SMBus Controller, LPC Interface and USB Host info are “Unknown” on Menlow Platform when using lspci to watch

[Jing Wang]

Bug detailed descriptions:
--------------------------
On 7/28 ABAT_USB_Image

When I use lspci to show PCI interface inforamtion, I don't see SMBus, LPC and EHCI, UHCI
info as common Intel platform. Instead, there are quite lot of "Unkown Intel Device". I
guess this is caused on BIOS. Anyway, file a bug here and wait for new BIOS version

Reproduce steps:
----------------
1. lspci
2. grep SMBus (LPC, EHCI, UHCI) ...

Current result:
----------------
Unknown Intel Devices

Expected result:
----------------
USB UHCI Controller
USB EHCI Controller
SMBus Controller
LPC interface

Basic root-causing log:
----------------------
Maybe BIOS

This is a bug in lspci in that it needs to be patched to recognize the latest
Intel HW. This needs a patch that's submitted upstream to the maintainers of
lspci. I believe Jacob has a fix or knows of a fix for this.

This isn't a bug in the kernel.

I suggest make this bug open, so we can track it more easily.
Jacob, where do u submit the patch? Ubuntu or lspci project?

Jay: I'm re-assigning this bug to you. You fix this by creating & releasing a patch to the upstream lspci project. Patch is released upstream at the time Menlow is launched. In the interim period, while we're waiting for the upstream project to accept the patch. we need to import the lspci package into moblin.org and making the the changes there. You will then need to push the changes to Ubuntu. You may want to skip the step of pushing to Moblin if Ubuntu will take the patch immediately.

run evironment: crown_beach c0 , BIOS v66 , on 01/28 image stable release
the bug still exists

Test Steps:
1.Scan /sys/bus/pci to see poulsbo related info
2. Refer to /usr/share/misc/pci.ids, which contail a list of known PCI ID
3.Check if PCI ID for poulsbo is correct

the result is the poulsbo info does not exist in /usr/share/misc/pci.ids, so the test still fail

[Jay Chetty (jaychetty)]

While we are waiting for the upstream pciutils to pick up the new ID the ubuntu-mobile PPA has been updated with version of pciutils that has the latest snapshot of PCI IDs and Plusbo ID as well.

Create a image with 'menlow-lpia-ubuntu-hardy-ppa' platform and you will see the updated PCI IDs.

[alek du (alek-du)]

It depends on when upstream pciutils to pick up the new ID. While the ppa version pciutils already got fixed.

[Jay Chetty (jaychetty)]

The upstream pciutils has incorporated the new IDs. So this bug could be closed as fixed?
The new PCI ID can be found here http://pci-ids.ucw.cz/iii/?i=8086

[alek du (alek-du)]

Please build a hardy ppa image to verify that.
