$NetBSD: TODO,v 1.3 2000/01/23 20:08:00 soda Exp $
$NetBSD: TODO,v 1.4 2000/01/23 21:01:48 soda Exp $
To do list (not in any particular order).
o Improve pmap_zero_page and pmap_copy_page. Speed and flushing.
o Move the RO and WIRED attribute from the pte to the pv table.
This saves four instructions in the tlb miss handler.
InWork: Have a test version. The system hangs after a while. Not solved yet.
Also, is it worth the effort to remove 4 instr. in TLB-miss handler?
o Update MAKEDEV to create all devices correctly.
o Boot. Standalone boot program instead of booting the kernel directly?
o Create boot package for distribution.
o sigsetjmp/siglongjmp missing....
o Add more videomodes to pccons driver. 50kHz and 64kHz monitors?
InWork: This seems to be hard. Need more info on the chip.
This seems to be hard. Need more info on the chip.
o Find out why bitmap load to S3-928 flashes screen.
Know why (enable linear mode). Need S3 info.
o Would be nice to have Motif...
o ELF shared libraries......
o GDB. The current one does not work correctly with current toolchain.
o ISA driver. ISA dma, interrupt etc.
Know why (enable linear mode). Need S3 info.
o Can we have 32 double registers?
o 64bit kernel/userland
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
- eliminate OpenBSD compat #define symbols
o fix kernel start address
o merge new wscons
o parse ARC BIOS configuration information and use it
o fix implementation of DELAY(), clean up clock implementation
o if_sn.c ether address handling clean up
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
Lots of other things.....

# mode to use, the next set of four bits the DMA mode and the third set the
# UltraDMA mode. For each set of four bits, the 3 lower bits define the mode
# to use, and the last bit must be 1 for this setting to be used.
