All of the expanded 'vendor', 'device', 'class' and 'subclass' information is
present in the non -v version of the command output. The numbers shown
earlier can be used to derive the text information:
class=0x010400
determines the class/subclass lines, using the table from here:
http://fxr.watson.org/fxr/source/dev/pci/pci.c#L1340
card=0xc0351044 chip=0xa5111044
these make up the vendor and device lines, using the list in
/usr/share/misc/pci_vendors (which is derived from the PCIDEVS.TXT
listing).
The last 4 hex digits of the card and chip lines are the vendor ID
while the first 4 are the device ID. The card is often given by
the vendor, while the chip identifies the actual part it uses to
implement functionality. For instance, a Netcomm ethernet NIC may
use a Realtek 8139 chip... so chip gives us the fact it's
essentially a generic Realtek chipset, while the card tells us the
vendor who manufactured the card & perhaps their name for it.
In short, there's no reason to have to transmit all the text names back to
any server -- this can all be resolved at the server end,
'k, looking at the above, and comparing it to what I'm getting from
pciconf -l, I'm missing something ... namely:
[EMAIL PROTECTED]:10:0: class=0x020000 card=0x0027a0a0 chip=0x813910ec
rev=0x10 hdr=0x00
Translates to:
[EMAIL PROTECTED]:10:0: class=0x020000 card=0x0027a0a0 chip=0x813910ec
rev=0x10 hdr=0x00
vendor = 'Realtek Semiconductor'
device = 'RT8139 (A/B/C/810x/813x/C+) Fast Ethernet Adapter'
class = network
subclass = ethernet
But, the last 4 hex of card/chip aren't teh same ... oh, wait, re-reading
what you stated, is it safe to assume that chip= can be ignored ... nope,
that doesn't follow either ... but I think I see it ...
For the above, vendor *should* be Aopen Inc, not Realtek Semiconductor ...
'k, so, for the above:
card=0x0027a0a0
- Aopen Inc (A0A0)
chip=0x813910ec
- Realtek Semiconductor (10EC)
- 8139 RT8139 (A/B/C/810x/813x/C+) Fast Ethernet Adapter (8139)
And the 0027 is actually meaningless in this case ...
So, what I'm looking for is vendor->device, but in some card= cases, there
won't be a 'Device' listed ...
As to class= ... what table am I supposed to be seeing at that URL?
