor support
- 64bit device physical address space for Tyne (see OpenBSD pmap.c)
- requires bus_dma
o source code structure is quite obsolete,
general clean up is needed as nisimura-san suggested.
especially:
- introduce struct platform and remove ugly ``switch (cputype)''
in many places.
- implement and use bus_dma
- clean up bus_space implementation, remove inb/outb
o fix kernel start address
o merge new wscons
o parse ARC BIOS configuration information and use it
o omit __BROKEN_CONFIG_UNIT_USAGE
o omit __SWAP_BROKEN in <mips/types.h>
o fix implementation of DELAY(), clean up clock implementation
o asc.c scsi clock/NCR53CF94 handling clean up
o if_sn.c ether address handling clean up
o com_lbus.c clock handling clean up
o implement NCR 53c700(?) driver for NEC RISCserver 2200
based on amiga siop driver?
o use MI driver
- use MI ncr53c9x driver instead of home grown asc
- use MI bha driver instead of home grown btl
- make sonic driver MI, and share it with mac68k, newsmips/apbus
- make fd driver MI, and share it with i386
(contact christos about MI fd driver)
- make pccons MI, and share it with i386,
or simply eliminate pccons
o easy part
- ARC boot device name -> NetBSD root device conversion
- and missing MI devices
lkm, tun, vcoda, raidframe, ...
- way to specify serial console
o resolve "XXX"
Lots of other things.....
