Hi Dafna,

2. Always happened  issue ?  timeout at the beginning or  in processing ?

The commands that I run is:

sudo --user=#1000 /usr/local/libexec/chrome-binary-tests/video_encode_accelerator_tests --gtest_filter=-*NV12Dmabuf*  -->>codec=vp8 >/usr/local/share/tast/data/chromiumos/tast/local/bundles/cros/video/data/tulip2-320x180.yuv --disable_validator

The command sometime succeed but when I run it sequentially then at some point after few attempts I start to get those timeout errors.

It seems mean VP8 encoding function OK, but failed sometimes, did you have check VENC clock info during encoding:

cat /sys/kernel/debug/clk/clk_summary | grep venc:

venc_sel   > it's H.264 clock
venclt_sel  > it's VP8 clock

the enable&prepare count is not 0 during encoding process.

I see that the values are indeed incremented while streaming.
When timeout occurs it is always in the beginning of the encoding. So upon the first call to vp8_enc_wait_venc_done.

Thanks,
Dafna



Thanks
Best Regards

1. Log shows wait IRQ timeout ?

Hi, yes, I get timeout when waiting to the encoder interrupt. The timeout is on vp8_enc_wait_venc_done


2. Always happened  issue ?  timeout at the beginning or  in processing ?

The commands that I run is:

sudo --user=#1000 /usr/local/libexec/chrome-binary-tests/video_encode_accelerator_tests --gtest_filter=-*NV12Dmabuf*  --codec=vp8 /usr/local/share/tast/data/chromiumos/tast/local/bundles/cros/video/data/tulip2-320x180.yuv --disable_validator

The command sometime succeed but when I run it sequentially then at some point after few attempts I start to get those timeout errors.

3. how about IRQ infos?
cat /proc/interrupts | grep vcodec
18002000.vcodec   >> it's H.264 encoder
19002000.vcodec  >> it's  VP8 encoder

I was told you have  met another H.264 encoding failed before, did you find reasons about that ?

No,
But since I see that the google meetup uses the vp8 encoder I decided to test the vp8 first.

I uses the latest firmware.

Hi Dafna,

This state check is useless, the enc result will check in
"vpu_enc_ipi_handler".


Hi, thanks for reviewing. I see that the vpu_enc_ipi_handler only test the msg->status and I see that the states are not tested anywhere except of "skip" state in the h264 enc.

Can't there be a scenario where msg->status is ok but the state is error?
I am testing the vp8 encoder on chromeos and at some point the encoder interrupts stop arriving so I try to figure out why and report any possible error.

Thanks,
Dafna

Thanks
