Opteron 165 on supermicro H8SSL-i

[Hauke Fath <hf%spg.tu-darmstadt.de@localhost>]

Hi,

bringing up netbsd-8 on an Opteron 165 / supermicro H8SSL-i dual-core 
system, I noticed

%  envstat
envstat: no drivers registered
%

Running 'sensors-detect' from a debian 7 'lm-sensors' (linux 3.14) gives me

<snip>
Driver `to-be-written':
  * ISA bus, address 0xac0
    Chip `Nat. Semi. PC87427 Super IO Health Sensors' (confidence: 9)

Driver `adm1026':
  * Bus `SMBus PIIX4 adapter at 0580'
    Busdriver `i2c_piix4', I2C address 0x2c
    Chip `adm1026' (confidence: 6)

Driver `pc87427':
  * ISA bus, address 0xaa0
    Chip `Nat. Semi. PC87427 Super IO Fan Sensors' (confidence: 9)

Driver `k8temp' (autoloaded):
  * Chip `AMD K8 thermal sensors' (confidence: 9)
</snip>

resulting in a 'sensors' output of

which matches the BIOS setup's output nicely. So, we don't attach 
amdtemp(4) for the 165 when we should

[...]
amdnb_misc0 at pci0 dev 24 function 3: AMD NB Misc Configuration
isa0 at pcib0
[...]

I tried adding

adm1026hm* at iic? addr 0x2c	# Analog Devices ADM1026 hardware monitor
adm1026hm* at iic? addr 0x2e	# adm1026hm(4) says 0x2e, lm-sensors says 0x2c

(which has been added for -8, but is not even in ALL), but it does not 
attach.

And neither did adding

nsclpcsio*	at isa?
gpio*		at nsclpcsio?

do anything. There are patches for the openbsd nsclpcsio(4) adding 
support for the PC87427 at 
<http://comments.gmane.org/gmane.os.openbsd.tech/14510>, but the NetBSD 
driver differs widely enough to make the addition non-trivial.

Does the above speak to anybody? Anything elae I can try?

Cheerio,
hauke
