The warn in question is
static u32 nvkm_mc_intr_mask(struct nvkm_mc *mc) { u32 intr = mc->func->intr_mask(mc); if (WARN_ON_ONCE(intr == 0xffffffff)) intr = 0; /* likely fallen off the bus */ return intr; }
Which is basically a sign of total death. Is this new with 4.5-rc1, or is this the first time you've tried reclocking this chip?
this was the first time I tried reclocking. When the GPU is idle, reclocking is successful and the same WebGL app runs a lot smoother. BTW, the machine I tried was a Zotac ZBOX MiniPC ID41 series.
I also have a question related to reclocking on other chips.
Zotac ZBOX ID84 series:
# lspci -s 02:00.0 02:00.0 VGA compatible controller: NVIDIA Corporation GF119M [GeForce GT 520M] (rev a1) # lspci -s 02:00.0 -n 02:00.0 0300: 10de:1050 (rev a1)
Zotac ZBOX ID86 series:
# lspci -s 02:00.0 02:00.0 VGA compatible controller: NVIDIA Corporation GF119 [GeForce GT 610] (rev a1) # lspci -s 02:00.0 -n 02:00.0 0300: 10de:104a (rev a1)
All three boxes are out of production now, but we're using about 20,000 (really, about twenty thousand) in total of them at my company. Nouveau supports them just fine, the main application is video decoding/playing and it works very well for the supported codecs reported via vdpauinfo. Is there a known roadmap to support reclocking on these latter two?
Thanks, Zoltán Böszörményi

Hi,
I was trying to use re-clocking with nouveau in 4.5.0-rc1 with:
# echo "0f" >/sys/kernel/debug/dri/0/pstate
while Chromium with a WebGL app already running. (www.playmapscube.com)
The video chip in question is:
03:00.0 VGA compatible controller: NVIDIA Corporation GT218 [ION] (rev a2)
or in numbers:
03:00.0 0300: 10de:0a64 (rev a2)
It is an integrated chip on the mainboard.
The result was:

I guess this is possibly a race condition.
