lspci

[Donald McLachlan]

Background info follows, but my questions are:

- Why does vxWorks say the card's I/O addresses are at 7001 and 7401 when
Linux says they are at 7000 and 7401?
- Also, why 2 addresses 700X and 740X; begin and end, or aliasing?
- Both report memory address f9000000. SeaLevel says the registers
are only available via I/O ... so what's this memory?

Thanks,
Don

I'm running booting vxWorks from a floppy on a PC that was used for linux ...
so if I boot from the hard disk I have linux.

Using the Linux lspci command I get:

> lspci -v -d 0x135e:0x5102
00:0d.0 Serial controller: Sealevel Systems Inc: Unknown device 5102 (rev 01) (prog-if 02 [16550])
Subsystem: Sealevel Systems Inc: Unknown device 5102
Flags: medium devsel, IRQ 12
Memory at f9000000 (32-bit, non-prefetchable)
I/O ports at 7000
I/O ports at 7400

Using vxWorks command from the target shell I get:

Hi Donald,

your vxWorks' output says the same as linux. The 1 at the end of 7001 and
7401 is the indicator of I/O-space.
Could the memory area at f9.. be a buffer ? Write 0xFFFFFFFF to it and read
back again. Look at the unset bits from low to high and you'll have the
width of your device's address decoder (which _might_ be the size of
device's buffer).
