full dmesg
I've recently bought a ASUS STRIX-RX470-O4G card for my desktop, running on
Debian Stretch and a custom built 4.9 kernel.=20
The card seems to be running okay. I haven't got random glitches, crashes or
lockups yet.
... but I found this in my dmesg:=20
[ 1.226688] Can't find requested voltage id in vdd_dep_on_sclk table!
"pp_dpm_pcie" prints:
0: 2.5GB, x8 *
1: 8.0GB, x16=20
It seems to be running in PCIe x8 mode, and it should be able to run at x16.
"amdgpu_pm_info" prints:=20
GFX Clocks and Power:
300 MHz (MCLK)
300 MHz (SCLK)
GPU Temperature: 37 C
GPU Load: 0 %
UVD: Disabled
VCE: Disabled
Note UVD and VCE claims to be disabled but thats not what my dmesg seems sa=
ys:
[ 1.377965] [drm] UVD initialized successfully.
[ 1.225023] [drm] UVD is enabled in VM mode
[ 1.477235] [drm] VCE initialized successfully.
[ 1.225024] [drm] VCE enabled in VM mode
Is something wrong with my system, am I reading this incorrectly, have I se=
tup
my system incorrectly/suboptimal, or is it nothing to worry about?
I think your system is probably fine. The GPU changes the clo= cks dynamically based on GPU load. If the GPU is idle, the clocks automatically go down to= the lowest level. Please try running a GPU intensive application and check amdgpu_pm_info again with the app running.
After stressing the GPU, "the pp_dpm_pcie" switched = back and forth between x8 and x16 depending on the load, so I guess thats fine. The GFX clocks also variate depending on load, and performance seems reason= able everything considered.=20 But I still don't get why the UVD/VCE claims to be disabled? And why it can't seem to find requested voltage id?
UVD and VCE get disabled at runtime to save power. If you run= a video decode or encode task, they will get enabled dynamically. As for voltage, we don't currently print that information in the debugging output as it's tied direc= tly to clocks.

Yep, when I run a movie in VLC it enables UVD in "amdgpu_= pm_info" Well, I'm just ignorant then.=20 Sorry for bothering you guys.
