Re: envstat drivers on SUN Ultra-45?

[Julian Coleman <jdc%coris.org.uk@localhost>]

Hi,

After looking at the V240 OFW patches, I had a chance to get back to the
U45.  I currently have patches to fix up the OFW errors and drivers for
the monitoring.  The ADT7462 driver needs the voltage logic and limits
added, but it's enough for me to see:

If you'd like to try it out, I've put the patch and other files at:

  https://ftp.netbsd.org/pub/NetBSD/misc/jdc/sparc64/

"u45.diff" is the patch file, "netbsd" and "netbsd.gdb" is the kernel with
these and "u45-envsys.conf" is the sensor names for /etc/envsys.conf.
"u45.dmesg" is the full dmesg, but relevant lines are:

  [     1.000000] bq4802rtc0 at ebus0 addr 100000-10000f: real time clock
  [     1.000000] seeprom2 at iic0 addr 0x57: psu-fru-prom: size 4096
  [     1.000000] adt7462sm0 at iic0 addr 0x58: ADT7462 system monitor: rev. 0x4
  [     1.000000] adt7462sm0: 5 fans, 4 temperatures, 0 voltages
  [     1.000000] lm95221ts0 at iic0 addr 0x2b: LM95221 temperature sensor
  [     1.000000] lm75a0 at iic0 addr 0x4f: LM75A temperature sensor

I also patched the psu-fru-prom, but I don't see anything useful if I try:

  dd if=/dev/seeprom2 bs=1 skip=0 count=4096 | hexdump -C

whereas I can see the part number and location from one of the others:

  dd if=/dev/seeprom0 bs=1 skip=7168 count=1024 | hexdump -C

I'd be interested to see what numbers you get for cpu1 temperature and fan
speed, because I wonder if my cpu1 needs new thermal paste.

Julian
