[Wilfred Smith]

Has anyone done a port 80h snoop history module? If so, pointers appreciated. Also interested in constructive peanut gallery thoughts and considerations...

Hello Wilfred Smith,

You can refer the module phosphor-host-postd and add file recipes-phosphor/host/phosphor-host-postd_%.bbappend for changing your snoop device.
(ex: SNOOP_DEVICE = "npcm7xx-lpc-bpc0")

Then, you can execute "snooper" program in shell prompt and you will see the POST code be printed on console.
You can refer the attach file about screenshot for the result of snooper. Thanks.

Best regards,
Tim

Tim, Many thanks. Are you also providing the ability to track the history of the port 80h snoop values? If not, are you aware of someone else having done so?

Hi Wilfred,

Yes, I also modified example code to track the history of the port 80h snoop values.
The history will be saved to file with timestamp name for Host ON, OFF, and enter BIOS conditions.
T
his patch is just an experiment hard coded some specific Port80H codes for monitoring BIOS we used.
These code should be configurable in a mature implementation, such as GUI/REST API entries for downloading/viewing these logs, but not done due to priority change.

The link of patch for you refer it. Thanks.

Best regards,
Tim

That's nice, I did't know it existed.

The ability to store POST codes has been on my backlog for quite a
while. I'd be happy to review patches/proposals to integrate the
functionality into OpenBMC.

I think Kuiying had some patches to enable this:
https://gerrit.openbmc-project.xyz/c/openbmc/phosphor-post-code-manager/+/18503,
but it's not merged yet. +Kuiying and Jason might have more
information.
