>Description:
I'm having Asus A7V880 motherboard (AthlonXp, KT880, VT8237) and can't get to work any thermal viewing and control program. I've tried mbmon, healtd, consolehm etc. Some don't work at all (NO HW SENSOR AVAILABLE or simmilar message) or showing constant temperature 255C.
I'v tried to load smb/smbus/*pm modules - no effect, tried to recompile kernel with:
device smbus
device viapm
device smb
device iic
device ic
device iicbus
device iicbb
device iicsmb
no effect. Even NO /dev/smbX device present and 'dmesg | grep smb' or 'sysctl -a | grep thermal' shows nothing.
Then I found, that this south bridge is using 'VIA VT1211 LPC Super I/O' chip for I/O operations accordingly to thermal sensors and there is no driver support in BSD, so the systems do not understand it. But I found that driver for this chip was introduced in OpenBSD 3.8:
"Modified files:
sys/arch/i386/conf: GENERIC
sys/arch/amd64/conf: GENERIC
sys/dev/isa : files.isa
share/man/man4 : Makefile
Added files:
sys/dev/isa : viasio.c viasioreg.h
share/man/man4 : viasio.4
Log message:
Add viasio(4), a driver for VIA VT1211 LPC Super I/O found on
some VIA CPU based boards. The driver provides temperature,
voltage and fan tachometers values through the sysctl interface. "
I've tried to port this driver to FreeBSD but no effect :( can't even compile kernel.
Is it possible to create/port such a driver in FreeBSD? It would be very popular, because I found a lot of simmilar problems on the net...
>How-To-Repeat:
>Fix:
Write own VT1211 driver or port from the OpenBSD (viasio)
