>Environment:
FreeBSD 7.0-PRERELEASE
VIA C7 1.5Ghz + CN700 + VT8237R
>Description:
I configure and build kernel with enable viapm driver.
but, kernrl could not detect the VIA VT8237R southbridge on my motherboad(GA-C7V7).
The OpenBSD current viapm.c that support VT8237(same as VT8233).
>How-To-Repeat:
install 7.0 RC2
>Fix:
patched kernel's dmesg >>
viapropm0: <VIA VT8233/VT8235/VT8237/CX700 Power Management Unit> port 0x500-0x5
0f at device 17.0 on pci0
smbus0: <System Management Bus> on viapropm0
smb0: <SMBus generic I/O> on smbus0
isa0: <ISA bus> on viapropm0
Add VT8237 pci-deviceID to viapm.c
(and shrink code very little...)
