Does it also work properly with dc disabled? I suspect a bug
somewhere in the display info that dc generated when no displays are attached.
See smu7_program_display_gap().
Yup, with dc=0 the clock is correctly set.
I'll take a peak (tomorrow) but I suspect it'll probably be more fruitful to
hand it over to the display team.
Thanks,

Are there any displays attached to the secondary card with the mclks
stuck high? If not, does attaching a display help?
Stealing the display from my primary (CZ in this case) does help, and
then putting it back the MCLK remains low.

*Subject:* MCLK defaults high on second card Hi,
I have a setup with a CZ + Polaris10 and on the Polaris10 the SCLK
idles low and the MCLK stays in the 2nd state (1750MHz) but on my
Workstation which has a single 560 in it the card idles at 300MHz
(with the stock
FC27 kernel).
Is there an issue with non-primary cards idling properly?
Doing
echo 0 >
/sys/devices/pci0000:00/0000:00:03.1/0000:21:00.0/pp_dpm_mclk
Doesn't result in low clock rates either.
Tom
