Hi Marijn,
Thanks for the patch.
I saw that in your commit msg, you mentioned that 7.x doesn't have
tearcheck in the INTF block -- can you double check that this is correct?
I'm working on SM8350 (DPU v7) and I'm seeing that it does have
tearcheck in INTF block.

Just wondering, how were the lengths calculated for the INTF blocks? The
values in general seem a little off to me.
For example, I'm looking downstream and it seems to me that the length
for the INTF_0 on MSM8998 should be 0x280. Similarly for SC7280, I'm
seeing that length for INTF + tearcheck should be 0x2c4.
Thanks,
Jessica Zhang
