Hi Vikash,

This is not just with totem, showtime shows the same issue. If I let the video
play, it plays just fine, however, if I attempt to skip forward, back, or even
play*after* the video has played, then I see the smmu fault

arm-smmu 15000000.iommu: Unhandled context fault: fsr=0x402, iova=0xd51e3e00, fsynr=0x600002, cbfrsynra=0x2a00, cb=6
please log the info about which "iova=0xd51e3e00" buffer is faulting in
this case
I will include the diff that I applied against my kernel, in case this isn't the
correct information, but I get the following output in EL2:

But these logs don't capture, which buffers are causing the IOMMU error.

I'd be interested to see if we can run this test on venus - instead of iris.

Konrad's patches are still floating around somewhere.
