Make sure dpm is enabled.  add radeon.dpm=1 to the kernel command line in grub.

That message is normal, just a function we haven't implemented yet.

But I agree the numbers look like you are on the bootup clocks for UVD/graphics
or something is going wrong with dpm.

dpm is enabled of course (because I set radeon.dpm=1 and because 3.13 should
have dpm enabled by default afaik).
When using UVD with dpm set to auto it switches from the lowest state to the
highest lots of times, again and again.
*Anyway* when I did run the attached benchmark I forced dpm to "high" before
starting.

I applied 'glx: Add support for the new DRI loader entrypoint' to
xorg-server-1.14.4 and I updated the rest of the graphic stack to latest
snapshot from git master: nothing changes.

While the test was running I got a "Bus error":

Fontconfig warning: "/etc/fonts/conf.d/50-user.conf", line 14: reading
configurations from ~/.fonts.conf is deprecated.

Also I noticed that despite I did "echo high >

I still get lots of power states switching in dmesg.

Please see attached dmesg.

I also noticed lots of "HDMI: ELD buf size is 0, force 128" and "HDMI: invalid

attached using DVI, not HDMI.

This is probably related to dpm and gpu clocks - if I run "vblank_mode=0
glxgears" in parallel with the benchmark the results are significantly better
for me:

w/o gears:

MPEG DECODING (1920x1080): 13 frames/s
MPEG DECODING (1280x720): 13 frames/s
H264 DECODING (1920x1080): 12 frames/s

with gears:

MPEG DECODING (1920x1080): 77 frames/s
MPEG DECODING (1280x720): 118 frames/s
H264 DECODING (1920x1080): 51 frames/s

Setting power_dpm_force_performance_level to "high" doesn't really work for me
in this case - AFAICS the driver resets it back to "auto" when the benchmark
starts, probably when switching to uvd state.

As far as I can see it's actually illegal API usage in qvdpautest. It's trying
to read from uninitialized video surfaces, which is not guaranteed to work.
Swapping around the order of tests so that it does the PutBits test first fixes
it.

As Vadim correctly noted forcing any power state doesn't work here, because we
need to switch to the UVD power state anyway.

BTW: Is this a regression?

^^ very valuable comment, thx.

So do I get that right that generation 3D load affects UVD decoding performance
here?

Thx for the into. qvdpautest is badly written in many aspects (takes to many
time, is inaccurate etc...). Would be nice if somebody could sit down and
either write something new from scratch or start to improve it.

Some rather stupid command-line tool with a couple of options for testing
different decoding profile and output methods should be perfectly sufficient.

Yes, I think the explanation of the difference in benchmark results is that
glxgears triggers higher gpu power level, probably the benchmark alone simply
doesn't provide enough load for that or maybe something is wrong with dpm
logic. Here is what I see while running the benchmark:

w/o gears:
power level 0    sclk: 45000 mclk: 120000 vddc: 900 vddci: 975 pcie gen: 2
with gears:
power level 2    sclk: 100000 mclk: 120000 vddc: 1219 vddci: 975 pcie gen: 2
uvd clocks are the same in both cases:
uvd    vclk: 72000 dclk: 56000

when the system is completely idle I see the following values:
uvd    vclk: 0 dclk: 0
power level 0    sclk: 30000 mclk: 15000 vddc: 825 vddci: 850 pcie gen: 2

With kernel 3.13, the driver retains the user selected performance level across
state changes.  Additionally, when using a UVD state, the sclk and mclk are
always forced to their highest levels.  This isn't reflected in the debugfs
output since that just prints the unpatched power state.  Does plain video
playback work ok (i.e., not qvdpautest)?

[Bug 71448] [UVD] qvdpautest is very slow on radeonsi (HD 7950)

Alex from the tests I did 3.13 doesn't seem to behave the way you described.

With power state set to "high", desktop effect OFF and no glxgears:
MPEG DECODING (1920x1080): 5 frames/s
MPEG DECODING (1280x720): 21 frames/s
H264 DECODING (1920x1080): 8 frames/s
H264 DECODING (1280x720): 5 frames/s

With power state set to "high", desktop effect OFF and glxgears:
MPEG DECODING (1920x1080): 77 frames/s
MPEG DECODING (1280x720): 117 frames/s
H264 DECODING (1920x1080): 16 frames/s
H264 DECODING (1280x720): 91 frames/s

With power state set to "high", desktop effect ON and glxgears:
MPEG DECODING (1920x1080): 77 frames/s
MPEG DECODING (1280x720): 117 frames/s
H264 DECODING (1920x1080): 51 frames/s
H264 DECODING (1280x720): 91 frames/s

It seems even glxgears wasn't able to keep highest power state in all tests:
enabling desktop effects was enough to keep higher state in the second-last
test.

What do you mean by "plain video playback"? If you mean without using vdpau it
works flawlessly.

Just play a video with vdpau using mplayer or some other app that supports
vdpau.  I'm wondering if perhaps the way qvdpautest works causes the driver to
switch between power states too often so the clocks never get a chance to
stablize.

I used to use mplayer benchmark before switching to qvdpautest, unfortunately
results are not comparable because other peoples have to have the very same
videos (which tends to go offline after some months).
vdpautest is the right way to go in my opinion, we just need someone to fix the
remaining bugs.

kwin desktop effects ON and glxgears
mplayer2 -benchmark -vo vdpau -vc ffmpeg12vdpau -nosound 1080p25.ts

BENCHMARKs: VC:   5.073s VO: 105.829s A:   0.000s Sys:   3.263s =  114.164s
BENCHMARK%: VC:  4.4433% VO: 92.6989% A:  0.0000% Sys:  2.8578% = 100.0000%

Mplayer better shows the behaviour I wanted to show with the previous video: it
takes *ALOT* of time to start the benchmark, but then it's quite fast. At least
while glxgears is running: in fact without glxgears it takes ages.

Here is a second video showing the lag I'm talking about:
http://www.youtube.com/watch?v=BDhB61U9S0A
As you can see when it starts decoding is quite fast.

Power state high doesn't help.

qvdpautest + 3.14-rc0 + AUTO + KWIN OFF:

qvdpautest + 3.14-rc0 + HIGH + KWIN OFF: the same

qvdpautest + 3.14-rc0 + HIGH + KWIN ON + glxgears:

MPEG DECODING (1920x1080): 77 frames/s                                          
MPEG DECODING (1280x720): 117 frames/s

Fortunately I noticed a great improvement with 3.14: I don't have the huge lag
before the start of the benchmark and glxgears doesn't freeze anymore like in

Fix.

Sorry that it took me so long to find this. It's a rather simple issue that the
IRQ support for UVD on SI wasn't activated.

With this patch in place I now get 52fps with 1080p H264 decoding.

Are you sure this lockup isn't caused by some other upgrade you did such as
mesa?  The patch works fine here.

Sounds like we can close this bug.

The GPU lockup of the GFX ring seems to be unreleated, please open up a new

Yes i am sure. I run qvdpautest before and after upgrade kernel. But now i run
test again several times and all fine, no more gpu lockup.

If this happen again i open new bug.
