$NetBSD: TODO,v 1.4 2001/07/06 20:12:34 scw Exp $

|
NetBSD/mvme68k's "ToDo" List (In no particular order)
|
|
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
|
|
|
|
These are `difficulty' rated on a scale of 1-10, where `1' is easy.
|
|
|
|
|
|
1. Flesh out the "Memory Controller" (memc) driver (3)
|
|
|
|
2. Enhance the PCC2/MC2 driver to support its "Memory Controller"
|
|
functionality on older MVME1x2 boards. (2)
|
|
|
|
3. Support for "Industry Pack" modules (4)
|
|
(Need to come up with an MI interface for this, since various
|
|
other non-mvme68k SBCs have IP sites too)
|
|
|
|
4. Switch over to the MI mk48txx TOD-chip driver (1)
|
|
(I already have most of this done)
|
|
|
|
5. Support for the NVRAM part of the above chips (2)
|
|
(With a userland tool to read/write configuration details?)
|
|
|
|
6. Related to #5, add code to locore.s to verify the configuration
|
|
area of NVRAM is kosher (using a checksum) before using any values
|
|
from it (2)
|
|
(eg. at this time, bogus Offboard RAM details cause crashes)
|
|
|
|
7. Support for FLASH memory on MVME1x2 boards (3)
|
|
(Will probably need a userland tool of some sort)
|
|
|
|
8. Add support for the in-kernel FP emulator, so we can run on MVME
|
|
boards with the MC680LCx0 CPU variant (4)
|
|
(Easy enough to do; slightly harder to test)
|
|
|
|
9. Add "Bounce Buffers" to the VMEbus slave code (8)
|
|
|
|
10. Support the MVME boards as a slave in A16 address space (8)
|
|
(To be useful, this really needs "Bounce Buffer" support)
|
|
|
|
11. Enhance the MI VMEbus interface to provide generic GCSR access (6)
|
|
(Speak with Matthais Drochner <drochner@netbsd.org> about this one)
|
|
|
|
12. Enhance the VMEChip/VMEChip2 drivers to support #11 (3)
|
|
|
|
13. Fix the case where VMEbus RAM is mapped through a translated
|
|
address space on MVME boards with the VMEChip2 (2)
|
|
|
|
14. [DONE]
|
|
Add/Flesh out evcnt(9) support where useful (1)
|
|
|
|
15. [DONE. See osiop(4)]
|
|
The siop driver *badly* needs to be bus_space(9)'d, and made MI (5)
|
|
(Apparently, Manuel Bouyer (bouyer@netbsd.org) is working on this)
|
|
|
|
16. The sbic driver *badly* needs re-written from scratch, and made MI (5)
|
|
(This will be done when Frank van der Linden <fvdl@netbsd.org>
|
|
imports the PC98 code into the tree; it comes with a very nice
|
|
wd33c93 driver ;-)
|
|
|
|
17. Switch the install tools over to sysinst (3)
|
|
(Should be fairly easy, although sysinst doesn't do `tapes', so
|
|
there's a bunch of code to write)
|
|
|
|
18. [DONE]
|
|
Use hardware-assisted softints (3)
|
|
(What to do on MVME1x2 boards with no VMEChip2?)
|
|
|
|
19. Make the ZS driver *properly* MI (4)
|
|
(I already have patches for this. Unfortunately, it affects just
|
|
about every NetBSD architecture...)
|
|
|
|
20. Implement the MD parts of __HAVE_SYSCALL_INTERN (2)
|
