Dear freebsd-{current,hardware}_at_, Let me a give a few guiding comments for potential testers and integrators of this patch. First of all, let's start with a common pitfall: * You have to update your /boot/device.hints, and then reboot. In no other circumstance will the isa-based lm(4) or it(4) be probed. Manually updating the hints with kenv(1) after the system has already been booted has no effect on the isa modules. * Second, since this patch is not only about the framework, but about some Super I/O Hardware Monitoring drivers too, let me once again reiterate on the popularity of the chips that are supported by the lm(4) and it(4) drivers. I have four boxes here, all run FreeBSD and OpenBSD. Let's see what Super I/O chips they have: * AOpen AX4G-N (845G + Intel Pentium 4 Northwood): Winbond W83627HF-AM * ASUS Terminator C3 (VIA CLE266 + VIA C3 Samuel 2): Winbond W83627THF-A * ASUS V3-P5G965 (G965 + Intel Core 2 Duo Allendale): Winbond W83627DHG-A * PCCHIPS V21G (VIA CN700 + VIA C7 Esther): ITE IT8716F-S Out of the above, Winbond W83627* are supported by lm(4), and ITE IT8716F-S by it(4). (Obviously, the drivers support other chips, too. ;) In general, most boards from Taiwanese manufacturers have either a Winbond or ITE Tech Super I/O chips, supported by lm(4) and it(4) respectively; e.g. if you have a Gigabyte or ASUS mainboard, then the probability of you having one of these chips is quite substantial -- consider testing the patch if you are interested. Supermicro boards also feature Winbond chips quite often -- feel free to test. Intel-branded boards, on the other hand, often use an SMBus-interfaced Hardware Monitoring solution. I have none of those boards, so none of the SMBus drivers were ported to FreeBSD yet. Anyhow, I hope this information helps some potential testers and integrators. ;) Cheers, Constantine.
