TODO revision 1.8 
      1 $NetBSD: TODO,v 1.8 2000/03/04 07:09:09 nisimura Exp $
      2 
      3 To do list (not in any particular order).
      4 
      5     o	Move the RO and WIRED attribute from the pte to the pv table.
      6 	This saves four instructions in the tlb miss handler.
      7 
      8     o   Boot. Standalone boot program instead of booting the kernel directly?
      9 
     10     o   Find out why bitmap load to S3-928 flashes screen. (X server)
     11 	Know why (enable linear mode). Need S3 info.
     12 
     13     o   Can we have 32 double registers?
     14 
     15     o	64bit kernel/userland
     16 
     17     o	repair DeskStation and Algor support
     18 
     19 	-   64bit device physical address space for Tyne (see OpenBSD pmap.c)
     20 
     21 	-   requires bus_dma
     22 
     23     o	source code structure is quite obsolete,
     24 	general clean up is needed as nisimura-san suggested.
     25 	especially:
     26 
     27  	-   introduce struct platform and remove ugly ``switch (cputype)''
     28 	    in many places.
     29 
     30 	-   redesign interrupt handler framework to be flexible for
     31 	    possible variations; must be sane and useful for R4030/R4230
     32 	    'local' devices and any combinations with ISA/EISA/PCI
     33 
     34 	-   implement and use bus_dma, keeping in mind TLB assisted VDMA
     35 	    that R4030/R4230 chip provides
     36 
     37 	-   clean up bus_space implementation, remove inb/outb
     38 
     39 	-   try to interporate HZ; may be possible for R4030/R4230 system
     40 	    or 'hardclock() by R4000' system.  Clock resolution of 100Hz
     41 	    without any interporation is substandard
     42 
     43     o	fix kernel start address
     44 
     45     o	merge new wscons
     46 
     47     o	parse ARC BIOS configuration information and use it
     48 
     49     o	omit __BROKEN_CONFIG_UNIT_USAGE
     50 
     51     o	omit __SWAP_BROKEN in <mips/types.h>
     52 
     53     o	fix implementation of DELAY(), clean up clock implementation
     54 
     55     o	asc.c scsi clock/NCR53CF94 handling clean up
     56 
     57     o	if_sn.c ether address handling clean up
     58 
     59     o	com_lbus.c clock handling clean up
     60 
     61     o	implement NCR 53c700(?) driver for NEC RISCserver 2200
     62 	based on amiga siop driver?
     63 
     64     o	audio driver
     65 
     66     o	use MI driver
     67 
     68 	-   use MI ncr53c9x driver instead of home grown asc
     69 
     70 	-   use MI bha driver instead of home grown btl
     71 
     72 	-   make sonic driver MI, and share it with mac68k, newsmips/apbus
     73 
     74 	-   make fd driver MI, and share it with i386
     75 	    (contact christos about MI fd driver)
     76 
     77 	-   make pccons MI, and share it with i386,
     78 	    or simply eliminate pccons
     79 
     80 	-   LKM
     81 
     82     o	ARC boot device name -> NetBSD root device conversion
     83 
     84     o	and missing MI devices
     85 		ses?, lkm, vcoda, ...
     86 
     87     o	way to specify serial console
     88 
     89     o resolve "XXX"
     90 
     91 Lots of other things.....
