Hi,
My server (S2600CP) has BMC module and power supply with pmbus function.
When I try to control and monitor with pmbus driver in linux, it fails.
I connected oscilloscope to pmbus connector (SCL, SDA) pins, there was
no signal from pmbus driver.
But when the system went down, there are pmbus signals which may be
generated by BMC.
In x86 server, is pmbus connected only to BMC(ipmi)?
Is it not connected to CPU i2c bus?
is it impossible to monitor power supply with pmbus drvier?
Why not ask on the lm-sensors mailing list, where the kernel sensor
developers are, that wrote this code? That would be the best place for
it.
good luck,
