Re: E450 Fan tray noise
I recall that there is a kernel config option (compile time) for a module to handle this. envctrl I assume? I don't have a /dev/envctrl the module fails. What is the major/minor for this device, or where can I find it? -- Ian Cass
Re: E450 Fan tray noise
OK I've delved into this a bit deeper...
It looks like there was a patch to the envctrl driver way back in 2.2.16
which changed the way the driver found the environment controls on the sbus.
- if (!strcmp(edev-prom_name, SUNW,envctrl))
+ if (!strcmp(edev-prom_name, i2c)) {
My Prom returns the names the old way, like this...
ebus0: [auxio] [power] [SUNW,pll] [sc] [se] [su] [su] [ecpp] [fdthree]
[eeprom] [flashprom] [SUNW,envctrl]
So it seems the driver isn't finding the hardware. Prom version problem
perhaps?

Is there anyone with an E450 for whom envctrl works?

I _think_ I included this as a module in the default kernels. Give
modconf a look to see if there's something in the sparc specific modules
(like an env module or something).

Re: E450 Fan tray noise
Eddie's version from a few years back did support E450 but the fan
control never did work properly for that boardset. A while back it was
re-written by somebody at Sun to support a few SME boardsets and the
support for E450 was removed.
At this time, I can vouch for envctrl on CP1400, CP1500 and possibly
Netra-T1/105. Neither SME AX boardsets nor SMCC (E450,E250,etc) are
supported by this driver. Under the sheets they are all very similar,
but the OBP layout seems to change with the seasons and some are more
cryptic than others.
I've been toying with envctrltwo on an E250, but time is scant so I
cannot commit to anything. If somebody decides to work on this I would
not mind speaking with them so we can come up with a better envctrl
infrastructure and possibly leverage the i2c subsystem instead of the
current 'roll-your-own' support.
