Re: [ES40-developers] Misc Patches

[Vanderhoeven, C. (Camiel) <c.v...@mi...>]

Hi Brian,

This looks promising. I'll start applying your patches when I get home.

There is one thing though, I think that the floppy-controller should use
CDisk class devices for its drives. That requires a modification to the
CDiskController class and its dependant classes (CDiskController should
no longer have PCIDevice as a base class (because the Floppy Controller
is not a PCI device), and the Symbios and IDE controllers should inherit
from PCIDevice directly). This is something I meant to do a while ago,
so I'll start implementing that as well.

Thanks Brian!

Camiel.

Here's a few patches for things I've been working on:


1) system.diff

* if DUMP_MEMMAP is defined, es40 drops out its memory map in the order
that it is searched:

ES40 Memory Map

00000801fc0003f8        8 serial0(serial)/0

* When changing/defining memory regions, a simple bounds check is
performed, which prints out warnings if there appears to be an overlap:

WARNING: Start address for pci0.15(ali_ide)/2049
(00000801fc0003f4-00000801fc0003f7)
  is within memory range of pci0.7(ali)/0
(00000801fc0003f0-00000801fc0003f5).
WARNING: End address for pci0.15(ali_ide)/2049
(00000801fc0003f4-00000801fc0003f7)
  is within memory range of pci0.7(ali)/1
(00000801fc0003f7-00000801fc0003f7).


2) floppy.diff

This covers DMA.* FloppyController.* and PCIDevice.h changes to make the
floppy sort of work.  It won't boot from it and I can't figure out why.
It is hardcoded to use disk1of3 from NetBSD 4.0 and is really messy, but
it is a start.

P00>>>boot dva0
(boot dva0.0.0.1000.0 -flags A)
Block 001E2000 is not in any zone, call pc aa524 Block 001E6000 is not
