Hi Viswanath. I tested this patch on ChromiumOS's downstream
5.15-based fork. Using ITU-T HEVC test vectors [0] I am seeing
firmware errors "qcom-venus-decoder aa00000.video-codec:video-decoder:
VenusMed : event not sufficient resources". Does this change fix HEVC
decoding for you?

Best regards,
Nathan Hebert
