I used the same kernconf I used for the kernel I'm using now.
A trip to /usr/src and a search with find(1) confirms the file doesn't
exist. How would I best proceed?

Thank you for any direction on this.

Great clue here, Gary. Thanks!

You need device smbus in your kernel config file so that it will be created.

Right. As I mentioned. I'm using the same kernconf I used to build the kernel
I'm currently using. dmesg(8) reports:
smbios0: <System Management BIOS> at iomem 0x40084000-0x4008401e
smbios0: Version: 3.3, BCD Revision: 3.3

smbus0: <System Management Bus> on ichsmb0

So it appears that my system uses it. Now, if I can only get my OS to
provide it. ;)

Thanks for that great clue and all your time here, Gary!

ichsmb0: <Intel Alder Lake SMBus controller> port 0xefa0-0xefbf mem 0x6001144000-0x60011440ff at device 31.4 on pci0

I don't have smbus in my file and as a result I don't have smbus_if.h on
my system.
