--- Comment #25 from Chernovsky Oleg adonai@xaker.ru --- (In reply to Christian König from comment #24)
Now take a look at si_set_uvd_clocks in si.c. Especially try to figure out if the first or the second call to radeon_uvd_send_upll_ctlreq fails.
Additional to that please install radeontool and get me the content of the CG_UPLL_* registers. E.g. I need the output of:
radeontool regmatch 0x634 radeontool regmatch 0x638 radeontool regmatch 0x63c radeontool regmatch 0x644 radeontool regmatch 0x648 radeontool regmatch 0x650
Thanks, Christian.
It's the first call to this function in si_set_uvd_clocks that's failing. Doesn't work in bypass mode? Or maybe too low mdelay before call?
[ 2.237380] [drm] At call 1 [ 3.278457] [drm] At call 2 [ 3.288474] [drm] Passed!
