Hi. We are see a crash when we switch h264 encoder resolutions sometimes. It seems to happen more frequently when the scene is of a higher frequency or activity. This is the output we see:
root@sla-alip:~# [ 96.377003] arm-smmu d40000.arm,smmu-venus: Unhandled context fault: fsr=0x402, iova=0xddbf9000, fsynr=0x33, cb=0

[ 96.515154] qcom-venus c00000.video-codec: system error has occurred, starting recovery
The output is similar to this capture ticket where it is suggested to increase the buffer size, but I don’t know if that helps or not: What do Unhandled context fault messages mean when doing Mipi Capture
Any suggestions would be appreciated.
Thanks,
Kim
