Hi all, here's the third revision of the Host1x/TegraDRM UAPI proposal. The open issues from RFCv2 should be resolved now, so I'm dropping the RFC tag. The series is still only tested with Tegra186 so I'm hoping for people with devices with other chips to test this out. The test suite[1] has been updated for the changes in this revision, and also includes tests for the newly added DMA reservation support. If there are no further issues with the UAPI definition, I'll look at porting other userspace next - hoping for some help with that as well since most of it is for chips I don't have easy access to. The series can be also found in https://github.com/cyndis/linux/commits/work/host1x-uapi-v3.
